Steel structure universal spherical hinge support

Abstract

The invention discloses a steel structure universal spherical hinge support, and relates to the technical field of building steel structures. The steel structure universal spherical hinge support comprises an annular base, wherein a circular groove is formed in the top of the annular base; a cylindrical sliding bottom plate is movably arranged in the circular groove; the diameter of the cylindrical sliding bottom plate is greater than that of the inner ring of the annular base; the top of the cylindrical sliding bottom plate is a concave spherical surface, and a cylindrical sliding upper plate is arranged on the cylindrical sliding bottom plate in a sliding manner; the bottom of the cylindrical sliding upper plate is a convex spherical surface matched with the concave spherical surface; and the top of the annular base is connected with a circular top plate through bolts. Universal rotation can be achieved, and the problem of single-direction rotation steel structure connection is solved. By adopting the integral assembly design, standardized production can be realized, the cost is reduced, the on-site mounting time is saved, and the working efficiency is improved. An oil injection lubricating system is designed to ensure the lubricity and safety of the whole structure.

Description

technical field [0001] The invention relates to the technical field of building steel structures, in particular to a steel structure universal spherical hinge support. Background technique [0002] At present, the common method for the support of the building curtain wall is to connect the ear plate through the bolt, and the characteristic is that it can only rotate around the direction of the bolt axis. There is no problem in using this method on the curtain wall of ordinary plane buildings. However, with the development of economy and society, the design of architectural shapes, including building skins and building curtain walls, is becoming more and more complex, and the application of three-dimensional special-shaped curtain walls is becoming more and more extensive. Due to the shape of the three-dimensional special-shaped curtain wall, the curtain wall is affected by wind loads in various directions, requiring the curtain wall support not only to have the function of ...

AI Technical Summary

Problems solved by technology

Due to the shape of the three-dimensional special-shaped curtain wall, the curtain wall is affected by wind loads in various directions, requiring the curtain wall support not only to have the function of force transmission but also to have the ability to rotate in multiple directions, otherwise a large fixed-end bending moment will be formed at the curtain wall support , resulting in a large concentrated stress, resulting in the destruction of the curtain wall support

Therefore, the structure of the traditional curtain wall support is not suitable for the three-dimensional special-shaped curtain wall with multi-directional deformation requirements.
