Description

Technical Field

[0001] The present invention relates to the technical field of building thermal insulation, and more specifically, to a building exterior wall thermal insulation device. Background Art

[0002] Building exterior walls are part of the external structure of a building. They play the role of protecting, isolating and beautifying the building. With the continuous growth of people's economic level, people's pursuit of building exterior walls is no longer simply to protect, isolate and beautify the building, but more inclined to the role of thermal insulation, heat insulation, energy saving and environmental protection. Therefore, more and more buildings are beginning to adopt new types of building exterior walls.

[0003] New building exterior wall structures usually have certain advantages in thermal insulation, energy saving and environmental protection, but there are still problems such as cold bridge effect, complex construction, poor durability, difficult maintenance, high cost and poor fire resistance.

[0004] In the above-mentioned related technologies, the problems of poor insulation effect, cold bridge effect, poor durability, difficult maintenance, high cost and so on of the exterior walls of new buildings have been well solved. However, exterior walls with good insulation effect are usually accompanied by complex construction technology. The problem of how the exterior walls of new buildings in the related technologies can ensure their insulation effect while being easy to install and maintain has not been solved.

[0005] After searching, a Chinese patent with announcement number CN118292561A discloses a new building exterior wall insulation structure and construction method. The structure only needs to embed or install the connecting base in the wall, and then splice the insulation board on the connecting base. Due to the setting of the connecting mechanism, rapid docking and installation can be achieved. When the insulation board needs to be repaired, only the damaged insulation board needs to be replaced, which has the advantage of easy disassembly and assembly.

[0006] However, in actual use, this structure is not convenient enough for the disassembly and assembly of the insulation board. For example, after the insulation board is connected to the connecting base through the connecting mechanism, the connecting screw passing through the insulation board needs to be threadedly tightened by the connecting nut. During the overall operation process, a large number of tools are needed, and the disassembly and assembly are cumbersome, which increases the operator's stay time for high-altitude operations and increases the danger. Moreover, during the entire installation, the connecting screw needs to pass through the entire insulation board, affecting the aesthetics and insulation effect of the insulation board.

[0007] In view of the above situation, the present invention provides a building exterior wall thermal insulation device. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] As attached Figure 1-8 The building exterior wall insulation device shown includes an exterior wall body 1 and a plurality of connecting seats 2 and insulation boards 3 embedded in the exterior wall body 1. The connecting seats 2 are installed inside the exterior wall body 1 by embedding with mud, and the insulation boards 3 are installed on the surface of the connecting seats 2. An embedding groove 20 is opened on the surface of the exterior wall body 1. The connecting seats 2 and the insulation boards 3 are embedded and installed inside the exterior wall body 1 through the embedding groove 20. The insulation boards 3 are consistent with the horizontal plane of the exterior wall body 1, and each adjacent two insulation boards 3 are fitted together.

[0025] Specifically, in this structure, when installing the insulation device on the exterior wall body 1, it is necessary to reserve an embedding groove 20 on the surface of the exterior wall body 1. The depth of the embedding groove 20 needs to ensure that the insulation board 3 is in the same horizontal plane with the exterior wall body 1 after installation. First, the connecting seat 2 is installed in the embedded groove 20 reserved in advance on the exterior wall body 1 through mud, so that the connecting seat 2 is connected to the exterior wall body 1. Multiple insulation boards 3 are connected to the corresponding connecting seats 2 through a locking structure to ensure that the horizontal planes of the multiple insulation boards 3 are consistent. The locking structure facilitates the installation and disassembly of the insulation board 3 and the connecting seat 2, and it is convenient to install or disassemble and replace.

[0026] In this embodiment, as shown in the attached Figure 3 , 4As shown in Figure 5, the locking structure includes a plurality of support platforms 4, and first circular grooves 5 are provided at the four corners of the surface of the connecting seat 2, and a support platform 4 is fixedly connected to the inside of each first circular groove 5, and a round table seat 6 is fixedly provided on the surface of the support platform 4, and a guide rod 7 is provided on the surface of the round table seat 6, and a movable block 8 is provided on the outside of the guide rod 7, and a locking block 9 is provided at one end of the guide rod 7, and a first spring 10 is provided on the outside of the guide rod 7 between the movable block 8 and the locking block 9, and the cross-sectional shapes of the movable block 8 and the locking block 9 are both trapezoidal, and the movable block 8 and the locking block 9 are symmetrically distributed on the outside of the guide rod 7, wherein the movable block 8 is slidably connected to the outside of the guide rod 7, and the locking block 9 is fixedly connected to one end of the guide rod 7, and the two ends of the first spring 10 are fixedly connected to the movable block 8 and the locking block 9 respectively.

