Tianwei | On the Development Trend of Steel Structure Assembled Residential Buildings
Light steel houses are durable and cost-effective.
The service life of the main structure of the light steel house is 90 years, which is three times that of the traditional house.
Light steel houses are very adaptable, both in the cold northeast and hot Hainan, but the structure of the buildings is different.
The main materials needed for building the house are all produced in the factory, and the raw materials are processed by mechanical equipment, which is highly efficient, low in cost, and well guaranteed in quality.
Compared with developed countries, China has a large gap in green buildings with steel structures.
In case of demolition, the light steel house can be divided into many parts, which can be reinstalled after being transported to a new location.
This is because the components of the light steel house are produced in the factory and can be directly assembled by workers after being transported to the site, so the time is very short.
The comprehensive cost performance ratio of the house is better than that of the traditional frame structure.
It can not only be recycled and reused, reduce the discharge of construction waste, but also promote the development of housing industrialization, and promote the upgrading and upgrading of construction components.
The light steel house is very safe, and the earthquake resistance is 9 degrees.
It is widely used in large-span industrial plants, standard workshops, coal sheds and warehouses.
Because these parts are connected by screws and connectors, installation and disassembly are very simple.
It is mainly used in low rise (3 storeys and below) and multi-storey buildings (6 storeys and below).
In China, the steel used for steel structure is less than 6%, and the proportion of steel structure construction area in the total construction area is less than 5%.
Steel structure residence is a recyclable building structure in the city.

Our traditional houses have become dangerous in 30 years.
This is because the steel keel is light, strong, high-quality building materials, and has good ductility and toughness.
The light steel house is movable.
It is a very mature structural system.
Although there are a large number of light steel residential areas in earthquake stricken areas such as Sichuan and Gansu, in general, it is difficult to promote light steel residential areas, which has been in a tepid state.
The main reason for the slow development in China is that the building envelope materials and supporting facilities of precast steel structure residence are not perfect, which can not really form a complete precast system.
The existing wall material performance and installation method can hardly meet the requirements of steel structure residence in terms of thermal insulation, ventilation, fire protection and durability.
(hereinafter, light steel structure is referred to as cold-formed thin-walled steel structure system) In China, enterprises introduced light steel structure at the beginning of this century, which has been applied in commercial real estate, tourist attractions, rural self built houses and other fields.
This policy will also stimulate the intelligent residence.
From the perspective of main materials, steel will not become worm or rotten wood with the passage of time.
It has a history of more than 30 years in North America and has been widely used.
The performance of light steel structure is far better than that of traditional brick concrete residence, which has been criticized for its lack of seismic resistance and comfort.
The production of light steel houses is highly industrialized, mechanized and commercialized.
Most of these equipment are imported with foreign advanced technology, and many new housing products of large enterprises have international quality.
This article originates from the network.
The cold-formed steel structure system used in the new light steel building is a multi ribbed slab wall system.

It can prevent typhoon of level 12, and the roof bears 1.5 meters of snow.
The system bears the gravity load with “ribs” and requires that the gravity load is directly transmitted by aligning the upper and lower parts, and the “slab” (various shear wall panels) is used to resist the lateral force generated by seismic load and wind load.
In developed countries such as the United States and Japan, the amount of steel used for steel structures has accounted for more than 30% of the steel output, and the building area of steel structures has accounted for more than 40% of the total building area.
In 2011, the Ministry of Housing and Urban Rural Development issued the Technical Specification for the Construction of Low rise Cold formed Thin walled Steel Buildings (hereinafter referred to as the Low rise Specification), which provides a basis for the design and acceptance of low rise light steel residences of 3 storeys and below.
All kinds of houses are carefully designed by designers, and there are many styles to choose from.
A Brief Talk on the Development Trend of Steel Structure Precast Residence The steel structure precast residence is a factory production.
The construction of light steel houses is very fast, and the construction period of a 200 ㎡ house is within one month.
The Technical Specification for Cold formed Thin walled Steel Multistory Residential Buildings applicable to light steel residences of 6 storeys and below is currently under preparation.
Now light steel houses have come into our lives.
It can be recycled after several years of demolition, which is very environmentally friendly and economical.
Light steel houses have beautiful and diverse shapes.
Now let’s see what advantages light steel houses have.
The steel structure plant built by Blue&Brief Shanxi Tianwei Steel Structure Engineering Co., Ltd.
The steel structure precast residence is conducive to saving construction costs, and the steel structure precast residence is conducive to building energy-saving buildings.
has the advantages of light overall, saving foundation, using less materials, low cost, short construction period, large span, safety and reliability, beautiful appearance, stable layout, etc.
80% of the materials of light steel buildings can be recycled.
