[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0046] Example 1: See Figures 1 to 6 As shown, a roof photovoltaic installation system with waterproof membrane and metal plate, comprising:

[0047] A clad metal plate 1, wherein the clad metal plate 1 is installed on a roof 2;

[0048] A photovoltaic assembly 3, wherein the photovoltaic assembly 3 is arranged directly above the clad metal plate 1, and the photovoltaic assembly 3 is connected to the clad metal plate 1 and the roof 2 via a photovoltaic connection mechanism 31;

[0049] A bridge frame 4, wherein the bridge frame 4 is installed on the laminated metal plate 1, and the top plane of the bridge frame 4 is arranged below the bottom plane of the photovoltaic assembly 3;

[0050] A threading tube 5, wherein the threading tube 5 is connected to the clad metal plate 1 via a first connecting member 51, the top of the threading tube 5 is arranged above the clad metal plate 1, and the bottom of the threading tube 5 passes through the clad metal plate 1 and the roof 2 in sequence and is arranged below the roof 2;

[0051] A connecting line 6 , one end of which is connected to the photovoltaic module 3 , and the other end of which passes through the bridge 4 and the threading tube 5 in sequence and is connected to a terminal below the roof 2 .

[0052] In the present invention, the laminated metal plate includes a metal plate and a waterproof layer laminated on the top surface of the metal plate, and the waterproof layer is a PVC / TPO material, which plays a waterproof role. When it is necessary to install a photovoltaic system above it, the photovoltaic assembly is connected through a photovoltaic connection mechanism, a laminated metal plate and a roof. It is connected to the roof, which can ensure the strength of the photovoltaic connection mechanism after installation and will not be deformed. It is also connected to the laminated metal plate, and the position where the photovoltaic connection mechanism penetrates the laminated metal plate can be sealed to prevent water leakage at the connection between the two, thereby ensuring a waterproof effect. The bridge is arranged below the photovoltaic assembly, wherein the bridge is a hollow structure with two ends passing through, which is used for the passage and arrangement of connection lines, so that the connection lines will not be messy and will be more beautiful. Preferably, in this embodiment, the bridge is composed of two U-shaped plates, including a U-shaped plate with an opening facing upward and a U-shaped plate with an opening facing downward. The U-shaped plate with an opening facing downward is covered on the top of the U-shaped plate with an opening facing upward, and the two sides of the U-shaped plate with an opening facing downward are respectively located outside the two sides of the U-shaped plate with an opening facing upward. In this way, if rainwater drips onto the bridge from above, it will be blocked by the U-shaped plate with an opening facing downward, and will not directly drip into the U-shaped groove of the U-shaped plate with an opening facing upward, that is, rainwater will not drip into the bridge, and rainwater can be prevented from being deposited in the bridge as much as possible, and short circuits caused by aging of the lines can be prevented, which is safer. In addition, the top plane of the bridge is above the bottom plane of the photovoltaic module. In this way, the bridge can be set below the photovoltaic module, and the photovoltaic module can be used to block the sunlight for the connecting lines and the bridge, preventing the bridge and the connecting lines from being exposed to the sun and rain for a long time, thereby shortening the service life. The wire conduit is used to connect the connecting lines gathered in the corresponding bridge through the clad metal plate and the roof and the terminal. It not only provides a channel for the connecting lines to pass through the clad metal plate and the roof, but also can prevent water leakage at that place.

[0053] See also Figure 1 , 2As shown, the clad metal plate 1 is provided with a plurality of arches 11 at intervals, and the plurality of arches 11 are arranged at intervals. In the present invention, the arches form a wave crest shape, and the adjacent arches form a wave trough shape, so that the clad metal plate forms a wave crest and trough shape, which can increase the strength of the clad metal plate. Furthermore, the trough forms a drainage groove, so that the roof will not accumulate water, and the problem of excessive load-bearing caused by water accumulation on the roof is prevented. Among them, in the present invention, the roof 2 is a flexible roof, and the roof includes an insulation layer 21, a steel mesh 22 and a roof purlin 23 arranged in sequence from top to bottom. The bottom surface of the clad metal plate is against the top surface of the insulation layer, and is connected to the purlin of the roof through the first self-tapping screw 24. The insulation layer is a flexible layer, so the clad metal plate adopts a wave crest and trough structure, which can not only increase the overall strength of the roof, but also facilitate drainage, prevent the problem of excessive load-bearing caused by water accumulation on the roof, and try not to affect the insulation layer as much as possible to prevent damage to the roof insulation layer.

