[0031] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0032] "Top surface", "bottom", and "bottom surface" are referenced to the normal use state, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0033] First Embodiment

[0034] As Figures 1-7 shown, the curtain wall composite fireproof board of the first embodiment of the present utility model includes:

[0035] A fireproof composite board 1, the fireproof composite board 1 includes a fireproof frame 11, the fireproof frame 11 has fireproof through holes that are densely distributed and extend along its own thickness direction, and heat preservation rock wool 12 is filled in the fireproof through holes. The fireproof frame 11 includes a closed-loop outer frame 111 and a support grid 112 fixed to the inner side of the outer frame 111;

[0036] Two wall panels 2, the two wall panels 2 are respectively an outer wall panel 21 laminated on the side adjacent to the outdoor side of the fireproof composite board 1 and an inner wall panel 22 laminated on the side adjacent to the indoor side of the fireproof composite board 1;

[0037] A fastening assembly 3, the fastening assembly 3 is distributed along the circumference of the fireproof composite board 1. The fastening assembly 3 includes a bolt 31 and a nut 32 that are threadedly connected. The rod portion of the bolt 31 sequentially passes through the outer wall panel 21, the fireproof composite board 1, and the inner wall panel 22, and the nut 32 abuts against the side of the inner wall panel 22 facing away from the fireproof composite board 1.

[0038] In this curtain wall composite fireproof board, the materials of the support grid 112 and the two wall panels 2 are both aluminum alloy, that is, the support grid 112 is an aluminum alloy grid, and the wall panel 2 is an aluminum alloy plate, so as to ensure the overall structural strength of the curtain wall composite fireproof board. Specifically, the aluminum alloy material has a high strength-to-weight ratio, which ensures that the support grid 112 and the two wall panels 2 maintain a light weight while providing sufficient structural strength, which is beneficial to reducing the overall load of the building; and after a series of treatments such as anodic oxidation and electrophoretic coating on the aluminum alloy surface, a dense oxide film can be formed, effectively resisting the erosion of the atmosphere, water, and chemical substances, and extending the service life of the curtain wall.

[0039] In order to form the support grid 112, in this embodiment, the support grid 112 is formed by connecting a plurality of long strip-shaped aluminum alloy support plates 1121. Specifically, the sizes of the support plates 1121 are the same. An embedding groove 1122 extending along the length direction of the support plate 1121 is arranged on the same side of the support plate 1121. The depth of the embedding groove 1122 is half of the width of the support plate 1121, and the width of the groove is the width of the support plate 1121. After adopting the above structure, after the embedding grooves 1122 of the respective support plates 1121 are butted against each other, the support grid 112 in a net structure can be formed. After the support grid 112 is installed in the outer frame 111, the fireproof frame 11 can be formed. Fireproof through holes are densely arranged in a rectangular array on the fireproof frame 11, and the heat-insulating rock wool 12 can be filled in the fireproof through holes.

[0040] The heat-insulating rock wool 12 is mainly used for the fire prevention of the fireproof composite board 1, and it plays an important fire prevention role in the curtain wall. This is mainly because the heat-insulating rock wool 12 uses basalt as the main raw material, has an extremely high melting point (usually above 1150 °C), can maintain stability for a long time in a fire, is not easy to burn or soften, and has a fire resistance limit of up to two hours, which can effectively prevent the spread of fire in the building and buy precious time for personnel evacuation and fire fighting and rescue. Moreover, the heat-insulating rock wool 12 also has excellent heat insulation and heat preservation performance, can effectively reduce the heat transfer between the building and the external environment, and improve the energy utilization efficiency of the building. In addition, the porous structure inside the heat-insulating rock wool 12 makes it have good sound insulation performance, so it can reduce the influence of external noise on the interior of the building and provide a quieter and more comfortable environment.

[0041] To sum up, for the curtain wall composite fireproof board of the present utility model, the support grid 112 made of aluminum alloy is used as the main structural support, and the wall panels 2 on both sides are used as auxiliary structural supports. Aluminum alloy itself has certain fire resistance, and the heat-insulating rock wool 12 filled inside is an excellent fireproof and heat-insulating material, which can effectively organize the spread of fire and improve the heat insulation and heat preservation effect of the curtain wall, contributing to energy conservation and emission reduction. The net structure of the support grid 112 can form a stable support system, thus ensuring the excellent fire resistance and structural strength of the curtain wall composite fireproof board.

