1. GENERAL CONCEPTS ABOUT VENTILATED FACADE SYSTEMS

1.1. VENTILATED FACADES IN THE GENERAL CLASSIFICATION OF "DRY" METHODS OF FACADE FINISHING.

"Dry" systems mean an external protective and decorative screen formed by slab or sheet products. Such products are fixed without mortar or glue, “dry” with the help of special devices (latches, clamps, clips, clips, rivets, etc.).

As a rule, such systems are characterized by the presence of an air gap between the screen and the insulation. Such facade systems with an air gap are called ventilated facades.

Currently, there is a large selection of modern systems of dry facade finishing methods. Analysis of the information collected by the authors made it possible to classify the variety of "dry" facade technologies(rice.

Among the "dry" facade systems, ventilated facade technologies have a wider range of materials. To date, they are being introduced more often compared to the technologies of dry fastening of finishing elements directly to the wall.

They differ from each other mainly in the method of fastening the facing elements to the surface to be finished and the material from which the elements are made.

In Ukraine, many well-known projects have been implemented using facade systems presented in the classification. Their architectural capabilities

attracted the attention of construction specialists in our country and abroad.

The increase in investment in commercial and municipal construction in recent years has led to a marked increase in new construction and renovations.

It is known that the range and range of materials must meet the solvency of the customer. In the above classification of modern facade technologies, one can find an opportunity to satisfy any requirements, from the most modest to the most sophisticated.

1.2. STRUCTURAL AND TECHNOLOGICAL SOLUTIONS

Ventilated facades began to be used in Europe several decades ago. The main functional purpose of a ventilated facade is to protect load-bearing walls from moisture. The result of many years of practice in the use of ventilated facade systems was the emergence of the main option. Its constructive-technological scheme is shown in fig. 1.2.

To prevent the possible blowing of the insulation fibers under the action of the turbulence of the ascending air flow, it is necessary to take measures to ensure wind protection. The following ways of solving this problem are known.

One of them is the device of a windproof layer of non-combustible fiberglass . The disadvantage of this option is the insecurity of the joints between the plates. With a low density of the insulation - insufficient adhesion of the coating material to the fibers of the insulation. This can cause the canvas to peel off and block the air gap.

The second option is the application is rather harsh

fiber boards, which in themselves are already wind protection. Studies by scientists from the Scottish Institute of Occupational Diseases confirm that with an average material density of approximately 100 kg/m3

such a phenomenon as turbulence, practically does not cause emission of fibers.

Rice. 1.2. Structural and technological scheme of a ventilated facade

A certain danger in systems of ventilated facades is represented by moisture that has entered the air cavity between the screen and the inner layer of the wall (insulation). Even slight moisture can adversely affect both the thermal properties of the insulation,

and at the operation of the system as a whole, and lead in the future to the need to replace its structural elements.

There are several ways to deal with this phenomenon.

The first is the placement of a vapor-removing membrane on the surface of the inner layer of the wall. . Its disadvantages include the flammability of membranes of this type, the inability to protect building structures as effectively as insulation does, and the likelihood of membrane peeling during operation.

The second is sealing expansion joints between screen elements . It also has its drawbacks, since the service lives of sealing materials and screen elements (tiles) are different, and it is almost impossible to replace the sealant.

Third, for today, probably best option lies in the correct choice of the size of the elements of the screen and gaps. So the experiments of the Norwegian Building Research Institute gave the following result: with an air gap width of about 40 mm and a distance between the screen elements of 3 mm, drops of oblique rain do not enter the system at all due to the water film formed under the action of surface tension.

When choosing a heater for ventilated facade systems, it is necessary to take into account its physical and mechanical properties, including density.

The device of ventilated facades is made

"dry" way.

An example of the technological sequence of installation of a ventilated facade system is shown in fig. 1.3 - 1.6.

Brackets are attached to the wall of the building with anchor nuts or dowel bolts, and guides to the brackets are fastened with rivets and bolts (Fig. 1.3). For com-

Introduction

In accordance with the assignment for the course design issued by the Department of Construction Technology of the Odessa State Academy of Civil Engineering and Architecture, a course project was completed on the topic: “Technological map for the installation of a ventilated facade system “APM - Profile” with facing with metal volumetric cassettes during the construction of a residential building in the city Odessa. The project was developed in accordance with the requirements of state building codes and rules and other regulatory and technical documentation. Modern technologies, materials and building systems were applied in the project, which made it possible to obtain higher strength, protective, heat-insulating, and aesthetic indicators.

