[0002] With the acceleration of urbanization and the continuous emergence of complex projects such as high-rise buildings and large-span structures, earthquake-resistant design has become an indispensable part of architectural design and engineering. Earthquakes, as a highly destructive natural disaster, pose a serious threat to building structures and human life and property safety. Therefore, improving the earthquake resistance of building structures and reducing the losses caused by earthquake disasters have become urgent issues to be solved in the fields of architectural design and engineering.

[0003] At present, load-bearing vertical poles, load-bearing cross bars and diagonal braces are widely used in building structures, and the connection of their main components depends on the bite friction between the channel steel teeth and the nut tooth grooves. However, with the gradual increase of seismic loads, these connection points face severe challenges. Specifically, the channel steel teeth and the rotor nut tooth grooves are gradually worn flat under the continuous earthquake action, and the bite friction is gradually lost, which eventually leads to the failure of the connection node, thereby significantly reducing the performance of the entire support system. There is also a common connection method, which is to open through holes on the channel steel according to needs and use nuts to connect the diagonal brace rods. However, the accuracy of opening through holes in the channel steel of this technical solution is completely dependent on manual labor, which is very easy to cause structural deviation, and each connection of the diagonal brace rod connector is very cumbersome and the construction efficiency is low. Now we continue to design an earthquake-resistant diagonal brace structure that can be universally applied and does not require repeated openings. Utility Model Content
