Film covering method for super-large-span steel structure plane truss
The invention discloses a film covering method for a super-large-span steel structure plane truss. According to the method, a film is stretched along a guide rail through traction, film covering is completed, anchoring is not needed, the efficiency is greatly improved, and the high-altitude operation risk is avoided; after the ultra-large-span steel structure plane truss is hoisted, the guide rails are distributed at equal intervals in the span direction of the steel structure plane truss; clamps for dragging and fixing are installed at two ends of the film, a dragging steel wire rope is wound from one end of the steel structure plane truss to the other end of the steel structure plane truss along the span direction of the steel structure plane truss, and the dragging steel wire rope is connected to the clamp at one end of the film; and one end, connected with the dragging steel wire rope, of the film penetrates through the guide rails in the direction of the guide rail, a winch is started to drag the dragging steel wire rope, the film is pulled out of the steel structure plane truss in the direction of the guide rail, then the dragging steel wire rope and the clamps are disconnected, the clamps at the two ends of the film are fixed to the bottom side of the steel structure plane truss, and then all the guide rails are coated with films in sequence.
本发明公开一种超大跨度钢结构平面桁架的覆膜方法，通过牵引将膜沿导轨拉伸，完成覆膜，无需锚固，不仅效率大幅提升，而且避免了高空作业风险；将超大跨度钢结构平面桁架完成吊装后所述导轨沿钢结构平面桁架的跨度方向等间距分布；并在膜的两端安装用于拖拽固定的夹具，将拖拽钢丝绳从钢结构平面桁架的一端沿钢结构平面桁架的跨度方向绕到钢结构平面桁架的另一端，并连接在膜一端的夹具上；将连接有拖拽钢丝绳的膜一端沿导轨方向，从导轨中穿进去，启动卷扬机对拖拽钢丝绳进行牵引，将膜沿导轨方向从钢结构平面桁架的跨上拉过去，然后拆开拖拽钢丝绳与夹具之间的连接，将膜两端的夹具固定在钢结构平面桁架底侧上，然后依次将所有导轨之间覆膜。
