Description

Technical Field

[0001] This invention belongs to the field of firewall technology, and more specifically relates to a firewall with a staggered seam structure. Background Technology

[0002] In the field of architectural design, fire resistance of materials has always been of paramount importance. Existing prefabricated fireproof wall panel materials are basically in the form of composite panels, and are often processed into unitized wall panels in the factory and then brought to the construction site for assembly.

[0003] Fireproof wall panel technology is mature in the current field, but the joints between prefabricated wall panels have always been a weak point, frequently experiencing crossfire at the joints, which significantly reduces the overall fire resistance of the fireproof wall panel. Current designs for the joints between prefabricated wall panels typically focus on ease of installation or accurate focusing, often neglecting to address the problem of crossfire. Therefore, overcoming the crossfire phenomenon at the joints between prefabricated wall panels has become a pressing technical problem for those skilled in the art. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a fireproof wall panel with a staggered joint structure to solve the problem of crossfire easily occurring at the joints of prefabricated wall panels in the prior art.

[0005] The objective of this invention is mainly achieved through the following technical solutions: This invention discloses a fireproof panel with a staggered joint structure, which is provided with a keel 10. It is characterized by comprising: a first wall and a second wall, the first wall and the second wall being filled in the keel, the first wall being provided with a first assembly part, the second wall being provided with a second assembly part, and the first assembly part and the second assembly part being assembled and connected by a staggered joint to prevent flames from directly surging from the gaps. Both the first and second walls are filled with multiple layers of insulation material, and the insulation materials are connected in a staggered manner. A cavity is provided in the joint between the first assembly part and the second assembly part, and the cavity is filled with fireproof material to prevent the flame from penetrating.

[0006] Compared with existing technologies, this invention avoids direct flame surge and crossfire at the joints of the fireproof wall panels by staggering the joints of the first and second walls. Through a multi-layered fireproof structure, it effectively prevents crossfire from the gaps in the wall panels during a fire, significantly reducing the risk of fire and the temperature behind the wall panels. Especially near the gaps in the wall panels, the staggered joint design, specific material combination, and layered structure achieve fire isolation at the joints, while improving the overall fire resistance and installation efficiency of the wall panels.

[0007] Furthermore, an anchor is provided at the joint between the first wall and the second wall, and a cover plate is installed on the anchor, which completely covers the joint between the first wall and the second wall.

[0008] Furthermore, fireproof material is filled between the sealing cover plate and the joint between the first wall and the second wall.

[0009] Furthermore, a reinforcing frame is used between the joint of the first wall and the second wall, and the reinforcing frame is fixedly connected to the first wall and the second wall.

[0010] Furthermore, the present invention also includes: a support portion, the support portion being provided with locking bolts, the support portion fixing the first wall and the second wall by means of the locking bolts.

[0011] Furthermore, the present invention also includes: a thermal insulation layer disposed on the outer surface of the first wall and the second wall, the thermal insulation layer being filled with thermal insulation material for insulating the outer layer; The thermal insulation layer is fixed to the reinforced frame.

[0012] Furthermore, the present invention also includes: The base layer and finishing layer are set on the outermost layer of the wall panel to seal gaps; The base layer and decorative surface layer material is made of calcium silicate.

[0014] Furthermore, the internal insulation material of the material layer adopts a modular design, and the gaps between the insulation materials adopt a staggered design.

[0015] Furthermore, the present invention also discloses: a prefabricated enclosure wall, characterized in that it uses the aforementioned fireproof wall panel for the joints of prefabricated wall panels.

[0016] Compared with the prior art, the present invention achieves at least the following beneficial technical effects: By staggering the joints of the first and second walls, direct flame surge and crossfire at the joints of the fireproof wall panels are avoided. Through a multi-layered fireproof structure, crossfire that may occur from the gaps in the wall panels during a fire is effectively prevented, significantly reducing the risk of fire and the temperature behind the wall panels. Especially near the gaps in the wall panels, the staggered joint design, specific material combinations, and layered construction achieve fire isolation at the joints, while improving the overall fire resistance and installation efficiency of the wall panels.

