COLUMN-BEAM JOINT METHOD AND COLUMN-BEAM JOINT STRUCTURE
To improve the degree of freedom of construction in a precast concrete structure and to reduce the cost.SOLUTION: A precast column member 12 with a concave column-side shear key 21 is erected at a predetermined position, and a removable temporary support member (23) is attached to the precast column member 12. The end of a precast beam member 13 with a concave beam-side shear key 20 at the end face is placed on the temporary support member (23) so as to face the column-side shear key 21 and the beam-side shear key 20 each other. The void G formed between the precast beam member 13 and the precast column member 12 is filled with a filler material 14. A tension member 15 is placed over the precast beam member 13 and the precast column member 14, and after the filler 14 is cured, prestress is introduced into the precast beam member 13 and precast column member 12 by applying tension to the tension member 15.SELECTED DRAWING: Figure 5
【課題】プレキャストコンクリート構造物における施工の自由度を向上し、且つコストを低減する。【解決手段】凹形状の柱側シアキー２１を有するプレキャスト柱部材１２を所定の位置に立設し、プレキャスト柱部材１２に、着脱可能な仮支持部材（２３）を取り付ける。凹形状の梁側シアキー２０を端面に有するプレキャスト梁部材１３の端部を仮支持部材（２３）の上に載置し、柱側シアキー２１と梁側シアキー２０とを対向させる。プレキャスト梁部材１３とプレキャスト柱部材１２との間に形成される空隙Ｇに充填材１４を充填する。プレキャスト梁部材１３とプレキャスト柱部材１４とに亘るように緊張材１５を配置し、充填材１４が硬化した後に、緊張材１５に緊張力を付与することでプレキャスト梁部材１３及びプレキャスト柱部材１２にプレストレスを導入する。【選択図】図５
