Description

Technical Field

[0001] This utility model relates to the field of fireproof door frame technology, and in particular to a fireproof door frame structure that is easy to assemble. Background Technology

[0002] Traditional fire door frame structures are mostly assembled using bolt fixing or welding, resulting in low construction efficiency and difficulties in disassembly and maintenance. Especially in high-rise buildings or emergency construction scenarios, traditional methods rely on numerous fasteners, making installation cumbersome and prone to deformation and poor sealing due to human error, thus affecting fire resistance. Furthermore, existing door frames lack modularity, making alignment difficult, and requiring complete disassembly for later repairs or replacements, increasing maintenance costs. While some designs attempt to simplify the structure, they lack reliable locking mechanisms, allowing gaps to form at door frame joints due to thermal expansion or external impacts, leading to a decrease in fire resistance and insulation. Therefore, we propose a fire door frame structure that is easy to assemble. Utility Model Content

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a fireproof door frame structure that is easy to assemble.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a fireproof door frame structure that is easy to assemble, including two door frames. The door frames are U-shaped blocks and the two door frames are mirror images of each other. Each of the two door frames has a first mounting groove on its corresponding end face. A pull block is fixedly installed inside each of the two corresponding first mounting grooves. The pull block is an arc-shaped block. A sliding mounting post is provided inside the first mounting groove. A first pull plate buckle adapted to the pull block is fixedly installed on the side of the mounting post. The first pull plate buckle hooks on the side of one pull block. Rotating posts are rotatably installed at both ends of the mounting post.

[0005] Preferably, the mounting post has a guide hole on its side, and a connecting post is fixedly installed on the side of the first mounting groove corresponding to the position of the mounting post. The connecting post passes through the interior of the guide hole, and the mounting post is slidably installed on the connecting post through the guide hole. A compression nut is threadedly connected to the side of the connecting post corresponding to the lower part of the mounting post.

[0006] Preferably, one of the two door frames has a guide groove on one side and a guide block is fixedly installed on the other side, with the guide block slidably installed inside the guide groove.

[0011] This utility model provides a fireproof door frame structure that is easy to assemble. It has the following beneficial effects:

[0012] (1) This easy-to-assemble fireproof door frame structure achieves rapid alignment and locking of the door frame through a mirror-symmetrical "U"-shaped door frame design and matching first pull plate buckle, second pull plate buckle and pull block structure. During installation, simply align the two door frames, use the mounting column to drive the rotating column to rise, so that the pull plate buckle hooks are hooked on the side of the pull block, forming a bidirectional tension force, forcing the two door frames to fit together towards the center. This process ensures accurate alignment through the pre-positioning cooperation of the guide groove and guide block; combined with the thread adjustment function of the compression nut, the locking force can be finely adjusted, avoiding deformation caused by manual hammering, and significantly improving assembly efficiency and structural stability.

[0013] (2) This easily assembled fireproof door frame structure features a first and second retaining plate at the door frame joint, using an interference fit to effectively seal the installation groove gaps and prevent the spread of fire. Fireproof foam adhesive is further injected between the two retaining plates through the injection hole to fill the internal cavity of the door frame, forming a continuous insulation layer. The design of the inclined arc-shaped pull block and the "J"-shaped pull plate buckle generates radial clamping force when locked, enhancing the airtightness of the joint. Combined with the overall integrity after the foam adhesive has cured, this significantly improves the fire resistance limit and meets the fire protection requirements of high-rise buildings.
