Description

Technical Field

[0001] This invention belongs to the field of photovoltaic installation technology, and specifically relates to a photovoltaic panel bracket for connecting to a metal roof. Background Technology

[0002] With the continuous development of the photovoltaic industry, the cost of solar power generation is showing a significant downward trend, making photovoltaic power generation a clean energy alternative with great development potential. The installation site for photovoltaic modules is usually selected on building structures such as rooftops that receive ample direct sunlight and are not easily shaded, with rooftops being the mainstream installation location for building-integrated photovoltaic (BIPV) systems. Compared to building exterior walls, rooftops offer advantages such as less shading, easier construction, and lower maintenance costs.

[0003] In current installation projects of photovoltaic systems on metal roofs, the mainstream connection methods have significant technical defects: First, some projects use welding connections. Although this method can meet the structural strength requirements of the photovoltaic system, it has drawbacks such as long construction period, high labor costs, and high overall cost. Furthermore, welding quality is easily affected by the operator's skills and environmental factors such as temperature and humidity, making it difficult to effectively guarantee the quality stability of the connection nodes. Welding operations can also damage the anti-corrosion coating of the metal roof, inducing the risk of localized rust. Second, some projects connect the photovoltaic system to the main structural components by adding purlins, and then use clamps to fix the photovoltaic system to the new purlins. This solution also suffers from cumbersome construction procedures, long construction periods, and high project costs. Moreover, the added purlins significantly increase the additional load on the roof, posing a potential impact on the structural safety of the main building. Summary of the Invention

[0004] In response to one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a photovoltaic panel bracket for connecting to a metal roof, which can realize a fast and reliable connection between the photovoltaic panel and the metal roof, and ensure the installation stability and service life of the photovoltaic system.

[0005] To achieve the above objectives, the present invention provides a photovoltaic panel support for connection with a metal roof, comprising a support rod, an upper steel plate, and a lower steel plate; The upper steel plate and the lower steel plate are arranged at intervals relative to each other on the support rod along the height direction of the support rod. The upper steel plate is sleeved on the outer peripheral wall of the support rod, and the lower steel plate is fixedly connected to the bottom end face of the support rod. The support rod, the upper steel plate and the lower steel plate are an integrated rigid structure. The upper steel plate is detachably connected to the metal roof panel through multiple first connecting components, and the lower steel plate is detachably connected to the roof load-bearing components through multiple second connecting components.

[0006] As a further improvement of the present invention, a sealing ring is provided between the upper steel plate and the metal roof panel.

[0007] As a further improvement of the present invention, the projection of the upper steel plate along the height direction of the support rod completely covers the projection of the lower steel plate along the height direction of the support rod.

[0008] As a further improvement of the present invention, both the upper steel plate and the lower steel plate are axisymmetric structures, and their axes of symmetry are both support rods.

[0009] As a further improvement of the present invention, both the upper steel plate and the lower steel plate are square in shape, and the side length of the upper steel plate is 1.5 to 2.5 times the side length of the lower steel plate.

[0010] As a further improvement of the present invention, a plurality of first connecting components are evenly distributed around the upper steel plate, and a plurality of second connecting components are evenly distributed around the lower steel plate.

[0011] As a further improvement of the present invention, the first connecting assembly includes a waterproof bolt and a waterproof nut, wherein the thread of the waterproof bolt passes through the bolt positioning holes of the metal roof panel and the upper steel plate in sequence and is then fastened to the waterproof nut.

[0012] As a further improvement of the present invention, the upper steel plate and / or the lower steel plate are galvanized steel plates.

[0013] As a further improvement of the present invention, the distance between the upper steel plate and the lower steel plate is 0.2~0.4m.

[0014] As a further improvement of the present invention, the thickness of the upper steel plate and / or the lower steel plate is 2~4mm.

[0015] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include: (1) The photovoltaic panel bracket for connecting to a metal roof of the present invention includes a support rod, an upper steel plate, and a lower steel plate; the upper steel plate and the lower steel plate are arranged at intervals relative to each other on the support rod along the height direction of the support rod, the upper steel plate is sleeved on the outer peripheral wall of the support rod, and the lower steel plate is fixedly connected to the bottom end face of the support rod, and the support rod, the upper steel plate, and the lower steel plate are an integrated rigid structure; the upper steel plate is detachably connected to the metal roof panel through multiple first connecting components, and the lower steel plate is detachably connected to the roof load-bearing components through multiple second connecting components. The photovoltaic panel bracket for connecting to a metal roof of the present invention is an integrated prefabricated rigid structure. On-site construction only requires fixing and assembling through multiple sets of connecting components, which simplifies the on-site construction process, can significantly shorten the construction period, and can avoid the quality fluctuation problems that are prone to occur in the welding process, thus ensuring the construction quality.