[0027] A specific embodiment of the present invention discloses a fireproof wall panel with a staggered joint structure, provided with a keel 10. The keel 10 serves as the main structure of the wall panel and also as the filling position for subsequent structural layers. In the present invention, the keel 10 adopts a grid-shaped galvanized steel frame as the main structure of the fireproof wall panel. The use of galvanized steel can effectively utilize the high toughness, large span load-bearing capacity of steel, and the characteristics of cold bending, welding, and assembly, resulting in high construction efficiency. Moreover, it meets the basic requirements of fireproof materials: it is a non-combustible material, does not burn, does not release toxic fumes, and will not aggravate the fire or produce toxic gases in a fire.

[0028] Specifically, this embodiment includes: a first wall 1 and a second wall 2, the first wall 1 and the second wall 2 are filled in the keel 10, the first wall 1 is provided with a first assembly part 101, the second wall 2 is provided with a second assembly part 201, and the first assembly part 101 and the second assembly part 201 are assembled and connected by staggered joints to prevent flames from directly surging out from the gaps. In a preferred embodiment of the present invention, both the first wall 1 and the second wall 2 are provided with two material layers, namely a first material layer and a second material layer. The first material layer of the first wall 1 and the first material layer of the second wall 2 abut against each other, and the second material layer of the first wall 1 and the second material layer of the second wall 2 abut against each other. The first assembly part 101 is the overlapping part of the first material layer of the first wall 1 relative to the second material layer of the first wall 1; the second assembly part 201 is the overlapping part of the second material layer of the second wall 2 relative to the first material layer of the second wall 2. The first assembly part 101 and the second assembly part 201 overlap, and the connection between the first wall 1 and the second wall 2 is realized through the internal reinforcing frame 5. With this arrangement, the gap formed by the abutment and connection of the first wall 1 and the second wall 2 can be staggered, so as to prevent flames from directly entering through the gap connecting the first wall 1 and the second wall 2 in the event of a fire.

[0029] It should be noted that the terms "first" and "second" in this invention are merely classifications based on spatial location or order, to clarify the relative relationships between different walls or different material layers.

[0030] It is not difficult to understand that the first assembly part 101 and the second assembly part 201 in the above embodiment are one of many possible staggered implementations. In some other embodiments, they can also be configured as follows: both the first wall 1 and the second wall 2 are provided with three material layers, namely a first material layer, a second material layer, and a third material layer, with the second material layer located between the first material layer and the third material layer; the first material layer of the first wall 1 and the first material layer of the second wall 2 abut against each other, the second material layer of the first wall 1 and the second material layer of the second wall 2 abut against each other, and the third material layer of the first wall 1 and the third material layer of the second wall 2 abut against each other; the thicknesses of the first material layer, the second material layer, and the third material layer are equal. The components are arranged in an orderly manner. The first assembly part 101 is the overlapping part of the second material layer of the first wall 1 relative to the first material layer and the third material layer of the first wall 1. The second assembly part 201 is the overlapping part of the first material layer and the third material layer of the second wall 2 relative to the second material layer of the second wall 2. The first assembly part 101 and the second assembly part 201 overlap and are connected to the first wall 1 and the second wall 2 by the internal reinforcing frame 5. In this embodiment, the first assembly part 101 and the second assembly part 201 are set as grooves to further realize the staggered gaps and prevent flames from directly entering from the gap connecting the first wall 1 and the second wall 2 when a fire occurs.

[0031] It is easy to understand that in this preferred embodiment, the protruding assembly parts are all regular rectangles. In some other embodiments, they may also be in other forms. In some other embodiments, the first assembly part 101 may be a protruding semi-cylinder, or it may be a protruding triangular pyramid or other irregular forms. In this case, the second assembly part 201 may be a recess that matches the shape of the first assembly part 101, so as to meet the staggered joint feature requirement when the first wall 1 and the second wall 2 are assembled in a variety of ways. In addition to the above methods, the staggered joint can also be set in many other forms, such as plug-in or snap-fit, which will not be described in detail here.

