Online calculator for calculating building blocks. How to find the volume in cubic meters Online wall cubic capacity calculator

Our visitors often ask the question: how to calculate required amount bricks and wall blocks to build a house? Especially for private developers, we posted an example of calculating the number of bricks for construction two-story house size 10 by 10 meters (200 m2) with a ceiling height of 3 m (simplified version).

1. Determining the length of the outer walls: 10+10+10+10=40 m.
2. Determining the area of ​​the outer walls. To do this, the resulting length of the outer walls must be multiplied by the height of the house, i.e. 40*6=240 m2
3. Brick laying should be chosen. For example, let's take a laying of 2.5 bricks, while laying of 2 bricks will be made of double brick and one row (in half a brick) - from a single front.
4. In order to find the required number of bricks, you need to multiply the area of ​​\u200b\u200bthe outer walls by the number of bricks in 1m2 of masonry (see table), 240 * 104 \u003d 24960 pieces of double brick and 240 * 51 \u003d 12240 pieces of front single brick.

Thus, for the construction of the house chosen by us, we need 24960 pcs. double stone and 12240 pcs. facing brick.

It should be noted that window and door openings were not taken into account in the calculation. However, even such a calculation allows you to determine the required amount of bricks, which in turn will help draw up a budget and estimate for construction. Do not forget to count the bricks on the internal partitions of the house. face brick. We recommend buying facing brick in one batch at once, this will avoid the difference in brick shades and order 15-20% more than the calculated quantity. Below are tables for bricks and wall blocks. (calculation wall materials, calculation of bricks per house)

Comparative characteristics

Cellular concrete, foam concrete, expanded clay concrete, ceramic brick.

when buying bricks, reinforced concrete products and wall blocks (blocks made of cellular concrete) require accompanying documents: certificate or passport for products. In the absence of these documents, on a brick or other construction material better not be tempted.

If you do not want to "drown the street", do not make the outer walls less than 2.5 bricks (that is, 64 cm) thick, otherwise the heat will leave the house. Otherwise, you can use well masonry with an attachment mineral plates based on basalt (ISOBOX) this will reduce the load on the foundation without losing thermal insulation properties walls.

When buying imported bricks, please note that European standards do not always coincide with domestic ones in size, frost resistance, strength indicators. Keep this in mind when using imported and Russian bricks together. It should also be taken into account that the thickness of domestic reinforced concrete elements(lintels, floor slabs) is a multiple of the height of domestic bricks.

Recently, questions have been received about the construction of aerated concrete, questions on the projects of purchased houses, recalculation of one size to another, etc. from visitors to our site DCI GROUP.
How to calculate the cubature of a gas block for the construction of a cottage, if I only have a total square of walls of 234 m 2?

Everything is not difficult at all! There are two options for converting the quadrature of walls into the cubic capacity of aerated concrete products.

Peter, Chelyabinsk asks a question:

Hello. I'm building in the summer country house near the city. I decided to make it out of brick. Due to the difficult economic situation and constantly rising prices, I decided to purchase bricks in advance. Therefore, I would like you to help me answer the question of how to calculate cubic capacity brickwork. I have not yet decided on the thickness of the wall, everything will depend on my financial resources for the purchase of the required amount of bricks. Therefore, I would like to know how to calculate the number of bricks for walls different thickness. And how difficult is it, can I cope with the calculations myself? Thanks in advance for your reply!

The expert answers:

The volume of the required number of bricks depends on the chosen masonry method.

Hello! This is very good decision- to purchase the main building material in advance, because no one knows whether the prices for a brick block will skyrocket this year or remain the same. The economy has been unpredictable lately.

There are few formulas that allow you to answer the question of how to calculate the cubic capacity of brickwork, and they are quite simple. To calculate, you absolutely do not need to have any additional knowledge in the field of mathematics, it will be enough to have the basic foundations. Even a schoolboy can cope with calculations.

In order for you to correctly calculate the cost of the purchase, you need to take into account not only the cost of the building material itself, but also its delivery and unloading.

The width of the wall directly depends on the blocks laid in it. The standard length is 25 cm. If the building is half a block, this means that the width of the wall is 12 cm. 1.5 bricks is 38 cm (12 cm + 25 cm + 1 cm per seam). 2 - 51 cm; 2.5 - 64 cm.

