Description

Technical Field

[0001] This application relates to the field of photovoltaic support technology, and more specifically, to a novel non-perforated support. Background Technology

[0002] The use of membrane-coated metal roofing tiles is becoming increasingly widespread in building materials, photovoltaic roofing systems, and roof waterproofing. However, due to the limitations of installation conditions, traditional clamp-fixing methods used for ordinary steel roofs are unsuitable. One method for installing photovoltaic systems on membrane-coated metal roofing tiles is to install vertical supports, anchoring them to the inner corrugated steel sheet or purlins, and then fixing the photovoltaic system to the supports. However, this method requires penetrating the waterproof membrane layer, damaging the original waterproof structure of the roof, increasing repair costs, and making the construction process complex and cumbersome. Another method is to install non-perforated supports fixed at the corrugations. However, when the photovoltaic system bears a load, concentrated forces are generated at the corrugations of the roof tiles connected to the supports, easily leading to damage and significant deformation of the roof tiles, affecting the safety and service life of the roof structure. Therefore, there is an urgent need for a new type of support that can guarantee waterproof performance, structural stability, and easy installation.

[0003] Therefore, this application proposes a novel non-perforated support to solve the aforementioned problems. Utility Model Content

[0004] To address the aforementioned issues, this application provides a novel non-perforated support.

[0005] The novel non-perforated support provided in this application adopts the following technical solution:

[0006] A novel non-perforated support includes:

[0007] The support body includes a U-shaped connector and a wave crest support arranged in a V-shape below the connector;

[0008] The top of the connector has a waist-shaped hole;

[0009] The crest support is fitted and covers the upper surface of the crest of the membrane metal tile roof, and the crest support and the crest surface are connected by hot air welding.

[0010] Furthermore, the middle sections of both sides of the corrugated support are bidirectionally convex outwards, and the outer surfaces of both sides of the corrugated support are fitted with skirts by rivets. The skirts are attached to the outer surfaces of the corrugated support, and the skirts have an obtuse angle structure and are horizontally attached to the film-coated metal tile roof. The part of the rivet that penetrates the support is located within the inner convex deformation range.

[0011] The above technical solutions enable the skirt to better fit the outer surface of the corrugated support, forming an obtuse angle structure and horizontally fitting the skirt of the film-coated metal tile roof. This further increases the contact area with the roof, disperses the load on the support, and avoids excessive local stress. The outward convex deformation design can limit and protect the rivets during installation, preventing them from loosening, enhancing the firmness of the connection between the support and the roof, and improving the durability and safety of the entire support system.

[0012] Furthermore, the skirt is also provided with a stainless steel washer that fits its outer surface, and the size of the washer is equal to the overlapping part of the skirt and the corrugated support; the rivet passes through the stainless steel washer, the skirt and the corrugated support in sequence.

[0013] The above technical solutions enhance the structural strength of the skirt, prevent damage to the skirt during rivet installation and use, and extend the service life of the skirt. On the other hand, the stainless steel gasket has good corrosion resistance, which can effectively resist external environmental erosion, protect the rivet connection parts, avoid loosening of the connection due to corrosion, and ensure that the connection between the support and the roof remains stable, further improving the waterproof performance and overall stability of the non-perforated support.

[0014] Furthermore, the skirt edge is made of the same waterproof material as the surface coating of the coated metal tile.

[0015] Through the above technical solution, the skirt uses the same waterproof material as the surface membrane of the membrane-coated metal tile, which makes the skirt and the roof highly matched in terms of material and waterproof performance. During the hot air welding process, the two can better integrate into one, forming a continuous and complete waterproof system. The seamless connection reduces the risk of leakage. The same material has consistent performance under environmental changes such as thermal expansion and contraction, avoiding gaps caused by inconsistent deformation due to material differences. This ensures the long-term waterproof reliability of the roof and improves the waterproof effect and environmental adaptability of the entire non-perforated support system.

[0016] Furthermore, the connector and the wave crest support are an integral structure, and the material includes aluminum alloy.

[0017] Through the above technical solutions, the integrated structure reduces the connection links between components, lowers the risk of loosening and leakage caused by loose connections, and improves the overall stability and reliability of the support. The aluminum alloy material is lightweight, high-strength, and corrosion-resistant, which reduces the weight of the support itself and the additional load on the roof. At the same time, the high strength ensures that it can effectively transfer the load, the corrosion resistance extends the service life of the support, reduces maintenance costs, and the aluminum alloy material is relatively easy to process, which simplifies the manufacturing process and reduces production costs.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] (1) The non-perforation design and the use of hot air welding to connect the corrugated support with the roof and skirt using the same waterproof material ensure the integrity of the roof waterproof layer from multiple aspects, eliminate the risk of leakage, and greatly improve the roof waterproof performance compared with the traditional perforation installation method. It provides more reliable waterproof protection for the interior of the building and reduces various maintenance and loss costs caused by leakage.

[0020] (2) The figure-eight shaped crest support can evenly distribute the load to the crest of the film-coated metal tile. Because the crest structure has strong resistance to bending deformation, it can effectively avoid damage and large deformation of the roof tiles. Attached Figure Description

[0028] Example:

[0029] The following is in conjunction with the appendix Figure 1 -3 provides further detailed description of this application.

