China's rapid rise of steel structure housing

"In addition to super high-rise buildings, large factories, and public buildings, my country also has a lot of room for promotion in steel structure housing." However, "in recent years, the prices of raw materials have increased frequently and the increase is too large, which has severely impacted the overall efficiency of the industry and led to enterprises. Lilube Slope has seriously affected the healthy development of this new industry in the future."

At the “China Iron and Steel Market Situation Analysis Seminar” held not long ago, Li Xinchuang, one of the participants in the 2009 China Iron and Steel Industry Revitalization Plan and vice president of the China Metallurgical Industry Planning and Research Institute, said that China’s steel production capacity is currently serious. The surplus, especially the relative surplus of industrial strips, the state should encourage vigorously develop the steel structure residential market and open up the steel market.

　　So, what is the situation of the development of the steel structure construction industry?

"The Ministry of Industry and Information Technology has entrusted us to conduct a thorough investigation of the development of the steel structure industry." Cui Hongwei of the China Steel Structure Association told reporters that the rise and development of steel structures in China has only been more than ten years, and it is a new industry. Want to clarify the specific situation of the development of this industry, in order to specifically consider the development policy of the industry.

　　The rapid rise of steel structure housing

　　 In March this year, the country’s largest steel structure residential demonstration project ─ Wuhan Century Home was completed. Different from ordinary real estate projects, on the day when the Wuhan Century Home Project was completed, the project contractor Hangxiao Steel Structure Co., Ltd. specially hosted a technical exchange meeting, inviting industry experts to comment on the project, and at the same time to discuss the technical issues of steel structure housing .

Steel structure residence

As the earliest enterprise engaged in the production of construction steel structure in China, although it has done countless important construction projects and pioneered the construction of large-scale steel structure factories and high-rise buildings in China, Hangxiao Steel Structure is still very important for the completion of this large-scale steel structure residence. Pay attention. After all, in China, the application of steel structure in public buildings such as super high-rise buildings, large-span factories and stadiums has been very common, but there are not many applications in residential buildings. Really systematically develop and industrialize steel structure residential buildings and realize The only enterprise supporting the industrialization of structures, floors, and walls is Hangxiao Steel Structure. Hangxiao Steel Structure hopes to use this project to show to the real estate industry that steel structure houses actually have incomparable advantages over brick structure houses.

The Wuhan Century Homes project has a construction area of approximately 230,000 square meters and consists of 11 high-rise residential buildings with 22 to 24 floors. The project adopts steel-reinforced truss floor decks independently developed by Hangxiao Steel Structure and has light weight, sound insulation, heat preservation, The CCA interior and exterior wall system with superior performance such as waterproofing and fireproofing can not see the clay bricks in the entire main building. It is the first truly domestically-made green, environmentally friendly, energy-saving, and earthquake-resistant high-rise steel structure residential building project in China.

"The completion of this project means that our multi-high-rise residential steel structure building system has matured." A manager of Hangxiao Steel Structure told reporters that in fact, before undertaking the Wuhan Century Home Project, the company had already set up a steel structure dormitory building for employees in Hangxiao. As well as the promotion and application of its steel structure residential technology system in many projects such as foreign residential projects. Their practice once again proved the advantages of steel structure houses. One is the low cost, which is generally one-third lower than that of concrete buildings of the same scale; the second is the fast construction, and the construction time is two-thirds of the concrete building; the third is the heat insulation. , Good heat preservation and shockproof effect, which can increase the use area rate by 5% to 8%.

　　 It is understood that in foreign countries, the application of steel structures has a long history. As early as 1931, the United States used steel structure technology to build the 102-story New York Empire State Building with a height of 381 meters. However, the rise of steel structure buildings in our country did not last long. It was not until the late 1990s that it was gradually used in public facilities such as super high-rise buildings, industrial plants, and municipal elevated buildings. It only developed rapidly after 2000. “The 24-story Ruifeng International Business Building we built in Hangzhou in 2001 was the first self-designed, self-made and self-installed steel structure high-rise building in the country.” The manager of Hangxiao Steel Structure recalled that at that time, the project It has been included in the science and technology demonstration project promoted by the Ministry of Construction, which has attracted widespread attention.
