Description

Technical Field

[0001] The utility model relates to the technical field of construction, and in particular to a fixing device for photovoltaic power generation panels on steel structure roofs. Background Art

[0002] Steel structure industrial plants are able to create large spans, and the high strength and rigidity of steel materials can withstand huge weight and pressure. Compared with traditional concrete structures, steel structures are fast to construct and have a short construction period, thereby reducing construction costs and labor costs and improving economic benefits. Therefore, they are widely used in industrial production. At the same time, solar photovoltaic power generation does not produce greenhouse gases and other pollutants. It is a renewable energy source that consumes almost no resources, so it is often installed on the roofs of steel structure industrial plants.

[0003] In order to ensure that the roof of the steel structure industrial plant is not eroded by water, the steel structure roof needs to be waterproofed. At present, the waterproofing of the steel structure roof is mainly covered with rigid aluminum-magnesium-manganese alloy roof panels, or laid with flexible asphalt, polymer-modified asphalt and other rolls. Considering the high cost of aluminum-magnesium-manganese alloy roof panels, flexible waterproof rolls are generally used. However, this flexible waterproof roll brings troubles to the fixation of solar photovoltaic panels. Therefore, a device is urgently needed to solve the problem of laying solar photovoltaic panels on the flexible roof of steel structure industrial plants. Utility Model Content

[0025] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0026] The terms such as "upper", "lower", "left", "right", "middle", etc. used in this application are usually used to facilitate intuitive understanding by comparing with the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product. Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be regarded as the scope of this application.

[0027] The utility model provides a fixing device for photovoltaic panels on steel structure roofs, such as Figures 1 to 4 As shown, the steel structure roof generally includes a purlin 1 arranged on the top surface of the steel structure house, a corrugated steel sheet 2 is laid on the top surface of the purlin 1, a vapor barrier 3 is arranged on the top surface of the corrugated steel sheet 2, a waterproof layer 5 is covered on the top surface of the vapor barrier 3, and a thermal insulation layer 4 is filled between the vapor barrier 3 and the waterproof layer 5. This is the existing steel structure roof structure composition well known to those skilled in the art and will not be described in detail here. In order to install photovoltaic panels on this steel structure roof, at least two groups of support components are set, each group of support components includes at least one first pillar 6 and a second pillar 7, the number of the first pillar 6 and the second pillar 7 is the same, and one end of the first pillar 6 and the second pillar 7 passes through the waterproof layer 5, the thermal insulation layer 4, and the vapor barrier 3 and is staggered and fixed in the groove of the corrugated steel sheet 2. The first pillar 6 and the second pillar 7 are fixed on the corrugated steel sheet 2, so that the first pillar 6 and the second pillar 7 are relatively stable. A first support rod 9 is provided between the first pillar 6 and the second pillar 7 of adjacent support assemblies away from the end of the corrugated steel plate 2. A second support rod 10 is provided between the first pillar 6 and the second pillar 7 of each group of support assemblies away from the end of the corrugated steel plate 2. The first support rod 9 and the second support rod 10 are in a grid-like structure, and the photovoltaic panels are fixedly placed thereon. The grid-like structure of the first support rod 9 and the second support rod 10 further enhances the overall stability of the fixing device of the present application, making the fixed placement of the photovoltaic panels more reliable and stable.

[0028] Preferably, in order to prevent the first pillar 6 and the second pillar 7 from passing through the waterproof layer 5 and causing damage to the waterproofing of the waterproof layer 5, the pillar waterproof layer 8 is coated on the outer periphery of the lower part of the first pillar 6 and the second pillar 7, so that the lower part of the pillar waterproof layer 8 extends to the waterproof layer 5 on the outer periphery of the first pillar 6 and the second pillar 7, thereby avoiding water leakage of the steel structure roof caused by the first pillar 6 and the second pillar 7.

[0029] Preferably, since the photovoltaic panels are usually arranged at an inclination, in order to meet the requirement of the inclined arrangement of the photovoltaic panels, the length of the first support 6 is greater than the length of the second support 7 .

[0030] Preferably, since the steel structure roof is generally inclined at a certain slope for drainage purposes, the first pillar 6 and the second pillar 7 are arranged along the inclined direction of the steel structure roof, and the first pillar 6 is located above the second pillar 7 .

[0031] Preferably, in order to facilitate the installation and fixation of the first pillar 6 and the second pillar 7, the bottom of the first pillar 6 and the second pillar 7 are provided with a fixing seat 11, and the fixing seat 11 on the periphery of the first pillar 6 and the second pillar 7 is evenly distributed with at least three fixing holes 1101. In this way, during construction and installation, fixing bolts or screws pass through the fixing holes 1101 and are threadedly connected with the corrugated steel plate 2 to fix the first pillar 6 and the second pillar 7 to the corrugated steel plate 2.

[0032] Optionally, the first support 6 and the second support 7 can be made of square steel pipes or round steel pipes, which is convenient for material selection and low in cost. Meanwhile, the fixing seat 11 can be designed to be square or round.
