Description

Technical Field

[0001] This utility model relates to the field of building and new energy technology, specifically to a novel roof-mounted photovoltaic support structure. Background Technology

[0002] With the transformation of the global energy structure and the increasing awareness of environmental protection, new energy sources, especially photovoltaic power generation, have become an important direction for future energy development. As a clean, renewable, and low-carbon energy form, photovoltaic power generation can not only effectively reduce greenhouse gas emissions, but also improve energy utilization efficiency and reduce transmission losses through distributed energy methods.

[0003] In recent years, technological advancements and policy support have propelled the rapid development of the photovoltaic (PV) power generation industry, with building-roofed PV systems becoming a key application area. However, the available areas for PV construction are gradually decreasing, especially in large-span factories and warehouses on the outskirts of cities. These buildings often use lightweight materials like corrugated steel sheets for their roofs, which lack sufficient load-bearing capacity, and directly installing PV modules would damage the roof surface. Furthermore, adding PV systems increases the roof load, requiring reinforcement of the structural components, thus increasing construction complexity and cost.

[0004] Therefore, how to fully utilize the roof space of these large-span buildings without damaging the existing roof structure has become a pressing challenge for the photovoltaic industry. There is an urgent need for a new type of rooftop photovoltaic support structure that can optimize stress distribution, reduce load, and adapt to roof environments unsuitable for permanent occupancy, thereby enabling efficient and safe installation of photovoltaic systems.

[0005] This utility model was proposed against this background, aiming to provide an innovative photovoltaic support structure for large-span factories, warehouses and other buildings, solve the application problems of existing systems on complex roofs, expand the installation area of ​​new energy sources, and provide more space and possibilities for the promotion and application of photovoltaic power generation.

[0029] 3. Photovoltaic modules. Detailed Implementation

[0030] To facilitate understanding of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings illustrate a preferred embodiment of this utility model, but the utility model is not limited to these embodiments and can actually be implemented in many different forms. These embodiments are provided to help those skilled in the art to more comprehensively and deeply understand the technical content of this utility model.

[0031] This embodiment takes a building structure with a span of 30m, a height of 12m, and a longitudinal length of 40m as an example, and constructs a flexible photovoltaic support system with a height of approximately 2m on its roof. The example building structure is an express delivery warehouse structure, which is a large-span structure. The roof and part of the walls are covered with corrugated steel sheets, which have low load-bearing capacity and are not suitable for directly installing photovoltaic modules 3. Therefore, the following novel structural form and construction scheme are proposed:

[0032] like Figure 1 and Figure 2 As shown, the building structure includes steel columns 11, brick walls 12, and a color steel tile building exterior surface 13; the main structure of the roof photovoltaic support structure is a tensioned beam structure, including curved beams 21, struts 22, tension cables 23, structural connecting devices 24, metal sleeves 27, and supporting round rods 28; the photovoltaic modules 3 are installed on the supporting round rods 28 of the roof photovoltaic support structure.

[0033] like Figure 3 As shown, the strut 22 of the tensioned beam structure includes a curved beam connector 221, a vertical rod 222, and a tension cable connector 223. The structural connection device 24 connects the tension cable 23 to the curved beam 21, reducing the deflection of the curved beam under load by rationally controlling the prestress in the tension cable 23. The curved beam 21 is preferably made of lightweight materials such as wood (e.g., glued laminated timber), composite materials (e.g., fiberglass, carbon fiber), or alloy materials (e.g., aluminum alloy) to reduce the self-weight load of the roof-mounted photovoltaic support structure 2. The cross-section of the curved beam 21 can be a hollow section or a box section; when using alloy materials, an I-beam section can be used.

[0034] like Figure 4 As shown, the curved beam connector 221 includes a curved beam base plate 2211, a spherical stud 2212, and an upper sleeve 2213. The curved beam connector 221 is connected to the curved beam 21 via the curved beam base plate 2211 using self-tapping rivets. The spherical stud 2212 is prefabricated together with the curved beam base plate 2211. The upper sleeve 2213 is connected to the top of the vertical rod 222 via self-tapping rivets and also serves as a slot for the spherical stud 2212, restricting its movement while allowing it to rotate.

[0035] like Figure 5 and 6As shown, the tension cable connector 223 includes a lower sleeve 2231, an end plate 2232, a tension cable support 2233, a baffle 2234, and U-bolts 2235. The lower sleeve 2231 is used to connect to the bottom of the vertical rod 222 and is fixed by self-tapping rivets. The end plate 2232, tension cable support 2233, and baffle 2234 are integrally formed with the lower sleeve 2231. The tension cable support 2233 is used to support the tension cable 23 and transmit the reaction force to the curved beam 21. The end plate 2232 and baffle 2234 are used to restrict the tension cable 23 and prevent it from detaching from the cable connector 223. Multiple bolt holes are reserved on the end plate 2232 to install U-bolts 2235, which are used to restrict the tension cable 23 and ensure its stability.

[0036] like Figure 7 As shown, the structural connection device 24 includes an anchoring connector 241, an anchoring end plate 242, an end sleeve 243, and a rivet 244; the support 25 is made of metal and is fixed to the steel column 11 of the building structure 1 by welding, preventing other structural components of the roof from bearing the load of the additional photovoltaic support structure 2. The support 25 is connected to the curved beam 21 by a pin 26, ensuring that the end of the curved beam 21 can rotate freely in the plane.

[0037] like Figure 8 As shown, the curved beam 21 has multiple pre-drilled holes for installing the metal sleeve 27. The center of the metal sleeve 27 can be inserted into the supporting rod 28, and the redundant length of the metal sleeve 27 (slightly larger than the cross-sectional width of the curved beam 21) ensures that when the supporting rod 28 is connected to the curved beam 21, the holes will not be damaged due to excessive bending moment or supporting force. The supporting rod 28 is made of metal and has a hollow cross-section to ensure sufficient strength and low self-weight.

[0038] like Figure 9 As shown, a metal collar assembly 29 can be added during the interlocking installation of the supporting round rod 28 and the metal sleeve 27. The metal collar assembly 29 includes a short metal support column 291 and a metal collar 292. The short metal support column 291 supports the photovoltaic module 3 and is fixed to the bracket of the photovoltaic module 3 by welding. The metal collar 292 is spot-welded to the supporting round rod 28, avoiding large-area welding that weakens the strength of the supporting round rod 28. This construction scheme improves construction convenience and ensures that gaps are formed between adjacent photovoltaic modules 3 to reduce the impact of wind loads on the photovoltaic modules 3.
