EMERGENCY TEMPORARY BRIDGE AND CONSTRUCTION METHOD THEREOF
To provide a bridge that can be urgently constructed for making available to lifesaving, resource transportation, etc. when a flood disaster occurs due to a typhoon, etc.SOLUTION: A emergency temporary bridge has truss main members 25 and floor slabs 22 where both sides are held by bottom chords 21 of the truss main members 25, and comprises multiple truss units 20 that constitute truss frames T by being connected across span length of a bridge, air tubes 11 extending so as to connect between upper end vertices of the truss units 20, and fulcrum members 14 and 15 of the bridge. A temporary bridge 10 supported with the fulcrum members 14 and 15 is formed by gradually revolving in association with expansion and extension of the air tubes 11 and extending and elongating the truss frames T, from the state in which it is revolved and put together around connection points of ends of the bottom chords 21 and it is placed at a construction origin position.SELECTED DRAWING: Figure 1
【課題】 台風等による水害発生時に、人命救助、物資搬送等に供するために緊急に架設できる橋梁を提供する。【解決手段】 トラス主構材２５と、トラス主構材２５の下弦材２１に両側辺が保持された床版２２とを有し、橋梁の支間長にわたり複数基を連結してトラス架構Ｔを構成するトラスユニット２０を、トラスユニット２０の各上端頂点間を連結するように延設されたエアチューブ１１と橋梁の支点部材１４，１５とを備え、下弦材２１端の連結点回りに回動させてまとめられて架設起点位置に設置された状態から、エアチューブ１１の膨張、展開に伴って順次回動してトラス架構Ｔが展開、伸長し、支点部材１４，１５で支持された仮設橋１０となる。【選択図】 図１
