Detailed implementation manners

[0026] The present invention will be further described below with reference to the embodiments shown in the drawings.

[0027] Embodiment 1: As shown in Appendix Figure 1 and Appendix Figure 2 shown, the metal roof 1 is composed of a plurality of metal plates spliced together, and a standing edge 2 of the metal roof 1 is formed at the splicing position of adjacent metal plates. The structure of the edge 2 includes a standing seam mounting member 3 perpendicular to the metal roof 1, a first folded edge formed by folding the edge of one metal plate, and a second folded edge formed by folding the edge of another metal plate. The first folded edge extends upward along one side of the standing seam mounting member 3 to the top of the standing seam mounting member 3 and covers the top of the standing seam mounting member 3, while the second folded edge extends upward along the other side of the standing seam mounting member 3 to the top of the standing seam mounting member 3 and covers a partial first folded edge outside the top of the standing seam mounting member 3. Among them, the standing seam mounting member 3 is often not arranged longitudinally along the length directions of the first folded edge and the second folded edge (i.e., perpendicular to the drawing plane), but is arranged at intervals.

[0028] For the metal roof 1 with the above structure, the following hanging structure for installing a photovoltaic tile on the metal roof is designed to install the photovoltaic tile 15 on the metal roof 1 with an edge 2.

[0029] The hanging structure for installing a photovoltaic tile on the metal roof includes a component frame 4 and a clip. As shown in Appendix Figure 2 , 3As shown, the component frame 4 is connected to the photovoltaic tile 14 and fixed at the edge of the photovoltaic tile 14. It includes at least a fixing part 6 and a connecting part 7. The fixing part 6 is used to be fixed at the edge of the photovoltaic tile 14 and includes a glass groove 9 for embedding the edge of the photovoltaic tile 14. The inner wall of the glass groove 9 is an uneven curved surface. The connecting part 7 is connected to one side of the fixing part 6 (the upward side) and is provided with a first screw hole. The clip is clamped on the edge 2 and connected to the component frame 4 through a limiting part, so as to limit the photovoltaic tile 14. A second screw hole is provided on the clip corresponding to the first screw hole. The limiting part includes a mounting screw 5. The mounting screw 5 is arranged in the first screw hole and the second screw hole, so that the connecting part 7 is connected to the clip and the edge 2 of the metal roof 1. When the photovoltaic tile 14 is installed on the metal roof 1, the end of the screw rod of the mounting screw 5 abuts against the edge 2 of the metal roof 1. Further, the edge 2 of the metal roof 1 forms a depression under the abutting action of the mounting screw 5, and the end of the screw rod of the mounting screw 5 fits tightly with the depression.

[0030] The connecting part 7 includes a connecting plate 10 and a baffle 11. One side of the connecting plate 10 is connected to the fixing part 6, and the baffle 11 is arranged on the other side of the connecting plate 10. The thickness of the middle part of the connecting plate 10 is greater than that of its edge, so that a thickened part is formed in the middle part of the connecting plate 10, and the first screw hole is opened in the thickened part. In addition, the component frame 4 further includes a supporting part 8 connected to the other side of the fixing part 6 (the downward side) and supported on the metal roof 1. The supporting part 8 includes a supporting plate 12 connected to the fixing part 6 and located between the fixing part 6 and the metal roof 1, and a bottom plate 13 connected to the supporting plate 12 and directly or indirectly placed on the metal roof 1. The supporting plate 12, the bottom plate 13 of the glass groove 9, and the connecting plate 10 are coplanar. The component frame 4 and the photovoltaic tile 14 (i.e., the glass component) form an integral body, and the component frame 4 is fixed to the photovoltaic tile 14 by structural adhesive or other means.

[0031] In this embodiment, the clip adopts a metal fixture 22. The metal fixture 22 includes a first clamping jaw 16, a second clamping jaw 17, and a connecting bolt 15 for connecting the first clamping jaw 16 and the second clamping jaw 17. Since the edge 2 of the metal roof 1 has a top with a circular cross-section, the metal fixture 22 also has a clamping part with a circular cross-section matching the top.

[0032] The prerequisite for applying the hanging structure when the above photovoltaic tiles are installed on a metal roof is that the installation of the metal roof 1 with the upright lock edge 2 has been completed. First, install metal clamps 22 on the lock edge 2 of the metal roof 1. The metal clamps 22 can be arranged at intervals or can be set continuously. The metal clamps 22 are clamped on the lock edge 2 and cannot move in the direction perpendicular to the metal roof 1. Then, place the photovoltaic tile 14 with the component frame 4 on the metal roof 1 between the two lock edges 2, install the installation screws 5 into the first screw hole and the second screw hole. The end of the screw rod of the installation screw 5 is squeezed into the side of the lock edge 2 to form a depression, so that the photovoltaic tile 14 is tightly fixed to the metal roof 1. All the photovoltaic tiles 14 are laid in the same way. The photovoltaic tiles 14 are attached to the surface of the metal roof 1, which can not only keep the same overall appearance form as the original metal roof 1, but also play a decorative effect on the original metal roof 1, making the appearance of the metal roof 1 more beautiful.

