Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically a double-leaf wooden insulated fire door. 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] Currently, double-leaf fire doors are made by pressing a single flame-retardant board and a heat-insulating board together. In the event of a fire, the heat is only insulated by the heat-insulating board, which allows heat to be transferred quickly and cause the temperature of the unexposed side to rise excessively. At the same time, the double-leaf door has a large area and lacks a protective structure for the internal materials. When an explosion occurs during a fire, the resulting fragments damage the interior of the double-leaf door, allowing heat to be transferred quickly to the back of the fire door, further aggravating heat penetration and reducing the heat insulation effect of the fire door. Therefore, we need to propose a double-leaf wooden heat-insulated fire door. Utility Model Content

[0004] The purpose of this utility model is to provide a double-leaf wooden fireproof door. The combination of magnesium oxide board and flame-retardant board improves the flame-retardant and heat-insulating effect of the wooden fireproof door. The heat insulation effect of the wooden fireproof door is further enhanced by the setting of the heat insulation layer. The heat insulation and flame-retardant structure of the wooden fireproof door can be protected by the setting of the protective structure. When an explosion occurs during a fire, the resulting fragments will only come into contact with the protective structure. The above solution improves the heat insulation effect of the double-leaf wooden fireproof door, avoids damage to the internal structure of the fireproof door during an explosion, reduces the speed at which heat is transferred to the back of the fireproof door, and reduces the heat penetration rate, thereby solving the problems mentioned in the background art.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides a technical solution: a double-leaf wooden insulated fireproof door, including a door frame 1 and a connecting mechanism for connecting the fireproof door, and two sets of connecting mechanisms are provided. Door bodies 2 are provided on both sides of the inner cavity of the door frame 1. The door bodies 2 are connected to the door frame 1 through the connecting mechanism. Locks are installed on the surface of the door bodies 2. The door bodies 2 include a fireproof frame 21. The inner cavity of the fireproof frame 21 is provided with a heat insulation layer 22 for improving the heat insulation effect. Fireproof and heat-insulating glass magnesium board 23 with fireproof and heat insulation function is glued and fixed on both sides of the fireproof frame 21. A flame-retardant board 3 is glued to the surface of the glass magnesium board 23. A protective structure 4 for protecting the fireproof structure is provided on the surface of the flame-retardant board 3. A decorative panel 5 is connected to the surface of the protective structure 4, and the outer surface of the decorative panel 5 is coated with a fireproof coating. The fireproof frame 21, heat insulation layer 22, glass magnesium board 23, flame-retardant board 3, protective structure 4 and decorative panel 5 are all glued and fixed together with fireproof adhesive.

[0025] In use, the door frame 1 is bolted to the wall. Then, the workers take the door panels 2 on both sides and assemble them with the door frame 1 through the connecting mechanism. After assembly, the double-leaf wooden fire door can be closed. In the event of a fire, the fire source will first come into contact with the fire-retardant coating on the surface of the decorative panel 5. The fire-retardant coating increases the fire resistance and heat insulation effect of the decorative panel 5. Only when the heat penetrates to the decorative panel 5 will it penetrate to the protective structure 4. The protective structure 4 transfers the heat to the flame-retardant board 3. After the flame-retardant board 3 reaches the heat transfer limit, it transfers the heat to the magnesium oxide board 23. At the same time, the internal heat insulation layer 22... In conjunction with isolating the heat on the magnesium oxide board 23, the heat will only penetrate the magnesium oxide board 23, flame retardant board 3, protective structure 4, and decorative board 5 on the back of the fire door in sequence after the heat insulation layer 22 has completely penetrated. When an explosion occurs during a fire, the resulting fragments will only come into contact with the protective structure 4, avoiding damage to the internal structure of the fire door. The above solution improves the heat insulation effect of the double-leaf wooden fire door, prevents damage to the internal structure of the fire door during an explosion, reduces the speed at which heat is transferred to the back of the fire door, and slows down the heat penetration rate.

[0026] The heat insulation layer 22 includes heat insulation board 221, which is provided in two sets. Heat insulation cotton 222 is filled between the two sets of heat insulation board 221. The surface of heat insulation board 221 is bonded and fixed to the surface of magnesium oxide board 23. Through the cooperation of the two sets of heat insulation board 221 and heat insulation cotton 222, double heat insulation is achieved, reducing the heat transfer through the core area of ​​the door body 2 and reducing the speed at which heat penetrates from the front magnesium oxide board 23 to the back magnesium oxide board 23.

[0027] The surface of the heat insulation board 221 is coated with a heat insulation coating, and the sound insulation board 223 is bonded and fixed to the surface of the heat insulation coating. The surface of the sound insulation board 223 is provided with sound-absorbing holes. The heat insulation effect of the heat insulation board 221 is improved by setting the heat insulation coating, and the heat penetration rate is reduced. The sound insulation effect of the fire door is increased by setting the sound insulation board 223, and the sound insulation function and heat insulation function are coordinated.

