Description

Technical Field

[0001] The utility model relates to a rigid structure roof panel system, in particular to a BIPV rigid structure roof panel system with high adaptability. Background Art

[0002] The roof panels of mainstream products of photovoltaic building integrated BIPV (Building Integrated PV, PV stands for Photovoltaic) include water guide grooves and corrugated steel plates. The fixing methods are mainly divided into bracket fixing and adhesive fixing. The structural load-bearing conditions are divided into two categories: passenger-carrying and non-passenger-carrying.

[0003] Currently, BIPV products include the following:

[0004] 1. "Rui Ding" and "Shuang Ding" products are fixed by clamps to facilitate construction and maintenance; U-shaped and W-shaped water guides are set under the photovoltaic modules to effectively guide rainwater on the roof; and a raised seat is set to directly raise the roof without affecting the normal production of the enterprise, avoiding the removal of roof tiles, and is suitable for various color steel tile roofs, but the bearing capacity is weak.

[0005] 2. "Fuding" BIPV roof panel products use double-peak corrugated steel plates, which can be flexibly fixed by clamps or adhesives; the product uses a combination of 360° vertical locking and concealed buckles to improve waterproof performance; it is suitable for photovoltaic modules of common sizes on the market, and can be customized with a variety of materials, such as color-coated steel plates, aluminum-zinc-coated panels, and zinc-aluminum-magnesium-coated panels. Due to the width of the steel coil, the current version can no longer meet the requirements of larger photovoltaic modules; photovoltaic and maintenance loads mainly act on the locking edge, which is the point where the clamp is used and is prone to deformation and leakage; at the same time, the roof panel waveform is relatively short, which is not conducive to the strength and force of the roof panel.

[0006] 3. The "Longding" product uses double-glass packaging to balance the load-bearing capacity, can carry people, eliminates the need for maintenance channels, and increases the laying area; it uses corrugated steel plates and uses structural adhesive for fixing, and needs to use Longi's automated installation equipment for gluing. The construction is simple but not conducive to maintenance and removal; in addition, the product has special size requirements, and the photovoltaic components are only suitable for Longi's 2272*1128 double-glass frameless components. Because the photovoltaic panel is positioned by gluing, the construction process is high and there is a long-term risk of aging and falling off; there are directional requirements for photovoltaic components, and the mainstream components in the market cannot be used, which is not conducive to cost control. Summary of the invention

[0007] The purpose of the utility model is to design a highly adaptable BIPV rigid structure roof panel system, which can meet the continuous high-efficiency and large-scale development needs of crystalline silicon photovoltaic modules, meet the adaptation requirements of modules of various sizes and types, including the current mainstream 450W, 560W and other module sizes in the market, and adapt to larger modules of 700W and above in the future; at the same time, it improves the product life, waterproof performance and structural bearing capacity, and ensures the quality stability within the 25-year operation and maintenance cycle of photovoltaics.

[0012] A plurality of fixing brackets, each fixing bracket is an inverted U-shaped plate structure, the open end of the lower end of which is bent and extended to both sides to form a fixing portion, and is connected to the purlin or roof beam by bolts or screws; the top surface of the fixing bracket protrudes upward to form a buckle portion that can be inserted into the locking portion accommodating cavity of the roof panel;

[0013] A plurality of photovoltaic clamp assemblies are respectively arranged on the fixing brackets, and the photovoltaic clamp assemblies include:

[0014] A fixing block, the top surface of which is provided with a fixing plate, and a connecting hole is provided in the center of the fixing plate; the fixing block abuts against the top surface of the buckle portion of the fixing bracket;

[0015] The first clamping member is a plate structure, the upper part of which is arranged on one side of the fixing block, and the lower part of the first clamping member is bent inwardly and extended to form a hook part, and is hooked on the bottom side of the outer protrusion of the roof panel locking part;

[0016] The second clamping member is a plate structure, the upper part of which is arranged on the other side of the fixing block, and the lower part of the second clamping member is bent inwardly and extended to form a hook part, and is hooked on the other side of the bottom of the convex outer part of the roof panel locking part;

[0017] The top clamping member is a plate structure in a U shape, with the open ends of the upper end bent outward and extended to form a clamping portion, which cooperates with the fixing plate to clamp and fix the photovoltaic panel; the bottom center of the top clamping member is connected to the fixing block and the fixing plate by bolts.

[0018] Furthermore, a cavity structure is provided between the bottom surface of the fixing plate and the top surface of the fixing block, and a nut cooperating with the bolt is provided in the cavity structure.

[0035] The utility model does not use too many guide rails, thus avoiding excessively high costs.

[0036] Taking into account the development trend of photovoltaic components, the utility model designs the corrugated steel plate into two types of splicing to facilitate adapting to the size of the photovoltaic panel.

[0037] The utility model designs a mature and reliable waterproof bite structure to ensure the waterproof performance in multiple environments for a long period of time.

[0038] The utility model designs a special fastener structure for the clamping piece, avoids the use of adhesive connection, solves the influence of the installation process on the life and strength, and reduces the difficulty of later maintenance and replacement of components.
