Steel construction systems
Steel construction is the main steel structure, was one of the main types of structures.
Steel is one of more general structural forms in modern architecture. China was among the first to use iron manufacture of load-bearing structures of the country, as far away as the reign (246-219 BC), had already made simple iron structure, while Western countries in the 17th century began to use metal load-bearing structure. 3-6 century AD, smart and industrious people chained iron chain suspension bridges built, the famous luding bridge on the dadu River in Sichuan province, Yunnan's bridge and the bridge in Guizhou province, are early examples of iron-bearing structure in China.
Although the early Iron structures in China had made remarkable achievements, but because of the more than 2000-year feudal system bound, science was not developed, so has long remained at the building level of iron. Until the late 19th century, began using modern steel structure in our country. After the founding of new China, the great advance in the application of steel structure, both in terms of quantity or quality are far more than in the past. In design, and manufacturing and installation, technology aspects are
reached has high of level, master has various complex buildings of
design and construction technology, in country has built has many scale
huge and structure complex of steel plant, and big span steel civil and
the railway bridge,, China of here steel roof trusses, Beijing and
Shanghai, to of stadium of steel network frame, Shaanxi Qin Shi Huang Ma
helpers Gallery of three hinge steel arch frame and Beijing of nest,.
Characteristics of steel structure engineering
1, steel structure weight is light
2, the higher the reliability of steel structures
3, steel anti-vibration (shock), good impact resistance
4, higher levels of the industrialization of the manufacture of steel structures
5, steel can be used to quickly assemble
6, steel interior space
7, easy sealing structure
Advantage steel structure engineering
Seismic
sex: lower Villa of roofing mostly for Po roofing, so roofing structure
basically used of is by cold bent steel component made of triangle type
roof trusses system, light steel component in seal finished structural
plate and the gypsum board zhihou, formed has very solid of "Board rib
structure system", this structure system has more strong of seismic and
the resistance level Dutch contains of capacity, applies Yu seismic
intensity for 8 degrees above of area.
Wind resistance: the steel structure construction of light weight, high strength, high rigidity and deformation capability. Weight is only one-fifth of brick-concrete structure of buildings, Hurricane resistance of 70 meters per second, so that lives and property can be effectively protected.
Durability: light steel structure housing system consisting of cold-formed thin-walled steel structure used in all components, steel using Super anti-corrosion and high strength cold-rolled galvanized steel manufacturing, effective way to avoid corrosion of steel plate in the process of construction and use of effects, increase the service life of the light weight steel members. Structural life of 100 years.
Insulation: insulation glass wool, and has excellent thermal insulation effect. External wall insulation Board, effectively avoid the walls of "cold bridges" phenomenon, better thermal insulation effect is achieved. R15 100mm thick insulation cotton thermal resistance equivalent to 1M thick brick walls.
Sound insulation: is an important index for assessing residential sound insulation and installation of light gauge steel system Windows are made of hollow glass, good sound insulation, sound insulation up to 40 DB or more; consists of light-gauge steel, insulating materials consisting of gypsum board wall, its effectiveness can be up to 60 DB.
Health: dry construction, reducing environmental pollution caused by the waste, steel materials can be recycled 100%, most of the other supporting material may also be recycled, complies with current environmental protection awareness; all material for green building materials, meet environmental requirements, are good for health.?
Comfort: light steel wall with more energy efficient systems, respiratory function, adjustable indoor air humidity; roof ventilation function enables formed over the flow of air inside the room, guaranteed roof ventilation and thermal requirements.
Fast: all dry application, from the ambient seasonal effects. A 300 square meters of the building, only 5 workers 30 days can be completed from the Foundation to the decoration of the whole process.
Environmental protection: the materials can be recycled 100%, truly green and pollution-free.
Energy-saving: using energy efficient wall, good effect of heat insulation, sound insulation, 50% energy efficiency standards can be achieved.
