Description

Technical Field

[0001] The utility model relates to the field of building embedded parts, in particular to a combined buckling restraint support embedded part. Background Art

[0002] Frame structures and frame-and-braced structures are widely used in modern architecture. However, pure frame structures have limited lateral stiffness and experience significant lateral displacement under earthquakes and strong wind loads, limiting their application. Frame-and-braced structures address this issue of lateral stiffness to a certain extent, but they are prone to buckling under compression under strong earthquakes, which can easily damage or fail the supports or connections, reducing the structure's seismic performance.

[0003] To address the problem of brace buckling under compression and improve the structure's seismic energy dissipation capacity, buckling-restrained braces are currently incorporated into frame structures. When external forces act on the braces, the core slab yields under the restraints of the external casing, but buckling instability does not occur. This design allows the braces to enter the yield stage under both tension and compression, thereby achieving hysteretic energy dissipation. That is, under repeated loads, the braces can absorb and dissipate energy, improving the structure's overall seismic resistance.

[0004] During the installation process of the buckling restraint support device, embedded parts need to be installed in the beam and column reinforcement. However, the web strips of the embedded parts are currently equipped with end plates, and the anchor rods are welded and fixed to the web strips. During installation, the on-site beam and column reinforcement projects have been tied in place, and the stirrup spacing in the reinforcement projects is small. The obstruction of the end plates and anchor rods makes it difficult to insert the embedded parts into the reinforcement projects, affecting construction efficiency and making it impossible to ensure that the embedded parts are accurately installed. This needs to be improved. Utility Model Content

[0007] Preferably, the middle portion of the web strip is provided with light holes having the same number as the anchor rod B, the light holes pass through the web strip transversely, and the anchor rod B is matched and inserted into the light holes.

[0008] Preferably, the middle part of the web strip is provided with threaded holes with the same number as the anchor rod B, and the middle part of the anchor rod B is coaxially provided with a cylindrical boss with a diameter larger than that of the anchor rod B.

[0009] Preferably, one end of the cylindrical boss is provided with a limiting ring whose size is larger than that of the threaded hole.

[0011] Preferably, the number of the anchor rods A and the number of the web strips are the same and their positions correspond to each other.

[0012] Preferably, the seat plate and the web strips are both square plates, and the size of the seat plate is larger than that of the web strips.

[0013] Preferably, a pair of circular limit blocks are coaxially provided on the upper end of the anchor rod A, and the vertical drop of the limit blocks is larger than the size of the anchor rod A.
