Construction method for stably erecting bridge precast beam slab
The invention belongs to the technical field of bridge precast beam slab erection, and particularly discloses a construction method for stably erecting a bridge precast beam slab, which comprises the following steps: forming a raised support table at the top of a sand box type temporary support by pouring concrete; a guide steel column is pre-buried in the top of the supporting table in the width direction of the precast beam plate; guide grooves are reserved in the two ends of the bottom of the precast beam plate, and positioning grooves corresponding to the supporting tables in position are formed in the two ends of the bottom of the precast beam plate; a limiting block extending downwards is arranged at the bottom of the precast beam plate along the end, away from the guide groove, of the positioning groove, and an inserting groove allowing the limiting block to be inserted in is reserved in the top of the sand box type temporary support. By means of the arched curved surface structures of the guide steel columns, on one hand, the two ends of the precast beam plate can be conveniently positioned when the precast beam plate is placed, on the other hand, the precast beam plate is guided during transverse movement, transverse movement friction force is reduced, it is guaranteed that the precast beam plate is accurately and rapidly positioned, meanwhile, the situation of position deviation is not prone to occurring in the follow-up process, and stability is good.
本发明属于桥梁预制梁板架设技术领域，具体公开了一种桥梁预制梁板稳定架设的施工方法，包括在砂箱式临时支座的顶部通过灌注混凝土形成凸起的支撑台；在支撑台顶部沿预制梁板宽度方向预埋一根导向钢柱；在预制梁板底部两端预留有导向槽，在预制梁板底部两端开设有与支撑台位置对应的定位槽；在预制梁板底部沿定位槽远离导向槽的一端设置有向下延伸的限位块，在砂箱式临时支座的顶部预留有供限位块插入的插槽。本发明利用导向钢柱的拱起的曲面结构，一方面便于预制梁板在放置时对其两端进行定位，另一方面在横移时对预制梁板进行导向，且减小横移的摩擦力，保证预制梁板精准快速定位的同时，后续不易出现位置偏移的情况，稳定性好。
