Description

Technical Field

[0002] With the continuous development of photovoltaic building integration, photovoltaic modules are increasingly applied to the outer surface of buildings to form photovoltaic roof buildings. Photovoltaic roof buildings can convert light energy into electrical energy through photovoltaic modules.

[0003] In the related art, photovoltaic modules and house structures are generally connected through metal roof panels. Since roof panels and photovoltaic modules generally need to be installed outdoors, they are often attacked by rainwater, and the joints of each roof panel will be filled with rainwater. In order to avoid water leakage at the joints of the roof panels, the edges of the roof panels are usually curled into a sleeve structure by a crimping machine before the roof panels are installed, and then the adjacent roof panels are sleeved through the sleeve structure at the edge, so that each roof panel is connected in the form of a crimped edge to prevent rainwater from penetrating into the lower layer of the roof panel from the joints of the metal roof panels.

[0004] However, the roof panels connected in a rolled-edge form are not only difficult to construct, but also have poor structural stability, resulting in weak wind-resistant ability. Summary of the invention

[0071] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] Reference Figure 1 , Figure 1 FIG. 4 shows a structural diagram of a photovoltaic roof in an embodiment of the present invention. Figure 1 As shown, the photovoltaic roof includes: a roof panel 30, a waterproof covering 40, a photovoltaic module 50 and a roof support. Among them, the upper surface of the roof panel 30 is covered with a waterproof covering 40; the roof panel 30 can be a metal plate (such as a corrugated steel plate), a plastic steel plate, etc. The technician can select a roof panel 30 of a suitable material according to the actual construction environment, and the embodiment of the present invention does not specifically limit it. Since the area to be laid when laying the roof panel 30 is usually large, it is necessary to lay the roof panel 30 on the house structure 60 by connecting multiple roof panels 30. In order to avoid water seepage at the joints between the roof panels 30 and to prevent rainwater from eroding the roof panels 30, the roof panel 30 can be covered with a waterproof covering 40; the waterproof covering 40 can be a flexible material (such as an environmentally friendly polymer waterproof material, a flexible material, etc.) or a hard plate (such as an acrylic plate, a PVC plate, etc.), or it can be a composite material formed by stacking multiple materials. The waterproof covering member 40 and the roof panel 30 may be fixed by gluing, or the waterproof covering member 40 may be heated by a heating device such as a hot air gun so as to be welded and fixed to the roof panel 30 .

[0073] The photovoltaic assembly 50 is installed on the surface of the waterproof cover 40 away from the roof panel 30. Figure 1 As shown, the photovoltaic module 50 can be installed on the upper surface of the waterproof cover 40 away from the roof panel 30, and the photovoltaic module 50 can be fixed to the waterproof cover 40 by means of adhesive (such as a backing adhesive layer covering the surface of the photovoltaic module 50 or the waterproof cover 40, structural adhesive, etc.). Among them, the photovoltaic module 50 is often called a solar panel, and the photovoltaic module 50 is usually composed of transparent materials (such as flexible polymer materials, glass, etc.) encapsulating solar cells.

[0074] The roof support is connected to the lower surface of the roof panel 30 through a fastener 90, and the waterproof cover 40 covers one end of the fastener 90 located on the upper surface of the roof panel 30. Figure 1As shown, the roof panel 30 is connected to the house structure 60 through the roof support below it. Since in the embodiment of the present invention, the roof panel 30 is covered with a waterproof cover 40, drilling holes in the roof panel 30 will not cause water leakage in the roof panel 30, so the fasteners 90 (such as self-tapping screws, rivets, etc.) that penetrate the roof panel 30 can be used to fasten the roof panel 30 to the roof support. It should be noted that in the embodiment of the present invention, the waterproof cover 40 is laid on the roof panel 30 after the roof panel 30 is connected to the roof support. Therefore, the waterproof cover 40 covers the roof panel 30 while also covering the fasteners 90 on the roof panel 30, ensuring that the through holes at the location of the fasteners 90 on the roof panel 30 will not cause water leakage in the roof panel 30.

[0075] The roof support can be connected to the roof panel 30 and can also be connected to the house structure 60 on the side of the roof support away from the roof panel 30. The connection method can be welding, clamping, riveting and nailing, etc., which are not specifically limited in the embodiment of the present invention. It should be noted that the house structure 60 can include purlins, roofs, walls and other house structures 60, which are not limited in the embodiment of the present invention.

