TENDON ANCHORING STRUCTURE
To provide anchoring structure or the like for a tendon capable of avoiding concentration of pressure caused by tension of the tendon and preventing occurrence of a crack or the like.SOLUTION: The anchoring structure comprises: a reinforcing plate 3 placed on the lower surface of an underfloor slab 12 of a box girder bridge through which a vertical tendon 4a passes and made of UHPFRC through which the end of the vertical tendon 4a is inserted; and a fastener 6 which is placed on the lower surface of the reinforcing plate 3 and fixes the end of the vertical tendon 4a. The pressure resulting from the tensioning of the vertical tendon 4a is dispersed by the high-strength reinforcing plate 3 and transmitted to the underfloor slab 12 in a planar manner.SELECTED DRAWING: Figure 3
【課題】緊張材の緊張に伴う圧力の集中を避け、ひび割れ等の発生を防止できる緊張材の定着構造等を提供する。【解決手段】定着構造は、鉛直緊張材４ａの通される箱桁橋の下床版１２の下面に配置され、鉛直緊張材４ａの端部が挿通されるUHPFRC製の補強板３と、補強板３の下面に配置され、鉛直緊張材４ａの端部を定着する定着具６と、を有し、鉛直緊張材４ａの緊張に伴う圧力が高強度の補強板３により分散して面的に下床版１２に伝達される。【選択図】図３