Currently, there are a large number of varieties of systems, facade insulation. Such as: a system of facade insulation with a wet method, as well as ventilated facade systems with various protective, decorative, facing materials. Technologies for such systems have been developed by: CERESIT, ATLAS, RUUKKI, SCANROC APM-Profile, etc. Ventilated facades began to be used in Europe several decades ago. The main functional purpose of a ventilated facade is to protect load-bearing walls from moisture. The result of many years of practice in the use of ventilated facade systems was the emergence of the main option. Its constructive technological scheme is shown in Fig. one.

Ventilated facades are the most efficient multi-layer systems in terms of their physical and construction parameters, having a wind and rain barrier. When installed correctly, they ensure long-term functional reliability of buildings.

The main advantages of ventilated facades include:

* Ventilated facades are the most efficient, multi-layer systems in terms of their physical and construction parameters, having a wind and rain barrier. When installed correctly, they ensure long-term functional reliability of buildings.

* Existing technologies plate production and installation technology make it possible to use facade plates for facing high-rise buildings 50 m and above.

* By separating the functions of cladding, insulation and supporting structure, complete protection of the building from adverse weather factors is achieved.

* All moisture penetrating through the open joints of the cladding is removed by the circulating air flow. Exterior walls and insulation remain dry and fully functional.

* Temperature loads of the supporting structure are almost completely eliminated. Heat loss in winter and overheating in summer are minimized. The destructive temperature loads of the supporting structure are significantly reduced. Increases the life of the building.

* Forced cold bridges are blocked, a comfortable room temperature is maintained. In regions with a hot climate, the energy consumption for air conditioning is reduced.

* Professionally installed facade systems provide additional noise protection, as well as a comfortable humidity regime of buildings.

* The use of facade systems makes it possible to save irreplaceable Natural resources(coal, oil, gas).

* Systems "APM - Profile" have sufficient mechanical strength for the perception of dynamic loads with an intensity of at least 9 points on the MSK-64 scale and can be used for buildings of mass construction in almost all areas of seismic hazard.

Economic advantages of facade systems"APM - Profile".

Controlled production costs

Long service life

Low need for technical and aesthetic care

Great energy saving potential

Technical advantages of facade systems"APM - Profile".

fire protection

Facades with the use of metal substructures manufactured by the APM-Profil plant, facing slabs and panels belonging to the class of non-combustible materials, fasteners meet the building fire safety requirements.

Anti-noise protection

The use of facade systems leads to a significant improvement in anti-noise protection. Improvement of sound insulation of enclosing structures can reach values ​​from 5 to 14 dB.

Durability

Quality is ensured by the use of effective binders, stable dyes, precise execution of the production cycle and professional installation. Year-round construction cycle The absence of "wet" processes makes it possible to carry out work at any time of the year.

rain barrier

The structures of the facade systems "APM - Profile" reliably protect against the action of rain with wind. The first barrier is the facing board, the second is the circulating airflow within the system.

Local repair

Consequences of vandalism, accidents, etc. easily repaired by replacing the damaged lining.

energy saving

The ability to simultaneously produce facade decoration and thermal insulation of external walls.

1 . Sequence of work

Preparing the building for insulation

Prior to the start of work on the insulation of the facade and the installation of facade systems, it is necessary to conduct a complete study of the facade, on which the substructure will be mounted.

The study must necessarily include such works as: conducting a geodetic survey to obtain the dimensions of the building, identifying the type and condition of the bearing walls of the building; testing the anchor dowel, with which the structure will be attached. Whether the dowel will hold well in the wall or the wall is too old and the design of the ventilated facade will not withstand, this test determines the maximum permissible load. Based on these studies, a project is being developed for the insulation and installation of a ventilation facade for this building. The basis of the facade insulation project should contain the following: Thermal engineering assessment of the object before insulation. Based on this assessment, the thickness of the heat-insulating layer is determined. Type, thickness, location plan and fastening of thermal insulation. Heat-insulating plates are mounted close to each other. They are fastened in a checkerboard pattern so that there are no continuous joints between them, with special dish-shaped dowels. The number of dish-shaped dowels is taken according to the recommendations of the thermal insulation manufacturer.

To perform work, the building is divided into sections and the order and sequence of moving the installers from one section to another is determined. In this course project, it was decided to divide the building into 2 captures, which will be performed in parallel.

Installation of cradles

Since the residential building has 10 floors, construction and installation work will be carried out from cradles.

