Installation device and installation method of large-span string truss structure
The invention discloses an installation device and installation method of a large-span truss string structure, and the installation device of the large-span truss string structure comprises a sliding rail which comprises a linear sliding guide section and a slope sliding guide section. The slope sliding guide section is suitable for guiding the spliced truss unit to slide downwards gently to be separated from the sliding track, the slope sliding guide section comprises a separating end and a connecting end which are arranged oppositely, the connecting end is connected with the linear sliding guide section, the spliced truss unit is separated from the sliding track from the separating end, and the spliced truss unit slides along the sliding track as a whole. Due to the fact that the slope sliding guide section can guide the spliced truss unit to be slowly and downwards separated from the sliding rail, the situation that the spliced truss unit generates a large elevation difference before and after derailing due to large acceleration and cracks are generated in butt welding seams can be avoided, it is guaranteed that the elevation of the truss structure meets the design requirement, subsequent installation of a metal roof is facilitated, and the construction efficiency is improved. And the construction safety and the construction quality are ensured.
本发明公开了一种大跨度张弦桁架结构的安装装置及安装方法，大跨度张弦桁架结构的安装装置包括包括滑移轨道，滑移轨道包括直线滑移引导段以及坡面滑移引导段，坡面滑移引导段适于引导拼接桁架单元平缓向下滑动脱离滑移轨道，坡面滑移引导段包括相对设置的脱离端以及连接端，连接端与直线滑移引导段相连，拼接桁架单元从脱离端脱离滑移轨道，拼接桁架单元作为一个整体沿滑移轨道滑动。由于坡面滑移引导段可引导拼接桁架单元平缓向下脱离滑移轨道，因此，可避免较大的加速度导致的拼接桁架单元在脱轨前后产生较大的标高差、以及使对接焊缝产生裂纹，保证桁架结构的标高满足设计要求，便于后续金属屋面的安装，保证施工安全和施工质量。
