Photovoltaic solar power industry is a renewable resource, it is the technology of converting solar energy into the required electric energy, and it is the important symbol of our new energy industry. With the wide use of new energy, photovoltaic solar powered stent has been widely used in China, Solar mounting racks the quality of solar stent has been widely concerned. The solar powered bracket is usually divided into three kinds: concrete bracket, light steel structure solar powered bracket and aluminum alloy bracket three kinds, the concrete bracket weight is big, the request is high to the use environment, this kind of structure has been eliminated gradually. Solar powered support for large photovoltaic energy projects is a steel structure bracket, it has strong bearing capacity, good corrosion-resistant effect, recyclable, relative to the other two kinds of solar stent, aluminum alloy stent light weight, good corrosion effect, holding time is longer, but not suitable for large photovoltaic solar energy industry.
First, solar stent welding, it is not high requirements for angle steel, the connection is not high cost, the connection effect is very good, more solid, the scope of use is also very common. This type of connection is prone to corrosion, after-sale maintenance costs high, for the field welding process, will cost a lot of costs, welding connection is not beautiful, the process is slightly rough, not in line with people's aesthetic needs.
Second, solar powered stent assembly, Solar mounting racks it is connected by a hinged way, trough steel finished bracket as a splicing bracket, the site does not need to be welded, can be directly assembled on the spot by bolts, faster installation speed, beautiful and generous, more durable, it is easy to adjust, the production of this kind of solar stent mainly makes the connection between the channel convenient, firm , which can be easily disassembled.
With the rapid development of China's green economy, monocrystalline silicon/polycrystalline silicon photovoltaic power generation and thin film BIPV technology is maturing. Compared with other structures, the steel structure has great advantages in the use of function, design, Solar mounting racks construction and comprehensive cost. Therefore, it is of great significance to actively develop and produce new type of steel structure PV bracket system instead of the existing angle steel bracket system.
Lightweight structural steels: lightweight structural steels mainly refer to round steel, small angle and thin-walled steel. When the angle steel is used as supporting member, the strength of the steel can be used better and the whole bracket is installed, but the deformation is relatively large when used as bending and compression member. At present, the national standard of angle steel relative to the solar bracket, the optional model is not much, so need more small angle steel models to adapt to the current rapid development of the solar market. The purlin members of the thin-walled section steel are generally made of wall thickness 1.5-5mm Thin steel plate, after cold bending or cold rolled into a variety of different cross-section form and size of thin-walled steel products.
