Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic metal enclosures (BIPV), and in particular to an assembled treadable BIPV roof. Background Art

[0002] In response to the national call for energy conservation, emission reduction, low-carbon environmental protection, and the successful achievement of the "dual carbon goals," distributed rooftop photovoltaics (PV) are gaining increasing attention. They can fully utilize existing rooftop resources to install PV systems, thereby reducing the use of thermal power. Building-integrated photovoltaics (BIPV) is the mainstream development approach for distributed PV installations, as BIPV integrates PV power generation into building functions, creating a cohesive whole and ensuring green and energy-efficient buildings. However, currently, crystalline silicon PV modules dominate the market, accounting for over 95% of the market share. Crystalline silicon modules are divided into framed and frameless modules. Framed modules are typically connected to metal roofs using clamps and rails. The frame thickness of framed modules is typically much thicker than that of photovoltaic glass, and the modules are suspended in the air, making them impassable. Therefore, rooftop installations typically require a dedicated maintenance access to facilitate subsequent maintenance. However, this access takes up space for PV modules, reducing installed capacity by over 20% and increasing the cost of access.

[0003] The frameless modules use double-glass modules. Due to the frameless support, their own load-bearing capacity needs to be supported by the panels that match the modules to ensure that people can walk on and step on them. When the roof panel type does not match the photovoltaic modules, the installation of the photovoltaic system cannot be completed, which greatly limits the installation of the photovoltaic system.

[0004] At the same time, whether it is a framed photovoltaic module or a frameless photovoltaic module, the installation method is mainly on-site installation, that is, the photovoltaic modules are transported to the site and the installation of the photovoltaic modules is completed at the project site. This not only takes a long installation period, but also causes damage to the photovoltaic modules during the installation process. Utility Model Content

[0005] In response to the above-mentioned problems existing in the existing technology, the utility model provides an assembled trampled BIPV roof that can be walked on by people without reserving operation and maintenance channels. The installed capacity can be increased by more than 20%, and the operation and maintenance personnel in the later stage can walk directly on the upper part. At the same time, because it adopts a frameless design, it can achieve a dust-free effect, and the surface can be cleaned by flushing with clean water or using a cleaning robot.

[0006] The utility model adopts the following technical solutions:

[0007] An assembled, steppable BIPV roof comprises a photovoltaic module and a plurality of bottom support frames mounted on a metal roof panel. The plurality of bottom support frames are arranged in parallel and at intervals on the metal roof panel. The photovoltaic module is a double-glass frameless module, which is fixedly connected to the bottom support frames by structural adhesive to form a BIPV assembly unit.

[0008] Preferably, a plurality of the BIPV assembly units are formed on the metal roof panel, and the bottom support frames of two adjacent BIPV assembly units are assembled by overlapping or butting.

[0009] Furthermore, a decorative cover plate is installed at the joint of the two bottom support frames.

[0010] Preferably, the decorative cover plate is provided with a plurality of oblong holes.

[0011] Preferably, the double-glass frameless assembly includes a double layer of tempered glass with a thickness of more than 2 mm and a battery cell, and the battery cell is composited between the double layer of tempered glass.

[0012] Preferably, the metal roof panel is one of a 360° standing seam panel type, a 270° round-mouth bite panel type, a 180° standing seam panel type, and an exposed nail panel type.

[0013] Preferably, each of the BIPV assembly units is provided with 3-4 bottom support frames arranged in parallel and at intervals.

[0014] The technical solution of this utility model has the following advantages:

[0015] A. The assembled trampled BIPV roof provided by the present invention combines the frameless double-glass photovoltaic modules and the bottom support frame into a whole through the structural adhesive bonding process in the factory. The bottom support frame can well support the frameless double-glass modules on the upper part. Compared with the traditional framed modules, the cost of the aluminum alloy frame can be saved. At the same time, the aluminum alloy frame modules cannot be stepped on. The present invention can be stepped on by people and does not require reserved operation and maintenance channels. While saving the cost of operation and maintenance channels, the installed capacity can be increased by more than 20%. Later operation and maintenance personnel can walk directly on the upper part. At the same time, because it adopts a frameless design, it can achieve a dust-free effect. The surface can be cleaned by flushing with clean water or using a cleaning robot.

