In recent years, the urbanization process in China is accelerating the development of the construction industry into the "fast track", however, the attendant, but it is construction waste to the city's air, water, soil, causing serious pollution. "Green Building" concept came into being. It is understood that, at present, green building has risen to national strategies, January 1, 2015 implementation of the "Green Building Evaluation Standard" on the rate of renewable energy alternatives put forward specific demands.
According to data provided by the relevant professional analysts, only in 2012, our construction waste generated reached 1.5 billion tons, is expected to 2018, construction waste processing capacity needed to reach 2.566 billion tons or more. "Every 10,000 tons of construction waste should take up 2.5 acres of land, estimated annual production of 15 million tons, China's annual construction waste will be an area of 37.5 acres, 38 West Lake landfill can do the same." Professionals said.
China Steel Structure Association Secretary General Liu Wanzhong said that at present, the development of China's construction industry, just to stay in the traditional way behind the extensive production, only to intensify the elimination of backward traditional concrete building mode, and vigorously promote "green energy" green building, in order to crack "construction waste siege" from the root of the dilemma. Steel housing itself has "light, fast, better and cheaper" feature, is highly representative of the green building, earthquake resistant buildings. Future green steel housing will undoubtedly become the development direction of domestic commercial residential construction.
Zhejiang Hangxiao Steel Structure Co., Ltd. is the first listed company. According to the vice president Hangxiao Sui presentation, building housed 30-story high-rise residential, concrete takes about two years, but with a new steel structure housing system needs only one year. This not only can greatly shorten the construction period, but also easy to project quality control. The duration of the reduction, quality assurance, bringing the cost of all aspects of corporate finance, human services, and other half. Thus, the cost of steel structure housing will draw traditional concrete houses. "Our goal is to achieve 'like making cars like a house built'." Sui said.
Statistics show that in terms of saving supplies steel building excellence, compared with concrete buildings, can reduce the amount of sand, cement used for about 40% of carbon dioxide emissions than conventional concrete lower than 35%, and the maximum save water and power resources, can be described as green design, green construction construction. Future, steel buildings can be up to 80% recycled material, and therefore very fit actual needs of all levels of government for the development of recycling economy, low carbon economy and ecological economy.
China's steel construction industry has developed rapidly, especially with the accelerated urbanization and inspire a new round of housing rigid demand for steel residential promotion provides a solid foundation. In recent years, the domestic steel construction companies launch new products emerging. Recently, in the twenty-first real estate fair in Zhejiang Province, Hangxiao showcased the company's newly developed "Steel beam combiner structure housing system." The product is based on modular design, standardization of manufacturing, assembly of construction, information management and customized development to meet reduce labor intensity and reduce construction waste, shorten the construction period, the increased use of the area, seismic mitigation, energy conservation and other buildings industrial modernization and industrialization of new construction requirements. In addition, the Great Steel has launched a special light steel villa product that can be used to build houses for all members of beams, walls, floors, etc.
Meanwhile, steel residential real estate has become some of the competing propaganda "selling point." Tianjin, a listing on promotional materials, "pure steel building nine earthquake, can withstand 70 m / s, super 17 hurricane" is written in the home of the most eye-catching position.
Industry insiders said the green steel building system will break the real estate, construction, machinery and equipment manufacturing, green building, new building materials, disaster prevention and mitigation, kitchen appliances and decoration boundaries between industries, set to become a new type of building industrial cycle industrial system; also the real estate funds flowed back into the real economy in modern manufacturing to achieve economic transformation upgrade. However, the output is not new green economy, government policy support, enterprise innovation and people together are essential elements.
