[0032] The technical solution of the present invention is further described below in conjunction with specific implementation methods and drawings, but this description does not limit the scope of protection claimed for the present invention.

[0033] like Figure 1 As shown, in some embodiments, the construction method of the single-point anchored exterior wall thermal insulation decoration integrated panel includes the following steps:

[0034] S1: prefabricate a thermal insulation and decoration integrated panel 1, open a groove 2.2 in the center of the thermal insulation and decoration integrated panel 1, and then open a through hole 2.1 at the bottom of the groove 2.2, and the thermal insulation and decoration integrated panel 1 is square;

[0035] S2: installing a wire mesh 5 and setting fastening holes 8 on the surface of the wall 6, wherein the fastening holes 8 pass through the wire mesh 5, so that the wire mesh 5 is embedded in the wall 6;

[0036] S3: Use the fastening member 3 to pass through the through hole 2.1 from the groove 2.2 to connect the fastening hole 8, and the depth of the fastening member 3 inserted into the fastening hole 8 can be freely adjusted; after the first thermal insulation decorative integrated board is installed, fill the space between the thermal insulation decorative integrated board 1 and the wall 6 with foam glue, and adjust the fastening member 3 to adjust the distance between the thermal insulation decorative integrated board 1 and the wall 6;

[0037] S4: Taking the first thermal insulation integrated panel as the reference, install the thermal insulation decorative integrated panels 1 in sequence around the first thermal insulation decorative integrated panel. After all the installation is completed, inject foam glue from the joint 4 between two adjacent thermal insulation decorative integrated panels 1, and adjust the flatness by adjusting the depth of the fastening piece 3 inserted into the fastening hole 8.

[0038] After the above construction method is used, the following can be obtained: Figures 2 to 6 The installation structure shown in the figure specifically comprises: a wall 6, a wire mesh 5 installed on the wall 6, and fastening holes 8 penetrating the wire mesh 5 and embedded in the wall 6; the wire mesh 5 is installed on the wall 6, and the fastening holes 8 penetrating the wire mesh 5 and embedded in the wall 6, so that the wire mesh 5 can form a whole with the wall 6 under the action of the fastening holes 8, thereby improving the integrity of the wire mesh 5 and the wall 6; a square-shaped thermal insulation decorative integrated panel 1 and a fastening member 3, the thermal insulation decorative integrated panel 1 A mounting position 2 is provided in the center, and the mounting position 2 is a groove 2.2 sunken downward from the surface of the thermal insulation decorative integrated panel 1, and a through hole 2.1 penetrating the thermal insulation decorative integrated panel 1 is provided at the bottom of the groove 2.2; during installation, the mounting position 2 is connected to the fastening hole 8 by using the fastening member 3, and the fastening member 3 can adjust the depth of the fastening member 3 inserted into the fastening hole 8; a joint 4 is formed between two adjacent thermal insulation decorative integrated panels 1, and the joint 4 is poured with foam glue. The depth adjustability of the fastening piece 3 in the fastening hole 8 and the process of pouring foam glue into the joint 4 can realize the flatness adjustment of the thermal insulation decorative integrated panel 1 after it is installed on the wall 6 surface, omitting the process of leveling the wall 6 surface, simplifying the installation process of the thermal insulation decorative integrated panel 1, and helping to reduce construction costs; at the same time, the integrity of the connection of the wire mesh 5 is utilized to ensure the integrity and stability of each thermal insulation decorative integrated panel 1 after installation. Combined with the square structure of the thermal insulation decorative integrated panel 1, the thermal insulation decorative integrated panel 1 is avoided from rotating and deforming, thereby improving the stability of the single-point anchoring installation.

[0039] In some embodiments, the spacing between two adjacent fastening holes is such that the spacing of the joints formed by installing two adjacent thermal insulation and decorative integrated panels is 0.5-1mm, for example, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, etc. As long as it can be ensured that the two adjacent thermal insulation and decorative integrated panels 1 can be installed and it is convenient to pour the foam glue after the installation, the smaller the spacing of the joints 4, the better.

[0040] like Figure 2 and Figure 3 and Figure 4The structure formed by the installation shown in the figure, in some embodiments, in the step S2, before installing the wire mesh, an adhesive layer is sprayed on the wall so that the wire mesh adheres to the wall surface. Enhance the connection stability between the wire mesh 5 and the wall 6. Specifically, during construction, cement mortar or the like is sprayed on the surface of the wall 6 to form an adhesive layer 7, so that the wire mesh 5 adheres to the surface of the wall 6, thereby improving the stability of the connection between the wire mesh and the wall 6; combined with the setting of the fastening hole 8, the wire mesh 5 is embedded in the wall 6. In some embodiments, the thickness of the adhesive layer 7 is 0.5-2cm, for example: 0.5cm, 0.8cm, 0.9cm, 1cm, 1.2cm, 1.5cm, 1.6cm, 2cm, etc. Ensure that the adhesive layer 7 has excellent adhesion to the wire mesh 5 on the wall 6 to prevent the wire mesh 5 from falling off.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the fastening hole 8 is provided with an internal thread, and the fastening member 3 is provided with an external thread that can match the internal thread of the fastening hole 8. The adjustability is enhanced, and the convenience of installation and surface flatness adjustment is improved by using threaded connection.

[0042] In some embodiments, the length of the fastening member 3 in the thermal insulation decorative integrated panel 1 is less than or equal to the length of the fastening member 3 extending into the fastening hole 8. The installation stability is ensured.

[0043] like Figure 4 and Figure 6 As shown, in some embodiments, the groove 2.2 is provided with a sealing cover 9 that can be covered to enhance the sealing performance and improve the flatness of the insulation board 1 after it is installed on the surface of the wall 6.

[0044] In some embodiments, the sealing cover 9 is plugged into the groove by a latch, for example, Figure 4 The latch structure shown may be covered on the groove by threaded connection, for example, an internal thread is provided in the groove 2.2, and a matching external thread is provided on the sealing cover 9, and the sealing is installed by screwing in the threaded connection.

[0045] In some embodiments, after the sealing cover 9 is covered on the groove 2.2, the upper surface of the groove 2.2 is flush with the surface of the thermal insulation decorative integrated board 1. This helps to enhance the flatness of the thermal insulation decorative integrated board 1 after it is installed on the wall 6, improves the installation aesthetics, enhances weather resistance, helps prevent rainwater from penetrating between the thermal insulation decorative integrated board 1 and the wall 6, and prolongs the service life of the thermal insulation board 1 after installation.

[0046] In some embodiments, the area of ​​the wire mesh is larger than the area of ​​the thermal insulation decorative integrated board, and the splicing position of two adjacent wire meshes is staggered with the splicing position of two adjacent thermal insulation decorative integrated boards. This can help enhance the effect of forming an integral body of two adjacent thermal insulation decorative integrated boards 1 and improve the stability of the thermal insulation board 1 installed on the wall 6.
