The use of gutters and their varieties. Features of different types of gutters for the roof Types of gutters on the roof

One of essential elements properly equipped roofs are drainage systems. Such structures are of several types, and for their production is used various material. But any storm drain not only protects the basement and foundation of the house from flooding.

• Finding the required number of pipes is also not difficult. Multiply the number of risers by the height of the walls. The standard pipe length is 3 meters.
• Calculating fasteners is a little more difficult: the brackets should have a pitch of no more than 60 cm, and pipe clamps - 1.5–2 meters.
• The required number of additional elements, as connecting elbows, outer and internal corners, couplings and plugs, determines the complexity of the configuration of the roof and facade of the house.

Advice! Material such as fasteners: brackets or hooks for gutters, it is better to take with a small margin. Installation may be required additional fasteners on difficult roof areas, for example, to ensure the desired slope.

Installation of drainage systems

Let's take a closer look at the order in which the drainage system is installed for pitched roofs. First of all, a frontal board is installed under the roof overhang, on which a roof storm drain is installed. In this case, the following sequence must be observed:

• Water intake funnels are being installed at the corners of the roof of the house. Their fastening is carried out with ordinary self-tapping screws in the mounting ears.
• Then brackets or hooks are attached to install the gutters.
• The first bracket is installed at a distance of no more than 10 cm from the water intake funnel.
• Then the outer bracket is installed on the other edge of the roof. Its installation should be carried out as high as possible under the very overhang of the roof.
• A nylon thread is pulled between them to control the slope.
• Intermediate brackets are attached with a step between them of 40–50 cm.
• After mounting the brackets, the nylon thread that controls the slope is removed and the installation of the gutters begins.

Advice! It would be best if the material for the manufacture of gutters and brackets is the same. This greatly simplifies installation. drainage system.

• The gutters and brackets included in the kit have a tenon-groove system that allows you to securely fix the structure.
• Additional fixation of the gutters is made by latches, which are available on the connecting elements of the roof storm drain.
• Having installed the gutters, it is advisable to check the slope again. This is an important factor in high bandwidth storm sewer.

After that, you can proceed to the installation of vertical drainage pipes. They are fastened to the facade of the house using clamps with a long mounting pin. To connect the vertical and horizontal sections of the drainage system, mounting elbows and trimming of downpipes are used.

Advice! Sometimes, to ensure a more reliable connection of stormwater elements, silicone sealant is used. This material allows you to achieve complete sealing of all joints.

In conclusion, we note that the drainage system is an indispensable attribute of a properly designed country house. In addition to all the protective functions that an organized drainage system has, it allows you to collect rainwater for domestic needs. For example, watering a garden or vegetable garden.

The external drain from the roof is important system protect the building from rain and melting snow, because its purpose is to collect water from the roof slopes and drain it into storm sewer. In the article, it is considered what gutter systems are and according to what principles they are mounted on roofs.

Types of drainage systems

There are three main varieties in total:

unorganized external drain. In fact, this is a roof cornice that extends beyond the wall by at least half a meter.

Outer organized roof drain. This is a system that includes trays, they are also horizontal gutters, and vertical pipes installed in the form of risers.

Organized internal. This system is only used for flat roofs. We will discuss this variety in a separate section.

And now we will deal with the external drainage system.

Outdoor drainage system

As already mentioned, it includes: gutters located under the edge of the roofing, pipe risers. Both parts of the system are interconnected by funnels. In addition to these elements, the drain includes:

brackets, as fasteners for gutters;

clamps with which pipes are attached to the walls of the house;

couplings, which are used to connect gutters and pipes;

pipe bends at 90 and 45 0;

drain pipe branch, used at the very bottom of drains.

Gutter materials

Today, manufacturers offer two materials, of which gutter elements manufactured: galvanized steel (painted or coated polymer layer), plastic. Note that hardware They are more expensive, but will last longer on the roof. As for the technology of installation and assembly, both varieties do not differ from each other.

But plastic gutters they are not as noisy as metal ones, besides they are neutral to slightly aggressive environments. Today, manufacturers offer gutter systems made of PVC and a special variety of vinyl. The latter is the owner of high performance characteristics. Pipes and trays made from it do not crack in frost, which often happens with PVC. Therefore, they are recommended for use in northern regions countries.

