Improving the seismic resistance of bridges and early detection of bolt loosening.
In terms of seismic resistance of bridges, proper management of bolts is extremely important. External forces such as earthquakes can cause bolts to loosen, leading to a risk of reduced structural strength and collapse. Particularly in bridges exposed to wind and rain for long periods, corrosion and fatigue of bolts can progress easily, making regular inspections and axial force management essential. The UI-27AF ensures the safety of bridges by early detection of abnormalities in bolts through high-precision axial force measurement. 【Usage Scenarios】 - Measurement of bolt axial force in major structural components of bridges (main girders, deck slabs, etc.) - Measurement of bolt axial force during regular inspections - Management of bolt tightening in seismic reinforcement work 【Benefits of Implementation】 - Prevents damage to bridges caused by loosening bolts - Maintains and improves the seismic performance of bridges - Reduces maintenance costs
