CONNECTION METHOD FOR VERTICAL REINFORCEMENT CAGE
PROBLEM TO BE SOLVED: To provide a connection method for vertical reinforcement cages on top and bottom that allows positional adjustment operation to be easily performed.SOLUTION: After setting a first joint 30 at a top edge of a first main reinforcement 11 among main reinforcements of a lower vertical reinforcement cage 10 and setting a second joint 40 at a top edge of a remaining second main reinforcement 12, the top edge of the first main reinforcement 11 is inserted into a lower part of the first joint 30 to bring an open edge at a top part of the first joint 30 above the top edge surface of the first main reinforcement 11, and the top edge of the second main reinforcement 12 is inserted through an entire length of the second joint 40 to bring an opening edge at a top part of the second joint 40 at a same height with or below the top edge surface of the second main reinforcement 12. Then, an upper vertical reinforcement cage 20 is lowered and a lower edge of a third main reinforcement 21 that corresponds to the first main reinforcement 11 is inserted into a top part of the first joint 30. The second joint 40 is lifted and a lower edge of a fourth main reinforcement 22 that corresponds to the second main reinforcement 12 is inserted into a top part of the second joint 40. Furthermore, a grout material is filled in the first and second joints 30, 40.SELECTED DRAWING: Figure 1
【課題】上下の垂直鉄筋籠の接合に際し、位置調整作業を容易にできる方法を提供する。【解決手段】下側の垂直鉄筋籠１０の主筋のうち、第１主筋１１の上端部に第１継手３０をセットし、残りの第２主筋１２の上端部に第２継手４０をセットした後、第１継手３０の下部に第１鉄筋１１の上端部を挿入させることにより第１継手３０の上側の開口端を第１主筋１１の上端面より上方に位置させ、第２継手４０の全長にわたって第２鉄筋１２の上端部を挿入させることにより、第２継手４０の上側の開口端を第２主筋１２の上端面と同一高さかこれよりも下方に位置させる。次に、上側の垂直鉄筋籠２０を下方に移動させ、第１主筋１１に対応する第３主筋２１の下端部を、第１継手３０の上部に挿入し、第２継手４０を上方に移動させ、第２主筋１２に対応する第４主筋２２の下端部を、第２継手４０の上部に挿入し、第１、第２の継手３０，４０にグラウト材の充填を行う。【選択図】図１
