Connector and method for connecting unbonded prestressed steel strands in post-cast strip
The invention provides a connector and method for connecting unbonded prestressed steel strands in a post-cast strip. The connector comprises a first anchor plate and a second anchor plate, wherein the first anchor plate is arranged on one side of the post-cast strip and applies tensile force in the first direction to a first-end steel strand, and the first anchor plate is fixedly connected with the first-end steel strand in the post-cast strip; the second anchor ring is fixedly connected with a second-end steel strand in the post-cast strip and applies tensile force in the second direction to the second-end steel strand; the two ends of the first anchor plate and the two ends of the second anchor ring are fixedly connected with the connecting structure. The steel strand and the first anchor plate are connected through the clamping piece, and the requirement for the embedding precision of the steel strand in the length direction is low through the structure. And the anchor plate is sealed in the sleeve and is not interfered by concrete pouring of the post-cast strip, so that the reliability is high. The anchor plate is fixed in the anchor plate hole, and the anchor plate is uniformly stressed, so that the prestressed steel strand does not bend, and the reinforcing steel bar does not generate normal stress in the concrete.
本发明提供一种用于后浇带内连接无粘结预应力钢绞线的连接器及方法。该连接器包括：设置在后浇带的一侧并对第一端钢绞线施加第一方向的张紧力的第一锚板，所述第一锚板与后浇带中的第一端钢绞线固定连接；还包括与后浇带中的第二端钢绞线固定连接，并对第二端钢绞线施加第二方向的张紧力的第二锚环；所述第一锚板和第二锚环的两端分别与连接结构固定连接。本发明的钢绞线和第一锚板采用夹片连接，这种构造对钢绞线长度方向埋设精度要求低。锚板封闭在套筒内，不受后浇带混凝土浇筑的干扰，可靠性高。锚板固于锚板孔中，锚板受力均匀，因此预应力钢绞线不存在弯曲，钢筋也就不会在混凝土中产生法向应力。
