Universal spherical joint supporter with anti-loosening position-limiting structure

Abstract

A universal spherical joint supporter with an anti-loosening position-limiting structure comprises a main spherical joint structural part consisting of a main top base with a concave spherical surface and a main bottom base with a convex spherical surface; the main bottom base consists of a base body, at least three reinforced plates and a steel ball; the steel ball is a convex ball component arranged in the bottom base; the reinforced plates are distributed in the bottom base radially and vertically by taking the vertical middle axis line of the steel ball as a central line; each reinforced plate is provided with a vertical edge closely to the middle axial line of the steel ball; a spherical concave position used for bearing the steel ball is arranged on an upper plate of the reinforced plate closely to the middle axis line by taking the spherical center of the steel ball as a center, and a convex claw is arranged in a space between every two adjacent reinforced plates on the main bottom base correspondingly to the lower circumference of the main top base, thus forming the position-limiting structure of the spherical joint. The position-limiting structure can play roles of preventing loosening, restricting the rotation of the top base around the axis line and bearing the pulling force and has excellent bearing performance; and when the position-limiting structure bears the pulling force, the spherical joint part can rotate slightly and simultaneously.

Description

technical field [0001] The invention relates to a support for buildings, in particular to a universal spherical joint support with an anti-loosening limit structure, which is suitable for building structure systems with large cantilever structures, and is used for the connection between grid frames and column piers. connect. Background technique [0002] In the building structure, the network frame with large cantilever or long-span structure and multiple supporting supports with overhangs needs the supporting supports of the network frame to be able to withstand the deformation of the temperature load, wind load or earthquake load. Slight rotation in two directions does not produce linear displacement and bending moment, and generally adopts the connection node form of spherical hinge pressure bearing, such as figure 1 The commonly used spherical hinge pressure bearing shown is composed of a base, a top seat, a spherical hinge structure, bolts and a connection structure on...

AI Technical Summary

Problems solved by technology

[0004] 1. The tensile and shear resistance of the support is not strong. Under the action of strong tensile and shear forces, the spherical hinge structure is easy to loosen, that is, the convex solid hemisphere is easy to break away from the socket-type semi-concave sphere, so Its load-carrying performance is not high and its reliability is poor;

[0005] 2. The support cannot slide, and the temperature stress cannot be released, so the building components are easily damaged, thereby shortening the service life of the support;

[0006] 3. The support only has a single spherical joint structure, so the design factors considered in the entire building system are relatively scattered, resulting in a weak integrated overall design, which is not conducive to the overall design and construction of the building structure

[0007] 4. Some support nodes have a concave surface, which is prone to problems such as dust accumulation and water accumulation, which will affect the rotation performance of the support and shorten the service life of the support
