Description

Technical Field

[0002] Steel structure buildings have the advantages of light weight, high strength, good plasticity and toughness, and are widely used in building structure design. The bearing capacity and applicability of steel structures depend to a large extent on the connection strength between steel structures and concrete embedded parts. In order to ensure the safety and practicality of building structures, the connection structure between steel structures and concrete embedded parts is particularly important.

[0003] Prior art CN217652011U proposes a pre-buried connection structure between a steel structure and concrete. By rotating the connecting piece, the connecting piece rotates with the rotating shaft as the center, and the rotating rod is also driven to rotate downward. When it is rotated to the point where the connecting rod can be clamped onto the hook plate, the connecting piece is rotated in the opposite direction. At this time, the connecting piece is restricted by the hook plate and rotates with the connecting rod as the center until the bottom of the connecting piece clamps the protrusions on both sides of the fixed plate to complete the locking. It can maintain stability and is easy to operate, and is convenient for setting.

[0004] In the prior art, when installing and connecting steel structures, bolts are usually used for fixing. However, during installation, multiple bolts are usually required for fixing, which is relatively troublesome during installation. Utility Model Content
