(1) high-rise steel technology. Were used according to design requirements for building height and frame, frame support, and giant tube frame structure, its components can be steel, steel reinforced concrete or steel concrete. Good ductility lightweight steel components, steel can be welded or rolled steel for ultra-story building was built; steel reinforced concrete structures stiffness, fire performance, suitable for high-rise buildings or bottom structure; simple steel concrete construction, only for the column structure.
(2) space steel structure technology. Space steel structure, light weight, stiffness, attractive appearance, construction speed. Steel rod with a ball for the node plate rack, multi-variable cross-section grid and networks such as Shell is the largest amount of space steel structure type. Spatial rigidity, low steel consumption advantages. In addition to the grid structure, spatial structure there are large cross-cable structure, cable-membrane structure.
(3) light steel technology. With the new structure made of light color steel wall and roof envelope forms composed. By the more than 5mm steel plate welded or rolled H-beam wall large section of thin-walled beams and roof purlins, light steel round bar made of a flexible system and high-strength bolted support system composed of column spacing from 6m to 9m, span up 30m or more, up to the height of ten meters, and set light hanging IV. Steel consumption 20 ~ 30kg/m2. The design has been standardized procedures and specialized production enterprises, product quality, fast installation, light weight, low investment, construction subject to seasonal restrictions, applicable to all kinds of light industrial plants.
(4) steel concrete composite structures technology. With steel or steel and concrete structures composed of management beams, columns bearing structure of steel-concrete composite structures, in recent years, a growing range of applications. Combination of both structural steel and concrete advantages of both large overall strength, rigidity, good seismic performance, when using outsourcing concrete structure, more fire-resistant and has good corrosion resistance. Combination of steel structural members in general can reduce the amount of 15 to 20%. Composite slabs and steel concrete structures, but also has less support mold or why he did not die, the advantages of fast and convenient construction, the promotion of greater potential. Suitable for larger loads with high-rise buildings or multi-frame beams, columns and floor, columns and floor and other industrial buildings.
