NON-WELDING SPACER METAL FITTING OF REINFORCED CAGE
PROBLEM TO BE SOLVED: To provide a non-welding spacer metal fitting of a reinforced cage, easily fixable without welding, in a state of surely swelling a swelling part to the outside of the reinforced cage.SOLUTION: In a state of wrapping-holding from the falling direction of a swelling part 23 by inserting an outside part in the circumferential direction of a main reinforcement 11 into a cutout hole of a first piece 24 together with a standing part 29 of the swelling part 23 of a spacer 21 in four places of an equal interval in the circumferential direction of a reinforced cage body, screw parts 34 and 34 of a U-shaped bolt 27 of wrapping-holding the main reinforcement 11 together with a proximity side end part 32 of the spacer 21 from the inner surface side of the reinforced cage body, are inserted into a bolt insertion hole 33 of a second piece 25 and are fastened by a but 28, so that the second piece 25 is firmly fixed to the main reinforcement 11 together with the proximity side end part 32 of the spacer 21 while making the cutout hole of the first piece 24 bite in an outside part in the circumferential direction of the main reinforcement 11 and the standing part 29 of the swelling part 23 of the spacer 21 by fastening of the U-shaped bolt 27 and the nut 28.
【課題】鉄筋籠の外方へ膨出部を確実に膨出させた状態で無溶接により簡単に固定することができる鉄筋籠の無溶接スペーサー金具を提供する。【解決手段】鉄筋籠本体の周方向等間隔の４箇所において主筋１１の周方向外側部分をスペーサー２１の膨出部２３の立ち上がり部分２９と共に第１片２４の切欠穴に挿通して膨出部２３の倒れ方向から包持した状態で、主筋１１を鉄筋籠本体の内面側からスペーサー２１の近接側端部３２と共に包持したＵ字ボルト２７の螺子部３４，３４を第２片２５のボルト挿通孔３３に挿通してナット２８で締結することで、Ｕ字ボルト２７及びナット２８の締め付けによって、第１片２４の切欠穴を主筋１１の周方向外側部分及びスペーサー２１の膨出部２３の立ち上がり部分２９に食い込ませながら、第２片２５をスペーサー２１の近接側端部３２と共に主筋１１に対し強固に固定している。【選択図】図３
