[0001] The present application relates to the field of fire door design, and in particular to a fireproof wooden door. Background Art

[0002] Fire-rated wooden doors are a type of door structure specially designed to slow the spread of fire and smoke, and play an important role in fire-proof partitions in building design.

[0003] Existing fireproof wooden doors can be made of solid wood or multiple layers of wood, filled with fireproof materials such as rock wool and aluminum silicate. These materials offer excellent thermal, sound, and fireproof properties, effectively preventing the spread of fire in the event of a fire. Furthermore, the door panels are surface-treated with fireproofing treatments, such as spraying flame retardant materials, to enhance their fire resistance.

[0004] However, whether it is a fireproof wooden door made of solid wood or a fireproof wooden door made of multiple layers of wood boards, its overall weight is relatively heavy, which makes the transportation and installation of the fireproof wooden door inconvenient, especially when installing the door structure on high floors, which will cause huge transportation costs and needs to be improved. Utility Model Content

[0005] Based on this, the present application provides a fireproof wooden door structure that can be quickly assembled at the installation site to form an entire fireproof wooden door, which is beneficial to reducing the transportation cost investment of the fireproof wooden door.

[0006] The fireproof wooden door structure provided in this application adopts the following technical solutions:

[0007] A fireproof wooden door structure comprises a fireproof door frame fixedly embedded in a building structure and a fireproof door leaf hinged on one side to the fireproof door frame; wherein the fireproof door leaf comprises a wooden frame board and a plurality of composite panels, an installation space is provided on the top of the wooden frame board, all the composite panels are installed together in the installation space, and each composite panel is abutted in sequence along the height direction; a sealing plate is detachably fixed on the top of the installation space, and the sealing plate abuts against the composite panel located at the top.

[0008] By adopting the above-mentioned technical solution, the fireproof door frame, wooden frame board, plywood and composite panel of the present application can be separately processed and formed and then transported to the construction site separately. Since each component occupies a small volume and is light in weight, the convenience of transportation and handling can be greatly improved, and the transportation cost investment can be reduced. After all the components are transported to the construction site, by installing the composite panels one by one inside the installation space and then fixing the plywood on the top of the installation space, the splicing and assembly of the entire fireproof door leaf can be completed quickly, so that the construction personnel can quickly complete the installation of the fireproof door frame and the fireproof door leaf to form the entire fireproof wooden door structure.

[0009] Optionally, the installation space runs through both sides of the wooden frame in the thickness direction, and the inner wall of the installation space is provided with an inward-concave mortise and tenon; the side of the composite panel is provided with a plug-in tenon block, which is used to cooperate with the inward-concave mortise and tenon.

[0010] By adopting the above technical solution, through the cooperation between the plug-in tenon block and the inner concave tenon groove, the composite panel can be firmly positioned after being installed inside the installation space, reducing the possibility of the composite panel moving horizontally and directly leaving the installation space.

[0011] Optionally, the sealing plate is provided with a first injection hole, and each plug-in tenon block is provided with a second injection hole.

[0017] Optionally, a decorative surface layer is provided on the surface of the composite panel, and decorative edges are provided on the side edges of the composite panel.

[0018] By adopting the above-mentioned technical solution, the setting of decorative edges and corners can enhance the three-dimensional sense of the fire door leaf after each composite panel is installed one by one inside the installation space, and the decorative surface layer set on the surface of the composite panel can make the surface of the fire door leaf have a decorative pattern, which is beneficial to improving the aesthetics of the fire door leaf.

[0019] Optionally, the composite panel includes a first solid wood panel, a honeycomb steel plate, a corrosion-resistant door core and a second solid wood panel that are bonded together in sequence.

[0020] By adopting the above-mentioned technical solution, the first solid wood panel and the second solid wood panel can be used as surface components of the fireproof door leaf, and the wooden surface is more fashionable and simple; the setting of the corrosion-resistant door core can enhance the anti-corrosion effect inside the composite panel and improve its service life, and the setting of the honeycomb steel plate is mainly used to reduce the weight of the composite panel, thereby reducing the overall weight of the fireproof door leaf, so as to facilitate subsequent users to conveniently perform door opening and closing operations.

[0021] Optionally, the honeycomb holes of the honeycomb steel plate are filled with sound insulation cotton.

[0022] By adopting the above technical solution, the provision of sound insulation cotton can enhance the sound insulation effect of the fireproof door leaf, which is conducive to creating a good and comfortable indoor environment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiments of the present application disclose a fireproof wooden door structure.

[0034] Reference Figure 1 A fireproof wooden door structure comprises a fireproof door frame 1 fixedly embedded in a building structure and a fireproof door leaf hinged to the fireproof door frame 1 on one side; the specific structure of the fireproof door frame 1 is conventional in the art and will not be described in detail here. The fireproof door leaf comprises a wooden frame board 2, a sealing board 3 and a plurality of composite panels 4, and also refers to Figure 2 An installation space 21 is provided at the top of the wooden frame 2, and all the composite panels 4 are installed together in the installation space 21, and each of the composite panels 4 is abutted in sequence along the height direction; the sealing plate 3 is detachably fixed to the wooden frame 2, and the sealing plate 3 is located at the top of the installation space 21 and abuts against the composite panel 4 located at the top.

