CONNECTION STRUCTURE FOR BRIDGE USING REINFORCED CONCRETE FLOOR SLAB, AND CONNECTION METHOD FOR EXISTING BRIDGE USING REINFORCED CONCRETE FLOOR SLAB
PROBLEM TO BE SOLVED: To provide a connection structure for a bridge using a reinforced concrete floor slab and a connection method for an existing bridge using the reinforced concrete floor slab that may be installed simply and readily and offers sufficient load bearing ability.SOLUTION: A floor slab connecting part 10 is used with an existing concrete floor slab bridge 100 that uses a reinforced concrete floor slab 100a, and includes: a connecting upper reinforcing bar 50 that connects upper reinforcing bars 5a on both sides, so as to cover a work section X between separated edge parts of the reinforced concrete floor slabs 100a; a fixing part 21 on both ends connected to upper flanges 2a that face each other over a joint gap between separated edge parts of steel main girders 2 and an upper flange 3a of an end cross girder 3; a formed steel plate 20 disposed to cover the work section X and having a raised part 22 raised in a height direction above the fixing part 21; and a concrete part 60 cast on the work section X.SELECTED DRAWING: Figure 1
【課題】単純で簡単に施工できるとともに、十分な耐力を有する鉄筋コンクリート床版を用いた橋梁における連結構造及び鉄筋コンクリート床版を用いた既設橋梁における連結工法を提供することを目的とする。【解決手段】鉄筋コンクリート床版１００ａを用いた既設コンクリート床版橋１００における床版連結部１０として、鉄筋コンクリート床版１００ａの離間する端部同士の間の施工箇所Ｘを跨ぐように両側の上鉄筋５ａと連結した連結上鉄筋５０と、鋼製主桁２の離間する端部同士の間の遊間において対向する上フランジ２ａ及び端横桁３の上フランジ３ａに接続する両端の固定部２１と、施工箇所Ｘを跨ぐように配置し、固定部２１に対して、高さ方向に嵩上げされた嵩上げ部２２とを備えた成形鋼板２０と、施工箇所Ｘに打設したコンクリート部６０とで構成した。【選択図】図１
