高层建筑结构形式多以框架结构为主,其砼现浇量大。砼浇注是控制和影响工程主体施工工期重要工序。其模板架立占钢筋砼工作量30%左右,占主体工期50%,因此模板方案选择是制约砼浇注关键工序。长春建工集团第三建筑公司1993年引进了北京北新SP—70早拆模板体系,解决了模板的快速周转问题,提高了砼表面质量,加速了施工进度,提高工效。
The structure of high-rise buildings is mostly based on the framework structure, and the volume of concrete structures is high.砼 Casting is an important process for controlling and influencing the main construction period of the project. The template stands for about 30% of the work load of the reinforced concrete, and it accounts for 50% of the main construction period. Therefore, the choice of the template scheme is the key process to control concrete pouring. The third construction company of Changchun Construction Engineering Group introduced the Beijing Beixin SP-70 early demolition formwork system in 1993, which solved the problem of quick turnover of the formwork, improved the surface quality of the concrete, accelerated the construction progress, and improved the work efficiency.
