我国建筑节能的“新”希望离不开建筑节能技术、产品和材料的创新。轻快好省:装配式方钢管混凝土建筑体系装配式轻型方钢管混凝土建筑体系不但可减轻用钢量、减轻混凝土用量,还能提高施工效率。钢管混凝土结构与H钢柱相比可节约用钢量50%,比单独空钢管柱与混凝土柱承载力之和大30%~50%。高层建筑如采用钢 China’s building energy-saving “new” hope can not be separated from building energy-saving technologies, products and materials innovation. Light and good province: Assembled square steel tube concrete building system Assembled light square steel tube concrete building system can not only reduce the amount of steel, reduce the amount of concrete, but also improve the construction efficiency. The concrete filled steel tubular structure can save 50% of the amount of steel compared with the H steel column, which is 30% -50% larger than the sum of the bearing capacity of the single hollow steel column and the concrete column. High-rise buildings such as steel
