One-way sliding knuckle bearing joint

Abstract

The invention discloses a one-way sliding knuckle bearing joint. The one-way sliding knuckle bearing joint comprises an external lug plate, a knuckle bearing, a hinge pin and a middle lug plate. The outer lug plate comprises two side lugs which are arranged in a spaced mode, the two ends of the hinge pin are fixed to the two side lugs respectively, an inner ring of the knuckle bearing is fixedly arranged on the hinge pin in a sleeving mode, and an outer ring of the knuckle bearing is sleeved with a bearing pedestal. A guiding through hole is formed in the lower portion of the middle lug plate, first sliding plates are arranged on the two opposite side faces of the guiding through hole respectively, and the bearing pedestal is connected between the two first sliding plates in a sliding mode and slides in the vertical direction. Pressing covers are fixed to two shaft end faces of the guiding through hole of the middle lug plate respectively. The opposite side faces of the two pressing covers are provided with second sliding plates in sliding cooperation with the shaft end faces of the bearing pedestal respectively. By means of the structure, a mechanism connected with the middle lug plate and a mechanism connected with the middle lug plate can rotate mutually within a certain range and can also slide in the vertical direction, the internal stress in a building structure can be effectively released or a number of loads can be offset, and the safety of the building structure is ensured.

Description

technical field [0001] The invention relates to a building node, in particular to a one-way sliding joint bearing node. Background technique [0002] Joint bearing joints 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 used in construction, the middle ear plate and the outer ear plate can only rotate with each other and cannot slip, and the internal stress of the steel structure cannot be released or some loads cannot be offset, resulting i...
