TECHNICAL FIELD

[0001] The utility model relates to the technical field of old building maintenance, specifically to an anti-seismic steel structure connecting piece. BACKGROUND

[0002] In the field of steel structure buildings, the anti-seismic performance is crucial. In order to improve the anti-seismic ability, various anti-seismic connecting pieces have emerged in an endless stream, but the existing design still has deficiencies. The traditional anti-seismic connecting piece has a complex structure, is inconvenient to install, and has poor connection stability under extreme conditions, especially at the connection between the support column and the H-shaped beam.

[0003] To improve this situation, researchers have proposed a new connecting piece containing a support column, an H-shaped beam and an anti-seismic connecting structure. However, this design still has limitations in adjustability and adaptability, making it difficult to adapt to components of different sizes and shapes, and the installation and disassembly are cumbersome, which is not conducive to on-site construction. The existing anti-seismic connecting structure contains fixed connecting parts, which requires accurate alignment during installation, making the operation difficult, and it is difficult to adjust or replace individually after installation.

Therefore, there is an urgent need for a new anti-seismic steel structure connecting piece that has the characteristics of simple structure, convenient installation, strong adjustability, good adaptability and superior anti-seismic performance.

When the horizontal extrusion threaded rod extends or retracts, it drives the extrusion concave block on it to move.

During this process, the extrusion sleeve spring 17 plays a role in buffering and shock absorption, while the extrusion limiting shaft ensures the stable movement of the extrusion convex block.