[0032] Specifically, in a preferred embodiment of the present invention, both the first wall 1 and the second wall 2 are filled with multiple layers of thermal insulation material, and the thermal insulation materials are connected in a staggered manner. As described above, in the preferred embodiment of the present invention, the first wall 1 adopts a double-layer material structure. In some other embodiments, a three-layer or more material layer structure may also be adopted. The wall is filled with a high-temperature resistant material, and materials with low heat transfer coefficient, low thermal conductivity, high temperature resistance, and lightweight should be preferred, such as one or more of the following thermal insulation materials: aluminum silicate wool, rock wool, and glass wool, to further reduce heat transfer during a fire. In this embodiment, the wall is filled with rock wool.

[0033] It should be noted that the material layers in the wall panels are filled using modular materials, which improves processing efficiency and the overall modularity of the wall structure, facilitating initial processing and installation as well as subsequent wall maintenance.

[0034] Furthermore, the gaps between the material modules of the first material layer and the gaps between the material modules of the second material layer are also designed with staggered joints. This is to prevent flames from shooting straight out from the gaps in the material layers when the fire is large and the outer finish of the material layers of the first wall 1 and the second wall 2 is damaged. Specifically, when the outer surface of the first material layer is facing the direction of the fire, the flames shooting straight out from the gaps between the material modules of the first material layer will be blocked by the material modules of the second material layer, instead of shooting straight out from the gaps between the material modules of the second material layer, thus further ensuring the reliability of the fire wall panel. The same principle applies when the outer surface of the second material layer is facing the direction of the fire.

[0035] In a preferred embodiment of the present invention, a cavity 3 is provided in the assembly connection gap between the first assembly part 101 and the second assembly part 201, and the cavity 3 is filled with fireproof material to prevent the penetration of flame.

[0036] Specifically, the cavity 3 is formed by the enclosure between the first assembly part 101 and the second assembly part 201 when the first assembly part 101 of the first wall 1 is installed and abuts against the first material layer of the second wall 2, and the second assembly part 201 of the second wall 2 is installed and abuts against the second material layer of the first wall 1.

[0037] In a preferred embodiment of the present invention, both the first assembly part 101 and the second assembly part 201 are regular cuboids. Therefore, the cavity 3 enclosed by the first assembly part 101 and the second assembly part 201 is also a regular geometric space. In some other embodiments, as described above, if the first assembly part 101 is a protruding semi-cylinder or a protruding triangular pyramid or other irregular form, and the second assembly part 201 is a recessed groove, the cavity 3 enclosed by the two should also be changed accordingly.

[0038] Specifically, the cavity 3 is enclosed by a reinforcing frame 5, which in this application uses galvanized steel as the frame material.

[0039] In a preferred embodiment of the present invention, the joint between the first wall 1 and the second wall 2 is composed of the gap between the first material layers of the two walls, the cavity 3 enclosed by the first assembly part 101 and the second assembly part 201, and the gap between the second material layers of the first wall 1 and the second wall 2. Depending on the specific design of the first assembly part 101 and the second assembly part 201, it can form a variety of irregular gap structures to prevent flames from rushing out from the gaps in the wall panel joints and causing harm to facilities or personnel behind the wall.

[0040] However, even in extremely severe fire conditions, there is still a risk that flames may enter through the gaps in the wall panel joints and pass through the irregular cavity 3, potentially causing damage behind the wall panel joints. Therefore, in order to solve the above problem, in a preferred embodiment of the present invention, sufficient fireproof material is filled into the cavity 3. The selected fireproof material should have a low heat transfer coefficient, low thermal conductivity, high temperature resistance, and lightweight, that is, good fire resistance and strong plasticity, such as one or more of the thermal insulation materials such as aluminum silicate wool, rock wool, and glass wool, so as to ensure the convenience of installation and replaceability while ensuring fire resistance. In this application, aluminum silicate wool is used.

