Large-span complex steel structure roof structure and construction method
The invention relates to a large-span complex steel structure roof structure and a construction method, and the construction method comprises the following steps: dividing an elevated layer into an area A and an area B, firstly pouring concrete in the area A, and then pouring concrete in the area B; after the concrete strength of the area A reaches the standard, part of truss structures of the area A are assembled; after the concrete strength of the area B can bear the hoisting operation, the remaining truss structure of the area A is assembled and connected with the part of the truss structure which is firstly assembled into a whole; after the concrete strength of the area B reaches the standard, a temporary lifting structure is installed, an area B truss structure is assembled, and after assembling is completed, the area B truss structure is connected with the area A truss structure to form a truss structure; a truss structure tensioning device is installed, the truss structure is lifted through the lifting column and the temporary lifting structure, meanwhile, the truss structure is tensioned, and after the truss structure is lifted to the preset height, the truss structure is connected with the lifting column; and mounting a cantilever structure below the truss structure. The construction period can be effectively shortened, and the construction efficiency and the truss structure assembling precision are high.
本申请涉及一种大跨复杂钢结构屋盖结构及施工方法，所述施工方法包括如下步骤：将高架层划分为A区和B区，先浇筑A区混凝土再浇筑B区混凝土；A区混凝土强度达标后，拼装A区部分桁架结构；B区混凝土强度能够承受吊装作业后，拼装A区剩余桁架结构，并与先拼装的部分桁架结构连接成整体；B区混凝土强度达标后，安装临时提升结构并拼装B区桁架结构，拼装完成后与A区桁架结构连接形成桁架结构；安装桁架结构张拉装置，通过提升柱和临时提升结构提升桁架结构同时对桁架结构进行张拉，提升至预定高度后，将桁架结构与提升柱连接；安装桁架结构下方悬挑结构。本发明能够有效缩短施工工期，施工效率和桁架结构拼装精度高。
