Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically to a heat-insulating fire door core panel structure. 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 an important part of building fire protection measures. Fire doors must be installed at the fire compartments of evacuation routes in buildings to ensure that people can easily evacuate in the event of a fire, and that the fire doors can prevent the spread of fire from the affected area to adjacent fire compartments when closed. They are an indispensable part of building fire protection facilities. Nowadays, wooden fire doors are widely favored by the market because of their advantages such as lightweight, beautiful appearance, and ease of processing.

[0003] In the process of realizing this utility model, the inventors discovered the following unresolved problems in the prior art: the existing heat-insulating fireproof door core panel structure is an outer iron plate. After applying adhesive to the iron plate and the fireproof rock wool core panel, the iron plate and the core panel are bonded together. However, during long-term use, if the iron plate or the core panel is damaged, the core panel is bonded together with adhesive, which is not conducive to later disassembly and recycling. Therefore, we propose a heat-insulating fireproof door core panel structure. Utility Model Content

[0004] The purpose of this utility model is to provide a heat-insulating and fireproof door core panel structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating and fireproof door core panel structure, including a shell, an opening integrally formed on the rear side of the shell, and a side plate placed at the opening; The shell has an integrally formed inner cavity, and a fireproof rock wool core board is positioned in the middle of the inner cavity. A threaded groove is opened in the middle of the front side of the top wall of the shell. The inner walls on both sides of the housing are provided with a locking block a, and there are four sets of locking blocks a. The locking blocks a are located in the opening area, and a locking block b is provided in the middle of the bottom wall of the housing. Both the card block a and the card block b are provided with plate grooves, and the outline of the plate grooves is adapted to the shape of the side plate. A screw rod is movably inserted through the top of the side plate. The rear end of the screw rod is screwed into a pre-set threaded groove on the top wall of the housing via an external thread. It can be used in conjunction with components such as the side plate, locking blocks, and screw rod. During the use of the fire door core panel structure, the fireproof rock wool core panel can be inserted into the inner cavity by opening the side plate. Then, the side plate is inserted into the opening, so that its two sides are locked in the plate groove of locking block a, and its bottom is locked in the plate groove of locking block b. Then, the screw rod is inserted and screwed into the threaded groove to realize the assembly of the fire door. It adopts a non-adhesive bonding method for assembly. If the housing or core panel is damaged later, the core panel or housing can be recycled separately. The non-adhesive design facilitates disassembly later.

[0006] As an optional solution to the technical solution of this application, the housing has a limiting groove on the side near the locking block a and the locking block b. A limiting block is locked in the limiting groove. The locking block a and the locking block b are fixedly connected to the limiting block on the same side. They can be used in conjunction with the limiting block and the limiting groove. Since the limiting block is locked in the limiting groove, if the housing is damaged later, the locking block a and the locking block b can be moved by force after the side plate is removed. The locking blocks on the housing can be disassembled and recycled, which can reduce the replacement cost of the housing mechanism later.

[0007] As an optional solution to the technical solution of this application, an indicator sign is fixedly installed on the top of the outer wall of the housing, and the indicator sign is fixed by welding. The guide text on the indicator sign can introduce and promote the product, and can also be used to explain the disassembly and assembly process, which meets the usage requirements.

[0008] As an optional solution to the technical solution of this application, the contour of the inner cavity is adapted to the shape of the fireproof rock wool core board, and the side plate abuts against one side of the fireproof rock wool core board. Through the adaptation and abutment design, obvious shaking can be prevented during use, making it more ideal to use.

[0009] As an optional solution to the technical solution of this application, a recess is provided on the outer side of the end of the side plate near the screw, and the end of the screw is completely located in the recess. The screw end can be housed by the recess, which can prevent it from protruding outward, thereby avoiding scratching foreign objects or people during use.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model discloses a fireproof and heat-insulating door core panel structure. By incorporating side plates, locking blocks, and screws, during use, the fireproof rock wool core panel can be inserted into the inner cavity by opening the side plates. The side plates are then inserted into the opening, with their sides locked in the grooves of locking block a and their bottom locked in the grooves of locking block b. The screws are then inserted through and screwed into the threaded groove, enabling the assembly of the fireproof door. This non-adhesive assembly method allows for the separate recycling of the core panel or core panel if the shell or core panel is damaged later. The non-adhesive design facilitates disassembly.

