The construction calculator will help you accurately calculate the need for bricks, knowing the initial data. Quantity determination required material made taking into account the type of masonry and brick. In the calculations, either the area of \u200b\u200bwalls and partitions or their volume is used.

brick consumption

Solution consumption

To avoid interrupting the construction process due to a shortage of bricks and undesirable spending on the import of purchased building materials, it is better to bring everything at once. Excess material significantly increases the cost of construction. Therefore, if you need to calculate brick for masonry, the online calculator on the construction site is the best modern tool for accurate calculation.

The principle of determining the consumption of bricks based on the volume of walls

The methodology is based on the determination of the quotient of dividing the total volume of walls (corrected taking into account the deduction of openings for windows and doors) by the volume of one brick. The result is the required amount in pieces for brickwork.

In practice, the problem is solved with the passage of several stages:

determination of the areas of internal walls and partitions, external bearing walls, differing in thickness;
calculation of the areas of window and door openings;
subtracting the size of the openings from the value of the wall area;
calculation of wall volumes by multiplying their corrected area by the thickness;
calculation of a brick for laying external, internal walls and partitions by dividing the obtained wall volumes by the volume of one brick.

The task is complicated by the fact that between the bricks there are seams filled with mortar. Them standard thickness taken equal to 10 mm, but may be less if the brick has an ideal geometry. A few millimeters of mortar between bricks on a scale of the entire building grows into a rather impressive value, reducing the consumption of bricks.

The simplified calculation is based on the standard dimensions of a single "normal form" brick (1NF) - 250 x 120 x 65 mm (length, width, height). In a cubic meter of masonry of such bricks, exactly 512.82 pieces are placed. Taking into account the seams (10 mm), the difference will be 118 bricks, which for the entire object is a mountain of unnecessary material. Using the calculator online, the purchase of excess building materials will be excluded.

Any batch of bricks initially has a certain percentage of defects. Losses are inevitable during loading, transportation and unloading. This damage increases the calculated amount by 5 - 8%.

An example of calculating the required number of bricks per unit area

Design decision one-story house(ceiling height - 3 m) suggests its rectangular shape with a length of 15 meters and a width of 8 meters. The initial data are also:

length of internal load-bearing walls - 22 m;
partitions length - 26 m;
the number of doors in the outer walls - 2 pcs. (size 1.3 x 2.15 m);
the number of doorways in the inner walls - 4 pcs. (size 1.25 x 2.1 m);
number of windows - 7 (opening size 1.4 x 1.85 m);
type of laying of external walls - in 2 bricks (double);
internal load-bearing walls are designed to be 1.5 bricks (0.38 m);
the thickness of the partitions is 0.5 bricks (0.12 m).

The calculations come down to the definition:

1. Adjusted masonry area of outer walls (without openings):
S \u003d ((2 x 15 x 3) + (2 x 8 x 3) - (7 x 1.4 x 1.85)) \u003d ((90 + 48) - 18.13) \u003d 119.86 m².
2. Areas of internal walls:
V ext.st. \u003d ((22 x 3) - 4 (1.25 x 2.1)) \u003d 55.5 m².
3. Areas of partitions:
V lane \u003d (26x 3) \u003d 78 m².

Using the reference table, the value is determined, how many bricks are in 1 m2 of masonry:

Based on the fact that for a unit area of \u200b\u200bmasonry of 2 bricks (using a double brick), 104 of them are needed, then on the outer walls of the entire building it is necessary:

119.86 x 104 \u003d 12466 pcs. double bricks.

For internal load-bearing walls of 1.5 bricks (one and a half bricks), it is necessary: 78 x 55.5 \u003d 4329 pieces, where 78 is an average value showing how many one and a half bricks are in 1 m2 of masonry with a thickness of 0.38 m.

For partitions of 0.5 bricks of material, you will need: 78 x 51 \u003d 3978 pieces of a single brick.

That. single bricks need to be purchased 3978 x 1.08 = 4296 pieces, one and a half - 4329 x 1.08 = 4675 pieces, and double bricks - 12466 x 1.08 = 13463 pieces - taking into account 8% of waste from battle and marriage.

Using the brick laying calculator, the calculation of its required amount is reduced only to entering the initial data.

Before starting any construction, including the construction of a basement, you need to decide on the required amount building materials and perform the calculation of the brick on the base. After all, you see, it will not be very pleasant if, in the midst of construction, it turns out that there is not enough material. This will not only stop the entire construction, but also increase its cost, due to additional transportation.

