Description

Technical Field

[0001] This utility model relates to a fixing device for installing photovoltaic panels on buildings, and more particularly to an ultra-low energy consumption building photovoltaic integrated anchoring structure. Background Technology

[0002] Building Integrated Photovoltaics (BIPV) is an innovative building design concept that deeply integrates photovoltaic (PV) power generation technology with architectural design, aiming to achieve ultra-low energy consumption and energy self-sufficiency in buildings. Ultra-low energy buildings minimize energy consumption through efficient insulation, natural ventilation, and natural lighting. BIPV integrates PV modules as part of the building, such as the roof and exterior walls, achieving integrated PV power generation and building design. It utilizes the photoelectric effect of PV modules to convert sunlight into electricity. Through an intelligent control system, the generated electricity is prioritized for use within the building, with excess electricity stored or sold to the grid.

[0003] Advantages of ultra-low energy building-integrated photovoltaics (BIPV): Reduced reliance on traditional energy sources and lower carbon emissions; clean energy provided to buildings through the power generation function of photovoltaic modules; reduced building electricity costs, resulting in significant economic benefits in the long run; photovoltaic modules can be integrated into the building, such as roof tiles and exterior wall decorations, achieving a unity of aesthetics and function; customized design based on architectural style and needs, enhancing the overall aesthetics of the building.

[0004] Ultra-low energy consumption building photovoltaic integration applications: Commercial buildings, such as office buildings and shopping malls, have large roof and wall areas, which are suitable for installing photovoltaic modules; residential buildings, such as villas and apartments, can achieve photovoltaic integration through roof photovoltaics, exterior wall photovoltaics, etc.; public facilities, such as schools, hospitals, libraries, etc.

[0005] Market demand for ultra-low energy building-integrated photovoltaics (BIPV): With increasing environmental awareness and energy structure transformation, the market demand for BIPV will continue to grow. Commercial real estate and public facilities will become the main application areas for BIPV.

[0006] Building-integrated photovoltaics (BIPV) with ultra-low energy consumption is one of the important directions for future building development. Driven by technological innovation, policy support, and market demand, the BIPV industry will usher in a broader prospect for development.

[0007] Combining ultra-low energy buildings with photovoltaics requires the installation of anchoring devices on the structural components of the ultra-low energy building. Ultra-low energy buildings are divided into renovation projects and new construction projects. New construction projects are further divided into two categories: ultra-low energy composite panels constructed using traditional techniques and ultra-low energy prefabricated new construction projects. If photovoltaics are installed in a renovation project, anchors need to be installed on the existing roof or external structural walls, and the photovoltaic structure is then installed on these anchors. This is the best choice from both a safety and aesthetic perspective. For new construction or prefabricated projects, anchors need to be pre-embedded during the fabrication of the roof panels and external structural walls, ensuring a tight fit between the pre-embedded parts and the new roof or wall structure. After the entire building project is completed, the photovoltaic panels can be directly installed on the fixing devices. Therefore, an anchoring device needs to be designed to facilitate the fixation of photovoltaic panels to ultra-low energy buildings. Summary of the Invention

[0008] The purpose of this utility model is to provide an integrated photovoltaic anchoring structure for ultra-low energy consumption buildings, which solves the problem of anchoring photovoltaic panels to ultra-low energy consumption buildings and facilitates the reliable installation of photovoltaic panels on ultra-low energy consumption building structures.

[0009] The purpose of this utility model is achieved in the following way: an ultra-low energy consumption building photovoltaic integrated anchoring structure, including a threaded cylinder anchor for connecting with the building structure, the threaded cylinder anchor having a threaded inner hole at the rear, and a photovoltaic panel support hook with a bolt hole, the shank of the connecting bolt passing through the bolt hole of the photovoltaic panel support hook and the threaded inner hole of the threaded cylinder anchor being threadedly connected to fix the photovoltaic panel support hook and the threaded cylinder anchor together; and a photovoltaic panel connecting fastener for fixing to the back of the photovoltaic panel frame, the photovoltaic panel connecting fastener being fastened together with the photovoltaic panel support hook to achieve the fixation of the photovoltaic panel to the building structure.

[0010] Threaded cylinder anchors are divided into two categories: post-installed and pre-embedded.

[0011] Rear-mounted threaded cylinder anchor: There is a long strip-shaped anchor body, and the rear part of the anchor body is anchored with a threaded cylinder. The outer opening of the threaded cylinder is flush with the rear end face of the anchor body.

[0012] Pre-embedded threaded cylinder anchor: There is a long strip-shaped anchor body, and the rear part of the anchor body is anchored with a threaded cylinder. The outer opening of the threaded cylinder is flush with the rear end face of the anchor body; the front end of the anchor body is vertically fixed with a tail stop.

[0013] The tailgate is a straight or cross-shaped strip, or a disc-shaped body.

[0014] The outer circumference of the threaded cylinder is provided with several threaded cylinder anchoring protrusions, which are embedded in the anchor body to make the threaded cylinder and the anchor body firmly connected.

[0015] The circumferential profile of the anchor body is rectangular, polygonal, or circular.

[0016] The anchor body is made of a material with extremely low thermal conductivity, with the aim of breaking the thermal bridge between the photovoltaic structure and the wall.

[0017] The photovoltaic panel support hook is a strip with a rectangular cross-section and a groove along its length on the side, forming a U-shape in its cross-section; the photovoltaic panel connecting fastener is a strip with a T-shaped cross-section, and the folded edge at the front end of the photovoltaic panel connecting fastener is adapted to the groove of the photovoltaic panel support hook and can be hooked together with it.