[0017] (2) The photovoltaic panel bracket of the present invention for connecting with a metal roof can effectively fill the gap between the upper steel plate and the metal roof panel by setting a sealing ring between the upper steel plate and the metal roof panel, thus blocking the rainwater infiltration path; and the waterproof bolts and waterproof nuts used in the first connecting component can also effectively block rainwater from penetrating into the house from the bolt positioning block.

[0018] (3) The photovoltaic panel bracket for connecting with a metal roof of the present invention improves the stress balance and overall rigidity of the photovoltaic panel bracket by setting the upper steel plate and the lower steel plate into an axisymmetric structure, with the axis of symmetry being the support rod, and by distributing multiple first connecting components around the upper steel plate and multiple second connecting components around the upper steel plate, thereby ensuring that the photovoltaic panel bracket will uniformly transfer the load to the roof stress components.

[0019] (4) The photovoltaic panel bracket of the present invention for connecting with metal roof only requires a small number of openings in the metal roof to complete the installation, greatly reducing the amount of renovation work and minimizing the impact of photovoltaic system installation on the structural stability and appearance integrity of the existing building. At the same time, the photovoltaic system load is directly transferred to the roof load-bearing components through the photovoltaic panel bracket, without relying on the roof itself for support, breaking through the limitation on the type of metal roof, and making the technical solution highly adaptable to metal roofs of different specifications and types.

[0027] Example: Please see Figures 1-3 In a preferred embodiment of the present invention, the photovoltaic panel support for connection to a metal roof includes a support rod 1, an upper steel plate 2, and a lower steel plate 3. The upper steel plate 2 and the lower steel plate 3 are spaced apart relative to each other on the support rod 1 along its height direction. The upper steel plate 2 is sleeved on the outer peripheral wall of the support rod 1, and the lower steel plate 3 is fixedly connected to the bottom end face of the support rod 1. The support rod 1, upper steel plate 2, and lower steel plate 3 form an integrated prefabricated rigid structure. The upper steel plate 2 is detachably connected to the metal roof panel 7 via multiple first connecting components 4, and the lower steel plate 3 is detachably connected to the roof load-bearing component 8 via multiple second connecting components 5. Preferably, the support rod 1 can be made of high-strength aluminum alloy, possessing lightweight and high-strength characteristics, and its top supports the photovoltaic panel or the frame of the photovoltaic panel. The roof load-bearing component 8 can be a purlin, load-bearing joist, etc.

[0028] In this embodiment, the support rod 1, upper steel plate 2, and lower steel plate 3 are pre-processed using a standardized process. Then, the three components are fully welded to form a rigid photovoltaic panel bracket. On-site construction only requires multiple sets of connecting components for fixed assembly. Precision factory production ensures the processing accuracy and quality stability of each component of the photovoltaic panel bracket, thereby guaranteeing the overall project quality. Furthermore, the factory can customize components of corresponding sizes and specifications based on the structural characteristics, load requirements, and installation scenarios of different buildings, giving this photovoltaic panel bracket broad architectural adaptability.

[0029] Specifically, the installation process of the photovoltaic panel bracket on the metal roof is as follows: installation holes are opened at the preset installation positions of the roof panel, the lower steel plate 3 passes through the installation holes and abuts against the roof load-bearing component 8, while the upper steel plate 2 abuts against the metal roof panel 7. The upper steel plate 2 and the metal roof panel 7 are fixedly connected by multiple first connecting components 4, and the lower steel plate 3 and the roof load-bearing component 8 are fixedly connected by multiple second connecting components 5, so as to achieve a reliable connection between the photovoltaic panel bracket and the metal roof.

[0030] Preferably, a sealing ring 6 is provided between the upper steel plate 2 and the metal roof panel 7. The sealing ring is preferably made of EPDM rubber material. The compression rate of the sealing ring 6 is controlled at 30%~50%, which can effectively fill the gap between the upper steel plate 2 and the metal roof panel 7 and block the rainwater infiltration path.

[0031] In actual design, the spacing between the upper steel plate 2 and the lower steel plate 3 corresponds to the spacing between the metal roof panel 7 and the roof load-bearing member 8, so that when the lower steel plate 3 abuts against the roof load-bearing member 8, the upper steel plate 2 abuts against the metal roof panel 7.

[0032] Specifically, preferably, the distance between the upper steel plate 2 and the lower steel plate 3 is 0.2~0.4m. This distance ensures the stability of load transfer while providing sufficient space for construction operations. For example, the distance between the upper steel plate 2 and the lower steel plate 3 is 0.3m.

