Weft disconnection type variable-diameter fiber cage and anchor rod thereof

Abstract

The invention discloses a weft disconnection type variable-diameter fiber cage which comprises an axial rod, namely a main rib, a plurality of vertical ribs, two groups of same movable connecting ribs, a first ring-shaped fixer, a second ring-shaped fixer and a release mechanism of a variable-diameter reinforcement cage, wherein the number of the movable connecting ribs is the same as that of the vertical ribs; the plurality of vertical ribs surround the main rib, the first group of a plurality of movable connecting ribs are respectively connected with the upper ends of the plurality of vertical ribs and a plurality of fixed joints on the circumference of the first ring-shaped fixer, a second group of a plurality of movable connecting ribs are respectively connected with the lower ends of the plurality of vertical ribs and a plurality of fixed joints on the circumference of the second ring-shaped fixer, and the plurality of vertical ribs are warps. The cage is characterized in that short wefts are uniformly fixed on the vertical ribs, when the variable-diameter reinforcement cage shrinks, the short wefts of the same latitude on the adjacent vertical ribs have overlapping areas, and the releasing mechanism enables the overlapping areas of the short wefts to be reduced or disappear when the variable-diameter reinforcement cage is released; and the connected short wefts at the same latitude on the adjacent vertical ribs are provided with fixing mechanisms.

Description

technical field [0001] The invention relates to a variable diameter (enlarged head cage) fiber cage and a structure used for anchor rods or piles, especially a weft disconnection type used for variable diameter fiber cage expansion anchor rods and pressure piles, used for building basement anti-corrosion The technical category of floating foundation pit support, slope support, and reinforcement and compression piles. Background technique [0002] Variable-diameter reinforcement cages and application patents have been used in many ways, such as CN2017103161244 A variable-diameter reinforcement cage for anchor rods or pile foundations and application patents, which refers to variable-diameter reinforcement cages for anchor rods or pile foundations, including main reinforcement, several vertical reinforcement, At least two ring-shaped anchors and several groups of ribs corresponding to the ring-shaped anchors, the ring-shaped anchors are all sleeved on the main reinforcement or...

AI Technical Summary

Problems solved by technology

The fiber cage of the variable diameter fiber cage enlarged head anchor pile with weft disconnection and the release structure of the enlarged variable diameter are used to make the variable diameter fiber cage work, which can be applied to all expanded body anchor pile technologies and overcome the disadvantages of plain slurry enlarged head Insufficient anchorage bearing capacity and poor integrity
