To propose a highly reliable joint structure for a precast floor slab and a steel girder, and a joining method for a floor slab, which can shorten a construction period.SOLUTION: A joint structure 1 between a main girder 2 and a precast floor slab 3 mounted on the main girder 2 includes: a bracket 4 fixed to the main girder 2; a connection member 5 fixed to the bracket 4; a concrete block 6 inserted in a blockout 31 formed on the precast floor slab 3; and a filler 7 filled in a space between an inner surface of the blockout 31 and the concrete block 6. An upper part of the connection member 5 is embedded in the concrete block 6.SELECTED DRAWING: Figure 1 【課題】工期短縮化を図ることができ、なおかつ、信頼性の高いプレキャスト床版と鋼桁との接合構造および床版の接合方法を提案する。【解決手段】主桁２と、主桁２に上載されたプレキャスト床版３との接合構造１であって、主桁２に固定されたブラケット４と、ブラケット４に固定された接続部材５と、プレキャスト床版３に形成された箱抜き３１に挿入されたコンクリートブロック６と、箱抜き３１の内面とコンクリートブロック６との隙間に充填された充填材７とを有し、接続部材５の上部はコンクリートブロック６に埋設されている。【選択図】図１
