Large-span composite string truss hoisting construction method under working condition of limited space
The invention discloses a hoisting construction method for a large-span composite string truss under the working condition of limited space, and belongs to the technical field of building construction. The method comprises the steps that according to the width of a jig frame, two ground assembling jig frame sets are arranged in the length direction of a building, and a composite string truss is assembled on the ground assembling jig frame sets; hoisting is started after assembly is completed, and one composite string truss is hoisted each time; after the composite string trusses on one ground assembling jig frame group are hoisted, the ground assembling jig frame group is moved to the outer edge of the building, the composite string trusses start to be assembled on the ground assembling jig frame group, and meanwhile, the composite string trusses on the other ground assembling jig frame group continue to be hoisted; and after the other group of composite string trusses is hoisted, hoisting two trusses of composite string trusses on the outer edge of the building. According to the method, ground operation space and hoisting equipment are fully utilized, the splicing precision of the truss is guaranteed by adopting a whole truss hoisting mode, the construction progress is accelerated, and the high-altitude operation risk is reduced.
本发明公开了空间受限工况下大跨度复合张弦桁架吊装施工方法，属于建筑施工技术领域。本发明的方法包括：根据胎架宽度并沿建筑长度方向设置2组地面拼装胎架组并在其上拼装复合张弦桁架；拼装完成后开始吊装，每次吊装一榀复合张弦桁架；吊装完一组地面拼装胎架组上的复合张弦桁架后，将该组地面拼装胎架组移至建筑外沿并开始在其上拼装复合张弦桁架，同时继续吊装另外一组地面拼装胎架组上的复合张弦桁架；另外一组复合张弦桁架吊装完成后，接着吊装建筑外沿的2榀复合张弦桁架，即可。本发明方法充分利用地面操作空间和吊装设备，采用整榀桁架吊装的方式保障桁架的拼装精度、加快施工进度，降低高空作业风险。
