Construction method of large multi-span self-propelled automatic formwork
The invention discloses a construction method of a large multi-span self-propelled automatic formwork. According to the technical scheme, the construction method is characterized by comprising the steps of splicing of multiple sections of Bailey pieces, pouring of stand columns, installation of vertical supports, installation of unloading blocks, installation of cross beams, installation of Bailey beams and supporting frames, installation of distribution beams, installation of inclined supports, installation of bottom formworks and side formworks, prepressing of a support system, formwork descending, formwork dismantling, forward movement of a steel truss and dismantling of a steel structure below the steel truss. And entering the next section for construction and the like. The hydraulic jack and the unloading block are arranged on the hoop at the same time, so that the steel truss can be placed on the cross beam after descending, and the screw jack is arranged on the cross beam to jack up the steel truss so as to mount the longitudinal moving roller at the bottom of the steel truss; each span of the steel truss can be provided with a migration through pin or a carrying pole beam to fix a steel wire rope released by a winch, the steel truss can automatically slide after the box girder is poured, the construction procedure is greatly simplified, the construction period is greatly shortened, and the labor cost is reduced.
本发明公开了一种大型多跨自行式自动模架的施工方法，其技术方案的要点是该施工方法包括拼接多节贝雷片、立柱浇注、竖撑安装、卸落块安装、横梁安装、贝雷梁及支撑架安装、分配梁安装、斜撑安装、底模和侧模安装、支架体系预压、降模、拆模、钢桁架前移、拆除钢桁架以下的钢结构、进入下一节段施工等。本发明通过在抱箍上同时设置液压千斤顶和卸落块，使得能够将钢桁架下降后置于横梁上，通过在横梁上设置螺旋千斤顶顶起钢桁架以在钢桁架底部安装纵移滚筒，钢桁架的每一跨都可以安装迁移通销或扁担梁以固定卷扬机放出的钢丝绳，能够实现在箱梁浇注后自动滑移钢桁架，大大简化了施工工序，大大缩短工期，降低人工成本。
