Description

Technical Field

[0001] This application belongs to the technical field of thermal insulation structures, specifically relating to a prefabricated thermal insulation structure that can be installed quickly. Background Technology

[0002] With the promotion and application of energy-efficient buildings, insulation boards are usually installed on the exterior walls during the construction of modern residential buildings to reduce heat transfer between indoors and outdoors, achieve the effect of heat preservation in winter and heat insulation in summer, reduce the energy consumption of air conditioning and heating systems, and thus achieve the effect of saving energy costs.

[0003] In related technologies, such as Chinese utility model patent with publication number CN222716256U, a green building insulation board that is easy to install is disclosed. It includes an exterior wall, a first insulation board, and a second insulation board. Both the first and second insulation boards are set on the front side of the exterior wall. The second insulation board is set on top of the first insulation board. The top of the first and second insulation boards are fixedly connected with protrusions, and the bottom is provided with grooves corresponding to the protrusions. The first and second insulation boards are interlocked with each other. The bottom of the first insulation board is provided with a load-bearing block, and the top of the second insulation board is provided with a pressing block. Both the load-bearing block and the pressing block are fixedly connected to the exterior wall by expansion bolts. The top of the load-bearing block has a protrusion that extends to the groove at the bottom of the first insulation board. The bottom of the pressing block has a notch that fits onto the surface of the protrusion on the top of the second insulation board.

[0004] When installing the above-mentioned insulation structure, first fix the load-bearing block to the external wall using expansion bolts, then apply adhesive to the back of the first and second insulation boards, and then assemble the first and second insulation boards. The first insulation board is placed on top of the load-bearing block, and the second insulation board is assembled with the protrusion on top of the first insulation board through the groove at its bottom. After completion, fix the clamping block to the external wall using expansion bolts. At this time, the clamping block is located on top of the second insulation board. After the assembly of the first and second insulation boards is completed, first fix the anchors to the first and second insulation boards using expansion bolts, and then fix the anchors to the external wall using expansion bolts to complete the installation of the insulation boards.

[0005] The inventors believe that when installing the above-mentioned insulation structure, the load-bearing blocks, clamping blocks and anchors need to be installed separately, which makes the installation steps of the insulation board more complicated and thus affects the installation efficiency of the insulation board. Utility Model Content

[0006] This application provides a prefabricated insulation structure that can be installed quickly, thereby improving the installation efficiency of insulation structures.

[0007] The technical solution adopted in this application is as follows:

[0008] A prefabricated thermal insulation structure for quick installation includes an insulation board and a reinforcing member disposed on the insulation board. The rigidity of the insulation board is less than that of the reinforcing member. The insulation board has an inner end face that conforms to an exterior wall and an outer end face opposite to the inner end face. The reinforcing member has a tube through which expansion nails pass. The tube passes through the insulation board and is perpendicular to the inner end face. The end of the tube away from the reinforcing member is flush with the inner end face.

[0009] By adopting the above technical solution, when installing the prefabricated insulation structure in this application, firstly apply adhesive to the inner end face of the insulation board, and then attach the insulation board to the exterior wall so that the inner end face of the insulation board is bonded to the exterior wall by the adhesive. Then, use an impact drill to drill holes in the exterior wall through the pipe. After drilling, insert expansion nails into the holes in the exterior wall through the pipe, and then tighten the screws of the expansion nails so that the nail heads of the expansion nails are pressed against the reinforcement. The insulation board is fixedly installed to the exterior wall by using the adhesive and expansion nails to ensure the connection stability between the insulation board and the exterior wall.

[0010] In summary, when installing the prefabricated insulation structure in this application, it is only necessary to apply adhesive to the insulation board, make holes in the exterior wall, and install expansion nails. Compared with the prior art, which requires the use of load-bearing blocks, clamping blocks, and anchors to fix the insulation board, this simplifies the installation steps of the prefabricated insulation structure, thereby improving the installation efficiency and reducing the installation difficulty.

