Then, the installation plate and photovoltaic glass are placed inside the square frame formed by multiple horizontally and vertically distributed square steel pipes. Finally, a sealing frame is used to limit and fix the photovoltaic glass. Although the existing installation has a stable structure, it uses a large number of metal frame profiles, resulting in high installation costs and large installation workloads.

[0029] The following combines with the attached drawings to illustrate the specific implementation manner of this embodiment.

[0030] A composite photovoltaic thermal insulation wall panel installation structure, referring to Figure 1 and Figure 2 , includes a main keel 1, expansion bolts 7, angle brackets 3, keels 4 and a bonding layer 5. The main keel 1 is fixed on the walls on the upper and lower sides of the photovoltaic array 6 through the expansion bolts 7. A plurality of angle brackets 3 are evenly distributed on the main keel 1. The photovoltaic panels 61 are fixedly installed below the angle brackets 3 through screws 8. A bonding layer is provided between the photovoltaic panels 61 and the wall;

[0031] The angle bracket 3 includes a vertical mounting plate 32 and a horizontal mounting plate 31. A screw hole for the expansion bolt 7 to pass through is provided on the vertical mounting plate 32, and a screw hole for the screw 8 to pass through is provided on the horizontal mounting plate 31. The expansion bolt 7 passes through the screw hole provided on the vertical mounting plate 32 to fix the angle bracket 3 on the wall, and the screw 8 passes through the screw hole provided on the horizontal mounting plate 31 to fix the angle bracket 3 on the photovoltaic panel 61. The thermal insulation board is integrally bonded to the photovoltaic panel, and the whole depends on the fixation of the angle bracket and the bonding of the mortar.

[0032] Since the photovoltaic building materials are composed of the photovoltaic array 6, and the photovoltaic array 6 is composed of a plurality of photovoltaic panels 61 spliced together, there are inevitably horizontal gaps 62 in the direct pressing of the photovoltaic panels 61. There is a horizontal gap 62 between adjacent photovoltaic panels 61 along the vertical direction of the wall. Building sealant can be applied between the horizontal gaps 62 to prevent rainwater from entering the horizontal gaps 62.

[0033] Bonding layers are provided on the upper and lower sides of the horizontal gap 62 and between the photovoltaic panel 61 and the wall. There is a spacing for the installation of the keel 4 between the bonding layers. The spacing between the bonding layers is greater than the height of the vertical mounting plate 32 of the keel 4 to ensure that the keel 4 does not interfere with the bonding layer. After the keel 4 and the bonding layer are set, a bonded and anchored installation structure is formed, which can ensure the stability of the installation.

[0034] A leveling layer 91 is provided on the wall. The leveling layer 91 can adopt existing waterproof materials to prevent rainwater from penetrating into the wall 9.

[0035] The thermal insulation board is provided with a wire passing groove 2. The wire passing groove 2 is a rectangular groove opened horizontally along the photovoltaic panel 61. The wire passing groove 2 is for wires to pass through, and a wire box and a plug can be arranged in the wire passing groove 2 for the transmission of current between the photovoltaic panels 61.

[0036] The installation process of the photovoltaic panel 61 is as follows:

[0037] The keel 4 is anchored on the wall surface 9 by passing the expansion bolt 7 through the leveling layer 91. The keel is arranged on the upper and lower sides of a plurality of photovoltaic panels 61. One keel 1 can correspond to a plurality of photovoltaic panels 61. The vertical mounting plate 32 of the angle code 3 is mounted on the keel 1 by bolts. After the fastener 4 at the end of the angle code 3 is snapped into the stepped groove 11, the fastener 4 drives the photovoltaic plate towards the wall surface under the action of the bolts, forming an anchoring structure. Refer to Figure 3 , an angle code 3 is arranged between adjacent photovoltaic panels 61, and at the same time, the stepped grooves 11 formed by the upper and lower adjacent photovoltaic panels 61 are buckled by the fasteners 4 arranged at the ends of the angle codes 3. Then, sealant 12 and foam rod 13 are arranged for sealing and fixing. At the same time, a bonding layer is arranged between each photovoltaic panel 61 and the wall surface 9 by the keel 1, forming a bonding structure.

[0038] Although the specific implementation manners of the present invention have been described above in conjunction with the accompanying drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
