Novel support structure for PVC roof

Abstract

The invention relates to a support structure for a PVC roof. A rectangular support is formed by longitudinally and transversely arranging a plurality of bottom beams and a plurality of purlines connected with the bottom beams, and the rectangular support is installed on the roof; a plurality of photovoltaic modules are connected with the purlines, each bottom beam is further connected with a plurality of fixing parts, a fixing strip is further installed between each fixing part and the corresponding bottom beam, and each fixing strip is connected with the roof. The support structure is simple, flexible to disassemble and assemble and convenient to install, the rectangular support formed by combining the purlines and the bottom beams can well meet laying requirements of the photovoltaic modules of the PVC roof, and bearing and long-term reliability are achieved under the circumstance that the roof is not destroyed. The fixing parts are further added, so that displacement of the rectangular support is prevented, and deformation of fixing materials is reduced; thus, the support structure can also be applied to coastal areas and other areas where wind power is high, and wind resistance of the photovoltaic modules and long-term stability of the fixing materials are guaranteed.

Description

technical field [0001] The invention relates to a bracket structure, in particular to a novel bracket structure for PVC roofs. Background technique [0002] In recent years, my country's photovoltaic industry has developed rapidly, especially distributed photovoltaics, which can realize the spontaneous self-use of electric energy and local consumption, which plays a good role in reducing peaks and filling valleys. In distributed photovoltaic projects, the type of roof directly affects the investment and income of the project. The common types of roofs are mainly color steel tile roofs and concrete roofs. The above two types of roofs have waterproof problems. There are many uncertain factors. In order to solve the waterproof problem, PVC flexible materials are now used as roof 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 ma...

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
