Seismic performance of Foshan steel structure project: the roofs of low rise villas are mostly sloping roofs, and the roof structure is basically triangular roof truss system with cold-formed steel members. After the structural board and gypsum board are sealed, the light steel components form a very strong "slab reinforcement structure system". The structure system has strong seismic performance and horizontal load resistance, which is suitable for the area with seismic intensity above 8 degrees.
Wind resistance performance of Foshan steel structure: light weight, high strength, good overall stiffness, strong deformation capacity. The self weight of the building is only one fifth of that of the brick concrete structure, which can resist the hurricane of 70 meters per second and effectively protect the life and property.
Durability: the residential structure of light steel structure adopts cold-formed thin-walled steel member system, and the steel skeleton adopts super anti-corrosion high-strength cold-rolled galvanized sheet, which can effectively avoid the influence of steel plate corrosion in the process of construction and use, and improve the service life of light steel components. The service life of the structure can reach 100 years.
Insulation: glass fiber cotton is the main insulation material, with good insulation effect. The use of thermal insulation board can effectively avoid the phenomenon of "cold bridge" and achieve better thermal insulation effect. The thermal resistance of R15 insulation cotton with thickness of about 100 mm is equivalent to that of brick wall with thickness of 1 m.
Sound insulation: sound insulation effect is an important index to evaluate residential buildings. The windows installed in the light steel system are all made of insulating glass, which has good sound insulation effect, and the sound insulation effect is more than 40dB; the sound insulation effect of the wall composed of light steel keel and thermal insulation material gypsum board can reach 60dB.
Health: dry construction can reduce the environmental pollution caused by waste. The steel structure materials of the house can be 100% recycled, and most other supporting materials can also be recycled, which is in line with the current environmental awareness; all materials are green building materials, which meet the requirements of the ecological environment and are conducive to health.
Comfort: the light steel wall adopts high-efficiency energy-saving system, with breathing function, which can adjust the indoor air drying and humidity; the roof has ventilation function, which can form a flowing air chamber above the house, ensuring the ventilation and heat dissipation requirements of the roof.
Fast: all dry construction, not affected by environmental seasons. A 300 square meter building with only 5 workers can complete the whole process from foundation to decoration in 30 working days.
Environmental protection: materials can be 100% recycled, truly green and pollution-free.
Energy saving: the use of efficient energy-saving wall, thermal insulation, sound insulation effect is good, can reach 50% of the energy saving standard.