[0076] Reference Figure 2 , Figure 2 A schematic diagram of a photovoltaic roof assembly provided by an embodiment of the present invention is shown. Figure 2 As shown, a waterproof cover 40 matches the size and shape of a roof panel 30, and the waterproof covers 40 partially overlap to improve the waterproof effect. A photovoltaic module 50 can match the width of a roof panel 30, and a panel layer 3 can be formed by connecting multiple roof panels 30, a waterproof layer 4 can be formed by multiple waterproof covers 40, a photovoltaic layer 5 can be formed by covering multiple photovoltaic modules 50 on the waterproof layer 4, and the panel layer 3 can be fixed to the house structure 60 by multiple roof supports.

[0077] Reference Figure 3 , Figure 3 FIG. 1 shows a schematic diagram of the overall structure of a photovoltaic roof assembly provided by an embodiment of the present invention. Figure 3 As shown, the panel layer 3 and the waterproof layer 4 covering the panel layer 3 (because the waterproof layer 4 is thin and is closely connected to the panel layer 3, to avoid ambiguity, Figure 3 The photovoltaic roof consisting of the waterproof layer 4 (not shown in the figure), the photovoltaic layer 5 and the roof support is installed on the house structure 60.

[0078] In summary, in an embodiment of the present invention, a photovoltaic roof is disclosed, including: a roof panel 30, a waterproof covering 40, a photovoltaic module 50 and a roof support; the upper surface of the roof panel 30 is covered with the waterproof covering 40; the photovoltaic module 50 is installed on the surface of the waterproof covering 40 away from the roof panel 30; the roof panel 30 includes a support fixing hole covered by the waterproof covering 40, and the roof support is connected to the lower surface of the roof panel 30 by a fastener 90 passing through the support fixing hole. Under normal circumstances, fixing the roof panel 30 to the roof support by means of self-tapping screws, rivets, etc., which require drilling holes on the roof panel 30, can make the roof panel 30 more stable and can significantly improve the wind-resistant performance of the roof panel 30, but this method will result in poor waterproofing of the roof panel 30. In an embodiment of the present invention, a waterproof covering member 40 covering the fasteners 90 and the surface of the roof panel 30 is provided on the roof panel 30, so that the waterproofing performance of the roof panel 30 is improved while maintaining high wind-resistant performance. In addition, since the roof panel 30 has a higher stability, roof panels 30 with larger specifications and sizes can be selected for splicing, thereby increasing the size range of the compatible photovoltaic modules 50.

[0079] Optional, see Figure 4 , Figure 4 FIG. 4 shows a side view of a first sliding support provided by an embodiment of the present invention, as shown in FIG. Figure 4 As shown, the roof support includes a first sliding support 10; the first sliding support 10 includes a base 11 and a sliding seat 12, the base 11 is slidably connected to the sliding seat 12 through a sliding window 121 located on the sliding seat 12; the base 11 is fixedly connected to the house structure 60, and the sliding seat 12 is fixedly connected to the lower surface of the roof panel 30.

[0080] Due to the influence of factors such as day and night, seasons, etc., after the photovoltaic module 50 is installed on the building, the temperature will fluctuate greatly. At the same time, due to the physical characteristics of the structure such as the roof panel 30, the effect of thermal expansion and contraction will occur. In the traditional installation scheme, the roof panel 30 is directly fixedly connected to the house structure 60 through multiple connection points. When the temperature changes, the roof panel 30 will expand or contract, and each connection point will limit the movement of the roof panel 30, causing each connection point position to bear a great force, and at the same time causing a great stress inside the roof panel 30, which is not only easy to cause the connection point to loosen, but also may cause the roof panel 30 and the photovoltaic module 50 thereon to be damaged under the action of stress. Therefore, the present invention uses a first sliding support 10 to connect the roof panel 30 with the house structure 60. When the roof panel 30 expands or contracts, the sliding seat 12 of the first sliding support 10 connected to the roof panel 30 will move relative to the base 11 fixed on the house structure 60, avoiding the stress between the components caused by the thermal expansion and contraction of the roof panel 30.