The AB-450/650 electric suspended cradle is a scaffolding tool for organizing workplaces at height and is designed to lift people, tools and building materials to the workplace when performing external works on the facades of buildings and structures up to 240 meters long. The cradle platform can be assembled from three modules with dimensions of 1, 2 and 3 m. The length of the cradle platform can be up to 14 meters.

Support bracket mounting

Brackets are attached to the wall of the building with anchors or dowel bolts, and guides to the brackets with rivets and bolts. Adjustable brackets are used to compensate for irregularities in the building wall and to ensure that the rails are perfectly vertical. Brackets allow you to adjust the horizontal and vertical alignment load-bearing structure, including compensation for surface irregularities of the main wall, fig. 2.

Fig.2 Mounting of bearing brackets

Installation of brackets for a vertical profile (bearing half-timbered houses) is carried out according to the project in the following sequence:

The design of structures is linked to the actual building envelope on the basis of a writ of execution, geodetic surveys, geometric measurements;

Vertical (horizontal) beacons are installed along the lines of supporting half-timbered houses with a step according to the project, along marked verticals and horizontals;

Marking of mounting holes for bearing brackets is carried out (according to the project);

Holes are drilled in the wall (with a mechanized rotary tool, impact is not allowed!);

Mounting on the wall of the base part of the supporting brackets, with a reinforcing washer previously installed inside the bracket, is carried out with anchor dowels using an electric screwdriver with a special nozzle;

A paronite gasket is placed under each base part of the bracket against the wall. (It is possible to install gaskets between the parts of the bracket);

A reinforcing washer is installed inside each bracket.

An example of a bracket is shown in Fig.3.

Fig 3. Bracket

The nozzles are placed vertically (along the previously installed beacons) and fastened using galvanized M8 bolts with nuts and washers;

On both sides, the attachment is fixed to the base part of the bracket using self-tapping screws for metal (4.2x16) along the axis bolted connection, not less than 10 mm from the lower plane of the telescopic part of the bracket.

Mounting guides

The guides are used for attaching facade cassettes to them. The vertical row of rails is mounted starting from the bottom section. All subsequent rows are assembled and installed according to the first reference row. A reference rail of the same length as the module is used to provide the required distance between the rows of rails fig.4.

Fig.4. Installation of vertical rails

1. Installation of the load-bearing fachwerks of the system is carried out on the load-bearing and auxiliary brackets. Fastening is carried out using galvanized self-tapping screws for metal (on both sides of each bracket, or on the lower shelves of the vertical profile).

3. When installing vertical profiles (framing), it is necessary to leave a temperature gap between them for the linear expansion of the profile - 10-15 mm.

4. If necessary, the connection of half-timbered houses is made with nozzles of the appropriate profile using self-tapping screws for metal (at least 4.2x16)

Insulation mount

It is necessary to make sure that there is a certificate confirming the quality and compliance of the physical and mechanical properties of the insulation (passport for the batch) with the adopted design solution.

Installation of insulation boards begins with the bottom row, which is installed on start profile, plinth (Fig. 5) or other appropriate design, and is conducted from the bottom up.

Fig.5. Plinth profile installation

In places where the plinth profile is not firmly attached to the wall, washers of appropriate thickness are installed. The plinth profiles are interconnected using plastic connecting elements. At the corners of the building, the base profiles are joined with oblique cuts (Fig. 6). Their connection must be made using plastic connecting elements.

Rice. 6. Docking plinth profiles in the corners of the building

If the insulation boards are installed in 2 rows, the seams should be tied. Insulation plates should be installed tightly to each other so that there are no voids in the seams. If voids cannot be avoided, they must be carefully sealed with the same material. The entire wall (with the exception of openings) must be covered continuously over the entire surface with insulation, the thickness established by the project. The insulation plates are fastened to the base with plastic plate-type dowels with spacer rods (Fig. 7. (a, b, c)

Rice. 7. A. drilling holes, B. fixing the dowels, C. fixing the dowels at the corners

In our case, due to the use of a wind and moisture protective film, the installed insulation boards are first attached to the base with only two dowels each plate, and only after covering several rows with a film, the remaining (two) dowels provided by the project are installed. Film panels are installed with an overlap of 100 mm.

Facade cladding is made with slabs, the basic dimensions of which are 600x600x10mm

2. The variant of the location of the plates in the plane of the facade is determined during the development of design estimates. If it is necessary to use facade slabs of other sizes, according to the project, they are marked and sawn from the wrong side.

