Distribution mode of nonmetal sliding plate of friction pair of bridge bearing

Abstract

Disclosed is a distribution mode of a nonmetal sliding plate of a friction pair of a bridge bearing. The nonmetal sliding plate consists of a central sliding plate and split sliding plates which are separately embedded in corresponding grooves formed in a base plate; the central sliding plate is an integral sliding plate; the center of the central sliding plate is arranged in correspondence with the center of the friction pair of the bridge bearing; the split sliding plates are a plurality of sliding plates of which the size is smaller than the size of the integral sliding plate; and the splitsliding plates are evenly distributed on the outer side of the central sliding plate in the distribution mode of at least one layer of concentric circle. The distribution mode of the nonmetal slidingplate of the friction pair of the bridge bearing has the beneficial effects of realizing the high bearing capacity of the friction pair of the bearing, effectively improving the bearing capacity andconstraining ability of the nonmetal sliding plate of the friction pair of the bearing, effectively reducing the risk of detachment of the nonmetal sliding plate of the friction pair of the bearing, effectively reducing the structural size of the bearing, and further reducing the manufacturing cost of the bearing.

Description

technical field [0001] The invention relates to the technical field of friction pairs, in particular to a distribution method of non-metallic sliding plates for friction pairs of bridge supports. Background technique [0002] As a key component connecting the superstructure and substructure of the bridge span, the bridge support can adapt to the displacement and rotation of the superstructure, and transmit the dead load and live load reaction force of the superstructure of the span to the piers of the substructure. The bearing, displacement and rotation functions of the bridge bearing are completed through the plane friction pair and the spherical friction pair. The plane friction pair and spherical friction pair of the support are usually composed of metal friction surface and non-metallic sliding plate. The distribution and restraint mode of the non-metallic sliding plate are closely related to the bearing capacity, sliding capacity, rotation capacity and other special fun...

AI Technical Summary

Problems solved by technology

The fragmented mosaic method has a strong constraint ability on the slide, which can greatly increase the bearing capacity of the slide and improve the reliability of various functions of the support. However, the utilization rate of the bearing area is low, and the bearing area required under the same design load is relatively small large, which in turn leads to an increase in the external dimensions of the support and an increase in manufacturing costs; the utilization rate of the pressure-bearing area of ​​the whole plate fixing method is high, and the required pressure-bearing area is small under the same design load, and the external dimensions of the support are small. Manufacturing The cost is reduced, but the binding ability to the skateboard is relatively weak, which increases the risk of the skateboard falling out