[0081] like Figure 4 As shown, the base 11 of the first sliding support 10 includes two first mounting feet 111 for connecting to the house structure 60, and the two first mounting feet 111 are directly connected by a first connecting plate 112 bent upward; the sliding seat 12 of the first sliding support 10 includes two oppositely arranged side panels 123 and a second connecting plate 122 connecting the top ends of the two side panels 123, and a sliding window 121 parallel to the first connecting plate 112 is provided on each side panel 123, and the height of the sliding window 121 is greater than the thickness of the first connecting plate 112, so the first connecting plate 112 can be placed inside the sliding windows 121 of the two side panels 123. Figure 4 The length in the middle direction z is greater than the length of the first connecting plate 112 in the middle direction z. Figure 4 The width in the middle direction z is such that the base 11 of the first sliding support 10 can be displaced in the two sliding windows 121 of the sliding seat 12 along the middle direction z. When the roof panel 30 is mounted on the sliding seat 12 and the base 11 is mounted on the house structure 60, the roof panel 30 can be displaced relative to the base 11 in the middle direction z. Figure 4 A small movement in the z direction.

[0082] In addition, refer to Figure 5 , Figure 5 FIG. 4 shows a front view of a first sliding support provided by an embodiment of the present invention, as shown in FIG. Figure 5 As shown, the two side plates 123 on the sliding seat 12 of the first sliding support 10 are connected to the base 11 of the first sliding support 10. Figure 5 There may be a gap in the direction x, so that the sliding seat 12 can move relative to the mounting surface in the direction x. Therefore, in the embodiment of the present invention, the first sliding support 10 can make the roof panel 30 expand and contract in any direction of the mounting surface without generating stress that damages the internal structure, so that the roof panel 30 can float on the first sliding support 10 in any direction of the mounting surface.

[0083] Reference Figure 6 , Figure 6 FIG. 1 shows a partial enlarged view of the installation of a first sliding support provided by an embodiment of the present invention, such as Figure 6As shown, the base 11 of the first sliding support 10 is fixedly connected to the house structure 60, and the sliding seat 12 of the first sliding support 10 is fixedly connected to the buckling protrusion 33 through the fastener 90. The waterproof cover 40 covers the upper surface of the roof panel 30 and the fastener 90 located on the roof panel 30, and the top of the waterproof cover 40 located on both sides of the buckling protrusion 33 is provided with an adhesive layer 91, and the two photovoltaic modules 50 are fixed to the waterproof cover 40 through the adhesive layer 91. It should be noted that after the waterproof cover 40 is set on the surface of the roof panel 30, the ridge formed by the waterproof cover 40, the fastener 90 and the buckling protrusion 33 can play a limiting role in the installation of the photovoltaic module 50, thereby improving the installation efficiency and installation accuracy of the photovoltaic module 50.

[0084] like Figure 6 As shown, a first nail groove 311 may be further provided on the snap-fitting protrusion 33 of the first tile rib 31, and the first nail groove 311 is parallel to the tile rib upper wall 321 of the first tile rib 31. Since the first tile rib 31 will cover the first sliding support 10 during construction, the first sliding support 10 is blocked at this time, and the position of the junction between the first sliding support 10 and the inner surface of the first tile rib 31 cannot be determined, which makes it difficult to install the fastener 90. Therefore, the above-mentioned first nail groove 311 may be provided, and the punching position of the fastener 90 may be determined by the first nail groove 311 during construction. Under the fixing effect of the first nail groove 311, the fastener 90 will not be offset on the outer surface of the first tile rib 31, which reduces the construction difficulty and improves the construction accuracy.

[0085] Optional, see Figure 7 , Figure 7 FIG. 4 shows a side view of a second sliding support provided by an embodiment of the present invention, such as Figure 7 As shown, the roof support includes a second sliding support 20; the second sliding support 20 includes a support body 21, a sliding groove 211 located on the support body 21, and a sliding sleeve 22 located in the sliding groove 211; the sliding sleeve 22 includes a cover 221 and a sleeve body 222, the diameter of the cover 221 is larger than the width of the sliding groove 211, and the diameter of the sleeve body 222 is smaller than the width of the sliding groove 211; the sleeve body 222 passes through the sliding groove 211 and is fixedly connected to the house structure 60, so that the support body 21 slides along the sliding groove 211 between the cover 221 and the house structure 60.

