Document Type and Number:
Japanese Patent JP3640251
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a bridge reinforcing structure for always imparting constant pulling-up force to a floorslab or a bridge beam of a bridge, reducing stress by a live load applied to the floorslab and the bridge beam such as a traveling vehicle, and reducing stress generated by a dead load of applying no these live loads, that is, a dead load by dead weight of the bridge itself.
SOLUTION: An installing beam 8 between left-right bridge piers extending in the bridge lengthwise direction is installed in left-right outside areas of the bridge 6 between the bridge piers 4. A sleeper material 7 for receiving a load of the bridge 6 is horizontally arranged for extending in the bridge width direction along an under surface of the other bridge 6. Both ends of the sleeper material 7 are projected in the left-right outside areas of the bridge 6.
