Description

Technical Field

[0001] The present application belongs to the field of building construction technology, and in particular, relates to a support and photovoltaic panel installation system. Background Art

[0002] In traditional metal roof photovoltaic systems, whether it is a T-type plate or an angle-type plate, the commonly used connection system is a clamp, which is clamped on the crest of the steel plate. When connecting the angle-type plate, the bite force of the clamp is very limited, and the pull-out force is basically around 1000N to 2000N. Due to the low pull-out value, there is a risk of being blown away by the wind.

[0003] When installing the clamp on the T-type plate, it is necessary to drill holes and use drill nails to fix it on the crest of the steel plate. Although this installation method has a high pull-out value for the angle-type clamp, each clamp needs to be fixed with four screws, so there is a great hidden danger in the screw position. The general treatment method is to use weather-resistant glue for sealing. Weather-resistant glue is prone to aging and cracking due to long-term exposure to vibration and deformation. No matter which form of fixing is used for angle-type clamps and T-type clamps, there are certain risks and hidden dangers, which will cause local paint removal and modification of the steel plate, and poor fixing and sealing.

[0030] Traditional metal roof clamps are used to fix rails and photovoltaic modules, so there is a risk of insufficient bite force causing the photovoltaic modules to detach; secondly, if screws are used to fix the clamps, there is a risk of water leakage.

[0031] In order to solve the problems of the prior art, an embodiment of the present application provides a support and a photovoltaic panel installation system.

[0032] The support provided in the embodiment of the present application is first introduced below. Figure 1 A schematic structural diagram of a support provided in one embodiment of the present application is shown.

[0033] like Figure 1 As shown, the support includes: a fixing member 101, which is used to be fixedly connected to the structural plate 2; a screw rod 100, which can pass through the fixing member 101, and the first end 100a of the screw rod 100 is connected to the fixing member 101; a chassis assembly, which is sleeved on the screw rod 100, and the distance between the screw rod 100 and the fixing member 101 is adjustable, and the chassis assembly includes a stacked supporting chassis 102, a sealing and waterproof structure 105 and a fixed base 103, and the chassis assembly is watertightly connected to the screw rod 100 through the sealing and waterproof structure 105, the supporting chassis 102 and the fixed base 103; a locking member 104, which is used to lock the fixed base 103 at a preset position on the screw rod 100, so that the fixed base 103 is tightly connected to the supporting chassis 102.

[0034] The support and photovoltaic panel installation system of the embodiment of the present application, by arranging fixings, a supporting chassis, a fixed base, and a locking member on the screw rod, enables the supporting chassis to increase the contact area with the base surface, thereby enhancing the stabilizing effect of the fixed base abutting thereon, and further locks the fixed base by the locking member to be tightly connected with the supporting chassis, and through the mutual cooperation between the supporting chassis, the fixed base and the screw rod, the support can play the role of stabilizing the installation of the photovoltaic panel on the upper part of the base surface, and the supporting chassis and the fixed base, as well as the screw rod and the supporting chassis are sealed and connected by a sealing and waterproof structure, so that the support can be sealed and waterproofly connected to the base surface, effectively preventing the problem of water leakage.

[0035] In the embodiments of the present application, the base surface refers to the surface of the roof panel. Figure 1 As shown, the screw rod 100 is provided with a first end 100a and a second end 100b opposite to each other along its length direction, wherein the first end 100a and the second end 100b can be connected as a whole, or can be divided into an upper and a lower part. In the upper and lower two-part solution, the first end 100a is the lower part, and the second end 100b is the upper part, and the first end 100a and the second end 100b can be respectively screwed into the threaded holes of the fixed base 103.

[0036] In the embodiment of the present application, the support chassis 102 is provided so that the support can have a larger contact area with the base surface of the roof panel. When the fixed base 103 is abutted against the support chassis 102, the support is integrally connected with the roof panel, so that the photovoltaic panel can be more stably arranged. While playing the role of more stably supporting the photovoltaic panel on the upper part of the second end connector of the screw rod, it can also utilize the gravity and structural strength of the roof panel to enhance the pulling value between the photovoltaic panel and the support and the roof panel, effectively preventing the risk of being blown away by the wind.

