PROBLEM TO BE SOLVED: To provide a function separating type supporting device for a bridge of a slide type elastic supporting device for supporting a load of a suitable upper structure for the bridge, etc., for new construction and a horizontal force and lift force elastic resistance device. SOLUTION: A lower supporting member 2 and an elastic supporting body 5 compose a slide type elastic supporting device 30 for supporting a load. So, lower and upper steel members 9, 10 of the supporting body 5 are fitted into a shear deformation restraining wall 4 without a horizontal movement. A level of an upper surface of the upper steel member 10 is provided higher than that of the restraining wall 4. An upper structure 22 is slidably supported through a slide-supporting member provided on an upper part of the upper steel member 10. A lower part of a horizontal force and lift force elastic resistance device 46 having steel members 50, 53 at a top and bottom of both end parts of an elastic layer 51 is fixed on an upper part of a lower structure 1. An end part of a main beam 47 and the horizontal force and lift force elastic resistance device 46 adjacent to each other are connected with a cross beam 49 provided on an upper part of the resistance device 46. |
