AI Technical Summary
Existing bridge joint structures are unable to buffer the stress generated by thermal expansion and contraction or vehicle impacts, leading to cracking of concrete bridge decks, corrosion of reinforcing steel, and structural aging.
The system employs a buffer structure, comprising a lower support column, a first damper, an upper support column, a limiting plate, a connecting rod, and a slider. This buffer mechanism absorbs the energy from thermal expansion and contraction and vehicle impacts through the damper and buffer rod, preventing bridge tilting and cracking.
It effectively buffers the thermal expansion and contraction at bridge joints and the impact of vehicles, preventing damage to the bridge structure and maintaining the stability and service life of the bridge.
