[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods. A search revealed application number CN202320462846.1, which discloses a prefabricated building mezzanine structure. The structure includes an upper building panel, a mezzanine panel attached to the bottom of the upper panel, and a lower building panel attached to the bottom of the mezzanine panel. Connecting sleeves are fixedly connected to both sides of the upper and lower building panels. A rod is inserted into the top of each connecting sleeve, extending to the bottom of the inner wall of the connecting sleeve. A rotating block is located on the outer side of the connecting sleeve, and a screw is fixedly connected to the inner side of the rotating block. The inner side of the screw is movably connected to the inner wall of the connecting sleeve via a bearing. A transmission plate is threaded onto the surface of the screw, and a locking rod is fixedly connected to the right side of the transmission plate. This invention enhances the functionality of facilitating the installation of the building mezzanine, enabling quick fixing of the mezzanine panel and easy disassembly, thus preventing difficulties in installing prefabricated building mezzanines.

The surface of the concave bracket 21 is provided with a sliding groove 22, and the surface of the sliding groove 22 is provided with an abutment bracket 23.

[0018] The concave bracket 21 and the sliding groove 22 are adapted to slide against each other, changing the specific position of the abutment bracket 23.
