FLOOR SLAB STRUCTURE
PROBLEM TO BE SOLVED: To provide a floor slab structure capable of making a crack hard to be caused by upward provided pavement, in the floor slab structure of not connecting a joint part in the bridge axial direction of a floor slab panel adjacent in the bridge axial direction.SOLUTION: In a floor slab structure 1, sandwich lightweight floor slab panels 10A and 10B are laid in the bridge axial direction, and have a horizontal-shaped bottom steel plate 10a on the lower side, and have vertical reinforcement plates 10b and 10c extending in the vertical direction in both end parts in the bridge axial direction of the bottom steel plate 10a, ans have lightweight concrete 11 placed in a steel shell. A joint part 10X in the bridge axial direction is not connected. A first projection part 10h projecting in the bridge axial direction is provided on one side vertical reinforcement plate 10b among two vertical reinforcement plates 10b and 10c opposed in the joint part 10X in the bridge axial direction, and a first recessed part 10g recessed in the bridge axial direction is provided on the other side vertical reinforcement plate 10c. The first projection part 10h and the first recessed part 10g are fitted in a state of interposing a first cushioning material 10j composed of resin between mutual ones.SELECTED DRAWING: Figure 8
【課題】橋軸方向に隣り合う床版パネルの橋軸方向継手部が連結していない床版構造において、上方に設けられる舗装でひび割れを生じ難くできる床版構造を提供すること。【解決手段】床版構造１では、サンドイッチ軽量床版パネル１０Ａ，１０Ｂが橋軸方向に敷設されていて、下側に水平状の底鋼板１０ａを有し、底鋼板１０ａの橋軸方向の両端部に鉛直方向に延びる鉛直補強板１０ｂ，１０ｃを有し、鋼殻内に打設された軽量コンクリート１１を有している。そして、橋軸方向継手部１０Ｘが連結していない。橋軸方向継手部１０Ｘで対向する二つの鉛直補強板１０ｂ，１０ｃのうち、一方側の鉛直補強板１０ｂには橋軸方向に突出する第１凸部１０ｈが設けられ、他方側の鉛直補強板１０ｃには橋軸方向に窪む第１凹部１０ｇが設けられている。第１凸部１０ｈと第１凹部１０ｇは、互いの間に樹脂から成る第１緩衝材１０ｊを介装した状態で嵌合している。【選択図】 図８