[0037] like Figure 1 and 2 As shown, the support chassis 102 can be sleeved on the screw rod 100. The adjustable spacing between the chassis assembly and the fixing member 101 means that the distance between the fixing member 101 and the support chassis 102 arranged on the roof panel can be appropriately adjusted along the length direction of the screw rod 100 according to the thickness of the roof panel or the requirements during installation, thereby achieving an adjustable spacing between the chassis assembly and the fixing member.

[0038] In the embodiment of the present application, the spacing between the chassis assembly and the fixing member 101 is adjustable, so that the screw rod 100 can pass through the roof panel and clamp the roof panel between the supporting chassis 102 and the fixing member 101. The spacing between the chassis assembly and the fixing member 101 is equal to or less than the thickness of the roof panel, so that the support and the roof panel are tightly connected. The spacing is less than the thickness of the roof panel, that is, the difference between the spacing and the thickness of the roof panel does not exceed 0.5%, 1%, 2%, 3% or 5% of the thickness of the roof panel, so as to avoid the support from excessively squeezing the roof panel and causing damage to the roof panel.

[0039] In some embodiments of the present application, Figure 1 and 2 As shown, the support chassis 102 is formed around the screw rod 100 and extends radially outwardly along the screw rod 100, and a hole is provided in the middle for the screw rod 100 to pass through (the hole is not shown in the drawings), that is, the support chassis forms an annular disk to increase the contact area between the support chassis 102 and the roof panel, thereby more stably supporting the fixed base 103 on the upper part of the support chassis 102.

[0040] In some embodiments of the present application, the supporting chassis 102 and the fixing base 103 are independently made of metal or engineering plastic, and each of them can be made of corresponding materials according to specific application scenarios.

[0041] In some embodiments of the present application, one end of the fixed base 103 connected to the supporting chassis 102 is provided with a crimping portion 103a extending radially outward, and this end can be defined as the first end of the fixed base. The crimping portion 103a has a certain thickness along the length direction of the fixed base. The setting of the crimping portion 103a enables the fixed base 103 to adapt to the shape of the supporting chassis 102, increases the contact area between the fixed base 103 and the supporting chassis 102, and enables the fixed base 103 to be supported by the supporting chassis 103, thereby preventing the support from being easily pulled out of the roof panel by the wind. At the same time, the crimping portion 103a of the supporting chassis 102 and the fixed base 103 also enables the support to evenly disperse the force of the photovoltaic panel set on its top due to gravity applied to the roof panel on the roof panel, forming a stable support and protection system.

[0042] In other embodiments of the present application, the fixed base 103 is provided with a protrusion 103c protruding outward from the lower surface of the fixed base 103 along the length direction of the fixed base 103 at the lower part of one end of the crimping portion 103a, so as to tightly crimp the sealing and waterproof structure 105 at the upper part of the through hole of the supporting chassis 102, and utilize the structural force between the fixed base 103 and the supporting chassis 102 to achieve a sealing and waterproof effect, thereby improving the sealing and waterproof effect of the support itself.

[0043] In some embodiments of the present application, the fixed base 103 is provided with a through hole 103b for accommodating the screw rod 100 to pass through or a threaded hole 103b threadedly connected to the screw rod 100, so that the fixed base 103 can move on the screw rod 100 and then be locked on the supporting chassis 102 by the locking member 104. The through hole 103b or the threaded hole 103b is arranged in the middle of the fixed base 103 along the length direction of the fixed base 103 to form a cavity for accommodating the screw rod 100. By partially accommodating the screw rod 100 in the cavity, the screw rod 100 is supported along the length direction of the fixed base 103 to prevent the screw rod from bending or deflecting to both sides.

[0044] In the embodiment of the present application, the watertight connection refers to a sealed and waterproof connection. The sealed waterproof structure 105 can seal and waterproof the gap between the supporting chassis 102 and the fixed base 103, as well as the connection between the screw rod and the supporting chassis, to prevent water from flowing downward through the gap between these parts of the structure and entering the interior of the roof.

