Hemispherical support node and manufacturing process thereof

Abstract

The invention discloses a hemispherical support node. The hemispherical support node comprises a support baseplate, a circular pipe and a hemisphere body, the circular pipe is arranged above the support baseplate, the hemisphere body is arranged above the circular pipe, a stiffening assisting plate is arranged in the hemisphere body, and a group of stiffening plates are arranged in the circular pipe. According to the hemispherical support node, the structure of the support node is optimized, and the hemisphere body is arranged; a force is transmitted through a spherical surface, so that a reaction force acting on supporting concrete is relatively uniform, and the use stability and safety of the support node are greatly improved. The invention also relates to a manufacturing process of thehemispherical support node, and the problems are solved that the operation during manufacturing of large-diameter thick-walled hemispherical support nodes is difficult, the welding quality is unlikelyto be guaranteed, and deformation is easily caused after welding.

Description

technical field [0001] The invention belongs to the technical field of steel structure buildings, in particular to a hemispherical support node and a manufacturing process thereof. Background technique [0002] Building steel structure has many advantages such as superior earthquake resistance, green environmental protection, quick and convenient construction, high space utilization rate, unique and novel design, etc., and has become the development direction of international building structures. Among many classic steel structures, spherical bearings are widely used in long-span airport terminals, stadiums and railway stations. [0003] Most of the existing support nodes are of the bracket type. In the actual use process, there will often be uneven reaction force, resulting in instability problems in the later use process.

Problems solved by technology

[0003] Most of the existing support nodes are of the bracket type. In the actual use process, there will often be uneven reaction force, resulting in instability problems in the later use process. At the same time, the existing support nodes are in the During the manufacturing process, most of the construction methods adopt traditional welding methods. However, the welding temperature and welding method also have a serious impact on the quality of the support joints. Therefore, the existing support joints and their manufacturing methods have yet to be developed. Improve
