Value of residential steel

Time:[2014-4-28]  Hits:5594

Since March 2011 , earthquake again and again . In a worry and anxiety , the steel housing , " surface" , became a topic of social concern . In fact, the steel housing is not new , as early as the 1960s , Europe , America, Japan and other countries ( regions ) that began to promote , in China there are some instances , but in the current situation , the people on the steel housing awareness is not high.
    Damping
    Earthquake in Japan , the tsunami make the world panic , Dehong Dai -Jingpo Autonomous Prefecture of Yingjiang earthquake affects people of Burma earthquake followed. Let earthquake highlights the value of steel housing .
    Compare 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 tens of thousands of people have been confirmed killed ; June 18, 2011 , a magnitude 9 earthquake , Japan tsunami dead and missing nearly 3 million people. One wonders : the number of deaths in China, Japan caused by the earthquake Why difference so poor ? Leaving aside the objective factors such as population density , the construction industry believe that the number of casualties is also one of the factors in different residential structures disparity gap .
    Data show that since 1900 , the number of China's earthquake killed up to 55 million, accounting for 53% of global deaths in earthquakes, which houses the structure and material issues are important factors directly causing casualties .
    Japan is an earthquake-prone zone , therefore , extremely high penetration of steel housing , public buildings seismic capacity reaches 10 schools , ordinary residential buildings can withstand earthquakes above 7 . Practice has proved that the Japanese steel buildings caused by the earthquake damage mitigation played a very important role. Steel construction , light weight, its excellent shock resistance is widely recognized around the world .
    Some experts pointed out that the earthquake triggered a tsunami in the Indian Ocean began in 2004 , re-entering the Earth's seismic activity . In 2010 alone , the world will record up to 28 times seven earthquakes . According to seismic activity continued for more than 10 years of rule, in recent years, the Earth is still in an earthquake -prone period . Earthquake Disaster Mitigation urgent work to do .
    In our existing residential , steel accounted for less than 1% , the concept of public steel housing is still very vague. Look at these earthquake lessons learned , to change the traditional way of residential construction , promote steel housing , improve earthquake disaster mitigation capabilities, to protect people 's lives and property , becoming a major problem for the whole community must confront together .
    Needless to say, the promotion of steel housing is a sanctuary of life and respect .
    Decompression
    Over the years, mainly in the field of residential construction manual wet work , the presence of low productivity, long construction period , high energy consumption , serious pollution, difficult to guarantee quality and performance , short life cycle and other issues. The data show that the number of construction waste accounts for nearly forty percent of the total municipal solid waste . According to the brick structure , reinforced concrete structure construction material loss to rough statistics, China's urban construction waste generated each year up to 400 million tons .
    Reduce the production of steel residential brick, lime, cement and gravel excavation and other damage to the environment of traditional building materials , construction waste , construction dust and noise are greatly reduced, alteration and demolition easier , and re- utilization of recycled materials high, many countries see it as an important way of steel reserve .
    Residential construction is resource consumption and greenhouse gas emitters , accounting for about 40% of the total social energy consumption. According to professional research organization , reinforced concrete structure housing material was 740.6 kilograms of carbon emissions / m , while the carbon emissions from steel housing material is 480 kg / m , reduced by about 35%.
    China's population and more livable less land , high urban population density. Thus , the inevitable high-rise residential , multi- high-rise , which is steel housing "high, large , light ," a unique advantage.
    Reduce water consumption per unit of industrial added value , reduce energy consumption per unit of GDP , reducing carbon dioxide emissions per unit of GDP , reducing the amount of arable land occupation and reduce emissions of major pollutants , steel housing with "five " plan binding targets five closely related environmental and resource .
Make it more energy-saving and environmental protection , steel housing worth highlighting .
