AI Technical Summary

Technical Problem

The current bridge construction process faces difficulties in reinforcing the formwork of crash barriers, resulting in compromised construction quality. Furthermore, traditional reinforcement methods are inefficient and ineffective.

Method used

A crash barrier inner mold template fastening device is adopted. The device includes a support structure of threaded sleeve and high-strength screw. The length can be adjusted by threaded engagement. Combined with the angle design, it can adapt to different sizes and bridge deck structures. Q345 steel is used to improve tensile, shear and compressive strength.

Benefits of technology

It significantly improves construction efficiency, reduces labor costs, enhances construction quality, adapts to different environments and structures, reduces stress concentration and fatigue fracture risks, and enables rapid installation and efficient construction.
