In the bright color, after two years of online posting experience, at least some changes from the personal point of view, have a deeper understanding of steel structure design. Xiaobian also wrote down this little experience and gave it to those in need.
Steel structure type of billboard
There are three types of steel structure: steel structure, stainless steel structure and aluminum alloy structure.
Advantages and disadvantages of
Steel structure: Generally speaking, the steel structure refers to the steel structure without any special instructions. It is mainly welded with angle steel, bending moment steel, I-beam or channel steel. This kind of structure has high strength, strong bearing capacity and high wind resistance. It is the most widely used structure with the highest cost performance.
Stainless steel structure: stainless steel structure is more expensive than steel structure, and its bearing strength and wind resistance are worse than steel structure. Its biggest advantage is beautiful, and its smoothness and beauty require a higher place than steel structure in general, and it is used in places with little wind resistance.
Aluminum alloy structure: this structure is more similar to stainless steel structure, with high cost and poor strength, but the biggest feature is fast construction and beautiful appearance. Generally, it is also suitable for occasions with high requirements and low wind pressure resistance.
Design requirements for steel structure of billboard
First of all, what is the structural nature of billboard installation? Wall, curtain wall, steel frame, roof or others
Then, according to the design code of steel structure, the bearing capacity of the installation surface, the number of steel structure and the number of supporting points are calculated.
Generally, for the words below 2m, 40mm * 40MM * 4mm fillet welding can be used directly, or 30mm * 30MM * 3mm bending moment steel can be used. The word steel structure from 2m to 3.5m is made closer, and the galvanized angle steel of 40 * 40 * 4 is also fully used. If the luminous character is greater than 3.5m, it depends on the installation height, production process, luminous character weight and wind pressure resistance capacity, and whether angle steel or square tube is used. In general, the rectangular steel has a strong torsional resistance, so the structure of large-scale members can be considered.