[0054] See also Figure 1 , 2 As shown in FIGS. 3 and 5 , the bridge frame 4 is disposed above the top plane of the arch 11 , the bridge frame 4 is installed on the laminated metal plate 1 via a connecting portion 41 , and both ends of the connecting portion 41 are installed on the two arches 11 respectively.

[0055] In this embodiment, the two ends of the connecting part are respectively installed on two adjacent arches, and the bridge frame is arranged above the covering metal plate between the two adjacent arches. In this way, the bridge frame can be raised so that the troughs between the adjacent arches can be drained and ventilated normally, which not only prevents water from entering the bridge frame, but also allows normal ventilation and heat dissipation underneath.

[0056] See also Figure 2 , 5 As shown, the connecting portion 41 includes at least two positioning components arranged along the extension direction of the bridge frame, and the bridge frame 4 is installed on the positioning components;

[0057] The positioning assembly includes a support plate 42, a limit plate 43 and at least two mounting plates 44, the bottom of each mounting plate 44 is respectively mounted on one of the arches 11, the extension direction of the support plate is perpendicular to the extension direction of the bridge frame 4, the two ends of the support plate 42 respectively abut against the top surfaces of at least two mounting plates 44, the bottom of the bridge frame 4 abuts against or is installed on the top surface of the support plate 42, the inner surface of the limit plate 43 abuts against the outer wall of the bridge frame 44, the end bottom surface of the limit plate 43 abuts against the top surface of the support plate 42, and the two ends of the limit plate 43 are respectively connected to the support plate 42 and a mounting plate 44 via a support screw 45, and the limit plate 43 limits the bridge frame 4 on the support plate 42.

[0058] In this embodiment, the threading tube is installed on the clad metal plate at one end of the bridge, and is arranged between adjacent arches. In this way, the threading tube can reduce the height space occupied as much as possible, so that the photovoltaic module can also be installed above it, and the installation height of the photovoltaic module will not be increased. The mounting plate is directly mounted on the arch of the clad metal plate, and the bottom of the support screw is connected to the mounting plate. The bridge is placed on the support plate, and the support plate is used to support the bridge. The limit plate is then pressed on the top surface of the bridge, and the two ends of the limit plate are respectively connected to the support screw, so that the bridge can be quickly installed and fixed. In this embodiment, the bridge is connected to the clad metal plate through two sets of positioning components, and the two ends of the bridge are fixed by two sets of positioning components. Of course, if the length of the bridge is longer, in order to prevent the middle part of the bridge from being deformed by weight, more positioning components can be set to support and limit the bridge to prevent the bridge from deforming.

[0059] See also Figure 2 , 5 As shown, the bottom surface of the mounting plate 43 is provided with a groove matching the arch, and the two sides of the bottom of the mounting plate 43 are also provided with extension plates 46 extending outwards, and the bottom surface of the extension plate 46 is connected to the top surface of the cladding metal plate 1 between the adjacent arches 11;

[0060] A connecting piece 47 is also provided at the bottom of the support screw 45, the bottom surface of the connecting piece 47 abuts against the surface of the arch 11, and the top surface of the connecting piece 47 abuts against the inner wall of the groove. The top of the support screw 45 passes through the mounting plate 44, the support plate 42 and the limiting plate 43 in sequence and is arranged above the limiting plate 43; two nuts 48 are screwed on the support screw 45, the bottom surface of one nut 48 abuts against the top surface of the limiting plate 43, and the top surface of the other nut 48 abuts against the bottom surface of the support plate 42.

