Abstract
Behind the "China speed" is the continuous innovation of China's construction technology. One key project, one national tool, one innovation breakthrough... In the great revolution of the new era, "seize the day" is the footnote of builders on speed. From following and running to leading, China's speed has set off a whirlwind of "Chinese efficiency" in the world. In the field of construction, "China's speed" results are flourishing, and "China's efficiency" is everywhere.
The intelligent terminal equipment production and processing project of Shanxi Transformation and Comprehensive Reform Demonstration Zone (hereinafter referred to as "Shanxi Comprehensive Reform Demonstration Zone"), which is designed by Shanxi Architectural Design and Research Institute, is one of the true portraits of "China speed" and "China efficiency".
Intelligent terminal equipment production and processing project, located in Xiaohe Industrial Park, Taiyuan City, Shanxi Province, is one of the provincial key "ten-billion intelligent terminal manufacturing industrial projects". The total investment exceeds 600 million yuan, the total land area is about 84,000 square meters, the total construction area is about 209,000 square meters, and the building height is about 23.9 meters. Including 7 multi-storey factory buildings, 1 power room, 3 dormitory buildings and supporting underground garage. Based on the construction of "standardized" factory buildings and dormitory buildings for employees, the project focuses on the 5G intelligent information technology industry and takes advantage of preferential policies of Shanxi Comprehensive Reform Demonstration Zone to build a multi-dimensional public service platform of "government, production, learning, research, application, capital and communication" for enterprises. After the completion of the project, it will further accelerate the industrial agglomeration of Shanxi Comprehensive Reform Demonstration zone, and provide strong support for Shanxi Province to build a modern industrial system supported by advanced manufacturing.
#1 Replicable construction concept with efficiency first
The construction period is tight, the volume is large, the quality requirements are high, the intelligent terminal equipment production and processing project construction process is the main characteristics. As one of the main persons in charge of the project, Yang Kun, architect of Shanxi Architectural Design and Research Institute, introduced to us that different from the general plant design, the plant design requirements of the project should conform to the production process of 5G intelligent manufacturing; Second, the construction period is only 4-5 months. "It's challenging for us to go from zero to one in a very large plant in a very short period of time."
Based on the construction concept of efficiency first, the project is planned and designed as a production workshop on four floors above ground, which is divided into two design modules of 3,000 square meters and 5,000 square meters. Yang general introduction, "Under the premise of meeting the production process requirements, the production plant will be 1:1 copy construction, further improve the construction efficiency." Through module replication, a single building area of 1#, 2#, 3# and 4# workshops has reached 20,000 square meters, and a single building area of 5#, 6# and 7# workshops has reached 12,000 square meters. The first floor of each workshop is 8.4 meters high, and the second, third and fourth floors are 4.8 meters high, which can be said to be a production workshop "tailored" for intelligent manufacturing production.
#2 Prefabricated "construction" certification of Chinese speed
When it comes to "China speed", prefabricated buildings have the first say. In 2020, when the novel coronavirus epidemic was rampant, the construction of Huoshenshan and Leishenshan, which mainly consisted of prefabricated steel structures, fully demonstrated the characteristics of prefabricated buildings, which are fast, efficient, safe and stable, green and energy saving. In recent years, under the guidance of the national "dual carbon" policy and the good news of policies issued around the country, prefabricated buildings have entered the fast track of development.
"The assembly rate of the intelligent terminal equipment production and processing project reached more than 70 percent, which is another bright spot of the project." General Manager Yang introduced to us that the main structure of the project adopts the steel frame-support structure system, and the floor is the composite slab of profiled steel sheet concrete. "The biggest technical difficulty of the project was the installation of the steel structure. The project construction is difficult due to its large volume, high installation accuracy requirements of column and beam joints, many cross-site operations and tight construction period." In order to overcome the technical "barrier" and run out of the "Chinese speed", the project team makes overall planning and unified layout: the technical team generates the site installation layout and component list through BIM technology, which greatly improves the processing speed and site construction speed of the steel structure; The measurement team uses theodolite and level to control the dimension and elevation of the axis of the steel column, and uses total station for fine correction, which improves the machining precision of the steel structure and the on-site installation precision. The construction team shall simultaneously construct the working surface of the workshop and carry out the flow operation to ensure that the project is completed on schedule and the quality of the project is all up to standard.
The production and processing project of intelligent terminal equipment successfully completed all node tasks and objectives, and won the honorary title of "Sanjin Model Steel Structure Project" in the second half of 2021 by Shanxi Steel Structure Association. The "China speed" reflected in the construction process is due to the extensive application of prefabricated steel structure buildings. With light weight, strong stability, short construction time, good seismic resistance, recycling and other advantages, prefabricated steel structure buildings show an increasingly important attitude in the field of green building.
#3 Green building materials are the icing on the cake for intelligent manufacturing
The report on the Party's 20th National Congress stressed the importance of promoting green and low-carbon modes of production and life. Construction industry is the key field of industrial energy consumption and carbon emissions, green development is an inevitable trend. Promote green building materials, reduce the consumption of natural resources and reduce the impact on the ecological environment in the whole life cycle of buildings, make them energy-saving, safe and recyclable, help promote the transformation and upgrading of the construction industry and accelerate the realization of the "double carbon" goal.
Industrial buildings should not only reflect the "Chinese speed", but also protect the safety of industrial production. The wall enclosure system of intelligent terminal equipment production and processing project selected Wiskind COLORGEM® Sandwich Panel series products and adopted vertical version curtain wall installation and construction method, in line with the continuity of the relationship between the project floors. General Manager Yang introduced to us, the selection of Wiskind COLORGEM® Sandwich Panel products as the wall enclosure material of the project, first, as a green energy-saving building materials and intelligent terminal equipment manufacturing industrial park in line with the positioning; On the other hand, mastercard Li color drill sandwich board products have good thermal insulation, wind resistance, fire prevention, waterproof performance, to provide security for industrial production safety, and the design of the four sides of the groove makes the board has excellent flatness, high installation accuracy, but also to ensure the beauty of the building facade.
#4 Conclusion
Behind the "China Speed" is the continuous innovation of China's construction technology, and the prefabricated building has long been the trend of The Times. At the National Conference on Housing and Urban and Rural Construction held in Beijing earlier this year, it was proposed to continuously improve the quality of construction in the direction of industrialization, digitalization and greening of the construction industry, and develop new construction methods such as intelligent construction and prefabricated construction. We have reason to believe that with the continuous improvement of digital technology, technological innovation and production process, prefabricated buildings will become mainstream soon.
