Problems solved by technology

Plate bearings are prone to bearing deflection during use, high maintenance frequency, and short service life
The structure of the spherical bearing includes an upper bearing plate, a spherical crown lining plate, a spherical concave lining plate and a lower bearing plate. The sliding and rotating parts of the spherical bearing are not well sealed, and the cost is high, and installation and maintenance are inconvenient.

Abstract

The invention belongs to the technical field of bridge supports, and discloses a steel stranded rubber support and a production method thereof. The steel stranded rubber support is mainly technically characterized by comprising a convex spherical crown steel stranded support with a convex spherical surface and a concave spherical crown steel stranded support with a concave spherical surface, wherein the convex spherical crown steel stranded support and the concave spherical crown steel stranded support are coated or partly coated by an elastomer. The steel stranded rubber support provided by the invention is large in corner so as to be capable of self-adapting to a corner of a girder body and to effectively prevent biasing of plate type rubber supports. And the convex spherical crown steel stranded support and the concave spherical crown steel stranded support are coated or partly coated by the elastomer, therefore, the stress is not further applied to the peripheral rubber of the support and other elastomer protection layers, and good sealing performance and long service life are achieved. The steel stranded rubber support has the advantages of plate type supports and global supports, also has the advantages of convenience for installation and low cost, and is free of maintenance.

Description

technical field [0001] The invention belongs to the technical field of bridge supports, in particular to a steel hinge rubber support and a preparation method thereof. Background technique [0002] The bearings used in bridge engineering construction include plate bearings, spherical bearings, pot bearings, etc. The structure of the plate bearings includes rubber cushions with stiffened steel plates, and multiple layers of rubber cushions are stacked as needed during installation. . Plate bearings are prone to bearing deflection during use, high maintenance frequency, and short service life. The structure of the spherical support includes an upper support plate, a spherical crown liner, a spherical concave liner and a lower support plate. The sliding and rotating parts of the spherical support have poor sealing performance, high cost, and inconvenient installation and maintenance. Contents of the invention [0003] The first technical problem to be solved by the present ...
