Bridge restraining device capable of rotating in plane and method
The invention belongs to the technical field of bridge engineering, and provides a bridge restraining device capable of rotating in a plane and method. The support restraining device is composed of alower support plate, a pressure-bearing rubber plate, an arc-shaped middle steel lining plate, a sealing ring, a polytetrafluoroethylene sliding plate, a stainless steel sliding plate, an upper support plate and bolts. The lower support plate is connected with the pier cap through a bolt, the pressure-bearing rubber plate is arranged in the sealed lower support plate and is in a three-dimensionalstress state, the arc-shaped middle steel lining plate is arranged between the polytetrafluoroethylene sliding plate and the pressure-bearing rubber plate, the stainless steel sliding plate is arranged on the polytetrafluoroethylene sliding plate, and the upper support plate is connected with the main beam through a bolt. The device has the advantages that the basin-type rubber support or the spherical steel support capable of rotating on the plane can adapt to plane rotation of an upper structure of a bridge and temperature deformation, the main beam does not generate temperature secondary internal force, and the basin-type rubber support or the spherical steel support is suitable for a plane curve narrow bridge.
本发明属于桥梁工程技术领域，提供了一种可以平面转动的桥梁约束装置及方法。该支座约束装置，由下支座板、承压橡胶板、弧形中间钢衬板、密封圈、聚四氟乙烯滑板、不锈钢滑板、上支座板和螺栓组成。下支座板通过螺栓与墩帽相连接，承压橡胶板置于密封的下支座板里，处于三向应力状态，弧形中间钢衬板介于聚四氟乙烯滑板和承压橡胶板之间，不锈钢滑板置于聚四氟乙烯滑板上，上支座板通过螺栓与主梁相连接。本发明的效果和益处在于：可平面转动的盆式橡胶支座或球型钢支座能适应桥梁上部结构平面转动，能适应温度变形，主梁不会产生温度次内力，适用于平面曲线窄桥。
