The applicable scope of steel truss deck is applicable to both steel structure and concrete structure. First of all, because of the large amount of steel bars, the steel truss bears a large unsupported span. Therefore, for buildings with a span of more than 4.5 meters, it is beneficial to choose the steel truss deck, because it can make a large unsupported span. Thirdly, because there are many steel bars, which can bear great late load, the steel truss deck is more suitable for buildings with late load capacity above 1.5 tons. Also, it is quite suitable for industrial plants with low floors. This can avoid the drawback that steel truss floor slabs occupy a large number of cranes in high-rise buildings.
Steel deck realizes mechanized production, which is beneficial to uniform arrangement and spacing of steel rebar and uniform thickness of concrete protective layer, and improves the construction quality of steel truss deck. Assembled steel truss deck can significantly reduce the amount of steel binding on site, speed up the construction progress, increase the construction safety guarantee and realize civilized construction. Assembled templates and connectors are convenient to disassemble and assemble, can be reused for many times, saves steel, and meets the requirements of energy conservation and environmental protection. But also greatly improves the labor productivity and effectively reduces the product cost.
