Description

Technical Field

[0001] The utility model relates to the technical field of buildings, and in particular to a cross and box column conversion structure and a conversion connecting component. Background Art

[0002] Prefabricated buildings are buildings that are assembled at the construction site using prefabricated components. Prefabricated buildings are widely used due to their advantages of fast assembly speed, little environmental impact, and labor saving.

[0003] In the prior art, prefabricated buildings can be divided into reinforced concrete prefabricated buildings and steel structure prefabricated buildings. The steel beams and steel columns of steel structure prefabricated buildings are divided into H-shaped steel beams and steel columns and box-shaped steel beams and steel columns. The beam-column joints of H-shaped steel beams and steel columns are mostly welded on site, and the construction process is still mostly wet work, with low assembly efficiency and poor safety.

[0004] In the design of building steel structures, steel columns often use a cross-shaped box structure, with a "field" formed in the variable cross-section area. The field of some components is relatively long, with the longest field being 2-3 meters. There are many parts in this "field" area, and the parts need to be assembled multiple times, which makes the on-site assembly and welding work complicated and arduous. The cross-shaped box has a small cross section, and the quality of deep welding inside the box cannot be guaranteed. During on-site assembly, it is only connected by nesting or bolting, resulting in uneven force on the steel beam. Over time, cracks will appear in the beam-column node, or even breakage, so that subsequent repair and maintenance are required in the project.

[0005] Therefore, in order to solve the above technical problems, a cross and box-type column conversion structure and a conversion connecting component are specially proposed to improve the strength of the beam-column node, speed up the construction speed, improve the assembly efficiency, ensure the safety of the beam-column node, and reduce subsequent maintenance.
