EMERGENCY TEMPORARY BRIDGE
To provide a temporary bridge that can be erected urgently to save lives, transport goods, and the like, in the event of a flood.SOLUTION: Floor slab panels 21, in which multiple pieces are connected in a bridge axis direction so that a connection part can be bent in a direction perpendicular to the bridge axis, are installed on an origin side bank 1 in a spirally wound state. The floor slab panels 21 are sequentially unwound and rotated on a leading girder 5 material previously installed between the origin side bank 1 and an arrival side bank 2, thereby developing and extending a floor slab 20 connected between the origin side bank 1 and the arrival side bank 2. Thus, a temporary bridge 10 is formed in which both ends of the erected floor slab 20 are supported by fulcrum blocks 14, and the floor slab 20 forms an arch shape due to tension introduced into a closing cable 12 stretched below the floor slab 20.SELECTED DRAWING: Figure 1
【課題】水害発生時に、人命救助、物資搬送等のために緊急に架設可能な仮設橋を提供する。【解決手段】 連結部が橋軸直角方向に折り曲げ可能に複数枚が橋軸方向に連結された床版パネル２１が、渦巻き状に巻かれた状態で起点側岸１に設置される。起点側岸１と到達側岸２との間にあらかじめ架設された先行桁部５材上を、床版パネル２１が順次巻き解かれて回動することで展開、伸長して起点側岸１と到達側岸２との間に連結された床版２０が架設される。架設された床版２０の両端が支点ブロック１４で支持されるとともに、床版２０の下方に張設された閉合ケーブル１２に導入された緊張力により、床版２０がアーチ形状をなす仮設橋１０となる。【選択図】 図１
