The roof panel has a plurality of parallel and mutually spaced peak structures, the solar photovoltaic panel is placed on the peak structures, and the fixing clamp is fixedly installed on the peak structure and close to the side of the solar photovoltaic panel. One side of the upper end of the fixing clamp also extends toward the adjacent solar photovoltaic panel and forms a frame portion that presses the solar photovoltaic panel from top to bottom.

[0006] Furthermore, the fixing fixture is composed of a left half of the fixture and a right half of the fixture, the left half of the fixture includes an upper top plate, a middle left vertical plate and a lower left clamping plate which are integrally formed from top to bottom, the lateral side of the upper top plate also extends outward to form the frame portion, the bottom of the lower left clamping plate is a hook-shaped structure facing inward, and the right half of the fixture includes a middle right vertical plate and a lower right clamping plate which are integrally formed from top to bottom, the bottom of the lower right clamping plate is a hook-shaped structure facing inward, when the left half of the fixture and the right half of the fixture are assembled and fixed, the lower left clamping plate and the lower right clamping plate form an installation clamping groove for clamping the wave crest structure.

[0007] Furthermore, a gasket is provided on the lower surface of the frame portion.

[0008] Furthermore, the corresponding positions of the middle left vertical plate and the middle right vertical plate are processed with transversely penetrating bolt holes, and the left half of the fixture and the right half of the fixture are fixedly assembled by mounting bolts matching the bolt holes.

[0009] More preferably, the upper position of the middle left vertical plate is also provided with a longitudinally arranged convex strip, and a longitudinal groove is formed in the inner boundary area between the middle left vertical plate and the upper top plate, and the top end of the middle right vertical plate also extends to the left and forms a longitudinal protrusion that can extend into the longitudinal groove.

[0010] More preferably, the outer wall surfaces on both sides of the crest structure are concave to form longitudinal fixing grooves, and when the fixing clamp is fixedly installed on the crest structure, the hook-shaped structures at the bottom ends of the lower left clamp and the lower right clamp are completely stuck in the fixing grooves.

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0024] In the following implementation manners or examples, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0025] In order to save materials and improve the strength and wind resistance of the photovoltaic building integrated roof system, the present invention provides a high-performance photovoltaic building integrated roof installation structure. Figure 1 、 Figure 2 and Figure 7 As shown in the figure, it includes a roof panel 2, a solar photovoltaic panel 3 and a fixing fixture 1. The roof panel 2 has a plurality of parallel and mutually spaced peak structures 21. The solar photovoltaic panel 3 is placed on the peak structure 21. The fixing fixture 1 is fixedly installed on the peak structure 21 and is close to the side of the solar photovoltaic panel 3. One side of the upper end of the fixing fixture 1 also extends toward the adjacent solar photovoltaic panel 3 and forms a frame portion 116 that presses the solar photovoltaic panel 3 from top to bottom.

[0026] In some specific embodiments, please refer to Figures 2 to 6As shown, the fixing fixture 1 is composed of a left fixture half 11 and a right fixture half 12. The left fixture half 11 includes an upper top plate 111, a middle left vertical plate 112, and a lower left clamping plate 113, which are integrally formed from top to bottom. A lateral side of the upper top plate 111 also extends outward to form the frame portion 116. The bottom of the lower left clamping plate 113 is an inwardly hooked structure. The right fixture half 12 includes a middle right vertical plate 121 and a lower right clamping plate 122, which are integrally formed from top to bottom. The bottom of the lower right clamping plate 122 is an inwardly hooked structure. When the left fixture half 11 and the right fixture half 12 are assembled and fixed, the lower left clamping plate 113 and the lower right clamping plate 122 form a mounting groove for clamping the crest structure 21. The shape of the mounting groove here is adapted to the upper region of the crest structure 21 to achieve a stable installation.

[0027] For more specific implementation, please refer to Figure 1 As shown, a gasket is further provided on the lower surface of the frame portion 116. The gasket may have a certain elasticity, which not only facilitates installation but also prevents the rigid frame portion 116 from being over-pressed during the pressing process of the solar photovoltaic panel 3 due to dimensional errors, thereby preventing the solar photovoltaic panel 3 from being damaged.

[0028] For more specific implementation, please refer to Figure 2 As shown in FIG. 1 , horizontally extending bolt holes 13 are machined into corresponding positions of the middle left vertical plate 112 and the middle right vertical plate 121. Mounting bolts 14 that match these bolt holes 13 secure the left and right halves 11, 12 of the fixture. Tightening the mounting bolts 14 compresses and secures the left and right halves 11, 12, thereby ensuring a stable mounting of the fixture 1 and the crest structure 21.

