PRECAST CONCRETE FLOOR BOARD CONNECTION STRUCTURE AND CONNECTION METHOD
PROBLEM TO BE SOLVED: To provide a precast concrete floor board connection structure, which can be constructed by a simple work and enables a precast concrete floor board to be easily removed.SOLUTION: A precast concrete floor board connection structure comprises: spacers 4, which extend across a width direction of a flange top face 31a of steel beam 3 and are disposed with a space between adjacent spacers in a lengthwise direction of the steel beam 3; and a nonshrinkage mortar 5, which is charged between the spacers 4. The spacer 4 is made of a member that is compressively deformed by self-weight of a PC floor board 1. A fill ration of the nonshrinkage mortar 5 is larger than a volume of a filling area surrounded by spacers 4 that are compressively deformed by self-weight of PC floor board 1, the PC floor board 1 and the flange top face 31a before the PC floor board 1 is laid on the spacers 4.SELECTED DRAWING: Figure 3
【課題】簡単な作業により施工することができ、かつプレキャストコンクリート床板の取り外しを容易に行うことができる。【解決手段】鉄骨梁３のフランジ上面３１ａの幅方向の全体にわたって延在し、かつ鉄骨梁３の長さ方向に間隔をあけて配置されるスペーサ４と、スペーサ４同士の間に充填される無収縮モルタル５とを備え、スペーサ４はＰＣ床板１の自重によって圧縮変形する部材からなり、無収縮モルタル５は、スペーサ４上にＰＣ床板１を載置する前において、ＰＣ床板１の自重によって圧縮変形した状態のスペーサ４と、ＰＣ床板１と、フランジ上面３１ａとによって囲まれる充填領域の体積よりも大きな充填量で設けられた構成のプレキャストコンクリート床板における接合構造を提供する。【選択図】図３
