Prestressed anchor rod tensioning and locking structure and method
The invention provides a pre-stressed anchor rod tensioning and locking structure which comprises a concrete cushion layer laid below a basement bottom plate, a steel plate is arranged on the concrete cushion layer, a stirrup steel plate for supporting a hydraulic jack is fixed to the steel plate, a pre-stressed anchor rod penetrates through the concrete cushion layer, the steel plate and the stirrup steel plate, and a first anchoring plate is fixed to the top end of the pre-stressed anchor rod. The hydraulic jack is located between the first anchoring plate and the stirrup steel plate, the prestressed anchor rod tensioning and locking structure further comprises a nut used for locking the prestressed anchor rod, and the nut is tightly attached to the steel plate. The invention further provides a pre-stressed anchor rod tensioning and locking method.
本发明提供一种预应力锚杆张拉锁定结构，包括地下室底板下方铺设的混凝土垫层，混凝土垫层上设有钢板，钢板上固定有支撑液压千斤顶的马镫钢板，预应力锚杆贯穿混凝土垫层、钢板、马镫钢板，预应力锚杆的顶端固定有第一锚固板，液压千斤顶位于第一锚固板和马镫钢板之间，预应力锚杆张拉锁定结构还包括用于锁定预应力锚杆的螺母，螺母紧贴钢板设置。本发明还提供一种预应力锚杆张拉锁定方法。
