High-thrust hinged steel arch foot for steel arch bridge
The invention discloses a high-thrust hinged steel arch foot for a steel arch bridge. The high-thrust hinged steel arch foot is characterized by comprising a concave base, a sliding plate cushion block for reducing the friction coefficient and a convex rotating block connected with a steel main arch, the concave base is fixed to the reinforced concrete skewback through anchor bolts, a groove is formed in the concave base, the sliding plate cushion block is consistent with the groove in shape and attached to the bottom of the groove, one end of the convex rotating block is arranged in the groove of the concave base, and the other end of the convex rotating block is connected with the steel main arch. The concave base, the sliding plate cushion block and the convex rotating block serve as arch feet, and the bearing capacity of the device is improved; in addition, a polytetrafluoroethylene sliding plate cushion block is arranged, the friction coefficient of a rotation interface is reduced, free rotation of the arch springing is achieved, main arch redundant force is reduced, and structural performance is improved.
本发明公开了一种用于钢拱桥的大推力铰接钢拱脚，其特征在于：包括凹形基座、用于降低摩擦系数的滑板垫块、以及与钢主拱相连的凸形转动块；所述凹形基座通过锚栓固定在钢筋混凝土拱座，凹形基座上设有凹槽，滑板垫块的形状与凹槽一致且贴合在凹槽底部，所述凸形转动块一端置于凹形基座的凹槽内，另一端与钢主拱相连。本发明将凹形基座、滑板垫块以及凸形转动块作为拱脚，提高了装置的承载能力；另外，设置聚四氟乙烯滑板垫块，降低转动界面摩擦系数实现拱脚自由转动，从而降低主拱赘余力，改善结构性能。
