Orthotropic UHPC combined bridge deck slab adopting steel ribs and construction method
The invention relates to an orthotropic UHPC combined bridge deck slab adopting steel ribs, which comprises a UHPC bridge deck slab and the orthotropic steel ribs, the UHPC bridge deck slab is paved above the orthotropic steel ribs, and the orthotropic steel ribs comprise inverted T-shaped steel beams which are transversely arranged and closed ribs which are longitudinally arranged; the inverted-T-shaped steel beams and the closed ribs are distributed in the transverse direction and the longitudinal direction of the UHPC bridge deck slab respectively, the closed ribs are connected with the UHPC bridge deck slab through PBL perforated plate connecting pieces, the inverted-T-shaped steel beams are connected with the UHPC bridge deck slab through PBL perforated plate connecting pieces, longitudinal steel bars penetrate through the perforated positions of the inverted-T-shaped steel beams, transverse steel bars penetrate through the perforated positions of the closed ribs, and the transverse steel bars penetrate through the perforated positions of the UHPC bridge deck slab. The steel bars in the transverse direction and the longitudinal direction form a reinforcing mesh between orthotropic steel ribs, and the orthotropic steel ribs and the reinforcing mesh are arranged on the bottom layer of the UHPC bridge deck slab. The invention further provides a construction method of the combined bridge deck slab. The invention has the advantages of reliable structure and easiness in construction.
本发明涉及一种采用钢肋的正交异性UHPC组合桥面板，包括UHPC桥面板、正交异性钢肋，所述的UHPC桥面板铺装在正交异性钢肋上方，正交异性钢肋包括横向布置的倒T形钢梁以及纵向布置的闭口肋，所述的倒T形钢梁与闭口肋分别分布在UHPC桥面板的横向和纵向方向，闭口肋采用PBL开孔板连接件与UHPC桥面板连接，倒T形钢梁采用PBL开孔板连接件与UHPC桥面板连接，在倒T形钢梁开孔处贯穿有纵向钢筋，在闭口肋开孔处贯穿有横向钢筋，横纵两方向钢筋形成正交异性钢肋间钢筋网，正交异性钢肋及其钢筋网布置于UHPC桥面板的底层。本发明同时给出此种组合桥面板的施工方法。本发明具有结构可靠易于施工的优点。
