BRIDGE STRUCTURE AND FLOOR SLAB REPLACING METHOD
To provide a bridge structure and a floor slab replacing method capable of easily and firmly connecting a horizontal rib of a steel floor slab to a main girder web, and reliably transmitting a shear force between the main girder and the steel floor slab in the direction of a bridge axis.SOLUTION: The bridge structure includes: remaining reinforced concrete 21 that is left by removing a part other than a part provided on an upper surface side of a main girder upper flange 11b of a reinforced concrete floor slab 14; a removal part 20 formed by removing the part other than the part provided on the upper surface side of the main girder upper flange 11b; and a steel floor slab 30 arranged on the removal section 20 to cover the remaining reinforced concrete 21. The steel floor slab 30 includes a lateral rib 33 disposed on a lower surface side of a deck plate 31 and having one end surface or both end surfaces in the bridge width direction facing a web surface of a main girder web 11a of a nearest main girder 11. An end of the lateral rib 33 is rigidly connected to the nearest main girder web 11a, and the main girder 11 and the steel floor slab 30 are connected by a shearing force transmission member 50.SELECTED DRAWING: Figure 17
【課題】鋼床版の横リブを容易かつ強固に主桁ウエブに結合できるともに、主桁と鋼床版との間で橋軸方向にせん断力を確実に伝達することができる橋梁の構造および床版取替え方法を提供する。【解決手段】鉄筋コンクリート床版１４の、主桁上フランジ１１ｂの上面側に設けられている部分以外を除去して残置されてなる残置鉄筋コンクリート２１と、主桁上フランジ１１ｂの上面側に設けられている部分以外を除去してなる除去部２０と、除去部２０に、残置鉄筋コンクリート２１に被せるように配設された鋼床版３０とを備え、鋼床版３０は、デッキプレート３１の下面側に配設され、橋幅方向の一端面または両端面が直近の主桁１１の主桁ウエブ１１ａのウエブ面と対向する横リブ３３を有し、横リブ３３の端部が直近の主桁ウエブ１１ａに剛結合され、主桁１１と鋼床版３０とがせん断力伝達部材５０によって結合されている。【選択図】図１７
