Description

Reinforced (rfd) rebar retractor structure is connected to new and old wall body

Technical Field

The utility model relates to the technical field of steel bar drag hooks, in particular to a steel bar drag hook structure for connecting and reinforcing new and old walls.

Background

A drag hook reinforcement, also called a single-limb hoop, is a hoop reinforcement with one number of the hoop reinforcements in the height (horizontal) direction in the same section of a finger beam (or a column), is similar to an S hook, and a general small-section beam has smaller width and correspondingly generates smaller shearing force in the beam.

Traditional drag hook muscle can not extend and shorten, can only be suitable for with the reinforcement between the specific new and old wall, simultaneously, traditional drag hook muscle is difficult not enough to the reinforcement degree of wall, in order to further improve the dynamics of strengthening of drag hook muscle, we have designed a new and old wall connection reinforced (rfd) rebar drag hook structure.
