by On the afternoon of May 27, the Municipal Bureau of urban and rural development held a briefing on the evaluation results of standardized construction of prefabricated building prefabricated component manufacturers in Anhui Construction Engineering Beicheng Industry Co., Ltd., at which two enterprises, Anhui Construction Engineering Beicheng Industry Co., Ltd.
and Anhui Construction Engineering Zhonglun Intelligent Manufacturing Co., Ltd., with outstanding standardization construction, were organized to observe the planning and construction, information management The implementation of standardization such as intelligent production line and process quality control, reported the evaluation results of standardization construction of prefabricated building component manufacturers, and put forward suggestions for the next step.
In April this year, the Municipal Bureau of urban and rural development organized experts in production, testing, design and other aspects to carry out a comprehensive evaluation on the standardization construction of 11 precast concrete component manufacturers in Hefei according to the requirements of the manual for standardization construction and evaluation of prefabricated concrete component manufacturers in Hefei.
Among them, 4 are class A (comprehensive score ≥ 85), accounting for 36.4%, and 5 are class B (comprehensive score 80-85), accounting for 45.4%, Two enterprises of class C (comprehensive score 70-80), accounting for 18.2%; The highest score is 92 points, and the lowest score is 78.5 points; No substandard basic projects and one vote veto projects have been found, which shows that the standardization construction of prefabricated component production enterprises in our city has achieved remarkable results.
Comprehensive evaluation results of standardized construction of prefabricated component production enterprises from the evaluation results, the quality, environment, occupational health and safety management system and various management systems of prefabricated concrete component production enterprises in our city have been established, the plant layout has been managed by zones, the management department is fully staffed, the production equipment meets the requirements, the quality control has been strengthened, the safety management has been strictly implemented, and the plant environment has been effectively improved, Information management is widely used.
Among the 51 sub items of the 10 evaluation categories of each production enterprise, there is no lack of standardization construction, and the component production quality is generally controlled, showing a steady improvement trend.
Prefabricated components are widely used in many demonstration projects such as honglianyuan shanty town reconstruction, yudeya garden, Longwang Tanggang reconstruction site, Binhu Qinyuan, Feixi talent apartment, Feidong Zhenxing community rental housing, and other key projects such as Hefei rail transit lines 3, 7 and 8, providing a strong guarantee for the high-quality development of assembled buildings in Hefei.
The industrial support capacity has been continuously enhanced.
There are 55 production lines (31 assembly lines, 24 fixed lines, including 4 segment lines) for prefabricated concrete components of prefabricated buildings in our city, with an annual design capacity of 2.6 million cubic meters (including 400000 cubic meters of shield segment); According to the assembly rate of 30%-50%, it can meet the construction requirements of prefabricated concrete buildings with an area of more than 15million square meters; From January to April, the cumulative production of prefabricated concrete components in the city was 177900 cubic meters, providing a strong and effective guarantee for the construction of prefabricated concrete construction projects in the city.
The construction of talent team has been promoted orderly.
In recent years, the city has trained more than 2300 qualified grouting workers, hoisting workers and component fabricators by holding vocational skills competitions, specialized technical training and other effective forms.
According to statistics, by the end of 2021, there were more than 1900 employees engaged in the production of prefabricated components in our city, including more than 1700 on-the-job industrial workers (more than 290 with corresponding job certificates), and nearly 250 technical management personnel (including 28 with senior titles, 81 with intermediate titles and 77 with primary titles), providing a strong talent guarantee for the healthy development of prefabricated buildings.
In the 2021 provincial prefabricated building vocational skills competition, the municipal team won all the first prizes, 11 second prizes and 11 third prizes at one fell swoop, leading other teams remotely, fully demonstrating the achievements of the construction of the prefabricated building talent team in our city.
The quality management of the third prefabricated building vocational skills competition in Hefei has been steadily improved.
Over the past few years, Hefei has promoted enterprises to implement various quality management through carrying out expert “one-to-one” activities, “double random” inspections, factory supervision system, enterprise standardization construction and other work.
Through the evaluation and inspection, it is found that the enterprises have established a quality management system, formulated the production and quality control scheme of project components, the quality acceptance procedures of key processes and nodes, and the delivery inspection system.
Throughout the year, the first piece acceptance and factory supervision of prefabricated components were carried out, and the results became more and more obvious; The standardized construction of enterprise laboratories has been further improved, and the testing ability has been continuously improved; The component quality is generally under control, and the quality management is steadily improving.
In recent years, the prefabricated buildings in our city have won 1 national high-quality project award, 2 Huangshan cups, 6 AMBER cups, 18 high-quality structure awards, and 27 provincial prefabricated demonstration projects.
Technological innovation has been continuously promoted.
At present, the city’s concrete prefabricated component production enterprises have been approved three national prefabricated building demonstration bases and five provincial comprehensive demonstration bases; It has won five national “high-tech enterprises”, one national technology center and four municipal technology centers.
It has carried out 67 R & D and application of new technologies and construction methods, applied for and granted 219 patents for inventions, utility models and appearance designs, edited and participated in the compilation of 36 standards and specifications.
The application rate of the information-based production management system has reached 100%, the production management efficiency has been significantly improved, and the endogenous power of the enterprise has been continuously enhanced, It has effectively promoted the high-quality development of prefabricated buildings in the city.
The residential buildings in Yuxiu Yayuan community of Xinzhan high tech Zone are all constructed by assembly technology..
