The structural sealant 112 is filled between the mounting groove 113 of the frame 11 and the photovoltaic laminate 10 to improve the connection strength between the frame 11 and the photovoltaic laminate 10 and improve the waterproof effect.

[0083] In some embodiments, the first sealing member 14 is detachably mounted on one side of the photovoltaic laminate 10 through the disassembly groove 111; the second sealing member 15 is detachably mounted on the other side of the frame 11 away from the first sealing member 141 through the disassembly groove 111. The first sealing member 14 can be sealed and connected with the second sealing member 15 installed on another photovoltaic tile 1 adjacent to the photovoltaic tile 1.

[0084] 8 and 9 , in some embodiments, the first snap-fit ​​protrusion 161 and the second snap-fit ​​protrusion 162 are arranged from top to bottom on a side of the first sealing member 14 close to the frame 11 ; the first snap-fit ​​protrusion 161 and the second snap-fit ​​protrusion 162 are arranged from top to bottom on a side of the second sealing member 15 close to the frame 11 .

[0085] Specifically, the first sealing member 14 is clamped in the first groove 1111 through the first clamping protrusion 161, and is clamped in the second groove 1112 through the second clamping protrusion 162, so that the first sealing member 14 can be detachably mounted on the frame 11.

[0086] The second sealing member 15 is clamped in the first groove 1111 through the first clamping protrusion 161, and is clamped in the second groove 1112 through the second clamping protrusion 162, so that the second sealing member 15 can be detachably mounted on the frame 11. When the second sealing member 15 needs to be removed from the frame 11, it is only necessary to separate the first clamping protrusion 161 from the first groove 1111, and the second clamping protrusion 162 from the second groove 1112, so that the second sealing member 15 can be separated from the frame 11. By providing the first groove 1111 and the second groove 1112, the second sealing member 15 and the frame 11 have two connection positions, which improves the connection stability between the second sealing member 15 and the frame 11, thereby improving the overlap stability between the photovoltaic tiles 1.

[0087] In some embodiments, the disassembly groove 111 can be used to detachably install the first accessory 12, the second accessory 13 or the first sealing member 14, the second sealing member 15.

The first photovoltaic tile 17 is away from the outer frame 11 of the first photovoltaic tile 18 and is overlapped with the adjacent flat tile 2 through the first accessory 12 or the second accessory 13, and the frame 11 of the first photovoltaic tile 17 close to the first photovoltaic tile 18 and the left and right side frames 11 of the first photovoltaic tile 18 are connected correspondingly through the first sealing component 14 and the second sealing component 15.

[0091] Specifically, the first accessories 12 and the second accessories 13 are respectively installed on the frame 11 on both sides of the first photovoltaic tile 17, so that the first photovoltaic tile 17 can overlap the flat tile 2 on both sides. The first sealing member 14 and the second sealing member 15 are respectively installed on the frame 11 on both sides of the second photovoltaic tile 18, so that the second photovoltaic tile 18 can overlap the photovoltaic tile 1 on both sides.

[0092] In some embodiments, the photovoltaic paving structure includes a flat tile 2, a first photovoltaic tile 17, a first photovoltaic tile 18, another first photovoltaic tile 17 and another flat tile 2 arranged in sequence from left to right.
