Description

Technical Field

[0001] The invention belongs to the technical field of building structures, and in particular relates to a method for assembling a spherical bearing. Background Art

[0002] The connection between the traditional building structure steel column and the roof steel structure is usually a rigid connection or bolt hinge, which not only affects the aesthetics of the building structure, but also has a large force and deformation when dealing with dynamic loads such as wind loads and earthquakes. At present, the steel column and the truss are often connected by joint bearings, which greatly improves the seismic performance and architectural aesthetics of the structure itself. Universal joint bearings are also gradually used in the design of civil building structures such as various stadiums.

[0003] The joint bearing connection method has clear force, simple construction and convenient disassembly, which can meet the requirements of green building design and construction at the same time. It is especially suitable for special steel structures with large span, large floor height and heavy load. The joint bearing is a precision-machined component with high requirements for installation accuracy. For example, the ear plate hole for installing the joint bearing must allow the joint bearing to be freely inserted, and ensure that the center lines of the joint bearing hole and the inner hole of the ear plate coincide when the joint bearing is installed, and the clearance between the joint bearing and the hole wall is within the design range. However, the joint bearing parts are all thick plates, and the strain is large during welding, which can easily cause concentricity deviation between the joint bearing hole and the inner hole of the ear plate, making it difficult to install the joint bearing relative to the inner hole of the ear plate, affecting the subsequent installation of the oblique V-column of the joint bearing and the accuracy, life and performance of the joint bearing.
