In China, energy-saving buildings account for more than 50% of existing urban buildings, 75% of new urban residential buildings are designed to be energy-saving, and more than 1 million square meters of passive low-energy buildings are built. Green building standards are fully implemented in new urban buildings, and green buildings account for more than 50% of new urban buildings.
At present, the country is vigorously promoting green building, energy conservation and environmental protection, recycling and housing industrialization, industrialization, for all levels of government and real estate companies, investors pay attention to and promote the new industry. At present, China’s residential light steel structure accounted for less than 5%, compared with almost more than 50% of foreign developed countries, China is still in its infancy, but the light steel structure technology has now become mature, light steel villa has a lot of space for development.
Due to the strengthening of environmental awareness and wood shortage and other factors, many countries such as the United States, Japan, Britain, Australia and so on, are actively promoting the application and development of low-rise light steel villas.
Many countries in Europe and the United States, as early as in the 1960s, put forward the concept of “rapid installation of prefabricated housing”, but because the market is not mature, has not been very good development. By 1987, high-strength cold-formed thin-wall steel structures had emerged, and the Joint Australian/New Zealand specification AS/NZS4600 for cold-formed structural steels was published for implementation in 1996. This steel has a high bearing capacity, only 1/3 of the weight of wood compared to the same bearing capacity, and has a galvanized surface that can last up to 75 years without major repairs.
The architectural forms of housing are varied, and the traditional buildings are mainly brick and reinforced concrete structures. Material space utilization is low, difficult to dismantle, low reuse rate, but also not environmental protection. Human housing is constantly evolving, in the future, the construction of rapid light steel housing will be the new favorite of the future village buildings, will also represent the residential structure and development trend.
The construction process adopts dry operation construction, a 300 square meters house 5 workers 30 days can be completed the main building, exterior wall style is diverse, less material waste, diverse shapes.
This light steel villa without beams and columns, high space utilization, materials, labor costs can save a lot. This light steel villa structure mainly consists of four parts: light steel structure, wall structure, floor structure and roof structure.
Light steel villa has a long life, light steel keel galvanized steel, 3D customized board wall high density, high pressure resistance, not easy to deformation, can ensure a hundred years of the main body is not bad, but also in line with the government’s concept of green building.
Light steel villa construction time and labor saving, the main body can be built on the layout of water and electricity. More than 95 percent of low-rise residential buildings in continental North America are built of wood or light steel. As early as the eighties, light steel villa was introduced into our country, but it has not been popularized, the main reason is that the domestic technology is not mature, is not accepted by the public. In 2004, foreign advanced light steel and EPS combined use of light steel villa imported from the United States, has been extremely improved and used.
Compared with reinforced concrete structure system, the cost of light steel villa system is slightly lower or the same, so it has strong competitiveness. Considering the long-term use, development trend and environmental protection requirements, light steel villa development prospects, market demand, will gradually become a new housing market “selling point”.