It should be noted separately gutters made of copper. Expensive option with a long service life. Yes and by decorative qualities it is superior to plastic and galvanized, although the latter two are represented on the market by a huge color design. Unfortunately, copper products are rarely used in private housing construction - many cannot afford it.

How to correctly calculate the external drainage system

Basically it concerns the elements of the system. The number of gutters depends on the length of the roof eaves. For example, if gable roof 10 m long, then the length of the cornice is 20 m. Accordingly, the length of the purchased trays, in general, should be 20 m. And since the standard gutter length is 3 m, then the quantity is determined as follows: 20: 3 \u003d 6.6, rounded - there will be 7 pieces.

Pipes are a little different. Firstly, the length of the riser depends on the height of the wall of the building. Secondly, the number of pipes depends on how many risers will be installed on the roof. Here the ratio is:

if the length of the roof eaves is within 10 m, then mount one riser;

if greater than this value, then several risers.

But in the latter case, it is taken into account that the distance between the risers should not exceed 20 m. Knowing the height of the wall and the number of pipe risers, it is possible to determine the number of pipes on the basis that one pipe has a length of 3 m.

By the way, the number of risers determines the number of funnels and lower drain pipes. They are equal in quantitative terms. But there will be twice as many withdrawals.

On our website you can find the most . In the filters, you can set the desired direction, the presence of gas, water, electricity and other communications.

As for the brackets for the trays, their number is determined by the installation step of the fasteners, equal to 50-60 cm. But keep in mind that the first and last brackets are installed from the edge of the grooved structure at a distance of 30 cm. As for the clamps for pipe risers, the distance between them - 1.8-2.0 m. But if the wall height exceeds 20 m, then the installation step is reduced to 1.5 m.

These were calculations of the number of elements. But there are also overall parameters - this is the diameter of the pipes and the cross section of the tray. Since the standard size presented by the manufacturers corresponds to standard parameters pipe products, respectively, and the drainage capacity of the elements of the drain is different. There is a simple relation here more area the slope of the roof, the greater the ability of the gutter system should have. And it depends on the diameters of pipes and trays. Therefore, we offer the ratio of the slope area and the diameters of pipes and trays:

up to 30 m²– pipe diameter 80 mm, gutters diameter 100 mm;

30-50 m²- pipe 87 mm, tray 100-120;

50-125 - respectively 100 and 150 mm;

Over 125 m², pipe 110 mm, gutter 150-200 mm.

Gutter installation rules

The external drain is a gravity flow system, so the gutters are laid at an inclination of 2-3 mm per 1 m of the length of the flume route. This important circumstance is taken into account during the installation of brackets. This is done this way if, for example, two risers are installed on the wall at the corners of the building.

Determined middle of the cornice.

He received the mark at two different sides set aside 30 cm.

In these places mounted on a bracket at the highest point. The two fasteners must be at the same horizontal level.

For example, if the length of each part is 10 m, then incline grooved design determined according to the following scheme: for each meter, 2 mm, it turns out for 10 m 2 cm.

retreat from the edge of the corner of the house 30 cm and at this point a bracket is mounted, which is 2 cm lower than the one already installed.

Now between the two brackets pull a strong thread. It is at an angle of 2°.

Right on her install intermediate brackets in increments of 50-60 cm.

So install brackets either side of the middle of the roof eaves.

It remains to lay trays on top of the brackets. Today on the market you can buy gutters with a socket connection and with a socket. The first is simpler, fewer additional elements. The design of each gutter has a reduced diameter on one side, which fits tightly into the other side of the tray, where the diameter is standard. It is recommended to process the joints of two gutters silicone sealant to increase the tightness of the connection.

Plugs are installed from the edges of the trays. A funnel is mounted at the installation site of the pipe risers. By the way, external drain funnels are represented on the market by two constructive views: a standard funnel and a chute with a branch pipe that enters the riser pipe through a socket connection system.

Installation of risers

It is easier here, because the riser is set vertically. That is, it is necessary to lay a vertical line from the funnel to the ground on the wall using a plumb line. Then mark the installation of clamps, which are immediately attached to the wall with anchors or self-tapping screws on plastic dowels.

