The four values ​​of the steel structure housing

Since March 2011, the earthquake again and again. A worry and anxiety, steel residential "surface", has become the topic of social concern. In fact, the steel structure house is not new, as early as the 1960s, Europe, USA, Japan and other countries (regions) that began to promote, there are some instances in our country, but the present situation, the steel structure residential awareness is not high.
Damping
Japan earthquake, tsunami make the world a panic, Dehong Dai and Jingpo Autonomous Prefecture in the Yingjiang the earthquake affect people, the Myanmar earthquake followed. The earthquake disaster highlights the value of steel residential.
China Wenchuan, "5.12" earthquake "3.11" earthquake in Japan, a group of alarming data that lies ahead -
August 11, 2008, magnitude 8 earthquake in Wenchuan, Sichuan Province, has confirmed that tens of thousands of people were killed; June 18, 2011, Japan Richter 9 earthquake and tsunami dead and missing nearly 30,000 people. People will ask: China, Japan, the number of deaths caused by the earthquake Why such a disparity difference? Leaving aside the objective factors such as population density, the construction industry believe that the different residential structure is also the number of gap one of the factors casualties.
The data show that since 1900, the number of people died in the earthquake in China up to 550,000, accounting for 53% of the global earthquake death toll, which the housing structure and materials is an important factor in causing casualties.
Japan is earthquake-prone zone, therefore, the penetration rate of steel residential high school in public buildings seismic capacity of up to 10 ordinary residential buildings can withstand earthquakes above seven. Practice has proved that the Japanese steel construction and light building material has played a very important role in the mitigation of damage caused by the earthquake. Steel construction, light weight, excellent seismic capacity has been widely recognized around the world.
There is no doubt that the promotion of steel structure housing the asylum and respect for life.
Decompression
Over the years, our residential construction field manual wet work, there is low productivity, long construction period, high energy consumption, serious pollution, is difficult to guarantee quality and performance, short life cycle and other issues. The data show that the number of construction waste in China accounted for the nearly forty percent of the total municipal solid waste. According to rough statistics of the loss on the construction materials of brick and concrete structure, reinforced concrete structure, the annual China's urban construction waste generated by up to 400 million tons.
Steel structure housing to reduce the environmental destruction of the traditional building materials of brick production, lime, cement and excavation of sand and gravel, construction waste, construction dust, noise is greatly reduced, easy alterations and demolition, materials recycling and re-utilization , many developed countries see it as an important way of reserves steel.
China's population and more livable land is limited and high urban population density. Therefore, housing must mainly to high-level, multi-high-rise which is the steel structure residential "high, large, light the unique advantages.
Reduce the water consumption of unit of industrial added value, reduce the per unit GDP energy consumption, reduce the per unit GDP carbon dioxide emissions, reduce the amount of arable land occupation, and to reduce emissions of major pollutants in the steel structure house with the "12th Five-Year Plan binding targets for five of the environment and resources is closely related.
More substantial energy-saving and environmental protection, and highlights the value of steel structure house.
Reducing the burden
The housing industry is a shortcut. The development of the housing industry depends on the extent and level of domestic industrialization of parts industry. In these respects, the steel structure house has been pre-empted.
As early as 2002, the Tianjin Construction Engineering Group to develop steel - concrete composite structure, Laiwu Steel, Ma On Shan steel plant, Benxi Steel and other domestic steel companies constantly develop new types of steel to provide strong support for the steel industry.
2009 by Hangxiao Steel independently designed, installed the first steel housing complex - the completion of the century home in Wuhan. "Building blocks" to build a house has become a reality.
December 7, 2010, the national housing industry base in Hangxiao Steel listed, which is granted by the Ministry of Housing and Urban national steel housing industry base, the steel structure of the housing industry has been referred to the important agenda.
China's steel production has been for many years ranked first in the world. After several years of development, the domestic steel residential industrialized technology is maturing, and laid a solid foundation for the housing industry. Steel structure housing the upstream and downstream linkage, will lead the iron and steel, machinery manufacturing, the industrial design,stone coated metal roofing tiles manufactury, material recovery, upgrading and development of a series of industrial chain.
Further highlights the value of steel residential.
Attrition
Change the real estate industry, the low-end development, promote the transformation of labor-intensive industries to knowledge-and technology-intensive, to reduce excessive dependence on labor and resources, steel residential industrial upgrading.
The survey shows that a steel structure building, traditional reinforced concrete structure housing situ part of many, the need for manual operation of a large number of workers in the scene, steel residential realized the parts, industrialization, and can reduce labor 2/3.
The steel structure house will greatly liberating the productive forces to such a large downsizing will help the flow by the construction of migrant workers to other industries.

how to find their own housing problems
"Global China": or to talk about the reader care about the problem, I ask people how the roof?
Liang Ganghua: Customers are not professionals, only about one is to look at the chimney straight not straight, if not straight, indicating that there may be housing based. Depends on the roof level uneven, that horizontal line on the roof from the outside, if uneven foundation or structure.
