首钢第二建筑工程公司在1号转运站工程上采用降模法施工结构的楼板效果良好。具体作法是利用原来的滑模施工时的两个施工区段的操作平台作为降模平台。每个施工区段面积约60平方米,分别支设楼层的主、次梁及楼板混凝土模板。主次梁仍采用悬索自承重梁的结构形式,主梁悬索筋支吊在框架梁上,混凝土浇灌后一昼夜(指北京夏季气温),即可降模,楼层混凝土的总重量由主梁承担。降模设施很简单,顶层施工时,利用提
Shougang No.2 Construction Engineering Co., Ltd. has achieved a good effect on the floor of the transfer station project using the drop molding method to construct the structure. The specific method is to use the operating platform of the two construction sections during the construction of the original sliding mold as a down-mold platform. Each construction section has an area of about 60 square meters, and the main, secondary beams and floor concrete templates of the floors are respectively provided. The primary and secondary beams still use the structure of the suspended self-supporting beam. The primary beam suspenders are suspended on the frame beam. After the concrete is watered for a whole day and night (referring to the summer temperature in Beijing), the mold can be lowered. The total weight of the floor concrete is determined by the main beam. bear. The drop molding facility is very simple.