[0030] This application discloses a novel non-perforated support, comprising:

[0031] The support body includes a U-shaped connector 1 and a wave crest support 2 located below the connector 1 and arranged in a V-shape;

[0032] The top of connector 1 has a waist-shaped hole;

[0033] The corrugated support 2 is attached to and covers the upper surface of the corrugation of the membrane metal tile roof, and the corrugated support 2 and the corrugated surface are connected by hot air welding.

[0034] See Figure 1 , Figure 2 and Figure 3 The corrugated support 2 has bidirectional outward convex deformation on both sides of its middle section. Skirts 3 are installed on the outer surfaces of both sides of the corrugated support 2 via rivets 5. The skirts 3 fit against the outer surface of the corrugated support 2, have an obtuse angle structure, and are horizontally attached to the film-coated metal roof. The portion of the rivet 5 penetrating the support is located within the inner outward convex deformation range. This allows the skirt 3 to better fit against the outer surface of the corrugated support 2. The obtuse angle structure and horizontal attachment of the skirt 3 to the film-coated metal roof further increase the contact area with the roof, dispersing the load on the support and preventing excessive local stress. The outward convex deformation design also provides some restraint and protection for the rivets 5 during installation, preventing them from loosening, enhancing the firmness of the connection between the support and the roof, and improving the durability and safety of the entire support system.

[0035] See Figure 1 , Figure 2 and Figure 3The skirt 3 is also equipped with a stainless steel gasket 4 that fits its outer surface. The size of the gasket is equal to the overlapping part of the skirt 3 and the corrugated support 2. The rivet 5 passes through the stainless steel gasket 4, the skirt 3 and the corrugated support 2 in sequence. This enhances the structural strength of the skirt 3, prevents the rivet 5 from damaging the skirt 3 during installation and use, and extends the service life of the skirt 3. On the other hand, the stainless steel gasket 4 has good corrosion resistance and can effectively resist external environmental erosion, protect the connection parts of the rivet 5, avoid loosening of the connection due to corrosion, and ensure that the connection between the support and the roof remains stable. This further improves the waterproof performance and overall stability of the non-perforated support.

[0036] See Figure 1 , Figure 2 and Figure 3 The skirt 3 uses the same waterproof material as the surface membrane of the coated metal tile; the use of the same waterproof material as the surface membrane of the coated metal tile makes the skirt 3 highly compatible with the roof in terms of material and waterproof performance; during the hot air welding process, the two can better integrate into one, forming a continuous and complete waterproof system, and the seamless connection reduces the risk of leakage; the same material has consistent performance under environmental changes such as thermal expansion and contraction, avoiding gaps caused by inconsistent deformation due to material differences, thus ensuring the long-term waterproof reliability of the roof and improving the waterproof effect and environmental adaptability of the entire non-perforated support system.

[0037] See Figure 1 , Figure 2 and Figure 3 The connector 1 and the corrugated support 2 are an integrated structure made of aluminum alloy. The integrated structure reduces the number of connection links between components, reducing the risk of loosening and leakage caused by loose connections, and improving the overall stability and reliability of the support. Aluminum alloy is lightweight, high-strength, and corrosion-resistant, which reduces the weight of the support itself and the additional load on the roof. At the same time, its high strength ensures that it can effectively transfer the load, and its corrosion resistance extends the service life of the support and reduces maintenance costs. In addition, aluminum alloy is relatively easy to process, which simplifies the manufacturing process and reduces production costs.

[0038] The implementation principle of a novel non-perforated support in this application embodiment is as follows: the corrugated support 2 is tightly attached to the corrugation of the film-coated metal tile roof by hot air welding, and a firm connection is achieved by welding to avoid perforation.

[0039] The skirts 3 on both sides of the corrugated support 2 are connected to the corrugated support 2 by rivets 5. The skirts 3 are in contact with the outer surface of the corrugated support 2 and the horizontal plane is in contact with the roof, which further enhances the connection stability and sealing. When loads such as photovoltaic systems are applied to the support, the V-shaped corrugated support 2 can evenly distribute and transfer the load to the corrugations of the coated metal tile. Since the corrugated structure has a strong resistance to bending deformation, it can effectively avoid damage to the roof tiles and large deformation.

[0040] All skirt edges 3 use the same waterproof material as the surface layer of the membrane metal tile (such as TPO, PVC and other polymer rolls) to ensure that the material is integrated after welding, with high bonding strength and consistent long-term weather resistance; in addition, the skirt edges 3 are not only welded to the corrugated support 2, but their horizontal part is also welded to the roof base layer to form a "surface-to-surface" connection. Compared with the traditional "point" fixing (such as rivets 5), it can distribute the load and enhance the wind uplift resistance.

[0041] The weld seam between the skirt 3 and the support overlaps with the weld seam between the support and the crest, forming two waterproof barriers. Even if there are minor defects in the local weld seam, the other weld seam can still prevent water penetration, thus improving the waterproof reliability of the system.

[0042] Hot air welding is a process in which hot air is sprayed onto the surface of the polymer material to be joined (such as the waterproof membrane with the same material as the surface layer of the coated metal tile in this patent) using a special hot air welding equipment, causing it to partially melt and applying a certain pressure to make the two materials bond tightly together to form a strong connection. The application of hot air welding does not require drilling or penetrating the roof, thus avoiding damage to the original waterproof layer and eliminating the risk of leakage at the source.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