[0035] Reference Figure 3The composite panel 4 includes a first solid wood panel 41, a honeycomb steel plate 42, a corrosion-resistant door core 43, and a second solid wood panel 44, which are sequentially bonded and pressed together along the thickness direction. The first solid wood panel 41 and the second solid wood panel 44 are both made of solid wood and serve as surface components of the fireproof door leaf. The corrosion-resistant door core 43 can be a graphite homogeneous plate, which has excellent corrosion resistance and thus increases the service life of the fireproof door leaf. In addition, the honeycomb steel plate 42 is provided to reduce the weight of the composite panel 4, thereby reducing the overall weight of the resulting fireproof door leaf. At the same time, each honeycomb hole of the honeycomb steel plate 42 is filled with sound insulation cotton 421, which can enhance the sound insulation effect of the resulting fireproof door leaf and contribute to creating a good and comfortable indoor environment.

[0036] During processing, the first and second solid wood panels 41, 44 of this embodiment are each formed with a flame-retardant layer on their surfaces using a pressure-impregnation method, thereby serving as the flame-retardant surface layer of the composite panel 4. Specifically, during processing, the solid wood panels are placed in a high-pressure tank, where a vacuum is first applied to expel the gas within the wood. The vacuum allows the flame retardant to adhere to the surface of the solid wood panels. Pressure is then applied to force the flame retardant into the wood, thereby forming the flame-retardant surface.

[0037] In addition, the opposite sides of the first solid wood panel 41 and the second solid wood panel 44 are respectively provided with decorative surface layers 45, which can serve as decorative patterns on the surface of the composite panel 4 after the panels are bonded to each other; in addition, the side edges of the opposite sides of the first solid wood panel 41 and the second solid wood panel 44 are respectively provided with decorative corners 46, which can enhance the three-dimensional sense of the fire door leaf after each composite panel 4 is installed one by one inside the installation space 21, which is beneficial to improving the aesthetics of the fire door leaf.

[0038] Back to Figure 2 The installation space 21 on the wooden frame 2 for mounting the composite panel 4 extends through both sides of the wooden frame 2 in the thickness direction. The two opposing inner walls of the installation space 21 are each provided with an inwardly recessed tongue and tongue groove 22, which is also connected to the top surface of the wooden frame 2. A door handle member 5 is provided on the side of the wooden frame 2, and an insertion opening 23 is provided on the side of the wooden frame 2, which communicates with the inwardly recessed tongue and tongue groove 22. The door handle member 5 is C-shaped, and its cross-section is the same as that of the insertion opening 23, allowing it to be partially inserted into the insertion opening 23 and into the interior of the inwardly recessed tongue and tongue groove 22. Furthermore, a positioning slot 51 is partially provided on the side of the door handle member 5. After the door handle member 5 enters the insertion opening 23, the positioning slot 51 can be aligned and communicated with the inwardly recessed tongue and tongue groove 22.

[0039] Also refer to Figure 3, the two opposite sides of the composite panel 4 are respectively bonded and fixed with plug-in tenons 48, and the shape of the plug-in tenon blocks 48 is the same as the shape of the inner recessed tenon groove 22. When the composite panel 4 is placed in the installation space 21, the plug-in tenon blocks 48 can enter the inner recessed tenon groove 22 accordingly, and the plug-in tenon blocks 48 and the inner recessed tenon groove 22 can be partially spaced to form a reserved gap; at the same time, the plug-in tenon blocks 48 on a part of the composite panel 4 can partially enter the positioning slot 51, thereby realizing the assembly and fixation of the door handle component 5 and the wooden frame board 2.

[0040] Also refer to Figure 4 The top of the wooden frame 2 is also provided with an additional installation space 24, the width of which is greater than that of the installation space 21. The shape of the closing panel 3 is the same as that of the additional installation space 24, and the closing panel 3 can be fixed to the additional installation space 24 by fasteners such as bolts. In addition, the closing panel 3 is provided with a vertically extending first injection hole 31, and each plug-in tenon 48 is provided with a vertically extending second injection hole 481. When the plug-in tenon 48 enters the inner recessed tenon groove 22, the first injection hole 31 and each second injection hole 481 are directly connected. By pouring resin glue into the second injection holes 481, the resin glue enters the first injection hole 31 and flows upward through the reserved gap. After completely solidifying, a resin glue layer can be formed, thereby improving the connection stability of the wooden frame 2, the closing panel 3, and each composite panel 4, thereby ensuring the normal use of the fireproof door leaf.

[0041] The implementation principle of a fireproof wooden door structure in the embodiment of the present application is as follows:

[0042] After the fireproof door frame 1, wooden frame board 2, sealing board 3 and composite panel 4 of the present application are individually processed and formed, they can be transported separately to the construction site. Since each component occupies a small volume and is light in weight, the convenience of transportation and handling can be greatly improved, and the transportation cost investment can be reduced. After the various components are transported to the construction site, the composite panels 4 are installed one by one inside the installation space 21, and the sealing board 3 is fixed to the installation space 24. Then, resin glue is injected into the first injection hole 31 to form a resin glue layer, which can quickly complete the splicing and assembly of the entire fireproof door leaf, so that construction personnel can quickly complete the installation of the fireproof door frame 1 and the fireproof door leaf.

[0043] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
