A, ordinary residential building concrete consumption and steel consumption:
1. Multi-storey masonry residence: reinforcement: 30KG/m2.
Concrete: 0.3 ~ 0.33 m3/m2
2. Multilayer frame: steel bar: 38 ~ 42kg/m2.
Concrete: 0.33 ~ 0.35 m3/m2
3. Small high-rise building 1 1 ~ 12: reinforcement: 50 ~ 52kg/m2.
Concrete: 0.35 m3/m2
4. High-rise 17 ~ 18: steel bar: 54 ~ 60kg/m2, concrete: 0.36m3/m2.
5. H = 94m for the 30th floor of the high-rise building: steel bar: 65 ~ 75kg/m2；; Concrete: 0.42 ~ 0.47m3/m2.
6. 28th floor of high-rise serviced apartment: H = 90m; reinforcement: 65 ~ 70kg/m2；; Concrete: 0.38 ~ 0.42m3/m2.
7. Villa: The amount of concrete and steel is between the multi-story masonry residence and the high-rise building11~12; 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. The area of outdoor doors and windows (excluding unit doors and security doors) accounts 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. A Plaster workers posted 35 square meters a day.
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.
6, two steel workers can tie a beam 12 meters long, with three rows above, three rows below and six hoops.
7.20 rebar workers can complete the double-layer two-way slab rebar within the range of 54× 40m every day.
8. 12 concrete workers (two shifts) completed 1000 cubic meters of concrete (non-vertical structure) in about 20 hours.
6 ~ 8 is my own statistics, which may not be accurate.
Fourth, the basic data
1, concrete weight 2500KG/m3.
2. The reinforcement weight per linear meter is 0.006 17×d×d 3.
The weight of dry sand is 1500KG/m3,
The weight of wet sand is 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.
Supplement:
In general frame structure, the steel bar worker is half that of the carpenter.
The number of steel workers, carpenters and concrete workers is generally the building area divided by 15 ~ 20.
It depends.