Thickness standard in middle lane RF is 1.5-2.5 bricks. To determine the required amount of basic building material, you need to calculate the cubic meters of the whole house. The first step is to find out the length of the perimeter of the building, you can do this with a tape measure or see its length in the project, if you have one. Measure along and across, if the windows are different, it will complicate things a bit. Multiplying these parameters, get the area of ​​the windows. Do the same for all doorways.

After the cubic meters of the house openings are calculated, they must be subtracted from the total cubic meters of the house.

When calculating, keep in mind that the length and width of all bricks are the same, but the height can be different: 6.5 cm; 8.8 cm and 13.8 cm.

Thus, for 1 sq.m of a single brick wall, 50 of them will be required. From one and a half - 39 pcs. if from a double - 26 pcs.

To get the required amount of material, you need to multiply the area by the number of bricks spent per 1 sq.m. To get the final result, multiply by 2 if the wall is 1 brick; by 3 if in 1.5; by 4 if in 2.

Now you know how to calculate the cubic capacity of brickwork yourself. In any case, all the calculations that you make will be approximate, the exact amount of material cannot be calculated. But there is nothing to worry about, because you can always buy the missing amount of building materials. Good luck with your construction!

Before purchasing any building material, it is necessary to determine as accurately as possible right amount, otherwise you can lose some amount due to the remaining surplus or the need for additional purchases, as well as the unaccounted for the possibility of fraud by unscrupulous sellers. Timber, logs, boards and similar wood products, as you know, are sold in cubic meters, which means that you need to know in all subtleties the calculations for determining the volume of these materials, as well as converting the required number of pieces into cubes and back. And in the case of purchasing timber for building a house, when calculating the required amount of this building material, it is also necessary to take into account the design and features of the future building.

Basic calculations - volume determination and conversion from pieces to cubes and vice versa

Calculating the cubic capacity of timber, boards and similar lumber is very simple. To do this, you need to know the thickness, width (height) and length of the product. And, as you know from a school textbook on geometry, you need to multiply these dimensions:

V = T ∙ H ∙ L, where

V is the volume of timber, m 3;

T is the thickness;

H - width;

L is the length.

Before calculating, dimensions should be given in one unit of measurement: mm, cm or m. It is better in meters, so that later you do not have to convert from mm 3 or cm 3 to m 3.

Beam size chart

For example, let's calculate the cubic capacity of a bar 150x200. These dimensions, as you know, are indicated in mm. That is, the thickness of the product is 0.15 m, and the width is 0.2 m. The standard length of timber and boards is 6 m (sometimes also indicated in mm - 6000). Or maybe another. But for example, let's take exactly 6 m. Then the volume of this lumber:

0.15 ∙ 0.2 ∙ 6 \u003d 0.18 m 3.

Now you can convert the required amount (in pieces) of this product into cubes. Let's say you need 49 pieces:

0.18 ∙ 49 \u003d 8.82 m 3.

Knowing the volume of one product, you can also calculate the cube of the timber, that is, determine how many of its units (pieces) are in 1 m 3. To do this, you need to divide 1 cube by the cubic capacity of one product already calculated or taken from the reference tables (in this example, 0.18 m 3):

1 / 0.18 \u003d 5.55555 ... pcs.

In the same way, the amount of this type of timber is calculated for any volume.

The nuances of calculations - how not to make mistakes and not let yourself be deceived

As follows from the above methodology and calculation examples, it is very easy to calculate the required volume of timber in pieces or cubic meters. However, it must always be remembered that in 1 cubic meter there is not an integer number of these products. For the example given in the example with dimensions of 150x200 and a length of 6 m - 5.55555 ... pcs. Unscrupulous, most often retailers of timber cleverly take advantage of this.

For example, you need 1 cube of this material from the example. The seller, of course, releases 5 products, but takes the amount as for a whole cube. The overpayment will be the cost of half a bar.

And let's say that the same 49 bars from the example are needed to build a house. And if the seller considers according to the following scheme, then you will have to significantly overpay for the timber received:

• 1 cube - 5 products 150x200 6 m long;
• 49/5 = 9.8 cubes payable.

