Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fireproof door processing, and specifically relates to a layered fireproof structure for wood heat insulation fireproof door. BACKGROUND

[0002] The fireproof door refers to the door that can meet the requirements of fire resistance stability, integrity and heat insulation for a certain time. It is a fireproof partition with certain fire resistance, which is arranged between fireproof compartments, evacuation staircases and vertical shafts. The wood fireproof door refers to the door frame, door leaf skeleton and door leaf panel made of wood or wood products, and the fire resistance limit reaches the requirements of GB50045-95 High-rise Civil Building Design Fireproof Standard.

[0003] The fire retardant treatment of the door frame wood is crucial for the performance of the fireproof door. However, the traditional treatment methods, including spraying and soaking, both cause the wood surface to be wet, affecting the strength of the wood. In addition, the spraying method can cause uneven distribution of the fire retardant, and the soaking method is difficult to ensure that the fire retardant completely penetrates into the wood, both of which can cause poor fire retardant effect, thereby affecting the fireproof performance of the fireproof door. At the same time, when the wood fireproof door is subjected to water impact, its structure is easily damaged or deformed, affecting its fireproof performance.

[0004] In order to solve the above technical problems, a new type of wood fireproof door (CN210195614U) is provided, which includes a door frame and a door leaf. The inner side of the door frame is provided with a convex edge, and the side of the convex edge close to the door leaf is provided with a sealing layer. The surface of the door leaf is provided with an observation glass and a handle, and the door leaf is connected with the door frame through a fireproof hinge. The door leaf includes a fireproof door panel, and the inner side of the fireproof door panel is sequentially provided with a first fire retardant layer, a second fire retardant layer and a heat insulation layer from left to right. The first fire retardant layer includes a fixed frame, and the both sides of the fixed frame are provided with steel wire mesh.

[0005] The above technical solution sets steel wire mesh on both sides of the fixed frame to enhance the structural strength of the wood fireproof door, thereby avoiding the deformation of the structure when it is subjected to water impact. However, the above technical solution only optimizes the structural strength of the wood fireproof door, and the structure of the wood fireproof door still has the problems of reduced wood strength and poor fire retardant effect caused by fire retardant treatment, thereby affecting its fireproof performance.

[0030] The specific embodiments are further described in detail below:

[0031] The reference signs in the drawings of the specification include: wooden frame 1, wooden column 2, strip-shaped storage chamber 3, feeding port 4, round wooden plug 5, partition plate 6, reinforced barrier layer 7, steel mesh 8.

[0032] Embodiment, see Figure 1 and Figure 3 The layered fireproof structure for the wooden fireproof door in the embodiment includes a wooden frame 1, the wooden frame 1 is composed of a plurality of wooden columns 2, a plurality of strip-shaped storage chambers 3 for storing fire-retardant materials are arranged in the wooden columns 2, waterproof cloth is arranged in the strip-shaped storage chambers 3, the waterproof cloth is attached to the inner wall of the strip-shaped storage chambers 3, a plurality of feeding ports 4 are arranged on the wooden columns 2, the positions of the feeding ports 4 correspond to the strip-shaped storage chambers 3 one by one and are communicated with the corresponding strip-shaped storage chambers 3, and a sealing plate is fixedly connected to the wooden frame 1 and covers the two sides of the wooden frame 1 which are not sealed.

[0033] In the embodiment, a plurality of strip-shaped storage chambers 3 for storing fire-retardant materials are arranged in the wooden columns 2, so that the fire-retardant materials are uniformly distributed in the wooden columns 2, the combustibility of the wooden frame 1 is reduced, and the overall fireproof performance of the fireproof door is improved. The waterproof cloth arranged in the strip-shaped storage chambers 3 is mainly made of a high-molecular waterproof and breathable material (PTFE film) and a cloth composite fabric, and has the characteristics of waterproof, heat preservation, moisture permeability, air permeability, insulation, and windproof. The waterproof cloth is attached to the inner wall of the strip-shaped storage chambers 3, so as to isolate the moisture between the fire-retardant materials and the wooden columns 2, avoid the wooden columns 2 from being soaked by the fire-retardant materials, reduce the strength of the wooden columns 2, and avoid the fire-retardant materials from reducing the fireproof performance due to moisture absorption. In addition, the feeding ports 4 are arranged on the wooden columns 2 and are communicated with the strip-shaped storage chambers 3, so that the fire-retardant materials can be directly injected into the strip-shaped storage chambers 3 through the feeding ports 4.

[0034] In addition, the sealing plate covers the two sides of the wooden frame 1 which are not sealed, so as to effectively prevent the fire from spreading through the gaps of the wooden frame 1, improve the overall fireproof performance of the fireproof door, and increase the stability of the wooden fireproof door structure to prevent the wooden fireproof door from being deformed due to external force or water impact.

[0035] See Figure 1 The strip-shaped storage chamber 3 is one, the strip-shaped storage chamber 3 is arranged along the axial direction of the wooden column 2, the longitudinal section of the feeding port 4 is circular, the feeding port 4 faces the internal space of the wooden frame 1, and the feeding port 4 corresponds to and is communicated with the end of the strip-shaped storage chamber 3.

