Description

Technical Field

[0001] This utility model relates to the field of wall beam-column joints, and in particular to a steel plate wall beam-column connection joint. Background Technology

[0002] In recent years, prefabricated buildings have developed rapidly. Most prefabricated buildings require the prefabrication of the main structure, such as prefabricated concrete shear walls. At the joints between adjacent prefabricated walls or between prefabricated walls and other structures, steel reinforcement binding is required, and formwork is erected at the joints for concrete pouring. Although this greatly shortens the construction period and reduces the amount of wet work compared to cast-in-place shear wall construction, it increases the construction at the joints, especially at the joints between structural columns and shear walls and connecting beams, where steel reinforcement binding is more complicated and it is not easy to control the construction quality.

[0003] Based on this, the existing technology proposes to use a combination of steel plate shear walls and steel columns. However, this requires welding and fixing the steel columns to the steel plate walls and steel connecting beams. Although this eliminates the need for rebar tying, it brings a large amount of welding work, and the welding quality cannot be well guaranteed. This will have a certain impact on the strength of the structure and bring some risks. Utility Model Content
