Large multi-span self-propelled automatic formwork
According to the technical scheme, the large-scale multi-span self-propelled automatic formwork is characterized in that the large-scale multi-span self-propelled automatic formwork comprises a pre-embedded steel plate arranged on a stand column, a vertical support fixed to the pre-embedded steel plate, hoops arranged on the vertical support, a plurality of hydraulic jacks and a plurality of unloading blocks arranged on each hoop, and a cross beam arranged on the unloading blocks; the cross beam is erected in the transverse direction of the viaduct, inclined struts are arranged on hoops on the two outer sides of the viaduct, and a steel truss capable of sliding to the next link after formwork descending is arranged on the cross beam. 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，其技术方案的要点是包括有设在立柱上的预埋钢板、固定在预埋钢板上的竖撑，在竖撑上设有抱箍，在每个所述抱箍上设有多个液压千斤顶和多个卸落块，在卸落块上设有横梁，横梁沿高架桥的横向架设，在高架桥两外侧的抱箍上设有斜撑，在横梁上设有降模后能够滑移至下一联的钢桁架。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。
