UNDERSTRUCTURE OF BRIDGE
PROBLEM TO BE SOLVED: To effectively use as much as possible an internal space of a post beam bridge frame.SOLUTION: In an understructure 1 of a bridge according to the present invention, posts 3 are respectively raised so as to mutually face footings 2, 2, and a beam 4 is bridged on a top part of the pair of posts 3, 3, thus, the posts 3, 3 and the beam 4 constitute a rahmen bridge frame 5 as a post beam bridge frame. The beam 4 is provided with protrusion parts 6, 6 as a damper fitting part in such a manner as being parallel to a frame surface of the rahmen bridge frame 5 and extending toward the outside of the rahmen bridge frame, and between the protrusion part 6 and the post 3, the friction damper 7 is diagonally arranged respectively for bracing support. The protrusion part 6 may be configured as a part of the beam 4 that protrudes from an outer side surface of the post 3.SELECTED DRAWING: Figure 1
【課題】柱梁架構の内部空間を可能な限り有効利用する。【解決手段】本発明に係る橋梁の下部構造１は、フーチング２，２に互いに対向するように柱３をそれぞれ立設するとともに、これら一対の柱３，３の頂部に梁４を架け渡して構成してあり、柱３，３及び梁４は、柱梁架構としてのラーメン架構５を構成する。梁４には、ラーメン架構５の構面に平行にかつ該ラーメン架構の外側にそれぞれ延びるようにダンパー取付部としての張出し部６，６を設けてあり、張出し部６と柱３との間には、摩擦ダンパー７を頬杖状にそれぞれ斜め配置してある。張出し部６は、柱３の外側側面から突出するように梁４の一部として構成すればよい。【選択図】 図１