[0011] In addition, since the rigidity of the insulation board is less than that of the reinforcement and the end of the tube away from the reinforcement is flush with the inner end face, after the insulation board is installed on the exterior wall, the end of the tube away from the reinforcement can abut against the exterior wall, so that the tube supports the reinforcement. This prevents the reinforcement from moving towards the exterior wall under the action of the expansion nail and squeezing the insulation board. This avoids the insulation board from deforming due to the squeezing force of the reinforcement, thus ensuring the shape and structural stability of the insulation board and ensuring the bonding area between the insulation board and the exterior wall through the adhesive.

[0012] Optionally, the reinforcing member is located inside the insulation board, and the outer end face is provided with a receiving hole for accommodating the expansion nail head corresponding to the pipe body.

[0013] By adopting the above technical solution, since the reinforcement is located inside the insulation board, the connection stability between the reinforcement and the insulation board is increased. At the same time, the reinforcement can be hidden inside the insulation board to improve the appearance quality of the insulation board. In addition, the reinforcement can also be used to increase the structural strength of the insulation board to ensure the connection stability between the insulation board and the exterior wall. Furthermore, since the outer end face is provided with a receiving hole corresponding to the pipe body, when the insulation board is fixed with expansion nails, the nail head can be hidden in the receiving hole to ensure the flatness of the outer end face of the insulation board, so as to facilitate the installation of decorative panels on the side of the insulation board away from the exterior wall.

[0014] Optionally, the reinforcement member has a clearance opening that penetrates the reinforcement member in the thickness direction.

[0015] By adopting the above technical solution, since the reinforcement has a clearance opening that penetrates the reinforcement in the thickness direction, the insulation boards on both sides of the reinforcement can be connected together in the clearance opening, thereby further increasing the connection stability between the reinforcement and the insulation board, and further improving the fixing effect of the prefabricated insulation structure.

[0016] Optionally, the reinforcement has a support tube located in the receiving hole, the diameter of the support tube being larger than the diameter of the tube body, so that the head of the expansion nail can extend into the support tube.

[0017] By adopting the above technical solution, since the reinforcement has a support tube located in the receiving hole, the support tube can support the hole wall of the receiving hole, thereby increasing the stability of the insulation board at the receiving hole and avoiding the situation where the insulation board at the receiving hole is damaged due to lack of support, thus ensuring the structural stability of the insulation board; and since the diameter of the support tube is larger than the diameter of the tube body, the nail head of the expansion nail used to fix the insulation board can be inserted into the support tube, so that the nail head of the expansion nail can be hidden in the support tube.

[0018] Optionally, the prefabricated insulation structure further includes a decorative panel disposed on the outer end face, the support tube is provided with a mating part, and the decorative panel is provided with a snap-fit ​​part corresponding to the mating part, the snap-fit ​​part being able to snap-fit ​​with the mating part.

[0019] By adopting the above technical solution, after the insulation board is installed to the exterior wall using adhesive and expansion nails, the decorative panel is then installed. First, the snap-fit ​​part on the decorative panel is aligned with the mating part on the support tube. Then, a pushing force is applied to the decorative panel towards the side where the insulation board is located, so that the snap-fit ​​part and the mating part snap together. This allows the device panel to be installed on the side of the insulation board away from the exterior wall. During the installation of the decorative panel, only pressing is required, thereby reducing the installation difficulty of the decorative panel and ensuring the connection stability between the decorative panel and the insulation board.

[0020] Optionally, the mating part is an annular rib provided at the opening of the support tube, and the snap-fit ​​part is a snap-fit ​​arm provided on the decorative panel, the side of the snap-fit ​​arm having a snap-fit ​​protrusion that can snap-fit ​​with the annular rib.

[0021] By adopting the above technical solution, when installing the decorative panel, first align the snap-fit ​​arm with the annular rib, then apply a pushing force to the decorative panel in the direction of the insulation board, thereby causing the decorative panel to move in the direction of the insulation board, so that the snap-fit ​​arm extends into the support tube, and the snap-fit ​​protrusion engages with the annular rib, thus completing the installation of the decorative panel.

[0022] Optionally, the inner diameter of the annular rib gradually increases in the direction away from the tube body, and the outer side of the snap-fit ​​protrusion is provided with a guide surface that can cooperate with the inner circumferential surface of the annular rib.