[0061] In this embodiment, the mounting plate is made of the same material as the top surface material of the clad metal plate, that is, the mounting plate is made of PVC or TPO waterproof coiled material, which is a flexible material and is directly connected to the arch of the clad metal plate by heat welding. It can realize the quick connection and fixation of the mounting plate and the clad metal plate, and it will not damage the clad metal plate, and there is no need to open a hole on the clad metal plate, which can prevent the occurrence of water leakage. In addition, the mounting plate and the clad metal plate have strong pull-out resistance after heat welding. The connecting piece is made of metal material, which is placed between the mounting plate and the clad metal plate. The size of the connecting piece will be smaller than the size of the mounting plate. Therefore, after the connecting piece is against the arch, when the mounting plate is against the connecting piece again, the mounting plate outside the connecting piece will be against the clad metal plate, and then it will be heat welded with the clad metal plate, which can firmly limit the connecting piece on the arch, ensuring the installation firmness of the connecting piece. The bottom of the support screw is fixedly connected to the connecting piece, and preferably the bottom of the support screw and the connecting piece are welded, and the top of the support screw passes through the mounting plate and is located above the mounting plate. After the mounting plate limits the connecting piece, the support screw can be firmly limited. In this embodiment, the cross-section of the arch is an isosceles trapezoidal structure that opens downward. Therefore, in order to increase the contact area between the connecting piece and the clad metal plate, the connecting piece also adopts an isosceles trapezoidal structure that opens downward, and the mounting plate is also an isosceles trapezoidal structure that opens downward. Furthermore, in order to increase the contact area between the mounting plate and the clad metal plate, extension plates are arranged on both sides of the mounting plate, and the extension plates are fixed by heat welding to the bottom surface of the clad metal plate between adjacent arches, so as to increase the welding firmness of the mounting plate and the clad metal plate. Furthermore, the bridge frame can also be screwed to the support plate by self-tapping screws to prevent the bridge frame from moving, thereby ensuring the firmness and stability of the installation.

[0062] More preferably, the top surface of the connecting piece is fixed to the top surface of the mounting plate by bonding or welding, so that the connecting piece and the mounting plate are integrated, ensuring that after the mounting plate is installed, the connecting piece and the supporting screw rod will not be relatively displaced or shaken.

[0063] Holes are set at both ends of the support plate, and the support screws are sleeved through the holes. The bottom of the support plate is supported by the nuts below, and the bridge is directly placed on the support plate and supported by the support plate. The middle bottom surface of the limit plate abuts against the top surface of the bridge, and the bottom surfaces of its two ends respectively abut against the top surfaces of the support plates on both sides of the bridge, and then the limit plate is screwed together through the nuts and support screws above, and the limit plate is limited to abut against the support plate. More preferably, in order to prevent the bridge from deviating and arching close to one side, the middle part of the bottom surface of the limit plate has a U-shaped groove that matches the shape of the bridge, the top surface of the U-shaped groove abuts against the top surface of the bridge, and the two side walls of the U-shaped groove abut against the two side walls of the bridge.

[0064] See also Figure 2 ,5 As shown, in order to increase the strength of the support plate, the support plate 42 adopts an L-shaped structure, which includes a horizontal plate 420 and a vertical plate 421. The horizontal plate 420 is sleeved on the support screw 45, and the top of the vertical plate 421 is connected to one end of the horizontal plate 420, which can effectively increase the strength of the horizontal plate and increase the anti-deformation ability. At the same time, the setting of the two nuts can adjust the height of the bridge frame by adjusting the positions of the two nuts on the support screw. According to the actual situation, the bridge frame can be parallel to the horizontal plane or tilted. Even if water enters the bridge frame, due to its tilt, the water inside can be discharged smoothly and smoothly to prevent water accumulation.

[0065] See also Figure 6 As shown, the first connecting member 51 includes a coaxially arranged first connecting plate 52 and a first sealing plate 53, the outer diameter of the first connecting plate 52 is smaller than the outer diameter of the first sealing plate 53, the first connecting plate 52 is coaxially arranged below the first sealing plate 53, the bottom surface of the first connecting plate 52 is against the top surface of the composite metal plate 1, and the bottom surface of the first sealing plate 53 outside the first connecting plate 52 is sealed and connected to the top surface of the composite metal plate 1.

[0066] The wire threading tube 5 includes a first connecting tube 54 and a second connecting tube 55. The middle outer surface of the first connecting tube 54 is sealed and connected to the first connecting piece 51. The bottom of the first connecting tube 54 passes through the clad metal plate 1 and the roof 2 and is arranged below the roof 2. The top of the first connecting tube 54 is arranged above the top surface of the first connecting piece 51. The first connecting tube and the second connecting tube are both hollow structures with both ends passing through, which is convenient for threading.

[0067] The second connecting tube 55 is an arc-shaped structure, the first end of the second connecting tube 55 is connected to the top of the first connecting tube 54, the second end of the second connecting tube 55 is arranged toward the top surface of the laminated metal plate 1, and a rubber sleeve 56 is sleeved on the second end of the second connecting tube 55.