[0027] Specifically, this structure acts on the connecting seat 2 and is a part of the locking structure, which facilitates the subsequent installation and disassembly between the insulation board 3 and the connecting seat 2. Specifically, the support platform 4 and the truncated platform seat 6 installed inside the first circular groove 5 are used to support the guide rod 7. The relatively arranged and trapezoidal movable block 8 and the locking block 9 are both on the guide rod 7. The movable block 8 can slide on the outside of the guide rod 7 to facilitate the subsequent disassembly and unlocking of the insulation board 3. The locking block 9 is fixed at one end of the guide rod 7 to facilitate the subsequent locking connection of the insulation board 3. The first spring 10 outside the guide rod 7 has an elastic reset effect, which can ensure that the movable block 8 is reset after sliding outside the guide rod 7.

[0028] In this embodiment, as shown in the attached Figure 3 , 4 As shown in , 6 and 7, the locking structure also includes a plurality of sleeves 11. A second circular groove 12 is provided at the four corners of the back side of the insulation board 3. The plurality of sleeves 11 are respectively fixedly connected to the corresponding second circular grooves 12. A clearance groove 13 is provided at the end of the sleeve 11, and the clearance groove 13 is truncated. Locking components are provided on the inner walls on both sides of the sleeve 11. The locking components include a movable rod 14. A mounting hole 15 is provided through the inner wall of the sleeve 11. The movable rod 14 is slidably installed in the mounting hole 15. A fitting block 16 is fixedly provided at one end of the movable rod 14. The cross-sectional shape of the fitting block 16 is triangular. A guide ring 17 is fixedly connected to the end of the mounting hole 15. The movable rod 14 is slidably connected inside the guide ring 17. A limiting block 18 is provided at the other end of the movable rod 14. A second spring 19 is provided on the outside of the movable rod 14 between the fitting block 16 and the guide ring 17.

[0029] Specifically, the structure acts on the heat preservation board 3, and through the structural cooperation on the connecting seat 2, the heat preservation board 3 and the connecting seat 2 are quickly connected and disassembled. The sleeve 11 installed in the second circular groove 12 can be inserted into the first circular groove 5 as a whole. At this time, the fitting block 16 in the form of a triangular block will pass through the locking block 9 on the connecting seat 2, extend to the inside of the mounting hole 15 and push the movable rod 14 to slide inside the guide ring 17, so that the second spring 19 is squeezed. When the fitting block 16 is at the bottom of the locking block 9, the second spring 19 is reset after being squeezed, so that the fitting block 16 is at the bottom of the locking block 9 for locking operation, and the heat preservation board 3 and the connecting seat 2 are in a connected state; When the engaging block 16 continues to be extended to one side, the engaging block 16 will extend toward the movable block 8. Under the action of the second spring 19, the two engaging blocks 16 will extend to the outer wall of the movable block 8 and provide clamping force for the movable block 8, pulling the insulation board 3 outward. The engaging block 16 drives the movable block 8 to slide on the outside of the guide rod 7 and squeezes the first spring 10. When the movable block 8 and the locking block 9 are fitted, the two engaging blocks 16 will pass through the trapezoidal movable block 8 and the locking block 9 and disengage, thereby realizing the disassembly of the insulation board 3. The first spring 10 is reset after being squeezed, so that the movable block 8 returns to its initial state outside the guide rod 7.

[0030] In this embodiment, as shown in the attached Figure 8 As shown, the insulation board 3 specifically includes a base layer 30, an insulation layer 31, a protective layer 32 and a finishing layer 33 which are distributed in sequence. The base layer 30, the insulation layer 31, the protective layer 32 and the finishing layer 33 are an integrated structure. The insulation layer 31 is made of polyurethane foam, and the surface of the insulation layer 31 is covered with a waterproof and breathable membrane 34. The protective layer 32 is a glass fiber mesh cloth, and the finishing layer 33 is any one of an aluminum plate and a zinc plate.

