A square wall of 18 needs 96 standard bricks.
A square with 24 walls needs 128 standard bricks.
A square with 37 walls needs 192 standard bricks.
A square with 49 walls needs 256 standard bricks.
Calculation formula:
The consumption of 240 wall tiles per cubic meter is 1/(0.24*0. 12*0.6).
The consumption of 370 wall tiles per cubic meter is 1/(0.37*0. 12*0.6).
A square hollow 24 wall needs more than 80 standard bricks.

The above data are designed according to the rule of earthquake 7 degree zone.
Second, the ordinary multi-storey residential building construction budget economic indicators
1. Outdoor doors and windows (excluding unit doors and security doors) account for 0.20-0.24 of the construction area.
2. The formwork area accounts for about 2.2% of the building area.
3. The outdoor plastering area accounts for about 0.4 of the building area.
4. Indoor plastering area accounts for 3.8% of the building area.
Third, the construction effect
1, the daily plastering capacity of a Plaster workers is 35 square meters.
2. A bricklayer lays 1000- 1800 red bricks a day.
3. A bricklayer lays 800- 1000 hollow bricks a day.
4. Tiles15m2
5. The first scraping is 300 m2/ day, the second scraping is 180 m2/ day, and the third scraping is 90 m2/ day.
Fourth, the basic data
1, concrete weight 2500KG/m3.
2. The reinforcement weight per linear meter is 0.00617 * d * d * d.
3, dry sand weight 1500KG/m3, wet sand weight 1700KG/m3.
4. The stone weight is 2200KG/m3.
5. About 525 red bricks per cubic meter (wall thickness)
6. One cubic meter of hollow brick is about 175.
7. Screen side cleaning sand requires 1.3 cubic meters of ordinary sand.
A little different view:
1. General multi-storey masonry residence: steel bar 25-30KG/m2, of which affordable housing 16- 18kg/m2.
2. For general multi-storey masonry houses, the outdoor plastering area accounts for 0.5-0.7 of the construction area.
3. Generally, the formwork area accounts for 1.3-2.2 of the building area, which varies greatly according to the number of cast-in-place slabs and the density of columns.
4. A bricklayer builds 240 brick walls a day1000-1800,370 or 500 walls 2000-3000.
5. The weight of reinforced concrete is 2200KG/m3, and that of plain concrete is 2 100KG/m3.
6. The weight of engineering stone is 1800KG/m3. )
0.6 17 is the reinforcement weight per meter of circle 10. The weight of steel bars is proportional to the square of the diameter (radius).
G=0.6 17*D*D/ 100
Weight per meter (kg) = rebar diameter (mm)× rebar diameter (mm)×0.006 17.
In fact, it is very simple to remember the weight of steel bars commonly used in construction projects: φ 6 = 0.222kgφ 6.5 = 0.26kgφ 8 = 0.395kg φ10 = 0.617 kgφ12 = 0.888kgφ14 =/kloc. 438+08 = 2.0kgφ24 = 2.47kgφ22 = 2.98kgφ25 = 3.85kgφ28 = 4.837kg ............
Steel bars below φ 12 (including 12) and φ 28 (including 28) generally take three decimal places, and steel bars from φ 14 to φ 25 generally take two decimal places.
φ 6 = 0.222kg.
φ8 = 0.395kg
φ 10 = 0.6 17kg
φ12 = 0.888kg.
φ 14 = 1.2 1kg
φ 16 = 1.58kg
φ 18 = 2kg
φ 20 = 2.47kg.
22 = 3Kg
φ 25 = 3.86kg.
I have an empirical formula. Just calculate your own table. You can also buy a book with a watch, which is also very convenient to use.
A simple formula for calculating the theoretical weight of steel
Material Name Theoretical Weight W (kg/m)
Flat steel, steel plate and steel strip w = 0.00785× width× thickness
Square steel w = 0.00785× side length 2
Round steel, steel wire and steel wire w = 0.006 17× diameter 2.
Steel pipe w = 0.02466× wall thickness (outside diameter-wall thickness)
Equiangular W = 0.00785× side thickness (2 side width-side thickness)
Unequal angle steel w = 0.00785× side thickness (long side width+short side width-side thickness)
I-beam w = 0.00785× waist thickness [height +f (leg width-waist thickness)]
Channel steel w = 0.00785× waist thickness [height +e (leg width-waist thickness)]
comment
The exact calculation formulas of 1, angle steel, I-beam and channel steel are very complicated, so the approximate values are calculated by table simplification.
2.f value: 3.34 for general model and A model, 2.65 for B model and 2.26 for C model. ..
3.e value: 3.26 for general model and A model, 2.44 for B model and 2.24 for C model. ..
4. All length units are millimeters.
