Each construction, whether it is the construction of a house, a country cottage, a summer house or a garage, requires the correct calculation of materials, in particular the number of bricks in 1m2 of masonry. This will allow you to optimize costs as much as possible. After completing the calculations, you will be able to purchase building bricks for the construction of the entire facility in full. When calculating, the percentage of defective or broken material should be taken into account. Typically, this factor is 7% of the purchase lot. In addition, it is necessary to determine the thickness of the walls of the future structure. It depends on the climatic conditions of the area where the building is located. It is better to purchase products from one batch, since in another they may have differences in shades.
Standard dimensions and their names
A brick, which has a normal format and is marked NF, is characterized by dimensions of 25 x 12 x 6.5 cm. According to State Standards, a face measuring 25 x 12 cm is called a bed. The side with dimensions of 25 x 6.5 cm is called a spoon, and 12 x 6.5 cm is called a poke.
Varietiesbrick
When calculating how many bricks in 1m2 of masonry, one should take into account the type of product from which the construction will be carried out. This is the only way to accurately calculate the required amount of material.
Building brick happens:
- single, size 250 x 120 x 65 mm;
- one and a half - 250 x 120 x 88 mm;
- double - 250 x 120 x 138 mm.
During construction, all varieties of this material are used, but a single look is best suited for cladding. A building with this finish looks the most aesthetically pleasing.
Masonry methods
The consumption of bricks depends on the methods of laying the building material. The fastest and most economical way to build a house is to build it "in half a brick" (the spoon part is located outside). The wall in this case will have a thickness of 12 cm. When building in this way, the number of bricks in 1m2 of masonry is saved up to two times. However, a house built using this option needs to be insulated.
The brick laying method - when the material is poke on the outside. Then the wall thickness is 25 cm. The brick consumption per m2 of masonry in this case increases. Walls with this method are able to withstand any load, evenly distributed.
A building with 38 cm thick walls will be more durable.
The most popular way is the construction of cottages or other buildings with walls of 51 cm. This thickness comes out withmethod of laying "in two" bricks.
Buildings with walls of 64 cm are more durable, strong and do not need insulation. The thickness is formed by laying "two and a half" bricks.
If you lay a full-bodied product with air gaps, from 5 to 8 cm wide, its consumption is reduced by approximately 20%. It is also possible to reduce the amount of material used with the well masonry of the walls, which is laid out in two parallel rows “in half a brick”. They are interconnected by vertical or transverse jumpers. Formed wells are filled with insulating material. To reduce settlement, dry backfill is poured with lime mortar after 35–45 cm.
Calculation of building product
After determining the thickness of the walls of the future building, they begin to calculate the number of bricks needed for its construction, multiplying the perimeter length by the height of each surface. Then the openings of doors and windows are subtracted from the result and the area of \u200b\u200bthe brick wall is obtained.
The basis for calculations is the standard quantity: 480 bricks, size 250 x 120 x 65 mm, per 1m2. All calculations during the construction of various buildings are made on the basis of this indicator and the method of masonry. The construction of a half-brick wall using the poke method requires twice as much material consumption as the spoon method.
To find out the number of bricks in 1m2 of brickwork, you need to divide 480 by 4 (product length 25 cm, 4 pieces per 1 meter). We get 120 pieces. To build a warm house, the expense should be multiplied2 or 2.5 times, and for the construction of a fence, reduce by half.
Calculation of facing material
There are types of material that differ in their dimensions from the usual standard sizes.
The standard for a glazed item is 220 x 105 x 48 mm, while the standard for a large-format one is 327 x 102 x 215 mm. This is a very fragile brick and it is used half. It is difficult to make an accurate calculation. And yet, the number of bricks in 1m2 of masonry will be 95 pieces, and large format - 14 pieces.
Facing products do not have certain standard sizes. Therefore, the calculation of the amount per 1 m2 is made separately for each type.
Calculation of bricks using mortar
When making calculations, a mortar joint is taken into account, the standard thickness of which is 1 cm. But everyone uses it differently. And in order to calculate accurately, it follows from the number of products per 1 m2 subtract 10% - and the result is ready. This applies to standard sizes only. When counting a facing or double brick, the error will be 5%. Brick consumption per 1 m22 masonry "in half a brick" using a mortar joint will be:
- red construction - 54 pcs.;
- standard cladding - 85 pieces;
- large-format - 13, the number increases every 3 meters by 14 pcs.
So, to determine the number of bricks to build, you need:
- Calculate the perimeter of a building.
- Producecalculation of the area of the outer walls (multiply the length by the height of the wall and subtract the area of the openings of windows and doors).
- Choose laying method.
- Determine the number of products for construction (the area of the walls is multiplied by the number of bricks in 1 m22 of the selected masonry).
