UHPC prefabricated bridge deck unit without temporary support, bridge deck and construction method thereof
The invention provides a temporary-support-free UHPC prefabricated bridge deck unit which comprises a plurality of UHPC prefabricated parts adjacently arranged in the transverse bridge direction, the adjacent UHPC prefabricated parts are connected into a whole through a plurality of sets of steel bar trusses, the steel bar trusses are arranged in the transverse bridge direction, the lower portions of the steel bar trusses are embedded in the UHPC prefabricated parts, and the upper portions of the steel bar trusses are embedded in the UHPC prefabricated parts. The upper portion of the steel bar truss is arranged on the surface of the UHPC prefabricated part in a protruding mode. The invention further provides a bridge deck slab and a construction method thereof. The UHPC prefabricated part can serve as a bottom die during pouring of a concrete cast-in-place layer, the UHPC prefabricated bridge deck slab unit formed by the UHPC prefabricated part and the steel bar truss can bear temporary construction loads, a pouring formwork and a supporting formwork do not need to be adopted during construction of the cast-in-place concrete layer, and temporary supporting does not need to be adopted.
本发明提供一种无临时支撑的UHPC预制桥面板单元，包括沿横桥向相邻设置的多块UHPC预制件，相邻所述UHPC预制件通过多组钢筋桁架连接为一整体，所述钢筋桁架沿横桥向布置，所述钢筋桁架的下部埋设于所述UHPC预制件中，所述钢筋桁架的上部凸出设于所述UHPC预制件表面上。本发明还提供一种桥面板及其施工方法。本发明的UHPC预制件不仅可作为混凝土现浇层浇筑时的底模，而且其与钢筋桁架形成的UHPC预制桥面板单元能够承受施工临时荷载，在现浇混凝土层施工时无需采用浇筑模板及支撑模板，无需采用临时支撑。
