Since March 2011 , earthquake again and again . In an anxious and restless , the steel layout residence "surfaced " into the social importance of the topic . In fact , not new steel shelter layout , back in the 1960s , Europe , America, Japan and other countries ( regions ) that is beginning to implement , in China there are some instances , but it is on the current status of everyone on the steel layout residence awareness is not high.
Damping
Earthquake in Japan attacks , the international tsunami panic , Dehong Dai and Jingpo Autonomous Prefecture Yingjiang earthquake touched people , one after another earthquake in Myanmar . Let earthquake disaster highlights the value of steel layout residence .
Compared to China Wenchuan "5 • 12" earthquake with "3 • 11" Japan earthquake, a group of shocking data before -
At 12:00 on August 11, 2008 , magnitude 8 earthquake in Wenchuan has acknowledged tens of thousands of people were killed ; June 18, 2011 , a magnitude 9 earthquake , Japan tsunami death and missing nearly 3 million people. We can not help asking : Number of death in China, Japan formed by the earthquake difference so why the disparity ? Down raw objective elements such as population density , the construction sector that one is also not the same as the number of casualties from the poor house layout elements .
Data show that since 1900 , the number of Chinese earthquake killed up to 550,000 , accounting for 53 % of the global number of earthquake death during house layout and data queries are an important element of direct casualties formation.
Japan is an earthquake-prone zone , and thus , a high penetration of steel layout residence , public construction in seismic campus to reach 10 , the general population shelter can withstand earthquakes above 7 . Practice has proved that the Japanese steel construction layout earthquake damage mitigation formation plays a very important effect. Light weight steel construction layout , its excellent shock in order to be widely recognized international countries .
Professor pointed out that the earthquake triggered the 2004 Indian Ocean tsunami beginning to re-enter the Earth's seismic active period . Only in 2010 , the world will record up to 28 times seven earthquakes . More than 10 years in accordance with the rules of the earthquake continued lively period in recent years, the Earth is still in an earthquake -prone period . Earthquake Disaster Mitigation good job imminent.
Existing dwellings in China , the share of steel layout lacks one percent , the concept of public accommodation layout steel still vague. Examine the experience of these years earthquake , altered the traditional method of creating shelter , promoting steel layout shelter, disaster reduction progress to protect people 's lives and property , it becomes necessary to confront together the whole community of serious doubt .
Needless to say , the implementation of the steel layout residence is the protection of life and respect .
Decompression
For years, Chinese premier choice of residence construction site craft wet work , there is a production of low power, long construction period, high energy consumption, serious pollution , difficult to ensure the quality and functionality , life cycles and short questions . The data show that China accounted for nearly forty percent of the total amount of waste construction of municipal waste . Loss of roughly based on the layout of brick and concrete , reinforced concrete and other construction layout construction materials, construction waste annually China's township occurred up to 4 million tons.
Steel layout shelter materials to reduce the damage produced brick, lime , cement and gravel excavation and other traditional environmental , construction waste , building construction dust and noise are greatly reduced simple alterations and demolition , recovery and re- utilization of information high , an important method of steel in many developed countries see it as storage .
Home construction is a resource -consuming and greenhouse gas emitters , accounting for about 40% of the total social energy consumption. According to professional organizations, seminars, reinforced concrete layout residence was 740.6 kilograms of carbon emissions data / square meter , steel and carbon emissions data layout residence is 480 kg / m , a decrease of about 35%.
China tooth much less livable land , high urban population density . Thus , high-rise residence must , more than high-rise , which is steel layout residence "high, large , light ," the common advantage.
Decreased water consumption per unit of industrial added value , unit of gross domestic product decreased energy consumption , unit of gross domestic product decreased carbon dioxide emissions , reducing plowing footprint , reducing the primary pollutant emissions , steel layout residence and "Twelfth Five Year Plan" environment and bondage sex in five closely related resource policy .
Make energy-saving and environmental protection become more real , steel layout highlights the value of homes .
Lightening
"Twelve Five" period will build 36 million units to ensure the room, facing the certainty increment, in addition to crack the problem of land and capital , accelerate the construction speed , ensuring both speed and quality, the same is a serious challenge .
Residence industrialization is a shortcut. Residence residence industrialization industrialization carried out depending on the extent and level of industrialization of parts . In these respects, steel layout residence is now scrambling .
Back in 2002 , the Tianjin Construction Engineering Group to develop steel - concrete composite layout, Laiwu Steel, Maanshan Steel, Benxi Steel and other domestic steel companies also continue to develop a variety of new steel to steel supply powerful professional layout support.
2009 , depicted by the independent Hangxiao , the first domestic steel distribution group home devices - Wuhan century home was completed. With a "building block " approach to build a house has now become reality.
October 1, 2010 , residential and urban and rural construction department issued a " lightweight steel layout skills residence rules " official purposes , as depicted in Chinese light steel shelter layout , construction and inspection of the specification and in accordance with supply . China Light Steel layout residence from a legal basis .
December 7, 2010 , "State residence industrialization base" in Hangxiao listing, which is determined by the Ministry of urban-rural residence and construction layout of residence issued by the national steel industrial base, industrial layout has steel shelter Speaking agenda.
Chinese steel output is now among the international top successive years . After several years of launch , the domestic steel layout residence industrialization increasingly sophisticated skills , laying a solid foundation for the industrialization of China home .
Steel layout residence is completed residence industrialization breakthrough, is the completion of the "five " Housing construction techniques to ensure a strong policy ; steel layout and production house will make the day even more matches to complete the real energy saving ; steel shelter so that the upstream and downstream linkage layout , will the femoral artery and steel, machinery manufacturing, industrial depicted , data recovery and a series of industrial chain of promotion and conduct .
Home layout further highlights the value of steel .
Attrition
Changes in the real estate profession of traditional , low-end to carry out the method to promote labor-intensive to knowledge and skill-intensive career change , reducing excessive labor and resources to rely on, steel layout residence is the inevitable choice of industrial promotion .
A steel layout built on inquiry revealed that traditional steel-concrete layout of the residence because some cast many , many workers live hand job demand industry , steel parts layout residence is completed , industrialization , labor can cut 2 /3.
Steel production layout residence will greatly liberating force , such a huge attrition will help build migrant workers to other professional activities .
If the government classified these migrant workers serve the public system , consistent with the principle of consistent management, consistent serve , strength training , completed vocational gradient moving, inspiring many areas of real estate knowledge and skills to carry out labor -intensive industries direction , so that they become a social worker to ensure that the industry not only helps the progress of the remuneration packages of migrant workers , and help alleviate the "labor shortage ." Value of Steel layout residence increasingly prominent.