3. Sawing of boards should be carried out on a specialized cutting table that ensures the geometric accuracy of the work, using special sawing equipment (circular saw with replaceable cutting discs, guide and dust catcher). The cutting table must be located indoors or under a canopy, excluding the ingress of precipitation.

4. In the absence of a dust-collecting device, it is obligatory to clean the cut from dust with a dry rag or blow it with air.

Facade cassettes "Profile" are voluminous metal panels, which are a metal structure with sheets bent on four sides. They are made from a thin galvanized sheet with a polymer coating and are produced by bending on high-performance computerized equipment supplied from Finland, which makes it possible to achieve high accuracy and High Quality corners, surfaces and contour shapes.

The vertical seams of the cassettes are usually made open, but cassettes can also be joined close to each other.

The size of the vertical seam for cassettes "Profile 1000" should be no more than 30 mm. The vertical load-bearing profile made of galvanized steel does not have a colored overlay.

The size of the vertical seam for the Profile 2000 cassettes varies from 0 to 60 mm. The vertical load-bearing profile made of galvanized steel has a colored overlay.

If the width of the cassette is more than 60 mm, then the cassettes are fastened using an intermediate vertical profile.

It is recommended to drive screws into the carrier profile mechanized using an electric screwdriver with a special centering nozzle that ensures that the axis of the screw to be screwed corresponds to the center of the hole; - tight tightening of screws is not allowed. After tightening is complete,

loosen the tension of the screw by turning on the return stroke of the screwdriver 0.5-1 turn back;

Drilling points when fastening in the APM-Profile system do not need additional protection from corrosion, since the access of external aggressive influences in places of violation of the protective layer is limited by tight pinching of the connected elements with a galvanized rivet. In addition, volatile zinc compounds formed during drilling form an additional protective covering ferrous metal, (Fig.9.)

Rice. 9. Installation of natural breaded granite slab

Installation of the APM-Profile facade system must be carried out in the following sequence:

Posted on http://www.allbest.ru/

After marking the places for mounting the brackets, proceed with their installation (Fig. 10). To do this, drill holes in the wall with a diameter corresponding to the diameter of the dowel. Install the dowel in the hole and hammer anchor bolt, while providing a thermal break between the bracket and the wall using special gaskets.

Posted on http://www.allbest.ru/

Install insulation (in the case of a ventilated facade). The insulation is installed tightly, without gaps. To fix the insulation to the wall, use special pressure disc anchors. The number of anchors is at least 5 pcs. on the square meter walls (Fig. 11).

In the case of using a windproof film together with a heater, fasten the film to the wall (through the heater) with the same dish-shaped wall anchors. Consumption of anchors for wind protection: 2-3 anchors per square meter.

After that, you can proceed with the installation of horizontal guide profiles (Fig. 12) (section according to the project). Install plumb profiles. The number of self-drilling screws is at least 2 for each bracket. The brand of the self-tapping screw is selected depending on the thickness of the metal of the bracket and the guide profile.

After installing the horizontal profiles, proceed with the installation of the vertical hat profiles. (Fig. 13) Mount the profiles from the left upwards (along the route of fastening the cassettes).

Posted on http://www.allbest.ru/

Carefully measure the axial distances between the profiles. Types of profiles and their sections are determined by the project.

Then you need to install starting bar(Fig. 14). to start mounting the cassettes Simultaneously with the fastening of the strip, install an additional element for slopes and a decorative color overlay on the main vertical profiles.

Posted on http://www.allbest.ru/

The protective film is removed from the decorative color overlay as the cassettes are mounted (Fig. 15). The film is removed first in the area of ​​the joints of the cassettes. The film is removed from the entire surface of the cassette after the final assembly of the facade fragment (during the dismantling of scaffolding). The film does not remove well from the surface of the cassette if it has been exposed to low temperatures or summer sunlight. The recommended film removal period is no more than one month.

Posted on http://www.allbest.ru/

It is necessary to start the installation of the facade cassette in the direction from the left upwards (Fig. 16). The lower edge of the cassette is snapped onto the starting bar, the upper edge is fixed to the vertical rails with self-drilling screws. The type of self-drilling screw is selected according to the thickness of the cassette, the vertical guide and the height of the head.

Posted on http://www.allbest.ru/

After that, you need to install the cassette to the right of the first (starting) cassette (Fig. 17). The correct size of the vertical seam (rust) is provided by a template that is installed between the cassettes and removed after the right cassette is fixed in the design position.

