On September 23, 2020, the compilation group of "steel bar straight thread connection sleeve" of China Engineering Construction Standardization Association was established! The first working conference was held in the mechanization branch of China Academy of Building Sciences in Langfang.
Hebei Jingye Xinde Reinforcement Engineering Co., Ltd., as a participant, actively participated in the discussion meeting of reinforcement sleeve standard, and made suggestions and suggestions for improving the quality and standard of steel bar connection.
With the support of the leaders of relevant departments and the joint efforts of the members of the preparation group, the first working meeting of the standard preparation group successfully completed the scheduled schedule, discussed and passed the preparation outline, task division and preparation progress, which laid a good foundation for the next step of standard preparation work.
The meeting was held by Zhu Aiping, Secretary General of concrete structure Professional Committee of China Engineering Construction Standardization Association, and Liu Zijin and Wang, deputy director of certification center of China Academy of Building Sciences Bo, Li Zhibin, deputy general manager of Jianyan science and Technology Co., Ltd., Zhao Jie, senior engineer, Zhao Hongxue, Secretary General of reinforcement and prestressed machinery branch of China Construction Machinery Industry Association, Cui Dekui, senior engineer of national construction engineering quality supervision and inspection center, Liu chenghuan of Beijing Construction Mechanization Research Institute Co., Ltd., and Hebei Jingye Xinde Reinforcement Engineering Co., Ltd.
Zhu Aiping, Secretary General of the concrete structure Professional Committee of China Engineering Construction Standardization Association; Liu Zijin, chief editor, presided over the first working meeting of the preparation group; and Zhao Hongxue, Secretary General of the reinforcement and prestressed machinery branch of China Construction Machinery Industry Association, presided over the discussion on key issues of standards.
The meeting provides technical basis for further standardizing the market and improving the quality and stability of joint. It is of great significance to increase the ex factory ductility index inspection of sleeve, increase the sleeve flattening test requirements and inspection methods, meet the engineering quality and safety requirements, ensure the stability of joint strength, promote the healthy development of the steel bar mechanical link industry, and organize the industry to prepare this group standard.
