Waterproofing and photovoltaic roof

[0001] Priority information

[0002] This application claims priority to and the benefit of the filing date of Chinese Patent Application No. 202410637603.6, filed May 21, 2024, and is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the technical field of photovoltaic installation, in particular to a waterproofing and photovoltaic roof. BACKGROUND

[0004] Photovoltaic tiles are generally used for inclined building surfaces, which have both power generation function and building component and building material function, and can even increase aesthetic effect by changing the color of the photovoltaic tiles.

[0005] Currently, two adjacent photovoltaic tiles are directly connected in the form of lapping. In some places with relatively large amount of precipitation, rainwater is prone to backflow, causing safety hazards. Therefore, a waterproofing is usually arranged at the lapping position between two photovoltaic tiles. However, due to the processing error, the conventional waterproofing cannot completely cover the gap between the two photovoltaic tiles in the actual application process, and there is a risk of water leakage.

[0006] SUMMARY

[0007] In view of the problem that the conventional waterproofing cannot completely cover the gap between the two photovoltaic tiles, resulting in the risk of water leakage, the present application aims to provide a waterproofing and photovoltaic roof. The waterproofing can completely cover the gap between the two photovoltaic tiles, thereby helping to improve the waterproofing effect.

[0008] To this end, the first aspect of the present application is to provide a waterproofing.

[0009] The second aspect of the present application is to provide a photovoltaic roof.

[0010] Therefore, according to the first aspect of the present application, a waterproofing is provided, which is arranged at the lapping position of the first component and the second component; the waterproofing comprises: a waterproofing body, the upper side of which is in contact with the first component, and the lower side of which is in contact with the second component; a water shedding strip, which has a combined side and a free side; the combined side is connected to the upper side of the waterproofing body; the free side is arranged opposite to the combined side and can swing downward under the weight of the first component; and a structural adhesive is arranged on the lower side of the waterproofing body to contact the second component.

[0011] In actual application, due to the non-uniform gap between the first component and the second component when they are overlapped, and due to the processing error, the conventional waterproof part cannot completely seal the gap between the first component and the second component, and there is a risk of water leakage. However, by using the waterproof part, the gap between the second component and the waterproof body is completely covered by the structural adhesive, and due to the resilience of the water shedding strip, the water shedding strip can swing downward under the weight of the first component to absorb the gap error, so that the water shedding strip completely covers the gap between the first component and the waterproof body. In this way, the gap between the first component and the second component is completely covered, thereby achieving good waterproof effect.

[0012] In some technical solutions, optionally, the waterproof body includes a first edge, a second edge, a third edge and a fourth edge; the first edge and the third edge are oppositely and spaced apart; the second edge and the fourth edge are oppositely and spaced apart; wherein the second edge connects the first edge and the third edge; and the fourth edge connects the first edge and the third edge. Thus, a frame structure is defined. The frame structure has good stability, so that when overlapped, the waterproof body can support the first component, avoiding hard contact between the first component and the second component, so that the waterproof body also has the function of protecting the first component and the second component.

[0013] In some technical solutions, optionally, the water shedding strip extends from the first edge to the direction away from the third edge and the fourth edge, or the water shedding strip extends from the second edge to the direction away from the third edge and the fourth edge. In this way, during installation, the free side of the water shedding strip can be turned downward without other operations, thereby facilitating installation, and at the same time, after installation, the water shedding strip cannot be seen from the appearance, which helps to ensure the aesthetic appearance of the whole.

[0014] In some technical solutions, optionally, the second edge and the fourth edge extend in the direction away from the first edge to form a protruding portion, and a containing groove is formed between the protruding portion and the third edge, the containing groove being used for containing the structural adhesive. In this way, the structural adhesive can be prevented from overflowing, thereby helping to improve the waterproof effect.

[0015] In some technical solutions, optionally, a boss is arranged in the containing groove, the boss extending from the third edge to the direction away from the first edge, and the boss divides the containing groove into two parts.

[0016] During installation, the structural adhesive is filled at the position of the boss, so that the structural adhesive flows to both sides of the containing groove under the action of the boss, so that the structural adhesive and the surface of the second component are in full contact, so that the structural adhesive completely covers the gap between the second component and the waterproof body, thereby helping to improve the waterproof effect.

[0017] In some embodiments, the waterproofing piece further comprises a lap strip, the lap strip is connected to the waterproof body, and the lap strip extends from the second side to a direction away from the fourth side. In actual applications, the underside of the lap strip is provided with a back adhesive. In this way, the back adhesive is used as a positioning structure before the curing of the structural adhesive, thereby helping to improve the waterproofing effect.

