Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a steel structure node for prefabricated buildings. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to a factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the building construction site, and then assembled and installed on-site through reliable connection methods.

[0003] In the prior art, steel beams and columns are widely used in frame buildings. Nodes where steel beams and steel columns are vertically connected usually use node connectors for pre-positioning and then welding reinforcement to ensure the firm connection of steel beams and steel columns.

[0004] However, when installing the connectors at the nodes of traditional steel beams and steel columns, multiple groups of bolt structures need to be used for installation, which results in a large workload and is not conducive to improving the on-site construction efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a steel structure node for prefabricated buildings to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A steel structure node for prefabricated buildings includes a connecting buckle plate installed at the assembly of a steel column and a steel beam. There are two groups of connecting buckle plates, which are symmetrically distributed about the steel column.
