Description

Technical Field

[0001] The invention belongs to the field of photovoltaic component bracket installation, and relates to a lossless installation structure and method of a photovoltaic component bracket on a goose-shaped tile roof. Background Art

[0002] With the continued growth of global energy demand and the increasing emphasis on renewable energy, the development and utilization of solar energy, as a clean, renewable energy source, has garnered widespread attention. Distributed photovoltaic systems are particularly popular in the solar energy sector due to their flexible installation on various building rooftops, enabling localized power generation and use. Among these, the goose-shaped tile roof, with its unique shape and drainage capabilities, has gained widespread adoption in many regions, particularly those with traditional architectural styles.

[0003] However, installing a photovoltaic system on a goose-shaped tile roof presents numerous technical challenges. Currently, photovoltaic bracket installation methods for conventional concrete flat roofs and color-coated steel tile roofs are relatively mature, forming a stable and reliable technical system. However, due to the unique structural characteristics of goose-shaped tile roofs, the uneven roof surface makes it impossible to use the counterweight and bracket installation method similar to that used on concrete flat roofs.

[0004] In existing technology, most photovoltaic mounts on goose-shaped tile roofs are installed using rebar embedding. Specifically, this method involves drilling holes in the goose-shaped tiles, inserting rebar, and then applying adhesives and other materials to secure the mounts. However, this method presents a number of significant issues and drawbacks.

[0005] First, from a structural strength perspective, goose-shaped tiles are typically thin, typically only about 4cm. During rebar planting, due to the limited thickness of the tiles, the embedded rebar cannot meet sufficient pullout resistance requirements. This means that under the long-term weight of the PV panels and natural forces such as wind and snow, the rebar may become loose or even pull out, seriously affecting the stability and safety of the PV rack.

[0006] Secondly, during construction, drilling holes for rebar installation can easily damage the goose-shaped tiles. Due to their insufficient thickness, drilling holes can easily penetrate the tiles, allowing rainwater and other liquids to seep into the roof, causing leaks. A leak in the roof not only damages the building's internal structure and finishes but can also affect the normal operation of the photovoltaic system, shortening its service life.

[0007] Furthermore, the drilling process for rebar installation damages the integrity of the goose-shaped tile surface. Even if sealing is performed after construction is completed, it is difficult to guarantee that the original sealing performance of the tile will be fully restored. Over time, the sealed area may age and crack, leading to the continued risk of water leakage.

[0008] In summary, the existing rebar installation method has many drawbacks in the installation of photovoltaic brackets on goose-shaped tile roofs, and cannot meet the requirements of safe, reliable, and durable installation. Therefore, the development of a structure and method for non-destructive installation of photovoltaic brackets suitable for goose-shaped tile roofs has become a technical problem that needs to be solved in the current photovoltaic field. Summary of the Invention

[0009] In view of this, the object of the present invention is to provide a lossless installation structure and method for a photovoltaic module bracket on a goose-shaped tile roof, so as to solve the above-mentioned problems.

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lossless installation structure of a photovoltaic component bracket on a goose-shaped tile roof, comprising a plurality of U-shaped bolts arranged through the water holes of the goose-shaped tile roof, an adjustable base connected to the top of the U-shaped bolts, and a column arranged on the adjustable base, wherein a photovoltaic bracket assembly is installed on the top of the column through an inclined beam; the end of the U-shaped bolt is provided with a thread, and an end plate is horizontally connected between the two threaded rods at the top of the U-shaped bolt and fastened by a nut.

[0011] Optionally, a base is provided at the bottom of the adjustable base, which is connected to the end plate, and the base is provided with two strip mounting holes which are perpendicular to each other in length direction; an adjustable pillar is provided in the middle position of the base between the two strip mounting holes, and the pillar is provided with multiple fixing holes for fixing the pillars, and the bottom of the column is connected to the pillar fixing hole by a hexagon socket bolt assembly to achieve height adjustment.

[0012] Optionally, the U-shaped bolt is a special bolt, the U-shaped opening size of which is adapted to the aperture of the water hole of the goose-shaped tile, and the end of the bolt is provided with a thread for fastening with the adjustable base.

[0013] Optionally, the top of the column is connected to the inclined beam through a triangular connector, and a number of parallel purlins are fixedly installed on the upper part of the inclined beam. The purlins are spliced ​​by purlin connectors, and the photovoltaic module frame is fixed to the top through a pressing block and a diamond nut.

