Inclined hollow pier top cover plate top sealing construction bottom formwork and method
The invention discloses an inclined hollow pier top cover plate top sealing construction bottom formwork and method, and relates to the field of bridge construction application, a plurality of bottom formworks are prefabricated, and lifting lug steel bars, temporary anchoring steel bars and permanent anchoring steel bars are reserved on the bottom formworks. And the suspension system is arranged on the pier body. And the hoisting lug steel bars of the multiple bottom formworks are connected through a suspension system, and the multiple bottom formworks are hoisted into the pier body. And the temporary anchoring steel bars of the multiple bottom formworks are connected through the suspender assemblies, and the multiple bottom formworks are fixed into the pier body of the oblique hollow pier. And cover plate steel bars of the pier top cover plate are bound on the multiple bottom formworks, and all the permanent anchoring steel bars are bound together with the cover plate steel bars. And after the pier top cover plate is poured, the suspender assemblies and the temporary anchoring steel bars are disassembled, and post-treatment is conducted on the pier top cover plate. According to the method, the bottom formwork made of the reinforced concrete is preset and hoisted on site, so that the construction process is simplified, the construction cost is reduced, and the utilization rate of the bottom formwork is increased.
本发明公开了一种斜向空心墩墩顶盖板封顶施工底模板及方法，涉及桥梁施工应用领域，包括预制多个底模板，并在底模板上预留起吊吊耳钢筋、临时锚固钢筋、及永久锚固钢筋。将悬吊系统置于墩身上。利用悬吊系统连接多个底模板的起吊吊耳钢筋，将多个底模板吊装至墩身内部。利用吊杆组件连接多个底模板的临时锚固钢筋，将多个底模板固定在斜向空心墩的墩身内部。在多个底模板上绑扎墩顶盖板的盖板钢筋，并将所有永久锚固钢筋分别与盖板钢筋绑扎在一起。浇筑墩顶盖板后将吊杆组件和临时锚固钢筋拆开，对墩顶盖板进行后期处理。本发明通过预置钢筋混凝土材质的底模板，并进行现场吊装，简化施工流程，降低施工成本，提高底模板的利用率。