[0036] In this embodiment, a strip-shaped storage chamber 3 is formed inside the wooden column 2. The strip-shaped storage chamber 3 is arranged along the axial direction of the wooden column 2, which allows the flame-retardant material to be evenly distributed inside the wooden column 2. The inlet 4 corresponds to and is connected to the end of the strip-shaped storage chamber 3. During the injection of flame-retardant material, the horizontal plane of the flame-retardant material at the inlet 4 can be observed to confirm whether the flame-retardant material has filled the strip-shaped storage chamber 3. Furthermore, the inlet 4 faces the internal space of the wooden frame 2, maintaining the integrity and aesthetics of the appearance of the wooden frame 2.

[0037] See Figure 2 As shown, there are two strip-shaped storage chambers 3, which are evenly distributed along the axial direction of the wooden column 2. Each feed port 4 is connected to the end of the corresponding strip-shaped storage chamber 3.

[0038] In this embodiment, two strip-shaped storage chambers 3 are opened inside the wooden column 2. The two strip-shaped storage chambers 3 are evenly distributed along the axial direction of the wooden column 2, which can make the flame-retardant material evenly distributed inside the wooden column 2. Furthermore, the wood between the two strip-shaped storage chambers 3 forms an integral structure with the surrounding wood, which can disperse the external force when subjected to external force, reduce local stress, and prevent the wooden column from bending or deforming.

[0039] In this embodiment, the flame-retardant material is a magnesium cementitious material.

[0040] Magnesium-based cementitious materials do not burn at high temperatures and maintain their structural integrity. They do not produce toxic gases, absorb a large amount of heat, and slow down the rise in ambient temperature. Furthermore, their production process does not require high temperatures or pressure. Therefore, magnesium-based cementitious materials are well-suited for use as flame-retardant materials.

[0041] In addition, it also includes a round wooden plug 5, the size of which matches the feed port 4 and is embedded inside the feed port 4, and the outer surface of the round wooden plug 5 is flush with the surface of the wooden column 2.

[0042] In this embodiment, the circular wooden plug 5 can be embedded inside the feed inlet 4 to seal the feed inlet 4 and prevent the magnesium cementitious material from leaking. The outer surface of the circular wooden plug 5 is flush with the surface of the wooden column 2, so that during the subsequent manufacturing process of the fire door, the circular wooden plug 5 will be impacted and generate relative movement between itself and the wooden column 2, thereby damaging the sealing of the feed inlet 4 and causing the magnesium cementitious material to leak.

[0043] See Figure 1 As shown, several partition plates 6 are provided inside the wooden frame 1 along its radial direction. The two sides of the partition plates 6 are fixedly connected to the inner wall of the wooden frame 1. The partition plates 6 divide the internal space of the wooden frame 1 to form several reinforcing barrier layers.

[0044] In this embodiment, the wooden frame 1 is provided with several partition plates 6. The partition plates 6 provide additional support for the wooden frame 1, enhancing the stability of the wooden frame 1 structure. At the same time, the partition plates 6 and the wooden frame 1 form an integral structure, improving the overall rigidity of the wooden frame 1 and preventing it from deforming under external forces. The partition plates 6 divide the internal space of the wooden frame 1 into several reinforcing barrier layers. When subjected to external forces, the reinforcing barrier layers can disperse the external forces, reduce local stress, and thus prevent deformation or damage.

[0045] The reinforced barrier layer includes waste materials and flame retardants. The waste materials are wood chips, and the flame retardants are magnesium cementitious materials.

[0046] In this embodiment, the reinforced barrier layer includes waste materials and flame retardants. The waste materials are wood chips generated during the process of opening the strip-shaped storage chamber 3 in the wooden pillar 2, realizing the reuse of waste materials and saving raw materials. In addition, the mixed use of wood chips and magnesium cementitious materials improves the overall strength of the reinforced barrier layer and prevents it from deforming or breaking when subjected to external forces.

[0047] See Figure 3 As shown, the interior space of the wooden frame 1 is provided with two wire meshes 8, which are located on the upper and lower sides of the partition plate 6 and are fixedly connected to the partition plate 6 with bolts.

[0048] In this embodiment, the internal space of the wooden frame 1 is provided with wire mesh 8 to increase the overall stability of the wooden frame 1 and prevent the wooden frame 1 from deforming or being damaged when subjected to external forces. Secondly, the wire mesh 8 is located on the upper and lower sides of the partition plate 6, which can prevent the partition plate 6 from cracking or deforming during the use of the wooden fire door.

[0049] This embodiment incorporates several strip-shaped storage chambers 3 within the wooden pillar 2 for storing flame-retardant materials. This allows the flame-retardant material to be evenly distributed within the wooden pillar 2, reducing the flammability of the wooden frame 1 and improving the overall fire resistance of the fire door. The strip-shaped storage chambers 3 are lined with waterproof fabric that adheres to the inner wall of the chambers. This isolates the flame-retardant material from the wooden pillar 2, preventing the material from wetting the pillar and reducing its strength. Simultaneously, it prevents the flame-retardant material from absorbing moisture, thus mitigating its fire resistance. This addresses the issues of flame-retardant treatment reducing wood strength and poor flame-retardant effect in wooden fire doors, thereby affecting their fire resistance.

[0050] The above are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
