Roof steel structure reconstruction method
The invention relates to the technical field of building construction, in particular to a roof steel structure reconstruction method, which comprises the following steps: firstly, erecting a construction platform, arranging an upper support on the construction platform for supporting the existing roof steel structure, respectively dismantling the existing roof and the existing roof steel structure, reinforcing concrete column heads, pre-burying sliding supports, and adjusting the position of the upper support. And then the new roof steel structure, the accessory structure and the new roof are installed, and the construction platform is dismantled. According to the reconstruction method, the defect of reconstruction of an existing large-span truss structure roof is overcome, effective connection of dismantling of an existing roof steel structure and installing of a new roof steel structure is achieved according to the stress characteristics of a large-span truss structure system, and the construction efficiency is high.
本发明涉及建筑施工技术领域，尤其涉及一种屋面钢结构改建方法，首先搭设施工平台，在施工平台上设置上部支撑，用于支撑现有屋面钢结构，分别拆除现有屋面和现有屋面钢结构后，加固混凝土柱头并预埋滑动支座，调节上部支撑的位置，用于支撑新屋面钢结构，然后分别安装新屋面钢结构、附属结构及新屋面，拆除施工平台。该改建方法弥补了现有大跨度桁架结构屋面改造的缺失，针对大跨度桁架结构体系受力特点，实现了现有屋面钢结构的拆除和新屋面钢结构安装的有效衔接，且施工效率高。