"Global Chinese Press: the type of roof, in general, what kind of roof is better?
Liang Ganghua: Use the longest on the cement tiles, generally over several decades, the tile is the most durable, but at high cost. The stone coated  metal roof is durable, but not insulating, industrial, civil relatively small. Asphalt life as tiles, asphalt replacement costs are lower. There is also a timber roof, the drawback is the small raccoons have the opportunity to dig a hole to crawl into to do nest from the wooden roof. Generally speaking, in the case of the same material, the higher the slope of the roof, the longer the use of the roof. But depends on the design of the roof. Look to replace a roof, depends on the status of the roof material, but also from inside the house to see, to verify.
"Global Chinese Press": from the house to see how?
The Liang Ganghua: from the top of the triangle inside the house, the insulating layer to see. If the roof water seepage, you can see from the triangle top. From the top of the triangle can also see across the house warm cotton enough. Can also see the wire and safe to the above, the arrangement of the vent is not correct, find no traces of small animals.
"Global Chinese Press": If you look at the yard to see how?
Liang Ganghua: branches, and the house can not rely too close, too close to trim, otherwise it will affect roof life, the foundation will also be affected. So looking for an apartment, try not to look for a tree next to the house, so animals are also easy to jump to the roof along the branches. Lawn check does not include the automatic sprinkler system, and the sight of the ground does not include.
"Global Chinese Press": living room, pay attention to what issues?
Liang Ganghua: fireplace to check the fireplace, gas fireplace to check the drain does not leak, combustion of carbon monoxide release. If it is a wood fireplace to check the wall cracks, to prevent the leakage of carbon monoxide. If the electric fireplace is generally no problem.
"Global Chinese Press: The bedroom should pay attention to the problem?
Liang Ganghua: First of all depends on heating it enough, unsafe electrical safety performance of windows. In general, the plastic window is more environmentally friendly. If the room is inside the suite bath also check together.
"Global Chinese Press": what to pay attention to the kitchen?
Liang Ganghua: depends on vegetables basin leaks, look at the dishwasher there is no leakage. General obligations of household appliances to see whether it can use, but does not include the inspection items, because the life of electrical appliances is difficult to judge, it is difficult to predict, at any time may be damaged.
"Global Chinese": bathroom to pay attention to?
Liang Ganghua: To check that there are not enough exhaust. Government regulations bathroom or have a exhaust fan, or have the windows open. To check for leakage, leakage, general bathroom to be fitted with leak-proof electric power outlet. Also check all the faucets, the use of performance of the toilet, sink below the absence of seepage and mildew, and other, and so on.
"Global Chinese Press": basement to pay attention to what?
Liang Ganghua: depends on the wall there is no water seepage, foundation humidity not too high. If the wall has a watermark, there may be outside of the drainage system. Heating system and boiler in the basement to check the ventilation system to ensure that the basement fresh air flow. Also check the heating system and boiler working conditions, to see if the residual gas leaks, carbon monoxide. You can also check the wind warm compartment cotton or need replacement or need to do the cleaning and maintenance. Water heater life expectancy of 10-15 years, we will determine the life, how long it takes to replace.
"Global Chinese Press": external wall have to check it?
Liang Ganghua: Yes. In Canada, the external wall material is cement, wood, fire plastic three, bricks, stones are relatively small. Mainly to see that there is no normal wear and tear, normal cracks, in order to reduce the chance of water seepage. Cement walls of hair the size of the cracks do not need to worry too much about, because there are thermal expansion and contraction. Wood and cement walls do regular paint maintenance. To avoid gardening too close to the external walls, resulting in damage to the external walls. Gardening soil contact with the external walls of the material, only to the height of the base cement.
"Global Chinese Press": what to pay attention to?
Liang Ganghua: circuit inspection, first look at the master switch should switch panel is open to determine the installation of the inside of the line together substandard, the wire material is copper, there is no leakage protection switch. Inspection items balcony, garage. To check the garage door, switch security, an obstacle will automatically stop the decline. After completion of all projects to check, I will be the scene on the computer, print the home inspection report to facilitate the preservation and burn on the CD above. After completion of the report, I need to do on-site explanations to help them accurately understand the quality of housing conditions.
"Global China": the readers to understand these can be your own home inspection?
Liang Ganghua: If you will not need the housing inspection division to learn more than a year to do this work. These are just a rough, readers can about the situation to do a rough observation and found the problem immediately to find a professional home inspection division to see. Housing inspection division for a checkup just check in the broad sense, encountered a more prominent or more professional or looking for experts to do further checks. For example, a gas leak, to find a gas company to further examination. If foundation problems, looking for construction engineers to further determine. However, the housing inspection division of the range of services, our general detached charges is 400-600. If you find a professional heating company to check heating, about 200, to find the professional inspection company to do a roof 200, the above two projects on the 400, the housing inspection division of the checks, After looking at at least 10
