Embodiment Construction

[0229] The variable-diameter steel cage or fiber cage of the elastic memory element consists of latitudinal or radial elastic memory elements or is connected with several radial latitudinal elastic memory elements surrounding the main reinforcement, and the latitudinal elastic memory element itself is connected to the main reinforcement through connecting rods , the latitudinal elastic memory element is connected to the radial elastic memory element; the elastic memory element is rod-shaped, sheet or mesh-shaped elastic memory element;

[0230] The elastic element is a radial elastic memory rod, and the radial elastic memory rod is a section of arcs or concentric ellipses in the shape of several ellipses. The diameters of the concentric ellipses are all main ribs. The rods or concentric ellipses become elastic releasable elements after being bound elastically by the restraining ropes to release the cage. Weft elastic memory elements include, stirrups, stirrup nets, chain nets,...

Abstract

An elastic memory variable-diameter reinforcement cage or fiber cage comprises a weft elastic memory element, a radial elastic memory element or a weft elastic memory element which are connected with a plurality of weft elastic memory elements surrounding the radial direction of a main rib, and the weft elastic memory element or the radial elastic memory element is connected to the main rib or connected to the main rib through a connecting rod; or the weft elastic memory elements are connected with the radial elastic memory elements; the elastic memory element is a rod-shaped, sheet-shaped or net-shaped elastic memory element; the weft elastic memory elements comprise stirrups, stirrup nets and chain nets. The elastic element is a radial elastic memory rod, and the radial elastic memory rod is a section of arc or concentric ellipse of a plurality of ellipses.

Description

technical field [0001] The invention relates to an elastic memory variable diameter cage (enlarged head cage), including a steel reinforcement cage or a fiber cage and a structure used for an anchor rod or a pile, especially a variable diameter fiber cage, an expanded body anchor rod, and a pressure pile for use in The technical category of anti-floating foundation pit support for building basements, slope support, and piles for reinforcement and compression. Background technique [0002] Existing variable diameter (enlarged head cage) steel cages or fiber cages and structures for anchor rods or piles have been used in many ways, but there is one part that is indispensable: the release device (typically a power spring release device) ), such as CN2017103161244, a variable-diameter reinforcement cage for anchor rods or pile foundations and application patents, refers to variable-diameter reinforcement cages for anchor rods or pile foundations, including main reinforcement, se...
