Two-way sliding rotary hinge bearing

Abstract

The invention belongs to the technical field of building and bridge space structure seismic prevention, and relates to a bidirectional slide rotary hinged support which comprises an upper connecting plate and a lower connecting plate in parallel. An X-direction slide plate is arranged on the bottom face of the upper connecting plate in a sliding mode. A Y-direction slide plate is arranged on the top face of the lower connecting plate in a sliding mode. A rotary shaft is arranged in a middle hole of the X-direction slide plate in a matched mode. The rotary shaft is connected with the Y-direction slide plate through a limiting bolt. A slide plate is arranged between the upper end face of the rotary shaft and the upper connecting plate. The hinged support can slide in two directions, space slide limitation is eliminated, and meanwhile twisting and drawing can be resisted.

Description

technical field [0001] The invention belongs to the anti-seismic technical field of buildings and bridge space structures, and relates to a two-way sliding rotary hinge support. Background technique [0002] my country is one of the countries with the strongest seismic activity and the worst earthquake disasters in the world. The promenades and long-span bridges in the building are used as connecting passages between buildings, which are widely used in modern architectural design. Through such connection design methods, it is more convenient for people to come and go in the building. However, due to the generally large spans of promenades and overpasses, in case of [0003] During disasters such as earthquakes and storms, the two ends of the corridor or overpass often twist, pull, sink up and down, and overturn, which leads to damage to the corridor and overpass, and cannot guarantee the safety and normal use of the corridor during the earthquake. At present, the existing ...

[0003] During disasters such as earthquakes and storms, the promenades or overpasses often twist, pull, sink up and down, and overturn at both ends, resulting in damage to the promenades and overpasses, and the safety and normal use of the promenades in earthquakes cannot be guaranteed.

At present, the existing sliding bearings are still insufficient in the stability of the building during use. Specifically, the anti-stability is poor, the pull-out resistance is weak, the limitation of one-way sliding is large, and the torsion resistance is poor.
