Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to an adjustable building steel structure connector. Background Art

[0002] Steel structure building is a new type of building system. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete. They have a simple structure and are easy to make. Since steel structure components can be manufactured in factories and installed on site, the construction period is greatly shortened. Steel can be reused, which reduces construction waste and is more environmentally friendly. Therefore, it is widely used in industrial and civil buildings. Steel structures require connectors to splice and install steel parts. Existing building steel structure connectors still have certain defects when used, such as;

[0003] Most of the existing building steel structure connectors cannot adjust the angle during installation and use. When encountering some steel parts with a certain angle, they cannot meet the angle adjustment requirements. Most of them cannot adjust the angle. At the same time, when the external environment changes and causes thermal expansion and contraction, the impact on the steel structure is relatively large, and most of the existing building steel structures cannot reduce the impact caused by thermal expansion and contraction. In addition, most of the existing building steel structure connectors are fixed in length. When installing with steel parts, if the distance is a little different, only part of the steel parts can be welded, and most of them cannot be extended. Utility Model Content
