Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation composite boards, in particular to a highly energy-efficient external wall thermal insulation composite board. Background Art

[0002] In the past, the thermal insulation measures of buildings were relatively simple and inefficient, with large energy consumption. With the emergence of the energy crisis and the enhancement of environmental awareness, higher requirements have been put forward for the thermal insulation performance of buildings. Traditional single thermal insulation materials, such as polystyrene foam boards, rock wool, etc., although having a certain thermal insulation effect, have problems such as low strength, poor fire resistance, and inconvenient construction. To overcome these problems, thermal insulation composite boards came into being. It combines the advantages of various materials and is usually composed of a thermal insulation core material and a protective surface layer. The progress of materials science provides a basis for the development of thermal insulation composite boards. New thermal insulation core materials, such as polyurethane foam, vacuum insulation panels, etc., have better thermal insulation performance and smaller thickness. At the same time, surface layer materials with high strength, corrosion resistance, and good fire resistance, such as metal plates, fiber-reinforced cement boards, calcium silicate boards, etc., enable the thermal insulation composite board to have sufficient strength, durability, and fire resistance while having excellent thermal insulation performance.

[0003] An external wall thermal insulation board usually consists of the following main structural parts: Thermal insulation core material: This is the core part of the thermal insulation board, responsible for providing the main thermal insulation performance. Adhesive layer: Located on both sides of the thermal insulation core material, used to firmly bond the core material to the protective surface layer. Protective surface layer: Covers the outer surface of the thermal insulation core material, providing protection and enhancing mechanical strength. Reinforcing material: Reinforcing materials such as fiberglass mesh may be added to the protective surface layer to increase the crack resistance and tensile strength of the surface layer. Anchor: Used to fix the thermal insulation board on the external wall of the building. Generally made of plastic or metal, it provides additional fixing force by being driven into the wall. Taking the common thin-plastered external wall thermal insulation system of polystyrene foam boards as an example, the polystyrene foam board is used as the thermal insulation core material, and adhesive mortar is applied on both sides to bond with the thin-plastered surface layer (including fiberglass mesh), and then it is fixed on the wall through anchors. In the rock wool thermal insulation board system, rock wool is used as the core material, and there may be a waterproof and breathable membrane on the surface, plus a thin-plastered surface layer and anchors for fixation.

[0004] In order to ensure the thermal insulation effect of the existing external thermal insulation wall, the thermal insulation materials generally used are polystyrene foam boards and polyurethane foam boards, but these materials are flammable and may contribute to the spread of fire in case of a fire. Moreover, during the construction process, the installation and fixation effect of the thermal insulation board is poor, easily causing the thermal insulation board to be hollow and fall off, resulting in high-altitude falling object accidents.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: an energy-efficient exterior wall thermal insulation composite board, which includes an adhesive layer 6. At the bottom end of the adhesive layer 6, a thermal insulation frame 2 is fixedly connected. At the top end inside the thermal insulation frame 2, a thermal insulation core material 4 is fixedly connected. At the bottom end inside the thermal insulation frame 2, a thermal insulation foam 5 is fixedly connected. At the top end of the adhesive layer 6, an explosion layer 7 is fixedly connected. At the top end of the explosion layer 7, a flame retardant layer 8 is fixedly connected. Inside the explosion layer 7, explosion cavities are equidistantly arranged, and explosion powder is filled inside the explosion cavities. When the exterior wall thermal insulation board catches fire, the thermal insulation core material 4 and the thermal insulation foam 5 inside the decorative board 1 and the thermal insulation frame 2 will generate high-temperature flames under the ignition of the fire source. At this time, the explosion powder inside the explosion layer 7 is heated to generate high-pressure gas, and the high-pressure gas ejects the entire adhesive layer 6, causing the flammable materials to break under the jet of the high-pressure gas generated by the explosion powder, reducing the spread of the fire.

[0028] Refer to Figure 1 - Figure 2 , at the four corners of the top end of the flame retardant layer 8, fixing tubes 11 are fixedly connected. In the middle of the inside of the fixing tubes 11, a fixing seat 13 is fixedly connected. In the middle of the fixing seat 13, a moving rod 15 is slidably connected. At the top of the inside of the fixing tubes 11, a claw seat 19 is fixedly connected. At the outer triangles of the claw seat 19, fixing claws 14 are rotatably connected. At the middle of the bottom end of the fixing claws 14, a connecting rod 18 is rotatably connected. At the middle of the outside of the moving rod 15, a pushing seat 16 is fixedly connected. A fixing spring 17 is sleeved on the middle and lower part of the outside of the moving rod 15. At the middle of the bottom end of the moving rod 15, a limiting seat 20 is fixedly connected. Under the action of the fixing spring 17 pushing the pushing seat 16, the moving rod 15 inside the fixing anchor causes the fixing claws 14 to open, so that the fixing claws 14 are firmly buckled in the fixing holes, enabling the external thermal insulation board to be firmly fixed on the exterior wall of the building.

[0029] Refer to Figure 1 - Figure 2 , at the bottom end of the thermal insulation frame 2, a decorative board 1 is fixedly connected. At the front end of the thermal insulation frame 2, a fixing buckle 10 is fixedly connected. At the rear end of the thermal insulation frame 2, a fixing block 9 is fixedly connected. Inside the thermal insulation frame 2, support plates 3 are fixedly connected equidistantly from front to back. The flame retardant layer 8 is made of gypsum raw materials, and a double-layer plastic fiber mesh is used for structural reinforcement inside the flame retardant layer 8. At the top end of the fixing tube 11, a guiding head 12 is fixedly connected. The decorative board 1 provides different decoration styles for the building wall. Workers open thermal insulation board fixing holes on the wall to be installed. Subsequently, under the guidance of the guiding head 12, the fixing anchor is accurately inserted into the fixing hole. The fixing block 9 and the fixing buckle 10 are closely combined to prevent external dust and rain from infiltrating and affecting the thermal insulation effect of the thermal insulation board. The gypsum board of the flame retardant layer 8 can prevent the flame from damaging the building wall.

[0030] Working principle: Workers drill fixing holes for thermal insulation boards on the wall to be installed. Subsequently, under the guidance of the guiding head 12, the fixing anchor is accurately inserted into the fixing hole. Then, the moving rod 15 inside the fixing anchor is pushed by the fixing spring 17 to push the pushing seat 16, causing the fixing claws 14 to open, so that the fixing claws 14 are firmly buckled in the fixing hole, enabling the external thermal insulation board to be firmly fixed on the exterior wall of the building. At the same time, the fixing block 9 and the fixing buckle 10 are closely combined to prevent external dust and rainwater from infiltrating and affecting the thermal insulation effect of the thermal insulation board. When the exterior wall thermal insulation board catches fire, the thermal insulation core material 4 and the thermal insulation foam 5 in the decorative board 1 and the thermal insulation frame 2 will generate high-temperature flames under the ignition of the fire source. At this time, the explosive powder in the explosion layer 7 is heated to generate high-pressure gas, and the high-pressure gas ejects the adhesive layer 6 as a whole, causing the flammable materials to break under the jet of the high-pressure gas generated by the explosion powder, reducing the spread of the fire. At the same time, the gypsum board of the flame retardant layer 8 prevents the flame from damaging the building wall.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