[0041] In a preferred embodiment of the present invention, a cover plate 4 is provided at the joint between the first wall 1 and the second wall 2, and the cover plate 4 completely covers the joint between the first wall 1 and the second wall 2. Anchors are provided on the cover plate 4, and the cover plate 4 is fixed to the first wall 1 and the second wall 2 via the anchors.

[0042] Specifically, in a preferred embodiment of the present invention, in order to prevent flames from entering the joint between the first wall panel and the second wall panel, a cover plate 4 is provided at the joint between the first wall panel and the second wall panel. In this application, galvanized steel, a lightweight metal material with good fire resistance and high temperature resistance, is selected. In some other embodiments, other fire-resistant materials such as calcium silicate may also be selected.

[0043] By installing a cover plate 4 at the joint between the first wall 1 and the second wall 2, the connection between the first wall 1 and the second wall 2 is made tighter, serving as the first line of fire protection to prevent flames from entering the gap between the first wall 1 and the second wall 2 as much as possible.

[0044] Furthermore, fireproof and heat-insulating material is filled between the cover plate 4 and the first wall 1 and the second wall 2 to further prevent flames from entering the joint gap between the first wall 1 and the second wall 2. The selected fireproof material should have a low heat transfer coefficient, low thermal conductivity, high temperature resistance, and lightweight, that is, a material with good fire resistance and strong plasticity, such as one or more heat insulation materials such as aluminum silicate wool, rock wool, and glass wool, so as to ensure the convenience of installation and replaceability while ensuring fire resistance. This application uses aluminum silicate wool.

[0045] In a preferred embodiment of the present invention, a reinforcing frame 5 is used between the joint of the first wall 1 and the second wall 2. The reinforcing frame 5 is fixedly connected to the first wall 1 and the second wall 2, thereby ensuring the stable connection between the first wall 1, the second wall 2 and other parts of the wall panel. As an internal connecting component of the firewall, it must have sufficient rigidity and fire resistance. At the same time, in order to ensure the ease and efficiency of the installation and disassembly of the wall itself, a relatively lightweight metal material is required. In this application, galvanized steel is selected as the metal keel 10. Alternatively, heat-resistant and lightweight metal materials such as aluminum-based alloys or titanium-based alloys can also be used.

[0046] In a preferred embodiment of the present invention, since both the first assembly part 101 and the second assembly part 201 are regular cuboids, and the cavity 3 enclosed by the first assembly part 101 and the second assembly part 201 is also a regular geometric space, the reinforcing frame 5 is a regular cuboid metal frame made of galvanized steel. In some other embodiments, as described above, if the first assembly part 101 is a protruding semi-cylinder or a protruding triangular pyramid or other irregular form, and the second assembly part 201 is a recessed groove, the cavity 3 enclosed by the two should also be changed accordingly, and the geometry of the internal reinforcing frame 5 should also be adjusted accordingly.

[0047] It should be noted that, in some embodiments of the present invention, if no other material layers are added to the outside of the first wall 1 and the second wall 2, the reinforcing frame 5 should extend to the outer surface of the first wall 1 and the second wall 2 where no other material layers are added, as a base layer and a fire-resistant first layer, and be connected to the keel 10.

[0048] In a preferred embodiment of the present invention, the wall panel further includes a support portion 11. The aforementioned reinforcing frame 5 is an important frame for ensuring stable connection between the first wall 1, the second wall 2, and other parts of the wall panel. The support portion 11 is the main structure for ensuring the connection within the wall panel and supporting the wall panel.

[0049] Given the importance of the support part 11 as the main structure supporting the wall panel, it should be designed in the safest position of the wall panel to avoid damage and failure of the support part 11 in the event of a fire, which would cause the firewall to collapse and fail to perform its due function.

[0050] Specifically, the arrangement of the support part 11 varies depending on whether the wall panel is one-way or two-way fireproof. In the one-way fireproof version, the support part 11 is located at the joint between the first wall 1 and the second wall 2 in the direction of non-expected fire, ensuring a tight connection between the first wall 1 and the second wall 2 while supporting the entire fireproof wall panel. In the two-way fireproof version, the support part 11 is located in the cavity 3 formed by the first assembly part 101 of the first wall 1 and the second assembly part 201 of the second wall 2, and the wall and the main structure of the support part 11 are secured by locking bolts 8 to keep them as far away from the expected fire direction as possible.