This is a divorce the purest water for 5 units of timber. They are superfluous and not needed, however, they will be paid, but not received. Above, in the calculation examples, the data of 49 products have already been translated into cubes - this is 8.82 m 3. That is, a "particularly enterprising" seller will deceive an inattentive buyer by:

9.8 - 8.82 \u003d 0.98 m 3 timber,

which is 0.98 / 0.18 \u003d 5.44444 ... pcs. this lumber (0.18 - the volume of one product calculated above).

Therefore, it would be most correct to calculate in advance exactly the number of units (pieces) of material, and only then, using these data and the dimensions of the timber or board, calculate their actual cubic capacity.

That is, in the case of purchasing one cubic meter in the above example, you must first decide how many bars you really need to take - 5 or 6. And then we consider their cubic capacity:

0.15 ∙ 0.2 ∙ 6 ∙ 5 (or 6 pcs.) \u003d 0.9 (or 1.08) m 3.

And for 49 units of this timber:

0.15 ∙ 0.2 ∙ 6 ∙ 49 \u003d 8.82 m 3.

Then you will have to pay exactly for these 0.9 (1.08) or 8.82 cubic meters, having received exactly 5 (6) or 49 products. Moreover, both the quantity in pieces and the volume in m 3 must be indicated in the invoice for the timber sold by the seller.

Other features of calculating the cubature of lumber

Another one important feature, which you should know for the correct calculation of the cubic capacity of the timber or boards when they are purchased. The actual length of lumber usually always slightly exceeds the standard or declared by the manufacturer of this product. So, instead of 6 m, the average length of the considered timber, as a rule, is 6.05 m. This is due to the fact that the ends of the lumber are not processed after it has been cut, because of which they may turn out to be uneven, go at angles, and be different or simply be dirty. Of course, these 5 cm do not need to be paid. But some cunning sellers, although quite rarely, still try to take into account even this when calculating cubic meters, which is pure deception.

And regarding the calculations for grooved and profiled timber. The presence of spikes, grooves, and other protruding or turned places should not be embarrassing. The calculation of the cubic capacity of such materials is no different from determining the volume of ordinary products that are even on all sides. For grooved and profiled lumber, the rule applies that only the main part (working width) of the product is measured and taken into account, and all structurally necessary and / or decorative elements are not included in the calculations. This provision applies to absolutely all types of timber.

Purchase of large volumes of materials - calculation of storage and dense cubic meters

When to Purchase a large number of timber, their cubic capacity is calculated somewhat differently than discussed above. For example, a timber and a board are needed for the construction of an impressive spacious house, as well as various other outbuildings near it. At the same time, the necessary lumber, for sure, will be different sizes in cross section and length. To measure and calculate each type of required material with similar purchase volumes is an occupation that can take more than one day.

For such cases, there is a specific calculation method. It is based on two important concepts:

1. 1. Dense cubic meter of wood. This is the name of the volume occupied only by wood and not having voids in it, as well as gaps. It is determined by measuring individual timber pieces, and then subsequent calculation of their total cubic capacity.
2. 2. Folding cubic meter. This is the name of the volume occupied by the most densely stacked lumber in a stack and having voids, as well as gaps between individual wood products. It is determined by measuring the stack, and then multiplying the dimensions of the latter. Moreover, in such a package, the main amount of material should have approximately the same length, and the remaining products may be shorter, but not longer. It is allowed to have short sawn timber in piles, which should be tightly stacked one after another.

In order to quickly calculate the large volume of required purchased lumber, which is already prepared and stored in the form of a stack, the latter is first measured, and then its cubic capacity is calculated. This will calculate the folding cubature. Then its value must be multiplied by a special conversion factor. The result is the volume of only wood ( dense cubic meter), that is, exactly those materials that are bought and will be paid for.

The value of the conversion factor is regulated by a number of standards for lumber: GOST 6782.2-75, 6782.1-75, 6564-84, OST 13-24-86 and others. For timber and boards, depending on their moisture content and the type of wood from which they are made, it is in the range of 0.74–0.82.

We consider the required cubic capacity of timber for building a house

• Height external walls measured from the foundation level. Let's denote it as H.
• The height of the internal partition walls, if any, and should be made of timber.
• The length of the outer and internal walls.
• The number and length of the bars used in rafter system, as floor beams and, as well as in its other structures - if it is provided for by the project.

