摘　　要：对Ф75mm圆钢机械连接接头进行了型式检验。目前我国还没有出台大直径圆钢机械连接接头型式检验技术规程,参照《钢筋机械连接通用技术规程》JGJ107—2003,对试验过程和方法进行了有意义的尝试和探索,成功地完成了圆钢机械连接接头型式检验各单项内容,由于该圆钢直径特别大,在某种意义上填补了国内该项试验的空白。Through testing the type inspection of the Ф75 round steel mechanical joints, as for China has not yet established type inspection technical regulations of large-diameter round steel mechanical joints, Referring to General Technical Specification for Mechanical Splicing of Bars JGJ 107—2003. Meaningful exploration for the process and methods, successfully accomplished the items of the type inspection is presemted. Due to the particularly large diameter round bar, in a sense, the test fills the domestic blanks of this kind of tests.
