Sliding joints based on spherical plain bearings

Abstract

The invention discloses a knuckle bearing based slide joint. The knuckle bearing based slide joint comprises an outer lug plate, a knuckle bearing, a hinge pin and a middle lug plate. The outer lug plate comprises two side lugs arranged at an interval, an inner ring of the knuckle bearing fixedly sleeves one end of the hinge pin, and the other end of the hinge pin is fixedly connected with the middle lug plate. Opposite sides of the two side lugs are provided with slide portions protruding inwards respectively, a slide plate is fixed to each slide portion, the outer periphery of an outer ring of the knuckle bearing is provided with two parallel slide planes which are clamped between the two slide plates, and each of the two slide planes is in slide connection with the corresponding slide plate on the same side. The knuckle bearing based slide joint is mounted in a building structure, a mechanism connected with the outer lug plate and a component connected with the middle lug plate are capable of rotating mutually within a certain range and further capable of moving vertically and transversely, wind resistance and seismic resistance are realized, permanent deformation of the building structure is avoided, and safety of the building structure is guaranteed.

Description

Technical field [0001] The present invention relates to a building node, in particular to a sliding node based on an articulated bearing. Background technique [0002] Joint bearing nodes for construction are mainly used to connect the intermediate mechanisms at both ends of the building structure. The common structure is that the pin shaft passes through the inner hole of the joint bearing, the two ends of the pin shaft are supported on the outer ear plate, and the outer ring of the joint bearing is fixed on the middle ear plate. Since the inner and outer rings of the joint bearing can rotate relatively, the middle ear plate and the outer ear plate connected with the inner and outer rings of the joint bearing can rotate relatively. In the existing joint bearing joints for construction, the middle ear plate and the outer ear plate can only rotate with each other, and cannot achieve vertical and lateral sliding. The internal stress of the steel structure cannot be released or som...

AI Technical Summary

Problems solved by technology

In the existing joint bearing joints used in construction, the middle ear plate and the outer ear plate can only rotate with each other, and vertical and lateral sliding cannot be realized. The internal stress of the steel structure cannot be released or some loads cannot be offset, resulting in damage to the steel structure