[0045] In some embodiments of the present application, Figure 2 As shown, the sealing waterproof structure 105 connects the connection between the supporting chassis 102 and the fixed base 103, and the connection between the screw rod 100 and the supporting chassis 102 and the fixed base 103 in a watertight manner, so as to play the role of sealing and waterproofing the screw rod and the supporting chassis, and the supporting chassis and the fixed base. Furthermore, the sealing waterproof structure 105 is coated on the outer peripheral surface of the supporting chassis 102, that is, the sealing waterproof structure 105 wraps the supporting chassis 102 inside, and connects the gap between the supporting chassis 102 and the fixed base 103, the gap between the screw rod 100 and the supporting chassis 102, and the gap between the screw rod 100 and the fixed base 103 in a watertight manner, so as to improve the waterproof performance of the support itself. And the sealing waterproof structure 105 set at the lower part of the supporting chassis 102 can also be sealed and connected with the waterproof roll layer of the roof panel, further realizing the watertight connection between the roof panel and the support, and preventing external water from leaking into the room along the gap between the support and the roof panel. The sealing and waterproof structures provided on the outer peripheral surface of the supporting chassis 102 can form a sealing and waterproof structure of the support itself to improve the sealing and waterproof performance.

[0046] In some embodiments of the present application, the sealing waterproof structure 105 includes a waterproof roll 105a coated on the upper surface and the lower surface of the support chassis 102. On the one hand, the waterproof roll coated on the upper surface of the support chassis 102 can enhance the sealing and waterproof performance between the fixed base 103 and the support chassis 102. On the other hand, the waterproof roll 105a coated on the lower surface of the support chassis 102 can further enhance the sealing and waterproof performance between the fixed base 103 and the support chassis 102, and the waterproof roll 105a on the lower surface of the support chassis 102 can also be welded to the waterproof layer of the roofing board to form an integral waterproof layer, enhance the sealing and waterproof performance, and prevent external water from entering the roof panel or the room through the gap between the roof panel and the support. The waterproof roll 105a coated on the outer peripheral surface of the support chassis 102 can form a sealing and waterproof structure of the support itself to improve the sealing and waterproof performance.

[0047] In some embodiments of the present application, the waterproof coiled material 105a can be formed by spraying a coating for forming the waterproof coiled material during installation, or directly using a flexible waterproof coiled material for sealing and waterproof connection, or a combination of the two. Or adhesive bonding is used. Exemplarily, the watertight connection between the screw rod 100 and the supporting chassis 102 and the fixed base 103 can be performed in the form of a coiled material plus a sprayed coating.

[0048] In some embodiments of the present application, the fixing member 101 is a rivet nut.

[0049] In some embodiments of the present application, the support further includes a reinforcing connector 106, and the reinforcing connector 106 has a first end 106a and a second end 106b at both ends along its length direction, and the cross-sectional area of ​​the first end 106a is smaller than the cross-sectional area of ​​the second end 106b; the second end 106b is connected to the fixing member 101, and the first end 106a is connected to the structural plate 2. The cross-sectional area of ​​the second end 106b is larger than the cross-sectional area of ​​the first end 106a, which can increase the contact area with the fixing member 101, so that the reinforcing connector 106 can enhance the connection strength between the fixing member 101 and the structural plate 2.

[0050] In some embodiments of the present application, the support further includes a connecting member 107, which is disposed at a second end 100b of the screw rod 100 opposite to the fixing member 101, and is used to install a photovoltaic panel. Figure 1 and 2 As shown, the connector 107 is disposed on the upper portion of the screw rod 100. For example, a mounting seat or a guide rail bracket may be disposed on the connector 107, and then the photovoltaic panel is mounted on the mounting seat or the guide rail bracket to obtain a photovoltaic panel mounted on the photovoltaic panel mounting system.

[0051] In some embodiments of the present application, the support further includes a fastener 108, which is sleeved on the screw rod 100 and located between the locking member 104 and the connector 107. The fastener 108 is used to further fix the connector 107 to the photovoltaic panel when the connector 107 connects the photovoltaic panel, that is, to fasten the connector 107.

[0052] In a second aspect, the embodiments of the present application also provide a photovoltaic panel installation system, such as Figure 2 As shown, it includes: the above-mentioned support; a roof panel, the roof panel at least includes a structural plate 2, and a waterproof membrane layer 5 arranged on one side of the structural plate 2; the first end 100a of the screw rod 100 passes through the waterproof membrane layer 5, the structural plate 2 and is connected with the fixing member 101 in sequence, the sealing waterproof structure 105 connects the supporting chassis 102, the fixed base 103 and the waterproof membrane layer 5 with the screw rod 100 in a watertight manner, and the locking member 104 locks the fixed base 103 at a preset position on the screw rod 100, so that the fixed base 103 is tightly connected to the supporting chassis 102.

