Description

Technical Field

[0001] This utility model relates to the field of door technology, specifically to an integrated fireproof and soundproof door with anti-deformation function. Background Technology

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance installed in fire compartments, evacuation stairwells, vertical shafts, etc. They are specifically used in buildings to isolate fire sources and play a huge role in fire protection. In the event of a fire, people can get an escape opportunity through fire doors.

[0003] However, existing integrated fireproof and soundproof doors still have some problems:

[0004] An existing soundproof and fireproof door, such as one with application number CN201820663495.X, includes a door frame and a door panel. The door frame is fastened to the perimeter of the door panel. The door panel includes an inner panel and an outer panel. A fireproof board and a soundproof board are provided between the inner panel and the outer panel. The fireproof board is composed of an inner fireproof board and an outer fireproof board. The inner fireproof board is placed on the inner panel, and the outer fireproof board is placed on the outer panel. Several diagonal plates are intersected between the inner fireproof board and the soundproof board, and several reverse diagonal plates are placed between two adjacent diagonal plates. The diagonal plates and the reverse diagonal plates form several diamond-shaped grid holes.

[0005] Existing fireproof and soundproof integrated doors are prone to deformation under the influence of environmental factors such as high temperature and humidity. This leads to an increase in the gap between the door and the door frame, which not only reduces the fireproof and soundproof effect, but may also affect the normal opening and closing of the door, posing certain safety hazards.

[0006] Therefore, we propose an integrated fireproof and soundproof door with anti-deformation function to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to provide a fireproof and soundproof integrated door with anti-deformation function, so as to solve the problem mentioned in the background art that the fireproof and soundproof integrated door is prone to deformation under the influence of environmental factors such as high temperature and humidity, which leads to the increase of the gap between the door and the door frame. This not only reduces the fireproof and soundproof effect, but may also affect the normal opening and closing of the door, posing certain safety hazards.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fireproof and soundproof integrated door with anti-deformation function, comprising a door frame and hinges:

[0009] The outer surface of the door frame is bolted with hinges. A door body is provided in the middle of the door frame and rotatedly connected by the hinges. A sound insulation board is attached to the inner surface of the door body. The interior of the door body is filled with a composite filling layer. Several positioning holes are provided on the four sides of the sound insulation board and the composite filling layer. Triangular brackets are installed at the four corners of the door body. Three sides of the brackets are threaded with a second screw. A sealing groove is provided on the inner side of the door frame. A sealing strip that matches the sealing groove is installed at the rear edge of the door body.

[0010] By adopting the above technical solution, sound insulation panels and composite filling layers are set inside the door body, and precise assembly is achieved using positioning holes. Combined with the triangular brackets at the four corners of the door body, good fireproof and sound insulation performance and deformation resistance are achieved. At the same time, the sealing groove on the inner side of the door frame and the sealing strip on the edge of the door body fit together tightly, effectively improving the sealing effect and further enhancing the fireproof and sound insulation functions.

[0011] Preferably, the door frame has an internal filling cavity, which is filled with a number of reinforcing ribs, and the reinforcing ribs are designed in a crisscross pattern.

[0012] By adopting the above technical solution, a filling cavity is opened inside the door frame, and reinforcing ribs are filled inside the filling cavity in a crisscross pattern. This effectively improves the door frame's ability to resist external deformation and ensures that the door frame can maintain a stable shape and structural strength even after long-term use or under the influence of impact, high temperature and other environmental factors. This provides a solid support foundation for the door and ensures the normal opening and closing and sealing performance of the door.

[0013] Preferably, the door body includes a first fireproof plate, with internally threaded posts fixed on the four sides of the interior of the first fireproof plate, and a second fireproof plate provided on the other side of the first fireproof plate. The outer surface of the second fireproof plate is provided with screw holes corresponding to the internally threaded posts, and a first screw is threaded through and threaded to the middle of the screw holes and the internally threaded posts.

[0014] Using the above technical solution, the door body is composed of a first fireproof board and a second fireproof board spliced ​​together. The first fireproof board and the second fireproof board are firmly combined by the threaded fastening of the internal threaded post, threaded hole and first screw, which enhances the overall strength and stability of the door body and improves the fire resistance of the door body.