[0023] By adopting the above technical solution, the inner diameter of the annular rib gradually increases in the direction away from the pipe body, thereby increasing the inner diameter of the end of the annular rib away from the pipe body. This makes it easier for the snap-fit ​​protrusion to pass over the annular rib and extend into the interior of the support pipe. The outer side of the snap-fit ​​protrusion is provided with a guide surface that can cooperate with the inner circumferential surface of the annular rib, thereby reducing the size of the end of the snap-fit ​​protrusion away from the decorative panel. This makes it easier for the snap-fit ​​protrusion to pass over the annular rib and extend into the interior of the support pipe, thus achieving the effect of facilitating the snap-fit ​​arm to be snapped together with the annular rib. At the same time, the cooperation between the guide surface and the inner circumferential surface of the annular rib can also guide the deformation direction of the snap-fit ​​arm, further facilitating the installation of the decorative panel onto the side of the insulation board away from the exterior wall.

[0024] Optionally, multiple snap-fit ​​arms are provided at circumferential intervals along the annular rib.

[0025] By adopting the above technical solution, since multiple snap-fit ​​arms are arranged at intervals along the circumference of the annular rib, the number of snap-fit ​​points between the decorative panel and the reinforcement is increased, thereby further increasing the stability of the decorative panel.

[0026] Optionally, the decorative panel has an annular groove on its periphery, the annular groove extending circumferentially along the decorative panel, and a sealing ring is provided in the annular groove, at least a portion of the sealing ring being able to protrude from the side of the decorative panel.

[0027] By adopting the above technical solution, since a sealing ring is provided in the annular groove, the sealing rings on the two adjacent decorative panels can contact each other and deform to seal the gap between the two adjacent decorative panels, thereby increasing the sealing performance between the two adjacent decorative panels and preventing rainwater from entering the decorative panel and contacting the insulation board on the side of the decorative panel facing the outer wall through the gap between the two adjacent decorative panels.

[0028] Optionally, the reinforcement has a central region located at the center of the insulation board and a side region located on the side of the insulation board, and the pipe body is disposed in the central region and the side region.

[0029] By adopting the above technical solution, since the pipe body is located in the central area and the side area, the expansion joint can be fixed in the center and side positions of the insulation board, thereby achieving the fixation of the insulation board in the center and side positions and improving the fixing effect of the insulation board.

[0030] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0031] 1. The prefabricated insulation structure in this application includes an insulation board and a reinforcing member disposed on the insulation board. The rigidity of the insulation board is less than that of the reinforcing member. The insulation board has an inner end face that adheres to the exterior wall and an outer end face opposite to the inner end face. The reinforcing member has a tube through which expansion nails pass. The tube passes through the insulation board and is perpendicular to the inner end face. The end of the tube away from the reinforcing member is flush with the inner end face. Thus, when installing the prefabricated insulation structure in this application, it is only necessary to apply adhesive to the insulation board, make holes in the exterior wall, and install expansion nails. Compared with the prior art, which requires the use of load-bearing blocks, clamping blocks, and anchors to fix the insulation board, the installation steps of the prefabricated insulation structure are simplified, thereby improving the installation efficiency of the prefabricated insulation structure and reducing the installation difficulty of the prefabricated insulation structure.

[0032] 2. The reinforcement in this application is located inside the insulation board, thereby increasing the connection stability between the reinforcement and the insulation board. At the same time, it allows the reinforcement to be hidden inside the insulation board, thereby improving the appearance quality of the insulation board. In addition, the reinforcement can also be used to increase the structural strength of the insulation board to ensure the connection stability between the insulation board and the exterior wall. The outer end face is provided with a receiving hole for accommodating the head of the expansion nail to ensure the flatness of the outer end face of the insulation board, so as to facilitate the installation of the decorative panel on the side of the insulation board away from the exterior wall.

[0033] 3. The reinforcement component in this application has a clearance opening that extends through the thickness of the reinforcement component, thereby allowing the insulation boards on both sides of the reinforcement component to be connected together in the clearance opening, which further increases the connection stability between the reinforcement component and the insulation board, and further enhances the fixing effect of the prefabricated insulation structure.

[0047] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of this application.