To perform such calculations, there is a special calculator for calculating bricks per base, however, you can perform this operation yourself. Next, we'll look at how to do this.

General information

Before taking up a piece of paper and a pen, or a calculator for calculating a brick for a plinth, let's consider what this part of the structure is. So, the base is that part of the building that encloses the space between the foundation and the floor. It is also called the above-ground part of the foundation ().

When calculating the base, it should be borne in mind that it performs a number of functions:

It protects the walls of the house from atmospheric precipitation, such as rainwater, melting snow, dew, and also prevents capillary suction, i.e. protects from moisture coming from the ground. If its design is not high, then the wall will become damp and, as a result, covered with mold.
It takes on the mechanical effects that the backfilled earth has inside the house.
It takes on the load from the walls of the house.

Therefore, it is very important to perform the calculation of the base. Experts say that its height should be more than the maximum snow cover height over the past few years. As for the maximum height of the structure, there are no restrictions.

If you decide to build a building with a basement floor with your own hands, then you can make the height larger for comfortable use of the room.

Advice! A house with a high base looks more elegant and solid than with a low one.

Material calculation

What parameters do you need to know

So, in order to calculate the number of bricks per base, you need to know the following data:

The length of the structure is determined by summing the lengths of all walls. For example, if a 10x8 house is being built, then the length of the walls is 10x2 + 8x2 = 36 meters.
The thickness of the structure.
Base height.
Material size. The parameters of a standard full-bodied product are 250x120x65 mm.

These same parameters will need to be entered into the brick base calculator if you decide to get the result in this way.

Note! Only a solid block can be used for the base. Silicate double brick M 150 is also suitable.

We determine the amount of building material

As an example, we will find out the amount of material for a base one meter high, with masonry in one block, i.e. 0.25 m and house size 10x8 m ().

The instruction looks like this:

First of all, you need to convert all dimensions to meters, for ease of calculation. As a result, the dimensions of the block will be 0.25x0.12x0.065m. The length of the structure, as we have already found out, will be - 10x2 + 8x2 = 36 meters.
Next, for a given thickness, length and height of the walls, you need to calculate the volume of masonry, for this we perform the following steps - 36x0.25x1 \u003d 9 cubic meters.
Then you need to find out the volume of one product - 0.25x0.12x0.065 \u003d 0.00195 cubic meters.
Now we divide the total volume of the walls by the volume of bricks, as a result it turns out - 9 / 0.00195 ~ 4616 pieces. Accordingly, knowing the amount of material, you can find out what the price of building a structure is.

In the photo - laying the base for calculating the material

If the base will have openings, then their volumes must be subtracted from the total volume of the masonry. For example, the size of the window opening is 0.8x1x0.25 m. In this case, the volume will be - 0.8x1x0.25 = 0.2 cubic meters.

If there is only one window opening, then the volume of masonry will be reduced to 9-0.2 = 8.8 cubic meters. If there are more openings, then, of course, their volume should also be subtracted. To double-check the correctness of the calculations, the calculator will also tell you how much brick you need per base, unless, of course, you have a computer and the Internet at hand.

Advice! You need to purchase materials with a small margin, given the possible marriage or damage during transportation.

There is also another way to perform the calculation:

First of all, it is necessary to determine how much material is located in one row of masonry. To do this, the length of the base should be divided by the width of the block, as a result it turns out - 36 / 0.12 = 300 pieces.
Then you need to find out the number of such rows. To do this, the height of the structure must be divided by the height of the block 1/0.065=15.38 rows.
Then, by simple multiplication, we find required amount material - 15.38 * 300 = 4614 pieces.

I must say that above we considered the simplest calculations, if you need to get a more accurate result, then you should definitely take into account the thickness of the seam, which is usually about 10 mm. If you feel unsure, you can also seek professional help.

Advice! Since a large load is placed on the base, and the durability of the entire house depends on its strength, the masonry must be reinforced after every four rows. In this case, the seams must be carefully filled with mortar and the use of cracked blocks should be avoided.

Conclusion

To calculate the required amount of building material, of course, the easiest way is to use a brick calculator on the plinth, however, if only a pen and paper are at hand, then, as we have seen, it will not be difficult to perform this operation on your own. The main thing in this matter is attentiveness, in addition, do not be too lazy to double-check the result several times ().

Before starting any construction, it is necessary to determine the amount of building materials. It is not very pleasant to discover a lack of consumables in the midst of work, whether it be a brick or components of a masonry mortar.

