[0002] In the integrated development of green buildings and photovoltaics, leak-proof photovoltaic roofs can simultaneously achieve photovoltaic power generation, roof rain protection, and lighting functions. They can not only efficiently utilize building space to convert clean energy, but also protect the building's internal environment through reliable waterproofing. This is of great significance for improving the overall performance of buildings and promoting the popularization of low-carbon buildings.

[0003] In existing technologies, photovoltaic roofs are typically waterproofed by sealing gaps between photovoltaic panels with adhesive or sealing strips, while also incorporating a water drainage system underneath and using tiles, fixing plates, and other components to secure the roof panels. However, existing photovoltaic roofs are prone to minor leaks due to issues such as splicing gaps, installation errors, thermal expansion and contraction, and long-term deformation. More serious leaks can occur when a photovoltaic glass panel breaks, affecting the usability of the building's interior.

[0004] However, although finished photovoltaic roofs have a certain rainproof capability, due to structural limitations, they cannot be completely rainproof and a small amount of water may seep into the interior, causing trouble for the use and maintenance of the building. They are not suitable for scenarios with high requirements for waterproof precision. Therefore, a leak-proof tensile membrane photovoltaic roof is proposed to solve the above problems.

The channel steel 4 is fixedly connected to the inner side of the concrete main beams 3 by the expansion bolts 5. A lug plate 6 is provided on the channel steel 4, and the lug plate 6 is fixedly connected to the inner wall of the channel steel 4. A circular hole is opened on the lug plate 6, and a first round steel 7 is fixedly connected to the inner wall of the circular hole for fixing the first round steel 7. A concrete secondary beam 14 is fixedly connected to the side of the concrete main beam 3. A tension membrane 8 is set directly below the concrete secondary beam 14 for waterproofing. The tension membrane 8 is provided in two layers, and the end faces of the two layers of tension membrane 8 are sealed. The double-layer and sealed treatment can improve the airtightness and heat preservation effect of the tension membrane 8. A second round steel 9 is fixedly connected to both ends of the tension membrane 8. Nylon ropes 10 are installed on steel 9, and the second round steel 9 is fixedly connected to the first round steel 7 via nylon ropes 10, thus fixing the tension membrane 8 to the channel steel 4. An installation frame 16 is installed above the concrete secondary beam 14 for installing photovoltaic panels 20. Angle brackets 15 are fixedly connected to the top of the concrete secondary beam 14. There are several angle brackets 15 on the concrete secondary beam 14, which are evenly distributed on the concrete secondary beam 14 to improve the installation stability of the installation frame 16. Steel purlins 17 are fixedly connected to the bottom of the installation frame 16, and bolts 18 are installed on the angle brackets 15. Bolt 18 passes through angle bracket 15 and steel purlin 17 and is threaded with nut 19, used to fix mounting frame 16 to the top of concrete secondary beam 14. Photovoltaic panel 20 is fixedly installed on the top of mounting frame 16. Decorative panel 21 is fixedly connected to the outer wall of mounting frame 16, and the decorative panel 21 is located around the outer wall of photovoltaic panel 20 to improve the overall aesthetics of the roof. Pendant lights 25 are fixedly installed at the bottom of concrete secondary beam 14. There are several pendant lights 25, which are evenly distributed directly below concrete secondary beam 14 to provide lighting in dim environments.

[0027] Reference Figure 2 - Figure 4A ditch 11 is fixedly connected to the inner side of the left concrete main beam 3 to collect rainwater. A first sealing membrane 12 is fixedly connected to the bottom left side of the tension membrane 8, and the first sealing membrane 12 is fixedly connected to the right side of the inner wall of the ditch 11 to prevent rainwater from leaking to the bottom of the tension membrane 8. A water pipe 13 is connected to the bottom of the ditch 11 to drain the rainwater in the ditch 11.

[0028] Working principle: The bottom is anchored to the ground by the floor slab 1, and the top of the slab 2 supports the roof. The two sets of concrete main beams 3 at the top of the columns 2 serve as the core load-bearing frame, supporting both sides of the roof and providing a stable base for the installation of subsequent components. The inner side of the concrete main beams 3 is fixed with channel steel 4 by expansion bolts 5. The channel steel 4 is then tensioned and fixed with ear plates 6 to the tension membrane 8. The tension membrane 8 is located directly below the concrete secondary beams 14, forming a continuous waterproof layer that can intercept rainwater or dew. Rainwater or dew will slide down the slope of the tension membrane 8 to the left and fall into the ditch 11, and then be discharged through the water pipe 13, preventing leakage into the space below. At the same time, the membrane material itself has special properties. To further enhance the seepage prevention effect, the top of the concrete secondary beam 14 on the side of the main concrete beam 3 is fixed with an angle bracket 15, which is fastened to the steel purlin 17 at the bottom of the mounting frame 16 by bolts 18 and fixing nuts 19, so that the mounting frame 16 can stably support the photovoltaic panel 20. The tilt angle of the photovoltaic panel 20 is set at 17° to maximize the reception of sunlight and improve the power generation efficiency. At the same time, the pendant light 25 at the bottom of the steel purlin 17 can provide lighting at night. The decorative panel 21 on the outer wall of the mounting frame 16 takes into account both protection and aesthetics. The end face sealing of the two layers of tensile membrane 8 is set with double layer and sealing treatment to form a sealed cavity, which improves the airtightness and heat preservation effect of the tensile membrane 8.
