The era of light steel villas has come!

"Thirteenth Five-Year Plan of Action for Assembly Buildings" points out that by 2020, the proportion of assembly buildings in new buildings will reach more than 15%, and the key areas will reach more than 20%. The whole assembly building industry has shown a vigorous development trend. In all aspects, it has become a general trend to vigorously promote the development of assembly building and construction industrialization. At present, assembly building accounts for only about 3% of the new building area in China, and the target growth space is large.

Different from the traditional brick-concrete residential building, all the building components of light steel villas are produced in factories. Precision computer-aided manufacturing is used in the production process. The dimensions of building components are strictly checked. Compared with manual manufacturing, machine manufacturing is more refined. After the production of all relevant building components is completed, these components will be shipped to the construction site together, and then constructed by the construction personnel. This construction method of light steel villas has broken the traditional construction method of "Qin bricks and Han tiles" which has lasted for thousands of years, and completely subverted the traditional buildings by "standardization" of building components and "industrialization" of construction methods.

Compared with the traditional buildings with long construction period, high labor cost and heavy pollution, the construction method of light steel villas is not only high construction efficiency and low labor cost, but also more elaborate construction process, which is more conducive to ensuring the quality of buildings. In the construction process, without a large number of construction teams, 3-5 people can easily complete the construction task of light steel villas, only half a month can be completed, greatly saving human, material and financial resources.

The new construction method of light steel villas not only has fast construction speed and low cost, but also plays a very good role in environmental protection. Because in the construction process of light steel villas, there will be no large amount of harmful waste, no damage to the vegetation around the construction, and it fully conforms to the national standard of green environmental protection building.

Light steel villa, let you have a better family life!

Third, CCTV interpretation ushered in spring! New Standard of Light Steel Villa Industry in China!

The output of China's iron and steel industry has been in the forefront of the world, but the proportion of steel used in the construction industry is far lower than that of developed countries. The construction technology of low-rise residential buildings with light steel structure conforms to the national industrial orientation of the construction industry. The project of light steel structure residential buildings has aroused strong response and concern from the industry and relevant departments of governments at all levels. It is supported by relevant government departments at all levels in policy and technology.

The Premier presided over the executive meeting of the State Council and decided to vigorously develop steel structure assembly building and promote industrial restructuring and upgrading, so light steel assembly building has become a tuyere industry and entered thousands of households.

Light steel villas are beautiful and generous, environmentally friendly and comfortable. Their service life can reach 100 years. Some friends expressed their disbelief that they are beautiful and generous. It is undeniable that they are environmentally friendly and comfortable. But who can prove that the building has a lifetime of 100 years?

There is no doubt about it. After all, the life span of our traditional brick-and-concrete residence is about 50 years, which gives us a preconceived feeling. Subconsciously, it is impossible for ordinary buildings to have a life span of 100 years. Today, I'd like to introduce more than 100 young steel villas in foreign countries to you, and correct the name of light steel villas.

U.S.A

Assembled housing in the United States prevailed in the 1970s. In 1976, the National Industrial Housing Construction and Safety Act was promulgated. A series of strict industry standards have been used up to now.

Britain

After World War II, in order to solve the housing shortage problem, Britain, like other European countries, has adopted the industrialized way to build a large number of houses. After the 1960s and 1970s, there has been a trend of diversification in the housing structure system: wood structure, steel structure, reinforced concrete structure, etc., which has been used up to now.

Germany

Germany is one of the countries with the fastest reduction in building energy consumption in the world. In recent years, zero energy consumption has been proposed. The assembled buildings in Germany mainly adopt composite slabs and concrete structure system, which has good durability.

Japan

Japan put forward the concept of assembly building in the 1960s and 1970s. Knowing that the housing production system launched in the 1990s to meet different needs has undergone a continuous evolution and improvement process from standardization, diversification, industrialization to intensive and informatization.

France

France is one of the earliest countries in the world to implement the assembly building. The assembly building in France is mainly composed of the assembly concrete, supplemented by steel and wood structures, and operated by dry method. The structural components are separated from the equipment and decoration works, so as to reduce the pre-embedding, and the quality of production and construction is high. The assembly rate has reached 80%.

Singapore

Singapore is recognized as a country with a good solution to the housing problem in the world, accounting for more than 80% of the total number of residential buildings in the country. With the design as the core, the industrialization of the design and construction process has been integrated with each other, and the assembly rate has reached 70%.

We can see that the proportion of light steel villas in developed countries such as Europe and the United States, or in countries with earlier development of light steel villas, is much higher than that of us. According to the statistics of the American Industrial Housing Association, in 2001, the number of assembled houses in the United States has reached 10 million units, and nearly 20 years later, the number has doubled.

The Technical Standard for Cold-formed Thin-walled Steel Multi-storey Residence, which was implemented on January 1, 2019, is applicable to multi-storey light steel residences with six stories and below, and has supplemented the technical standards in this field. With the publication and implementation of the new standard, the spring of multi-storey assembled light steel residences is coming.

CCTV calls light steel residential buildings the future direction of construction. CCTV News Channel reports: At present, China's construction industry vigorously promotes the building model called assembly building. In the next ten years, the proportion of the area of assembled buildings in new buildings will reach 30%. The continuous improvement of policies and standards will make the light steel assembly industry develop better and better.
