The invention discloses a prefabricated bridge deck slab of a cable-stayed bridge and a construction method, and relates to the technical field of bridge engineering. The prefabricated bridge deck of the cable-stayed bridge comprises a square bridge deck main body and hanging lugs arranged on the bridge deck main body, and further comprises two supporting beams integrally poured below the bridge deck main body, and grouting holes are formed in the upper face of the bridge deck main body and the lower ends of the supporting beams in a penetrating mode. The two supporting beams correspond to grooves in two steel beams of the cable-stayed bridge, the supporting beams of the prefabricated bridge deck can be carried on the auxiliary moving devices embedded in the upper grooves so that the prefabricated bridge deck can slide in the length direction of the steel beams, and after the auxiliary moving devices are withdrawn, the supporting beams can be embedded in the grooves in the steel beams of the cable-stayed bridge. The laying construction efficiency and the connection strength of the prefabricated bridge deck slab are effectively improved.
本发明公开了一种斜拉桥预制桥面板及施工方法，其涉及桥梁工程技术领域。本发明的斜拉桥预制桥面板包括方形桥面板主体和设置在桥面板主体上面的挂耳，还包括在所述桥面板主体下面一体浇筑的两条支撑梁，所述桥面板主体上面与所述支撑梁的下端贯通有灌浆孔，并且两条支撑梁与斜拉桥的两条钢梁上凹槽对应，预制桥面板的支撑梁能搭载在嵌入上凹槽内的辅助移动装置上，使预制桥面板能沿钢梁长度方向滑行，当撤出所述辅助移动装置后，支撑梁能嵌入斜拉桥的钢梁上凹槽内。本发明有效提高预制桥面板铺设施工效率和连接强度。
