The advantages of steel structure in engineering application

Eliminating the quality defects of steel structure engineering is a huge system engineering. Full attention should be paid to the various stages of the construction process, the parties involved in the construction process, the design and construction process and links. At the same time, the promotion and application of new technology and new process of steel structure should also increase propaganda efforts, so that we can feel the importance of new steel structure engineering in people's life and work relationship, control quality defects, eliminate the maximum strength.

Earthquake: the roofs of low-rise villas are slope roofs, roof structure is basically the use of cold-formed steel triangular trusses, in the sealed end structural plate and gypsum board light steel components, forming a strong "plate structure", this structural system of seismic and horizontal load resistance ability, suitable for more than 8 degrees of earthquake intensity in the region.

Wind resistance: steel structure light weight, high strength, good overall stiffness, strong deformation ability. The weight of the building is only 1/5 of the brick and concrete structure, which can resist the hurricane of 70 meters per second and effectively protect life and property. Durability: Light steel structure houses are made of cold-formed thin-wall steel members. The steel frame adopts super corrosion resistance and high strength cold rolled galvanized sheet, which can effectively avoid the corrosion of steel plate during construction and operation, and improve the service life of light steel members. The structural life can reach 100 years.

Thermal insulation material: mainly glass wool thermal insulation material, good thermal insulation effect. Using external wall thermal insulation board can effectively avoid the phenomenon of "cold bridge" on the wall and achieve better thermal insulation effect. Use 100mm thick R15 insulation cotton thermal resistance is equal to 1m thick brick wall. Sound insulation effect: sound insulation effect is an important index to evaluate housing. Windows installed in light steel system all hollow glass, sound insulation effect is good, sound insulation up to 40 dB, and sound insulation effect of wall light steel keel gypsum board and insulation up to 60 dB.

Health: dry operation construction, reduce environmental pollution, housing steel structure materials can be 100% recycled, other supporting materials can also be mostly recycled, in line with the current environmental awareness; All materials are green building materials, which meet the requirements of ecological environment and are beneficial to health. Comfort: light steel wall adopts high efficiency energy saving system, has breathing function, can adjust the indoor air dryness and humidity. The roof has a ventilation function that allows indoor air to flow to ensure ventilation and heat dissipation within the roof.