There are several points to pay attention to:

Bottom clamp installed at the junction drain with pipe.

The lower end of the drain pipe must be above ground level at a distance of 25 cm. This is exactly what the marking reference point is.

Now about how to connect the pipe riser correctly with a drain funnel for outdoor drains. Since the length of the eaves in different roofs has a different value, the segment from the funnel to the riser will also be different. First of all, two taps are indispensable here. Secondly, if the length of the cornice is large, then a piece of pipe from the drain will have to be installed between the outlets.

In fact, the installation process is not very complicated, if you strictly follow the points of the information provided above. Masters in one working day calmly mount the drainage system of one house. That is, it takes a little time.

All about domestic drainage

So, let's move on to the topic - the internal drain flat roof. It is called so because the vertical pipe along which it moves from the roof slope rainwater down into the sewer, located inside the building. And on top of the roof itself, a funnel of a special design is installed. She's covered strainer so that debris does not get into the drainpipe.

There are some requirements for the internal drainage:

for every 150-200 m² of slope area establish one funnel;

towards the funnel slope stack at an inclination of at least 4°;

diameter pipes are selected based on - 1-1.5 cm² of its cross section per 1 m² of roof area;

soft roofing on the sides of the funnel;

riser should be located in a heated room;

On a note! The riser is connected to a drain pipe, which is laid at a slope of 2-5 ° towards the storm sewer under the house, and the pipe crashes into it;

it is forbidden install a funnel near the wall of the building.

The construction of the internal drainage system begins before the foundation is laid. That is, they lay a drain pipe. If the foundation is already filled, then a hole is made in it with a perforator to the diameter of this pipe, where the latter is pushed. Today, it is not uncommon for a drain horizontal section of a drainage system to be laid under the floor of a house on the first floor or in basement under the ceiling. This greatly simplifies the installation process. But here, in any case, you have to make a hole in the foundation. In order not to do this in the foundation structure at the stage of its construction, it is better to leave a hole by inserting a pipe segment of a larger diameter during pouring.

The riser is laid inside the office premises. Therefore, the place of its passage through the ceilings is determined in advance in the project, in which through holes are left or made. Subsequently, after the installation of the drain, they are sealed and insulated. The main task of the manufacturer of works is to carry out installation with complete sealing of the joints. Therefore, the joints of the pipes with each other, as well as with fittings, must be treated with silicone sealant. It is required to leave at least one revision in the riser. This is in case of clogging of the drain pipe.

The most important stage in the construction of an internal drain is the installation of a water intake funnel. Here, one hundred percent sealing is required so that atmospheric precipitation does not penetrate under the roofing material.

Conclusion on the topic

So we tried to give full information on the external drainage system and touched on a little the topic of internal drainage. In fact, this system is simple, because it consists of only two sections, and its equipment is not wide. The main thing is to accurately connect the parts of the system to each other. Although this is not difficult to do, because the manufacturers have taken care of the maximum ease of assembly.

. Roof- this is the upper enclosing structure of the building, which simultaneously performs load-bearing, waterproofing, and with non-attic (combined) roofs and warm attics, and also heat-insulating functions.
The roof is one of the main elements of the building, protecting it from external influences: rain, snow, frost, solar radiation, dust, harmful substances etc. It must withstand wind and snow loads and comply with fire safety standards, and in addition, perform decorative functions.
Roof- this is the upper element of the roof (covering), which protects the building from the penetration of atmospheric precipitation.
Attic- this is the space between the surface of the coating (roof), the outer walls and the ceiling of the upper floor. It reliably protects the house from the cold, provides ventilation and airing of the structural elements of the roof. From a structural point of view, the attic significantly increases the reliability and durability of the roof, however, it increases the cost of the building compared to a house with an attic.
Attic- floor in the attic space, the facade of which is completely or partially formed by the surface (surfaces) of an inclined or sloping roof, while the line of intersection of the roof plane and the facade should be at a height of no more than 1.5 m from the floor level attic floor. The internal space of the house is used to the maximum, why the cost buildings are significantly reduced.
Roofs suit attic and non-attic. In non-attic roofs, the latter simultaneously performs the functions of an attic floor; in this case, the roof is called a covering, or combined roof.
The roof is insulated or cold. Attic roofs for most buildings are cold. cold roof protects the building only from precipitation; thermal protection of the premises of the upper floor is provided (if necessary) attic floor. Non-attic roofs can be cold (over unheated buildings) and warm (over heated buildings).