Posted on http://www.allbest.ru/

Then mount the cassette on top of the starting cassette (Fig. 18). Using a theodolite, check the correctness of the vertical edge of the first row of cassettes. In the future, check the vertical of the first row of cassettes every two vertical rows. After that, continue installation according to the above diagram.

Posted on http://www.allbest.ru/

The places where the facade cassettes adjoin the window openings should be closed with specially made additional elements. Fastening of additional elements to the window vertical guides and to the window is carried out with special painted self-drilling screws or rivets. Additional window frame elements must provide unhindered ventilation in the air gap. For this, holes are provided in the flashings of the jumpers.

Instead of additional elements, it is possible to install corner facade cassettes (Fig. 19).

Additional elements are cut and bent in place during installation.

Do not use a tool that generates hot sparks and burns the end surface of the sheet. Drilling chips and other debris must be swept away or, if necessary, washed off immediately after the operation.

The principal device of a hinged ventilated facade

A well-designed, hinged ventilated facade will protect the walls for many decades. But often installers, trying to reduce the cost of this complex, and therefore rather expensive system, replace some materials with others and deliberately violate the rules.

About what such false savings can result in and how to avoid mistakes when installing a hinged ventilated facade, and will be discussed in this article.

A well-designed and well-installed hinged ventilated facade will not need to be repaired for at least 30 years. At the same time, the choice of the facade system should be approached rationally. So, the basement of a building, as a rule, is more reasonable just to tile. This will significantly reduce the cost of finishing.

Finishing buildings with hinged ventilated facades is becoming increasingly popular, both in private housing construction and in the construction of commercial buildings. Such a system is a kind of "coat" for the house.

Attached directly to the walls basalt insulation protected by a special wind and moisture protective membrane. Facing slabs (it can be porcelain stoneware, natural or agglomerated stone, metal cassettes, cassettes made of composite materials, fiber cement panels, steel or aluminum structures, etc.) are mounted on a supporting frame with some clearance. Its value (in the range from 20 to 40 mm) is determined in each case to ensure optimal air exchange.

The thickness of the insulation is selected based on the requirements for thermal protection of buildings. When these conditions are met, the dew point is transferred from the supporting structure to the insulation.

The wrong choice of insulation and its illiterate installation lead to the fact that the material gets wet and falls, clogging the ventilation gap.

Advantages and disadvantages of using a hinged ventilated facade

What is the advantage of such a seemingly complex and, therefore, expensive façade finishing system? Primarily, this design does not allow condensation to accumulate either on the surface of the wall or inside it. The air gap is a kind of temperature buffer, thanks to which the facades do not freeze through in winter and do not overheat in summer, and this helps to significantly reduce heating and air conditioning costs. Snow, rain, hail and other realities of our difficult climate do not violate the integrity of the cladding, which, by the way, cannot be said about the most common finishing material - plaster. Properly installed hinged facade will last more than 50 years.

The system of hinged facades allows finishing buildings of rather complex shapes. In the hinged cladding, you can embody any designer fantasies. But some elements are too labor intensive.

And yet, despite the obvious advantages, ventilated facades have not yet become widespread in suburban construction. Many are put off by the seeming high cost. Yes, 1 m² of such cladding will cost at least 2,000 rubles, and if you use natural stone, the price can reach 6,000 rubles. and even more. But it is important to consider that the operation will not cost anything. As practice shows, after 5-10 years, the hinged facade fully pays for itself.

Of course, a curtain wall system will only work if it is well designed and well installed. Theoretically, a ventilated facade system should be included in the design of the house, so that there is time for calculating the supporting structure and ordering facing slabs. But in practice, this is not always the case. Often it is necessary to “dress” an already rebuilt building in a hinged finish. In this case, the material of the walls must be taken into account. Support brackets for metal purlins hold best in concrete and solid brick. Things are a little worse with hollow bricks. But cellular concrete will require the selection of special and, as a rule, expensive fasteners. To finish walls made of loose, porous materials, it is more expedient to choose a system of “wet” facades (plastering or tiling).

To minimize the work of trimming the slabs, it is important to accurately calculate the size of the module (cell) when designing the facade system. It is by no means equal to the size of the panel itself. It is necessary to take into account gaps with a width of 5 to 10 mm (depending on the type of cladding).

