JOINT STRUCTURE OF PRECAST COMPOSITE FLOOR SLAB
To provide a joint structure of precast composite floor slab having excellent workability and economical efficiency.SOLUTION: A joint structure B for joining composite floor slabs A1, A2 formed by placing concrete 2 above a bottom steel plate 1 and integrally molding the bottom steel plate 1 and the concrete 2, and having a widened section 10a at the tip, comprises: a reinforcing bar 10 having a mechanical anchorage arranged to protrude to a tip part side from a joint end face 3 of the composite floor slabs A1, A2; a splice plate 4 disposed to be superimposed on the end side of the bottom steel plate 1 of the adjacent composite floor slabs A1, A2; high strength bolts 7 and nuts 5 for connecting the splice plate 4 to both bottom steel plates 1 of the adjacent composite floor slabs A1, A2; and infilling concrete 8 filled between the joint end faces 3 of the adjacent composite floor slabs A1, A2 so as to embed the reinforcing bar 10 having the mechanical anchorage.SELECTED DRAWING: Figure 1
【課題】施工性、経済性に優れたプレキャスト合成床版の継手構造を提供する。【解決手段】底鋼板１の上方にコンクリート２を打設し、底鋼板１とコンクリート２を一体成形してなる合成床版Ａ１、Ａ２同士を接合するための継手構造Ｂであって、先端部に拡幅部１０ａを備え、合成床版Ａ１、Ａ２の接合端面３から先端部側を突出して配設される機械式定着部を有する鉄筋１０と、隣り合う合成床版Ａ１、Ａ２の底鋼板１の端部側同士に重ねて配設される添接板４と、添接板４を隣り合う合成床版Ａ１、Ａ２の両底鋼板１に接続するための高力ボルト７及びナット５と、機械式定着部を有する鉄筋１０を埋設するように隣り合う合成床版Ａ１、Ａ２の接合端面３同士の間に充填される間詰めコンクリート８とを備えて構成する。【選択図】図１
