Rapid installation method of high-rise steel structure truss roof
The invention discloses a rapid installation method of a high-rise steel structure truss roof, and belongs to the technical field of high-altitude steel structure installation. A tubular steel truss structure of the high-rise steel structure truss roof is completely formed by splicing and welding steel rod pieces and joints on a ground temporary supporting frame, a steel rail is installed on a constructed concrete roof truss beam, through a double-machine-platform crane, field hoisting requirement is met, then a steel truss is hoisted to a preset elevation position, alignment is carried out, then the steel truss slides to a designed position in parallel through a traction device, and finally is assembled, welded and filled in the air at high altitude through a tower crane, and the overallinstallation of the roof steel truss is completed. According to the rapid installation method of the high-rise steel structure truss roof, installation is adapted to local conditions, overall layout can be carried out by combining on-site temporary building facilities, a large steel truss assembling and hardening site is not needed, the assembling and welding time of the whole truss is saved, manpower resources are reasonably organized, beat line production construction is adopted, the construction difficulty and safety risks generated by overall hoisting of the roof steel truss are greatly reduced, the construction period is shortened, and the construction safety is ensured.
本发明公开了一种高层钢结构桁架屋盖的快速安装方法，属于高空钢结构安装技术领域，其管状钢桁架结构全部由钢杆件和节点在地面临时支撑架上进行拼装焊接，并在已施工完成混凝土屋架梁上安装钢质轨道，通过双机台吊使其满足现场起吊要求，进而吊装至预定标高位置，进行找正，然后通过牵引装置平行滑移至设计位置，最终通过塔吊高空拼装焊接填空，完成屋面钢桁架整体安装。该方法安装因地制宜、可结合现场临建设施整体进行布局，无需较大的钢桁架拼装硬化场地、节省整片桁架拼装、焊接时间，合理组织人力资源采用分节拍流水作业施工，大大降低了屋面钢桁架整体吊装产生的施工难度及安全风险，缩短了施工工期，保证施工的安全性。
