Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and more specifically, to a photovoltaic bracket structure for a saddle plate roof. Background Art

[0002] Prestressed concrete saddle-shaped shell panels, also known as saddle panels, offer advantages such as waterproofing, earthquake resistance, fire resistance, ease of installation, low cost, durability, and maintenance-free operation. They are widely used in large-span buildings. Due to the unique structure of the roof panel, which is curved like a saddle, this imposes significant limitations on the design of photovoltaic mounting brackets. Traditional mounting brackets were mostly constructed with two columns, the base of which was fixed to the curved surface of the panel with expansion bolts or with a concrete counterweight placed at the bottom of the curved panel. The double-column support type means that the array spacing and module angles of the module arrangement will be limited by the saddle plate shape, resulting in a relatively small arrangement capacity and affected power generation. Due to the thinness of the saddle plate, longer expansion bolts are required for fixing in areas with high wind loads. In such cases, the conditions for expansion bolts are not met, and the bolts will damage the roof, causing potential leaks and shortening the service life of the saddle plate. Alternatively, larger and more concrete counterweights are used. When the roof design bearing capacity is insufficient, this solution will not be applicable. Moreover, due to the special structure of the saddle plate, the lifting and transportation of the concrete counterweight foundation is also a construction challenge. Therefore, it is necessary to design a support type specifically for saddle roofs to solve the above technical problems. Utility Model Content
