Installation method of underground two-layer assembly type prestressed section steel combined support
The invention discloses a mounting method of an underground two-layer fabricated prestressed profile steel combined support, and relates to the technical field of constructional engineering. The construction method comprises the steps of construction preparation, positioning and paying off, top beam and embedded part installation, profile steel stand column construction, first-layer supporting bracket and supporting beam installation, first-layer combined support splayed support installation, first-layer combined support opposite support installation, first-layer combined support prestress application, earth excavation to a second-layer supporting working face and second-layer combined support bracket construction. Mounting two-layer combined support enclosing purlins; mounting two-layer brackets and supporting beams; mounting two-layer combined support opposite supports; applying prestress to the two-layer combined supports; high-strength bolts are adopted for connection on the whole, mounting and dismounting are convenient and fast, the combined support can be basically recycled, materials are turned over, the project manufacturing cost is reduced, components are standardized, construction can be more accurate, meanwhile, the construction speed is guaranteed, and the construction quality is better controlled.
本发明公开了一种地下两层装配式预应力型钢组合支撑的安装方法，涉及建筑工程技术领域，本发明包括：施工准备、定位放线、冠梁与预埋件安装、型钢立柱施工、一层支撑托座与支撑梁安装、一层组合支撑八字撑安装、一层组合支撑对撑安装、一层组合支撑预应力施加、土方开挖至第二层支撑工作面、二层组合支撑牛腿施工、二层组合支撑围檩安装、二层托座与支撑梁安装、二层组合撑对撑安装、二层组合撑预应力施加、各构件达到设计强度以及预应力型钢组合式支撑的拆除。本发明整体采用高强螺栓连接，安装与拆除便捷，组合支撑基本可以回收，材料周转，项目造价成本降低，构件标准化，能更加精确施工，同时保证其施工速度，更好的控制施工质量。