This will slow down the whole process, and the cost of additional transportation will increase the cost of the entire construction site as a whole. So start construction by calculating the need for basic and additional building materials.

Socle - the beginning of calculations

The basement of a building is a part of the walls enclosing the underground space and erected directly on the foundation. The top of the base corresponds to the floor level of the first floor. High demands are placed on the resistance of the plinth structure to external influences and the overall load from the upstairs rooms.

Take, for example, the building material from which it can be built. It should be a durable product that is resistant to various atmospheric influences:

Concrete as a continuation of the monolithic strip foundation.
foundation blocks.
Clay or silicate blocks.

If, for some reason, you decided to build this part of your house from clay blocks and undertook to do the work yourself, then calculating the brick for the base is your concern.

Note! Of course, you can contact the experts with this or use the calculator for calculating bricks for the base, posted on the websites of manufacturers of masonry materials. But you wanted to do everything yourself!

After carefully reading this article, you will learn how to calculate the number of bricks per base, so as not to deprive yourself and not overpay extra money.

Calculation

So, to calculate the need for building material for your warping, you will need the following initial information:

Structure length. It is determined by summing up all the lengths of the enclosing walls of the house.

Note! For example, to make it more clear: with a house size of 10x8 m - the total length of the base is 10 + 8 + 10 + 8 = 36 m.

Basement wall height.
Construction thickness. Usually a minimum of ½ brick or more at will or justified need.
Basement brick dimensions, from which the masonry will be performed.

Note! The standard size of the basement is 250x120x65 mm, one and a half - 250x120x88 mm, double - 250x120x138 mm.

The number and dimensions of window and door openings, if any.

You can use blocks of any size, it doesn't matter here. It is important to apply with high compressive strength, bending and freezing resistance.

You can take one and a half, double silicate brick M 150, but with subsequent lining of the base ceramic tiles or plastering to increase the hydrophobicity of the structure.

Now the instruction for calculating the number of bricks for a basement device with a height of 1 m, a thickness of one block is 0.25 m, for a house measuring 10x8 m. We will calculate using standard sizes on the socle brick single.

Let's translate the dimensions of the material into "meters" for ease of measurement. For a single block with dimensions of 250x120x65 mm, this will be 0.25x0.12x0.065 m. The length of our structure is 10 + 8 + 10 + 8 = 36 m.

The amount of materials also depends on the initial size of the basement brick and what type of masonry is used.

The first simplest option

For a given height and thickness of the plinth, respectively 1 m and 0.25 m, we calculate:

The masonry volume is 36 multiplied by 1 and 0.25 (36x1x0.25 \u003d 9 m3).
The volume of one item. Also multiplied (0.25x0.12x0.065 = 0.00195 m3).
We divide the total volume of masonry by the volume of one block (9 / 0.00195 \u003d 4615.38 pcs.) You will need 4616 bricks.

In the case when openings are planned in your basement, subtract their volume from the total volume of brickwork. For example: the volume of a window opening with a size of 0.8x1 m is 0.8x1x0.25 = 0.2 m3. Taking into account such an opening, the volume of our masonry is reduced to 8.8 m3 (9-0.2 = 8.8 m3). Further, repeating the simplified calculation, we obtain the required number of blocks.

Second option

We begin the calculation in another way by determining how many materials are in one row of our masonry.

We divide the length of the base by the width of the brick, since the masonry is supposed to be a thickness of building brick. We get 36 / 0.12 = 300 products in each row of masonry.
Now we find out the number of such rows by dividing the height of the wall - 1m by the height of the clay block - 0.065m, 1 / 0.065 = 15.38 rows.
By simple multiplication, we get the amount of materials that will be required for the work, as in the first option.

The simplest calculations are described above, with a refined calculation, it is necessary to take into account the thickness of the mortar joint (about 10 mm). It is also necessary to add to the length, width or thickness of the material, depending on the configuration of the masonry, the thickness of the mortar layer.

And finally, ask the experts for advice, they don’t take money for consultations, but the price of the issue will be known more precisely - the purchase of materials.

Important! Since the base is a heavily loaded structure and the entire building depends on its strength, it should be reinforced brickwork every four rows. Laying should be arranged with dressing, carefully fill the seams with mortar and avoid cracked products.

Conclusion

As you can see, everything is quite simple, although this is only part of the calculations. After all, if you decide to build a house, then you will need to find out the total amount of building materials. To do this, it is necessary to take into account everything, up to the dimensions of the interior partitions (depending on what they are made of).
