The Xinglong Street II Pedestrian Bridge in Zhengzhou City was manufactured by our company and was successfully hoisted in February 2013. The east pedestrian bridge project of Xinglong Street II in Zhengzhou was manufactured by our company and successfully hoisted in February 2013. In January 2013, On the 2nd, the reporter saw the hospital building in Xuzhou Feihong Grid Construction Co., Ltd., the city's first steel structure residential prototype room has completed the roof anti-corrosion project. The ground floor area of 200 square meters, underground more than 100 square meters of basement housing, the main body is completed by steel structure, the room wall is separated by a special wall maintenance system built. According to reports, compared with the traditional brick and concrete residential buildings, the steel structure of residential slightly higher cost, but the same construction area can be used in an area of about 5% more.
Speaking of grid, steel structure, people tend to think more of railway stations, stadiums and other public facilities and commercial buildings, few people think of steel houses. It is understood that, at present, the Ministry of Housing and Urban "light steel structure housing technical regulations" have been released, can use more steel construction, building a large number of safe, reliable, green, suitable for residential Habitat, will become the city and even the steel industry Face the greatest opportunities for development.
Building a house like a building block "Outside the country, purchasing a low-density steel house is like buying a car. The user only needs to pick out his favorite steel structure on the drawing. The factory will load the components of the suite Pull in the container to the construction site, a few workers can put the house within 20 days. "City Federation of Industry and Commerce vice president, Xu Hong Feihong grid construction chairman Gao Hong introduced.
Gao Hong told reporters that the steel structure refers to the use of steel structures to do load-bearing structure, with environmentally friendly, light body, energy-saving materials to do the dwelling house structure. According to the relevant state regulations, there are generally three types of domestic steel structure houses: one is a low-rise residential building (less than 3 stories) with a light-weight steel bearing wall system; the other is a low-rise residential building with a steel frame structure (below 6 stories); Three types of steel frame support, steel frame concrete structure of the cylinder structure and other high-rise residential. Contrary to the on-site construction of concrete structure houses, the components of steel structure houses are generally prefabricated at the factory and then assembled at the construction site, on the same principle as building blocks. First, the steel frame erected, the general structure of steel columns to take a 3-4 layers of a construction section, a hoisting at the scene; correction in place, and then coated with anti-corrosion, fireproof materials, concrete floor is poured; the wall with composite Insulation wall panels.
No matter for developers, builders or buyers, the short construction period of steel residential buildings is very obvious "affordable." Zhong Xianghua, vice chairman of Jiangsu Steel Structure Association and party secretary of Xuzhou Feilong Network Construction Co., Ltd., told reporters that because all the components of the light steel structure are spliced and installed from the factory to the site, the construction speed is very fast, which greatly shortens the development cycle. "For example, a two-story, five-storey, light-weight residential building needs only one month to build and about four to five months to build a brick or block of the same size, Developers can reduce the investment risk caused by changes in market demand, but also early repay bank loans and speed up the turnover of construction funds, which can bring huge economic benefits. "
Steel construction and environmental protection benefits of energy and more
Steel housing residential advantages in environmental protection relished by the industry. Due to its own weight to reduce the steel structure, the basic construction of a small amount of earth, the destruction of the valuable resources of the land is small and significantly reduce the use of concrete and brick. Even if the useful life of the house expires, there is less solid waste generated from the structure dismantling, and the scrap can be recycled 100%. Moreover, the dry construction of steel construction technology, but also conducive to water conservation. It can be said that steel construction has the least impact on the urban environment.
The environmental protection of steel structures is not only reflected in the aspects of saving land and water resources. Zhao Dun, general manager of Xuzhou Feihong Grid Construction Co., Ltd., who once designed and constructed high-rise steel-framed residential buildings in Sichuan, Inner Mongolia, Ningxia and Hainan, said that people most feel "affordable" is the indoor layout Flexible, increase the effective use of the building area. "The steel structure of residential buildings using beam and column system, changing the traditional brick and concrete structure of the wall to load-bearing structure, transparent space, users can design and use of flexible space requirements. Of users, the same construction area, steel structure will have more use of the area, which is also the most attractive place for buyers.
In addition, the price, the high cost of steel residential is a misunderstanding. Zhao Dun said that just looking at the cost of steel housing seems to be higher, but if you count the entire life cycle of the building, steel structure residential energy saving, environmental protection and other benefits, count the basic structural steel materials can be recycled forever The cost of steel houses is not high at all.
The promotion of steel structure housing is of great significance
In fact, there are quite a few successful examples of light steel residential buildings in China, and related manufacturing companies are also emerging one after another. Ministry of Housing and Urban "light steel structure residential technical regulations," the introduction of the light steel structure industry has the official standards and basis for the relevant mechanical and electrical products, chemical products, new building materials products provide a broad space for development.
Zhong Xianhua believes that steel structure residential will bring huge changes to the traditional construction mode of "Qin brick and tile" in China, so it is hailed as the "fourth residential revolution." Huge business opportunities have attracted the attention of many domestic and foreign enterprises. Many domestic steel structure production and processing enterprises are planning some demonstration projects in preparation for the upsurge of steel structure house construction.
Ten years ago, Xuzhou Feihong Construction began to participate in the national seminars on steel structure housing and the formulation of relevant rules, is the industry pioneer. Now it has built a new steel processing base of 50,000 square meters and introduced the advanced production line of Peiting House, possessed the strength of industrialized processing base of national steel structure houses. Moreover, in recent years, more and more foreign projects undertaken by our city grid and steel structure enterprises have won with high quality and fast construction speed. With the vigorous promotion of steel structure residential building in this emerging industry, Xuzhou, which owns more than 10 state-owned steel structure engineering contractors and qualified enterprises, can add another dimension besides "the hometown of grid" National steel structure housing industrialization processing base banner.
Gao Hong, who has been paying attention to the industrialization of steel structure houses, admitted frankly that although Xuzhou already has Feihong Construction Co., Ltd. and Sinoma Group carried out the relevant technical cooperation and basically completed the model room, but the full promotion of light steel structure residential also requires a process , Which not only needs the support of government-related policies, but also needs real estate developers, building materials manufacturers and people to recognize the structure of the building. Therefore, the future of light-weight steel houses depends on many factors. (Reporter: Wang Zhengxi)
