A piece of neat and soft cloth is carefully cut by a tailor according to the design to make beautiful clothes. Ren Xiangfu, a national technical expert, is known as the "Steel Tailor". He said that he was a tailor, but the raw material was steel. It is not difficult to cut cloth into clothes, but it is a bit unthinkable to change it into cold, stiff steel and transform it into a huge building. How do they become flexible under the Iron Tailor?
Migrant workers become senior technicians
Today, Ren Xiangfu is a senior cold work technician at MCC Construction Group Steel Structure Company. He is recognized as a technical expert and many peers in the industry will honor him. As "Master Ren". In fact, he is indeed a master. As early as November 2013, he founded the Ren Xiangfu Leng Work Skills Master Studio and was promoted to a national-level skills master studio in September 2015.

From working as an ordinary riveter to the present, Ren Xiangfu has served as squad leader and foreman. From 1987 to the present, he has continued to learn, explore and summarize in practice, and has accumulated rich experience in the production and installation of steel structures. He is especially familiar with the control and correction technology of various deformations in fabrication, and is recognized as a technical expert.
"More than 30 years ago, I was an ordinary migrant worker. In 1987, I entered MCC18 (the predecessor of MCC Construction) as a migrant worker and became an ordinary Leng Zuogong. I had just graduated from a vocational high school, and I was still studying fruit tree cultivation technology. I had never been exposed to the profession of Leng Zuogong. "Ren Xiangfu told the reporter of Upstream News and Chongqing Evening News that after learning from the master for half a year, he started working in the mine. The installation work was left to him. Over the decades, while exploring and learning, he has gradually reached the top of the pyramid of cold work industry.
Steel Tailors Don’t Waste Leftovers
“As you know, tailors who make clothes, we are actually tailors too. Although the things we cut are different, the principle is the same. It cannot be wasted.” Ren Xiangfu told us that he was also a tailor, but he only cut steel.

Can stiff and cold steel be cut freely? As a steel tailor, Ren Xiangfu knows the entire tailoring process by heart. After getting the drawings, identifying them, cutting materials, and assembling them, a work is completed. "Cutting materials is the same as making clothes. It cannot be wasted. The leftover materials should also be used well. If the cutting is unreasonable, it will be wasted, and it is a pity that the materials will be wasted."
"Society is changing too fast, and you must recharge yourself in time. , Improve comprehensive skills. Computer drawing theory and software are slowly explored. "Ren Xiangfu didn't know anything about computers at first. Now, among the on-site construction workers of his age, he is the most familiar with computers and can use CAD proficiently. Many problems were solved for the smooth construction of the project. Although he is 52 years old, Ren Xiangfu still uses his time after dinner to continue studying.
Overcoming construction problems
It is understood that with his drive to learn and drill and his passion for innovation, Ren Xiangfu has overcome various technical problems in the work of more than 20 key projects. Nearly 30 years of front-line work experience and superb skills have made him an expert technical talent.
Among these key projects are the well-known Niujiaotuo Station Phase I of Rail Transit Line 3 and Chongqing International Circus City. "The Niujiaituo Station of Line 3 has a total steel structure of only 200 tons, 14 curtain wall panels, and a curtain wall area of ??3,000 square meters. It is just a small project, but 4 panels in the project are located above the operating light rail Line 2. The plate is less than one meter away from the edge of the heavily trafficked Yu'ao Bridge," Ren Xiangfu recalled. Not only was it impossible to use a crane during construction, but there were also major safety hazards. After repeated consultations with the engineering and technical personnel, he finally produced a soil lifting rod for lifting components of the project, overcoming the problem of being unable to use mechanized construction. “It won’t affect traffic, but construction will only take place at night, from 10:30 p.m. to 6 a.m.

Magical “Alien Building”
Chongqing International Circus City is the third high-standard acrobatic performance venue under construction in my country after Shanghai and Guangzhou. It is located at Danzishi on Nanbin Road The International Circus City adopts a double-layer shell structure and looks like a lying "egg". Because of this rare shape, it is called the most difficult and complex "abnormal building". The team overcame this problem in just half a year and turned Chongqing International Circus City from paper into reality.
It is understood that building a steel structure building with arc-shaped exterior walls is a construction challenge. The difficulty is that the Chongqing International Circus City is composed of two arcs. Each keel must have different curvatures and show different twists. The shape of the building is a complex spatial special-shaped steel structure, and the overall shape is unique. It is a steel structure building. The so-called "abnormal shape" means that none of the keels are horizontal or vertical. They are all abnormally shaped and there is no unified standard. "Ren Xiangfu said that the Circus City project has high requirements for the curvature of steel bars. He has been working in this industry for more than 30 years, and he can understand it if he reads ordinary construction drawings two or three times. As for the design drawings of the International Circus City, it took more than a month to understand it. In order to process such a special structure, Ren Xiangfu and his team used two 1,000-ton hydraulic jacks to tailor-design two top-bending devices and an overall space-assembled tire frame. The design and success of the device obtained the national utility model patent
The spirit of craftsmanship cannot be lost
It is understood that Ren Xiangfuleng’s workmanship skills master studio relies on MCC Construction Engineering Group Co., Ltd. The company was founded in November 2013 and was promoted to a national-level skill master studio in September 2015. “The studio mainly includes four locations: offices, multimedia classrooms, training bases, and production workshops. Responsible for tasks such as enterprise technology research and development, skills training, mentoring and apprenticeship training, and student internships in factories. "Li Yingzhu, the relevant person in charge of the Steel Structure Company of MCC Construction Engineering Group, said that it is difficult for "steel tailors" to deal with steel. On the one hand, enterprises have higher requirements for talents and have a greater demand for talents. But on the other hand, talents Don’t want to come in. “Platforms like Skill Master Studio provide a platform for our skilled talents to display, and at the same time provide honors, which play an important role in driving and attracting talents. "Li Yingzhu said.
Ren Xiangfu has more than 30 years of front-line work experience, and the working environment has also undergone tremendous changes. Nowadays, many companies are mechanized operations, but in his view, no matter how advanced the machine is, it requires people. To operate, no matter how advanced the technology is, the spirit of craftsmanship cannot be lost. “Each steel component is different, such as length, height, depth, etc. These can only be achieved by skilled craftsmen. ”
