PROBLEM TO BE SOLVED: To provide the vibration insulation of a high bridge for devising a solution plan suitable for reducing a vibration number and avoiding temperature stress by specifying the vibration number being a factor on the basis of analysis. SOLUTION: In the high bridge continuously constituting a unit high bridge 50 having a cantilever 1 on the end in a frame structure between a plurality of spans while holding a prescribed interval, the thickness of the end 2 of the cantilever 1 is increased, a support body 4 enabling movement in the adjacent direction between the beam end 2 and a common holding column 3 is arranged, impact force of a passing train or a vehicle and vibration generated on the cantilever part between the adjacent high bridges are reduced, and temperature stress generated on the unit high bridge is avoided by maintaining gap. |