BY THE SHAPE OF THE ROOF THEY ARE DIVIDED INTO SLATED AND FLAT.
1. Flat roof- a roof with a slope of less than 2.5%. May be exploitable.
2. Pitched roof- a roof with a slope of more than 2.5%.
Pitched roofs are divided into: resting on two outer walls of different heights. Most often it is used on auxiliary buildings, structures of a simple design, industrial or warehouse buildings. The slope of the roof is turned to the windward side, thereby protecting the building from wind, rain and snow. They are the most economical and convenient and allow you to make the most of inner space buildings can serve as a ceiling in outbuildings (garages, sheds, bathhouses, etc.) that do not require its strict horizontality.

gable resting on two outer walls of equal height. They consist of two slopes directed in opposite directions. The triangular end walls formed with this form are called tongs and gables. It is the most common classic roof construction. There are options for roofs with hanging roof trusses or with sloped rafters. The numerous options of this type include roofs with a uniform or uneven angle of inclination or the size of the overhang.

hip roof- a hipped roof with triangular slopes (hips) from the ridge to the cornice on the end sides. If the hip does not reach the eaves, the roof is called half-hip. Character traits- the presence of dormer windows. Sometimes four-pitched roofs are made in the form of half-hip roofs. In this case, the side slopes (half-hips) are cut off and have a shorter length along the slope than the main slopes. Half-hipped roofs are used to protect the pediment from adverse external influences, it is best able to withstand wind loads, but it is very laborious, and its construction requires certain professional skills.

Tent, four slopes of which are made in the form of identical triangles converging at one point; A tent, a tent covering is the completion of centric buildings (temples, bell towers, towers) in the form of a high tetrahedral, octahedral or polyhedral pyramid. Widespread in Russian stone architecture since the 16th century. . In religious buildings, the tent was usually crowned with an onion dome, in civil and military buildings - a watchtower, a weather vane.

Broken lines (attic), gable, each plane of which is two rectangles connected to each other at an obtuse angle. If it is necessary to use an attic room for drying clothes, storing household utensils or installing an attic, the roof of a residential building is made gable or broken.
ROOF ELEMENTS
1. load-bearing structure, consisting of wooden beams, rafters or prefabricated trusses, consisting of upper and lower chords and a lattice of bevels and struts enclosed between them;
2. foundations for roofing;
3. hydro- and heat-insulating layer;
4. roof.
Rafter. The supporting structures of attic low-rise roofs are rafters, which are layered and hanging. Roofs with layered rafters are arranged in houses with supporting walls. The span between the supports can reach 4.5 m. When spanning from 5 to 6 m, struts are placed under the rafters. The roof structure is selected taking into account the slope of the roof, the length of the span to be covered, the section of the rafters and battens, the type roofing material and the amount of snow cover.
Laminated rafters:
Laminated rafters are simpler in design and economical, however, their use requires the presence of internal walls or load-bearing partitions. These rafters consist of a pair of individual slanted rafter legs, resting with their lower end on the top of the walls, and with their upper ends connected to each other, on a run supported by racks. Racks are supported by load-bearing internal walls or partitions. Rafter legs are made from logs 13-20 cm thick, from plates 15/2-20/2 cm or boards with a thickness of at least 5 cm. The rafters are placed at a distance of 1 to 1.5 m from each other. To reduce the deflection of the rafter legs, if they are not thick enough, struts are placed from logs 13-15 cm thick, beams or paired boards, and in some cases (with asymmetrical internal supports) - crossbars (increased puffs) from plates with a cross section of at least 13X2 cm, as well as from bars or paired boards.
Hanging rafters:
are used when the roof span is 7-12 m and in the absence of intermediate supports, as well as in houses with walls made of raw materials. The simplest hanging rafters consist of rafter legs (upper belt) and puffs (lower belt), interconnected by cuttings, forgings and nails. To prevent deflections of the rafter legs (if they are not thick enough), a crossbar is inserted between them. With spans of more than 6 m, hanging rafters are made with a stand (headstock) in the middle, to which a puff is suspended on a steel clamp. Hanging rafters are made from logs, beams or boards. Under-rafter beds (Mauerlats), beds under racks and other parts of rafters in contact with walls made of stone and raw materials are isolated from them by means of pitching or laying roofing. For the Mauerlat, which is arranged in order to evenly distribute the weight from the roof along the entire wall, logs with a thickness of at least 18 cm are selected. chimneys distance from rafter legs to smoke channel must be at least 40 cm.
Roof base
from piece or rolled materials, it can be made in the form of a crate or a continuous flooring. In the first case, for its manufacture are used wooden blocks, in the second - wooden bars and boards.
1. solid flooring is done when asbestos-cement tiles are used as a coating or roll material. Under the tiles, the flooring boards are laid out with a small gap (no more than 10 mm) in one layer, under the rolled material - in two layers: working and protective.
Narrow boards of the protective layer should be at an angle of 45 degrees to the working one. An anti-wind gasket made of roofing material is placed between the decks.
2. crate used when the roofing is made of corrugated asbestos-cement sheets(slate), sheet steel, tiles or wood.
In the manufacture of the base, two basic requirements must be observed: all its elements must be tightly fixed to load-bearing structures, and their joints above the rafters are spaced apart. The specified distance between boards or bars - purlins - must be strictly observed over the entire surface of the base. The widest of them must be placed under the joints of the roofing material, as well as at the ridge and cornice, and the thickest (15-35 mm thicker than others) at the cornice. The width of the base under the groove should be at least 750-800 mm, and under the cornice overhang with wall gutters - equal to the width of the overhang. In the ridges and on the edges of the roof, wooden bars are installed on the edge.

