STEP OVERCOMING BRIDGE
PROBLEM TO BE SOLVED: To provide a step overcoming bridge that facilitates assembly/disassembly of multiple bridge forming bodies on the site where steps or cracks are caused in a road, and the connection can be strengthened in an assembled condition.SOLUTION: A step overcoming bridge is bridged on the steps caused in a road, while connecting multiple bridge forming bodies 2A, 2B, 2C where tread members 4 are disposed between girder members 3 of substantially C-shaped cross sections through connecting members 7. In the step overcoming bridge, through-holes 9 are provided in the vertical piece in the longitudinal end of the girder member, and engaging holes 6 capable of being matched with the through-holes are provided in the connecting members each inserted between a horizontal upper piece and a horizontally lower piece of the girder member. While the connecting members are inserted between the horizontal upper piece and the horizontally lower piece of the adjacent bridge forming body, locking pins 5 are penetrated in through-holes and engaging holes to connect the bridge forming bodies, and the locking pins are extracted from the through-holes and the engaging holes to form the bridge forming bodies in a disassembly manner.SELECTED DRAWING: Figure 1
【課題】道路に段差や亀裂等が生じた現場において、複数のブリッジ形成体の組立・分離を容易にすることができ、組立状態において連結を強固にすることができる段差乗り越え用ブリッジを提供すること。【解決手段】、断面略Ｃ字状の桁部材３間に踏板部材４が配置された複数のブリッジ形成体２Ａ，２Ｂ，２Ｃを、連結部材７を介して連結した状態で、道路に生じた段差に掛け渡される段差乗り越え用ブリッジにおいて、桁部材の長手方向の端部における垂直片に貫通孔９を設け、桁部材の水平上片と水平下片間に挿入される連結部材に、貫通孔と合致可能な係合孔６を設ける。隣接するブリッジ形成体の水平上片と水平下片間に連結部材が挿入された状態で、係止ピン５を貫通孔及び係合孔に貫通してブリッジ形成体を連結し、係止ピンを貫通孔及び係合孔から抜き取って、ブリッジ形成体を分離可能に形成する。【選択図】図１