[0015] Preferably, the composite filling layer includes a first fireproof and heat-insulating layer, a reinforcing support layer is attached to one side of the first fireproof and heat-insulating layer, and a second fireproof and sound-insulating layer is attached to one side of the reinforcing support layer.

[0016] Using the above technical solution, the composite filling layer is composed of a first fireproof and heat-insulating layer, a reinforcing support layer, and a second fireproof and sound-insulating layer in sequence. The first fireproof and heat-insulating layer effectively blocks heat, the reinforcing support layer enhances the door's resistance to deformation, and the second fireproof and sound-insulating layer improves sound insulation and fire resistance. The combination of the three significantly improves the door's fireproof and heat-insulating, sound insulation, and structural stability.

[0017] Preferably, the first fireproof and heat-insulating layer is composed of rock wool board and aluminum foil reflective material, the reinforcing support layer is composed of several high-strength fiber skeletons interwoven, and the second fireproof and sound-insulating layer is composed of melamine foam and glass wool.

[0018] Using the above technical solution, the first fireproof and heat-insulating layer combines the heat insulation performance of rock wool board with the heat reflection characteristics of aluminum foil reflective material to effectively block heat transfer and improve the fireproof and heat-insulating effect. The reinforced support layer forms a stable mechanical structure through a crisscrossing high-strength fiber skeleton, which enhances the structural strength of the door and prevents deformation. The second fireproof and sound-insulating layer combines the sound absorption properties of melamine foam with the fireproof and sound-absorbing properties of glass wool to effectively absorb sound waves and block fire, significantly enhancing the fireproof, sound-insulating performance and structural stability of the door, meeting safety and practical needs.

[0019] Preferably, the second screw, which is threaded and extends through three sides of the bracket, corresponds to the first fireproof and heat-insulating layer, the reinforcing support layer, and the second fireproof and sound-insulating layer, respectively.

[0020] By adopting the above technical solution, the three sides of the triangular bracket are threadedly connected to the different functional layers of the composite filling layer by the second screw, which enhances the structural strength and stability of the four corners of the door, effectively resists the deformation caused by external impact and environmental factors, and ensures that the relative positions of each functional layer of the composite filling layer remain fixed during use, so as to continuously perform fireproof, heat insulation and sound insulation properties.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By setting sound insulation panels and composite filling layers inside the door, precise assembly is achieved using positioning holes, and combined with triangular brackets at the four corners of the door, good fireproof and sound insulation performance and deformation resistance are achieved. At the same time, the sealing groove on the inner side of the door frame and the sealing strip on the edge of the door fit together tightly, effectively improving the sealing effect and further enhancing the fireproof and sound insulation function.

[0023] 2. An infill cavity is opened inside the door frame, and reinforcing ribs are filled inside the infill cavity in a crisscross pattern. This effectively improves the door frame's ability to resist external deformation and ensures that the door frame can maintain a stable shape and structural strength even after long-term use or under the influence of impact, high temperature and other environmental factors. This provides a solid support foundation for the door and ensures the normal opening and closing and sealing performance of the door. Attached Figure Description

Three sides of the brackets 7 are threaded through and connected with second screws 8. A sealing groove 9 is opened on the inner side of the door frame 1. A sealing strip 10 adapted to the sealing groove 9 is installed at the rear edge of the door body 3. A filling cavity 101 is opened inside the door frame 1. The filling cavity 101 is filled with several reinforcing ribs 102, and the reinforcing ribs 102 are designed in a crisscross pattern. The door body 3 includes a first fireproof plate 301. The four sides of the interior of the first fireproof plate 301 are fixed with internal threaded posts 302. A second fireproof plate 303 is provided on the other side of the first fireproof plate 301. The outer surface of the second fireproof plate 303 is provided with screw holes 304 corresponding to the internal threaded posts 302. The screw holes 304 and the internal threaded posts 302 pass through each other and are threadedly connected with a first screw 305.

