Bracket structure for PVC (polyvinyl chloride) roof

Abstract

The invention relates to a bracket structure for a PVC (polyvinyl chloride) roof. A rectangular bracket is combined by longitudinally and transversely arranging a plurality of bottom beams and purlines which are connected with one another; a plurality of photovoltaic components are fixed to the purlines; a plurality of fixing components are matched in the bottom beams; each fixing component is arranged on the corresponding bottom beam through a bolt. The bracket structure provided by the invention is simple in structure, flexible in assembly and disassembly and convenient to mount; the rectangular bracket formed by combining the purlines and the bottom beams can better meet the paving requirement on the photovoltaic components on the PVC roof; the problems about bearing capacity and long-term reliability is also solved under the condition that the roof is not damaged; the fixing components are also additionally arranged to prevent the rectangular bracket from displacing and reduce deformation of a fixing material; the bracket structure can be applied to the coastal regions or the regions with relatively high wind power; the wind resistance of the photovoltaic components and the long-term reliability of the fixing material are guaranteed; meanwhile, inclination parts are arranged at the bottom end of the bottom beams, so that the chance that the rectangular bracket pierces out and contacts with the roof is reduced, and the roof made of the flexible material is prevented from being damaged.

Description

technical field [0001] The invention relates to a support structure, in particular to a support structure for a PVC roof. Background technique [0002] In recent years, my country's photovoltaic industry has developed rapidly, especially distributed photovoltaics, which can realize the spontaneous use of electric energy and local consumption, which has played a better role in peak shaving and valley filling. In distributed photovoltaic projects, the type of roof directly affects the investment and income of the project. The common roof types are mainly color steel tile roofs and concrete roofs. The above two types of roofs have waterproof problems, which bring problems to rooftop photovoltaic projects. There are many uncertain factors. In order to solve the problem of waterproofing, PVC flexible materials are now used as roofing materials. This material has the advantages of long service life and good waterproof performance. However, PVC flexible materials are rarely use...

Problems solved by technology

In distributed photovoltaic projects, the type of roof directly affects the investment and income of the project. The common roof types are mainly color steel tile roofs and concrete roofs. The above two types of roofs have waterproof problems, which bring problems to rooftop photovoltaic projects. There are many uncertain factors. In order to solve the problem of waterproofing, PVC flexible materials are now used as roofing materials. This material has the advantages of long service life and good waterproof performance. However, PVC flexible materials are rarely used in photovoltaic modules in China. And there are many fixing problems of photovoltaic modules
