Abstract

The invention discloses a one-way sliding type spherical steel supporting seat. The one-way sliding type spherical steel supporting seat comprises a supporting seat top plate, a supporting seat bottomplate, a spherical crown liner plate, a first plane polytetrafluoroethylene sliding plate, a spherical surface polytetrafluoroethylene sliding plate, a second plane polytetrafluoroethylene sliding plate, a first stainless steel plate, a second stainless steel plate, an upper sliding plate and a middle seat body, the middle seat body is arranged at the upper end of the supporting seat bottom plate, a spherical crown groove which can be matched with the spherical crown lining plate is formed in the upper end of the middle seat body, a lower spherical crown surface of the spherical crown liningplate is arranged in the spherical crown groove, the spherical surface polytetrafluoroethylene sliding plate is arranged between the spherical crown lining plate and the spherical crown groove, and afirst plane polytetrafluoroethylene sliding plate mounting clamping groove which can be matched with the first plane polytetrafluoroethylene sliding plate is formed in the upper end of the spherical crown lining plate. According to the one-way sliding type spherical steel supporting seat, the upper sliding plate is arranged at the upper end of the spherical steel supporting seat, the upper slidingplate can achieve one-way sliding displacement, so that the bridge displacement requirement is met, the safety is improved, the spherical crown lining plate can meet the rotating requirement, the twofunctions of one-way displacement and rotation are met by the spherical steel supporting seat, so that the safety is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of bridge bearings, in particular to the technical field of spherical steel bearings. [0003] 【Background technique】 [0004] The bridge support is an important structural component connecting the upper structure and the lower structure of the bridge. It is a device erected on the pier and supports the upper structure of the bridge on the top surface. Its function is to fix the superstructure to the abutment, withstand various forces acting on the superstructure, and transmit it reliably to the abutment; under the action of load, temperature, concrete shrinkage and creep, the support can adapt to the superstructure The rotation angle and displacement of the upper structure can be freely deformed without additional additional internal force. The spherical bearing refers to a new type of bridge bearing developed on the basis of the basin rubber bearing. Its rotation performance in all directions is co...