We also note that facing tiles of small sizes (300 x 300 or 400 x 400 mm) are not economically viable - too many fasteners will be required for its installation. Yes, and such a wall does not look very good - the facade of the house will resemble a sheet of a school notebook in a box. A tile of 600 x 600 mm is considered optimal, but it is important to consider that this is an average size. The actual spread from different manufacturers is from 595 x 595 to 610 x 610 mm. Having given preference to a particular collection, you should find out its exact parameters.

1. Brick wall; 2. Bracket (bracing fasteners); 3. The gasket is thermally insulating; 4. Anchor dowel; 5. Main horizontal profile; 6. Main vertical profile; 7. Vertical intermediate profile; 8. Klyammer ordinary; 9. Klyammer starting; 10. Heat-insulating material (insulation); 11. Hydro-windproof vapor-permeable membrane; 12. Thermal insulation fasteners (plastic dish-shaped dowel); 13. Facing tiles; 14. Exhaust rivet.

Ventilated facade fixing systems

Detailed consideration requires the choice of fasteners. As you know, there are two mounting systems - hidden and open.

The first option is metal clamps covering the plate from above and below. The second is anchor bolts that are inserted into non-through holes drilled in the slab and open there like flower petals.

Sometimes mounting elements do not spoil the appearance of the cladding, but, on the contrary, add expressiveness to it.

The use of a hidden fastening system is far from always justified: for example, in areas of the facade that carry a high aesthetic load. And the point is not only that this fastener costs twice as much as the visible one. If the tile fixed in this way is damaged, the entire vertical row will have to be disassembled for repair. Replacing a cladding unit that has been installed openly is uncommonly easier.

Clamps painted to match the color of the tiles are almost invisible on the facade

Poor quality fasteners lead to the loss of facing tiles.

Heaters for suspended ventilation facades

The next important issue is the choice of thermal insulation. Only insulation can be placed under the hinged cladding, which has a technical certificate from the Gosstroy of Russia, allowing its use specifically in ventilated systems. Mineral wool is considered optimal in all respects. The use of non-core materials (for example, glass wool) will lead to the fact that the insulation is saturated with moisture, becomes heavier and settles, reducing or even blocking the air gap.

For guard thermal insulation material only a special vapor barrier membrane can be used

If you try to protect the thermal insulation with polyethylene or foil (that is, materials that do not allow vapor to pass through), then this will not only not solve the problem, but will also disrupt the operation of the ventilated facade, which, as you know, should “breathe”. The insulation can only be covered with a special one-sided vapor barrier membrane: it will pass the moisture released by the walls to the outside, but prevent atmospheric moisture from penetrating inside.

In addition to the insulation, an important role in providing thermal protection is played by thermal breaks - gaskets installed between the brackets and the wall. They must be made of materials with a low thermal conductivity: polypropylene, polyamide, comatex, etc. Paronite gaskets are not allowed, since it does not have thermal insulation properties.

Sometimes installers use special seals that are designed to dampen vibrations and keep the cladding from lateral shift. But their use leads to a decrease in the period of maintenance-free operation of the system, since the seals have a short working life (about 10 years). The reduction of vibration and the exclusion of lateral shift of the facing panels must be ensured by the design of the fasteners.

Installation of ventilated facades

Unfortunately, even the most competent project of a ventilated facade can be nullified by poor-quality installation. The most common mistake is a violation of the geometry of the facade. The cladding should be even, even if the relief of the walls is far from ideal. In addition, the panels should not move relative to the vertical and horizontal axes.

Paradoxical as it may seem, a very common mistake is to install fasteners directly into the masonry seam of wall elements.

Installation of a ventilated facade. The surface of the cladding must be perfectly flat, with exact observance of the thickness of the seams.

Failure to comply with the normative thickness of the seam leads to the fact that the tiles begin to put pressure on each other, crack and fly off. And if the tile is mounted with a deviation from the plane, it will be noticeable in sunlight.

Many builders sin by non-compliance with the standard thickness of the seam. Installed end-to-end, the tiles, due to temperature deformations, begin to put pressure on each other, crack and fall out. And the insulation, in the absence of proper ventilation, gets wet, freezes and slides off the walls. Too large a gap between the cladding panels will lead to excessive wetting of the thermal insulation by atmospheric precipitation.

Particular attention should be paid to the design of window openings.

Now on the Russian market there are many types of hinged facades. Unfortunately, many domestic manufacturers follow a simple path, exactly copying foreign systems. Meanwhile, what works well in the mild climate of Germany or France may not survive our long winters. The thickness of the insulation (and hence the distance from the cladding to the wall of the building) in Russian weather conditions should be significantly higher than in Europe.

