Description

Technical Field

[0001] This utility model relates to the field of insulation board technology, and in particular to a double-sided composite fireproof and recyclable insulation board. Background Technology

[0002] Double-sided composite fireproof and renewable insulation board is a new type of building insulation material that integrates four core characteristics: double-sided composite structure, fire safety performance, renewable raw material utilization, and thermal insulation function. Its design purpose is to solve the shortcomings of traditional insulation boards in terms of fire resistance, environmental protection, and durability, and to meet the comprehensive needs of modern buildings for safety, energy saving, and greenness. It is widely used in insulation projects such as building exterior walls, roofs, and interior partitions.

[0003] However, existing double-sided composite fireproof and recyclable insulation boards have the following disadvantages: (1) Some traditional insulation boards are mostly single insulation layer structures, or only a simple fireproof layer is set on one side. When there is high temperature or open flame in the outside, the fireproof layer of the traditional insulation board is difficult to effectively block the spread of flame and the transmission of high temperature. The internal insulation material is easily exposed to the high temperature environment, which will melt, burn, or even release toxic gases. This will not only cause the insulation function to fail instantly, but also cause serious safety hazards and cannot meet the basic requirements of the building for fire protection level. (2) Some traditional insulation boards do not have a dedicated positioning structure when splicing. They often need to rely on external bolts, rivets and other complex fasteners to achieve basic positioning. This is not only cumbersome to operate, but also easy to cause misalignment of the board due to the installation deviation of the fasteners.

[0004] Therefore, this utility model provides a double-sided composite fireproof and renewable thermal insulation board. Utility Model Content

[0005] (a) Technical problems to be solved The problem solved by this utility model is to provide a highly practical double-sided composite fireproof and recyclable insulation board, which solves the problems mentioned in the background art that some traditional insulation boards are mostly single insulation layer structures, or only have a simple fireproof layer on one side, and that some traditional insulation boards do not have a dedicated positioning structure when spliced ​​together.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a double-sided composite fireproof and renewable thermal insulation board, comprising a board body, wherein a thermal insulation layer and a reinforcing layer are sequentially arranged from the inside to the outside of the board body; a first fireproof layer is composited on the side of the thermal insulation layer away from the reinforcing layer; a second fireproof layer is composited on the side of the reinforcing layer away from the thermal insulation layer; a protrusion is integrally formed on one side of the board body; a positioning rod is fixedly connected to the center of the protrusion; a groove adapted to the protrusion is formed on the side of the board body away from the protrusion; a positioning groove adapted to the positioning rod is formed on the inner wall of the groove; an embedding block is fixedly connected to both ends of the board body; and embedding grooves matching the embedding blocks are formed at the other two ends of the board body; and the thermal insulation layer is made of renewable thermal insulation material.

[0007] Optionally, the first fireproof layer and the second fireproof layer are made of the same material. Both the first fireproof layer and the second fireproof layer are made of glass fiber reinforced cement board. The use of the same glass fiber reinforced cement board for the first fireproof layer and the second fireproof layer can rely on the high temperature resistance and non-combustible properties of the material to simultaneously block external flames and high temperatures, avoid direct exposure and damage to the insulation layer, and improve the fire safety level of the board. Moreover, the same material can avoid uneven interlayer stress caused by differences in thermal expansion coefficients, reduce cracking and peeling, and ensure the stability of the composite structure of the board.

[0008] Optionally, the insulation layer is a recycled polyurethane foam layer or a recycled extruded polystyrene foam layer. The insulation layer has a uniformly distributed closed-cell structure inside. The recycled polyurethane foam or recycled extruded polystyrene foam in the insulation layer, combined with the uniformly distributed closed-cell structure inside, can reduce air convection and heat conduction, enhance the insulation effect of the panel, and reduce building energy consumption. At the same time, the use of recycled materials reduces the consumption of non-renewable resources and pollution, which meets environmental protection requirements.

[0009] Optionally, the reinforcing layer is made of galvanized steel wire mesh or fiberglass mesh. The reinforcing layer is fixedly connected to the insulation layer and the second fireproof layer respectively by epoxy resin adhesive. The reinforcing layer is tightly connected to the insulation layer and the second fireproof layer by epoxy resin adhesive, which can prevent interlayer peeling. Its mesh structure can disperse external forces and avoid cracking and deformation of the panel. Moreover, the galvanized steel wire mesh is corrosion resistant and the fiberglass mesh is aging resistant, which can be adapted to different use environments and extend the service life of the panel.

[0010] Optionally, the positioning rod is made of stainless steel, and its diameter is slightly smaller than the inner diameter of the positioning groove. The stainless steel positioning rod has strong corrosion resistance and can maintain its positioning function for a long time, preventing loosening at the joint. The design of the diameter being slightly smaller than the positioning groove not only facilitates the smooth insertion of the positioning rod and improves installation efficiency, but also ensures the splicing accuracy of the panels and prevents misalignment.

[0011] Optionally, the cross-section of the embedded block is rectangular, and the inner wall of the embedded groove is coated with a wear-resistant coating. The rectangular cross-section of the embedded block and the embedded groove have a large contact area, which enhances splicing constraints and reduces heat leakage and water seepage in the gaps. The wear-resistant coating on the inner wall of the embedded groove can reduce frictional wear between the embedded block and the embedded groove during splicing, installation and use, ensure splicing stability and reduce maintenance costs.