Then we select the thickness of the material for each of the above structural elements. For outdoor and indoor bearing walls depending on the purpose of the house being built and the region where it is being built. For non-bearing partitions - at your own discretion. The plinth (lowest) crown of the outer walls is usually slightly thicker than the rest of the timber for them. For other elements of the structure, the thickness of the material is selected based on the conditions of its operation, as well as the required strength of the structures in which it is used. In a well-designed project, by the way, the thickness of the timber used for the walls, the basement crown, and other building structures should already be indicated.

Now only pure arithmetic remains. First, we calculate the perimeter of the house - we add up the length of all its external wall structures. For a simple rectangular or square structure, you just need to add up its width and length, and multiply the resulting value by 2. Then we calculate the cubature of the base crown:

V C = T C ∙ Z C ∙ I, where

V C - total cubic capacity of basement lumber, m 3;

T C - thickness of the basement, m;

Z C - its width (height), m;

I - the perimeter of the outer walls, m.

Calculate the remaining height of the outer walls, m:

h \u003d H - Z Ts, where

H - total height, m.

We calculate the area of ​​​​external wall structures without a basement crown, m 2:

If the thickness of the material of the basement crown is the same as that of the entire wall, then the area of ​​\u200b\u200bthe latter, m 2:

We calculate the area of ​​\u200b\u200bthe inner walls, the thickness of the lumber in which is the same as that of the outer ones, m 2:

S В1 = H В ∙ L В1 , where

H B - the height of the internal walls, m;

L B1 - the total (total) length of the internal walls, the material thickness of which is the same as that of the external ones, m.

We calculate the area of ​​\u200b\u200bthe internal walls, the thickness of the timber in which is different, m 2:

S B2 = H B ∙ L B2 , where

L B2 - the total length of the internal walls, the material thickness of which is different, m.

We calculate the cubature of the main lumber - for external walls and internal partitions from the same timber, m 3:

V S = (S Н + S В1) ∙ Z S , where

Z S - selected thickness of the product, m.

We determine the volume of material for internal partitions from another timber, m 3:

V B = S B2 ∙ Z B, where

Z B - selected material thickness for these partitions, m.

The results obtained (V C, V S and V B) are divided by the length of the purchased lumber and its selected width (height). Get the amount of material in pieces. We round this value to an integer value, and then we recalculate V Ts, V S and V V, as described in the second chapter.

To save on lumber, you should calculate the total areas of window, door and other openings for the corresponding walls. Then their values ​​\u200b\u200bshould be subtracted from S H, S B1 and S B2, respectively. After that, we calculate V S and V B using the same formulas. Then we increase the obtained values ​​​​by 10-20% - so that there is a margin just in case.

The cubic capacity of the timber for the rest of the elements of the house in which it is used is calculated even more simply. Its total length is calculated, which we multiply by the thickness and width selected for the material.

In our design organization, you can order the calculation of the volume of the room on the basis of a technological or design assignment.

This page provides the simplest online calculator for calculating the volume of a room. With this one-click calculator, you can calculate the volume of a room if you know the length, width and height.

A square meter is a unit of area, equal to the area a square with a side length of 1 meter. A cubic meter is a unit of volume, equal to the volume of a cube with ribs of 1 meter. Thus, these units are used to measure various properties of matter, therefore, from the point of view of physics, it is not entirely correct to talk about translating one unit of measurement into another.

However, in practice, there are often situations when it is necessary to convert dissimilar units of measurement (for example, a square meter to a cubic meter and vice versa).

Converting square meters to cubic

Most often, such a conversion is useful when calculating the amount of building materials, since some of them are sold in cubic meters, and are intended for arranging various surfaces which are conveniently measured in square meters. In order to convert square meters to cubic meters, in addition to the length and width of the product, you need to know its thickness. Product volume is calculated by the formula V=a*b*c, where

• a,b and c - length, width and height in meters.

For example, you need to sheathe a room with clapboard.

How to calculate the volume in m3?

The total area of ​​the walls is 200 square meters. The lining is sold in cubic meters. The lining thickness is 1 cm. In order to calculate the volume of building materials, the following calculations must be made:

• Now you need to multiply the area of ​​\u200b\u200bthe walls by the thickness of the lining in meters: 200 * 0.01 \u003d 2 cubic meters.