[0029] For further specific implementation, please refer to Figure 2As shown in the figures, the upper position of the middle left vertical plate 112 is further provided with a longitudinally arranged convex strip 114, and a longitudinal groove 115 is formed in the inner boundary area between the middle left vertical plate 112 and the upper top plate 111. The top end of the middle right vertical plate 121 also extends to the left and forms a longitudinal protrusion 123 that can extend into the longitudinal groove 115. The ridges 114 and longitudinal projections 123 are formed by protruding from the middle left vertical plate 112 and the middle right vertical plate 121. By engaging the longitudinal projections 123 with the longitudinal grooves 115, not only can the left and right halves 11 and 12 of the clamp be pre-assembled, but more importantly, as the mounting bolts 14 are gradually tightened, the contact point between the longitudinal projections 123 and the longitudinal grooves 115 serves as a fulcrum, causing the lower left clamping plate 113 and the lower right clamping plate 122 to move closer together, clamping the sidewalls of the crest structure 21. This allows the hook-shaped structure at the bottom to engage with the fixing grooves 22 of the crest structure 21. The longitudinal projections further enhance the strength of the mounting structure, providing greater pressure against the photovoltaic panel.

[0030] For further specific implementation, please refer to Figure 2 As shown in FIG. 1 , the outer wall surfaces on both sides of the crest structure 21 are also concave to form longitudinal fixing grooves 22, and when the fixing fixture 1 is fixedly installed on the crest structure 21, the hook-shaped structures at the bottom ends of the lower left clamp 113 and the lower right clamp 122 are completely stuck in the fixing grooves 22. More preferably, the angle between the hook-shaped structures at the bottom ends of the lower left clamp 113 and the lower right clamp 122 is a right angle or an obtuse angle. More preferably, the shape and position of the fixing grooves 22 meet the following conditions: when the frame portion 116 of the fixing fixture 1 just contacts the solar photovoltaic panel 3 placed on the crest structure 21, the hook-shaped structures at the bottom ends of the lower left clamp 113 and the lower right clamp 122 just or partially extend into the fixing grooves 22. After the hook-shaped structure is fully inserted into the fixing groove 22, the cooperation between the hook-shaped structure and the fixing groove 22 provides a clamping force on the solar photovoltaic panel 3. At the same time, compared with the traditional vertical bolt structure clamping method, it can also improve its anti-loosening effect. In addition, the position of the fixing groove 22 and the transition angle between it and the outer wall of the crest structure 21 should be appropriate, not too large (i.e., a large obtuse angle) or too small (i.e., a small acute angle). This allows the hook-shaped structure to be relatively smoothly inserted into the fixing groove 22 during the tightening process of the mounting bolt 14, but not too easily dislodged, thereby causing the clamping force provided to the solar photovoltaic panel 3 to be insufficient or even impossible to clamp. Generally, it is appropriate to float 5 to 10 degrees around the right angle.

[0031] For further specific implementation, please refer to Figure 2 As shown in FIG. 1 , there are several bolt holes 13 , and two or more bolt holes may be provided.

[0032] In some specific embodiments, please refer to Figure 1 As shown, the height of the interlocking connection portion of two adjacent roof panels 2 is higher than the crest structure 21, and the solar photovoltaic panel 3 is installed just between the two adjacent interlocking connection portions, further improving its wind resistance.

[0033] The above embodiments may be implemented individually or in any combination of two or more.

[0034] The above implementation is described in more detail below with reference to specific examples.

[0035] Example 1:

[0036] In order to save materials and improve the strength and wind resistance of the photovoltaic building integrated roof system, the present invention provides a high-performance photovoltaic building integrated roof installation structure. Figure 1 、 Figure 2 and Figure 7 As shown in the figure, it includes a roof panel 2, a solar photovoltaic panel 3 and a fixing fixture 1. The roof panel 2 has a plurality of parallel and mutually spaced peak structures 21. The solar photovoltaic panel 3 is placed on the peak structure 21. The fixing fixture 1 is fixedly installed on the peak structure 21 and close to the side of the solar photovoltaic panel 3. One side of the upper end of the fixing fixture 1 also extends toward the adjacent solar photovoltaic panel 3, and forms a frame portion 116 that presses the solar photovoltaic panel 3 from top to bottom.

[0037] Please see again Figures 2 to 6 As shown, the fixing fixture 1 is composed of a left half 11 and a right half 12. The left half 11 includes an upper top plate 111, a middle left vertical plate 112, and a lower left clamping plate 113, which are integrally formed from top to bottom. A lateral side of the upper top plate 111 also extends outward to form a frame portion 116. The bottom of the lower left clamping plate 113 is a hook-shaped structure facing inward. The right half 12 includes a middle right vertical plate 121 and a lower right clamping plate 122, which are integrally formed from top to bottom. The bottom of the lower right clamping plate 122 is a hook-shaped structure facing inward. When the left half 11 and the right half 12 are assembled and fixed, the lower left clamping plate 113 and the lower right clamping plate 122 form a mounting groove for clamping the crest structure 21. The shape of the mounting groove here is adapted to the upper area of ​​the crest structure 21 to achieve a stable installation.

