由上海市建委科学技术委员会和上海市工程建设标准化办公室主持,上海市隧道工程设计院负责主编的上海市标准《钢筋锥螺纹联接技术规程》,最近已获市建委批准,并于1994年4月1日起开始施行。 钢筋锥螺纹联接技术,是钢筋机械联接方式之一,它是将两根待联接的钢筋端头,在工地现场用专门的钢筋锥螺纹机床加工好锥螺纹,然后与预制好的锥螺纹联接套相联接,形成钢筋锥螺纹联接接头,简称锥螺纹接头。这种接头与常用的钢筋绑扎和钢筋搭接焊接接头工
The Shanghai Municipal Standard “Reinforced Taper Thread Connection Technical Regulations” edited by the Shanghai Municipal Construction Committee Scientific and Technical Committee and the Shanghai Municipal Engineering Construction Standardization Office, Shanghai Tunnel Engineering Design Institute, was recently approved by the Municipal Construction Committee and was completed in April 1994. It will be implemented on the 1st. The technology of steel reinforcement taper thread connection is one of the mechanical connection methods of steel bars. It is to connect two steel bar ends to be connected, and a taper thread is used to process the taper thread on the site with a special steel taper thread machine, and then it is connected with the prefabricated taper thread. Connected to form a rebar threaded joints, referred to as tapered threaded joints. This joint is commonly used with steel reinforcements and steel overlap welding joints.