In addition, some companies, in an effort to reduce the cost of the system, often use dubious materials in the construction, in particular galvanized steel, which is poorly protected from corrosion. The best metals for ventilation facades lathing are stainless steel and aluminum. But for fixing plates, especially heavy ones, only stainless steel is suitable. Aluminum brackets do not have the necessary strength.

3 ORGANIZATION AND TECHNOLOGY OF WORK PERFORMANCE

PREPARATORY WORK

3.1 Prior to the start of installation work on the installation of a ventilated facade of the FS-300 system, the following preparatory work must be carried out:

Rice. 2. Scheme of organization of the construction site

1 - fencing of the construction site; 2 - workshop; 3 - material and technical warehouse; 4 - working area; 5 - the boundary of the zone dangerous for finding people during the operation of facade lifts; 6 - open storage area for building structures and materials; 7 - lighting mast; 8 - facade lift

Inventory mobile buildings are installed at the construction site: an unheated material and technical warehouse for storing elements of a ventilated facade (composite sheets or panels ready for installation, insulation, a vapor-permeable film, structural elements of a supporting frame) and a workshop for manufacturing cladding panels and framing the completion of facade cladding in construction conditions;

They inspect and assess the technical condition of facade lifts, mechanization tools, tools, their completeness and readiness for work;

In accordance with the project for the production of works, facade lifts are installed on the building and put into operation in accordance with the Operation Manual (3851B.00.00.000 RE);

On the wall of the building mark the location of the beacon anchor points for the installation of load-bearing and support brackets.

3.2 Facing composite material is delivered to the construction site, as a rule, in the form of sheets cut to the design dimensions. In this case, in the workshop on the construction site, with the help of hand tools, blind rivets and cassette assembly elements, facing panels are formed with fasteners.

3.3 It is necessary to store sheets of composite material at the construction site on beams up to 10 cm thick laid on level ground, with a step of 0.5 m. If the installation of a ventilated facade is planned for a period of more than 1 month, the sheets should be shifted with slats. The height of the stack of sheets should not exceed 1 m.

Lifting operations with packed sheets of composite material should be performed using textile tape slings (TU 3150-010-16979227) or other slings that prevent injury to the sheets.

Do not store the cladding composite material together with aggressive chemicals.

3.4 In the event that a facing composite material arrives at the construction site in the form of finished facing panels with fastening, they are placed in a pack in pairs, with their front surfaces facing each other so that adjacent pairs are in contact with their rear sides. Packs are placed on wooden linings, with a slight slope from the vertical. The panels are laid in two rows in height.

3.5 The marking of the installation points of the bearing and supporting brackets on the wall of the building is carried out in accordance with the technical documentation for the project for the installation of a ventilated facade.

On the initial stage determine the beacon lines for marking the facade - the lower horizontal line of the installation points of the brackets and the two extreme vertical lines along the facade of the building.

The extreme points of the horizontal line are determined using a level and marked with indelible paint. two extreme points, using a laser level and a tape measure, determine and mark with paint all the intermediate points for installing the brackets.

With the help of plumb lines lowered from the parapet of the building, vertical lines are determined at the extreme points of the horizontal line.

Using facade lifts, mark with indelible paint the installation points of the bearing and support brackets on the extreme vertical lines.

MAIN WORKS

3.6 When organizing the production of installation work, the area of ​​\u200b\u200bthe facade of the building is divided into vertical grips, within which work is performed by different parts of the installers from the first or second facade lifts (Fig.). The width of the vertical grip is equal to the length of the working deck of the facade lift cradle (4 m), and the length of the vertical grip is equal to the working height of the building. The first and second units of installers working on the 1st facade lift, alternating in shifts, carry out sequential installation work on the 1st, 3rd and 5th vertical grips. The third and fourth units of installers working on the 2nd facade lift, alternating in shifts, carry out sequential installation work on the 2nd and 4th vertical grips. The direction of work is from the basement of the building up to the parapet.

3.7 For the installation of a ventilated facade by one link of workers from two installers, a replaceable grip equal to 4 m 2 of the facade is determined.

3.8 Installation of a ventilated facade starts from the basement of the building on the 1st and 2nd vertical grips simultaneously. Within the vertical grip, installation is carried out in the following technological sequence:

Fastening sliding brackets to guide profiles;

Installation of ventilated facade cladding elements to the outer corner of the building.