[0018] According to a second aspect of the present application, the present application further provides a photovoltaic roof, comprising a photovoltaic assembly and the waterproofing piece according to any one of the preceding embodiments. In this way, the photovoltaic roof has all the beneficial effects disclosed in any one of the preceding embodiments, which will not be described herein again.

[0019] In some embodiments, the photovoltaic assembly comprises a plurality of photovoltaic tiles, the plurality of photovoltaic tiles are connected by means of lap joint, the upper side of the lap joint of the photovoltaic tile is in contact with the underside of the waterproof body, the lower side of the lap joint of the photovoltaic tile is in contact with the upper side of the waterproof body, and the flashing strip is used to seal the gap formed between the upper side of the waterproof body and the lower side of the lap joint of the photovoltaic tile. In this way, the problems in the related art are solved, and the waterproofing effect of the photovoltaic roof is effectively improved.

[0020] In some embodiments, the photovoltaic roof further comprises a plurality of roof battens, the plurality of roof battens are arranged equidistantly and in parallel, and the photovoltaic roof further comprises a plurality of hanging pieces, each of the plurality of hanging pieces is arranged on the photovoltaic tile and connected to the roof batten, so as to fix the photovoltaic tile on the roof batten.

[0021] In the above-mentioned embodiments, the hanging piece comprises a first connecting portion and a second connecting portion, the first connecting portion is connected to the photovoltaic tile, and the second connecting portion is connected to the roof batten.

[0030] In order to enable a clearer understanding of the above-mentioned objects, features and advantages of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0032] The waterproof member and the photovoltaic roof provided by the embodiments of the present application will be described in detail below with reference to specific embodiments and application scenarios in combination with Figs. 1 to 5.

[0033] Referring to Fig. 1, some embodiments of the present application disclose a waterproof member 100 arranged at the overlapping and lapping position of a first component and a second component, which structure comprises a waterproof body 110, a water shedding strip 120 and a structural adhesive 130.

[0034] Specifically, the upper side of the waterproof body 110 is in contact with the first component, and the lower side is in contact with the second component to form a main waterproof structure. The water shedding strip 120 is connected to the upper side of the waterproof body 110, and the side where the water shedding strip 120 and the waterproof body 110 are connected is taken as a combined side, and the side opposite to the combined side is taken as a free side; and the free side can swing downward (as shown by the arrow in Fig. 1) under the action of the first component. The structural adhesive 130 is arranged on the lower side of the waterproof body 110 to abut against the second component.

[0035] In actual application, due to the non-uniformity of the gap when the first component and the second component are overlapped, and due to the processing error, the conventional waterproof member cannot completely seal the gap between the first component and the second component, and there is a risk of water leakage. However, by using the waterproof member 100 described above, the gap between the second component and the waterproof body 110 is completely covered by the structural adhesive 130, and at the same time, due to the resilience of the water shedding strip 120, the water shedding strip 120 can swing downward under the weight of the first component to absorb the gap error, so that the water shedding strip 120 completely covers the gap between the first component and the waterproof body 110. In this way, the gap between the first component and the second component is completely covered, thereby achieving a good waterproof effect.

[0036] In the above implementation, referring to FIG. 2 and FIG. 3, the waterproof body 110 is a frame structure, which has good stability, so that when the first part is overlapped, the waterproof body 110 can support the first part, avoid the hard contact between the first part and the second part, and has the function of protecting the first part and the second part.

[0037] Specifically, the waterproof body includes a first side 113, a second side 114, a third side 115 and a fourth side 116. The first side 113 and the third side 115 are oppositely and spacedly arranged; the second side 114 and the fourth side 116 are oppositely and spacedly arranged; the second side 114 connects the first side 113 and the third side 115; and the fourth side 116 connects the first side 113 and the third side 115. In this way, the frame structure of the waterproof body 110 is defined.

[0038] In some embodiments, for the convenience of installation, the water shedding strip 120 extends obliquely from the first side 113 to the direction away from the third side 115 and the fourth side 116. In this way, when installed, the free side of the water shedding strip 120 can be turned downward without other operations, so as to facilitate the installation, and at the same time, after installation, the water shedding strip 120 cannot be seen from the appearance, which helps to ensure the aesthetic appearance of the whole. It can be understood that the water shedding strip 120 can also be obliquely extended from the second side 114 to the direction away from the third side 115 and the fourth side 116.

[0039] Referring to FIG. 2 and FIG. 3, in some embodiments, the second side 114 and the fourth side 116 extend in the direction away from the first side 113 to form a protruding portion, and the protruding portion and the third side form a containing groove 111 for containing the structural adhesive 130. In this way, the overflow of the structural adhesive 130 can be avoided, thereby helping to improve the waterproof effect.

