Swivel device of truss type cantilever steel beam in swivel bridge and construction method
The invention discloses a swivel device for truss type cantilever steel beams in a swivel bridge and a construction method, and the swivel device is composed of a plurality of truss type cantilever beams, a plurality of inner transverse connecting beams, a plurality of outer transverse connecting beams, an upper spherical hinge, a lower spherical hinge, supporting feet, a slide way, a sand cylinder, a traction cable, two counter-force seats and two jacks. The truss-type cantilever beams are symmetrically arranged around the centroid of the cross section of the pier at equal angles, one ends of the truss-type cantilever beams are fixed to the lower portion of the pier, the other ends of the truss-type cantilever beams are connected with the supporting feet, the supporting feet fall on the slideways, the slideways are annular and arranged in the center of the top of a lower bearing platform, and the traction cable is anchored to the pier, wound around the outer sides of the truss-type cantilever beams and penetrates through the counter-force support and the jack. The upper spherical hinge is embedded into the bottom of the pier, and the lower spherical hinge is located in the center of the slideway. The swivel device and the construction method thereof have the advantages that an upper bearing platform of a swivel structure is eliminated, the swivel device can be recycled, hinge sealing operation is facilitated, and the construction cost is reduced.
本发明公开了一种转体桥梁中桁架式悬臂钢梁的转体装置及施工方法，转体装置由若干桁架式悬臂梁、若干内横向连梁、若干外横向连梁、上球铰、下球铰、撑脚、滑道、砂筒、牵引索、两个反力座和两个千斤顶组成，桁架式悬臂梁绕桥墩截面形心等角度对称布置，所述桁架式悬臂梁一端固定于桥墩下部，另一端连接撑脚，撑脚落于滑道，滑道呈环形，设置在下承台顶部中心，牵引索锚固于桥墩，缠绕于桁架式悬臂梁外侧，穿过反力支座与千斤顶，上球铰嵌入桥墩底部，下球铰位于所述滑道中心。该转体装置及其施工方法具有消除转体结构上承台、实现转体装置可循环利用、方便封铰作业和降低工程造价的优点。
