The rise of green assembly building highlands in Jimo District, Shandong Province, towards the "black lamp factory" and "unmanned factory"

Walk into the new factory of Zhongqing Hangxiao Green Building Technology Co., Ltd. (hereinafter referred to as Zhongqing Hangxiao) located in Lancun Street, Jimo District, Qingdao City. I saw two 20,000 square meters workshops, 8 assembly steel component production lines are running at full capacity, outside the workshop, a truck is waiting for loading...

"At the beginning of this year, since we moved into the new factory area, our company has been in full capacity production due to the expansion of production capacity and doubled orders," said Cui Rongxing, general manager of the company.

However, what makes reporters strange is that in the state of full production, there are fewer than 200 workers in blue overalls in the two huge production workshops, which is very different from the scale of employment of thousands of people in traditional construction companies. "This is mainly due to the deep integration of informatization and industrialization." Cui Rongxing said bluntly.

Indeed, in Zhongqing Hangxiao, informatization and industrialization "elements" are everywhere. In 2017, the company invested 33.5 million yuan in the first year of its establishment to build an automated production line for green assembled steel components. Adopt OA/ERP data information transmission system to realize the collection, monitoring and transmission of production, material and office data, and build a world-class "black light factory" and "unmanned factory". Workers can achieve precise and efficient operations with a single click of the mouse, achieving "one person in charge of one machine" or even "one person in charge of multiple machines". While improving production efficiency, it has also achieved output increase and output value growth.

As the first batch of prefabricated construction industrial bases in Qingdao, Zhongqing Hangxiao is mainly engaged in the R&D, design, manufacturing and installation services of high-rise super high-rise steel structure prefabricated residential buildings and steel structure prefabricated office buildings. With advanced technical support and perfect operating mechanism, companies have more and more opportunities to participate in the construction of key surrounding projects. In just three years, they have quickly become a leader in the industry.

The Haike Plaza project in Qingdao Blue Valley has now entered an intense construction finishing stage. Among them, 6 residential buildings with a height of one hundred meters are designed, manufactured and installed by Zhongqing Hangxiao, and adopt the third-generation steel tube bundle composite structure residential system independently developed by Hangxiao Steel. This is also the first industrialized prefabricated high-rise steel structure residential EPC project in Qingdao's housing construction engineering field, marking the official opening of Qingdao City's prefabricated steel structure residential development.

It is reported that, compared with the traditional cast-in-place structure, the prefabricated steel structure residential building is composed of steel tube bundle composite structure shear wall and H-shaped steel beam and other main structures. The steel structure is built like building blocks, and then installed with insulation boards, anti-corrosion layers, and exterior wall paint to form a high-efficiency residential system. It has the advantages of environmental protection and energy saving, fire prevention and corrosion protection, short construction period, good heat preservation effect, and good seismic performance. While greatly reducing the construction cost, it also shortened the construction time, reducing about 80% of construction waste per square meter.

In addition, the support and guidance of local government departments have built a platform for Zhongqing Hangxiao to give full play. It has successively participated in a large number of key land-port new city construction projects such as Qingdao Port Jimo Port Comprehensive Service Center, Lancun Science and Technology Innovation Service Center, Qingdao Metro Rail Transit Intelligent Maintenance Project. One by one, steel structure buildings representing the advanced level of the world have risen from the ground. While more and more people realize the charm of steel structure buildings, they also witness the comprehensive strength of Zhongqing Hangzhou.

The comprehensive service center of Qingdao Port Jimo Port District, which was officially opened in June this year, is located in Jimo International Dry Port. It includes a 9-story commercial office building, a 2-story podium and an underground garage. The building height is 40.9 meters. From April 29, 2019, when the hoisting conditions were met, construction began, and the structure was topped off on June 1 of the same year. The total construction period was 33 days. After deducting 5 days of force majeure, the actual construction period was 28 days, with an average of three days for one floor. The capping of the project was completed 7 days earlier than the planned construction period, creating a new speed in the construction of Lugang New City.

"Scientific and technological innovation is the source of power for enterprise development. We will continue to increase R&D investment, vigorously introduce high-level technical talents, apply for provincial enterprise technology centers, and carry out the green prefabricated construction business to the end." When asked about the company's next development, Cui Rongxing said.