[0032] The door frame 1 and door body 3 are rotatably connected by hinge 2 to form a basic opening and closing structure. The crisscrossing reinforcing ribs 102 inside the filling cavity 101 of the door frame 1 can enhance the overall rigidity of the door frame 1 to a certain extent. The door body 3 is composed of a first fireproof board 301 and a second fireproof board 303. The second fireproof board 303 and the first fireproof board 301 are fastened together by internally threaded posts 302, screw holes 304, and first screws 305 to form the door body 3, enhancing the overall strength of the door body 3 and improving its fire resistance. The first fireproof board 301 and the second fireproof board 303... Sound insulation panels 4 are pasted on the inner side of the door 3. The sound insulation panels 4 are tightly attached to the inner walls of the two sets of fireproof panels through the positioning holes 6 to achieve the sound insulation function. The triangular brackets 7 at the four corners of the door 3 are first fastened to the four corners of the door 3 with the help of the second screws 8 to increase the anti-deformation ability. The sealing groove 9 on the inner side of the door frame 1 is tightly matched with the sealing strip 10 on the edge of the door 3 to improve the sealing performance and significantly enhance the overall anti-deformation ability of the door 3. This allows the door to maintain its structural integrity under high temperature and external impact, effectively improving the fire resistance and sound insulation performance of the door 3 and meeting the dual requirements of building safety and user comfort.

[0033] The composite filling layer 5 includes a first fireproof and heat-insulating layer 501, a reinforcing support layer 502 attached to one side of the first fireproof and heat-insulating layer 501, and a second fireproof and sound-insulating layer 503 attached to one side of the reinforcing support layer 502.

A second screw 8, threaded and connected to three sides of the bracket 7, corresponds to the first fireproof and heat-insulating layer 501, the reinforcing support layer 502, and the second fireproof and sound-insulating layer 503, respectively.

[0034] The first fireproof and heat-insulating layer 501 is a composite of rock wool board and aluminum foil reflective material. The rock wool board, with its porous structure, blocks heat conduction, while the aluminum foil reflective material, with its high reflectivity, reflects heat away. Together, they achieve highly efficient fireproof and heat-insulating properties. The reinforcing support layer 502 is composed of a high-strength fiber skeleton arranged in a crisscross pattern. Utilizing the high strength of the fiber material, the interwoven structure forms a stable structure, providing reliable support for the door 3. The second fireproof and sound-insulating layer 503 is a composite of melamine foam and glass wool. The porous structure of the melamine foam absorbs sound wave energy, while the glass wool... With fireproof and sound-absorbing functions, it achieves the dual effects of fireproofing and sound insulation. At the same time, the triangular brackets 7 at the four corners of the door body 3 are threadedly connected to the first fireproof and heat-insulating layer 501, the reinforcing support layer 502, and the second fireproof and sound-insulating layer 503 respectively by the second screws 8. With the tightening force of the screws, the brackets 7 are tightly combined with the composite filling layer 5 to form a stable whole. This not only improves the fireproof, heat-insulating, and sound-insulating performance of the door body 3, but also enhances the structural strength and deformation resistance of the door body 3, effectively resisting the impact of external forces and environmental factors, and ensuring that the door body 3 can function stably for a long time under various working conditions.

[0035] Working principle: For this type of fireproof and soundproof integrated door with anti-deformation function, the crisscrossing reinforcing ribs 102 in the filling cavity 101 inside the door frame 1 enhance the overall rigidity.

The soundproof plate 4 on the inner surface of the door body 3 and the composite filling layer 5 are precisely assembled through the positioning hole 6. In the composite filling layer 5, the first fireproof and heat-insulating layer 501 is composed of rock wool board and aluminum foil reflective material. The fireproofing is achieved by using the heat insulation of the rock wool board and the heat reflection of the aluminum foil. The heat insulation and reinforced support layer 502 is a stable structure formed by the crisscrossing of high-strength fiber skeleton to provide support. The second fireproof and soundproof layer 503 is a composite of melamine foam and glass wool to achieve sound absorption and fireproof functions. The triangular brackets 7 at the four corners of the door body 3 are connected to each layer of the composite filling layer 5 by the second screws 8 to further reinforce the door body 3. The sealing groove 9 on the inner side of the door frame 1 and the sealing strip 10 on the edge of the door body 3 are tightly fitted to ensure that the door body 3 can effectively enhance its anti-deformation ability on the basis of opening and closing function. At the same time, with the multi-layer structure and sealing design, it achieves excellent fireproof and soundproof performance.
