砖混大模板结构是在北京“前三门”统建工程大模板建筑的基础上发展起来的。实践证明,大模板施工新工艺,是墙体改革的一条重要途径.是改变建筑业手工操作,提高机械化、装配化程度,加快施工进度,减轻劳动强度,改善劳动条件的一项有力措施。前三门大模板建筑都是外板内模(外墙为预制壁板,内墙为大模板现浇混凝土)的高层住宅。造价较高,水泥、钢材耗用较多。同时,目前要全面推行高层建筑也有一定困难。七七年初,公司党委提出了要在多
The brick-concrete large formwork structure was developed on the basis of a large formwork construction of the “first three doors” of Beijing’s unified construction project. Practice has proved that the new formwork construction new process is an important way for the reform of the wall. It is a powerful measure to change the manual operation of the construction industry, increase the degree of mechanization and assembly, speed up the construction progress, reduce labor intensity and improve working conditions. The first three large formwork buildings are high-rise residential buildings with inner plates (exterior walls are prefabricated and inner walls are cast-in-place concrete). Higher cost, more consumption of cement and steel. At the same time, it is also difficult to fully implement high-rise buildings. In early July of 2007, the company’s party committee proposed
