Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a grid structure used in photovoltaic supports. Background Technology
[0002] In the field of photovoltaic support systems, traditional support structures have many shortcomings when applied to scenarios such as agriculture and fishponds. For example, the span of ordinary C-shaped steel is limited, making it difficult to meet the needs of large spans; welding is usually required during construction, which not only depends on the operator's skills but also increases the construction period and production costs; at the same time, the stability of traditional structures needs to be improved, making it difficult to maintain good structural performance under large spans, and the high requirements for processing precision increase the difficulty of production.
[0003] Therefore, in view of the shortcomings of existing technologies, it is necessary to design a grid structure for photovoltaic support to solve the above problems. Utility Model Content
[0004] To overcome the shortcomings of the prior art, the present invention aims to provide a grid structure for use in photovoltaic brackets, so as to solve the problems of small span, long construction period, high production cost, poor stability and high processing precision requirements of photovoltaic brackets in the prior art.
[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a grid structure applied in photovoltaic support systems, comprising:
[0006] A two-dimensional truss is composed of an upper chord, a lower chord, and multiple sets of web members. The upper chord and the lower chord are arranged in parallel with intervals, and the multiple sets of web members are connected between the upper chord and the lower chord. Two sets of two-dimensional trusses are arranged in parallel with intervals and are fixedly connected by support beams.
[0007] Purlins, multiple sets of purlins are mounted on the top side of the upper chord of the two sets of two-dimensional trusses and are set perpendicular to the two-dimensional trusses;
[0008] Diagonal bracing, multiple sets of the diagonal bracing are erected on the bottom side of the upper chord of the two sets of two-dimensional trusses, and are inclined to the two-dimensional trusses;
[0009] The coupling brace consists of multiple sets of coupling braces, one end of which is connected to the lower chord of the two-dimensional truss, and the other end of which is connected to the bottom side of the purlin, and is inclined to the two-dimensional truss and the purlin.
[0010] The preferred technical solution is that the two adjacent sets of web members, the upper chord, and the lower chord form an isosceles trapezoidal structure.
[0011] The preferred technical solution is as follows: the support beam is configured as an H-shaped structure, including one horizontal beam and two vertical beams. The two vertical beams are fixed at both ends of the horizontal beam. The two vertical beams are correspondingly arranged with two sets of two-dimensional trusses. The upper and lower ends of the vertical beams are respectively used to connect the upper chord and the lower chord.
[0012] The preferred technical solution is as follows: the upper chord and the lower chord have the same structure, both consisting of two sets of parallel C-shaped steels spaced apart, and the web members and the vertical beams are sandwiched between the two C-shaped steels.
[0013] The preferred technical solution is that two adjacent diagonal braces form a ∠-shaped structure.
[0014] A preferred technical solution is that the horizontal beam and the vertical beam, the vertical beam and the upper chord, the vertical beam and the lower chord, the upper chord and the web member, the lower chord and the web member, the purlin and the upper chord, the diagonal brace and the upper chord, the coupling brace and the lower chord, and the coupling brace and the purlin are all fixedly connected by bolts.
[0015] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:
[0016] This space frame structure can achieve large spans, with lengths and spans easily exceeding twice that of ordinary C-shaped steel designs. It is used for building photovoltaic systems in agricultural and fishery areas, requiring fewer columns and having higher support structures, thus maximizing space utilization and benefiting agricultural and fishery income while improving work efficiency.
[0017] The key feature of this space frame structure is its use of cold-formed C-shaped steel and hot-formed steel. The entire structure requires no welding; all parts are connected by bolts. This reduces the construction period, lowers production costs, and avoids the problems associated with welding, which relies on skilled workers.
[0018] This space frame structure is mainly composed of two-dimensional trusses, combined with diagonal braces, corner braces, and purlins, to achieve the stability of a three-dimensional truss (i.e., space frame).
[0019] In this space frame structure, both the upper and lower chords of the two-dimensional truss are composed of two C-shaped steel sections. This eliminates the need for precision in the steel sections themselves and their compatibility with the web members, thus reducing the requirements for machining accuracy. Furthermore, the two C-shaped steel sections are spread apart by the web members, allowing the infinite material to achieve a wider effect. The greater the truss width, the higher its strength.
