长期以来,钢筋混凝土框架结构的非承重内隔墙仍沿用三孔砧双面粉刷老工艺。这样,不但墙体自重大,现场不文明,而且速度慢,不能满足快速施工的要求,特别是高层建筑框架结构完成以后尚要大量的砖与砂浆垂直运输与喷浆等设备,致使粉刷阶段工期与所耗劳动力大于结构作业。使用轻钢龙骨纸面石膏板作内隔墙,具有干作业特点, For a long time, the non-load-bearing internal partition wall of reinforced concrete frame structure still uses the old technology of three-hole anvil double-flour. In this way, not only the wall itself is heavy, the site is uncivilized, but also it is slow, and it cannot meet the requirements of rapid construction. In particular, after the completion of the high-rise building framework structure, a large number of equipment such as vertical transportation of bricks and mortar and shotcrete is still required, resulting in a period of whitewashing. With the consumption of labor is greater than structural operations. The use of light steel keel plasterboard as the internal partition has the characteristics of dry operation.
