AI Technical Summary
Existing highway bridge reinforcement devices are prone to loosening the connection with the bridge body after long-term use, which may be affected by vibration, temperature changes, material aging and natural environment, resulting in reduced reinforcement effect and reduced bridge safety.
A highway bridge reinforcement device is designed, including main beam, base, buffer groove, buffer rod, buffer block, connecting rod, reinforcement plate, reinforcement bolt and spring structure. Through the reset elastic force of the first and second spring structures on both sides of the buffer block, the left and right sliding of the bridge main beam plays a role in buffering and strengthening, increasing the stability of the connection.
Compared with the traditional direct fixed connection method, the device is more flexible, effectively avoiding loosening at the connection, improving the reinforcement effect and bridge safety. At the same time, the buffer block position is recorded through scale identification, which facilitates the subsequent judgment of the bridge displacement and formulates a more accurate reinforcement plan.
