Who can know the proportion of the building multi-storey building materials, steel, cement, red brick, sand and the percentage of each.
According to a large number of statistics, the amount of building materials used in China according to the nature of their buildings are as follows: ordinary residential building concrete and steel consumption: . multi-storey masonry residential: steel 30kg / m2 concrete 0.3-0.33m3 / m. reinforced 38-42kg / m2 concrete 0.33-0.35m3 / m. high-rise 11-12 layers of reinforced 50-52kg / m2 concrete 0.35m3 / m. high-rise 17-18 layers of reinforced 54-60kg / m2 concrete 0.36m3 / m. senior 30 layer H = 94 meters steel 65-75kg / m2 concrete 0.42-0.47m3 / m. high-rise hotel apartment 28 layer H = 90 meters steel 65-70kg / m2 concrete 0.38-0.42m3 / m. villa concrete and steel an amount between residential and high-rise multi-story masonry above 7 degrees seismic data by district rules of structural design (two), ordinary multi-storey residential building construction budget and economic indicators . outdoor doors and windows (not including unit door between 11-12 layers, anti-theft The area occupied by the building area of ??0.20-0.. the template area of ??the building area of ??2.2 or so . outdoor plaster area of ??the building area of ??0.4 or so . the indoor plaster area of ??the building area of ??3.8 (four), the basic data . m. weight per linear meter of reinforced 0. * d * d. sand dry weight 1500kg / m. greensand An amount of 1700kg / m. gravel weight 2200kg / m. about one cubic meter brick 525 (partial thickness of the wall) . one cubic meter of about 175 hollow bricks . the screen one side and clean sand for an ordinary sand 1.3
. steel: 40 ~ 75KG / square meter (multi-layer content is low, high-level content is higher), the cost of real estate construction (according to the building square meter) . pile engineering (if any): 70 ~ 100 yuan / . concrete: 0.3 ~ 0.5 cubic meters / square meters (low content of the multi-layer, high-level high), together 100 ~ 165 yuan / square meter; . masonry works: 60 . plastering works: 25 to 40 yuan / square meter; . external wall works (including insulation): 50 ~ 100 yuan / square meter (high temperature; (Including fire as the standard), such as stone or curtain wall, it may be as high as 300 ~ 1000 yuan / square meter; . indoor water and electricity installation works (including fire): 60 ~ 120 yuan / square meter (according to cell grade, . doors and windows project (not included in the door): per square meter of building area of ??the doors and windows area of ??about (the higher than the high-level, high-level low); . 0.25 ~ 0.5 square meters (with the design and whether the high-grade great relationship, the proportion of high-end large), the cost of 90 to 300 yuan / square meter, generally 90 to 150 yuan / square meters, such as . earth, into the door, flue and public parts of the decoration works: 30 to 150 yuan / square meter (10 yuan / square feet, flue and public parts decoration works: 30 ~ 150 yuan / square meter And the level of high and low level of the relationship between the higher grade, the higher the cost);
This depends mainly on the strength of the purchase requirements, some parts only brick on the line