Drainage systems. The drainage of water from the roofs of attic roofs (rain and melt) is unorganized and organized. With unorganized drainage, water flows from the roof along its entire length. Such drainage is allowed only in low-rise buildings, provided that the flowing water does not fall on the sidewalks. With organized drainage - water flowing from the roof is diverted through the gutters to the external drainpipes. There are three types of gutters: wall-mounted, suspended and remote (Fig. 1).

Drainage system from pitched roofs

Rice. 1. Drainage device from pitched roofs:

a - wall gutter; b - reinforced concrete cornice-chute; c - drain cornice with a hanging gutter (1 - roof; 2 - wall gutter; 3 - hook; 4 - funnel; 5 - downpipe; 6 - hanging gutter; 7 - pasting waterproofing; 8 - roofing steel; 9 - capercaillie; 10 - handrail post with a strut; 11 - enclosing rods, or strips); g - funnel of the internal drain (1 - funnel bowl; 2 - clamping ring; 3 - cover; 4 - fixing screw; 5 - fiberglass; 6 - asbestos cement pipe; 7 - insulation; 8 - elastic gasket; 9 - flange; 10 - clamping screw).

Drain pipes are made from roofing steel 0.5 ... 0.6 mm thick and consist of an upper funnel and a pipe made up of separate links and having kinks at the top of the funnel and at the bottom at the mark. Pipes are made with a diameter of 105, 140 and 215 mm. The diameter of the upper part of the funnel should be 2 ... 2.5 times the diameter of the pipe. The downpipes are fastened to the walls with the help of grips located at a height of 1 ... 1.5 m and firmly embedded in the walls. With internal drains on the roof, special water intake funnels are installed, connected to cast-iron risers passing inside the building and diverting water into an underground storm network or sewer.

The cast-iron funnel of the internal drain consists of a funnel bowl, a clamping ring, a cap or a roof, a fixing device (see Fig. 1). Water intake funnels are installed in the valleys. Pipes located inside the building divert atmospheric water into the sewer. The distance between the funnels depends on the length of the slope. The roof area per one funnel should not exceed 800 ... 1200 m2. The necessary longitudinal slopes for water flow to the funnels in the valleys are created due to the variable thickness of the layer of lightweight concrete laid in them. The longitudinal slope must be at least 1°. Inlet funnels internal drains are made from cast iron. The funnel consists of three main parts: a branch pipe that enters the upper end and is embedded in the roof structure, a body with holes for receiving water flowing from the roof, and a lid or cap with holes. Each funnel is connected to a pipe (riser) with a diameter of at least 100 mm. In the places where the funnel is installed in the coating, holes of 400x400 mm in size are provided, into which a bowl-shaped cast iron pallet with a hole for the funnel nozzle. When installing the pipe in the pan, the sections between its walls and the funnel are poured with hot bituminous mastic, fiberglass or burlap impregnated with bitumen, and the edges of the roof are brought into it. The body of the funnel is installed in the pipe on top of the roof and is also filled with bitumen in the lower part.

