JOINING STRUCTURE AND ERECTION METHOD OF EARTH RETAINING H-SHAPED STEEL PILE
PROBLEM TO BE SOLVED: To provide a joining structure of an earth retaining H-shaped steel pile, excellent in strength and stress transmission, while minimally restraining processing in a joining part, on the assumption of using marketed H-shaped steel and steel plate standardized in the principle.SOLUTION: On an earth retaining back face side flange, a filler plate 11 composed of a steel plate corresponding to a plate thickness difference with a flange 1a of a lower steel material 1, is spliced on a surface of a flange 2a of an upper steel material 2, and is joined by a bolt via a splice plate 31. On the earth retaining inside, an additional plate 3 is provided in an upper part of the lower steel material, and the additional plate provided in the lower steel material is butted against a flange 2b of the upper steel material, and a filler plate 12 is spliced when necessary, and is joined by the bolt via a splice plate 32. On mutual webs, when joining by butting the web 2c of the upper steel material against the web 1c of the lower steel material, a third filler plate 13 is spliced when necessary, and is joined by the bolt via a splice plate 33.
【課題】原則的に規格化された市販のＨ形鋼や鋼板を用いることを前提とした上で、接合部における加工を最小限に抑えつつ、強度および応力の伝達に優れた山留めＨ形鋼杭の接合構造を提供する。【解決手段】山留め背面側のフランジについては、上部鋼材２のフランジ２ａの表面に下部鋼材１のフランジ１ａとの板厚差に応じた鋼板からなるフィラープレート１１を添わせ、添接板３１を介してボルト接合する。山留め内側については、下部鋼材の上部に追加プレート３を設け、上部鋼材のフランジ２ｂと下部鋼材に設けた追加プレートを突き合わせ、必要に応じフィラープレート１２を添わせ、添接板３２を介してボルト接合する。ウェブどうしについては、上部鋼材のウェブ２ｃを下部鋼材のウェブ１ｃに突き合わせて接合するにあたり、必要に応じ第３のフィラープレート１３を添わせ、添接板３３を介してボルト接合する。【選択図】図１
