轻钢龙骨墙体经济性研究

ECONOMIC RESEARCH ON LIGHT GAUGE STEEL-FRAMED RESIDENTIAL CONSTRUCTION COMPOSITE WALLS

采用黑龙江省相关定额作为计价依据,进行了轻钢龙骨复合墙体价格组成分析。为使轻钢龙骨复合墙体满足哈尔滨地区建筑外墙节能标准,依据保温性能相近原则,进行了轻钢龙骨墙体与8种常用墙体的造价、自重和占用空间对比分析。分析表明,轻钢龙骨复合墙体的价格在100～180元/m2之间,其中材料价格组成中岩棉所占比重最大,占总价格的40%～50%;龙骨腹板开孔后墙体材料价格升高0.4%～0.5%,加20mm厚苯板外保温后墙体材料价格升高13%～20%。对比分析表明,轻钢龙骨墙体具有保温性能优越、价格适中、墙体厚度小等特点,综合效益突出,具有在哈尔滨地区推广使用的前景。

Using the relevant estimate in Heilongjiang Province as the basic price,the price composition analysis of light gauge steel-framed composite wall has been carried on.To make the light gauge steel-framed composite wall meet construction outer wall energy conservation standard in Harbin area,according to the close principle of the heat preservation performance,a contrast analysis was done among the cost,self weight and occupied space of the light gauge steel-framed composite wall and the other eight kinds of commonly used walls.The rsults showed that of the price of light gauge steel-framed composite wall between in 100~180 yuan per square meter,of which material price of rock cotton was 40%~50% of total price.After adding slots to the web plate of stud in light gauge steel-framed composited wall,the material price of the wall was elevated by about 0.4%~0.5%,adding the 20 mm benzene board in the outside of the wall,the material price of the wall was raised by about 13%~20%.The contrast analysis indicated that the light gauge steel-framed composite wall has many characteristics such as the superior heat preservation performance,middle price and less thickness of the wall and so on,the comprehensive benefit is prominent,which is worth promoting in Harbin area.
