PROBLEM TO BE SOLVED: To provide a concrete assembly structure capable of securing the connection strength of side wall parts and a top board part. SOLUTION: This concrete assembly structure comprises the side wall parts 2, 2 formed on the lateral both sides of the structure; the precast concrete top board part 3 installed between the upper surfaces of the side wall parts 2, 2; and connection means for connecting the side wall parts 2 and the top board part 3. A first connection means is a PC steel member 21 for vertical tightening having a base end affixed to the side wall part 2 and a top end inserted into the top board part 3. A second connection means 38 comprises a sleeve body, a deformed reinforcement 34 having a base end affixed to the top board part 3, a deformed reinforcement 26 having a base end affixed to the side wall part 2, and a filler placed in a sleeve body into which the deformed reinforcement 26 and the deformed reinforcement 34 are inserted. Since the concrete structure is connected by the sleeve body and the deformed reinforcements 26, 34 in addition to the connection by the PC steel member 21 for vertical tightening, the highly reliable and highly strong connection structure can be provided.
