Construction method for overall low-position splicing and lifting installation of upward moving formwork
The invention discloses a construction method for overall low-position splicing and lifting installation of an ascending type movable formwork. A main beam, a nose bridge, an upper cross beam and a transverse moving system of the ascending type movable formwork are spliced at the root of a pier column, and the ascending type movable formwork which is locally spliced is formed; after the locally-assembled ascending type movable formwork is lifted to a preset height for the first time, a lower hanging beam and a formwork system of the ascending type movable formwork are assembled, and a completely-assembled ascending type movable formwork is formed; after the completely-assembled ascending type movable formwork is lifted to the pier top for the second time, the ascending type movable formwork is taken down to prepare for bridge assembling; and a dual-function supporting leg structure is arranged at the top of the pier column and used for achieving the first-time lifting, the second-time lifting and the falling. According to the method, the assembly links of all the structures of the ascending type movable formwork are completed at the low position and the middle position below the pier column, then overall lifting in-place falling is conducted, and the risk generated by high-altitude assembly in the prior art is effectively reduced or even avoided.
本申请公开一种上行式移动模架整体低位拼装与提升安装的施工方法：在墩柱根部拼装上行式移动模架的主梁、鼻梁、上横梁和横移系统，形成局部拼装的上行式移动模架；对所述局部拼装的上行式移动模架进行第一次提升到达预设高度之后，拼装上行式移动模架的下挂梁和模板系统，形成完整拼装的上行式移动模架；对所述完整拼装的上行式移动模架进行第二次提升到达墩顶之后，落架以准备进行桥梁拼装；在墩柱顶部设置双功能支腿结构，用于实现所述第一次提升、第二次提升和落架。本申请的方法，将上行式移动模架各个结构的拼装环节在墩柱以下的低位和中位完成，再进行整体提升到位落架，有效降低甚至避免现有技术中高空拼装产生的风险。
