Description

Technical Field

[0001] The utility model relates to the technical field of steel components, in particular to a box-shaped steel component. Background Art

[0002] A Chinese patent application with application number 201710428971.X discloses a large-section, thick-walled welded box-type structure. Specifically, the structure comprises a box-type structure, the side walls of which are provided with a corbel assembly, which is positioned within the box-type structure by a reinforcement assembly. The corbel assembly includes a horizontal corbel fixed to the box-type structure, with an inclined corbel provided between the upper portion of the horizontal corbel and the box-type structure, and between the lower portion of the horizontal corbel and the box-type structure. The reinforcement assembly includes a transverse diaphragm and a longitudinal stiffening plate, the transverse diaphragm being fixed to the box-type structure in a spaced-apart manner, and the longitudinal stiffening plate being arranged perpendicularly to the transverse diaphragms. This large-section, thick-walled welded box-type structure has the following shortcomings: Firstly, the transverse diaphragm is a dense, solid plate structure that divides the interior of the box-type structure into left and right sections. After concrete is poured later, the concrete in the left and right sections of the box-type structure cannot penetrate each other, making it difficult to connect the two sections, which is detrimental to overall strength and density. Secondly, the reinforcement assembly is not arranged properly, resulting in poor overall strength. Utility Model Content
