PROBLEM TO BE SOLVED: To provide a function separating type supporting device eliminating problems of noise and vibration and at the same time functioning as a moving limiting device used also as a bridge fall preventing device. SOLUTION: This function separating type bridge supporting device in which a lateral beam 2 for connecting main beams 1 and 1 is installed between upper structures 1 and 2 built by concrete and a lower structure 3 comprises vertical supports 9 and 9 which are installed between the main beams 1 and 1 and the lower structure 3 and support vertical load of the upper structures 1 and 2, a supporting base 25 installed on the lower structure 3 between the main beams 1 and 1, elastic bodies 28 and 28 which are installed between each side surface along bridge shaft directions of the lateral beam 2 and the supporting base 25 and support horizontal load of the upper structures 1 and 2, and a stopper 30 in which a lower side is fixed to the supporting base 25, an upper side is inserted into an oblong hole 34 formed in the bridge shaft direction on a lower surface of the lateral beam 2 and moving in the bridge shaft direction is allowed in a length range of the oblong hole 34. |