[0050] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

[0052] Reference Figures 1 to 10 A prefabricated thermal insulation structure for quick installation is disclosed, which includes an insulation board 1 and a reinforcement member 2 disposed on the insulation board 1. The rigidity of the insulation board 1 is less than that of the reinforcement member 2. The insulation board 1 has an inner end face that fits against the outer wall and an outer end face opposite to the inner end face. The reinforcement member 2 has a tube 21 through which an expansion nail 4 passes. The tube 21 passes through the insulation board 1 and is disposed perpendicular to the inner end face. The end of the tube 21 away from the reinforcement member 2 is flush with the inner end face.

[0053] When installing the prefabricated insulation structure in this application, first apply adhesive to the inner end face of the insulation board 1, and then attach the insulation board 1 to the exterior wall so that the inner end face of the insulation board 1 is bonded to the exterior wall by the adhesive. Then, use an impact drill to drill holes in the exterior wall through the pipe body 21. After drilling, insert the expansion nail 4 into the hole in the exterior wall through the pipe body 21, and then tighten the screw of the expansion nail 4 so that the nail head of the expansion nail 4 is pressed against the reinforcement 2. The insulation board 1 is fixedly installed to the exterior wall by using the adhesive and the expansion nail 4 to ensure the connection stability between the insulation board 1 and the exterior wall.

[0054] In summary, when installing the prefabricated insulation structure in this application, it is only necessary to apply adhesive to the insulation board 1, make holes in the exterior wall, and install expansion nails 4. Compared with the prior art, which requires the use of load-bearing blocks, clamping blocks, and anchors to fix the insulation board 1, the installation steps of the prefabricated insulation structure are simplified, thereby improving the installation efficiency of the prefabricated insulation structure and reducing the installation difficulty of the prefabricated insulation structure.

[0055] In addition, since the rigidity of the insulation board 1 is less than that of the reinforcement 2 and the end of the tube 21 away from the reinforcement 2 is flush with the inner end face, after the insulation board 1 is installed on the exterior wall, the end of the tube 21 away from the reinforcement 2 can abut against the exterior wall, so that the tube 21 supports the reinforcement 2, thereby preventing the reinforcement 2 from moving towards the exterior wall under the action of the expansion nail 4 and squeezing the insulation board 1. This avoids the insulation board 1 from deforming due to the squeezing force of the reinforcement 2, thus ensuring the shape and structural stability of the insulation board 1, and ensuring the bonding area between the insulation board 1 and the exterior wall through the adhesive.

[0056] The better one is to refer to Figure 7 The pipe body 21 is provided with multiple sections at intervals to increase the number of connection points between the insulation board 1 and the outer wall through the expansion nails 4, thereby increasing the fixing stability of the insulation board 1.

[0057] This application does not specify the material of the insulation board 1, which can be made of polystyrene foam, rock wool, glass wool, polyurethane, etc.

[0058] This application does not specifically limit the material of the reinforcement 2. Preferably, the reinforcement 2 is made of rigid plastic to ensure the structural strength of the reinforcement 2, thereby ensuring the connection stability between the insulation board 1 and the exterior wall. In other embodiments, the reinforcement 2 can also be made of other metal materials such as iron and aluminum.

[0059] This application does not specifically limit the relative positional relationship between the reinforcement 2 and the insulation board 1. Preferably, refer to Figures 1 to 3The reinforcement 2 is located inside the insulation board 1, and its outer end face is provided with a receiving hole 11 for accommodating the head of the expansion nail 4 corresponding to the pipe body 21.

[0060] Since the reinforcement 2 is located inside the insulation board 1, the connection stability between the reinforcement 2 and the insulation board 1 is increased. At the same time, the reinforcement 2 can be hidden inside the insulation board 1 to improve the appearance quality of the insulation board 1. In addition, the reinforcement 2 can also be used to increase the structural strength of the insulation board 1 to ensure the connection stability between the insulation board 1 and the exterior wall. Since the outer end face is provided with a receiving hole 11 corresponding to the pipe body 21, when the expansion nail 4 is used to fix the insulation board 1, the nail head of the expansion nail 4 can be hidden in the receiving hole 11 to ensure the flatness of the outer end face of the insulation board 1, so as to facilitate the installation of the decorative panel 3 on the side of the insulation board 1 away from the exterior wall.

