Learn to count bricks before moving them
One square of 12 walls requires 64 standard bricks
One square of 18 walls requires 96 standard bricks
One square of 24 walls requires 128 standard bricks
One square of the wall should be 192 standard bricks
One square of 49 walls shall be 256 standard bricks
Calculation formula:
Unit cubic meter 240 wall brick consumption 1/(0.24*0.12*0.6)
Unit cubic meter 370 wall brick consumption 1/(0.37*0.12*0.6)
Hollow 24 wall one square needs more than 80 standard bricks

6. The 28th floor of high-rise serviced apartment H= 90m
Steel 65-70 kg/m2
Concrete 0.38 0.42 m3 / m2
7. The amount of concrete and steel used in the villa is between the multi-storey masonry residence and the high-rise 11-12 floors
The above data are designed according to the seismic 7 degree zone rule structure
Ordinary multi-storey residential building construction budget economic indicators
1. Outdoor doors and Windows (excluding unit doors and security doors) occupy 0.20-0.24 of the building area
2. The template 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
The construction effect
1, a plasterer one day plasterer in 35 square meters
2. A brick worker builds 1000-1800 red bricks a day
3. A brick worker builds 800-1000 hollow bricks a day
4, ceramic tile 15 square meters
5. The first time is 180 square meters/day, the second time is 130 square meters/day, and the third time is 80 square meters/day
Basic data
1, concrete weight 2500KG/m3
2, steel bar weight per meter 0.00617* D *d
3, dry sand weight 1500KG/m3, wet sand weight 1700KG/m3
4, stone weight 2200KG/m3
5, a cubic meter of red brick about 525 pieces (wall thickness)
6, a cubic meter of hollow brick 175 pieces
7. One side of clean sand screening needs 1.3 square meters of ordinary sand
Remark:
1, general multi-layer masonry house: reinforced 25-30kg /m2, which is 16--18KG/m2 for economic housing.
2. For general multi-storey masonry houses, the outdoor plastering area accounts for 0.5-0.7 of the building area.
3. In general multi-storey masonry houses, the template area accounts for 1.3-2.2 of the building area, which varies greatly according to the number of cast-in-place slabs and column density.
4, a brick worker a day build 240 brick walls 1000--1800, 370 or 500 walls 2000--3000.
5, reinforced concrete weight 2200KG/m3, plain concrete weight 2100KG/m3.
6, project stone weight 1800KG/m3.
0.617 is a circle of 10 bars per meter weight. The weight of reinforcement is proportional to the square of the diameter (radius).
G=0.617*D*D/100 Weight per meter (Kg) = diameter of steel bar (mm)× diameter of steel bar (mm)×0.00617
In fact, it is easy to remember the weight of steel bars commonly used in construction projects:
Phi 6 = 0.222 Kg
Phi 6.5 = 0.26 kg
Phi 8 = 0.395 kg
Phi 10 = 0.617 kg
Phi 12 = 0.888 kg
Φ 14 = 1.21 kg
Φ 16 = 1.58 kg
Φ 18 = 2.0 kg
Φ 24 = 2.47 kg
Φ 22 = 2.98 kg
Φ 25 = 3.85 kg
Φ 28 = 4.837 kg
φ 12(including 12) and φ 28(including 28) steel bar after the decimal point generally take three digits, φ 14 to φ 25 steel bar after the decimal point generally two digits
Φ 6 = 0.222 Kg
Φ 8 = 0.395 Kg
Φ 10 = 0.617 Kg
Φ 12 = 0.888 Kg
Φ 14 = 1.21 Kg
Φ 16 = 1.58 Kg
Φ 18 = 2 kg
Φ 20 = 2.47 Kg
Φ 22 = 3 kg
Φ 25 = 3.86 Kg
Simple formula for calculating theoretical weight of steel
Material Name Theoretical weight W (kg/m)
Flat steel, steel plate, steel strip W = 0.00785× width × thickness
Square steel W = 0.00785× side length 2
Round steel, wire, steel wire W = 0.00617× diameter 2
Steel tube W = 0.02466× wall thickness (outer diameter -- wall thickness)
Equilateral Angle steel W = 0.00785× edge thickness (2 edge width -- edge thickness)
Unequal Angle steel W = 0.00785× edge thickness (long side width + short side width - edge thickness)
I-steel W = 0.00785× waist thickness [height + F (leg width - waist thickness)]
Channel W = 0.00785× waist thickness [height + E (leg width - waist thickness)
Remark:
1, the exact calculation formula of Angle steel, I-steel and channel steel is very complicated, tabular simplified formula is used to calculate approximate value.
2. F value: 3.34 for general models and those with A, 2.65 for those with B and 2.26 for those with C.
3. E value: 3.26 for general models and those with A, 2.44 for those with B and 2.24 for those with C.
4. Each length unit is mm.