[0028] The sound-absorbing holes are arranged in several groups in a honeycomb pattern. By utilizing the acoustic buffering properties of the honeycomb structure, the sound insulation contact area is expanded, sound wave energy is absorbed, and the sound insulation effect of the fire door is improved, making it suitable for residential buildings, shopping malls, and other scenarios where noise control is required.

[0029] The protective structure 4 includes a hardwood frame 41, with solid wood boards 42 glued to both sides of the hardwood frame 41. The surface of one set of solid wood boards 42 is glued to the surface of the flame-retardant board 3, and the surface of the other set of solid wood boards 42 is glued to the surface of the decorative board 5. The hardwood frame 41 and the solid wood boards 42 on both sides are glued to form a closed cavity. The hardwood frame 41 undertakes the structural connection and support between the flame-retardant board 3 and the decorative board 5, and improves the structural strength of the middle part of the door 2. The solid wood boards 42 isolate the internal flame-retardant board 3 from external friction and collision, and form physical protection for the internal fireproof and heat-insulating layer 22. The setting of fireproof cotton 43 not only improves the continuity of heat insulation, but also enhances the fireproof redundancy.

[0030] The inner cavity of the hardwood frame 41 is filled with fireproof cotton 43, and the surface of the fireproof cotton 43 is attached to the inner sidewall of the two sets of solid wood boards 42. The fireproof cotton 43 not only improves the continuity of heat insulation, but also enhances the fireproof redundancy, and prevents the gaps from becoming weak points for heat penetration.

[0031] The connecting mechanism includes a connecting seat 6 bolted to the surface of the door body 2 and a mounting seat 7 bolted to the surface of the door frame 1. The bottom end of the connecting seat 6 is integrally formed with a support block 8. The lower surface of the support block 8 is provided with a bearing 9. The surface of the mounting seat 7 is provided with a support groove 10 that matches the bearing 9. The inner cavity of the support groove 10 is engaged with the surface of the support block 8. The support block 8 at the bottom end of the connecting seat 6 is embedded in the support groove 10 of the mounting seat 7. The bearing 9 on the lower surface of the support block 8 enables the smooth rotation of the door body 2 when it is opened and closed. When assembling the door body 2 and the door frame 1, the door body 2 is picked up and the support block 8 on the connecting seat 6 is inserted into the support groove 10, so that the bearing 9 contacts the inner cavity of the support groove 10.

[0032] The outer ring of the bearing 9 is integrally formed with a support plate 11 around its perimeter, and the surface of the support plate 11 is engaged with the inner cavity of the support groove 10. The support plate 11 improves the stability of the bearing 9 in the inner cavity of the support groove 10 and prevents the bearing 9 from tilting or shifting within the support groove 10.

[0033] In practical use: When using, the door frame 1 is installed on the wall with bolts. Then, the staff takes the door bodies 2 on both sides and assembles them with the door frame 1 through the connecting mechanism. Taking the door body 2 drives the support block 8 on the connecting seat 6 to insert into the support groove 10, so that the support plates 11 around the bearing 9 are inserted into the inner cavity of the support groove 10. After insertion, the installation work between the door body 2 and the door frame 1 is completed. After the assembly is completed, the double-leaf wooden fire door can be closed.

[0034] When a fire occurs, the fire source first comes into contact with the fire-retardant coating on the surface of the decorative panel 5. The fire-retardant coating enhances the fire resistance and heat insulation of the decorative panel 5. Only after the heat penetrates the decorative panel 5 will it come into contact with the solid wood board 42. The heat then penetrates the solid wood board 42 on the front of the hardwood frame 41 and is transferred to the fireproof cotton 43. The fireproof cotton 43 prevents the gaps in the hardwood frame 41 from becoming weak points for heat penetration. Finally, the heat penetrates through the solid wood board 42 on the back to the flame-retardant board 3. After the flame-retardant board 3 reaches its heat transfer limit, it transfers heat to the magnesium oxide board 23. At the same time, the two sets of internal heat insulation boards 221 and heat insulation cotton 222 work together to isolate the heat on the magnesium oxide board 23. Only after the heat has completely penetrated will it penetrate the magnesium oxide board 23, flame-retardant board 3, protective structure 4, and decorative panel 5 on the back of the fire door in sequence. The above scheme improves the heat insulation effect of the double-leaf wooden fire door, prevents damage to the internal structure of the fire door in the event of an explosion, reduces the speed at which heat is transferred to the back of the fire door, and slows down the heat penetration rate.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