[0086] In the embodiment of the present invention, it is also possible to Figure 7 The second sliding support 20 shown in the figure connects the roof panel 30 to the building structure 60 in a floating manner. Figure 7As shown, the second sliding support 20 includes a support body 21, and two second mounting feet 212 are arranged on one side of the support body 21 close to the house structure 60. The two second mounting feet 212 are connected by a door-type connecting piece, and each second mounting foot 212 is provided with a sliding groove 211; the second sliding support 20 also includes a sliding sleeve 22 located in each sliding groove 211, and the cross-section of the sliding sleeve 22 is a T-shaped structure, one end of the sliding sleeve 22 is a sleeve cover 221 with a slightly larger diameter, and the other end of the sliding sleeve 22 is a sleeve body 222 with a slightly smaller diameter. When the sliding sleeve 22 is placed in the sliding groove 211, since the diameter of the sleeve cover 221 is greater than the width of the sliding groove, the sleeve cover 221 can be against the edge of the sliding groove 211, and since the height of the sleeve body 222 is greater than the thickness of the second mounting foot 212.

[0087] Reference Figure 8 , Figure 8 FIG. 4 shows a front view of a second sliding support provided by an embodiment of the present invention, as shown in FIG. Figure 8 As shown, when the sliding sleeve 22 is fixed on the house structure 60 , there is a gap between the sleeve cover 221 and the second mounting foot 212 , so that the support body 21 can slide between the house structure 60 and the sliding sleeve 22 .

[0088] Since the second sliding support 20 can only make the roof panel 30 float in one direction, installing the second sliding support 20 while installing the first sliding support 10 can increase the stability of the roof panel 30.

[0089] Optional, such as Figure 1 As shown, the roof panel 30 may be a corrugated structure (such as a corrugated steel plate), and a panel tile rib of the roof panel 30 is formed at a wave crest of the corrugated structure, and the panel tile rib includes a first tile rib 31 located at both ends of the roof panel 30, and a second tile rib 32 located between the first tile ribs 31. The first tile rib 31 refers to a panel tile rib located at the edge of the roof panel 30, and two roof panels 30 can be stacked on each other through the first tile ribs 31 at each edge, so that the two roof panels 30 can be assembled together.

[0090] Optional, such as Figure 1 As shown, the first tile rib 31 is provided with a snap-fit ​​protrusion 33; the inner surface of the snap-fit ​​protrusion 33 matches the outer surface of the snap-fit ​​protrusion 33, and the snap-fit ​​protrusion 33 is used to fix the two roof panels 30 when the two roof panels 30 are connected; the roof panel 30 is connected to the first sliding support 10 by a fastener 90 passing through the snap-fit ​​protrusion 33.

[0091] In order to reduce the construction difficulty and avoid assembly errors between adjacent roof panels 30, a snap-fit ​​protrusion 33 can be provided on each first tile rib 31. Thus, when assembling two adjacent roof panels 30, it is only necessary to overlap the snap-fit ​​protrusions 33 on the first tile ribs 31 at the edges of the two roof panels 30, so that the two adjacent roof panels 30 can be quickly aligned, thereby reducing the assembly errors caused by manual measurement and misalignment of the roof panels 30, and improving the assembly speed of the roof panels 30. At the same time, the snap-fit ​​protrusion 33 can also limit the installation position of the photovoltaic module 50 when installing the photovoltaic module 50. It is only necessary to place the photovoltaic module 50 whose size matches the distance between the two adjacent snap-fit ​​protrusions 33 between the two adjacent snap-fit ​​protrusions 33, so that the photovoltaic module 50 can be aligned with the installation position, which also reduces the construction difficulty and assembly error of installing the photovoltaic module 50 on the roof panel 30.

[0092] Optional, see Fig. 9 , Fig. 9 FIG. 4 shows a partial enlarged view of the installation of a second sliding support provided by an embodiment of the present invention, such as Fig. 9 As shown, the second tile rib 32 includes a tile rib upper wall 321 and a tile rib side wall 322 connected to both ends of the tile rib upper wall 321, the support body 21 of the second sliding support 20 matches the shape of the inner surface formed by the tile rib upper wall and the tile rib side wall 322, and the roof panel 30 is connected to the support body 21 via a fixing hole located on the tile rib side wall 322.