[0051] The support part 11 is provided with a locking bolt 8, and the support part 11 is fixed to the first wall 1 and the second wall 2 by the locking bolt 8.

[0052] In a preferred embodiment of the present invention, the support part 11 is a regular cuboid frame. Depending on specific design requirements and application scenarios, it can also be set as a solid cuboid, cylinder, or other irregular frame and solid body, as long as it can maintain a tight connection between the first wall 1 and the second wall 2 while supporting the entire fireproof panel. The specific design of the support part 11 is described in detail in the following specific embodiments.

[0053] In a preferred embodiment of the present invention, the wall panel further includes: a thermal insulation layer 6, which is disposed on the outer surface of the first wall 1 and the second wall 2 away from the expected fire-affected direction. The thermal insulation layer 6 is filled with thermal insulation material. In addition to sealing and preventing the penetration of flames at the gaps, the thermal insulation layer 6 is more importantly used to reinforce the heat on the frame 5 so that it can directly contact the base layer and decorative surface layer 7 behind it. The selected fireproof material should have a low heat transfer coefficient, low thermal conductivity, high temperature resistance, and lightweight, that is, a material with good fire resistance and strong plasticity, such as one or more of thermal insulation materials such as aluminum silicate wool, rock wool, and glass wool, so as to ensure the convenience of installation and replaceability while ensuring fire resistance. This application uses aluminum silicate wool.

[0054] The thermal insulation layer 6 is fixed to the keel 10.

[0055] In a preferred embodiment of the present invention, the wall panel further includes: a base layer and decorative layer 7, which is disposed on the outermost layer of the wall panel to completely seal the gaps and prevent flames from directly burning out of the gaps in the wall panel. At the same time, as a base layer and decorative layer, it plays a role in decorating and reinforcing the durability of the wall panel. The base layer and decorative surface layer 7 is made of calcium silicate.

[0056] The following details two preferred embodiments of the present invention.

[0057] Example 1 provides a one-way staggered firewall version.

[0058] This embodiment is mainly used for unidirectional fire protection; therefore, as described above, the support 11 is disposed on the outer surface of the base layer and decorative layer 7, away from the intended fire-exposed direction. The structure from the intended fire-exposed surface to the unexposed surface is as follows: The cover plate 4 is made of lightweight, high-temperature resistant galvanized steel plate. It is installed on the keel 10, the first wall 1 and the second wall 2 by anchors, so that the connection between the first wall 1 and the second wall 2 is tighter, while serving as the first line of fire protection to prevent flames from entering the gap between the first wall 1 and the second wall 2 as much as possible.

[0059] The thermal insulation and fireproofing material filled between the cover plate 4 and the wall is aluminum silicate cotton in this embodiment. The aluminum silicate cotton is used to seal the front section of the wall panel joint. In this embodiment, the aluminum silicate cotton adopts an auxiliary cover strip design to seal the gap between the cover strip and the wall panel, further preventing the penetration of flames.

[0060] The keel 10, which serves as the main connecting and supporting structure of the wall, is fixedly connected to the reinforcing frame 5, and the material is a galvanized steel frame.