[0033] Since there is a support part 8 in the component frame 4, there is a certain gap between the photovoltaic tile 14 and the surface of the metal roof 1, forming a heat dissipation and ventilation channel on the back of the photovoltaic tile 14, which helps the heat dissipation and ventilation of the metal roof 1 and the photovoltaic tile 14, and also plays a positive role in the heat insulation of the metal roof 1.

[0034] Embodiment 2: As shown in the appendix Figure 4 、 5 shown, the hanging structure when the photovoltaic tile is installed on the metal roof includes a component frame 4 and a clip. The component frame 4 only includes a fixing part 6 fixed to the edge of the photovoltaic tile 14, and the structure is the same as the fixing part 6 in Embodiment 1. The clip uses a metal clamp 22, and the difference between it and the metal clamp 22 in Embodiment 1 is that: the second screw hole is not opened on the clip (i.e., the metal clamp 22), but the clip has a pressing part. Specifically, the bottom of the first clamping jaw 16 and the second clamping jaw 17 in the metal clamp 22 forms the pressing part. Then, the clip (i.e., the metal clamp 22) indirectly presses the fixing part 6 of the component frame 4 through its pressing part to limit the photovoltaic tile 14. An upper side rubber strip 19 located on the upper side of the photovoltaic tile 14 is arranged between the pressing part of the clip and the fixing part 6, and a single-sided sticker 21 or a double-sided sticker is arranged between the fixing part 6 and the metal roof 1. A notch is opened in the pressing part of the clip, and a part of the upper side rubber strip 19 is embedded in the notch. The length of the upper side rubber strip 19 is the same as the length of the metal clamp 22 in this direction.

[0035] When implementing the hanging structure for installing the photovoltaic tile on the metal roof, first place the photovoltaic tile 14 with the component frame 4 on the metal roof 1 between the two locking edges 2. A common single-sided sticker 21 is attached to the back of the component frame 4. One side of the single-sided sticker 21 has adhesiveness and is stuck to the component frame 4, while the other side has no adhesiveness. The single-sided sticker 21 is made of flexible foam material, and the single-sided sticker 21 can also be replaced with a double-sided sticker with adhesiveness on both sides. Install each metal fixture 22, use the connecting bolt 15 to connect the first jaw 16 and the second jaw 17 and tighten the connecting bolt 15 to firmly clamp the metal fixture 22 on the locking edge 2, and the upper side rubber strip 19 embedded in its notch presses tightly against the component frame 4, so that the photovoltaic tile 14 is firmly fixed on the metal roof 1.

[0036] Embodiment 3: As shown in the appendix Figure 6 The difference between this embodiment and Embodiment 2 is that: the pressing part of the metal fixture 22 does not embed the upper side rubber strip 19, but directly presses the fixing part 6 of the component frame 4 to limit the photovoltaic tile 14. And a lower side rubber strip 20 located under the photovoltaic tile 14 is arranged between the fixing part 6 of the component frame 4 and the metal roof 1. A notch can be opened below the fixing part 6 of the component frame 4, and a part of the lower side rubber strip 20 can be embedded in the notch.

[0037] Embodiment 4: As shown in the appendix Figure 7 、 8 、9, the difference between this embodiment and Embodiment 1 is that: the clip is a locking edge buckle 18, and a second screw hole corresponding to the first screw hole on the component frame 4 is opened on the locking edge buckle 18. The locking edge buckle 18 is made of metal (it can be the same material as the metal roof 1 or a different material), and it is integrally formed and has a certain elasticity, and can be firmly clamped on the locking edge 2. The locking edge buckle 18 is usually arranged along the length direction of the locking edge 2 (perpendicular to the drawing plane), and its length is the same as the length of the locking edge 2. On the one hand, the locking edge buckle 18 is tightly buckled with the upright locking edge 2, and on the other hand, it can also be fixedly strengthened on the upright locking edge mounting member 3 through the connecting bolt 15. Because the upright locking edge mounting member 3 is not arranged in a continuous length, but is arranged at intervals, and the locking edge buckle 18 is of continuous length, so the bolt connection between the locking edge buckle 18 and the upright locking edge mounting member 3 can be set corresponding to each upright locking edge mounting member 3, or can only be set corresponding to the upright locking edge mounting member 3 at the end position of the continuous locking edge buckle 18.

[0038] The photovoltaic tile 14 passes through the locking edge buckle 18 with the installation screw 5 and is pushed into the surface of the locking edge 2, squeezing a depression on the surface layer of the locking edge 2, so that the installation screw 5 is firmly fixed to the metal roof 1. At the same time, because the installation screw 5 penetrates the locking edge buckle 18, the connection reliability between the photovoltaic tile 14 and the metal roof 1 is further enhanced.

[0039] The above-mentioned solutions are easy to install. Compared with the traditional method of installing photovoltaic modules by erecting brackets on the surface of the metal roof 1, this solution is easier to install, consumes less materials, and also improves the consistency of the appearance of the photovoltaic modules and the metal roof 11 on the metal roof 1, thus enhancing the appearance effect of the building roof.

[0040] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it is not intended to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