[0093] Since there is an angle between the rib upper wall 321 and the rib side wall 322, the position of the rib side wall 322 is lower than the position of the rib upper wall 321. When the fastener 90 is set on the rib side wall 322, the height of the fastener 90 will be lower than the horizontal plane position of the rib upper wall 321. Therefore, when the rib upper wall 321 carries the photovoltaic component 50, the fastener 90 on the rib side wall 322 will not interfere with the photovoltaic component 50, thereby ensuring that when the photovoltaic component 50 is under pressure, the fastener 90 connected to the second sliding support 20 on the second rib 32 will not interfere with the photovoltaic component 50, thereby preventing the photovoltaic component 50 from being worn and damaged by the fastener 90.

[0094] like Fig. 9As shown, a second nail groove 323 may be further provided on the rib side wall 322 of the second rib 32, and the second nail groove 323 is parallel to the rib upper wall 321 of the second rib 32. Since the second rib 32 will cover the second sliding support 20 during construction, the second sliding support 20 is blocked at this time, and the position of the junction between the support body 21 of the second sliding support 20 and the inner surface of the second rib 32 cannot be determined, which makes it difficult to install the fastener 90. Therefore, the second nail groove 323 may be provided, and the punching position of the fastener 90 may be determined by the second nail groove 323 during construction. Under the fixing effect of the second nail groove 323, the fastener 90 will not be offset on the outer surface of the second rib 32, which reduces the construction difficulty and improves the construction accuracy.

[0095] Optional, such as Figure 1 As shown, a limiting structure is provided on one side of the photovoltaic module 50 close to the roof panel 30; the limiting structure is composed of two limiting protrusions 51, the shape of which matches the panel tile rib, and the limiting structure is used to accommodate the panel tile rib, so as to avoid relative displacement between the photovoltaic module 50 and the roof panel 30. In the embodiment of the present invention, the limiting structure can be formed by two limiting protrusions 51 with triangular cross sections bonded to the bottom surface of the photovoltaic module 50 and arranged opposite to each other, and the bottom surface of the photovoltaic module 50 located between the two limiting protrusions 51. The limiting structure can match the shape of the panel tile rib, and is used to determine the relative position between the photovoltaic module 50 and the roof panel 30 when installing the photovoltaic module 50, reduce the difficulty of positioning the photovoltaic module 50 installed on the roof panel 30, and improve the installation accuracy of the photovoltaic module 50.

[0096] It should be noted that, in the embodiment of the present invention, since the snap-fit ​​protrusion 33 on the first rib 31 can also play the role of positioning the photovoltaic component 50, the limiting protrusion 51 may not be set when the snap-fit ​​protrusion 33 is set. Similarly, the snap-fit ​​protrusion 33 may not be set when the limiting protrusion 51 is set. Of course, the snap-fit ​​protrusion 33 and the limiting protrusion 51 may also exist at the same time to further improve the accuracy of determining the installation position of the photovoltaic component 50.

[0097] Optional, such as Figure 1 As shown, a bulge 41 is provided at the position where the waterproof cover 40 covers the fastener 90 on the roof panel 30 , and the bulge 41 is used to accommodate the portion of the fastener 90 on the roof panel 30 protruding from the surface of the roof panel 30 .

[0098] In the embodiment of the present invention, the roof panel 30 can be fixed to the house structure 60 by the roof support including the first sliding support 10 and / or the second sliding support 20, or the roof panel 30 can be directly fixedly connected to the house structure 60 by the fastener 90 penetrating the roof panel 30. Therefore, when the roof panel 30 is installed on the house structure 60, there will be a part of the fastener 90 structure protruding from the upper surface of the roof panel 30. In order to make the waterproof cover 40 fit better with the roof panel 30, a bulge 41 facing away from the roof panel 30 can be provided at the position where the waterproof cover 40 covers the fastener 90 on the roof panel 30, so that the bulge 41 can accommodate the fastener 90 located on the roof panel 30.

