radii shoes for women-A civil engineer should have the data

12 a square wall requires 64 standard brick wall of a square
18 need 96 standard brick wall of a square
24 need 128 standard brick wall of a square to be
37 to 192 standard bricks < br> 49 square wall of a brick to be the standard for the 256
formula:
wall unit dosage of 240 cubic meters of 1 / (0.24 * 0.12 * 0.6)
wall unit dosage of 370 cubic meters of 1 / ( 0.37 * 0.12 * 0.6)
hollow wall 24 need more than 80 square blocks of a standard brick
an ordinary residential buildings the amount of concrete and steel consumption:
1, multi-storey masonry house:
steel 30KG/m2
concrete 0.3-0.33m3/m2
2, multi-storey frame
38-42KG/m2
reinforced concrete 0.33-0.35m3/m2
3, 11-12 high-rise 50-52KG/m2
reinforced concrete layer
0.35m3/m2
4, 17-18 senior 54-60KG/m2
reinforced concrete layer
0.36m3/m2
5,paul smith pants, 30-story high-level H = 94 米
reinforced 65-75KG/m2
concrete 0.42-0.47m3/m2
6, 28-story high-rise apartments H = 90 米
steel 65-70KG/m2
concrete 0.38-0.42m3/m2
7, villas, and the amount of steel between the amount of concrete masonry residential and multi-layer top 11-12
7 degrees above the data area by seismic structural design rules
Second, ordinary multi-storey residential building construction budgets and economic indicators
1,oakley prescription, outside doors and windows (not including the cell door, security door) area of ​​the building area of ​​0.20-0.24
2, the template area of ​​the building area of ​​about 2.2 < br> 3, the outdoor area of ​​the floor area of ​​plaster about 0.4
4, interior plaster floor area of ​​3.8
area of ​​the three construction efficiency
1, a plaster plaster work one day in the 35 square meters
2, brick work one day a puzzle block brick 1000-1800
3, working one day a brick puzzle 800-1000 hollow brick block
4, tile 15 square meters
5, scraping white pass 300 square meters / day , the second over 180 square meters / day, the third time pressure light 90 m / 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 about 525 bricks (sub-thickness of the wall)
6 , one cubic meter of hollow brick 175 or so
7, one clean and the sand screen to be 1.3 square

ordinary sand that different points of view:
1, ordinary multi-storey residential masonry: steel 25-30KG/m2 which affordable housing is 16--18KG/m2.
2, ordinary multi-storey masonry house, outdoor area of ​​the plaster floor area 0.5 - 0.7.
3, ordinary multi-storey masonry residential area of ​​the building area template 1.3 - 2.2, according to the in-situ plate number, column densities vary greatly.
4,radii shoes for women, working one day a puzzle brick walls 1000-1800 block 240, 370 or 500 wall 2000--3000 block.
5, reinforced concrete weight 2200KG/m3, plain concrete weight 2100KG/m3.
6, project stone weight 1800KG/m3. )
Flat, plate, strip W = 0.00785 × width × thickness

square steel W = 0.00785 × side length 2

round bar, wire rod, steel wire W = 0.00617 × diameter 2

steel wall thickness W = 0.02466 × (OD - Wall Thickness)

equilateral angle W = 0.00785 × thick side (2 side width - edge thickness)
< br> equilateral angle W = 0.00785 × thick side (long side short side width + width - edge thickness)

beam waist W = 0.00785 × thickness [high + f (leg width - waist thick )]

channel W = 0.00785 × waist thick [high + e (leg width - waist thick)]

Remarks

1, angle steel, I-beam and trough Steel's formula is very complex and accurate, the table used to calculate the approximate short form.

2, f values: general models and with a of 3.34, with b 2.65, with c as 2.26.

3, e value: general models and with a of 3.26, with b 2.44, with c, 2.24.

4, the length of the units are in millimeters
