Umbrella-shaped variable-diameter reinforcement cage, umbrella-shaped cage core capsule and anchor rod
The invention discloses an umbrella-shaped variable-diameter reinforcement cage. The umbrella-shaped variable-diameter reinforcement cage comprises a group of vertical ribs, an axial rod, at least two groups of ribs with the same number and at least one sliding spline, wherein a fixed spline is located at the bottom end of the axial rod (also used as a bearing plate), the vertical ribs are the same as the ribs in each group in number and surround the axial rod, one end of each vertical rib is open, the other end of each vertical rib is fixed on a hinge pin of the fixed spline in a loose mode, the sliding spline and the fixed spline are both arranged on the axial rod or a pile foundation rod in a sleeve mode, a movable spline fixes a set of ribs surrounding the axial rod, namely the first ends of supporting ribs, the second ends of the set of ribs are movably fixed to vertical ribs (inclined ribs), before and after sliding, the movable spline corresponds to an original state of a variable-diameter reinforcement cage unit and a second diameter state of expanding the diameter after release respectively, the vertical ribs serve as umbrella ribs, the ribs serve as the supporting ribs for supporting the umbrella ribs, furthermore, according to the the umbrella-shaped variable-diameter reinforcement cage, the umbrella-shaped cage core capsule and the anchor rod, two sliding splines or above and the two groups of corresponding supporting ribs or above can be arranged.
一种伞形变径钢筋笼，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滑动花键，一个固定花键位于轴向杆底端(也作为承压板)，一组竖筋与每组若干筋条数相同并环绕轴向杆，竖筋一端开放，另一端活络固定在固定花键的销轴，活动与固定花键均套在轴向杆或桩基杆上，活络花键固定一组环绕轴向杆的筋条即撑骨的第一端，一组筋条的第二端活络固定竖筋(斜筋)上，活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；竖筋作为伞骨，筋条作为撑住伞骨的撑骨。进一步，本发明可以设有二个以上滑动花键和对应的二组以上的撑骨。
