Diameter-variable reinforcement cage

CHEN YANGYANG

The invention discloses a variable-diameter reinforcement cage, and relates to the technical field of rock-soil anchoring equipment, the variable-diameter reinforcement cage comprises a base and a plurality of vertical steel bars arranged in a circle, an anchor rod is located in the circle formed by the vertical steel bars, the base is provided with a sliding hole for the anchor rod to slide, the anchor rod is fixedly connected with a mounting plate, and the mounting plate is fixedly connected with the base. The mounting plate is located above the base, a first connecting rod is arranged between the mounting plate and each vertical reinforcing steel bar, one end of each first connecting rod is hinged to the corresponding vertical reinforcing steel bar, the other end of each first connecting rod is hinged to the mounting plate, the top end of each first connecting rod inclines towards the side close to an anchor rod, and the top end of each first connecting rod inclines towards the side close to the anchor rod. A second connecting rod is installed between the base and each vertical steel bar, one end of the second connecting rod is hinged to the corresponding vertical steel bar, the other end of the second connecting rod is hinged to the base, and the top end of the second connecting rod inclines towards the side away from the anchor rod. The method has the effect that the possibility that the reinforcement cage is unfolded in the anchoring holes is improved.
