钢筋机械连接件拉伸试验的研究

Study on Tensile Test of Reinforcement Mechanical Connector

文中通过对三种不同的套筒厂家(GX、HR、JF)、三种不同的钢筋公称直径(22mm、25mm、28mm)、三种不同的接头等级(Ⅰ级、Ⅱ级、Ⅲ级)和三种不同的接头类型(BB、BY、DB)条件下钢筋机械连接件进行拉伸试验,研究不同条件下钢筋机械连接件的破坏部位、破坏状态和极限抗拉强度。

This paper studies the failure position, failure state and ultimate tensile strength of reinforcement mechanical connectors under the conditions of three different sleeve manufacturers(GX, HR and JF), three different nominal diameters of reinforcement(22mm, 25mm and 28mm),three different joint grades(gradeⅠ, Ⅱ and Ⅲ)and three different joint types(BB, BY and DB).
