Steel strand anchoring structure and application thereof in post-tensioned prestressed bent cap
The invention discloses a steel strand anchoring structure and application of the steel strand anchoring structure in a post-tensioned prestressed bent cap. The steel strand anchoring structure is used for solving the problem that a clamped steel strand slides when an existing steel conical anchorage device is used for anchoring. The steel strand anchoring structure comprises a steel base plate, a base, an anchor ring, an anchor plug and a clamping piece, the anchor ring is composed of a flange part and a frustum part, the flange part is provided with an unthreaded hole, the flange part and the base are provided with annular matching faces, the anchor ring is synchronously fixed through a high-strength bolt I, the frustum part is provided with a conical hole, the anchor plug is arranged in the conical hole, and the clamping piece is arranged in the conical hole. A threaded hole is formed in the outer end face of the frustum part, and a clamping piece is fixedly mounted through a high-strength bolt II; the anchor plug is composed of a plurality of sub-modules, a gap is formed between every two adjacent anchor rings, and the sub-modules are enclosed to form a steel strand channel; and the five sub-modules in the anchor plug are accurately adjusted, so that the problem of sliding of the clamped steel strand during anchoring is solved.
本发明公开了一种钢绞线锚固结构及其在后张法预应力盖梁中的应用，用于解决现有钢制锥形锚具在锚固时存在的对夹紧钢绞线存在的滑动问题。该钢绞线锚固结构包括钢垫板、底座、锚环、锚塞和夹片，其中，锚环是由法兰部和锥台部组成的，其中，法兰部设置有光孔，该法兰部与底座具有环形的配合面，高强度螺栓Ⅰ同步的对锚环进行固定，锥台部具有圆锥孔，该圆锥孔内配置锚塞，以及在锥台部的外端面上设置有螺纹孔并通过高强螺栓Ⅱ固定安装夹片；锚塞是由多个子模块组成的，且相邻的锚环之间具有间隙，子模块围合形成钢绞线通道；通过对锚塞中的五个子模块进行精准的调节，解决了锚固时存在的对夹紧钢绞线存在的滑动问题。
