Hangzhou City, Zhejiang Province, Xiaoshan reporter first. Chang Jiang Qian Century City professionals of the project site, by Hangzhou piano performance construction tenders construction general contracting construction projects. And the common scene: the scene there are other traditional construction scaffolding also dust flying. Project Manager He Hongwu five Wei reporter project uses the technology of steel structure construction, namely buildings of beam, column and lateral force resisting members all the factory production welding steel pipe concrete or hot-rolled H-section steel and production.
He Hongwu five Wei pointed to the use of the third generation of steel construction technology to build the 11 layer. The building on the ground floor of a total of 32 floors, almost 100 meters, construction area of more than 1 square meters, 60 workers in the 60 days after the construction of the basic upper limit set. If the use of traditional concrete structure, the construction of the main building needs 180 workers about 6 months to complete. Therefore, the use of steel structure technology projects, labor and time are reduced by about 2/3.
Attention to the steel structure of the building, causing their first green building concept. Hangzhou piano performance construction group vice chairman, professor level senior engineer as hung is proposed, including steel structure residential, and other various civil. Architecture compared with the traditional way, steel structure building life cycle, energy saving, land, water, materials, environmental protection, reduce about 40% of the sand, cement with a veritable "green building"; about one third construction steel structure residential emissions of carbon dioxide about per kilogram / square meters, than traditional concrete houses about 740 kilograms / square level low.
Another good. For example, the same construction standards meet as the premise, with reinforced structure of column and beam geometric ordinary concrete to small, thin, small occupied space, steel structure residential more increase 5 ~ 8% of the rooms of indoor speed;
For example, the steel structure is more reasonable, seismic performance; prefabricated assembly of the higher degree of installation speed.
A work like this, the Yangtze River in the city of the Yangtze River has been the construction of steel structure". Hung method put forward. In the past few years, the performance of the piano in Zhejiang Province, Inner Mongolia, Hubei, Fujian, Henan and other places of the project, some of the projects by the local post project. For example, 250 thousand square meters of space for the son of an infinite family of the most mature domestic steel structure residential system is the national "science and technology demonstration project", "National Green Innovation Award"".
"Throughout the life cycle of steel structures throughout the reduction, the characteristics of the resources and the development of the steel industry requirements, invariably. "Single Zhou Jinfa, China Iron and Steel Industry Association, recently published" analysis of the 2015 under half of the steel industry operating characteristics and situation of second half of the year plan is among the two kinds of words: "improve the efficiency of steel products, application promote the iron and steel full life cycle reduction, and green. "
For example, although he did the reinforced concrete member in the reinforced concrete. However, in the process of damaged concrete, not only a large number of dust particles, but also high cost, recycling is also large. Steel structure of the building up to the sub, 90% of the steel recovery rate is high, the recovery is more convenient for each set of." A steel structure".
In our country the earliest national residential industrialization base of steel structure, the Hangzhou piano performances constitutive Hangzhou new building steel structure construction industrialization production base, the reporter saw more than 250000 square meters, factory production order orderly, advanced digital cutting equipment, fully automatic manufacturing industrial technology, industrial robots etc. display. There is a pungent smell of the scene, sometimes only a spark ear machine work. According to reports, production of the steel structure of the main power consumption and the selection in the air, carbon dioxide and inert gas protection welding, derusting and painting seal whole plant almost not absolutely new carbon dioxide emissions of harmful gases.
