It is a structure mainly made of steel. It is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. Each component or part is usually connected by welds, bolts or rivets. It is one of the main types of building structures. Because of its light deadweight and simple construction, it is widely used in large factories, bridges, stadiums, super high-rise buildings and other fields.
Seismic resistance: most of the roofs of low rise villas are pitched roofs, so the roof structure is basically a triangular roof truss system made of cold-formed steel members. After sealing structural plates and gypsum boards, light steel members form a very solid "plate rib structure system", which has a stronger seismic resistance and resistance to horizontal loads, It is applicable to areas with seismic intensity above 8 degrees.
Wind resistance: steel structure building has light weight, high strength, good overall rigidity and strong deformation resistance. The deadweight of the building is only one fifth of that of the brick concrete structure, which can withstand the hurricane of 70 meters per second, so that life and property can be effectively protected.
Durability: The residential structure of light steel structure is composed of cold-formed thin-walled steel component system, and the steel skeleton is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the impact of corrosion of steel plate during construction and use, and increases the service life of light steel components. The service life of the structure can reach 100 years.
Thermal insulation: the thermal insulation material used is mainly glass fiber cotton, which has good thermal insulation effect. The thermal insulation board used for the external wall effectively avoids the "cold bridge" phenomenon of the wall and achieves better thermal insulation effect. The thermal resistance of R15 insulation cotton with a thickness of about 100mm can be equivalent to a 1m thick brick wall.
Sound insulation: the sound insulation effect is an important indicator to evaluate the housing. The windows installed in the light steel system are all made of insulating glass, which has a good sound insulation effect. The sound insulation is more than 40 decibels; The wall composed of light steel keel and thermal insulation material gypsum board has a sound insulation effect of up to 60 decibels.
Health: dry construction can reduce the environmental pollution caused by waste. The steel structure materials of houses can be 100% recycled, and most of other supporting materials can also be recycled, which conforms to the current environmental awareness; All materials are green building materials, which meet the requirements of ecological environment and are conducive to health.
Comfort: The light steel wall adopts an efficient energy-saving system, with breathing function, which can adjust the indoor air humidity; The roof has ventilation function, which can form a flowing air room above the roof to ensure the ventilation and heat dissipation requirements inside the roof.
Fast: all dry construction, not affected by environmental seasons. For a building of about 300 square meters, it only takes 5 workers and 30 working days to complete the whole process from foundation to decoration.
Environmental protection: materials can be 100% recycled, truly green and pollution-free.
Energy saving: all of them adopt high-efficiency energy-saving walls, with good thermal insulation, heat insulation and sound insulation effects, which can reach the energy saving standard of 50%.
