Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a connection structure capable of reducing strength required for a steel concrete synthesis member and a reinforcement concrete member at a connection part in an oblique intersection direction crossing in an oblique direction with respect to an extending direction, and a box culvert connected with the connection structure and a tunnel.SOLUTION: The connection structure is a structure of a connection part S for connecting steel elements 50 and plural RC members 60 in a box extending direction BL, the connecting steel elements 50 being integrated by enclosing a concrete C with a flange steel plate 51 and a shear reinforcing steel plate 52. The connection part S is oriented in a rail extending direction RL crossing an extending direction. A distributing bar 63 disposed in the RC member 60 in an extending direction and a main reinforcement bar 62 perpendicular to the distributing bar 63 are inserted and fixed in the steel element 50.SELECTED DRAWING: Figure 2
【課題】延長方向に対して斜め方向に交差する斜交方向の接続部で鋼コンクリート合成部材及び鉄筋コンクリート部材が要する部材強度を低減できる接続構造、該接続構造で接続したボックスカルバート及びトンネルを提供することを目的とする。【解決手段】コンクリートCをフランジ鋼板51及びせん断補強鋼板52で囲って一体化した鋼製エレメント50と、RC部材60とがボックス延長方向BLに接続された接続部Sの構造であって、接続部Sが、延長方向に対して交差する軌道延長方向RLであり、RC部材60に設けられた延長方向の配力筋63及び配力筋63に直交する主鉄筋62を鋼製エレメント50の内部に挿入して定着した。【選択図】図2 |
