Annular prestressed anchorage device mounting process
The invention discloses a circumferential prestressed anchorage device mounting process, and belongs to the technical field of constructional engineering. According to the technology, each steel strand is a U-shaped steel strand, a first annular prestressed anchorage device and a second annular prestressed anchorage device are arranged on the two sides of a bearing body of each steel strand, and a strand section of the anchoring end where the first steel strand is located and a strand section of the tensioning end where the second steel strand is located are connected with a first annular prestressed anchorage device and a second annular prestressed anchorage device respectively. The anchor holes respectively penetrate through the first circumferential pre-stressed anchors; the stranded wire section of the tensioning end where the first steel strand is located and the stranded wire section of the anchoring end where the second steel strand is located penetrate through anchorage device holes of a second circumferential pre-stressed anchorage device respectively; and after each steel strand is perforated, an anchor backing plate and a clamping piece are installed at the anchoring end and the tensioning end correspondingly, and fixing and clamping are conducted. The two sides of the bearing body of each steel strand bear the same prestress in the tensioning process, and the stability of the bearing body on the internal structure is guaranteed.
本申请公开了一种环向预应力锚具安装工艺，属于建筑工程技术领域。该工艺每根钢绞线为U型钢绞线，所述第一环向预应力锚具和所述第二环向预应力锚具在所述每根钢绞线的承载体的两侧，将第一根钢绞线所在锚固端的绞线段，以及第二根钢绞线所在张拉端的绞线段，分别穿过第一环向预应力锚具的锚具孔；将所述第一根钢绞线所在张拉端的绞线段，以及所述第二根钢绞线所在锚固端的绞线段，分别穿过第二环向预应力锚具的锚具孔；待每根钢绞线都完成穿孔后，在所述锚固端和所述张拉端处分别安装锚垫板和夹片，进行固定夹紧。使所述每根钢绞线的承载体的两侧在张拉过程中承受同样大小的预应力，保证了承载体在内部结构上的稳定性。
