[0032] Referring to the accompanying drawings, the present invention provides a conveniently deployed thermal insulation and fireproof photovoltaic exterior wall system, comprising an exterior wall module, wherein the exterior wall module is provided with a frame, wherein the frame is formed by connecting side profile frame strips 1, top profile frame strips 2 and bottom profile frame strips 3 on both sides, wherein the height of the exterior wall module matches the floor height of the building, and each floor only needs one exterior wall module in the height direction, and the exterior wall modules on the same floor are arranged in sequence adjacent to each other on the left and right sides.

[0033] The exterior wall module is divided into a first exterior wall module and a second exterior wall module according to whether a window is provided. The first exterior wall module is not provided with a window, and the first exterior wall module is provided with a panel located on the outside and an inner thermal insulation fire wall body. The inner thermal insulation fire wall body is connected and fixed to the frame, and the panel is separated from the inner thermal insulation fire wall body and connected to the front end of the frame alone. As shown in the figure, there is a gap 64 between the inner thermal insulation fire wall body and the panel surface which is much larger than the thickness of the panel. The panel can be independently disassembled and assembled relative to the thermal insulation fire wall body, and replacement is convenient. At least part of the first exterior wall module is a photovoltaic exterior wall module, and part of it can also be a decorative exterior wall module (for example, located on a decorative facade or on a sun-proof side, and only the installation of the panel is different between the two, while the installation structure of the thermal insulation fire wall body is the same, thereby improving standardization and assembly efficiency).

[0034] The panel of the photovoltaic exterior wall module includes a photovoltaic panel 4, and the panel of the decorative exterior wall module is a decorative panel 5. In this embodiment, the decorative panel is made of aluminum.

[0035] The inner heat-insulating fire wall body is composed of a heat-insulating core wall 61, an inner fireproof board 62 and an outer fireproof board 63, wherein the inner fireproof board 62 is connected to the rear side wall of the frame by screws, and the outer fireproof board 63 is connected to the inner side wall of the frame by angle code 631 and screws. The heat-insulating core wall 61 is sandwiched between the inner fireproof board 62 and the outer fireproof board 63. The fireproof board can be a 10mm calcium silicate board, and the heat-insulating core wall can be a 100mm thick fireproof rock wool with a bulk density of 100kg / m³.

[0036] Furthermore, the present invention also provides a fireproof structure in the frame. The side profile frame strip 1 includes a main cavity structure 11 located on the inner side and a groove 12 located on the outer side and opening to the side. The top profile frame strip 2 and the bottom profile frame strip 3 respectively provide main cavities 21 and 31. The inner side walls of the main cavities 11, 21 and 31 are located on the inner side walls of the frame and serve as the inner side walls of the frame. The rear side walls of the main cavities 11, 21 and 31, the rear side groove walls of the groove 12 and the rear side walls of the main cavities 21 and 31 constitute the rear side walls of the frame. The front side walls of the main cavities 11, 21 and 31, the front side groove walls of the groove 12 and the front side walls of the main cavities 21 and 31 constitute the front side walls of the frame.

In this way, fire protection of the vertical joints between the frames is also achieved.

[0038] The vertical joints are provided with fireproof glue 71 between the rear ends of the outer grooves 12 of the adjacent side profile frame strips, and the joints between the adjacent panels are sealed with sealant 72. Fillers are provided on the backs of the fireproof glue 71 and the sealant 72 to support the fireproof glue 71 and the sealant 72, and the fillers can be foam rods.

[0039] The top profile frame strip 2 and the bottom profile frame strip 3 are respectively provided with corresponding convex tenon configurations 22 and groove configurations 32 along the length direction, so that the upper and lower adjacent external wall modules can be plugged and connected; thus, the main cavity 311 on both sides of the groove configuration 32 of the bottom profile frame strip 3 is filled with fireproof glue 65, thereby ensuring the lower positioning and fixation of the external wall plate, and at the same time, improving the fireproof ability of the joint between adjacent layers (the inner side of the joint is the building's crossbeam 100 or the ground plaster 200 or the inner fireproof shielding plate 201 fixed on the plaster). Furthermore, the front side joint between the upper and lower adjacent external wall modules is sealed with sealant 73, and a filler is provided on the back of the sealant 72 to support the sealant 73.

[0040] The upper part of the side profile frame strip 1 of the exterior wall module is cut with a hanging groove 13 that opens to the rear side and is suitable for hanging at the position corresponding to the building cross beam 100. The hanging groove 13 includes an introduction inclined groove section 131 and a hanging groove section 132. The side profile frame strip is provided with a closed cutting surface and a hanging member 130 that matches the introduction inclined groove section and the hanging groove section. The hanging member 130 has an opening, an inclined groove section and a hanging groove section to the rear side, which are suitable for closing the cutting surface and hanging. The cross beam 100 is provided with an embedded part 101, and the hanging fixing part 103 is fixed on the embedded part 101 through a T-shaped connecting part 102. The hanging fixing part 103 can be a horizontal steel rod. The upper part of the exterior wall plate is connected by hanging, and the lower part is connected by plugging, so as to utilize the frame fireproof structure to provide better fireproof ability and facilitate disassembly and assembly.

[0041] In this embodiment, the decorative panel 5 is made of aluminum alloy plate, with hems set at the edges, the notch of the groove 12 of the side profile frame strip 1 is provided with a backward hem 121, and the two side hems of the decorative panel 5 are connected to the hems 121 of the notch, and the connection method can be connected by rivets 122; the front ends of the outer sides of the top profile frame strip 2 and the bottom profile frame strip 3 are provided with steps that match the upper and lower side hems of the decorative panel 5, and the upper and lower side hems of the decorative panel 5 are connected to the step surface by rivets 122. The photovoltaic panel 4 is bonded to the front of the side profile frame strip 1, the top profile frame strip 2 and the bottom profile frame strip 3.

[0042] The second exterior wall module is provided with a window module 300, which is connected to the rear side of the frame, and the front side of the frame is connected with a decorative corner profile strip 8. One side of the corner profile strip 8 is provided with a backward folded edge 81 and connected to the notch folded edge 121 through a rivet 124, and the other side is provided with a folded edge 82 toward the side profile frame strip 1 and connected to the inner side wall of the side profile frame strip 1 through a connector 83, and the connector 83 can be an angle code.
