Description

Technical Field

[0001] The utility model relates to the field of photovoltaic panel installation, in particular to a photovoltaic foundation structure used for a steel structure factory building. Background Art

[0002] Existing factories are generally located in relatively open areas, which have the advantages of large area and few obstacles, making them a high-quality and precious resource for photovoltaic power generation. Installing a photovoltaic system on the roof of a factory building can not only ensure a large amount of power generation, but also reduce the company's dependence on traditional energy, thereby reducing energy costs. However, existing industrial plants are generally steel structures. Due to their own structural characteristics, they are more sensitive to load changes. The existing installation generally installs the installation foundation on the purlin system of the plant. The purlin system has insufficient bearing capacity and cannot meet the needs of photovoltaic installation. At present, the common reinforcement method for installing photovoltaics on the roof of a steel structure plant is to remove the original roof and replace large-section purlins or increase the density of purlins. However, the replacement or density of purlins requires the removal of the roof, which is difficult to construct and requires a large amount of disassembly and assembly work, thereby increasing the installation cost of the roof plant and overlapping the construction period. Due to the removal of the roof, the normal production in the plant is also seriously affected. Summary of the invention

[0003] In view of this, the utility model proposes a photovoltaic foundation structure for a steel structure factory building, which transfers the bearing force to the load-bearing steel beams in the factory building, has no effect on the roof purlins, and does not need to reinforce the purlins, thereby improving safety and facilitating construction without affecting normal operations in the factory building.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The photovoltaic infrastructure for a steel structure factory building described in the utility model comprises an attached beam erected above the light steel roof of the factory building and corresponding to the steel beams in the house, and also comprises a connecting structure connecting the attached beam and the steel beam together, the connecting structure comprises a plurality of connecting units, an upper steel plate and a lower steel plate arranged at intervals along the length direction of the steel beam, the upper steel plate and the lower steel plate both corresponding to the steel beams in the upper and lower directions; each connecting unit comprises a pair of screws, a lower pressure plate passed through each of the screws and an upper clamping plate passed through the screws, the lower steel plate is located on the lower surface of the steel beam, the lower pressure plate is pressed on the lower flange of the steel beam in the house, and the lower pressure plate and the lower steel plate are fixed to the lower part of the screw by nuts; the upper clamping plate is fixedly connected to the upper flange of the steel beam; each pair of screws passes through the light steel roof upward, the upper steel plate is located above the light steel roof and fixedly connected to each pair of screws, and the attached beam is fixed to the upper steel plate by a plurality of connecting members.

[0006] The beneficial effect is: the utility model connects the attached beam and the steel beam inside the house into a whole through the upper steel plate, the lower steel plate and multiple connecting units. The attached beam is located above the roof. The load borne by the attached beam avoids the roof and is directly transmitted to the steel beam (the steel beam is the load-bearing beam of the factory building). It has no effect on the roof purlins of the factory building, and there is no need to reinforce the roof purlins. No welding is required during construction. It has high safety and low project cost, which reduces the cost of photovoltaic installation.

[0007] Preferably, the connecting piece is a U-shaped bolt with an opening facing downward, the U-shaped bolt is arranged on the attached beam, and the threaded section of the U-shaped bolt passes through the upper steel plate downward and is fastened with a nut. The beneficial effect is that the attached beam is connected to the upper steel plate by the U-shaped bolt, the installation is simple and convenient, and the fixing effect of the attached beam can be guaranteed.

[0008] Preferably, each of the screw rods is provided with a waterproof pad, which is fastened to the light steel roof by a nut screwed on the screw rod, and the bottom surface of the waterproof pad is adhered to the light steel roof. In actual installation, the waterproof pad is preferably a rubber gasket. The rubber gasket is bonded to the light steel roof and fastened to the light steel roof by a nut, which effectively ensures the waterproof performance of the light steel roof and prevents water leakage in the factory.

[0009] Preferably, the lower pressure plate is an L-shaped structure; the upper clamping plate is a U-shaped structure, the nut on the screw fastens the upper clamping plate to the bottom of the roof purlin, the upper flange of the steel beam is located in the U-shaped groove of the upper clamping plate, and the upper clamping plate and the upper flange are fixed together by fastening bolts, effectively ensuring the connection reliability.

[0010] Preferably, the photovoltaic infrastructure also includes photovoltaic purlins spaced apart on the attached beams. In actual projects, in order to meet the needs of the photovoltaic system on the factory roof, there are often multiple attached beams spaced apart, and two or more photovoltaic purlins can be spaced apart between every two attached beams to provide an installation foundation for the installation of photovoltaic panels.

[0011] Compared with the prior art, the utility model sets up an attached beam above the roof. The attached beam is not connected to the roof. The attached beam is connected to the steel beam in the house through an upper steel plate, a lower steel plate, multiple connection units to form a whole. The attached beam is located above the roof.
