Flexible joint of prestressed steel cable anchorage device
The invention discloses a prestressed steel beam anchorage device flexible joint, and relates to the technical field of prestressed tension anchoring, the prestressed steel beam anchorage device flexible joint comprises a perforated anchor plate and two semi-conical flexible fusion bodies, the perforated anchor plate is provided with a plurality of anchor holes, the inner walls of the anchor holes are conical surfaces and meet the self-locking angle requirement, the outer walls of the semi-conical flexible fusion bodies are matched with the inner walls of the anchor holes, and the outer walls of the semi-conical flexible fusion bodies are matched with the outer walls of the anchor holes. And the prestressed steel beam is clamped between the two semi-conical flexible fusion bodies. When the prestressed steel beam is stretched, the semi-conical flexible fusion body is driven to move along the axis of the anchor hole, the semi-conical flexible fusion body is embedded into the anchor hole, and in the process, the outer wall of the semi-conical flexible fusion body transmits the movement, so that the axial movement of the semi-conical flexible fusion body is converted into closing close to the axis of the anchor hole in the radial direction; the inner wall of the semi-conical flexible fusion body is engaged with the surface of the prestressed steel beam, so that flexible connection with the prestressed steel beam is realized, and the flexibility and fatigue life of the joint are improved.
本发明公开了一种预应力钢束锚具柔性接头，涉及预应力张拉锚固技术领域，包括开孔锚板以及两个半锥形柔性融合体，开孔锚板上设有多个锚孔，锚孔内壁为圆锥面且满足自锁角要求，半锥形柔性融合体外壁与锚孔内壁相适配，预应力钢束被夹持于两个半锥形柔性融合体之间。本发明中拉伸预应力钢束时，带动半锥形柔性融合体沿锚孔轴线运动，将半锥形柔性融合体嵌入锚孔中，在此过程中，由半锥形柔性融合体外壁传递运动，使得半锥形柔性融合体的轴向运动转变为沿径向靠近锚孔轴线收拢，半锥形柔性融合体内壁与预应力钢束表面咬合，实现与预应力钢束的柔性连接，提高连接处的柔韧性与疲劳寿命。