[0031] Specifically, in this structure, the insulation board 3 is specifically composed of a base layer 30, an insulation layer 31, a protective layer 32 and a finishing layer 33, wherein the insulation layer 31 made of polyurethane foam has a high-performance insulation effect, and also has excellent thermal insulation performance, fire resistance and corrosion resistance. The waterproof and breathable membrane 34 is coated on the surface of the insulation layer 31 to improve the overall air permeability and waterproof performance of the insulation board 3. The waterproof and breathable membrane 34 can allow water vapor molecules to pass through, but prevents direct penetration of liquid water and air, thereby maintaining the dryness and insulation effect of the inside of the insulation layer 31. The protective layer 32 composed of glass fiber mesh cloth is mainly used to protect the insulation layer 31 from erosion by the external environment, such as wind, rain, ultraviolet rays, etc. The finishing layer 33 is specifically any one of an aluminum plate and a zinc plate, and has the characteristics of a strong sense of modernity and corrosion resistance.

[0032] Working principle of the present invention: In order to understand the technical solution of the present invention in detail, the above structure is described in detail. The present invention provides a building exterior wall insulation device, which is specifically used; First, an embedding groove 20 is reserved on the surface of the exterior wall body 1. The depth of the embedding groove 20 needs to ensure that the insulation board 3 is at the same level as the exterior wall body 1 after installation. The connecting seat 2 is first installed in the embedded groove 20 reserved in advance on the exterior wall body 1 through mud or other adhesives, and the connecting seat 2 is connected to the exterior wall body 1; When installing the insulation board 3, the operator aligns the second circular groove 12 with the first circular groove 5 and extends the sleeve 11 to the inside of the first circular groove 5. During this period, the two triangular fitting blocks 16 will pass through the trapezoidal locking block 9, and the inclined surface of the fitting block 16 will pass through the inclined surface of the locking block 9. At this time, the two fitting blocks 16 will be provided with thrust to both sides, and the fitting blocks 16 will extend into the corresponding mounting holes 15, and push the movable rod 14 to slide inside the guide ring 17, and cause the second spring 19 to be squeezed. When the second spring 19 is squeezed and reset, it is ensured that the two fitting blocks 16 are on the plane at the bottom of the locking block 9. At this time, the fitting blocks 16 and the locking block 9 are in a locked state. The final state is shown in the attached figure. Figure 3-4 As shown, the quick connection between the insulation board 3 and the connection seat 2 is completed, and then multiple insulation boards 3 are installed in the same way to ensure that the horizontal planes of each insulation board 3 are consistent; When the second spring 19 is reset, the two engaging blocks 16 clamp the two ends of the movable block 8. At this time, the operator can use the suction cup handle to pull the insulation board 3 outward. After the two engaging blocks 16 clamp the movable block 8, the movable block 8 is driven to slide on the outside of the guide rod 7 and squeeze the second spring 19. After the relatively arranged movable block 8 and the locking block 9 are docked, when the insulation board 3 is continued to be pulled, the two engaging blocks 16 will pass through the inclined surface of the movable block 8 and the locking block 9 in turn, and the disassembly operation of the insulation board 3 can be achieved. Figure 5-7 As shown; Generally speaking, the entire disassembly process does not require the disassembly of bolts, the assembly and disassembly of the insulation board 3 is quick, and the operator's stay time during high-altitude disassembly and assembly is reduced, thereby improving safety; In this structure, the insulation board 3 is specifically composed of a base layer 30, an insulation layer 31, a protective layer 32 and a finishing layer 33, wherein the insulation layer 31 made of polyurethane foam has a high-performance insulation effect, and also has excellent heat insulation, fire resistance and corrosion resistance. The waterproof breathable membrane 34 is coated on the surface of the insulation layer 31 to improve the overall air permeability and waterproof performance of the insulation board 3. The waterproof breathable membrane 34 allows water vapor molecules to pass through, but prevents direct penetration of liquid water and air, thereby maintaining the dryness and insulation effect of the inside of the insulation layer 31. The protective layer 32 composed of glass fiber mesh cloth is mainly used to protect the insulation layer 31 from erosion by the external environment, such as wind, rain, ultraviolet rays, etc. The finishing layer 33 is specifically any one of an aluminum plate and a zinc plate, and has the characteristics of a strong sense of modernity and corrosion resistance.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
