Prestressed steel strand anchor rod and construction method thereof
The invention provides a prestressed steel strand anchor rod and a construction method thereof. The prestressed steel strand anchor rod comprises a rod body and a prestressed steel strand, the prestressed steel strand is provided with a plurality of anchor cables, and the prestressed steel strand anchor rod is characterized by further comprising a first pressure bearing plate, a second pressure bearing plate, a clamping piece anchorage device, a supporting clamping plate and an extrusion anchor, the anchor cables of the prestressed steel strand penetrate through the first pressure bearing plate one by one and are tensioned at the first pressure bearing plate, and the extrusion anchor penetrates through the second pressure bearing plate. The clamping piece anchorage device locks the tensioned prestressed steel strand at the upper end of the first bearing plate; the multiple anchor cables penetrate through the supporting clamping plate one by one and then are sequentially arranged on the second pressure bearing plate and the extrusion anchor in a sleeving mode, and the supporting clamping plate is arranged above the clamping piece anchorage device through resilience force of the anchor cables. Two anchorage devices are arranged, the first anchorage device locks prestress, and the second anchorage device is used for preventing the bearing plate from falling off; the advantages of a clamping piece anchor and an extrusion anchor are fully utilized, and the anchor rod can be well constructed before a bottom plate.
本发明提供一种预应力钢绞线锚杆及其施工方法。所述预应力钢绞线锚杆包括杆体和预应力钢绞线，所述预应力钢绞线具有多根锚索，其特征在于，还包括第一承压板、第二承压板、夹片锚具、支撑卡板和挤压锚，所述预应力钢绞线的多根锚索一一穿过第一承压板并在所述第一承压板处张拉，所述夹片锚具在所述第一承压板上端将张拉的预应力钢绞线锁定；多根所述锚索一一穿过所述支撑卡板后依次套设所述第二承压板和挤压锚，所述支撑卡板利用锚索的回弹力设置在夹片锚具的上方。本发明设置两道锚具，第一道锚具锁定预应力，第二道锚具为防止承压板脱落；充分利用了夹片锚与挤压锚的优点，可较好地实现锚杆先于底板施工。
