PROBLEM TO BE SOLVED: To provide a method of joining concrete members, capable of preventing a junction prepared for earthquake from increasing in cross section and an amount of reinforcement from increasing and also capable of reliably transmitting axial force.SOLUTION: A method of joining concrete members, in which a pile cap 5 is joined to a top face of an intermediate wall 4, includes: an elastic deformation material laying step of laying an elastic deformation material 7 so as to surround a joint bar insertion hole 41 formed in a top face of the intermediate wall 4; a level matching step of positioning the pipe cap 5 with an interval from the top face of the intermediate wall 4, and defining a backfill space A by the top face of the intermediate wall 4, the pile cap 5, and the elastic deformation material 7; a joining step of inserting a joint bar 9 from a joint bar open hole 51 formed in the pile cap 5 facing the joint bar insertion hole 41 and joining the intermediate wall 4 and the pile cap 5; and a grout backfill step of filling the backfill space A with grout. 【課題】本発明は、地震に備えた接合部の大断面化や鉄筋量の増加を防止できると共に、軸力を確実に伝達することができるコンクリート部材の接合方法を提供する。【解決手段】中壁４の頂面に頂版５を接合するコンクリート部材の接合方法であって、中壁４の頂面に形成されたジョイントバー挿入穴４１を囲むように弾性変形材７を敷設する弾性変形材敷設工程と、頂版５を中壁４の頂面に対して間隔をおいて位置決めし、中壁４の頂面と頂版５と弾性変形材７とで充填空間Ａを画定するレベル合わせ工程と、ジョイントバー挿入穴４１に対向して頂版５に形成されたジョイントバー貫通孔５１からジョイントバー９を挿入して中壁４と頂版５とを接合する接合工程と、充填空間Ａにグラウトを充填するグラウト充填工程とを有する。【選択図】図４