[0099] Optional, such as Figure 1 As shown, the panel tile ribs also include a third tile rib 34 , and the height of the third tile rib 34 close to the upper surface of the photovoltaic component 50 is lower than the height of the first tile rib 31 close to the upper surface of the photovoltaic component 50 and the height of the second tile rib 32 close to the upper surface of the photovoltaic component 50 .

[0100] Optional, such as Figure 1 As shown, an adhesive layer 91 is provided at the position where the photovoltaic component 50 covers the first tile rib 31 and the second tile rib 32, and a buffer layer 92 is provided at the position where the photovoltaic component 50 covers the third tile rib 34. The adhesive layer 91 and the buffer layer 92 are both located on the side of the photovoltaic component 50 close to the roof panel 30.

[0101] refer to Fig.10 , Fig.10 FIG. 4 shows a third tile rib assembly diagram provided by an embodiment of the present invention, such as Fig.10 As shown, since the upper surface of the third tile rib 34 is at a lower position, after the photovoltaic module 50 is installed on the roof panel 30, due to the support of the first tile rib 31 and / or the second tile rib 32, the gap between the upper surface of the third tile rib 34 and the photovoltaic module 50 will be larger than the gap between the photovoltaic module 50 and the first tile rib 31 and / or the second tile rib 32. Therefore, a buffer layer 92 with a certain thickness can be arranged between the third tile rib 34 and the roof panel 30. The buffer layer 92 can absorb the vibration of the photovoltaic module 50 and avoid the photovoltaic module 50 from being damaged due to resonance in strong winds. The buffer layer 92 can also absorb the pressure on the photovoltaic module 50, for example, it can avoid the possibility of damage to the photovoltaic module 50 when it is snowed or stepped on by construction workers. The third tile rib 34 can also include a third nail groove running through the upper surface of the third tile rib 34. The third nail groove can facilitate construction workers to fix fasteners 90 such as screws to avoid slipping when installing the fasteners 90. It can also play a role in limiting the installation position of the fasteners 90, thereby improving the installation accuracy of the roof component.

[0102] Optional, see Fig.11 , Fig.11 Another photovoltaic house structure diagram provided by an embodiment of the present invention is shown. Fig.11 As shown, the photovoltaic roof can be composed of a photovoltaic module 50, a waterproof cover 40 and a roof panel 30. The roof panel 30 is directly connected to the house structure 60 through a fastener 90. The waterproof cover 40 covers the roof panel 30 by means of adhesive, welding, etc., and the photovoltaic module 50 is connected to the upper surface of the waterproof cover 40 by means of adhesive, etc. In some cases, it may be necessary to lay only a small area of ​​photovoltaic roof, and the thermal expansion and contraction effect does not significantly affect the small area of ​​the roof panel 30. In this case, the first sliding support 10 and / or the second sliding support 20 may not be provided.

[0103] Optional, see Fig.12 and Fig.13 , Fig.12 A schematic diagram of installing a waterproof covering member provided by an embodiment of the present invention is shown. Fig.13 FIG. 1 shows a partial enlarged schematic diagram of the installation of a waterproof cover provided by an embodiment of the present invention. Fig.12 and Fig.13 As shown, adjacent roof panels 30 overlap each other and are fixedly connected by fasteners 90 in the overlapping area 35; before the roof panels 30 are installed, the roof panels 30 and the waterproof covering members 40 are compounded together in the non-overlapping area 36 by hot air welding or bonding; after the roof panels 30 overlap each other and are installed by fasteners 90, the waterproof covering members 40 and the roof panels 30 are compounded together in the overlapping area 35 by hot air welding or bonding, and adjacent waterproof covering members 40 overlap each other in the overlapping area 35 and are compounded with each other by hot air welding or bonding.

[0104] like Fig.11 As shown, the first tile ribs 31 between adjacent roof panels 30 may overlap each other, and the adjacent roof panels 30 may be fixedly connected by fasteners 90 passing through the two overlapping first tile ribs 31 .

[0105] Before the roof panels 30 are installed, since the roof panels 30 need to be fixedly connected by fasteners 90, in order to prevent the fasteners 90 from penetrating the waterproof covering members 40 thereon during the laying of the roof panels 30, the waterproof covering members 40 may not be pre-laminated in the overlapping areas 35 of the roof panels 30, and may be pre-laminated with the roof panels 30 only in the non-overlapping areas 36 of the roof panels 30 by hot air welding or bonding.

