7, villas, and the amount of concrete between steel consumption and high-level multi-storey residential masonry layer 11-12
7 degrees above the data zone rules by seismic design
Second, ordinary multi-storey residential building construction budget economic indicators
1, outside doors and windows (not including cell door, security door) area of the floor area of 0.20-0.24
2, total construction area of 2.2 template area around
3, the outdoor area of the floor area of plaster about 0.4
4, interior plaster total construction area of 3.8
area of the three, the construction efficiency

3, a hollow brick brickwork 800-1000 day puzzle pieces
4, 15 square meters of ceramic tile
5, 300 square meters of first pass scraping white / day, and the second over 180 square meters / day, the third time calendar of 90 square meters / day
four basic data
1, concrete weight 2500KG/m3
2, the weight of steel per meter 0.00617 * d * d
3, dry sand weight 1500KG/m3, wet sand weight 1700KG/m3
4, stone weight 2200KG/m3
5, one cubic meter of red about 525 bricks (sub thickness of the wall)
6, one cubic meter of about 175 hollow brick
7, screening 1.3 one side clean sand to be a little different point of view of ordinary sand
:
1, ordinary multi-storey Masonry Residential: reinforced 25-30KG/m2, including affordable housing for the 16--18KG/m2.
2, ordinary multi-storey masonry houses, plastering the outdoor area of the floor area of 0.5 - 0.7.
3, ordinary multi-storey masonry residential area of the building area template 1.3 - 2.2, according to the number of cast panels, a large column density.
4, a brick wall brickwork 1000-1800 240 puzzle pieces a day, 370 or 500 Wall 2000 - 3000 block.
5, reinforced concrete weight 2200KG/m3, plain concrete weight 2100KG/m3.
6, project stone weight 1800KG/m3. )
0.617 is the weight per meter of reinforced round of 10. Steel weight and diameter (radius) proportional to the square.
G = 0.617 * D * D/100
weight per meter (Kg) = bar diameter (mm) × the diameter of steel bar (mm) × 0.00617
fact, remember the weight of steel commonly used in construction projects is also very simple φ6 = 0.222 Kg φ6.5 = 0.26kg φ8 = 0.395kg φ10 = 0.617kg φ12 = 0.888kg Φ14 = 1.21kg Φ16 = 1.58kg Φ18 = 2.0kg Φ24 = 2.47kgΦ22 = 2.98kgΦ25 = 3.85kgΦ28 = 4.837kg ............
Φ12 (including 12) below and Φ28 (including 28) of the steel generally take three digits after the decimal point, Φ14 Φ25 reinforced to take two digits after the decimal point generally
Φ6 = 0.222Kg
Φ8 = 0.395Kg
Φ10 = 0.617Kg
Φ12 = 0.888Kg
Φ14 = 1.21Kg
Φ16 = 1.58Kg
Φ18 = 2Kg
Φ20 = 2.47Kg
Φ22 = 3Kg
Φ25 = 3.86Kg
formula I have the experience, you calculate a table on it. Forms can also go to buy a book with them is also very convenient.
theoretical weight of steel materials, simply type the name of
theoretical weight W (kg / m)
flat steel, steel sheet, strip W = 0.00785 × width × thickness
square steel W = 0.00785 × side 2
round bar, wire rod, steel wire W = 0.00617 × diameter 2
steel wall thickness W = 0.02466 × (OD - thickness)
equilateral angle W = 0.00785 × edge thickness (2 edge width - Edge thickness)
unequal angle W = 0.00785 × edge thickness (long side short side width + width - edge thickness)
beam W = 0.00785 × waist thick [high + f (legs wide - waist thick)]
channel W = 0.00785 × waist thick [high + e (leg width - waist thick)]
Notes
1, angle steel, channel steel I-beam and the exact formula is complex, the table used to calculate the approximate simplified.
2, f values: general models and with a, 3.34, 2.65 with b, with c, was 2.26.
3, e values: general models and with a, 3.26, 2.44 with b, with c, 2.24.
4, the length of the units are in millimeters

50 -52KG/m2
concrete 0.35m3/m2
4, 17-18 senior 54-60KG/m2
reinforced concrete layer
0.36m3/m2
5, top layer H = 94 30 m
65-75KG/m2
reinforced concrete 0.42-0.47m3/m2
6, 28-story high-rise apartments
H = 90 米 0.38-reinforced concrete 65-70KG/m2
0.42m3/m2
7, villas, and the amount of concrete between steel consumption and high-level multi-storey masonry house more than 11-12 layers of data between the
7 degree earthquake zone rules by design
Second, the general multi-storey residential building construction budget economic indicators
1, outside doors and windows (not including cell door, security door) area of the floor area of 0.20-0.24
2, total construction area of 2.2 template area around
3, outdoor wiping gray area of the floor area of around 0.4
4, interior plaster total construction area of 3.8
area of the three, the construction efficiency

2, a brick works 1000-1800 blocks of red brick puzzle day
3, a hollow brick brickwork 800-1000 puzzle pieces a day
4, tile 15 square meters
5, 300 square meters of first pass scraping white / day, and the second over 180 meters / day, the third time calendar of 90 square meters / day
four basic data
1, concrete weight 2500KG/m3
2, the weight of steel per meter 0.00617 * d * d
3, dry sand weight 1500KG/m3, wet sand weight 1700KG/m3
4, stone weight 2200KG/m3
5, about one cubic meter of red brick 525 (min thickness of the wall)
6, 175 one cubic meter of air brick or so
