Reverse construction method bottom plate well hole form erecting method
The invention provides a reverse construction method bottom plate well hole form erecting method. The method comprises the following steps that a bottom plate well hole is formed by binding bottom plate reinforcing steel bars; well hole forms are arranged in the bottom plate well hole and comprise a bottom form and a plurality of vertical forms, the bottom form and the plurality of vertical formsare arranged at the bottom and the periphery of the bottom plate well hole respectively, a plurality of longitudinal battens are arranged on the side, away from bottom plate reinforcing steel bars, ofthe bottom form at intervals, a plurality of vertical battens are arranged on the sides, away from the bottom plate reinforcing steel bars, of the vertical forms at intervals correspondingly, a supporting frame is arranged in the bottom plate well hole, the bottom of the supporting frame is arranged on the longitudinal battens of the well hole forms, and the top of the supporting frame is supported on the bottom surface of an upper-layer structure beam plate constructed in advance through a reverse construction method through an adjustable jacking. According to the method, the supporting frame of the well hole forms of the lower portion is supported by the upper-layer structure beam plate constructed by the reverse construction method, the problems that deep pit form hoisting in reverse construction is large in heavy object carrying difficulty and large in heavy object counter pressure hidden danger are solved, and labor force and cost are saved.
本发明提供一种逆作法底板井洞支模方法，通过底板钢筋绑扎形成底板井洞；在底板井洞内设置井洞模板，井洞模板包括底部模板及若干竖向模板，底部模板以及若干竖向模板分别设置于底板井洞的底部以及四周，底部模板上远离底板钢筋的那一侧间隔设有若干纵向木方，竖向模板上远离底板钢筋的那一侧分别间隔设有若干竖向木方；在底板井洞内设置支撑架，所述支撑架的底部设置于所述井洞模板内的纵向木方上，所述支撑架的顶部通过可调顶托支撑于通过逆作法先行施工的上层结构梁板的底面上，其利用逆作法已施工完成的上层结构梁板支撑下方井洞模板的支撑架，解决逆作施工深坑吊模重物搬运难度大、重物反压隐患多的问题，节约劳动力与成本。