[0061] Furthermore, refer to Figure 6 and Figure 7 The reinforcement 2 has a clearance opening 23, which penetrates the reinforcement 2 in the thickness direction, thereby allowing the insulation boards 1 on both sides of the reinforcement 2 to be connected together in the clearance opening 23, so as to further increase the connection stability between the reinforcement 2 and the insulation board 1, and further improve the fixing effect of the prefabricated insulation structure.

[0062] This application does not specify the number of clearance openings 23. Preferably, multiple clearance openings 23 are evenly spaced along the circumference of the reinforcement 2, and each clearance opening 23 is triangular to ensure the connection stability between the reinforcement 2 and the insulation board 1. Of course, in other embodiments, only one clearance opening 23 or other numbers may be provided.

[0063] Furthermore, refer to Figures 2 to 6 The reinforcement 2 has a support tube 22 located in the receiving hole 11. The diameter of the support tube 22 is larger than the diameter of the tube body 21 so that the head of the expansion nail 4 can extend into the support tube 22.

[0064] It is understandable that the outer peripheral surface of the support tube 22 abuts against the wall of the receiving hole 11 so that the support tube 22 can support the wall of the receiving hole 11, thereby increasing the structural strength of the insulation board 1 at the receiving hole 11 and increasing the stability of the insulation board 1 at the receiving hole 11, so as to avoid the insulation board 1 at the receiving hole 1 from being damaged due to lack of support, thereby ensuring the structural stability of the insulation board 1; and since the diameter of the support tube 22 is larger than the diameter of the tube body 21, the nail head of the expansion nail 4 used to fix the insulation board 1 can be inserted into the support tube 22 so that the nail head of the expansion nail 4 can be hidden in the support tube 22.

[0065] Furthermore, refer to Figures 1 to 3The prefabricated insulation structure also includes a decorative panel 3 on the outer end face, a supporting pipe 22 with a mating part, and a snap-fit ​​part on the decorative panel 3 corresponding to the mating part, which can snap-fit ​​with the mating part.

[0066] After the insulation board 1 is installed to the exterior wall using adhesive and expansion nails 4, the decorative panel 3 is then installed. First, the snap-fit ​​part on the decorative panel 3 is aligned with the mating part on the support tube 22. Then, a pushing force is applied to the decorative panel 3 toward the side where the insulation board 1 is located, so that the snap-fit ​​part and the mating part snap together. This allows the device to be installed on the side of the insulation board 1 away from the exterior wall. During the installation of the decorative panel 3, only the decorative panel 3 needs to be pressed, which reduces the installation difficulty of the decorative panel 3 and ensures the connection stability between the decorative panel 3 and the insulation board 1.

[0067] Furthermore, by concealing the head of the expansion nail 4 within the support tube 22, the decorative panel 3 can abut against the outer end face of the insulation board 1, thereby enabling the insulation board 1 to support the decorative panel 3 and increase the stability of the decorative panel 3.

[0068] The better one is to refer to Figure 2 and Figure 3 The end of the support tube 22 away from the reinforcement 2 is flush with the outer end face of the insulation board 1. On the one hand, the support tube 22 can avoid the decorative board 3, so that the decorative board 3 can abut against the outer end face of the insulation board 1, thereby increasing the stability of the decorative board 3. On the other hand, the support tube 22 can support the decorative board 3 to avoid the decorative board 3 from exerting pressure on the insulation board 1.

[0069] This application does not specifically limit the structure of the mating part and the snap-fit ​​part. Preferably, the mating part is an annular rib 221 provided at the opening of the support tube 22, and the snap-fit ​​part is a snap-fit ​​arm 31 provided on the decorative panel 3. The side of the snap-fit ​​arm 31 has a snap-fit ​​protrusion 311 that can snap-fit ​​with the annular rib 221.

[0070] It is understood that the annular rib 221 is located inside the support tube 22, and the annular rib 221 is located at the end of the support tube 22 away from the reinforcement member 2.

[0071] When installing the decorative panel 3, first align the snap-fit ​​arm 31 with the annular rib 221, then apply a pushing force to the decorative panel 3 in the direction of the insulation board 1, thereby causing the decorative panel 3 to move in the direction of the insulation board 1, so that the snap-fit ​​arm 31 extends into the support tube 22, and the snap-fit ​​protrusion 311 engages with the annular rib 221, thus completing the installation of the decorative panel 3.

