[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] This invention provides a door frame structure and a fire door with sealing, fireproofing, and heat insulation properties. By optimizing the internal and external structure of the fire door frame, the overall sealing, fireproofing, and heat insulation performance of the fire door are improved, while also enhancing the adaptability of the door frame to walls of different sizes. Examples

[0029] Figure 1 shows a structural schematic diagram of a door frame structure with sealing and fireproof heat insulation properties according to the present invention. Referring to Figure 1, a door frame structure with sealing and fireproof heat insulation properties according to this embodiment includes a composite mixed wood board 100, a mixed wood splice door frame 200, a fireproof board 300, and a medium fiberboard covered with PVC decorative panel 400.

[0030] The composite mixed wood board 100 consists of two pieces, which serve as the main load-bearing structure, possessing high compressive strength and stability to ensure the overall strength of the door frame during long-term use.

[0031] The mixed wood panel door frame 200 is wrapped between two composite mixed wood panels 100 and on the outer wall of the composite mixed wood panel 100 on the left side. The mixed wood panel door frame 200 further enhances the structural stability of the door frame through tight bonding, while improving the door frame's resistance to deformation and maintaining good dimensional stability under different environmental conditions.

[0032] Fireproof board 300 covers the outer wall of the right-side mixed wood panel door frame 200 and the outer wall of the right-side composite mixed wood panel 100. Fireproof board 300 is made of high-efficiency flame-retardant material and has a moderate thickness. It can effectively block heat transfer under high temperature conditions, thereby providing heat insulation and fire protection for the internal structure of the door frame and improving the overall fire resistance of the door frame.

[0033] A medium-density fiberboard (MDF) covered with a PVC decorative panel 400 is installed on the outer wall of the fireproof board 300. This MDF-covered PVC decorative panel 400 serves as the outermost layer of the door frame and is tightly bonded to the fireproof board 300 via a hot-pressing process, providing a smooth decorative appearance while offering excellent moisture resistance and durability. This decorative layer not only enhances the overall aesthetics of the door frame but also seals off the internal structure, preventing external environmental corrosion of the internal materials.

[0034] The composite mixed wood board 100 has a first groove 110 on its upper part and a second groove 120 on its lower part. The first groove 110 is used to connect the sealing component 30, and the second groove 120 is used to connect the door frame panel 20. (Example)

[0035] Figures 2 and 3 show the structural schematic diagram of a fire door with sealing and fireproof heat insulation performance according to the present invention. Referring to Figures 2 and 3, a fire door with sealing and fireproof heat insulation performance according to this embodiment includes a door frame structure 10 with sealing and fireproof heat insulation performance, a door sleeve plate 20, a sealing component 30, and a door leaf 50.

[0036] The door frame panel 20 is partially embedded in the second groove 120 of the composite mixed wood board 100. Specifically, the door frame panel 20 includes a medium-density fiberboard (MDF) PVC-coated panel 210 and a MDF 220. The MDF PVC-coated panel 210 serves as the outer surface of the door frame panel 20. By fitting into the second groove 120, the door frame panel 20 can be stably installed on the door frame structure 10, while improving the overall appearance consistency between the door frame and the door frame panel. The MDF 220 serves as the internal support of the door frame panel 20, ensuring the strength and durability of the door frame panel 20. The design of the door frame panel 20 is easy to adapt to walls of different thicknesses, enabling the door frame to be quickly assembled, simplifying the installation process, and improving installation efficiency.

[0037] The sealing components 30 are embedded one-to-one in the first groove 110 of the composite wood board 100 and the groove of the door frame 20 to form an integrated connection structure. The sealing components 30 are tightly fitted to the wall 40, thereby achieving efficient connection and sealing performance between the door frame structure 10 and the wall 40.

[0038] Door leaf 50 is positioned between two door frame structures 10.

[0039] In this embodiment, a fire-resistant expansion sealing strip 60 and an insertable anti-collision strip 70 are also included. The fire-resistant expansion sealing strip 60 is embedded at the connection between the door frame structure 10 and the door leaf 50 to block the spread of smoke and flames and ensure the sealing of the connection between the door frame structure 10 and the door leaf 50. The insertable anti-collision strip 70 is set at the edge where the door frame structure 10 and the door leaf 50 contact each other. It effectively buffers the impact force when the door leaf is closed through elastic material, and at the same time improves the fit between the door frame and the door leaf.

[0040] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
