PROBLEM TO BE SOLVED: To readily join divided steel pipes.SOLUTION: A joint structure 46 includes a plurality of square steel pipes 21 lined up in a direction D2 orthogonal to a bridge axis, and a steel pipe connecting member 22 inserted into the plurality of square steel pipes 21 in the direction D2 orthogonal to the bridge axis, the square steel pipe 21 connecting ends 30 abutted to each other of a pair of dividing steel pipes 27 lined up next to each other in a bridge axis direction D1, of a bridge deck slab unit 20 divided in the bridge axis direction D1 by a plurality of the dividing steel pipes 27. The ends 30 are lined up along the direction D2 orthogonal to the bridge axis next to an intermediate part in the bridge axis direction D1 of another steel pipe lined up next to the pair of dividing steel pipes 27 in the direction D2 orthogonal to the bridge axis, and the steel pipe connecting member 22 is inserted into the ends 30 through the intermediate part in the bridge axis direction D1 of the other steel pipe.SELECTED DRAWING: Figure 2 【課題】分割鋼管を簡便に接合する。【解決手段】橋軸直角方向Ｄ２に並べられた複数本の角形鋼管２１と、複数本の角形鋼管２１に橋軸直角方向Ｄ２に挿通された鋼管連結材２２と、を備え、角形鋼管２１は、橋軸方向Ｄ１に複数本の分割鋼管２７に分割された橋床版ユニット２０において、橋軸方向Ｄ１に隣り合う一対の分割鋼管２７のうち、互いに突き合わされた両端部３０を接合する鋼管の継手構造４６であって、両端部３０は、一対の分割鋼管２７と橋軸直角方向Ｄ２に隣り合う他の鋼管における橋軸方向Ｄ１の中間部と、橋軸直角方向Ｄ２に並び合い、鋼管連結材２２は、前記他の鋼管における橋軸方向Ｄ１の中間部を通して両端部３０に挿通されている。【選択図】図２
