Reverse construction method of single-layer flat plate latticed shell roof structure
The invention discloses a reverse construction method of a single-layer flat plate latticed shell roof structure. The reverse construction method comprises the steps that a temporary lifting support is installed; a latticed shell roof is assembled on the ground according to a drawing; the assembled latticed shell roof is tried to be lifted; the latticed shell roof is lifted to a design position; connecting rod pieces are embedded and supplemented in the high altitude, and a lower shear wall is constructed; beam members between the shear wall and columns and other beam members are connected; the temporary lifting support is unloaded; and lower floor members are connected. According to the reverse construction method, a triangular lattice system is formed through the structural columns and the lifting support, and the influence of the single-layer latticed shell roof reverse construction forming process on the design use stage can be reduced; temporary horizontal connecting rods are arranged on the lifting support, horizontal connecting rods are arranged below the latticed shell roof, the temporary horizontal connecting rods are disassembled, and therefore the stability of the latticed shell roof lifting process and the lateral stiffness of the latticed shell roof structure and the lifting support are guaranteed; and then a symmetrical batch unloading mode is adopted, and therefore the overall lateral stiffness of the structure is guaranteed, and the safety and controllability of the construction process are guaranteed.
本发明公开了一种单层平板网壳屋盖结构的逆作施工方法，包括：安装临时提升支架；根据图纸在地面拼装网壳屋盖；试提升拼装好的网壳屋盖；提升网壳屋盖至设计位置；高空嵌补连接杆件，施工下部剪力墙；连接剪力墙与柱间的梁构件及其余梁构件；卸载临时提升支架；连接下部楼层构件；本发明其通过结构柱与提升支架形成三角格构体系，可以减少单层网壳屋盖逆作施工成型过程对设计使用阶段的影响；通过在提升支架上设置临时水平联系杆，在网壳屋盖下方设置水平联系杆，并拆除临时水平联系杆，保证网壳屋盖提升过程的稳定以及网壳屋盖结构、提升支架的抗侧刚度；再采用对称分批卸载的方式，保证结构整体的抗侧刚度，确保施工过程安全可控。
