北京西客站北站房Ⅰ段主楼工程地下为一～二层,地上为一～十三层,楼板约4万m~2为双向密肋楼板体系,均采用塑料模壳作为楼层模板,根据不同开间、不同进深和不同楼板厚度分块组合,双向密肋楼板网格布置分为80余种,模壳为三种型号,即1200mm×1200mm×300mm,1200mm×1200mm×400mm,1200mm×900mm×300mm。其中凡使用300mm高模壳的肋梁底宽为50mm,使用400mm高模壳的肋梁底宽为150mm。由于使用面积大,平面网格组成形式多,施工工期紧,资金紧缺。既要使用先进工具,又要解决模壳少而
Beijing West Railway Station North Railway Station Section I main building underground is one to two floors, one to thirteen floors above the ground, floor about 40,000 m~2 is a two-way ribbed floor system, all adopt plastic mold shell as floor template, according to different There are more than 80 kinds of double-sided ribbed floor grids arranged in bays, different depths and different floor thicknesses. There are three types of mouldings, namely 1200mm×1200mm×300mm, 1200mm×1200mm×400mm, 1200mm×900mm×300mm. . Wherein, the bottom width of a rib beam with a 300mm high formwork shell is 50mm, and the bottom width of a rib beam with a 400mm high formwork shell is 150mm. Due to the large area of use, the planar grid forms many forms, the construction period is tight, and funding is scarce. It is necessary to use advanced tools, but also to solve the problem of less mold and shell