[0042] A further improvement is that the fireproof composite board 1 further includes heat-insulating plates 13 respectively arranged on the support grid 112 and located inside the outer frame 111.

[0043] By arranging the heat-insulating plates 13 on both sides of the support grid 112, the circumferential outer edge of the heat-insulating plate 13 is hermetically attached to the circumferential inner wall of the outer frame 111, which can block the heat transfer between the indoor side and the outdoor side, improve the heat preservation performance, achieve energy conservation and emission reduction, and can reduce the heating rate of the fireproof composite board 1 in case of a fire.

[0044] A further improvement is that the heat-insulating plate 13 is an XPS board; the outer frame 111 is an XPS frame.

[0045] XPS, namely extruded polystyrene, is known for its high compressive strength, with a compressive strength of 150 - 500 Kpa or even higher. This high-strength characteristic enables the heat insulation board 13 and the outer frame 111 to have excellent structural strength, be able to withstand large loads, and not be easily deformed or damaged during long-term use. Moreover, the tensile strength of the XPS board and the XPS frame is also relatively high, usually between 150 kPa - 700 Kpa, ensuring good integrity when the XPS board and the XPS frame are subjected to external forces and not being easily broken or damaged. In addition, the XPS board and the XPS frame have a completely closed-cell foaming chemical structure, similar to a honeycomb physical structure. This structure makes the heat insulation board 13 and the outer frame 111 lightweight and highly elastic, and the closed-cell rate reaches over 99%, avoiding heat dissipation due to air flow, thus ensuring the durability and stability of the heat preservation performance.

[0046] A further improvement is that a positioning slot 131 is provided on the surface of the heat insulation board 13 adjacent to the support grid 112, and the support grid 112 is inserted and matched with the positioning slot 131.

[0047] As Figure 5 shown, the positioning slot 131 is a mesh slot. When assembling the fireproof composite board 1, by sleeving the positioning slot 131 on the side of the support grid 112, on the one hand, it can achieve the precise docking of the heat insulation board 13 and the support grid 112, ensuring that the circumferential outer edge of the heat insulation board 13 is hermetically fitted with the circumferential inner wall of the outer frame 111. On the other hand, when the two heat insulation boards 13 approach each other, after the positioning slot 131 on the heat insulation board 13 is sleeved on the end of the support grid 112, the two heat insulation boards 13 can squeeze the thermal insulation rock wool 12 inside the fireproof through-hole of the fireproof frame 11, ensuring its filling inside the fireproof through-hole.

[0048] A further improvement is that a positioning blind hole is formed by the surface of the heat insulation board 13 facing away from the support grid 112 and the circumferential inner wall of the outer frame 111. An outer wall positioning boss 211 and an inner wall positioning boss 221 are respectively provided on the outer wall panel 21 and the inner wall panel. The outer wall positioning boss 211 and the inner wall positioning boss 221 are respectively inserted and matched with the positioning blind holes on both sides of the fireproof composite board 1.

[0049] After adopting the above design, a positioning blind hole is formed by the surface of the heat insulation board 13 facing away from the support grid 112 and the circumferential inner wall at the end of the outer frame 111, facilitating the precise insertion of the outer wall positioning boss 211 on the outer wall panel 21 and the inner wall positioning boss 221 on the inner wall panel 22, thus ensuring the precise docking of the two wall panels 2 and the fireproof composite board 1 and improving the quality of the curtain wall composite board.

[0050] A further improvement is that it further includes a decorative panel 5, which is stacked and connected to the side of the exterior wall panel 21 facing away from the fireproof composite board 1 and covers the fastening assembly 3; a stepped hole 212 is provided on the exterior wall panel 21, and the stepped hole 212 is used to accommodate the cap portion of the bolt 31.

