Description

Technical Field

[0001] The utility model belongs to the technical field of steel beam structures and relates to a square steel beam structure. Background Art

[0002] A square beam is a beam with a square cross-section. Usually, most beams in construction projects are square beams. During construction, the connection between beams is generally achieved by first welding plugs at both ends of the square beam, and then fixing the beams with plugs between the plugs. However, this method has the following problems. Since the existing plugs are fixed to the end faces of the square beams by welding, and the square beams are hollow inside, the welding area between their end faces and the plugs is small, which will greatly affect the welding effect, resulting in a welding position offset, resulting in the position between the plug and the end face of the square beam not completely corresponding. The pin is connected by sequentially penetrating the through holes on the two plugs. The offset of the plug welding position will also cause the position between the two through holes to not completely correspond, making it difficult to work with the pin, greatly affecting the construction efficiency.

[0003] Therefore, a square steel beam structure is designed to overcome the above problems. Utility Model Content
