GROUT INJECTION METHOD
PROBLEM TO BE SOLVED: To suppress inflow of a grout into a through-hole from another through-hole, for ensuring reliability of grout filling.SOLUTION: A grout injection method includes the following steps for: communicating a plurality of connection holes (sleeves 22) formed on a top edge surface 12A of a lower column member 12 with a through-hole (a sheath pipe 24) penetrating through a connection part 14A of a beam member (a first beam member 14) in a vertical direction using communicating means (a packing 26), and forming a gap 62A between the lower column member 12 and the connection part 14A; forming a gap 66A between an upper column member 18 and the connection part 14A while inserting a reinforcing bar (a column reinforcing bar 44) protruding from a lower edge surface 18A of the upper column member 18 into the through-hole, the communicating means and the connection hole; and injecting grout from the connection hole for filling the grout in the connection hole, the communicating means, and the through-hole.SELECTED DRAWING: Figure 1
【課題】一の貫通孔から他の貫通孔にグラウトが流入することを抑制して、グラウト充填の確実性を高める。【解決手段】グラウト注入方法は、下柱部材１２の上端面１２Ａに設けられた複数の接続孔（スリーブ２２）と、梁部材（第１梁部材１４）の仕口部１４Ａを上下方向へ貫通する貫通孔（シース管２４）とを、連通手段（パッキン２６）を介して連通させると共に、下柱部材１２と仕口部１４Ａとの間に隙間６２Ａを形成する工程と、貫通孔、連通手段及び接続孔へ、上柱部材１８の下端面１８Ａから突出した鉄筋（柱鉄筋４４）を差し込んだ状態で、上柱部材１８と仕口部１４Ａとの間に隙間６６Ａを形成する工程と、接続孔からそれぞれグラウトを注入して、接続孔、連通手段、及び貫通孔にグラウトを充填する工程と、を有する。【選択図】図１