[0016] B. This utility model adopts the principle of assembly design. It can be installed by simply connecting with screws after being transported to the project site, which greatly improves the installation efficiency.

[0017] C. Traditional frameless adhesive process components require on-site gluing, which is slow and takes 1 to 2 weeks from the completion of gluing to the generation of adhesive strength. During this period, the photovoltaic components are at risk of slipping or being blown away by the wind. The utility model combines the bottom support frame and photovoltaic components in the factory, ensuring product quality. On-site construction only requires the effective connection of the bottom support frame and the clamp, greatly improving installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0037] like Figure 1-4As shown, the utility model provides an assembled treadable BIPV roof, including a photovoltaic module 1 and a plurality of bottom support frames 3 installed on a metal roof panel 2. The plurality of bottom support frames 3 are arranged in parallel and at intervals on the metal roof panel 2. The photovoltaic module 1 is preferably a double-glass frameless module, which is fixedly connected to the bottom support frame 3 by a structural adhesive 4 to form a BIPV assembly unit a. 3 to 4 bottom support frames 3 can be set at the bottom of the photovoltaic module 1 as needed. The structural adhesive 4 here is a special structural adhesive. The special structural adhesive 4 is evenly spaced (can also be full-length) on the upper surface of the bottom support frame 3, and then the double-glass frameless module is bonded to the bottom support frame 3 by the special structural adhesive 4. The double-glass frameless module is preferably composed of a double layer of tempered glass with a thickness of more than 2 mm and a battery cell in the middle. The double-glass frameless module has good impact resistance and can withstand an impact force of 5400pa. As shown in the attached Figure 4 As shown, the utility model can be stepped on by people, and the front bearing capacity can reach 8100pa. Figure 5 and Figure 6 As shown, a plurality of BIPV assembly units a are formed on the metal roof panel 2, and the bottom support frames 3 of two adjacent BIPV assembly units a are assembled by overlapping or butting. Figure 5 The figure shows the paving effect of multiple BIPV assembly units of the utility model, which are connected to the metal roof panel 2 through the clamp 6. Due to its unique connection method, the metal roof panel 2 can adopt a variety of plate types, such as 360° upright lock seam plate type, 270° round mouth bite plate type, 180° upright lock seam plate type, exposed nail plate type, etc., all of which can achieve effective connection.

[0038] As attached Figure 7 and attached Figure 8 As shown, two BIPV assembly units a are assembled by overlapping or docking the bottom support frame 3. After the assembling, the photovoltaic modules 1 and the photovoltaic modules 1 are connected in series, which will cause the wiring bellows 8 to be exposed on the outside of the photovoltaic modules 1. As a preferred embodiment of the present invention, a decorative cover plate 5 can be added to the splicing of the photovoltaic modules 1, which not only plays an aesthetic role, but also plays a role in protecting the cables of the photovoltaic modules 1. Figure 9 As shown, a plurality of oblong holes 51 are provided on the upper portion of the decorative cover plate 5, which can guide the water accumulated on the upper portion of the photovoltaic module 1 to the metal roof panel 2 through the oblong holes 51 during rainy days. Figure 10 and Figure 11 shown.

[0039] The utility model can be applied not only to roofs but also to walls, such as Figure 10 As shown, when the outer wall panel is a corrugated metal sheet, self-tapping screws can be used to directly penetrate the bottom support frame 3 and connect to the back wall purlin 9.

[0040] Figure 12 and Figure 13 The figure shows an assembled prefabricated trampled BIPV roof. In the factory, the frameless double-glass components and the bottom support frame are combined into a whole through a gluing process. The bottom support frame can well support the frameless double-glass components on the upper part, which can be stepped on by people. There is no need to reserve an operation and maintenance channel. The installed capacity can be increased by more than 20%, and the operation and maintenance personnel can walk directly on the upper part. At the same time, because it adopts a frameless design, it can achieve a dust-free effect. The surface can be cleaned by flushing with clean water or using a cleaning robot. Since the utility model adopts the principle of prefabricated design, it can be transported to the project site and installed by simply connecting with screws, which greatly improves the installation efficiency.

[0041] Any matters not described in the present invention are applicable to the prior art.

[0042] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
