Guangzhou steel structure: development of steel structure building dissolve excess capacity
Guangzhou steel structure: steel structure of the expert committee of China construction metal structure association annual work conference in han, more than 200 experts, business representatives gathered in caidian steel structure. Three Chinese academy of engineering, professor of tongji university zu-yan shen, zhejiang university professor dong shi-lin, guizhou university professor Ma Kejian common advice, to develop the steel structure building, to resolve the severe excess steel production capacity.
Zu-yan shen with "light, fast, good, province" to describe characteristics of steel structure, he thought, steel structure buildings is most suitable for industrialized production. Dong shi-lin brings his latest research results, a composed of six pole tetrahedron unit "spherical reticulated shell", is advantageous for the industrialization precast production. Ma Kejian, site promotion multilayer long-span grid structure, mainly used in prefabricated construction.
According to introducing, eighty percent steel structure building components can be processed in the factory, at the same time easy to dismantle, part of the product and repeatable, recycling materials, is an important representative of the green building. Compared with the traditional concrete building, its weight reduce 40%, 4 times higher construction efficiency, shorten the construction cycle, one third of carbon emissions by 35%, the rate that get a house increased by more than 5%, in the developed world is widespread.
Statistics show that in recent five years, China's steel weight of the steel structure building in 30 million tons to 50 million tons, steel production accounted for about 5%, 45% 45% compared with the United States, Japan, Germany, compared to 22% obviously on the low side. Academicians think: by promoting, the development of steel structure building, can dissolve the iron and steel industry overcapacity, also can promote the industrialized construction, realize the transformation and upgrading of traditional industries.