[0011] 2. The present invention provides a heat-insulating and fireproof door core panel structure. By setting limit blocks and limit grooves, since the limit blocks are locked in the limit grooves, if the shell is damaged later, the locking blocks a and b can be moved by force after the side panel is disassembled, and the locking blocks on the shell can be disassembled and recycled, which can reduce the replacement cost of the shell mechanism later.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figure 1-4This utility model provides a technical solution: a heat-insulating and fireproof door core panel structure, including a shell 1. An indicator sign 11 is fixedly installed on the top of the outer wall of the shell 1, and the indicator sign 11 is fixed by welding. The guide text on the indicator sign 11 can introduce and promote the product, and can also be used to explain the disassembly and assembly process, meeting the usage requirements. An opening 2 is integrally formed on the rear side of the shell 1, and a side plate 3 is placed at the opening 2. An inner cavity 12 is integrally formed inside the shell 1, and a fireproof rock wool core panel 13 is inserted in the middle of the inner cavity 12. The outline of the inner cavity 12 is adapted to the shape of the fireproof rock wool core panel 13, and the side plate 3 abuts against one side of the fireproof rock wool core panel 13. Through the adaptive abutment design, significant shaking can be prevented during use. For better usability, a threaded groove 14 is provided in the middle of the front side of the top wall of the housing 1; a locking block a4 is provided on both inner walls of the housing 1, and there are four sets of locking blocks a4. The locking blocks a4 are located in the area of ​​the opening 2, and a locking block b41 is provided in the middle of the bottom wall of the housing 1; a plate groove 42 is provided in both the locking blocks a4 and the plate groove 42 is adapted to the shape of the side plate 3; a screw 31 is movably passed through the top of the side plate 3, and a recess 32 is provided on the outer side of the end of the side plate 3 near the screw 31, and the end of the screw 31 is completely located in the recess 32. The end of the screw 31 can be stored in the recess 32 to prevent it from protruding outward, thereby avoiding scratching foreign objects or people during use. The rear end of the screw 31 is screwed into the threaded groove 14 pre-set on the top wall of the housing 1 through the external thread.

[0016] In this technical solution, components such as side plate 3, locking blocks, and screw 31 can be used together. During the use of the fire door core panel structure, the fireproof rock wool core panel 13 can be inserted into the inner cavity 12 by opening the side plate 3. Then, the side plate 3 is inserted into the opening 2, so that its two sides are locked in the plate groove 42 of the locking block a4, and its bottom is locked in the plate groove 42 of the locking block b41. Then, the screw 31 is passed through and screwed into the threaded groove 14, which can realize the assembly of the fire door. The non-adhesive bonding method is used for assembly.

[0020] When a heat-insulating fireproof door core panel structure is used, the fireproof door with the core panel structure is transported to the designated area and then assembled on the door frame by hinges. During this process, the heat-insulating and fireproof effect can be provided by the shell 1 and the fireproof rock wool core panel 13. By incorporating a side plate 3, locking blocks, and a screw 31, the fireproof rock wool core board 13 can be inserted into the inner cavity 12 by opening the side plate 3 during the use of the fireproof door core board structure. Then, the side plate 3 is inserted into the opening 2, with its sides locked in the slots 42 of the locking blocks a4 and its bottom locked in the slots 42 of the locking blocks b41. The screw 31 is then inserted and screwed into the threaded groove 14, thus assembling the fireproof door. This non-adhesive assembly allows for separate recycling of the core board or core board if the shell 1 or core board is damaged later. The non-adhesive design facilitates disassembly. With a limiting block 51 and a limiting groove 5, the limiting block 51 is locked in the limiting groove 5. If the shell 1 is damaged later, the locking blocks a4 and b41 can be moved after the side plate 3 is removed, allowing for disassembly and recycling of the locking blocks on the shell 1, reducing the cost of replacing the shell 1 mechanism later.
