The invention discloses a device for integrally hoisting a roof purline. A combined structure of connecting section steel and ratchet claws is adopted, all components (purlines, pull rods and braces) of roof components are assembled into modules, the modular roof steel structure can be grasped through the ratchet claws, hoisting machinery can be connected through the connecting section steel, the working procedures of aloft work are greatly reduced, construction lifting appliance team and manpower are saved, the labor efficiency is improved, and the construction cost is reduced. The construction period is shortened. And the safety risk of high-altitude operation is greatly controlled. Meanwhile, a ratchet claw is adopted to replace a lifting lug, the principle of a tooth type one-way adjustable corner ratchet is utilized, and after the modular roof steel structure falls in place, the ratchet claw automatically loosens a hook. Constructors do not need to move to the purline at high altitude to take off the steel wire rope, so that the safety risk is greatly reduced, and the life of the constructors is well protected.
本申请公开了屋面檩条整体吊装的装置。采用连接型钢、棘轮抓组合结构,在对屋面构件各部件(檩条、拉杆、拉条)组装成模块形式,能够通过棘轮抓对模块化屋面钢结构进行抓持并通过连接型钢连接吊装机械,极大减少高空作业工序,节省施工吊具台班及人工,提高了劳动效率,缩短施工周期。高空作业安全风险得到很大控制。与此同时,本装置采取了棘轮抓代替了吊耳的形式,利用齿式单向可调转角棘轮原理,在模块化屋面钢结构落位后,棘轮抓自动松钩。施工人员无需在高空移动到檩条上进行摘钢丝绳作业,极大降低了安全风险,对施工人员生命起到很好的保护作用。
