Description

Technical Field

[0001] This utility model belongs to the field of building material technology, and specifically relates to a modular power generation and heat insulation roof building material. Background Technology

[0002] The typical structure of existing rooftop photovoltaic modules usually includes three parts: photovoltaic panels, support system, and roof base. The support system is mostly composed of steel purlins, connectors, and adjusting components. The photovoltaic panels are fixed to the support by bolts or clips, and the support is connected to the roof base (such as concrete roof or metal roof) by expansion bolts.

[0003] From a structural perspective, this type of design has the following technical defects: In existing structures, the photovoltaic panels and the roof substrate are only separated by a support frame, forming a gap of 50mm to 100mm, without a dedicated insulation layer. Heat can be directly conducted through the roof substrate; for example, the thermal conductivity of metal roofs can be as high as 50W / (m·K) or more. Especially in cold regions, indoor heat easily diffuses to the outside through the roof substrate, failing to meet building energy efficiency standards. Furthermore, the back of the photovoltaic panels is in direct contact with the support frame, and airflow within the gap is obstructed by the support frame, resulting in the ineffective dissipation of heat generated by the photovoltaic panels under strong sunlight (light absorption conversion rate is approximately 15% to 20%, with the remainder converted into heat). Actual measurement data shows that the operating temperature of the photovoltaic panels under this structure can reach over 60℃, and for every 1℃ increase in temperature, its power generation efficiency decreases by approximately 0.4%, severely impacting power generation performance. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a modular power-generating and heat-insulating roofing building material.

[0005] The technical solution of this utility model is: a modular power-generating and heat-insulating roofing building panel, comprising an indoor panel, an outdoor panel, an insulation layer, and a power-generating glass panel. The indoor panel has a rectangular structure with flanges on both sides in the horizontal direction; the outdoor panel is set on the flanges, forming an installation gap with the indoor panel; the outdoor panel has multiple sets of ribs evenly distributed along the horizontal direction, all of which are located on the side of the outdoor panel away from the indoor panel; the insulation layer is set within the installation gap; the power-generating glass panel is fixed on the ribs, and an air circulation interlayer is formed between the power-generating glass panel and the outdoor panel.

[0006] Furthermore, the outdoor panel has mortise and tenon structures on its two lateral sides, which are used to connect two adjacent building panels laterally.

[0007] Furthermore, the mortise and tenon structure includes: a tenon, located on either side of the lateral side of the outdoor panel; and a mortise, structurally matching the tenon, located on the other side of the lateral side of the outdoor panel. Two laterally adjacent building panels are joined together by the tenon and the mortise.

[0008] Furthermore, the longitudinal section of the tenon and the mortise fitting part is an isosceles trapezoid.

[0009] Furthermore, the longitudinal length of the outdoor panel is 80mm to 100mm longer than that of the indoor panel and the insulation layer; one longitudinal edge of the outdoor panel is flush with one longitudinal edge of the indoor panel, and the other longitudinal edge of the outdoor panel is flush with one longitudinal edge of the insulation layer. The outdoor panels of two adjacent building panels overlap each other.

[0010] Furthermore, there is an overlap joint between two longitudinally adjacent building panels, and the overlap joint is filled with a sealing strip.

[0011] Furthermore, the two lateral sides of the power-generating glass panel are aligned with the two lateral sides of the outdoor panel, and a first adhesive strip is filled between the lateral sides of the power-generating glass panel and the corresponding lateral sides of the outdoor panel.

[0012] Furthermore, a second adhesive strip is filled between the longitudinal side of the power-generating glass panel and the longitudinal side of the outdoor panel.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention incorporates an air circulation interlayer between the power-generating glass panel and the outdoor panel, forming airflow channels within this interlayer. These airflow channels are interconnected between adjacent building panels. During use, the naturally flowing air within these channels carries away heat from the surface of the power-generating glass panel, thereby reducing its operating temperature and improving power generation efficiency. Furthermore, this invention includes a heat insulation layer between the indoor and outdoor panels, effectively cutting off heat conduction paths and preventing heat loss from the interior due to heat conduction, thus enhancing the thermal insulation performance of the building panels.

[0017] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] Example like Figure 1 , Figure 2 , Figure 3The modular power-generating and heat-insulating roofing material shown includes an indoor panel 1, an outdoor panel 2, an insulation layer 3, and a power-generating glass panel 4. The indoor panel 1 has a rectangular structure with flanges 10 on both sides in the horizontal direction. The outdoor panel 2 is mounted on the flanges 10, forming an installation gap with the indoor panel 1. The outdoor panel 2 has multiple sets of ribs 20 evenly distributed along the horizontal direction, all of which are located on the side of the outdoor panel 2 away from the indoor panel 1. The insulation layer 3 is disposed within the installation gap. The power-generating glass panel 4 is fixed on the ribs 20, and an air circulation interlayer 5 is formed between the power-generating glass panel 4 and the outdoor panel 2.

[0019] It should be noted that: in this embodiment, both the indoor panel 1 and the outdoor panel 2 are made of 0.5mm thick bent metal steel plates, the insulation layer 3 is made of 20mm thick aerogel felt with a thermal conductivity ≤0.015W / (m・K), and the electro-glass panel 4 is made of 7mm thick cadmium telluride photovoltaic glass. The electro-glass panel 4 is bonded to the ribs 20 with silicone structural adhesive.

[0020] Preferably, the outdoor panel 2 is provided with tenon and mortise structures 21 on both sides in the lateral direction. The tenon and mortise structures 21 are used to connect two adjacent building panels in the lateral direction.

[0021] Preferred, such as Figure 4 , Figure 5 As shown, the mortise and tenon structure 21 includes a tenon 211 and a mortise 212. The tenon 211 is located on either side of the exterior panel 2 in the lateral direction. The mortise 212 is structurally matched with the tenon 211 and is located on the other side of the exterior panel 2 in the lateral direction. Two adjacent building panels in the lateral direction are joined together by the tenon 211 and the mortise 212.

[0022] Preferably, the longitudinal section of the mating part of the tenon 211 and the mortise 212 is an isosceles trapezoid.

[0023] Preferred, such as Figures 6 to 9 As shown, the longitudinal length of the outdoor panel 2 is 80mm~100mm longer than that of the indoor panel 1 and the insulation layer 3. One longitudinal edge of the outdoor panel 2 is flush with one longitudinal edge of the indoor panel 1, and the other longitudinal edge of the outdoor panel 2 is flush with one longitudinal edge of the insulation layer 3. The outdoor panels 2 overlap between two adjacent building panels in the longitudinal direction.

[0024] Preferably, there is an overlap joint between two longitudinally adjacent building panels, and the overlap joint is filled with a sealing strip.

The insulation layer 3 is a 20mm thick aerogel felt; therefore, in actual use, for irregular areas, a filling layer 6 is provided, and the filling layer 6 is made of polyurethane foam.

[0028] The assembly method in this embodiment is as follows: The main building structure is pre-installed with steel keel, and the spacing of the keel matches the size of the panels.

That is, the tenon 211 of the second building panel is laid on the tenon 212 of the first building panel and nailed to fix it. After the installation of the first row of panels is completed, butyl waterproof tape is pasted at the joint between the second row of panels and the first row of panels. Then the second row of panels is installed. The outdoor panels 2 of the second row of panels overlap with the first row of panels by 90mm and are fixed with screws at the joint to make the joint between the two rows of panels tightly connected.

[0030] EPDM sealant strips are filled between the power-generating glass panels 4 of the two rows of building materials for waterproofing and sealing.