[0053] The photovoltaic panel installation system of the embodiment of the present application connects the above-mentioned support and the roof panel as a whole, and utilizes the gravity and structural strength of the roof panel to make the photovoltaic panel installation system have strong wind resistance after the photovoltaic panel is installed, and its wind resistance is 3 to 4 times that of the traditional clamp. At the same time, the waterproof coiled material layer 5 can be connected to the sealed waterproof structure 105, so that the support and the roof panel can have better sealing and waterproof performance.

[0054] In an embodiment of the present application, the locking member 104 locks the fixed base 103 to the preset position on the screw rod 100, which means that after the first end 100a of the screw rod 100 passes through the roof panel, the reinforcing connector 106 and is connected to the reinforcing connector 106 and the fixing member 101, or is only connected to the fixing member 101, the chassis assembly is fixed to the upper part of the waterproof membrane layer 5 of the roof panel along the length direction of the screw rod 100 by the locking member 104. The preset position is the position where the locking member 104 fixes the fixed base 103 on the screw rod 100 to the upper part of the waterproof membrane layer 5 of the roof panel.

[0055] In some embodiments of the present application, the structural plate 2 includes a profiled portion 201 formed by protruding from the first surface to the second surface. The profiled portion 201 is used to connect with the fixing member 101 of the support so that the support is connected to the roof panel. The first surface refers to the surface of the structural plate 2 facing away from the vapor barrier 3, and the second surface refers to the surface of the structural plate 2 on the side connected to the vapor barrier 3.

[0056] In an embodiment of the present application, the structural plate 2 may be made of metal, such as a steel plate or an aluminum plate, or an alloy material plate, such as an aluminum alloy plate. Or the structural plate 2 may be a plastic steel tile or engineering plastic material with a certain structural strength. The waterproof roll layer 5 may be a TPO polymer waterproof roll. The TPO polymer waterproof roll has excellent weather resistance and can be directly exposed for more than 25 years, thereby ensuring that it matches the 25-year life of the photovoltaic module. The surface of the TPO polymer waterproof roll is white, which can reflect most of the sunlight and reduce heat conduction to a certain extent. The waterproof roll layer 5 and the waterproof roll 105a may be made of the same or different materials. Using the same material can better weld the waterproof roll layer 5 and the waterproof roll 105a to form an integral waterproof layer.

[0057] In some embodiments of the present application, the roof panel also includes: a vapor barrier layer 3, arranged on the first side 200 of the structural panel 2; a thermal insulation layer 4, arranged on the side of the vapor barrier layer 3 facing away from the structural panel 2; a waterproof membrane layer 5 is arranged on the side of the thermal insulation layer 4 facing away from the vapor barrier layer 3; the first end 100a of the screw rod 100 passes through the waterproof membrane layer 5, the thermal insulation layer 4, the vapor barrier layer 3, the structural panel 2 and is connected to the fixing member 101 in sequence, and the sealing waterproof structure 105 seals and connects the supporting chassis 102 with the waterproof membrane layer 5.

[0058] The photovoltaic panel installation system of the embodiment of the present application can make a complete set of vapor barrier layer, thermal insulation layer, and waterproof roll layer on the roof made of metal plate to form a roof panel, so that the photovoltaic panel installation system has better vapor barrier, thermal insulation, and waterproof functions, can block the external heat from entering the room to a certain extent, and can also ensure the indoor temperature, reduce energy consumption, and save more energy. The support is directly connected to the structural plate and the waterproof roll layer, or to the structural plate, vapor barrier layer, thermal insulation layer, and waterproof roll layer, so that the photovoltaic panel installation system has a higher pull-out value and better wind resistance. And the sealing waterproof structure of the support can be directly welded on the waterproof roll layer of the roof panel, that is, the sealing waterproof structure of the support can be directly welded to the waterproof roll layer, which can not only ensure that the connection between the support and the roof panel is watertight, but also form an integral waterproof layer with the support and the waterproof roll layer.

[0059] The photovoltaic panel mounting system of the embodiment of the present application is also suitable for side facade installation. The photovoltaic panel mounting system installed on the side facade requires the base layer to have strong structural strength to support the photovoltaic panel mounting system.

[0060] Optionally, in other embodiments of the present application, the roof panel may include a structural panel 2 and a waterproof membrane layer 5, and any one of a vapor barrier layer 3 and a thermal insulation layer 4. That is, the photovoltaic panel installation system of the embodiment of the present application is applicable to roof structures of different roof panels.
