Grid reinforced variable-diameter reinforcement cage and anchor rod
A grid reinforced type variable-diameter reinforcement cage comprises a set of vertical ribs, an axial rod, at least two sets of ribs with the same number and at least one spline, the number of the vertical ribs is the same as that of the ribs in each set, the vertical ribs surround the axial rod, and the spline is arranged on the axial rod or a pile foundation rod in a sleeving mode. The two splines are movably fixed to the first ends of the first set of ribs surrounding the axial rod and the second set of ribs surrounding the axial rod respectively, the second ends of the ribs are movably fixed to the vertical ribs, at least one spline slides, and the splines correspond to the original state of the variable-diameter reinforcement cage unit before and after sliding and the second diameter state of expanding the diameter after release respectively. The grids are wound on the peripheries of the vertical ribs of the reinforcement cage or/and the plurality of plane slope nets are uniformly distributed in the vertical ribs of the reinforcement cage. The grid plane of the folded and tightened grid net is in a horizontal plane, vertical plane or inclined plane form and is in an unused contraction state, an elastic device enabling a spline to slide is a power spring arranged on an axial rod in a sleeving mode, and a device releasing device for limiting opening of the reinforcement cage is a restraining rope, a restraining sleeve and a restraining stop pin.
一种网格加强式变径钢筋笼，包括一组竖筋、轴向杆、起码两组相同根数的若干筋条和起码一个花键，一组竖筋与每组若干筋条数相同并环绕轴向杆，花键套在轴向杆或桩基杆上，两个花键分别活络固定第一组与第二组环绕轴向杆的筋条的第一端，筋条的第二端活络固定竖筋上，起码一个花键滑动，花键在滑动前与滑动后分别对应变径钢筋笼单元的原始状态和释放后呈扩大直径的第二直径状态；网格绕制在钢筋笼的竖筋外周或/与多个平面斜面网均匀分布在钢筋笼的竖筋内；折叠收紧栅格网以网格平面以水平面、垂直面或斜面的形态是未使用收缩状态，使花键滑动的弹性装置为套在轴向杆上动力弹簧，限制钢筋笼打开的装置释放装置是约束绳、约束套、约束止销。
