Hangzhou has a country's largest steel affordable housing

Hangzhou City Housing Construction Bureau, there had been such an interesting thing: the bureau received a report, said the Hebei Road and Qingchun Road intersection, but not concrete mixer on a construction site Ruifeng International Business Building, overnight actually cover a four floors. Whistleblowers, said: "This is certainly the illegal construction!" Hainan Steel

This is certainly not illegal construction, but the ongoing steel construction, the building also for the domestic high-rise, high-rise steel construction industry has set a technical benchmark. Subsequent years, steel was used in the construction of various landmark. Not long ago, when Li Jiabao chaired a State Council executive meeting held proposed to carry out a pilot steel construction, expand the use of green building materials and the like. Right now, the country's largest steel green area of ​​affordable housing - Qianjiang Century City Talent special space will be completed soon. Yesterday, the high-spirited, he said: years in the change, the construction industry is also change, green house's steel has arrived.

With "Chopsticks"

Same building as building blocks

What is green building? Here it is summarized as follows: in the construction of a full life cycles, the maximum limit to conserve resources, protect the environment and reduce pollution, as people fed healthy, appropriate and efficient use of space. "Simply put, it is to eventually achieve the blue sky back, back to the green earth, clear back to the river."

Soon to be completed Qianjiang Century City talent special space, the construction area of ​​about 660,000 square meters, it is by far the country's largest steel green affordable housing. Recently, the reporter went to the site. Moment into the construction site, they overturned my understanding of the construction industry: here faceless concrete mixing workers, not the roar of machine noise, surrounded by blocks of buildings has not been capped, we can clearly see the all-steel load-bearing wall. More surprising it is that wearing shoes walk around the site, contaminated with a little dust on shoes Jingmei.

"In addition to the construction materials 80% of steel, 60% of construction trash less, prefabricated construction site can also be reduced by 80% of the noise, dust, sewage." Introduction, if you want to come up with a template for a future system of steel structure housing, money Jiang Century City talent special space project should be to break the existing residential systems.

And this break from Hangxiao third generation "steel beam" technology. "Brief, it made so the house is similar to building blocks, and these 'building blocks' are used like 'chopsticks' same 'steel beams' assembled." Building 11, pointed to the construction site, said the 32-storey The construction took only 60 days to end the top of the.

It is understood that the world's leading, "steel beam" construction system has been patented in over 110 countries worldwide. Hainan Steel

Steel construction

The maximum limit can reduce construction garbage

Construction time is short because it constitutes the choice of steel wall, the wall not only with the construction of a feature request sensitive arrangement, but also give full play to the high degree of industrialization and steel production, construction speed characteristics, to meet the reduced labor intensity, shorten the construction period , increase the use of area, energy conservation and other requests.

"Let's first production 'steel beams', and then tailor the project, we want it to be assembled into the 'building blocks'. This way, we can improve the construction speed doubles, saving two-thirds of the human input. "Said, theoretically speaking, the earthquake can not make steel construction collapsed.

In addition to facilitating sensitive when used short, this technology better place, or it is possible to reduce the maximum limit to build garbage.

Our country is the greatest country in the world last year the amount of new construction at present, the annual two billion square meters of new area consumes 40 percent of the world's cement and steel, but also produce up to 400 million tons of construction waste. 400 million tons is the concept? Able to fill 11 West, heap 11 Diaoyu Islands.

"Most of the construction of the city's garbage is shipped to only a very small part of the consumptive designated place, environmental pollution generated more junk should not be underestimated." Said, according to statistics, more than 80 percent of construction waste composition of waste concrete, waste brick waste mortar and other construction material, because of its non-degradable, and can not be landfilled where use as a foundation. More worrying is that many of the construction garbage removal and stacking process caused serious environmental pollution, most of the construction of open dumps or landfill garbage chosen manner, because it is rich in heavy metals, harmful radioactive substances can severely erode the surface, surface water pollution.

More common future construction

Also "Steel"

Speaking of steel construction, perhaps many people will think of Beijing's Olympic Stadium "Bird's Nest", "Water Cube", which applied to ordinary residence in very rare. "But the future, we need the construction industry must be green, healthy and sustainable." He said.

As a member of the CPPCC Hangzhou, almost every year to submit the proposal to the Government to promote steel construction in Hangzhou, the proposal eventually highly Hangzhou government. 2013, Hangzhou introduced the "13 key industry innovation and development of steel and other three-year action plan," the steel inclusion and equal status of e-commerce and focus on the development of new energy industries. Newspaper last year, "Recommendations on to seize the opportunity to create the national housing industry modernization demonstrates the city's" Hangzhou Municipal Government has also been approved: Next, Hangzhou will continue to vigorously promote the construction of new industrialization demonstration base, Hangzhou subsequent Viaduct Construction also has perhaps inclined to steel.

"Cabbage price" steel prices, is also an important factor pushed steel housing industry. "At present, China's steel production accounted for 45.5% of world steel production, first in the world for 18 consecutive years, if the steel used in the construction industry, the plight of countries to decide steel overcapacity." Said the steel industry is not only a modern "Food" or of a national long-term strategic reserve industry, for the benefit of future generations.

Achieve private custom

So that every household can not the same

"Now the private custom prevailed, steel housing can be achieved is not the same in every household." Said, because the construction of four load-bearing steel structure, floor and roof are made of detachable or welded Jharkhand prefabricated containers, In addition to load-bearing walls, other walls can be comfortable open space free combination of natural reality.

"Compared to traditional concrete structure steel structure housing, because the outstanding load-bearing capacity, each 10,000 square meters capable of more use area of ​​500 square meters, with a total residential room rate can be increased by about 5%." Introduction, interior and exterior Prefabricated selected CCA board grout wall, 100% free of asbestos, formaldehyde and other harmful substances, with lightweight, high strength, waterproof, fireproof, thermal insulation of technical advantages.

"Take back the construction industry, the land back to agriculture, the earth back to future generations." In the eyes of steel green building systems in line with the request of green, low carbon, environmental protection, energy, conservation, recycling and sustainable development , the traditional construction industry into the field of industrial modernization, so that green building into the new era.