3.9 Installation of the frame of the facade cladding of the plinth is carried out without using a facade lift from the ground (with a plinth height of up to 1 m). The parapet tide is mounted from the roof of the building at the final stage of each vertical grip.

3.10 The installation points of the bearing and support brackets on the vertical grip are marked using beacon points marked on the extreme horizontal and vertical lines (see), using a tape measure, a level and a dyeing cord.

When marking the anchoring points for the installation of bearing and supporting brackets for the subsequent vertical grip, beacons serve as the points of attachment of the bearing and supporting brackets of the previous vertical grip.

3.11 For fastening to the wall of the bearing and supporting brackets, holes are drilled at the marked points, the diameter and depth corresponding to the anchor dowels, which have been tested for strength for this type of wall fencing.

If a hole is drilled in the wrong place by mistake and it is required to drill a new one, then the latter must be at least one depth of the drilled hole from the wrong one. If this condition cannot be met, the method of fastening the brackets shown in Fig. four.

Holes are cleaned from drilling waste (dust) with compressed air.

Rice. 4. Mounting unit for supporting (supporting) brackets if it is impossible to attach them to the wall at the design drilling points

The dowel is inserted into the prepared hole and knocked out with a mounting hammer.

Thermal insulation pads are placed under the brackets to level the working surface and eliminate "cold bridges".

The brackets are fastened to the wall with screws using an electric drill with adjustable speed and appropriate screwing nozzles.

3.12 The device for thermal insulation and wind protection consists of the following operations:

Hanging on the wall through the slots for the brackets of the insulation boards;

Hanging on the heat-insulating plates of the panels of the wind-hydroprotective membrane with an overlap of 100 mm and their temporary fixing;

Drilling through the insulation and the wind and hydroprotective membrane of holes in the wall for dish-shaped dowels in full according to the project and installing the dowels.

The distance from the dowels to the edges of the heat-insulating plate must be at least 50 mm.

The installation of heat-insulating plates starts from the bottom row, which are installed on the starting perforated profile or plinth and mounted from the bottom up.

The plates are hung in a checkerboard pattern horizontally next to each other in such a way that there are no through gaps between the plates. Permissible size of an unfilled seam - 2 mm.

Additional heat-insulating plates must be securely fixed to the wall surface.

To install additional thermal insulation boards, they must be cut with a hand tool. Breaking the insulation boards is prohibited.

During installation, transportation and storage, thermal insulation boards must be protected from moisture, contamination and mechanical damage.

Before starting the installation of heat-insulating plates, the removable grip on which the work will be carried out must be protected from atmospheric moisture.

3.13 Adjusting carrier and support brackets are attached to the carrier and support brackets, respectively. The position of these brackets is adjusted in such a way as to ensure the vertical alignment of the deviation of the wall irregularities. The brackets are fixed with bolts with special stainless steel washers.

3.14 Fastening to the adjusting brackets of the vertical guide profiles is carried out in the following sequence. The profiles are installed in the grooves of the regulating bearing and support brackets. Then the profiles are fixed with rivets to the bearing brackets. In the supporting adjusting brackets, the profile is installed freely, which ensures its free vertical movement to compensate for temperature deformations.

In the vertical joints of two successive profiles, to compensate for thermal deformations, it is recommended to maintain a gap of 8 to 10 mm.

3.15 When adjoining to the plinth, the perforated flashing is fastened with a corner to the vertical guide profiles using blind rivets (Fig. ).

3.16 Installation of cladding panels starts from the bottom row and leads from the bottom up (Fig. ).

Sliding brackets (9) are installed on the vertical guide profiles (4). The upper sliding bracket is set to the design position (fixed with the set screw 10), and the lower one - to the intermediate one (9). The panel is put on the upper sliding brackets and by moving the lower sliding brackets it is installed “into the spacer”. The upper sliding brackets of the panel are additionally fixed with self-tapping screws from vertical shift. From the horizontal shift, the panels are also additionally attached to the supporting profile with rivets (11).

3.17 When installing cladding panels at the junction of vertical guides (bearing profiles) (Fig. ), two conditions must be observed: the top cladding panel must close the gap between the bearing profiles; the design value of the gap between the lower and upper facing panels must be exactly maintained. To fulfill the second condition, it is recommended to use a template made of a wooden square bar. The length of the bar is equal to the width of the cladding panel, and the edges are equal to the design value of the gap between the lower and upper cladding panels.
