In order to further improve the understanding of all employees of the company on product quality, To strengthen the core values of Zhongjiang assembly, namely “customer first, quality perfection and talent strength”, the company launched the “component process production process” on the morning of January 15, 2022 Thematic training.
The main lecturer of this training is Xie Jianzhong, engineer of Arts and crafts Quality Department of the company.
Xie Jianzhong: graduated from the school of civil engineering of Xi’an University of architecture and technology, majoring in civil engineering.
He once worked in China Construction Group and Jiangsu Zhongying Tongjian.
The three main contents of this training: first, compared with developed countries, the penetration gap of prefabricated buildings in China is large, and there is huge room for improvement.
In recent years, China’s prefabricated construction industry is developing rapidly.
In recent years, under the background of continuous promotion of policies and continuous upgrading of construction technology, China’s prefabricated building area and industry scale have ushered in rapid development.
Comparison of China’s prefabricated building penetration rate with major developed countries (2017) △ (data source: public data collation) China’s newly-built prefabricated building area has increased rapidly in recent years △ (data source: public data collation) the scale of prefabricated buildings and supporting industries (RMB 100 million) has developed rapidly △ (data source: public data collation) The continuous growth of China’s construction industry has brought new opportunities and challenges to the development of prefabricated buildings.
At present, precast concrete (PC) structure is still the mainstream of prefabricated buildings in China.
Vigorously promoting PC structure can significantly reduce the dust and noise pollution in the current cast-in-situ concrete construction project, save energy and reduce consumption, and plays an important role in the popularization of building industrialization in China.
2、 Production process flow of prefabricated components Xie Jianzhong mainly introduced the production process flow and operation instructions of the top three products of our company: laminated plate, shear wall and prefabricated stair slab.
△ (production process flow chart) the fabricated construction industry itself is an industry that needs a lot of technical support and large-scale effect.
Whether it is design, equipment manufacturing or production and installation, it needs mature technology for support.
The strict quality management system is invisible to consumers.
We need to carry out plant planning and investment cost estimation according to requirements and land status, provide all process contents of precast concrete component products, and provide production system planning according to capacity demand and production process characteristics.
3、 Future development of prefabricated buildings in 2018, China’s newly built prefabricated buildings will cover an area of about 190 million square meters, and the market space is expected to be about 475 billion.
According to the policy objectives, the proportion of prefabricated buildings in new buildings will reach more than 15% by 2020 and 30% by 2025.
Assuming that the new construction area will not increase from 2018, and the cost per square meter will be 2500 yuan, It is estimated that the corresponding market space in 2020 / 2025 will be 784.9 billion yuan and 1.57 trillion yuan respectively.
The average growth rate of the industry from 2019 to 2020 will be nearly 30%, and the fabricated construction industry will continue to develop rapidly.
In 2025, the market space of prefabricated buildings is expected to reach 1.57 trillion yuan (unit: 100 million yuan) △ (data source: public data sorting).
In this training, manager Xie Jianzhong carefully prepared rich course contents and courseware, and made everyone more vividly understand the process of prefabricated buildings through on-site explanation and video The production process of prefabricated building components and the on-site construction and installation of prefabricated buildings.
The participants participated, interacted and recorded in the whole process, and said that they had greatly expanded their professional field, and had a better understanding of the company’s strict requirements on product quality, which increased their confidence!..
