The invention discloses a tower crane support system for variable cross-section structure space, which comprises a main beam, a first turnover beam, a second turnover beam, a first wall-attached support and a second wall-attached support, the two ends of the main beam are respectively connected with the first turnover beam and the second turnover beam, the first turnover beam is connected with the first wall-attached support, and the second turnover beam is connected with the second wall-attached support. And the second overturning beam is connected with the second wall-attached support. The tower crane supporting system has the beneficial effects that the main beam is designed in a sectional mode, the middle section beam is dismantled to form the tower crane supporting system matched with different types of variable cross-section structure spaces, the application range of the tower crane supporting system is expanded, the overturning beam is overturned downwards to shorten the beam length to cross over the wall-attached support, then the overturning beam is overturned upwards to restore the beam length, and therefore the construction efficiency is improved. The supporting beam is located to the wall-attached support to be locked, construction is easy and convenient, the construction technology of the tower crane supporting system is optimized, the construction period is shortened, the climbing construction cost of the tower crane is saved, the reinforcing rib plates are arranged at the connecting positions of the main beams, the multiple positioning pins are arranged, and the safety and reliability of the construction process are guaranteed.
本发明公开了一种用于变截面结构空间的塔机支撑系统,包括主梁、第一翻转梁、第二翻转梁、第一附墙支座和第二附墙支座,主梁的两端分别连接于第一翻转梁和第二翻转梁,第一翻转梁与第一附墙支座连接,第二翻转梁与第二附墙支座连接。本发明有益效果:本发明的主梁分段式设计,通过拆除中段梁形成与不同类型变截面结构空间相匹配的塔机支撑系统,拓展了塔机支撑体系的适用范围,翻转梁向下翻转以缩短梁长越过附墙支座,然后向上翻转以恢复梁长,并将支撑梁落座至附墙支座锁紧,施工简便,优化了塔机支撑体系施工工艺,缩短了施工工期,节约塔机爬升施工成本,主梁连接处均设置有加强肋板,定位销均设置有多个,保证施工过程的安全性和可靠性。
