BRIDGE FALL PREVENTION METHOD FOR EXISTING BRIDGE GIRDER EXPOSED TO SEISMIC AND TSUNAMI FORCE
PROBLEM TO BE SOLVED: To provide a bridge fall prevention method for an existing bridge girder that considers for a structural system of bridge pier and girder exposed to seismic and tsunami force.SOLUTION: In a bridge fall prevention method for an existing bridge girder exposed to seismic and tsunami force: a reinforcing bar 3 is installed by drilling a hole through existing bridge girders B on right and left to suit a diameter of the reinforcing bar, and inserting and fixing the reinforcing bar 3 into the hole; a reinforcing bar is installed by drilling a hole through the bridge pier A for a receiving beam 2 to suit a diameter of the reinforcing bar, and inserting and fixing the reinforcing bar into the hole for the receiving beam 2; a concrete mold is placed, and a reinforcing bar is arranged; a bridge fall prevention device 1 is installed, and concrete is cast; the receiving beam 2 is installed by drilling a hole beforehand through the bridge fall prevention device 1 for inserting the reinforcing bar, and a cushioning material 4 is installed between the bridge fall prevention device 1 and both bridge girders B.SELECTED DRAWING: Figure 1
【課題】 地震及び津波作用を受ける、橋脚と橋桁の構造系を考慮した既設橋桁の落橋防止工法を提供する。【解決手段】 地震及び津波作用を受ける、既設橋桁の落橋防止工法において、左右の既設橋桁Ｂに鉄筋径に応じた孔を削孔し、この削孔に鉄筋３を挿入し、接着することにより鉄筋３を設置し、橋脚Ａに受け梁２用の孔を鉄筋径に応じて削孔し、この受け梁２用の孔に鉄筋を挿入し、接着することにより鉄筋を設置し、型枠を設置し、配筋、落橋防止装置１の据え付けを行い、コンクリートを打設するとともに、前記落橋防止装置１には、事前に鉄筋挿入用の孔を設けて受け梁２を設置し、落橋防止装置１と両橋桁Ｂの間に衝撃緩衝材４を設置する。【選択図】 図１
