Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module bracket installation, and relates to a non-destructive installation structure for photovoltaic module brackets on a scalloped tile roof. Background Technology

[0002] With the continued growth of global energy demand and the increasing emphasis on renewable energy, solar energy, as a clean and renewable energy source, has received widespread attention for its development and utilization. In the field of solar energy utilization, distributed photovoltaic (PV) systems are highly favored due to their flexibility in installation on various building rooftops, enabling local power generation and consumption. Among these, the goose-shaped tile roof, with its unique shape and drainage function, has been widely used in many regions, especially in areas with traditional architectural styles.

[0003] However, installing photovoltaic systems on gable roofs presents numerous technical challenges. Currently, the installation methods for photovoltaic brackets on conventional flat concrete roofs and corrugated steel roofs are relatively mature, forming a stable and reliable technical system. However, for gable roofs, due to their unique structural characteristics—an uneven surface—the installation method using counterweights and brackets, similar to that used on flat concrete roofs, cannot be adopted.

[0004] In current technical practices, the installation of photovoltaic (PV) brackets for gabion roofs mostly employs the method of rebar anchoring. Specifically, this method involves drilling holes in the gabion tiles, inserting rebar, and using adhesives to secure the PV bracket. However, this installation method has a series of obvious problems and drawbacks.

[0005] Firstly, from a structural strength perspective, the thickness of shaped roof tiles is typically quite thin, generally only about 4cm. During the rebar installation process, due to the limited thickness of the tiles, the inserted rebar cannot meet sufficient pull-out resistance requirements. This means that under long-term stress from the weight of the photovoltaic modules and natural forces such as wind and snow, the rebar may loosen or even be pulled out, severely impacting the stability and safety of the photovoltaic support system.

[0006] Secondly, the drilling process during rebar installation can easily damage the roof tiles. Because the tiles are not thick enough, drilling can easily puncture them, allowing rainwater and other liquids to seep into the roof, causing leaks. Once a roof leaks, it not only damages the building's internal structure and decoration but may also affect the normal operation of the photovoltaic system and shorten its lifespan.

[0007] Furthermore, the drilling process for installing reinforcing bars damages the integrity of the roof tiles. Even after sealing is completed, it's difficult to guarantee a complete restoration of the tiles' original sealing performance. Over time, the sealed areas may age, crack, and continue to pose a risk of leakage.

[0008] In summary, existing rebar installation methods have many drawbacks in the installation of photovoltaic (PV) brackets on scalloped tile roofs, failing to meet the requirements of safe, reliable, and durable installation. Therefore, developing a structure and method for non-destructive installation of PV brackets on scalloped tile roofs has become an urgent technical problem to be solved in the photovoltaic field. Utility Model Content

[0009] In view of this, the purpose of this utility model is to provide a non-destructive installation structure for photovoltaic module support on a scalloped tile roof, so as to solve the above-mentioned problems.

[0010] To achieve the above objectives, this utility model provides the following technical solution: a non-destructive installation structure for a photovoltaic module support on a scalloped tile roof, comprising multiple U-bolts passing through water holes in the scalloped tile roof, an adjustable base connected to the top of the U-bolts, and a column mounted on the adjustable base. The photovoltaic support assembly is mounted on the top of the column via an inclined beam. The U-bolts are threaded at their ends, and an end plate is laterally connected between the two threaded rods at the top of the U-bolts and secured with a nut.

[0011] Optionally, the adjustable base is provided with a base that connects to the end plate at the bottom. The base has two strip-shaped mounting holes that are perpendicular to each other in the length direction. An adjustable support column is provided in the middle of the base between the two strip-shaped mounting holes. The support column has multiple fixing holes for fixing the column. The bottom of the column is connected to the fixing holes of the support column through an internal hex bolt assembly to achieve height adjustment.

[0012] Optionally, the U-bolt is a special bolt with a U-shaped opening size adapted to the diameter of the water passage hole of the goose-shaped tile, and the bolt end is threaded for fastening connection with the adjustable base.

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

[0014] Optionally, diagonal bracing is installed on the upper part of the column and the bottom of the inclined beam via triangular connectors.

[0015] Optionally, the connection point between the triangular connector and the inclined beam and column is a hinged connection point, and the bottom is provided with two or more elongated holes for fixed connection.

[0016] Optionally, the opening and end plate dimensions of the U-bolts are determined based on the dimensions of the water passage holes on site.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Achieve non-destructive installation and ensure roof integrity: This structure and method cleverly utilizes the pre-installed drainage holes in the shaped roof tiles as fixing bases. Special U-bolts are passed through these holes to secure the column bases, eliminating the need for drilling holes in the tiles or damaging the original structure. Compared to traditional rebar installation methods that require drilling through the tiles and risk leakage, this solution fundamentally avoids physical damage to the roof during construction, ensuring the integrity and waterproofing performance of the shaped roof tiles and extending the roof's lifespan.

[0019] 2. Eliminate leakage risks and enhance system safety: Traditional rebar installation damages the finished surface of the roof tiles due to drilling, and the sealing effect after construction is difficult to guarantee, resulting in a long-term risk of rainwater seepage. This solution, through a non-destructive fixing design, completely avoids leakage problems caused by installation operations, reduces roof maintenance costs, and prevents secondary disasters such as short circuits in photovoltaic modules and corrosion of the brackets caused by leakage, significantly improving the operational safety and reliability of the entire photovoltaic system.

[0020] 3. Adapting to roof undulations and ensuring structural stability: The adjustable base, through strip mounting holes and U-bolt end plates, can be horizontally adjusted to adapt to the irregular undulations of the scalloped tile roof; the bottom of the column is connected to the adjustable support column and hexagonal bolt assembly for fine-tuning of height. This dual adjustment mechanism ensures the horizontal and vertical alignment of the photovoltaic support system on complex roofs, enabling the overall structure to evenly withstand external forces such as wind loads and snow pressure, avoiding deformation or damage to the support system caused by localized stress concentration.

[0021] 4. Convenient and efficient installation, reducing overall costs: This solution adopts a modular design, and components such as U-bolts, adjustable bases, and columns can be pre-assembled. On-site operations only require simple steps such as locating water passages, tightening bolts, and adjusting angles. Compared to the adhesive curing time required for rebar installation, this method significantly shortens the construction cycle and reduces labor costs. Furthermore, since no additional waterproofing treatment or subsequent maintenance is needed, the overall life-cycle cost is more favorable.

[0022] 5. Strong compatibility and expanded application scenarios: The U-shaped opening size of the specially designed U-bolts can be customized according to the drainage hole diameter of the slatted roof tiles from different manufacturers. The strip mounting holes and adjustable support design of the base also adapt to various roof slopes and tile arrangement methods. In addition, the splicing structure of the inclined beam and purlin supports the horizontal or vertical layout of photovoltaic modules, meeting different power requirements and roof space constraints, and has wide applicability.

[0023] 6. Durable structure, extending system lifespan: All metal components undergo anti-corrosion treatment (such as hot-dip galvanizing), and the hinged design of the triangular connectors with the inclined beams and columns reduces fatigue damage during stress transfer. Combined with non-destructive installation to protect the roof structure, the entire photovoltaic system can maintain stable performance within its 25-year design life, reducing the risk of premature replacement due to loose supports or roof damage.
