Light steel construction
Light steel structures are mainly used in load-bearing structures that do not bear large loads.Light H-beam steel (welded or rolled;Variable cross section or equal cross section) to make the door shape steel bearing, C, Z cold-formed thin-walled steel purlin and wall beam, or lightweight sandwich board for steel sheet roof, wall retaining structure, the adoption of high strength bolt, ordinary bolt and self-tapping screws and other fitting and sealing materials assembled low-rise and multi-layer prefabricated steel structure housing system.
Structure form
1, purlin: in light steel structure, most of the use of purlin system, so purlin is an important component.There are mainly the following types of purlins: solid web thin-walled steel purlins, open web purlins made of Angle steel and strap-plate, truss purlins.
2. Truss: The truss is the main load-bearing member in the roof structure. The form of the truss is triangle, trapezoid, shuttle, three hinged fish, etc., which can be made of Angle steel thin-walled steel, round pipe, square pipe, etc.
Monolayer and multilayer 3, steel, steel, steel bar with solid-web and lattice, multi-storey steel frame can effectively use of building space, reduce the height of the building, modelling concise and beautiful, neat component specifications, site installation, convenient and fast construction, is the main structure form, the structure of light use h-beam production more.
4, the grid: the grid has a space role, and beam plate, truss plane structure has the characteristics of good integrity, stiffness, can effectively withstand the earthquake and other dynamic loads.
The steel structure features：
1.Shock resistance:Low-level villa roof are mostly for the slope roof, so roof structure basically USES is made of cold bending steel components triangular roof truss system, light steel members in after sealing the structural plate and plasterboard, formed a very strong “rib plate structure system”, this kind of structure system have stronger earthquake and the ability to resist horizontal load,Suitable for seismic intensity of 8 degrees above the area.
2.Wind resistance: light steel structure building light weight, high strength, good overall rigidity, strong deformation ability.The self-weight of the building is only one fifth of the brick and concrete structure, and it can resist the hurricane of 70 meters per second, so that life and property can be effectively protected.
3.Durability: the light steel structure residential structure is composed of cold-formed thin-walled steel member system, and the steel bone is made of super anticorrosive and high-strength cold-rolled galvanized sheet, which can effectively avoid the influence of corrosion in the construction and use of the steel plate and increase the service life of the light steel member.The life of the structure is up to 100 years.
4.Thermal insulation: the thermal insulation materials used are mainly glass fiber cotton, which has good thermal insulation effect.The insulation board used for the external wall can effectively avoid the phenomenon of “cold bridge” on the wall and achieve better insulation effect.About 100mm thick R15 insulation cotton thermal resistance value can be equivalent to 1m thick brick wall.
5.Sound insulation: sound insulation effect is an important index of residential evaluation, light steel system installed Windows are hollow glass, sound insulation effect is good, sound insulation of more than 40 decibels;By light steel keel, insulation material gypsum board composition of the wall, its sound insulation effect can be as high as 60 decibels.
6.Health: dry construction, reduce the pollution caused by waste to the environment, housing steel structure materials can be 100% recycled, most of other supporting materials can be 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.
Comfortable: light steel wall adopts high efficiency and energy saving system, with breathing function, and can adjust indoor air dry and humidity;The roof has the function of ventilation, which can form the flow of air over the inside of the house, so as to ensure the ventilation and heat dissipation needs inside the roof.
7.Quick: all dry operation construction, not affected by the environmental season.A building of about 300 square meters, only 5 workers 30 working days can be completed from the foundation to the whole process of decoration.
8.Environmental protection: the material can be 100% recycled, truly green pollution-free.
9.Energy saving: all high efficiency energy-saving wall, heat preservation, heat insulation, sound insulation effect is good, can reach 50% of the energy saving standard.
