Dayi air rail test line focuses on the new product of air rail test line.

There is a “strongest brain” to help this “super aircraft carrier” of the construction industry ride the wind and waves in China’s MCC (Chengdu) construction science and Technology Industrial Park with a total land area of 550000 square meters To inject a steady stream of intellectual and technical support into the prefabricated concrete production base and prefabricated steel structure production base in the park.

The strongest platform: one belt, one road, is the most important platform for the assembly and construction of our province.

As the main force of capital construction of the national metallurgical construction team and the leader of emerging industries, it has long adhered to the road of high-tech and high-quality development..

Never forget the original heart ， keep the mission in mind, never delay a day, and never slacken.

The center successfully organized and implemented a super large cable steel box girder structure with a main span of 820m across the Yibin Yangtze River, weighing 10650t.

At the moment, “the strongest brain” is fully “activated” to stimulate the majestic power of “cutting through thorns” for the journey of building a first-class SMC! In 2020, issue 125 · 235 content source / MCC 5 meets you here, issue 1129 · 3445 of “beautiful MCC”.

In May 2020, it hosted the inaugural meeting of Sichuan steel structure prefabricated housing industry alliance.

This “strongest brain” is the fabricated construction engineering technology research center of MCC 5.

Chengdu open air music Park Center successfully applied the “construction technology of double curved steel box arch + saddle prestressed cable structure” to the construction of Chengdu open air music Park, the largest dome sky curtain in China.

It has more than 100 patents, such as “turning method of major components” and “mixed drilling method for assembly hole tolerance of steel components”.

Guang’an Zhanqian Avenue public rental housing project is the first fabricated high-rise steel structure residence in our province.

Through technical research, the center has realized the research and application of manufacturing and installation of long-span double spiral fabricated steel box girder bridge, and solved the problems of large welding deformation and uneven structural stress distribution.

Lifting Clutches

Strongest support: relying on the profound advantages of MCC 5 in the field of prefabricated steel structure construction, the domestic first-class prefabricated building technology base takes the core technology of model accurate design, steel structure technology, enclosure wall technology, standardized assembly technology and intelligent component supporting integration system.

Nanxi Yangtze River Bridge, known as the “first span in Sichuan”, is 1.424km long.

On January 17, 2019, the center hosted the 2019 China Japan steel structure application and development seminar hosted by China Steel Structure Association.

At the same time, relying on the national enterprise technology center of MCC group, the center combines the technical forces of enterprises such as steel structure and prefabricated building in the province, takes the steel structure prefabricated building and its supporting materials and parts as the main research direction, and gathers outstanding talents inside and outside the province, so as to build it into the most important research institution in the field of prefabricated building in the province It is the most influential first-class academic research center and scientific research cooperation base in the field of assembly development in Southwest China.

The new structural system introduced in the center: flat steel pipe column – narrow flange H-shaped steel beam – support has successfully broken through the limitations of “convex beam and convex column” of traditional steel structure residence.

The center is striving to become a first-class platform based on the western region, affecting the whole country and radiating the “one belt and one way” market.

At the same time, the center also has international leading scientific and technological achievements such as “one-time forming process and high-altitude installation technology of positive and negative arc curved surface vertical locking color steel profiled plate” and “production of high-precision track steel structure box girder”; It also has a complete set of technologies such as national construction method “high position and long-span cantilever steel structure construction method”, provincial construction method “high position and long-span cantilever steel structure construction method”, “steel truss cantilever support construction method”.

On April 18, 2019, the center successfully hosted the first steel structure development forum in Sichuan Province, and conducted exchanges and discussions around the development policy, technological innovation and development path of steel structure industry in Sichuan Province.