[0051] In this embodiment, holes can be pre-drilled on the exterior wall panel 21 to form a plurality of stepped holes 212. The stepped holes 212 include a circular hole portion and a hexagonal prism portion with the same axis. The inner diameter of the circular hole portion is the same as the outer diameter of the rod portion of the bolt 31 for the rod portion of the bolt 31 to pass through. The hexagonal prism portion is adapted to the cap portion of the bolt 31 and can accommodate the cap portion of the bolt 31. Then, the decorative panel 5 is fixed to the exterior wall panel 21. The decorative panel 5 is preferably made of the same material as the exterior wall panel 21, i.e., aluminum alloy, and the two are fixedly connected by resistance welding. Then, various materials are sprayed on the decorative panel 5 to enhance its decorative performance, thereby enhancing the weather resistance, corrosion resistance, abrasion resistance, etc. of the decorative panel 5. The sprayed materials include but are not limited to acrylic paint, polyurethane paint, fluorocarbon paint, epoxy paint, polyvinylidene fluoride resin, etc. In this way, finally, the decorative panel 5 can cover and block the bolt 31, avoiding affecting the overall appearance of the curtain wall composite fireproof board.

[0052] In summary, for the curtain wall composite fireproof board of this embodiment, the support grid 112 made of aluminum alloy is used as the skeleton, which cooperates with the outer frame 111 to form the fireproof frame 11. The fireproof through holes in the fireproof frame 11 are filled with thermal insulation rock wool 12, and then heat insulation boards made of XPS are connected to both sides. This structure enables the composite board to have high rigidity and anti-deformation ability while maintaining light weight. The support grid 112 itself has high strength and stability, and can effectively support and disperse the load. The heat insulation board 13 and the outer frame 111 also have certain compressive and tensile strengths. The thermal insulation rock wool 12 filled in the fireproof through holes, as an inorganic thermal insulation material, has good fireproof performance and is not easy to burn and can withstand high temperatures. Therefore, this composite board can maintain good structural stability in a fire, is not easy to burn and can prevent the spread of fire, and has excellent fireproof performance and structural stability. And through the fastening assembly 3 composed of bolts 31 and nuts 32, it is convenient for the quick splicing between the fireproof composite board 1 and the two wall panels 2, which is beneficial to improving the construction efficiency.

[0053] Second Embodiment

[0054] As Figure 8 and Figure 9 shown, the curtain wall composite fireproof board of the second embodiment of the present utility model, based on the first embodiment, is different in that fireproof sealant 4 surrounding the periphery of the fireproof composite board 1 is provided between the two wall panels 2 and the fireproof composite board 1.

[0055] Specifically, on one side of the circumferential outer edge of the two wall panels 2 adjacent to the fireproof composite board 1, a first notch is provided. At both ends of the circumferential outer edge of the fireproof composite board 1, second notches are provided. The first notch and the second notch are combined to form a glue groove for the fireproof sealant 4 to cure and form. The glue groove is in a closed-loop shape.

[0056] After the two wall panels 2 are tightly connected to the two sides of the fireproof composite board 1 through bolts 31 and nuts 32, the first notch on the circumferential outer edge of the wall panel 2 is aligned and communicated with the second notch on the circumferential outer edge of the outer frame 111, and a glue groove in the shape of a rectangular frame is formed. By injecting the fireproof sealant 4 into the glue groove, the fireproof sealant 4 is cured and formed into a frame-shaped rubber strip. On the one hand, the wall panel 2 and the outer frame 111 can be fixedly connected, and the bolts 31 and nuts 32 are assisted to strengthen the connection strength between the two. On the other hand, the formed fireproof sealant 4 can fill the gap between the wall panel 2 and the outer frame 111 to achieve the sealed connection between the two. Compared with other glues, the fireproof sealant 4 has good weather resistance and can still maintain its elasticity under severe cold and high temperature. Moreover, it has excellent flame retardancy, fire resistance and high temperature resistance. Not only that, the fireproof sealant 4 also has excellent water vapor penetration resistance, and the water absorption rate is lower than 0.01%, which helps to prevent damage caused by water penetration at the joint of the wall panel 2 and the outer frame 111. And the fireproof sealant 4 has a low odor, no pollution and meets the requirements of fire protection and environmental protection. After filling the fireproof sealant 4 in the glue groove, it can ensure the overall smoothness and flatness of the circumferential outer edge surface of the curtain wall composite fireproof board, thereby improving the product quality.

[0057] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
