UPPER STRUCTURE, FLOOR SLAB MEMBER AND GIRDER MEMBER OF BRIDGE
PROBLEM TO BE SOLVED: To provide a stable joining of a floor slab to a cylindrical girder.SOLUTION: An upper structure of a bridge is provided with a cylindrical girder 10, and a plurality of first floor slabs 20 and second floor slabs 30 installed on the girder 10 and alternately arranged adjacent to each other in the direction of the central axis of the girder 10. A first key 11 and a second key 12 are projected on the top of a peripheral surface of the girder 10; a row of the first key 11 and a row of the second key 12 are arranged oppositely to each other with respect to a vertical plane passing the central axis of the girder 10; a columnar surface-like first concave surface 24 is formed on the undersurface of the first floor slab 20, and a columnar surface-like second concave surface 34 is formed on the undersurface of the second floor slab 30; the girder 10 is fitted to the concave surfaces 24, 34; a first key groove is formed on the first concave surface 24, and the second key groove is formed on the second concave surface 34; and the first key 11 is fitted to the first key groove, and the second key 12 is fitted to the second key groove.SELECTED DRAWING: Figure 2
【課題】円柱状の桁に床版を安定して接合できるようにする。【解決手段】橋梁の上部構造が、円柱状の桁１０と、桁１０上に設置され、桁１０の中心軸方向に隣接して交互に配列された複数の第一床版２０及び第二床版３０と、を備える。桁１０の周面の上部には第一キー１１及び第二キー１２が凸設され、第一キー１１の列と第二キー１２の列が桁１０の中心軸を通る鉛直面に関して互いに反対の位置に配され、第一床版２０の下面に円柱面型の第一凹面２４が形成され、第二床版３０の下面に円柱面型の第二凹面３４が形成され、桁１０が凹面２４，３４に嵌め込まれ、第一凹面２４に第一キー溝が形成され、第二凹面３４に第二キー溝が形成され、第一キー１１が第一キー溝に嵌められ、第二キー１２が第二キー溝に嵌められている。【選択図】図２
