To provide a reinforcement cage which mounts a vertical reinforcement for reinforcement on a head of a columnar structure without welding, and a method for mounting the same.SOLUTION: A reinforcement cage 1 is constituted so that an upper end of an inversely L-shaped suspension vertical reinforcement 10 is restricted by a guide body 20, and an upper end thereof is restricted by a bottom side restraint body 30 such as a lower end hoop reinforcement 31. The guide body 20 of the reinforcement cage 1 has a double structure of inner and outer guide bodies 22 and 21 and forms an engagement mechanism that sandwiches and engages a vertical reinforcement 80 for reinforcement at an interval δ1 between the inner and outer guide bodies 22 and 21, a lower end of the vertical reinforcement 80 for reinforcement can be mounted on the hoop reinforcement 31, the vertical reinforcement 80 for reinforcement can be held by the guide body 20 and the bottom side restraint body 30 in an erected state in the reinforcement cage 1, thereby concrete is placed in a hollow space 6 of a columnar structure 5 in a state in which the vertical reinforcement 80 for reinforcement is held by the reinforcement cage 1 mounted in the hollow space 6, and thereby the vertical reinforcement 80 for reinforcement can be mounted on the columnar structure 5 without welding.SELECTED DRAWING: Figure 1 【課題】一切溶接を行うことなく柱状構造物の頭部に補強用縦筋を取り付けられる鉄筋籠およびその取り付け方法を提供する。【解決手段】逆Ｌ字形状の吊鉄筋１０の上端側をガイド体２０で拘束し，下端側を下端側フープ筋３１等の底部側拘束体３０で拘束して鉄筋籠１を構成する。鉄筋籠１の前記ガイド体２０を，内側，外側ガイド体２２，２１から成る二重構造として内側，外側ガイド体２２，２１間の間隔δ１で，補強用縦筋８０を挟持して係止する係止機構を形成し，補強用縦筋８０の下端をフープ筋３１上に載置可能として，前記ガイド体２０と前記底部側拘束体３０とで，補強用縦筋８０を鉄筋籠１内部に立設状態に保持可能とすることで，柱状構造物５の中空空間６に取り付けた鉄筋籠１に補強用縦筋８０を保持させた状態で中空空間６にコンクリートを打設することで，補強用縦筋８０に対する一切の溶接を行うことなく，柱状構造物５に取り付け可能である。【選択図】図１
