FLOOR SLAB REPLACEMENT STRUCTURE AND FLOOR SLAB REPLACEMENT METHOD
To provide a bridge structure and floor slab replacement method capable of easily and firmly connecting the lateral ribs of a steel plate floor to a main girder web and reliably transmitting a shear force in the bridge axial direction between the main girder and the steel plate floor.SOLUTION: A floor slab replacement structure includes: a concrete floor slab remaining part 21 which is left by removing a part other than the part provided on the upper surface side of a main girder upper flange 11b of a reinforced concrete floor slab 14; a concrete removal area R being 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 plate floor 30 arranged so as to cover the concrete floor slab remaining part 21 in the concrete removal area R. The steel plate floor 30 is arranged on the lower surface side of a deck plate 31 and one end surface or both end surfaces in the bridge width direction has a lateral rib 33 facing the web surface of a main girder web 11a of a nearest main girder 11. The end of the lateral rib 33 is rigidly coupled to the nearest main girder web 11a. The main girder 11 and the steel plate floor 30 are connected by a first shear force transmitting member 50.SELECTED DRAWING: Figure 4
【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コンクリート床版残置部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コンクリート除去領域Ｒと、コンクリート除去領域Ｒに、コンクリート床版残置部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とが第１せん断力伝達部材５０によって結合されている。【選択図】図４