[0040] In the above embodiments, the containing groove 111 is provided with a boss 112 extending from the third side 115 to the direction away from the first side 113, and the boss 112 separates the containing groove 111 into two parts. When installed, the structural adhesive 130 is filled at the position of the boss 112, so that the structural adhesive 130 flows to both sides of the containing groove 111 under the action of the boss 112. In this way, the structural adhesive 130 can fully contact the surface of the second part, so that the structural adhesive completely covers the gap between the second part and the waterproof body 110, thereby helping to improve the waterproof effect.

[0041] In some embodiments, the waterproof piece 100 further includes an overlapping strip 140 for connecting with the second part to fix the waterproof piece 100 on the second part, so that the positioning can be realized before the structural adhesive 130 solidifies, thereby helping to improve the waterproof effect.

[0042] Specifically, the lap strip 140 is connected with the waterproof body 110; wherein the lap strip 140 extends from the second edge 114 to a direction away from the fourth edge 116. In actual application, the lower side of the lap strip 140 is provided with the back adhesive 150. Before installation, the protective film of the back adhesive 150 is torn off, so that the waterproof piece 100 is fixed on the second component. In this way, the back adhesive 150 serves as positioning before curing of the structural adhesive 130, thereby helping to improve the waterproof effect.

[0043] Referring to FIGS. 4 and 5, in some embodiments, the present application also discloses a photovoltaic roof 300 comprising the photovoltaic assembly 200 and the waterproof piece 100 disclosed in any of the above embodiments. Specifically, the waterproof piece 100 is arranged on the photovoltaic assembly 200. In this way, the photovoltaic roof has all the beneficial effects of any of the above technical solutions, which will not be repeated here.

[0044] In some embodiments, the photovoltaic assembly 200 comprises a plurality of photovoltaic tiles 210; the plurality of photovoltaic tiles 210 are connected by lap joint; the upper lap side of the photovoltaic tile 210 and the lower side of the waterproof body 110 are in contact; the lower lap side of the photovoltaic tile 210 and the upper side of the waterproof body 110 are in contact; and the water shedding strip 120 is used to seal the gap formed between the upper side of the waterproof body 110 and the lower lap side of the photovoltaic tile 210. In this way, the problems in the related art are solved, and the waterproof effect of the photovoltaic roof 300 is effectively improved.

[0045] Illustratively, the photovoltaic tile 210 is a curved tile, and the curved edges between two adjacent photovoltaic tiles 210 are connected by lap joint. The waterproof piece 100 is arranged at the lap joint position between the two adjacent photovoltaic tiles 210.

[0046] In the related art, because the radius of the upper surface of the photovoltaic tile and the radius of the lower surface of the photovoltaic tile differ by the thickness of the photovoltaic tile, when the two adjacent photovoltaic tiles are lap jointed, the gap between them is not uniform. In addition, due to the error caused by processing, the conventional waterproof piece cannot cover the gap between the two adjacent photovoltaic tiles, and there is a risk of water leakage. The embodiments of the present application solve the problems in the related art by arranging the waterproof piece 100 disclosed in any of the above embodiments between the two adjacent photovoltaic tiles 210. First, the waterproof body 110 forms a main seal, at the same time, the structural adhesive 130 completely covers the gap between the lower photovoltaic tile 210 and the lower side of the waterproof body 110, and the water shedding strip 120 completely covers the gap between the upper photovoltaic tile 210 and the upper side of the waterproof body 110 by swinging up and down, thereby solving the problems in the related art and effectively improving the waterproof effect of the photovoltaic roof 300.

[0047] Specifically, the photovoltaic roof further comprises a plurality of keels 310 and a plurality of hangers 320. The plurality of keels 310 are arranged equidistantly and in parallel; each of the plurality of hangers 320 is arranged on the photovoltaic tile 210 and connected with the keel 310 so as to fix the photovoltaic tile 210 on the keel 310.

[0048] In some embodiments, the hanger 320 comprises a first connecting part 321 and a second connecting part 322; the first connecting part 321 is connected with the photovoltaic tile 210; the second connecting part 322 is connected with the keel 310. Specifically, the first connecting part 321 is inserted into the edge of the photovoltaic tile 210 below the overlapping position, and the second connecting part 322 is fixed with the keel 310 by screw connection.

[0049] In some embodiments, the straight edge of the photovoltaic tile 210 is provided with a connecting frame 220, which can effectively protect the photovoltaic tile 210 and facilitate the installation of the photovoltaic tile 210.

[0050] In some embodiments, the second connecting part 322 is formed with a hook 323 in a direction away from the photovoltaic tile 210, and the hook 323 is engaged with the keel 310. In this way, the installation of the hanger 320 is facilitated, and the stability of the hanger 320 is effectively improved.
