Bridge deck structure at inverted T-shaped bent cap of simply supported steel-concrete composite beam bridge and construction method
The invention relates to a simply supported steel-concrete composite beam bridge deck structure at an inverted T-shaped cover beam, which comprises a simply supported steel main beam, a concrete bridge deck, a welding stud connecting piece, a perforated connecting steel plate, a support, an inverted T-shaped cover beam and a bridge pier, and is characterized in that the inverted T-shaped cover beam consists of an upper inverted T-shaped cover beam web and a lower inverted T-shaped cover beam flange; each simply-supported steel main beam comprises an upper flange plate, a web and a lower flange plate, a plurality of welding stud connecting pieces installed on the perforated connecting steel plates are arranged on the upper surface of the upper flange plate of each simply-supported steel main beam at certain intervals, and an inverted-T-shaped bent cap web is arranged between the beam ends of every two adjacent simply-supported steel main beams. The concrete bridge deck crosses the upper portion of the inverted-T-shaped bent cap web and continuously extends between the upper portions of the two adjacent simply-supported steel girders, and the perforated connecting steel plate is installed between the upper surfaces of upper flange plates of the two adjacent simply-supported steel girders and embedded in the concrete bridge deck. The structure is simple.
本发明涉及一种简支钢‑混组合梁桥倒T形盖梁处桥面结构，包括简支钢主梁、混凝土桥面板、焊钉连接件、开孔连接钢板、支座、倒T形盖梁、桥墩，所述倒T形盖梁由上部倒T形盖梁腹板和下部倒T形盖梁翼缘组成，所述简支钢主梁均包括上翼缘板、腹板和下翼缘板，所述简支钢主梁的上翼缘板上表面均按一定间距布置若干安装在开孔连接钢板上的焊钉连接件，相邻两跨简支钢主梁的梁端之间为倒T形盖梁腹板，该梁端与倒T形盖梁腹板之间均留有伸缩间隙，所述混凝土桥面板跨越倒T形盖梁腹板上部并在相邻两跨简支钢主梁的上部之间连续延伸，所述开孔连接钢板安装在相邻两跨简支钢主梁的上翼缘板上表面之间并预埋在混凝土桥面板内部，结构简单。