[0038] Please see again Figure 1 As shown, a gasket is further provided on the lower surface of the frame portion 116. The gasket may have a certain elasticity, which not only facilitates installation but also prevents the rigid frame portion 116 from being over-pressed during the compression of the solar photovoltaic panel 3 due to dimensional errors, thereby preventing the solar photovoltaic panel 3 from being damaged.

[0039] Please see again Figure 2 As shown in FIG. 1 , horizontal bolt holes 13 are formed in corresponding positions of the middle left vertical plate 112 and the middle right vertical plate 121. Mounting bolts 14 that match the bolt holes 13 secure the left and right halves 11 and 12 of the fixture. Tightening the mounting bolts 14 compresses and secures the left and right halves 11 and 12, thereby ensuring a stable mounting of the fixture 1 and the crest structure 21.

[0040] Please see again Figure 2 As shown in the figures, a longitudinally arranged ridge 114 is provided at the upper position of the middle left vertical plate 112, and a longitudinal groove 115 is formed at the inner boundary area between the middle left vertical plate 112 and the upper top plate 111. The top end of the middle right vertical plate 121 also extends to the left and forms a longitudinal protrusion 123 that can extend into the longitudinal groove 115. The convex strip 114 and the longitudinal protrusion 123 here are specifically obtained by protruding from the middle left vertical plate 112 and the middle right vertical plate 121. By snapping the longitudinal protrusion 123 into the longitudinal groove 115, not only can the pre-installation of the left half piece 11 of the clamp and the right half piece 12 of the clamp be achieved, but more importantly, when the mounting bolt 14 is gradually tightened, with the contact part of the longitudinal protrusion 123 and the longitudinal groove 115 as the fulcrum, the lower left clamping plate 113 and the lower right clamping plate 122 will be further relatively close to each other and clamp the side wall of the crest structure 21, so that the hook-shaped structure at the bottom is snapped into the fixing groove 22 of the crest structure 21.

[0041] Please see again Figure 2As shown in FIG. 1 , the outer walls of both sides of the wave crest structure 21 are further concave to form longitudinal fixing grooves 22. When the fixing fixture 1 is fixedly mounted on the wave crest structure 21, the hook-shaped structures at the bottom ends of the lower left clamping plate 113 and the lower right clamping plate 122 are fully engaged in the fixing grooves 22. The angle between the hook-shaped structures at the bottom ends of the lower left clamping plate 113 and the lower right clamping plate 122 is a right angle or an obtuse angle. The shape and position of the fixing grooves 22 are such that when the frame portion 116 of the fixing fixture 1 just contacts the solar photovoltaic panel 3 placed on the wave crest structure 21, the hook-shaped structures at the bottom ends of the lower left clamping plate 113 and the lower right clamping plate 122 just or partially extend into the fixing grooves 22. After the hook-shaped structures are fully engaged in the fixing grooves 22, the cooperation between the hook-shaped structures and the fixing grooves 22 provides a clamping force on the solar photovoltaic panel 3. At the same time, compared with the traditional vertical bolt structure clamping method, the anti-loosening effect can also be improved. In addition, the position of the fixing groove 22 and the transition angle between its upper wall and the outer wall of the crest structure 21 should be appropriate, not too large (i.e., a large obtuse angle) or too small (i.e., a small acute angle), so that during the tightening process of the installation bolt 14, the hook-shaped structure can be relatively smoothly inserted into the fixing groove 22, but it should not be too easy to fall out, so that the clamping force provided to the solar photovoltaic panel 3 is insufficient or even impossible to clamp. It is generally appropriate to float 5 to 15 degrees around the right angle. In addition, the outer wall of the crest structure 21 can be appropriately tilted outward relative to its top plane to facilitate the bottom end of the fixing clamp 1 to be pre-tightened and inserted into the fixing groove.

[0042] Please see again Figure 2 As shown in FIG. 1 , several bolt holes 13 are provided, and two or more bolt holes may be provided.

[0043] Please see again Figure 1 As shown, the height of the interlocking connection portion of two adjacent roof panels 2 is higher than the crest structure 21, and the solar photovoltaic panel 3 is installed just between the two adjacent interlocking connection portions, further improving its wind resistance and the like.

[0044] The above description of the embodiments is intended to facilitate understanding and use of the invention by those skilled in the art. It will be apparent that those skilled in the art can readily make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the present invention is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the present invention, without departing from the scope of the present invention, should be within the scope of protection of the present invention.
