Title:
機能分離型衝撃吸収装置及び機能分離型衝撃吸収装置を備えた橋梁
Document Type and Number:
Japanese Patent JP7017879
Kind Code:
B2
Abstract:
To provide a function separation type shock absorber and a bridge provided with a function separation type shock absorber having high deformation capacity and energy absorption capacity in both tension and compression directions and being installed mainly as a bridge fall preventing member between an end of a bridge girder and an abutment supporting the end of the girder.SOLUTION: A joint part 5 and a joint part 6 are attached at both ends in the bridge axial direction. First and second deformation core materials 7A and 7B and a displacement core material 8 are disposed adjacently to each other in the bridge axial direction on the same material axis between the joint part 5 and the joint part 6. A plurality of buckling restraining materials 9 are installed on the outer side of a direction perpendicular to the axis of the first and second deformation core materials 7A and 7B and the displacement core material 8. The first and second deformation core materials 7A and 7B are installed so as to be elastically or plastically deformed by receiving compression and tensile loads in the bridge axial direction. The displacement core material 8 receives compression and tensile loads in the bridge axial direction, and is installed so as to be displaced in the bridge axial direction without resistance in a state in which the connection with the joint part 5 is disconnected.SELECTED DRAWING: Figure 1
