Light steel structure is a young and vital steel structure system, which has been widely used in general industrial and agricultural, commercial and service buildings, such as office buildings, villas, warehouses, stadiums, entertainment, tourist buildings and low and multi-layer In the fields of residential buildings, etc., it can also be used in areas such as old buildings, renovation, reinforcement and lack of building materials, inconvenient transportation areas, tight construction schedules, and movable demolition buildings. It is favored by the owners and has the following characteristics:
1. Shock resistance:
Most of the low-rise villas are sloping roofs. Therefore, the roof structure basically adopts a triangular roof truss system made of cold-formed steel members. The light steel members form a very strong after sealing the structural plates and gypsum boards." The ribbed structural system, which has a stronger ability to withstand earthquakes and resist horizontal loads, and is suitable for areas with a seismic intensity of 8 degrees or more.
2. Wind resistance
The steel structure has light weight, high strength, good overall rigidity and strong deformation ability. The building's own weight is only one-fifth of the brick-concrete structure, which can withstand hurricanes of 70 meters per second, so that life and property can be effectively protected.
The light steel structure residential structure is composed of cold-formed thin-walled steel component system. The steel bone is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the influence of corrosion of the steel plate during construction and use, and increases the service life of the light steel component. The structural life can reach 100 years.
4. Thermal insulation
The thermal insulation material used is mainly made of glass wool, which has good thermal insulation effect. The insulation board of the outer wall effectively avoids the "cold bridge" phenomenon of the wall and achieves better insulation effect. The thermal resistance of R15 insulation cotton with a thickness of about 100mm can be equivalent to a brick wall of 1m thick.
5. Sound insulation
The sound insulation effect is an important indicator for evaluating the house. The windows installed in the light steel system are all insulated glass, with good sound insulation and sound insulation of more than 40 decibels. The wall made up of light steel keel and thermal insulation gypsum board can have high sound insulation effect. 60 decibels.
The light steel wall adopts an energy-efficient system, has a breathing function, and can adjust the indoor air dry humidity; the roof has a ventilation function, which can form a flowing air between the interior of the house to ensure the ventilation and heat dissipation requirements inside the roof.
All dry work is carried out and is not affected by the environmental season. A building of about 300 square meters, only 5 workers and 30 working days can complete the whole process from foundation to decoration.
8. Environmental protection
The material can be 100% recycled, truly green and non-polluting.
9. Energy saving
All adopt high-efficiency energy-saving walls, which have good insulation, heat insulation and sound insulation effects, and can reach 50% energy-saving standards.
