SLIDING MECHANISM OF BRIDGE SEISMIC RESISTANCE DEVICE
PROBLEM TO BE SOLVED: To provide a sliding mechanism of a bridge seismic resistance device, the mechanism that can respond to various installation variations in a limited space between a pier and an upper structure by making a compact configuration, and can reliably restrict the movement in the particular direction of the movable bearing even to the earthquake ground motion from any kind of directions.SOLUTION: A sliding mechanism of a bridge seismic resistance device 3 is provided for restricting an operation of a movable bearing in a bridge for supporting a bridge girder 6 through a movable bearing disposed to a pier 1. The bridge seismic resistance device includes a damper 4 stretching in the uniaxial direction, a connecting member 31 for connecting multiple dampers in series, a piece member 32 provided in the connecting member, and a guide rail 33 for slidably holding the piece member. Both ends of the multiple dampers connected in series are fixed in the pier or the bridge girder, and the guide rail is fixed in the right angle direction to the stretching uniaxial direction of the damper in the bridge girder or the pier.SELECTED DRAWING: Figure 1
【課題】コンパクトな構成とすることにより、橋脚と上部構造との間の限られたスペースに対して種々の設置バリエーションに対応でき、如何なる方向からの地震動に対しても、可動支承の特定方向の移動を確実に制限可能な橋梁耐震装置のスライド機構を提供する。【解決手段】橋脚1に配設された可動支承を介して橋桁6を支持する橋梁において、可動支承の動作を制限するための橋梁耐震装置3のスライド機構であって、橋梁耐震装置が、一軸方向に伸縮するダンパー4と、ダンパーを複数基直列に連結させるための接続部材31と、接続部材に設けられた駒部材32と、駒部材を摺動可能に保持するガイドレール33を備え、複数基直列に連結されたダンパーの両端が橋脚又は橋桁に固定され、ガイドレールが橋桁又は橋脚に、ダンパーの伸縮する一軸方向に対して直角方向に固定されている。【選択図】図1
