To provide a temporary bridge unit capable of withstanding a necessary and sufficient load as a temporary bridge in times of a disaster such as the passage of a person or a vehicle, and is designed to be suitable for erection by manual labor.SOLUTION: A temporary bridge unit is provided with a plurality of main girder structures 2 extending in the bridge axis direction and arranged at predetermined intervals in the bridge axis orthogonal direction, and a connecting material 6 for connecting the plurality of main girder structures 2 in the bridge axis orthogonal direction; the main girder structure 2 has a sleeper 21, a pair of columns 3 arranged at both ends in the bridge axial direction and provided with a sleeper receiver 33 at an upper end, one or a plurality of connection materials 4 arranged between the pair of columns 3, 3 and provided with a sleeper receiver 43 at an upper end, and a plurality of beam frame materials 5 laid between the column 3 and the connection material 4 or between the connection materials 4, 4. The beam frame member 5 is formed in a frame shape by integrating a plurality of horizontal members 52, 53 arranged at intervals in the vertical direction and connecting members 55, 561, 562 for connecting the horizontal members 52, 53 to each other.SELECTED DRAWING: Figure 1
【課題】人や車両の通行等、災害時等の仮設橋として必要十分な荷重に耐えることが可能であって、人力作業での架設に適する工夫がなされた仮設橋ユニットを提供する。【解決手段】橋軸方向に延在すると共に橋軸直交方向に所定の間隔をあけて配置される複数の主桁構造体２と、複数の主桁構造体２を橋軸直交方向に連結する繋材６と、を備え、主桁構造体２は、大引２１と、橋軸方向の両端に配置され上端に大引受３３が設けられた一対の支柱３と、一対の支柱３，３間に配置され上端に大引受４３が設けられた１又は複数の連結材４と、支柱３と連結材４との間又は連結材４，４間に架け渡される複数の梁枠材５と、を有し、梁枠材５は、上下方向に間隔をあけて配置された複数の横材５２，５３と、横材５２，５３どうしを連結する連結材５５，５６１，５６２とが一体化されてフレーム状に構成されたものである。【選択図】図１
