Construction method of triangular truss cantilever formwork system
The invention provides a construction method of a triangular truss cantilever formwork system. The construction method comprises the following steps that embedded parts are placed, U-shaped rings are pre-embedded, diagonal bars are welded, cantilever steel beams are mounted, the cantilever steel beams are fixed, hard sealing on battens is performed, steel wire ropes are pulled obliquely, a scaffold is erected and the like. According to the construction method of the triangular truss cantilever formwork system, a triangular truss is connected with a building main body through welding, fixed connection and the like to serve as a corridor formwork full framing supporting point, the scaffold is erected above the triangular truss for construction, meanwhile, the tension of a steel wire rope is detected in real time, overload early warning is conducted on the triangular truss in a lamplight early warning mode, risks caused by the overload problem are avoided. The safety of the structure and a frame body is guaranteed, the cantilever steel beams are short in installation period and can be recycled, the construction period is shortened, the construction cost is reduced, and the problems that an existing high-altitude large-span cantilever concrete member formwork supporting system is large in risk and difficult to construct are solved.
本发明提供了三角桁架悬挑模板体系施工方法，包括：放置预埋件、预埋U型环、斜撑杆焊接、安装悬挑钢梁、固定悬挑钢梁、条板硬封、斜拉钢丝绳、脚手架搭设等步骤，本三角桁架悬挑模板体系施工方法，通过采用三角形桁架与建筑主体通过焊接、固接等方式进行连接，作为连廊模板满堂架支撑点，在上方搭设脚手架进行施工，同时实时检测钢丝绳的拉力，通过灯光预警的方式对三角形桁架进行过载预警，规避了因过载问题带来的风险，保证了结构与架体安全，悬挑钢梁安装周期较短，可周转使用，有利于缩短施工周期，降低施工成本，解决了目前高空大跨度悬挑混凝土构件模板支撑体系存在的风险大、施工难的问题。
