Swivel device for solid-web cantilever steel beam in swivel bridge and construction method
The invention discloses a swivel device of solid-web cantilever steel beams in a swivel bridge and a construction method, the swivel device is located at the bottom of a pier, the solid-web cantilever steel beams and supporting legs are adopted to provide lateral support for the swivel bridge, the solid-web cantilever steel beams are arranged every 30 degrees, 45 degrees or 60 degrees, and the solid-web cantilever steel beams are connected with the swivel bridge through steel sleeves. Rib plates are arranged on the inner sides of the steel sleeves, and holes allowing bolts to pass through are formed in the joints of the steel sleeves and cantilever steel beams. The method has the advantages that the cantilever steel beam transversely adopts the inner and outer ring beams to realize an integral effect, and the steel sleeve can also be used as a template; when the bridge rotates, the steel strand is wound around the outer ring beam and the middle of the outer side of the end of the cantilever steel beam to provide power for rotating the bridge. The structure is reasonable in stress and convenient to construct, the concrete pouring volume of the swivel structure is effectively reduced, the stability of the swivel structure is improved, part of the swivel structure can be recycled, the concept of green and sustainable development of buildings is embodied, and innovation and development of bridge swivel engineering are facilitated.
本发明公开了一种转体桥梁中实腹式悬臂钢梁的转体装置及施工方法，转体装置位于桥墩底部，采用实腹式悬臂钢梁、撑脚对转体桥梁提供侧向支撑，悬臂钢梁每30°、45°或60°布置一道，实腹式悬臂钢梁与转体桥梁采用钢套筒连接，钢套管内侧带有肋板，与悬臂钢梁连接处带有可通过螺栓的孔洞。本发明的优点在于：悬臂钢梁横向采用内外圈梁实现整体效应，钢套筒可兼做模板使用；桥梁转体时，钢绞线缠绕于外圈环梁与悬臂钢梁端部的外侧中部，为转体桥梁提供动力；该结构受力合理，施工便捷，有效减少了转体结构混凝土浇筑体积，提高了转体结构的稳定性，还可实现转体结构部分可回收，体现了建筑绿色可持续发展的理念，有利于桥梁转体工程的创新与发展。