[0061] In this embodiment, the first wall 1 and the second wall 2 are made of rock wool. Both the first wall 1 and the second wall 2 are divided into a first material layer and a second material layer. The internal materials of each material layer adopt a modular design. The gaps between the material modules in the first material layer and the gaps between the material modules in the second material layer also adopt a staggered design. This prevents flames from directly escaping from the gaps in the material layers when the fire is large and the outer finish of the material layers of the first wall 1 and the second wall 2 is damaged. The first material layer of the first wall 1 and the first material layer of the second wall 2 abut against each other, and the second material layer of the first wall 1 and the second material layer of the second wall 2 abut against each other. The first assembly part 101 is the first wall... The first material layer of body 1 overlaps with the second material layer of the first wall body 1; the second assembly part 201 is the overlap of the second material layer of the second wall body 2 with respect to the first material layer of the second wall body 2. The first assembly part 101 and the second assembly part 201 overlap and are connected to the first wall body 1 and the second wall body 2 through the internal reinforcing frame 5. The first assembly part 101 and the second assembly part 201 enclose and form a cuboid cavity 3. The staggered design is achieved through the first assembly part 101 and the second assembly part 201 to avoid the direct flow of flames; and by filling the cavity 3 with aluminum silicate cotton, it is possible to prevent flames from gushing out from irregular gaps in severe fire conditions.

[0062] The keel 10, which serves as the main connecting and supporting structure of the wall, is fixedly connected to the reinforcing frame 5, and the material is a galvanized steel frame.

[0063] The insulation layer 6, made of aluminum silicate cotton, is installed on the outer surface of the unintended fire-exposed surfaces of the first wall 1 and the second wall 2. It is fixed to the metal keel 10 and the first wall 1 and the second wall 2 by locking bolts 8. The aluminum silicate cotton is used for insulation at the rear of the wall panel. In addition to sealing the gap between the cover plate 4 and the wall panel to prevent the penetration of flames, it is more important to prevent the heat on the metal keel 10 from directly contacting the underlying base layer and decorative layer 7.

[0064] The base layer and decorative surface layer 7 is made of calcium silicate. The base layer and decorative surface layer 7 is set on the outer surface of the insulation layer 6. It serves as the last line of fire protection to prevent flames from burning directly through the gaps in the wall panels. It is fixed to the metal keel 10 and the reinforcing frame 5 by locking bolts 8, and also plays a key role in support, fixation and force transmission.

[0065] The support part 11, in this embodiment, is located on the outer surface of the base layer / decorative layer 7, i.e., the surface away from the intended fire-exposed surface. The support part 11 is a hollow galvanized steel frame, installed at the joint between the first wall 1 and the second wall 2. A metal bracket is provided on the outer surface of the base layer / decorative layer 7 relative to the joint between the first wall 1 and the second wall 2. In this embodiment, the support part 11 is fixed to the metal bracket and the wall by locking bolts 8. There are two sets of locking bolts 8: one set connects to the wall and the metal keel 10 within the wall to fix the support part 11 to the wall panel, allowing the support part 11 to perform its supporting function; the other set is used for fixing the support part 11 and the metal bracket, strengthening the connection between the metal bracket and the support part 11 while reducing the impact of possible vibrations.

[0066] Example 2 provides a two-way staggered firewall version.

[0067] This embodiment is mainly used for two-way fire protection, that is, both sides need to be equipped with corresponding fireproof structures. Therefore, as mentioned above, the support part 11 is set in the cavity 3 formed by the first assembly part 101 of the first wall 1 and the second assembly part 201 of the second wall 2. The wall and the main structure of the support part 11 are locked by the locking bolts 8 to keep them as far away from the expected fire direction as possible.

[0068] In this embodiment, the structures from the intended fire-exposed surface to the unfired surface are as follows: The base layer and decorative surface layer 7 is made of calcium silicate. The base layer and decorative surface layer 7 is set on the outer surface of the insulation layer 6. It serves as the last line of fire protection to prevent flames from burning directly through the gaps in the wall panels. It is fixed to the metal keel 10 and the reinforcing frame 5 by locking bolts 8, and also plays a key role in support, fixation and force transmission.

[0069] The insulation layer 6, made of aluminum silicate cotton, is installed on the outer surface of the unintended fire-exposed surfaces of the first wall 1 and the second wall 2. It is fixed to the metal keel 10 and the first wall 1 and the second wall 2 by locking bolts 8. The aluminum silicate cotton is used for insulation at the rear of the wall panel. In addition to sealing the gap between the cover plate 4 and the wall panel to prevent the penetration of flames, it is more important to prevent the heat on the metal keel 10 from directly contacting the underlying base layer and decorative layer 7.