Thus, in order to sheathe 200 meters square walls you will need 2 meters of cubic lining.

Convert cubic meters to square meters

In some cases, it may be necessary to convert cubic meters to square meters - that is, to measure how much square meters material is contained in one cubic meter. To do this, you need to know the volume and thickness (height) of the material and make calculations using the formula: S = V / a, where:

• S - area in square meters;
• V - volume in cubic meters;
• a - thickness (height) of the material.

Thus, if you need to determine what area can be sheathed with 1 cubic meter of lining 1 cm thick, you need:

• Convert the thickness of the lining in centimeters to meters: 1/100 \u003d 0.01 meters;
• The volume of lining in cubic meters divided by the resulting thickness in meters: 1 m3 / 0.01m = 100 m2.

Thus, with a clapboard, the volume of which is 1 cubic meter, it is possible to sheathe walls with an area of ​​100 square meters.

In order for these calculations not to seem so complicated, it is enough to visualize the concepts of a cubic meter and a square meter. So, to imagine 1 cubic meter, you need to mentally draw a cube, the sides of which are equal to 1 meter.

To imagine how many square meters are contained in one cubic, you can divide the vertical plane of the cube into conditional strips, the width of which is equal to the thickness of the material being represented. The number of such bands will be equal to the area of ​​the material.

Volume is a geometric term that allows you to measure the quantitative characteristics of residential and non-residential space.

It is possible to determine the volume of a room, having information about its linear dimensions and shape characteristics. Volume is very closely intertwined with capacity characteristics. Surely everyone is familiar with such terms as the internal volume of a vessel or any container.

The volume unit is classified according to worldwide standards. There is a special measurement system - SI, according to which a cubic meter, liter or centimeter is a metric unit of volume.

Any room, be it a living room or production room- has its own characteristics of volume. If we consider any room in terms of geometry, then the room is comparable to a parallelepiped. This is a hexagonal figure, in the case of a room, its edges are the walls, floor and ceiling. Each side of the room is a rectangle. As is known from geometry, there is a formula for finding the volume of a rectangular parallelepiped. The volume of this figure is calculated by multiplying the three main dimensions of the parallelepiped - the length, width and height of the faces. You can also calculate the volume of a room using a simpler formula - the floor area is multiplied by the height of the room.

How to find out the volume of a room

So, how do you calculate the volume of a particular room? First, we measure the length of the wall, the longest in the room. Then we determine the length of the shortest wall in the room. All these measurements are carried out at the floor level, along the line of the baseboards. When measuring, the tape measure must be level. The time has come to measure the height of the ceiling. To do this, you need to hold a tape measure from floor to ceiling in one of the corners of the room.

All measurements must be recorded to the nearest tenth. After that, you can proceed directly to the calculation of the volume of the room. We take the length big wall, multiply it by the length of the smallest wall, then multiply the result by the height of the room. As a result, we get the necessary numbers - the volume of the room.

It may be necessary to calculate the volume of a room in the most different situations. So, you need to know the volume of the room when installing a sectional heating radiator. The number of sections in it directly depends on the volume of the room. If you are installing an air conditioner, you also need to know the volumes of the room, since a separate air conditioner is only designed for a specific volume of the room.

Complex room volume

In the case when the room has an irregular shape, you need to start again from the figure of a parallelepiped. In this case, the room will be represented by a large and small volumetric body. So, the volume must be measured separately for a large parallelepiped, and then for a small one. After that, the two volumes are added together. It happens that the structure of the room is completely non-standard, there may be arches and niches of a semicircular formation. In this case, the volumes must be calculated using a different formula - the volume of the cylinder. The volume of a cylinder is always calculated according to a single formula - the area of ​​\u200b\u200bits base is multiplied by the height of a cylindrical body. Semicircular structures in the room can be represented as part of a cylinder, based on this, calculations are made of the total volume of the cylinder, and then the excess part is subtracted from them, in accordance with the dimensions of the semicircular niche.

How to find the volume of a room

An assessment of the volume of premises is quite often required in the production of construction and repair work. In most cases, this is required to clarify the amount of materials needed for repairs, as well as for the selection effective system heating or air conditioning. Quantitative characteristics describing space, as a rule, require some measurements and simple calculations.

