AI Technical Summary

Technical Problem

The current technology of measuring the steel bars of the crash barrier with a tape measure is inefficient and makes it difficult to ensure the installation quality of the top bent steel bars and vertical steel bars, which affects the service durability of the crash barrier.

Method used

Design a rapid positioning and detection device, including a top horizontal support, a left vertical rod, a bent rebar formwork, a right vertical rod, and a vertical rebar formwork. By having these components abut against the top bent and vertical rebars of the crash barrier, detect whether their curvature and linearity meet the design specifications.

Benefits of technology

It enables rapid and accurate detection of the installation quality of the steel reinforcement in the crash barrier, improves construction efficiency and control of the steel reinforcement protective layer thickness, and ensures the durability and safety of the crash barrier.

Abstract

This application discloses a rapid positioning and testing device for the reinforcing bars of a crash barrier, comprising: a top horizontal support; a left vertical rod connected to the bottom of the top horizontal support; a bent-up reinforcing bar formwork set at the bottom of the top horizontal support, adapted to the top bent-up reinforcing bars of the crash barrier; a right vertical rod connected to the bent-up reinforcing bar formwork; and a vertical reinforcing bar formwork connected to the right vertical rod, adapted to the vertical reinforcing bars of the crash barrier, for detecting the linearity and length of the vertical reinforcing bars. During the inspection of the crash barrier reinforcing bars, the operator holds the left vertical rod to place the top horizontal support onto the horizontal section of the top bent-up reinforcing bar, and aligns the bent-up reinforcing bar formwork with the curved section of the top bent-up reinforcing bar, checking whether the curvature of the curved section of the top bent-up reinforcing bar conforms to the drawings and specifications. The vertical reinforcing bar formwork is then used to check whether the linearity and length of the vertical reinforcing bars conform to the drawings and specifications.
