Description

Technical Field

[0001] This utility model relates to the field of photovoltaic maintenance walkway installation technology, and in particular to a fastening structure for a corrosion-resistant irregular-shaped maintenance walkway inside a photovoltaic array on a color steel tile roof. Background Technology

[0002] my country's modernization faces significant challenges in energy supply. To alleviate the energy shortage, we must advocate conservation throughout society and build a conservation-oriented society. Solar power, a clean energy source, meets the principle of local production and use, reducing secondary energy consumption and transmission issues.

[0003] Distributed photovoltaic (PV) projects, which have been developing rapidly, are widely popular due to their flexible installation, strong adaptability, and low investment threshold. Distributed PV projects installed on factory roofs, in particular, allow for localized use and self-sufficiency. However, since factory roofs are typically made of corrugated steel sheets, frequent foot traffic during installation and maintenance can reduce their lifespan and affect their corrosion resistance. This utility model, a non-standard maintenance walkway, is primarily designed for such projects to protect the integrity of the roof. Utility Model Content

[0004] In order to adapt to the current diversified development of photovoltaic projects and broaden the scope of project installation, this utility model designs a new type of fastening structure for anti-corrosion irregular-shaped maintenance walkway inside a rooftop photovoltaic array, based on actual project needs.

[0005] A fastening structure for a corrosion-resistant, irregularly shaped maintenance walkway inside a photovoltaic array on a corrugated steel roof, comprising the maintenance walkway, characterized in that: The corrosion-resistant, irregularly shaped maintenance walkway is internally reinforced with support plates to increase its service life and stability. The support plates are welded to the walkway, and high-strength anti-corrosion treatment is applied after welding to protect the walkway's corrosion resistance. The walkway is secured within the slots of the first and second C-type fasteners, with anti-slip threads provided in the C-type fastener grooves. Supporting partitions are also added internally to the walkway.

[0006] Furthermore, to better realize this utility model, a novel C-type fastener is designed according to the shape of the irregular maintenance walkway. The C-type fastener is characterized by added threads on both sides of the internal groove to prevent loosening, and it eliminates the need to drill holes or openings in the irregular maintenance walkway during tightening, ensuring the overall strength of the walkway remains intact. The corrosion-resistant irregular maintenance walkway has no holes; it is secured by clamping the first and second C-type fasteners on both sides, with fixing bolt holes provided on the outer wing of the bottom edge of the C-type fastener for fixation to a special clamp.

[0007] Furthermore, to better realize this utility model, bolt holes are provided at the connection point between the C-type fastener and the dedicated clamp, and the side of the C-type fastener connected to the clamp is widened. This is to allow the use of the same clamp if a photovoltaic support appears in the same location, and to separate them using a loosening washer. The clamp is fastened to the first C-type fastener and the second C-type fastener using hexagonal socket head cap screws. This widened bolt hole design allows the corrosion-resistant irregular maintenance walkway and the photovoltaic support within the array to share the same clamp.

[0008] Furthermore, to better realize this utility model, the special clamp can be a standard part purchased from the market according to the roof, without additional processing. This saves on the overall construction cost of the project and does not damage the corrugated steel roof tiles, making installation simple and convenient. The clamp is selected according to the roof tile type, and the supporting partition and the anti-corrosion irregular-shaped maintenance walkway are welded together, without compromising the overall functionality of the walkway.

[0009] The beneficial effects of this utility model are: This utility model uses C-type fasteners and clamps to fix irregularly shaped maintenance walkways, breaking away from the traditional method of using brackets for fixation. This greatly saves project construction costs. During the entire installation process, the location of the maintenance walkway can be reasonably designed according to the project's maintenance needs, no longer restricted by space, thus improving overall work efficiency and saving steel consumption.

[0011] The technical solutions of the present invention will now be described in detail, clearly, and accurately with reference to the accompanying drawings of the embodiments thereof. Obviously, the described embodiments are only a part of the embodiments of the present invention and do not represent all the embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0012] Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0013] Figures 1-3 This is a specific embodiment of the present invention, which describes a fastening method for a corrosion-resistant, irregularly shaped maintenance walkway within a photovoltaic array on a corrugated steel roof. In this embodiment, the maintenance walkway is secured within the groove of a C-shaped fastener, eliminating the need for holes in the walkway. The C-shaped fastener has the advantage of a C-shaped shape, with elongated and widened upper and lower sides and internal threads, enhancing overall stability.

[0014] The bottom of the corrosion-resistant, irregularly shaped maintenance walkway is fixedly connected to a special clamp using fasteners, and the connection is secured with hexagonal bolts. No holes were drilled in the roof corrugated steel sheets or the maintenance walkway during the entire installation process, and no welding was performed during construction. This ensures the safety of the roof without affecting the overall performance. As shown in the figure, the anti-corrosion irregular maintenance walkway 1 is machine-pressed and folded with inward buckling on both sides to increase the support strength. The anti-corrosion irregular maintenance walkway 1 is equipped with a support plate 4 inside. The support plate 4 and the walkway 1 are prefabricated and welded together. This connection method can not only strengthen the support and prevent swaying when people walk on it, but also does not affect the overall aesthetics and practicality.

[0015] The corrosion-resistant, irregularly shaped maintenance walkway 1 is mainly fixed by the first C-type fastener 2 and the second C-type fastener 3. The C-type fasteners have threaded holes at the top and bottom to prevent slippage. Moreover, no holes or openings are made on the entire installation contact surface between the fasteners and the maintenance walkway. The installation method is to first install the first C-type fastener 2 on the same side, and then install the second C-type fastener 3 on the other side. After the fasteners on both sides are clamped, the next step is carried out.

[0016] In this embodiment, the first C-type fastener 2 and the second C-type fastener 3 have a widened bottom design and additional threads on the inner sides to enhance anti-slip function. They are connected and fixed to the roof-specific clamp using hexagonal bolts. The fastener is characterized by a widened bottom two-wing design, which allows it to share a clamp with the photovoltaic support within the photovoltaic array.

[0017] The special clamp 5 for fixing to the roof can be purchased as a standard part according to the type of color steel tile roof. It is easy to install and convenient to purchase, which greatly reduces the installation cost of the maintenance walkway and solves the limitations of space constraints during the installation of the maintenance walkway, as well as the problems of difficult installation and inconvenient construction.

[0018] Based on the above summary, this utility model case is only used to illustrate the technological innovation breakthrough of this utility model and is not intended to limit it. Other equivalent modifications or substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the essential invention of this utility model, are all considered to be covered within the scope of the claims of this utility model.
