Prestressed steel bar tensioning and anchoring device
According to the prestressed reinforcement tensioning and anchoring device, a base body is of a hollow cylindrical structure, an outer sleeve is arranged on the base body in a sleeving mode, and a clamping block is arranged on the outer sleeve and can stretch into the base body; the clamping block can be operated to do reciprocating motion in the radial direction relative to the outer sleeve so as to clamp and loosen the prestressed reinforcement; the outer sleeve can be limited to axially move relative to the base body before the clamping blocks clamp the prestressed steel bars, and can be operated to be released after the clamping blocks clamp the prestressed steel bars, so that the outer sleeve and the clamping blocks can jointly axially move relative to the base body, and tensioning of the prestressed steel bars is achieved. Therefore, the action that constructors complete clamping operation and the action that the constructors complete tensioning operation are consistent, continuity and integrity of the operation actions are guaranteed, meanwhile, dependence on the number and types of external tools is reduced, clamping and tensioning of reinforcing steel bars can be completed only through a single external tool, and operation simplicity and convenience are greatly improved.
本发明涉及一种预应力钢筋张拉锚固装置，其中基体为内部中空的筒形结构，外套筒外套设置在基体上，夹持块设置在外套筒上并且能够伸入到基体中；夹持块能够被操作相对于外套筒在径向上往复移动，以对预应力钢筋进行夹持和松脱；外套筒在夹持块对预应力钢筋形成夹持前能够被限制相对于基体进行轴向运动，而在夹持块对预应力钢筋形成夹持后能够被操作释放，以使得其能够与夹持块共同相对于基体进行轴向运动，实现对预应力钢筋的张拉。这使得施工人员完成夹持操作的动作和完成张拉操作的动作相一致，这保证了操作动作的连续性和整体性，同时也降低了对外部工具数量和种类的依赖，仅依靠单一外部工具即可完成对钢筋的夹持和张拉，操作简便性大大提高。