Outdoor organized drain

Outdoor organized drain is a drainage system that is arranged outside the house. External drainage systems are used to drain water from pitched roofs (with a slope of more than 15%). This drainage system consists of gutters with a longitudinal slope of at least 2% and external downspouts. The system works like this:

Water from the roof slopes enters the gutters, from there - into the intake funnels, which are located at eaves overhangs at a distance of 12-20 m from each other, and then discharged through drainpipes, which are fixed on the outer walls of the building, in drainage well or storm sewer (a large barrel may be an option).

Advantages of an outdoor organized drain:

Provides protection of the roof, walls of the house and the foundation from the effects of precipitation

Disadvantages of outdoor drainage:

Snow rolling off the roof can tear down gutters from the fixtures

In this case, the gutter is installed so that its outer edge is not higher than the plane that continues the surface of the roof slope. In this case, the middle of the gutter should be located on a vertical line directly under the edge of the eaves drain so that all the water flows into the gutter - see fig. :

Gutter installation

The system can be deformed from the action of the wind, from mechanical shocks.

Without heating in winter, the entire drainage system can freeze and it can “break”.

The external drainage system from the roof consists of:

External roof drainage system

water intake funnel,

Cornice gutters, they are installed along the cornice overhang.

eaves gutter

Parapet gutters are found in old houses, they collect water in a gutter located between two parapet walls (such architectural solutions are quite rare in modern private construction). The parapet gutter is constructive element roofs. The gutter is made of metal, or the recess where water comes from the roofs is covered bituminous material. Water is supplied to the weir. (rice).

parapet gutter

Grooved gutters direct water into eaves or parapet gutters. They are a type of plums at the junctions of the roof slopes.

Gutter gutter

Work drain system roofing would be impossible without the use of special guides. Gutters and pipes are required to control waste water and pointing her in the right direction.

Types and design

A gutter is necessary for any roofing system, because without it, rain or melt water will roll directly under the foundation of the house, thereby deteriorating its performance properties.

Photo - Design

These building elements can be classified according to the material from which they are made, or design. Let's consider the first type. The most common now are gutters made of PVC (plastic) and steel (tin, alloy), although drains from cement, wood and even natural stone were previously actively used.

1. Metal drainage systems are the most popular in this moment. They provide the maximum level of protection for the house from flooding the foundation, in addition, they are rigid and durable. The service life of such guides is more than 30 years, they are indestructible mechanical influences and resistant to aggressive external environment. But keep in mind that steel has a fairly large weight, which will be inappropriate if the building is on a pillar or pile foundation. In addition to classic steel gutters, copper gutters are now being installed. They do not require galvanizing, since copper itself does not rust, but at the same time they have significantly more weight than alloy steel options;
2. Plastic gutters perfectly installed on houses with any foundation. They do not corrode and are known for their lightness. Their fastening can be easily done by hand. The disadvantages include a strong roar during the fall of drops on plastic. Also, we must not forget that when the water in the drain freezes. The pipe cracks, which is a negative factor for any drain. To protect them from the effects of acid rain, manufacturers make drains with a polymer coating;
3. Wooden gutters have become obsolete due to the fact that the material of manufacture does not tolerate the effects of water. Of course, some owners still use them to create an exotic exterior, but they are extremely impractical. Advantages include beautiful appearance and ecology. Disadvantages: the appearance of mold and fungi, rapid destruction (within 5–7 years), high cost, difficulty in maintenance;
4. Concrete gutter can often be found in high-rise buildings, but it is mainly used by the sidewalk drainage system. The cement has a high specific gravity, therefore not used for private buildings. It does not give in to corrosion, but instead of it, the destruction of the stone occurs under the influence of water.