[0013] 2. This double-sided composite fireproof and recyclable insulation board, through the setting of protrusions, positioning rods, grooves and positioning slots, achieves precise positioning of the board in terms of splicing and installation through a multi-splicing structure of protrusion-groove plus positioning rod-positioning slot plus embedding block-embedded slot. It does not require additional complex fasteners, simplifies the installation process and improves construction efficiency. Moreover, after splicing, the various mating structures restrain each other, which can effectively prevent loosening and displacement at the splicing points, ensure the integrity and sealing of the splicing, and avoid the loss of insulation performance or damage to the board due to water vapor seepage caused by splicing gaps.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a double-sided composite fireproof and renewable thermal insulation board, including a board body 1. The board body 1 is provided with a thermal insulation layer 3 and a reinforcing layer 4 from the inside to the outside. A first fireproof layer 2 is composited on the side of the thermal insulation layer 3 away from the reinforcing layer 4, and a second fireproof layer 5 is composited on the side of the reinforcing layer 4 away from the thermal insulation layer 3. A protrusion 6 is integrally formed on one side of the board body 1. A positioning rod 7 is fixedly connected to the middle of the protrusion 6. A groove 8 adapted to the protrusion 6 is opened on the side of the board body 1 away from the protrusion 6. A positioning groove 9 adapted to the positioning rod 7 is opened on the inner wall of the groove 8. An embedding block 10 is fixedly connected to both ends of the board body 1. An embedding groove 11 matching the embedding block 10 is opened at the other two ends of the board body 1. The thermal insulation layer 3 is made of renewable thermal insulation material. The first fireproof layer 2 and the second fireproof layer 5 are made of the same material. Both the first fireproof layer 2 and the second fireproof layer 5 are made of glass fiber reinforced cement board. The use of the same glass fiber reinforced cement board for the first fireproof layer 2 and the second fireproof layer 5 can rely on the high temperature resistance and non-combustible properties of the material to simultaneously block external flames and high temperatures, prevent the insulation layer 3 from being directly exposed and damaged, and improve the fire safety level of the board 1. Moreover, the same material can avoid uneven interlayer stress caused by the difference in thermal expansion coefficient, reduce cracking and peeling, and ensure the stability of the composite structure of the board 1. The insulation layer 3 is a recycled polyurethane foam layer or a recycled extruded polystyrene foam layer. The insulation layer 3 has a uniformly distributed closed-cell structure. The recycled polyurethane foam or recycled extruded polystyrene foam in the insulation layer 3, combined with the uniformly distributed closed-cell structure inside, can reduce air convection and heat conduction, enhance the insulation effect of the panel 1, and reduce building energy consumption. At the same time, the use of recycled materials reduces the consumption of non-renewable resources and pollution, which meets environmental protection requirements. The reinforcing layer 4 is made of galvanized steel wire mesh or fiberglass mesh. The reinforcing layer 4 is fixedly connected to the insulation layer 3 and the second fireproof layer 5 respectively by epoxy resin adhesive. The reinforcing layer 4 is tightly connected to the insulation layer 3 and the second fireproof layer 5 by epoxy resin adhesive, which can prevent interlayer peeling. Its mesh structure can disperse external forces and prevent the panel 1 from cracking and deforming. Moreover, the galvanized steel wire mesh is corrosion resistant and the fiberglass mesh is aging resistant, which can be adapted to different use environments and extend the service life of the panel 1. The positioning rod 7 is made of stainless steel. The diameter of the positioning rod 7 is slightly smaller than the inner diameter of the positioning groove 9. The stainless steel positioning rod 7 is highly corrosion resistant and can maintain the positioning function for a long time, preventing loosening at the splicing point. The design with a diameter slightly smaller than the positioning groove 9 not only facilitates the smooth insertion of the positioning rod 7 and improves the installation efficiency, but also ensures the splicing accuracy of the plate 1 and prevents misalignment. The embedded block 10 has a rectangular cross-section, and the inner wall of the embedded groove 11 is coated with a wear-resistant coating. The rectangular cross-section of the embedded block 10 and the embedded groove 11 have a large contact area, which enhances the splicing constraint and reduces heat leakage and water seepage in the gaps. The wear-resistant coating on the inner wall of the embedded groove 11 can reduce the frictional wear between the embedded block 10 and the embedded groove 11 during splicing, installation and use, ensure splicing stability and reduce maintenance costs.

[0018] In this invention, the working steps of the device are as follows: First step: When high temperature or open flame occurs in the outside, the first fireproof layer 2 and the second fireproof layer 5 on both sides give priority to fire barrier function. Relying on the high temperature resistance and non-combustible properties of the materials, they block the spread of flames and the transmission of high temperature. The middle insulation layer 3, with its evenly distributed closed bubble structure, reduces air convection and heat conduction, achieves heat barrier, and maintains the temperature difference between the two sides of the board 1 to achieve the insulation effect. The reinforcement layer 4 is tightly connected to the insulation layer 3 and the second fireproof layer 5 through epoxy resin adhesive, which not only enhances the bonding strength of each layer and prevents interlayer peeling, but also improves the overall structural stability of the board 1 and avoids deformation and cracking when subjected to stress or temperature changes. The second step: In terms of splicing and installation, the multi-sponge structure of protrusion 6-groove 8 plus positioning rod 7-positioning groove 9 plus embedding block 10-embedding groove 11 can achieve precise positioning of panel 1 without the need for additional complex fasteners, simplifying the installation process and improving construction efficiency; and after splicing, the various mating structures constrain each other, which can effectively prevent loosening and displacement at the splicing points, ensure the integrity and sealing of the splicing, and avoid the reduction of thermal insulation performance or water vapor seepage damage to panel 1 due to splicing gaps.
