The connector assembly comprises a pressure seat and a transition piece which are arranged at an interval, the pressure seat comprises a pressure frame, a pressure bearing plate and an end plate, the pressure bearing plate and the end plate are installed at the two ends of the pressure frame, a jack is detachably installed in a force application cavity, and a piston hole is formed in the end plate; the end plate and the end plate are parallel to each other or form an included angle less than or equal to 5 degrees; the two ends of the tension bolt are connected to the pressure base and the transition piece respectively. The joint assembly can be mounted between the horizontal support and the structural member and is used for applying prestress to the horizontal support; and after the transition piece is pushed, high-early-strength grouting materials are poured into gaps between the end plates and the end head plates, and grouting material pouring blocks are formed. The invention further discloses a method for applying the prestress to the horizontal support through the connector assembly. In the application, the grouting material pouring block is used for replacing the existing steel wedge, so that the prestress in the horizontal support and the structural member is kept stable.
本发明公开了一种用于施加预应力的接头组合件，其包括间隔设置的压力座和过渡件，压力座包括压力框和安装在压力框两端的承压板和端头板，千斤顶可拆卸地安装在施力腔内，在端头板上开设有活塞孔；端板与端头板相互平行或具有一个≤5°的夹角；张力螺栓的两端分别连接在压力座和过渡件上；接头组合件能够安装在水平支撑与结构件之间，用于对水平支撑进行预应力施加；当对过渡件完成顶推后，在端板与端头板之间的间隙内浇注高早强灌浆料，形成灌浆料浇注块。本申请还公开了采用接头组合件对水平支撑进行的预应力施加方法。本申请中，利用灌浆料浇注块来替代现有的钢楔子，使得水平支撑和结构件内的预应力保持稳定。
