Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel structure support frame which is easy to assemble. Background Art

[0002] In building structures, support frames are very common. Some facilities must be supported first to avoid collapse before they are firmly established. Steel structure support frames are widely used due to their light weight, high strength, good overall rigidity and strong deformation ability.

[0003] The patent with publication number CN218715431U discloses a steel structure support frame, which relates to the field of steel structure design technology and solves the technical problems of fixed connection and complicated disassembly process of the support frame. The patent comprises a column, a first beam and a second beam. When the column is connected with the first beam, the block on the connecting column is inserted into the arc groove along the guide groove in the connecting piece, and then the first beam is rotated to dislocate the block from the guide groove so that the block is clamped in the arc groove to improve the stability of the connection. At the same time, the sleeve threadably connects the connecting piece with the first beam to make the connection part tighter. When disassembling, the sleeve is first screwed to one end to expose the connecting part of the connecting piece and the first crossbar, and then the first crossbar is rotated to drive the connecting column to rotate at the same time. When the block on the connecting column just rotates to one end of the guide groove, the reaction force of the spring pushes the connecting column to move outward, so that the connecting column is separated from the connecting piece, and the disassembly is more convenient.

[0004] During use of the above-mentioned steel structure support frame, two adjacent columns are threadedly connected to the columns through the first crossbeam, the second crossbeam, the sleeve and the connector. This connection method is complicated to operate, inconvenient to use and relatively poor in practicality. Utility Model Content
