The state encourages the developmentSteel structure housing
Steel structure housingIs our country residence development direction. Steel structure building in China accounts for the proportion of domestic architecture is very low, less than 5%, while developed countries are more than 50%. Steel structure housing compared with the traditional structure of brick and concrete structure house, it's very light weight, energy consumption is also very low. If the steel structure of energy consumption and carbon emissions is 1, the concrete structure is about 1.4, and 60% of steel structure building after the demolition materials can be recycled.
Emphasize the overall residential concept. Semifinished product of energy consumption, especially the construction waste, co2 emissions impact is very big. According to the 2009 national residential quantity measure, carbon emissions reached 7.7 million tons. So, we emphasize should attach great importance to the whole of residential decoration, whole room is listed.
Steel structure building has a benefit, it is only when the house demolition less manpower and material resources, steel can be recycled. And use the large amount of cement concrete building, demolition, recycling is difficult. Japan and some European countries, even to reserve resources of iron and steel in construction. As a result, a large number of steel structure residence is also social storage steel the strategic resources of the effective ways.
Urban development and environment research institute Chinese academy of social sciences, said pan & other; Before the country has established five province 8 pilot city low carbon city, a lot of places all want to have pilot 'hat & rsquo; . The pilot and the nature of special economic zones, national preferential policies for pilot areas have not, now is an open economy, it is impossible to special treated differently. Low carbon economy should be the whole society, all the so-called targeted pilot is these places to do more. We must recognize that low carbon is a process, not step in place. In the long run, we must to go to this direction, but also to accelerate low carbon transformation, but now in some places the so-called zero carbon slogan, can say it is a sign of ignorance. Throughout the &;
& other; In construction, whether existing residential or new housing, housing total is far greater than the total amount of public use, housing is very important to the whole society of energy saving. We advocate in residential construction, the window wall area ratio should be decreased. Now many window outside his home area is too large, such as the big bay window, bay window, the energy saving is very adverse. Pioneered the use of external shading systems, renewable energy, especially solar building integration. To minimize the landscape water body design. Reduce residential building has no function of architecture and decoration, such as decorative wave plate, roof do it without any functional meaning, not only the cost is high, and very bad for the earthquake. Throughout the &; Commissioner of ministry of housing industrialization promotion center performance that LouNaiLin said.
Steel structure products follow the era demand
Construction of industrial transfer and mass transport facilities the explosive growth of demand for steel products has been the fact that does not dispute. Compared with traditional building materials and engineering materials, steel structure product has some specific advantages and make them under the time background of low carbon environmental protection have more comparative advantage.
First of all, all steel structure steel structure can be recycled, is recycled's new tallest building products. Second, the production is simple, generally in the specialized factory manufacture, can batch mass production, high degree of industrialization. Steel truss structure adopts the construction mode, more than 1 times quicker than the traditional construction method, construction period is short. And, more importantly, the ductility of steel structure is good, strong tensile, aseismic capacity than other building, is the strongest construction safety performance. The earthquake that struck the performance at home and abroad, has been fully validated.
Compared with the developed countries, our country's steel usage is still very low. 2008, the steel output of 21.8 million tons, accounting for 4.38% of the crude steel production. Steel structure in developed countries accounts for the proportion of crude steel output in more than 10%. British steel structure in the residence of multi-storey building market share increased from 33% in 1980 to 70% of the early 21st century; In single layer of residence building, steel structure occupies 98% market share.
Application domain block in the largest residential areas, the steel structure housing the main reason for the low penetration and poor residents' acceptance for this type of housing, the cost is not the main reason. At the same time,Steel structure fire protectionower, sound insulation effect of defects directly affects the user's utility, and its advantages compared with the user's relevance and utility. This leads to steel structure residential market share is small. But, the fire and sound insulation problems can be solved, as long as use metope material sound insulation problems can be solved. Fire protection problems through the use of new steel material (different alloy), coating, the steel structure can solve. If these two problems can be resolved on the premise of cost does not increase, so the steel structure housing market can be expected.