2. If the room has an incorrect or complex shape, the task becomes a little more complicated. Break the area of ​​​​the room into several simple figures and calculate the area of ​​\u200b\u200beach of them, having previously made measurements. Add up the resulting values, summing the area. Multiply the amount by the height of the room. Measurements must be carried out in the same units, for example, in meters.

5. Separately calculate the volumes of verandas, bay windows, vestibules and other auxiliary elements structures. Include this data in the total volume of all rooms in the building. Thus, you can easily find the volume of any room or building, the calculations are quite simple, try and be careful.

Room volume formula

How to calculate the volume of a room

Volume is a quantitative feature of a place. The volume of the room is determined by its shape and linear dimensions. The concept of capacity is closely intertwined with the concept of volume, in other words, volume interior space vessel, packing box, etc. Accepted units of measurement - in the SI measurement system and its derivatives - cubic meter m3, cubic centimeter, liter. You will need To measure the volume of a room, you will need a tape measure, a sheet of paper, a calculator, a pen. 1 Each room, for example a room, is, from a geometric point of view, a rectangular parallelepiped.

The parallelepiped is big figure, which has 6 faces. and it doesn't matter which of them is a rectangle. The formula for finding the volume of a rectangular parallelepiped is: V=abc. The number of a rectangular parallelepiped is equal to the product of 3 of its dimensions. Apart from this formula, you can measure the amount of space by multiplying the floor area by the height.

2 So start calculating the volume of the room. Determine the length of one wall, later determine the length of the 2nd wall. Take measurements on the floor, at the level of the plinth. Keep the tape measure straight.

At the moment, determine the height of the room, to do this, go to one of its corners, and accurately measure the height along the corner from floor to ceiling. Write down the acquired data on a piece of paper so as not to forget.

How to calculate the volume in m3 of concrete calculator

At the moment, proceed to the calculations: multiply the length of a long wall by the length of a short wall, multiply the acquired product by the height and you will get the required result.

The volumes of the premises are calculated in various occasions: 1) in the case of purchasing an air conditioner, since air conditioners are designed for a certain number of rooms; 2) in the case of installing heating radiators in rooms, since the number of sections in the radiator depends on the volume of the room. 3 If you have an irregularly shaped room, in other words, it consists of a seemingly huge parallelepiped and a small one. In this case, it is necessary to measure the number of each of them separately, and then add them up. If your room has an alcove. then its amount must be calculated using the formula for the volume of a cylinder. The number of any cylinder is equal to the product of the area of ​​​​the base and the height: V \u003d? r2 h, where. is the number "pi" equal to 3.14, r2 is the square of the radius of the cylinder, h is the height.

Imagine your alcove for yourself as part of a cylinder, calculate the amount of what seems to be the entire cylinder, later look at what part of this cylinder your alcove occupies, subtract the excess part from the total volume.

How to calculate the area of ​​a room?

If a room has four walls and has a standard geometric figure with right angles, then it is necessary to measure two walls and multiplying the obtained two numbers by each other we get the area of ​​​​the room, and for the volume you need to multiply the result by the height. but this is only with regular geometric shapes.

It is more difficult to find the area and dimensions when the shape of the room is the wrong size, for example.

Then you need to apply all the knowledge of geometry, namely, divide the room into several regular figures and, in accordance with the formulas of these figures, find their area, and then add all the results together, then you get the total area of ​​\u200b\u200bthe room. To find the height, you need to multiply the result of the total area by the height.

Things are even worse with non-standard premises with irregular wall and roof angles. Then you have to transfer all the dimensions of the room to paper, divide it into correct figures and based on each figure, find its area and volume, and then summarize the results.

The area of ​​the room does not include protrusions of windows and other things that are higher than the floor, but they are included in the calculation of the volume of the room.

How to calculate the area of ​​​​a room

In case of room measurement irregular shape for a more accurate calculation of the area, it is recommended to divide it into rectangles. By calculating the area of ​​each such plot, you can find out total area rooms by simply summing up all the results obtained.

If it is not possible to divide the room into rectangular sections, then you can try such shapes as a triangle or a sector of a circle. The area of ​​a triangle is calculated using Heron's formula: S=v**).

