Steel truss lifting construction method
The invention discloses a steel truss lifting construction method which comprises the following steps: S1, carrying out in-situ splicing on a steel truss at a middle position at a secondary elevation layer, and carrying out primary lifting on the steel truss after the splicing is completed, S2, splicing the steel trusses on the east and west sides of the middle layer, and then butting and fixing the lifted steel truss at the middle position and the steel trusses on the two sides into a whole, s3, the fixing effect of the steel truss in the S2 is checked, and then the whole steel truss is lifted to a set elevation layer for the second time; according to the steel truss lifting construction method, after the secondary elevation layer is assembled, the steel trusses are lifted for the first time, the steel trusses on the east side and the west side of the station entering layer are assembled, then the whole steel trusses are lifted for the second time to the set elevation layer, and the problem that in the lifting process of an existing lifting mode, the lifting efficiency is high is solved. The problems that the workload of conventional high-altitude assembling and welding is large, a large number of supporting jig frames are needed in the construction process, large-specification hoisting equipment is further needed, and the construction cost is high are solved.
本发明公开了一种钢桁架提升施工方法，包括S1：于次标高层对中间位置钢桁架进行原位拼装，拼装完成后对钢桁架进行一次提升，S2：拼装中间层位于东西两侧的钢桁架，再将提升的中间位置钢桁架与两侧钢桁架对接并固定为一个整体，S3：检查S2钢桁架的固定效果，之后对整体进行二次提升至设定标高层；该钢桁架提升施工方法，通过次标高层拼装完成后对钢桁架进行一次提升，拼装进站层东西两侧的钢桁架，之后对整体钢桁架进行二次提升至设定标高层，解决了现有的提升方式对其进行提升过程中，常规的高空组装和焊接的工作量比较大，施工过程中需要大量的支撑胎架，还需要较大规格的吊装设备，使得施工成本比较高的问题。