[0072] Furthermore, refer to Figure 5The inner diameter of the annular rib 221 gradually increases in the direction away from the pipe body 21, thereby increasing the inner diameter of the end of the annular rib 221 away from the pipe body 21, so that the snap-fit ​​protrusion 311 can more easily pass over the annular rib 221 and extend into the interior of the support pipe 22; see reference Figure 9 The outer side of the snap-fit ​​protrusion 311 is provided with a guide surface 312 that can cooperate with the inner circumferential surface of the annular rib 221, thereby reducing the size of the end of the snap-fit ​​protrusion 311 away from the decorative panel 3, so that the snap-fit ​​protrusion 311 can more easily pass over the annular rib 221 and extend into the interior of the support tube 22, thereby achieving the effect of facilitating the snap-fit ​​arm 31 and the annular rib 221 to snap together. At the same time, the cooperation between the guide surface 312 and the inner circumferential surface of the annular rib 221 can also guide the deformation direction of the snap-fit ​​arm 31, so as to further facilitate the installation of the decorative panel 3 onto the side of the insulation board 1 away from the outer wall.

[0073] Furthermore, refer to Figure 10 Multiple snap-fit ​​arms 31 are provided at intervals along the circumference of the annular rib 221, thereby increasing the snap-fit ​​points between the decorative panel 3 and the reinforcement 2, and further increasing the stability of the decorative panel 3.

[0074] In other implementation examples, both the snap-fit ​​part and the mating part can be block structures that can snap-fit ​​and mate with each other.

[0075] Furthermore, refer to Figure 2 , Figure 3 and Figure 9 A groove 32 is provided around the decorative panel 3. The groove 32 extends around the decorative panel 3. A sealing ring 321 is provided in the groove 32. At least a portion of the sealing ring 321 can protrude from the side of the decorative panel 3.

[0076] It is understandable that the annular groove 32 is provided on the side of the decorative panel 3 and extends along the circumference of the decorative panel 3.

[0077] It should be noted that when performing thermal insulation construction on the exterior wall, multiple prefabricated insulation structures need to be spliced ​​together so that the entire exterior wall is covered with prefabricated insulation structures.

[0078] Because a sealing ring 321 is provided in the annular groove 32, the sealing rings 321 on the two adjacent decorative panels 3 can contact each other and deform to seal the gap between the two adjacent decorative panels 3, thereby increasing the sealing performance between the two adjacent decorative panels 3 and preventing rainwater from entering the decorative panel 3 and contacting the insulation board 1 on the side of the decorative panel 3 facing the outer wall through the gap between the two adjacent decorative panels 3.

[0079] Regarding the structure where the insulation board 1 is made of a water-absorbing material, if rainwater enters the side of the decorative board 3 facing the exterior wall through the two adjacent decorative boards 3, the insulation board 1 will absorb the rainwater, thereby increasing the weight of the insulation board 1 and increasing the risk of the insulation board 1 falling off the exterior wall. However, by setting the sealing ring 321 in this application, the risk of the insulation board 1 falling off can be greatly avoided.

[0080] This application does not specifically limit the formation method of the annular groove 32. For the scheme where the decorative panel 3 is formed by a plate with a certain thickness, the annular groove 32 is a groove-shaped structure formed by cutting along the circumference of the decorative panel 3. For the scheme where the decorative panel 3 is formed by a plate with a smaller thickness, the annular groove 32 is formed by bending the circumference of the decorative panel 3 toward the side close to the insulation board 1, then bending toward the center of the decorative panel 3, and then bending toward the outside of the decorative panel 3.

[0081] Of course, in other implementation examples, the sealing ring 321 can be omitted, and multiple sealing strips can be provided in the annular groove 32 along the circumference of the decorative panel 3. That is, the sealing strips can be used to replace the sealing ring 321, so as to achieve the same effect of increasing the sealing between two adjacent decorative panels 3.

[0082] In other embodiments, the reinforcement 2 can also be provided on the outer end face of the insulation plate 1, and the design of the receiving hole 11 is eliminated.