[0018] The rear end face of the threaded cylinder anchor is flush with the outer surface of the building structure.

[0019] Common building structures used for installing photovoltaic panels include sloping surfaces, vertical walls, and flat roofs. Sloping surfaces and flat roofs are often roof surfaces, while vertical walls refer to exterior wall surfaces. Furthermore, ultra-low energy consumption composite panels are attached to the outside of the building structure, or in sequence, an inner layer of silicate material, a thermal insulation layer, and an outer layer of silicate material are attached.

[0020] Post-installed anchor installation process: Drill holes in the roof or exterior wall structure of the upgraded ultra-low energy building, clean up any debris left from drilling, add anchoring agent, insert the post-installed threaded cylinder anchor into the hole, ensuring the outer side of the threaded cylinder anchor is flush with the wall or roof surface, clean and smooth the anchoring agent around the threaded cylinder anchor to ensure a perfect bond between the threaded cylinder anchor and the structure, and install the photovoltaic structure after the anchoring agent has reached its curing time.

[0021] Pre-embedded anchor installation process: During the production and processing of the roof or exterior wall structure of a newly built ultra-low energy consumption composite panel or ultra-low energy consumption prefabricated building, threaded cylinder anchors are pre-embedded inside, allowing the anchors to be tightly integrated with the structure. After the ultra-low energy consumption building structure is completed, the photovoltaic structure can be installed.

[0022] The beneficial effects of this utility model are: the photovoltaic anchoring device designed for ultra-low energy consumption buildings facilitates the fixed installation of photovoltaic panels, making the installation convenient, firm, and neat, and allowing for quick disassembly and replacement of photovoltaic panels, thus facilitating the realization of photovoltaic integration in ultra-low energy consumption buildings.

Detailed Implementation

[0031] Reference Figures 1-7 An ultra-low energy consumption building-integrated photovoltaic (BIPV) anchoring structure includes a threaded cylinder anchor 1 for connection with a building structure 6. The threaded cylinder anchor 1 has a long, strip-shaped anchor body 11 made of a material with low thermal conductivity. A threaded cylinder 12 is anchored at the rear of the anchor body 11, with the outer opening of the threaded cylinder 12 flush with the rear end face of the anchor body 11, serving as a rear-mounted threaded cylinder anchor. Additionally, a tail stop 14 is vertically fixed at the front end of the anchor body 11. The tail stop 14 is a straight, cross-shaped strip, or a disc-shaped body, serving as a pre-embedded threaded cylinder anchor 1. The circumferential profile of the anchor body 11 is rectangular, polygonal, or circular. Several threaded cylinder anchoring protrusions 13 are provided on the outer periphery of the threaded cylinder 12. The threaded cylinder anchor protrusion 13 is embedded in the anchor body 11 to increase the connection strength, and the threaded cylinder 12 is provided with a threaded inner hole; there is also a photovoltaic panel support hook 3 with a bolt hole, and the shank of the connecting bolt 2 passes through the bolt hole of the photovoltaic panel support hook 3 and the threaded inner hole of the threaded cylinder 12 to fix the photovoltaic panel support hook 3 and the threaded cylinder anchor 1 together through threaded connection; there is also a photovoltaic panel connecting fastener 4 for fixing to the back of the photovoltaic panel 5 frame, and the photovoltaic panel connecting fastener 4 and the photovoltaic panel support hook 3 are fastened together to realize the fixation of the photovoltaic panel 5 and the building structure 6. The rear end face of the threaded cylinder anchor 1 is flush with the outer surface of the building structure 6, and the outer surface of the building structure 6 is the outer surface of the ultra-low energy consumption composite board 7 or the outer surface of the silicate material outer layer 10.

[0032] The photovoltaic panel support hook 3 is a strip with a rectangular cross-section and a groove along its length on its side, forming a U-shape in its cross-section. The photovoltaic panel connecting fastener 4 is a strip with a T-shaped cross-section. The folded edge at the front end of the photovoltaic panel connecting fastener 4 is adapted to the groove of the photovoltaic panel support hook 3 and can be hooked together with it. In addition, a fixing screw 41 can be provided. The shank of the fixing screw 41 passes through the groove or through hole on the photovoltaic panel connecting fastener 4 and connects with the threaded hole on the photovoltaic panel support hook 3. This can prevent the photovoltaic panel connecting fastener 4 from detaching from the photovoltaic panel support hook 3. It can be mainly used when the photovoltaic panel is placed horizontally.

[0033] The building structure 6 used to install photovoltaic panels 5 is divided into sloping walls, vertical walls, and flat roofs; the external insulation is of two types, one of which is to cover the outside of the building structure 6 with ultra-low energy consumption composite panels 7, see Figure 1 , Figure 2 , Figure 5 The second type is the traditional form in which the building structure 6 is sequentially covered with an inner layer of silicate material 8, a layer of thermal insulation material 9, and an outer layer of silicate material 10, as shown in the figure. Figure 6 , Figure 7 The installation of photovoltaics in ultra-low energy buildings is divided into two parts: renovation projects and new construction projects. Renovation projects use post-installed threaded cylinder anchors (1), while new construction projects use pre-embedded threaded cylinder anchors (1). See the following for the installation structure of post-installed photovoltaics on ultra-low energy composite panel sloping roofs.
