Chain weft type variable-diameter reinforcement cage and anchor rod
A chain weft type variable-diameter reinforcement cage comprises a set of vertical ribs, an axial rod, at least one set 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 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 are in the second diameter state with the expanded diameter after being released respectively. Chains are arranged on the peripheries of the vertical ribs to serve as wefts of the periphery of the reinforcement cage, and the chains and the vertical ribs are provided with fixing points. An elastic device for sliding the spline and a device for limiting the opening of the reinforcement cage are arranged.
一种链条纬线式变径钢筋笼，包括一组竖筋、轴向杆、起码一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，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；竖筋外周设有链条作为钢筋笼外周的纬线，链条与竖筋设有固定点；设有使花键滑动的弹性装置，以及限制钢筋笼打开的装置。
