Steel construction end "fast food room"

The eighties and nineties, around the speed of urbanization, a large number of buildings constructed intensive. They stand in the face of residential buildings, some experts expressed concern that "the spot" urban construction would spawn a lot of good and bad buildings that will one day enter the "Quality revenge cycle."
 
Such concerns unfortunate reality. November 15, 6th floor houses a building under construction in Guangzhou Baiyun District of collapse. The first half of Zhejiang Fenghua only a 20-year-old residential building collapsed, these two incidents are caused no casualties, "snack room" thus brought to the cusp of public opinion.
 
"Snack room" collapse accident-prone
 
In recent years, "snack room" collapse accidents frequently occur: in August 2009, Shijiazhuang two-story building built in the 80s of the last century in the rain collapsed, 17 people were killed; 2011, Nangang District, Harbin, a six-layer the collapse of the residential side of the occurrence; December 2012, delivered more than 20 years, Koto-ku, Xu Rong Mimura Ningbo two buildings collapsed; May 2013, Fuzhou a building built in the 70s of the last century building collapsed ......
 
According to China "civil Design Principles" provisions of the general construction of durable life of 50 years to 100 years. However, in reality, a lot of the requirements and design of the building's actual life General has a considerable distance. An official of the Ministry of Housing has publicly said:. "Our country is the largest country in the new annual construction volume, but the average life expectancy was only last building for 25 years to 30 years." In comparison, the average life expectancy of UK construction reaches 132 in the United States is 74 years.
 
In this regard, the Deputy Secretary-General Chen Xuwei Hangzhou Institute of Civil Engineering, admits: "After the reforms, to solve the problem of people living in many places really built a number of fast-food-style house."
 
Analysts believe that the past 20 years "behind extensive" building construction model, coupled with innate "immunity," a low concrete structures, creating today's "fast food room."
 
"Snack room" or a history
 
"Snack room" a serious threat to the public safety, to abandon the backward traditional concrete construction mode is imminent.
 
In other countries, large-scale use of steel buildings to replace concrete building, or the use of steel technology "dilapidated old houses and shanty towns" do upgrade, not only can reduce casualties during the earthquake, but also to overcome the road from the fundamental "micro shock ', reducing the chance of collapse.
 
Vice president Hsiao Zhejiang Hangzhou Steel Co., Ltd. Sui in the "China Trade News" reporter, said steel structure of the building itself is very stable and have unity, can effectively reduce the road "micro vibration" little impact on the building. At the same time, experience and current practice Hangxiao international experience point of view, life in general steel buildings can reach 80 years to 100 years.
 
However, the community prevalence of steel building "construction cost is high, the price of an expensive building," the misunderstanding, and the immaturity of China's steel and technology, resulting in steel construction in the past has not been a strong popularity.
 
Data show that in developed countries the proportion of steel construction generally above 50%, while China is only 10%. Among them, to ensure the safety of residents living below the proportion of steel housing.
 
"Currently, the state of new urbanization accelerated, the State Department" green building action plan "to be further implemented, some local governments have introduced to steel as the representative for the purchase of green building incentives for tax refund. This not only helps ordinary people out of the steel construction of 'misunderstanding', but also to allow more companies to participate in the popularization of steel as the representative of green building in the past. "Sui said Hangxiao latest development of" a combination of structural steel beams residential system "has been successfully applied for a patent for popularizing steel construction provides a" technology engines. "
 
Hangxiao single silver wood chairman believes that life safety is the first criteria of the building. Hang Xiao use their technical superiority, the end of the domestic "snack room" history as soon as possible, so that people live in a healthy environment, safe safe house.
 
Investigated the regulatory underpinning for safety
 
Building quality and longevity of life is related to the event. For the last century, housing construction in the 1980s and 1990s, the quality problem, of course, is the shortage of technical and financial reasons, "snack room" form, of course, was the factor, but it does not completely clear up doubts.
 
Looking back at the history of China, the arch bridge dating back nearly 1,500 years, still did not fall; even in private, centuries old houses abound. That's no reinforced concrete buildings do not fall main reasons is that there is strict Gou of accountability.
 
Chinese ancient system of accountability is called "Le Gong Ming." That is, after a project is completed or a piece of the product, the name should be printed artisans or supervision officer on the workpiece, which is to take his life in construction engineering quality guarantee and regulators, or that their reputation and the quality of his life and works closely tied together.
 
In 2012, Hong Kong was mandatory building inspection scheme, private owners and the government to clearly define responsibilities: not the absence of government oversight, the owners of buildings as a property owner must take care of the building and repair of responsibility. Industry experts suggest that the implementation of the mandatory building inspection Mainland of China also imperative, localities should soon introduced for local MBIS.
 
Buildings are durable consumer goods, even then a short life span, usually have the use of more than two decades of. Once collapsed, because two decades of time has elapsed, it is difficult to find those responsible. Therefore, the implementation of mandatory building inspection scheme is conducive to advance plans for early detection of problems, accountability, to avoid disputes.
