Wide prefabricated bridge deck slab and construction method thereof
The invention discloses a wide prefabricated bridge deck slab, and relates to the field of civil engineering. According to the technical scheme, the prefabricated bridge deck slab is characterized bycomprising a metal net and a concrete layer wrapping the metal net; the metal net is pulled out to form the pre-camber; the concrete layer forms the same pre-camber along with the pre-camber of the metal net, and the prefabricated bridge deck slab is formed. Longitudinal and/or transverse rib plates are arranged above the prefabricated bridge deck slab. A plurality of through holes are formed in the rib plates, and the opening directions of the through holes are perpendicular to the length directions of the rib plates; reinforcing steel bars penetrate through the through holes and are fixedlyconnected with the through holes. According to the invention, the reinforcing steel bars penetrate through the through holes in the rib plates, so that when concrete is poured in subsequent field construction, the binding power between the concrete cured after prefabrication and the concrete newly poured in situ is increased, and the cracking phenomenon is reduced. Meanwhile, the invention furtherdiscloses a construction method of the wide prefabricated bridge deck slab.
本发明公开了一种宽幅预制桥面板，涉及土木工程领域。其技术方案要点如下：包括金属网和包覆于金属网的混凝土层，将金属网拉伸出预拱度，混凝土层也随金属网的预拱度而形成同样的预拱度，形成预制桥面板；在预制桥面板上方，设置有纵向和/或横向肋板；肋板上设置有若干个贯穿孔，贯穿孔的开孔方向垂直于肋板的长度方向；贯穿孔供钢筋贯穿而过，钢筋与贯穿孔固定连接。本发明中利用钢筋穿过肋板上的贯穿孔，在后续的现场施工浇筑混凝土时，使预制后养护过的混凝土与现场新浇筑的混凝土之间的粘结力增大，减少开裂现象的发生。同时，本发明中还请求保护一种宽幅预制桥面板的施工方法。
