Universal spherical hinge rubber support applied to assembly type bent slope inclined road beam bridge
The universal spherical hinge rubber support comprises a lower support body and an upper support body, the lower support body comprises a rubber base body, a plurality of steel plates evenly embedded in the lower portion of the rubber base body and a concave steel spherical hinge seat arranged on the upper portion of the rubber base body, and the concave steel spherical hinge seat is arranged on the upper portion of the rubber base body. A concave spherical surface is arranged in the middle of the top surface of the concave steel ball hinge seat; the upper support is a convex steel ball hinged support, and the bottom face of the upper support is provided with a convex spherical face matched with the concave spherical face. The universal spherical hinge rubber support applied to the assembly type bent slope inclined road beam bridge adapts to inclination angle errors during beam body installation and inclination angle changes caused by beam body deformation in the operation process, it is guaranteed that the lower portion of the rubber support is evenly stressed, the service life of the support is prolonged, the replacement frequency of the support is reduced, secondary diseases of an upper structure are reduced, and the service life of the support is prolonged. And the disease treatment frequency and cost are reduced.
本发明涉及一种应用于装配式弯坡斜公路梁桥的万向球铰橡胶支座，其包括下支座和上支座，所述下支座包括橡胶基体、均匀嵌入在橡胶基体下部的多个钢板以及设置在橡胶基体上部的凹形钢球铰座，所述凹形钢球铰座顶面中部设有凹球面；所述上支座为凸形钢球铰座，其底面设有与所述凹球面相适配的凸球面。本发明提供的一种应用于装配式弯坡斜公路梁桥的万向球铰橡胶支座，自适应梁体安装时的倾角误差和运行过程中梁体形变而发生的倾角变化，保证橡胶支座下部受力均匀，提高支座使用寿命，降低支座更换频率，减少上部结构次生病害，降低病害整治的频次和费用。