[0068] In this embodiment, the first sealing plate is also made of the same PVC or TPO material as the waterproof membrane. The top surface of the first connecting plate can be connected to the first sealing plate without being fixed, or it can be connected by bonding or fixing. In this embodiment, the top surface of the first connecting plate and the middle part of the bottom surface of the first sealing plate are bonded / welded and fixed. The first connecting plate is a metal plate. The first connecting tube is arranged perpendicular to the first connecting plate. The middle outer surface of the first connecting tube and the center of the first connecting plate are welded and fixed. The first sealing plate and the first connecting tube are also sealed at the connection, thereby preventing water leakage there. When installing the threading tube, first make a hole in the clad metal plate and the roof, then the bottom of the first connecting tube passes through the hole from the top of the clad metal plate to the bottom of the roof, and after the first connecting plate abuts against the top surface of the clad metal plate, the bottom surface of the first sealing plate at the outer edge of the first connecting plate also abuts against the top surface of the clad metal plate, and then the connection between the first sealing plate and the clad metal plate is welded by heat welding, so that the connection between the first connecting plate and the clad metal plate is sealed to prevent water from flowing into the hole from the gap between the first connecting plate and the clad metal plate, thereby preventing water leakage. This method is also convenient for the installation of the threading tube. When installing the threading tube, you only need to make a hole in the corresponding position, then pass the first connecting tube through the hole, and then quickly heat weld the first sealing plate and the clad metal plate by heat welding.

[0069] Taking the direction shown in the figure as an example, the second connecting tube is an arc-shaped structure that opens downwards, which is a C-shaped structure that opens downwards, and its first end is connected and communicated with the top of the first connecting tube, and the other end is set downwards, facing the cladding metal plate, that is, the opening of the threading tube above the top surface of the cladding metal plate is set downwards. In this way, it is prevented that rainwater directly passes through the threading tube and enters the room under the roof when it rains. More preferably, the plane of the second end of the second connecting tube is set above the top plane of the side arch, especially the highest point of the second connecting tube will be higher than the height of the adjacent arch, so that even if water accumulates between adjacent arches, water will not be discharged from the threading tube into the room. Due to the existence of a bend in the threading tube, when threading, especially when passing from the second end to the threading tube, in order to prevent the second end from scratching the connection line, a rubber sleeve is set at the second end to protect the connection line and prevent the outer skin of the connection line from being scratched or damaged during the threading process.

[0070] See also Figure 1 , 3 As shown in , 4 , the photovoltaic connection mechanism 31 includes a photovoltaic bracket 32 ​​and a bracket connection component 30 , the bottom of the photovoltaic bracket 32 ​​is connected to the laminated metal plate 1 and the roof 2 via a plurality of the bracket connection components 30 , and the photovoltaic component 3 is installed on the photovoltaic bracket 32 ​​.

[0071] In this embodiment, the photovoltaic bracket is an existing structure, and its structure is the same or similar to the photovoltaic mounting bracket assembly structure in the application number "202410914065.0" and the patent name "Photovoltaic system installation structure with a flexible roof having safety attributes". Similarly, it is also provided with a fire barrier assembly (not shown in the figure), and its structure is the same as the fire barrier assembly structure in the application number "202410914065.0" and the patent name "Photovoltaic system installation structure with a flexible roof having safety attributes". The fire barrier assembly will be arranged between the two main profiles, which will not be described here. However, the bracket connection assembly structure is different from the anchor in the patent. In this application, the bracket connection assembly is connected and fixed to the profile bracket of the photovoltaic bracket.

[0072] See also Figure 3 , 4 As shown, the bracket connection assembly 30 includes a coaxially arranged second connecting member 33, a second self-tapping screw 34, a second screw 35 and two second nuts 36, the second self-tapping screw 36 is installed on the bottom surface of the second connecting member 33, the bottom of the second self-tapping screw 36 passes through the cladding metal plate 1 and is connected to the roof 2, the second screw 35 is installed on the top of the second connecting member 33, the top of the second screw 35 is penetrated on the photovoltaic bracket 32, two second nuts 36 are screwed on the second screw 35, and the two nuts limit the photovoltaic bracket on the second screw; the bottom surface of one second nut 36 abuts against the bottom surface of the inner end of the photovoltaic bracket 32, and the top surface of the other second nut 36 abuts against the top surface of the photovoltaic bracket 32;

[0073] A second seal 37 is sleeved on the second screw 35 above the second connecting member 33. The outer diameter of the second seal 37 is larger than the outer diameter of the second connecting member 33. The inner wall of the second seal 37 is sealed and connected with the contact point of the second screw 35. The bottom surface of the second seal 37 is fixedly connected with the top surface of the second connecting member 33. The bottom surface of the second seal 37 outside the second connecting member 33 is sealed and connected with the top surface of the laminated metal plate 1.