[0106] After the roof panel 30 is installed, since the fasteners 90 have been installed in the overlap area 35, the waterproof covering member 40 that has not been pre-laminated with the roof panel 30 in the overlap area 35 can be connected to the roof panel 30 by hot air welding or bonding. It should be noted that adjacent waterproof covering members 40 can overlap each other in the overlap area 35 to improve the sealing of the waterproof covering members 40 at the connection position. After the lower waterproof covering member 40 is fixedly connected to the roof panel 30, the upper waterproof covering member 40 is fixedly connected to the lower waterproof covering member 40 by hot air welding or bonding.

[0107] In this way, by pre-combining the waterproof covering 40 with the roof panel 30, the installation efficiency of the roof panel 30 and the waterproof covering 40 can be improved. Moreover, after the fasteners 90 are installed on the roof panel 30, the waterproof covering 40 in the overlapping area 35 of the roof panel 30 is connected to the roof panel 30 by hot air welding or bonding, thereby avoiding the fasteners 90 penetrating the waterproof covering 40 and causing a decrease in the waterproof effect.

[0108] Since the second tile rib 32 can also be provided with a fastener 90 to fix the roof panel 30 to the house structure 60, when the second tile rib 32 needs to be provided with a fastener 90, the overlap area 35 may include not only the first tile rib 31 but also the second tile rib 32. After the fastener 90 is installed on the first tile rib 31 and the second tile rib 32, the waterproof cover 40 is fixedly connected to the first tile rib 31 and the second tile rib 32 by hot air welding or gluing.

[0109] Optional, see Fig.14 , Fig.14 Another photovoltaic house structure diagram provided by an embodiment of the present invention is shown. Fig.14 As shown, the house structure 60 may further include a reinforcement layer 70 and a thermal insulation layer 80, wherein the reinforcement layer 70 may be a metal grid, a metal mesh or a metal plate, etc., and the thermal insulation layer 80 may be made of a material with a low thermal conductivity coefficient such as polyurethane foam. The reinforcement layer 70 may be directly connected to the house structure 60, and the thermal insulation layer 80 may be located between the roof support and the reinforcement layer 70, and the roof support may be connected to the reinforcement layer 70 via a fastener 90 passing through the thermal insulation layer 80.

[0110] It should be noted that, in the case where no roof support is provided, the roof panel 30 can be directly connected to the reinforcement layer 70 via the fasteners 90 passing through the insulation layer 80 .

[0111] In summary, in an embodiment of the present invention, a photovoltaic roof is disclosed, including: a roof panel 30, a waterproof covering 40, a photovoltaic module 50 and a roof support; the upper surface of the roof panel 30 is covered with the waterproof covering 40; the photovoltaic module 50 is installed on the surface of the waterproof covering 40 away from the roof panel 30; the roof panel 30 includes a support fixing hole covered by the waterproof covering 40, and the roof support is connected to the lower surface of the roof panel 30 by a fastener 90 passing through the support fixing hole. Under normal circumstances, fixing the roof panel 30 to the roof support by means of self-tapping screws, rivets, etc., which require drilling holes on the roof panel 30, can make the roof panel 30 more stable and can significantly improve the wind-resistant performance of the roof panel 30, but this method will result in poor waterproofing of the roof panel 30. In an embodiment of the present invention, a waterproof covering member 40 covering the fasteners 90 and the surface of the roof panel 30 is provided on the roof panel 30, so that the waterproofing performance of the roof panel 30 is improved while maintaining high wind-resistant performance. In addition, since the roof panel 30 has a higher stability, roof panels 30 with larger specifications and sizes can be selected for splicing, thereby increasing the size range of the compatible photovoltaic modules 50.

In an embodiment of the present invention, a waterproof covering member 40 covering the fasteners 90 and the surface of the roof panel 30 is provided on the roof panel 30, so that the waterproofing performance of the roof panel 30 is improved while maintaining high wind-resistant performance. In addition, since the roof panel 30 has a higher stability, roof panels 30 with larger specifications and sizes can be selected for splicing, thereby increasing the size range of the compatible photovoltaic modules 50.
