Movable formwork suitable for pouring of large-span large-size concrete cross beam and construction method of movable formwork
The invention discloses a movable formwork suitable for pouring of a large-span large-size concrete cross beam and a construction method thereof.The movable formwork comprises support systems arranged on the two sides of a pier column, supports for supporting are arranged at the upper ends of the support systems, and main steel trussed beams are arranged on the supports; a steel formwork used for pouring a concrete cross beam is arranged on the main steel truss girder. The device is novel and reasonable in structural design, can meet the requirement that the normal operation of the existing line is not affected when the existing line crosses a plurality of tracks, and can meet the pouring requirement of an ultra-large-size concrete cross beam. According to the method, the steel consumption is small, hoisting and dismounting are easy, the construction process is safe, and pouring of the large-size concrete cross beam is completed on the premise that less steel is used, construction is more convenient, and the safety coefficient is higher. The safety coefficient is high, construction can be conducted without entering the existing line in the construction process, cross transportation of the existing line is completely not affected, all installation, disassembly, transportation and construction are completed outside the existing line, and the safety of the existing line can be well guaranteed.
本发明公开了一种适用于大跨度大体积混凝土横梁浇筑的移动模架及其施工方法，移动模架包括设置在墩柱两侧的支架体系，所述支架体系上端设置有支撑用的支座，所述支座上设置有主钢桁梁，所述主钢桁梁上设置有用于浇筑混凝土横梁的钢模板。本发明的结构设计新颖合理，既能满足跨越多股道既有线不影响既有线的正常运营又能满足超大体积混凝土横梁的浇筑要求。本发明的用钢量少，吊装和拆卸简单，施工过程安全，用更少的钢材，更方便的施工和更高的安全系数的前提下完成大体积混凝土横梁的浇筑。本发明的安全系数高在施工过程中不需要进入既有线能进行施工，与既有线的交叉运输完全没有影响，一切安装、拆卸、运输、施工均在既有线外部完成，能很好保证既有线的安全。