P - half-perimeter of a triangle, which can be calculated in this way: p \u003d / 2

Estimation of the volume of premises is quite often required in the production of construction and repair work. In most cases, this is required to clarify the amount of materials needed for repairs, as well as to select an effective heating or air conditioning system.

Quantitative characteristics describing space, as a rule, require some measurements and simple calculations.

1. The simplest case is when you want to determine the volume of a room with a regular rectangular or square shape. Using a tape measure, measure in meters the length and width of the walls, as well as the height of the room. It is most convenient to take measurements along the floor, along the baseboards. Multiply the obtained indicators of length, width, height and you will get the desired volume.

2. If the room has an irregular or complex shape, the task becomes a little more complicated. Break the area of ​​​​the room into several simple shapes (rectangles, squares, semicircles, and so on) and calculate the area of ​​\u200b\u200beach of them, having previously made measurements. Add up the resulting values, summing the area. Multiply the amount by the height of the room. Measurements must be carried out in the same units, for example, in meters.

3. When carrying out construction works the definition of the volume of the entire structure is determined by the standards. The so-called building volume of the ground part of the building with an attic can be calculated by multiplying the horizontal sectional area along the outer contours at the level of the lower floor. Measure full height buildings from the level of the clean floor to the top of the insulation attic floor. Multiply both numbers.

4. If there are floors of different sizes, determine the total volume of premises in the building by adding the volumes of all parts. In the same way, the volume is determined if the premises have different outlines and designs.

5. Separately calculate the volumes of verandas, bay windows, vestibules and other auxiliary elements of the structure (with the exception of covered and open balconies). Include this data in the total volume of all rooms in the building. Thus, you can easily find the volume of any room or building, the calculations are quite simple, try and be careful.

2.4 Capacity calculation public buildings and the size of their land

Public buildings house institutions and public service enterprises.

By specialization and types of services, public institutions and enterprises are divided into preschool (nurseries and kindergartens), schools, health care, cultural and educational, public utilities, trade and distribution, public catering, administrative and economic, etc.

Calculation of the volume of the room.

Compound public institutions for everybody inhabited place initially developed in the draft district planning, which presents the entire system of resettlement in the area and the placement of institutions and service enterprises in settlements. These developments are taken into account when determining the composition of public buildings in a particular populated area. This takes into account the possibility of further operation of existing buildings.

Capacity calculation or bandwidth institutions and service enterprises is produced according to the settlement norms (SNiP).

2.5 Listing design buildings and facilities

Public buildings house institutions and public service enterprises. By specialization and types of services, public institutions and enterprises are divided into:

Preschool children's (nurseries and kindergartens);

school;

healthcare,

cultural and educational;

· household;

· trade and distribution;

· Catering;

Administrative and economic and others.

According to the territorial coverage of services, they can be divided into the following groups:

1) servicing residents of several settlements;

2) services for residents of one populated area;

3) serving residents separate parts populated place.

The first group includes institutions located in regional centers and serving the entire population of the region (district Council of People's Deputies, House of Culture, post office, department store, etc.), as well as institutions serving a group of settlements and located in the largest of them, for example , in the central estates of farms (the village Council of People's Deputies, the office of the state farm, the board of the collective farm, high school, hospital, etc.). The second group consists of institutions serving all residents of one populated area. The third group includes institutions that serve residents of certain parts of a large populated area and are represented in it by several buildings located at different points (kindergartens and nurseries, schools, grocery stores, etc.).

This system of service establishments was called the "step system". It ensures the proximity of service establishments to residents. Thus, the first group includes occasional use institutions, the second - periodic use, and the third - provides for daily maintenance.

The composition of public institutions for each populated area is initially developed in the draft district planning, which presents the entire system of resettlement in the area and the placement of institutions and service enterprises in settlements. These developments are taken into account when determining the composition of public buildings in a particular populated area. At the same time, the possibilities of further operation of existing public buildings are taken into account.

The calculation of the capacity or throughput of institutions and service enterprises is carried out according to the calculated norms.

In accordance with the calculated data of public institutions, standard designs of public buildings are selected for a particular populated area. At the same time, preference should be given to such standard projects in which it is planned to place several public institutions in one building. At the same time, the construction and operating cost per unit volume of the building is reduced, its appearance becomes more interesting, and the architecture of the public center where the building is located is enriched.
