Tapped RB thread hexagon body yellow zinc plated and made of the hex steel bar with the internal RB thread from RB 10 to RB 30 supplied with special size as customers' inquire,designed to connect 2 steel rebars in the reinforced concrete site of the construction project.
The outer hexagon steel rebar coupler is made of outer hexagon solid steel bar, and the CNC machine tool is used to tap the inner RB thread which can fasten the steel rebar according to different specifications of rebar thread. This design is convenient in the construction site. It can directly connect the two rebars, without making the head of the rebar into the external bolt for fastening connection.
标准锥螺纹接头适用于连接两个相同直径的杆件,其中一个杆可以旋转。它包括一个带有两个右手的内螺纹套筒向连接器中间逐渐变细的螺纹。杆端为方形切口在杆上切下一个锥形螺纹。在钢筋穿线车间,耦合器通常被扭转到钢筋上,内部塑料端盖保护的螺纹。连续杆的螺纹端受到保护塑料螺纹保护器。连杆内的杆啮合通过锥形螺纹设计简化,有助于对准。当连杆在联轴器内完全接合时,继续杆被拧紧使用扭矩扳手。
The standard taper thread joint is suitable for connecting two members of the same diameter, one of which can rotate. It consists of a female sleeve with two right hand threads tapering toward the middle of the connector. The rod end is a square cut and a tapered thread is cut on the rod. In the steel threading workshop, couplers are usually twisted onto the steel bars, with internal plastic end caps protecting the threads. The threaded end of the continuous rod is protected by a plastic thread protector. The engagement of the rod in the connecting rod is simplified by the tapered thread design to facilitate alignment. When the connecting rod is fully engaged in the coupling, the continuing rod is tightened using a torque wrench.
钢筋混凝土结构中使用钢筋耦合器代替普通钢筋搭接接头。耦合器也适用于钢筋混凝土柱和墙。每个钢筋连接件由一根钢筋组成,从安装方向看,钢筋的右端配有螺纹和连接套。在施工缝中,钢筋接头可用来代替穿过模板的所有钢筋
In reinforced concrete structure, steel rebar coupler is used instead of common steel lap joint. Couplers are also suitable for reinforced concrete columns and walls. Each rebar connector is composed of one rebar. From the installation direction, the right end of the rebar is equipped with thread and connection sleeve. In construction joints, reinforcement joints may be used instead of all reinforcement passing through the formwork.
