Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure connection, in particular to a connection node for round tube supports of steel structure buildings. Background Art

[0002] Steel structure buildings are increasingly widely used in various fields. Compared with concrete structures, steel plates or steel sections are used instead of reinforced concrete, which have higher strength and better earthquake resistance. The components can be processed in factories and installed on site, which greatly shortens the construction period and reduces on-site labor. It is more energy-saving and green. Due to the different process requirements of various industries, more and more industrial plants or buildings use round tube supports for support.

[0003] At present, there are generally three ways to connect the existing round tube supports and steel columns: direct welding of the round tube supports and steel columns (or round tube supports), bolt connection of the round tube supports and steel columns (or round tube supports) through corbels and butt connection plates, and on-site welding connection of the round tube supports and steel columns through plug plates.

[0004] The above connection method has the following disadvantages:

[0005] In the welding method of directly intersecting the round tube support and the steel column (or round tube support), there is an intersecting mouth between the round tube support and the steel column (or round tube support), and the round tube is round. During on-site installation, it is difficult to match the intersecting mouths, which is inconvenient for installation;

[0006] In the method of connecting the round tube support and the steel column (or round tube support) through the corbel and the butt connection plate bolt connection, the corbel with a through hole and the connecting ear plate at the connection of the round tube support are positioned, which is difficult to match in the factory. After the on-site installation, for the sake of visual beauty, the connection positioning ear plate needs to be cut off and polished clean. At the same time, the welds at the corbel of the round tube support at the intersection of the round tube support need to be supplemented, which is inconvenient to install and wastes resources to a certain extent.

[0007] In the method of connecting the round tube support and the steel column by on-site welding through the plug plate, there are cross-shaped sockets at both ends of the round tube support that need to be welded to the cross-shaped plug plates on the corbel, which is difficult to install and the accuracy is not easy to guarantee.

[0008] To solve the above problems, we propose a connection node for circular tube supports of steel structure buildings. Utility Model Content