[0070] The cover plate 4 is made of lightweight, high-temperature resistant galvanized steel sheet. It is installed on the keel 10, the first wall 1, and the second wall 2 via anchors, making the connection between the first wall 1 and the second wall 2 tighter and serving as the first line of fire protection to prevent flames from entering the gap between the first wall 1 and the second wall 2 as much as possible. Since the outer side is provided with a base layer / decorative layer 7 and a thermal insulation layer 6, the wall is designed with a recess at the location of the cover plate 4 to facilitate the installation of the cover plate 4 and the external structural layer, prevent the wall from protruding when viewed from the outside, which would affect the aesthetics, and facilitate the assembly, maintenance, and replacement of the wall.

[0071] The thermal insulation and fireproofing material filled between the cover plate 4 and the wall is aluminum silicate cotton in this embodiment. The aluminum silicate cotton is used to seal the front section of the wall panel joint. In this embodiment, the aluminum silicate cotton adopts an auxiliary cover strip design to seal the gap between the cover strip and the wall panel, further preventing the penetration of flames.

[0072] The keel 10, which serves as the main connecting and supporting structure of the wall, is fixedly connected to the reinforcing frame 5, and the material is a galvanized steel frame.

[0073] In this embodiment, the first wall 1 and the second wall 2 are made of rock wool. Both the first wall 1 and the second wall 2 are divided into a first material layer and a second material layer. The internal materials of each material layer adopt a modular design. The gaps between the material modules in the first material layer and the gaps between the material modules in the second material layer also adopt a staggered design. This prevents flames from directly escaping from the gaps in the material layers when the fire is large and the outer finish of the material layers of the first wall 1 and the second wall 2 is damaged. The first material layer of the first wall 1 and the first material layer of the second wall 2 abut against each other, and the second material layer of the first wall 1 and the second material layer of the second wall 2 abut against each other. The first assembly part 101 is the first wall... The first material layer of body 1 overlaps with the second material layer of the first wall body 1; the second assembly part 201 is the overlap of the second material layer of the second wall body 2 with respect to the first material layer of the second wall body 2. The first assembly part 101 and the second assembly part 201 overlap and are connected to the first wall body 1 and the second wall body 2 through the internal reinforcing frame 5. The first assembly part 101 and the second assembly part 201 enclose and form a cuboid cavity 3. The staggered design is achieved through the first assembly part 101 and the second assembly part 201 to avoid the direct flow of flames; and by filling the cavity 3 with aluminum silicate cotton, it is possible to prevent flames from gushing out from irregular gaps in severe fire conditions.

[0074] The support 11 is disposed within the cavity 3 formed by the first wall 1 and the second wall 2. It is mounted on the ground or other intended installation location via mounting feet at the bottom of the support 11, and is fixedly connected to the wall via locking bolts 8 installed on the added frame. As described above, this serves to stabilize the wall panel installed in the external environment while making the connection between the first wall 1 and the second wall 2 tighter.

[0075] Keel 10, same as above.

[0076] The thermal insulation and fireproofing material filled between the cover plate 4 and the wall is the same as described above.

[0077] Cover plate 4 is the same as described above.

[0078] Insulation layer 6 is the same as described above.

[0079] The base layer and decorative surface layer 7 are consistent with the above.

[0080] By setting a symmetrical structure, the two-way fireproof wall panel can maximize its fireproof effect regardless of which side is exposed to fire.

[0081] The present invention also discloses: a prefabricated enclosure wall, characterized in that it uses the aforementioned fireproof wall panels, and the enclosure wall is composed of a plurality of fireproof wall panels, which can be used for fireproof rooms and fireproof chambers.

[0082] This invention effectively prevents crossfire from the gaps in the wall panels during a fire through a multi-layered fireproof structure, significantly reducing the risk of fire and the temperature behind the wall panels. In particular, near the gaps in the wall panels, the staggered joint design, specific material combination, and layered structure achieve fire isolation at the joints, while improving the overall fire resistance and installation efficiency of the wall panels.

[0083] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