[0014] Optionally, diagonal braces are installed on the upper part of the column and the bottom of the diagonal beam respectively through triangular connectors.

[0015] Optionally, the connection points between the triangular connector and the inclined beam and the column are hinged connection points, and more than two oblong holes for fixed connection are provided at the bottom.

[0016] A method for non-destructive installation of a photovoltaic module support on a goose-shaped tile roof, using the above-mentioned non-destructive installation structure of a photovoltaic module support on a goose-shaped tile roof, includes the following steps:

[0017] S1, water hole positioning: measure the distribution of water holes on the goose-shaped tile and select water holes without structural cracks as fixed base points;

[0018] S2, U-bolt installation: Pass the U-bolt through the water hole from the bottom of the roof, and install the end plate between the two threaded rods of the U-bolt on the roof;

[0019] S3, column foot leveling: fit the adjustable base to the end plate, adjust the horizontal position through the strip mounting holes, and tighten the nuts after calibration;

[0020] S4, bracket assembly: hinge the diagonal beam to the top of the column through the triangular connector, tighten the oblong hole bolts after adjusting the diagonal support angle; fix the purlin to the top of the diagonal beam after splicing through the connector, and fix the photovoltaic bracket assembly with the pressure block and diamond nut.

[0021] Optionally, the size of the U-bolt opening and the end plate is determined according to the size of the water hole on site.

[0022] The beneficial effects of the present invention are:

[0023] 1. Achieve non-destructive installation and safeguard roof integrity: This structure and method cleverly utilizes the pre-set water holes in the goose-shaped tiles as a fixed base point. Special U-shaped bolts pass through the water holes to secure the column base, eliminating the need to drill holes in the tiles or damage the original structure. Compared to traditional rebar planting methods that require drilling through the tiles and risk leaks, this solution fundamentally avoids physical damage to the roof during construction, ensuring the integrity and waterproof performance of the goose-shaped tile roof and extending the roof's service life.

[0024] 2. Eliminate water leakage hazards and improve system safety: Traditional rebar installation damages the finished tile surface due to drilling, and post-installation sealing is difficult to ensure, posing a long-term risk of rainwater infiltration. This solution, through a non-destructive fixing design, completely avoids water leakage caused by installation operations, reducing roof repair costs. It also avoids secondary hazards such as photovoltaic module short circuits and bracket corrosion caused by water leakage, significantly improving the operational safety and reliability of the entire photovoltaic system.

[0025] 3. Adapts to roof fluctuations and ensures structural stability: The adjustable base, through strip mounting holes, is mated with U-bolt end plates, allowing horizontal adjustment to accommodate the irregular undulations of a goose-shaped tile roof. The bottom of the column is connected to the hexagon socket bolt assembly via an adjustable support, allowing fine-tuning of the height. This dual adjustment mechanism ensures the horizontality and verticality of the photovoltaic bracket on complex roofs, allowing the entire structure to evenly withstand external forces such as wind loads and snow pressure, and avoiding deformation or damage to the bracket due to localized stress concentration.

[0026] 4. Convenient and efficient installation, reducing overall costs: This solution utilizes a modular design, with pre-assembled components such as U-bolts, adjustable bases, and columns. On-site installation requires only simple operations such as locating the water holes, tightening the bolts, and adjusting the angle. Compared to the rebar planting process, which requires a waiting period for the adhesive to cure, this method significantly shortens the construction cycle and reduces labor costs. Furthermore, since no additional waterproofing or subsequent maintenance is required, the overall lifecycle cost is optimized.

[0027] 5. Strong compatibility, expanding application scenarios: The U-shaped opening size of the custom U-bolt can be customized to the water hole diameter of goose-shaped tiles from different manufacturers. The base's strip mounting holes and adjustable support design also adapt to various roof slopes and tile arrangements. In addition, the spliced ​​structure of the diagonal beams and purlins supports horizontal or vertical layout of photovoltaic panels, meeting different power requirements and roof space limitations, and has a wide range of applicability.

[0028] 6. Durable structure, extending system lifecycle: All metal components are treated with anti-corrosion treatment (such as hot-dip galvanizing). The hinged design of the triangular connectors, diagonal beams, and columns reduces fatigue damage during stress transfer. Combined with the protection of the roof structure through non-destructive installation, the entire photovoltaic system can maintain stable performance throughout its 25-year design lifespan, reducing the risk of premature replacement due to loose brackets or roof damage.
