In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present invention, "plurality" means two or more, unless otherwise clearly and specifically limited.

Referring to Figure 1, a photovoltaic module installation structure includes: a first step portion 12; a dovetail groove 11 opened on the inside of the top of the first step 12; a clamping portion 13 extending on the first step 12 downward, and the clamping portion 13 is recessed toward the inside of the first step portion 12; the second step portion 14 extends downward from the bottom of the clamping portion 13.

When in use, the dovetail groove 11 is used to accommodate bolts, and the unique shape structure of the dovetail groove 11 uses less material than the T-shaped groove. In comparison, the cost of the material is reduced, but compared to the T-shaped groove In the design of the groove, due to the reduced material of the dovetail groove 11 and the narrow inner opening, its strength may be affected. In order to avoid this effect, a clamping part 13 is extended below the first step part 12. By clamping The cooperation between the clamping part 13 and the clamping part 2 enables the clamping relationship between the clamping part 13 and the clamping part 2 to share part of the pulling force for the dovetail groove 11 when the entire photovoltaic module installation structure is acted upon by an external force, so that the dovetail groove 11 can It is not prone to deformation when subjected to external impact.

In order to facilitate processing, the two chamfers inside the dovetail groove 11 are set as rounded corners, which can be quickly formed during the processing without the need for fine processing to right angles, and can provide a certain amount of space for the setting of bolts. Even when the bolt is impacted by an external force, there is still a certain buffer space, so that the plate body of the dovetail groove 11 will not be directly pulled.

In another embodiment, the present invention also provides a color steel tile, including the above-mentioned photovoltaic module installation structure, specifically:

A clamping member 2 is clamped on the inner side of the photovoltaic module installation structure. The clamping member 2 includes a support portion 21 that fits inside the first step portion 12 and is clamped with the clamping portion 13 . The fitting part 22 and the fixing part 23 extending downward from the fitting part 22. During use, the arched support part 21 directly fits the inside of the first step part 12 and can share the burden of the first step part 12. Part of the pressure comes from the photovoltaic module. In other embodiments, the support part 21 can be supported by fitting and supporting on both sides, or directly raised to the bottom of the dovetail groove 11 for support, and the downwardly extending fitting part 22. The shape is adapted to the clamping part 13 and can be engaged with the clamping part 13. In this embodiment, the shape of the clamping part 13 is arc-shaped.

In the embodiment, the clamping part 13 can also be L-shaped, C-shaped, etc., and the fitting part 22 can be adapted thereto. After the fitting part 22 cooperates with the clamping part 13, it can tightly bind the entire photovoltaic module installation structure. , when the photovoltaic module installation structure is pushed upward by an external force, the clamping part 13 can be tightly pressed by the matching part 22 so that it cannot be lifted off, and the fixing part 23 can fix the entire clamping member 2 to the outside. The installation structure makes the entire clamping member 2 more stable.