[0033] Furthermore, the thickness of the upper steel plate 2 and / or the lower steel plate 3 is preferably 2 to 4 mm. For example, the thickness of the upper steel plate 2 and / or the lower steel plate 3 is 3 mm.

[0034] Preferably, the upper steel plate 2 and / or the lower steel plate 3 are galvanized steel plates. The surface of the galvanized steel plate has a dense oxide protective film, which can effectively resist the corrosion of outdoor wind, rain, high humidity and salt spray environment, adapt to the outdoor service environment of the roof, and extend the service life of the support.

[0035] More preferably, the projection of the upper steel plate 2 along the height direction of the support rod 1 completely covers the projection of the lower steel plate 3 along the height direction of the support rod 1, so that the upper steel plate 2 can form a shielding and protection for the connection node of the lower steel plate 3.

[0036] Preferably, both the upper steel plate 2 and the lower steel plate 3 are axisymmetric structures, and the axis of symmetry is the support rod 1, which ensures that the support rod 1 can evenly transfer the load to the roof load-bearing components 8.

[0037] Preferably, both the upper steel plate 2 and the lower steel plate 3 are square in shape, with the side length of the upper steel plate 2 being 1.5 to 2.5 times the side length of the lower steel plate 3. In a specific preferred embodiment, the side length of the square upper steel plate 2 is 300 mm, the side length of the square lower steel plate 3 is 150 mm, and the portion of the upper steel plate 2 extending beyond the lower steel plate 3 is evenly distributed around the perimeter of the lower steel plate 3. The upper steel plate 2 and the lower steel plate 3 face each other directly, and their side lengths are parallel.

[0038] More preferably, multiple first connecting components 4 are evenly distributed around the upper steel plate 2, and multiple second connecting components 5 are evenly distributed around the upper steel plate 2, to ensure that each connecting component is subjected to relatively uniform force.

[0039] Preferably, the first connecting assembly 4 includes a waterproof bolt 41 and a waterproof nut 42. The thread of the waterproof bolt 41 passes through the bolt positioning holes of the metal roof panel 7 and the upper steel plate 2 in sequence and is then fastened to the waterproof nut 42. The first connecting assembly 4, using the waterproof bolt 41 and the waterproof nut 42, can effectively prevent rainwater from seeping into the house through the bolt positioning block.

[0040] Preferably, the second connecting component 5 includes bolts and nuts. The roof load-bearing component 8 and the lower steel plate 3 have corresponding bolt positioning holes. The bolt shank passes through the two bolt positioning holes and is then locked in place by the nut. Preferably, the second connecting component 5 can also use waterproof bolts and waterproof nuts.

[0041] For example, a sealing ring 421 is provided at the abutment end of the waterproof nut 42 and the upper steel plate 2 / lower steel plate 3, such as... Figure 3 As shown.

[0042] The installation process of the photovoltaic panel bracket for connecting to a metal roof is as follows: (1) Factory prefabrication: The support rod 1, the upper steel plate 2 and the lower steel plate 3 are processed according to the design dimensions and fixed into an integrated rigid structure by full welding process; (2) On-site positioning: Open the installation hole at the preset installation position of the metal roof, move the prefabricated bracket to the preset installation position of the metal roof, and adjust the level of the bracket after the lower steel plate 3 passes through the installation hole to ensure that the support rod 1 is perpendicular to the metal roof panel 7. (3) Upper layer fixing: A rubber sealing ring 6 is laid between the upper steel plate 2 and the metal roof panel 7. The screw of the waterproof bolt 41 is passed through the metal roof panel 7, the rubber sealing ring 6 and the upper steel plate 2 in sequence. The waterproof nut 42 is screwed on and tightened to the preset torque using a torque wrench. (4) Lower layer fixing: Pass the screw of the waterproof bolt through the lower steel plate 3 and the roof load-bearing component 8 in sequence, tighten the waterproof nut, and complete the fixed connection between the photovoltaic panel bracket and the metal roof.

[0043] In the above installation process, steps (3) and (4) are not sequential. After the photovoltaic panel bracket is installed on the metal roof, the photovoltaic panel can be installed on the top of the support rod to complete the installation of the entire photovoltaic system.

[0044] The photovoltaic panel bracket for connecting to a metal roof in this invention requires only a few openings in the metal roof to complete the installation, significantly reducing the amount of renovation work and minimizing the impact of adding a photovoltaic system on the structural stability and aesthetic integrity of the existing building. At the same time, the photovoltaic system load is directly transferred to the roof load-bearing components through the photovoltaic panel bracket, without relying on the roof itself for support, breaking through the limitations of metal roof types and making the technical solution highly adaptable to metal roofs of different specifications and types.

[0045] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
