High-toughness ultrathin permanent formwork and cast-in-place bridge deck slab construction method
The invention discloses a high-toughness ultrathin permanent formwork and a cast-in-place bridge deck slab construction method, and relates to the technical field of bridge construction, and the technical scheme is that the high-toughness ultrathin permanent formwork is formed by prefabricating C80 high-strength concrete; a reinforcing mesh is arranged in the middle of the interior of the permanent formwork, and the distance between reinforcing steel bars is 30 cm. A plurality of shear nail hole channels are symmetrically formed in the two ends of the permanent formwork in a penetrating mode. The construction method has the beneficial effects that the prefabricated permanent formwork is installed in a suspended mode through the concrete beam, the permanent formwork can serve as a construction platform, reinforcing steel bars are bound on the permanent formwork, meanwhile, the permanent formwork can serve as a reinforcing steel bar protection layer of the bridge deck slab, a scaffold does not need to be erected on the ground, the scaffold erecting and dismantling construction procedures can be reduced, and the construction efficiency is improved. The labor intensity of constructors is reduced, the working efficiency is improved, the construction period is shortened, the scaffold leasing cost is reduced, the scaffold erecting and dismantling construction labor cost is reduced, and the safety of the constructors is guaranteed.
本发明公开了一种高韧性超薄永久模板及现浇桥面板施工方法，涉及桥梁施工技术领域，技术方案为，一种高韧性超薄永久模板，永久模板由C80高强混凝土预制而成；所述永久模板内部中间位置设置有钢筋网，钢筋之间的间距为30cm；所述永久模板的两端对称且贯通设置有若干剪力钉孔道。本发明的有益效果为：利用混凝土梁悬空安装预制完成的永久模板，永久模板可作为施工平台并在该永久模板上绑扎钢筋，同时永久模板可用作桥面板的钢筋保护层，不需要从地面搭设脚手架，可减少脚手架搭设及拆除施工工序，降低施工人员劳动强度，提高工作效率，缩短施工工期，降低脚手架租赁费用，降低脚手架搭设及拆除施工人工成本，保证施工作业人员的安全性。