[0074] In this embodiment, the bracket connection assembly is arranged between adjacent arches. Since the bottom of the arch is a hollow structure, it cannot directly contact the roof. Therefore, if the bracket connection assembly is installed on the arch, the arch is easy to deform, thereby affecting the installation and fixation of the photovoltaic bracket. The bottom of the second self-tapping screw passes through the clad metal plate, the thermal insulation layer, the wire mesh in sequence and is connected to the roof purlin; when it is installed, the second self-tapping screw is rotated to pass through the clad metal plate, the thermal insulation layer, the wire mesh in sequence, and then is screwed and fixed to the roof purlin to achieve the fixation of the second connecting member and the roof. The second connecting member is made of metal, and the second self-tapping screw and the second screw are respectively fixed to the bottom surface and the top surface of the second connecting member. The second sealing member is also made of PVC or TPO material which is the same as the waterproof layer material of the top of the clad metal plate. After the second connecting member abuts against the top surface of the clad metal plate, the bottom surface of the second sealing member located outside the outer edge of the second connecting member abuts against the waterproof layer on the top surface of the clad metal plate, and then the second sealing member and the clad metal plate are connected and fixed by heat welding. It not only plays the role of connecting with the clad metal plate, but also can seal the connection between the second self-tapping screw and the clad metal plate to prevent water leakage. The top surface of the second connecting member and the top surface of the second sealing member are preferably fixed by bonding or welding, so that the second connecting member and the second sealing member form an integral structure with strong firmness, and also prevent water leakage at the connection or contact between the top surface of the second connecting member and the bottom surface of the second sealing member. After the bracket connection assembly is fixed to the roof, the covering and the metal plate, the photovoltaic bracket is connected to the second screw, and the photovoltaic bracket is supported by the second nut below, and the photovoltaic bracket is restricted by the second nut above, so that the photovoltaic bracket can be fixed. Among them, by adjusting the position of the two second nuts relative to the second connecting member, the height between the photovoltaic bracket and the covering metal plate can be adjusted to meet the requirements of subsequent optical component installation. In this way, the photovoltaic component is supported by the photovoltaic bracket, and the photovoltaic bracket is mainly transmitted to the purlin of the roof through the bracket connection assembly. The main load-bearing is the purlin, not the covering metal plate, so as to ensure the installation firmness and strength of the photovoltaic component. More preferably, in order to prevent the second nut from loosening, causing the photovoltaic bracket to shift and affecting the installation stability and strength of the photovoltaic component, after the photovoltaic bracket and the bracket connection assembly are installed and adjusted, welding can be performed at the connection between the second screw and the photovoltaic bracket. It is sufficient to simply set a few welding points. A few welding points can also be welded at the connection between the second screw and the second nut to ensure the firmness of the connection and prevent loosening.

[0075] See also Figure 3As shown, the bottom surface of the laminated metal plate 1 is against the top surface of the roof 2, and the laminated metal plate 1 is connected to the roof 2 via a plurality of first self-tapping screws 24; a third sealing member 25 is also provided above the top surface of each of the first self-tapping screws 24, and the outer edge of the bottom surface of the third sealing member 25 is sealed and connected to the laminated metal plate 1.

[0076] In this embodiment, the bottom of the first self-tapping screw is connected and fixed to the purlin to ensure the installation firmness and strength of the clad metal plate. In this embodiment, the clad metal plate on the roof is spliced ​​by multiple clad metal plates of a certain size. The edge of each clad metal plate will overlap the edge of the adjacent clad metal plate, and the first self-tapping screw will be set at the overlap to fix the adjacent clad metal plates at the same time. Since the first self-tapping screw will damage the waterproof layer on the top of the clad metal plate, the third sealing member is covered on it. The third sealing member is made of PVC or TPO material that is the same as the waterproof layer material. The cover is arranged above the third self-tapping screw, and the outer side is outside the third self-tapping screw and against the top surface of the clad metal plate. It is fixed to the top surface of the clad metal plate by heat welding, which can seal the connection between the third self-tapping screw and the clad metal plate to prevent water leakage.
