PROBLEM TO BE SOLVED: To provide a joining structure constructible in a short work time by simple work, and having large strength (particularly, resistance force to tensile force), without requiring to execute work for directly connecting mutual reinforcement bars in a cement molding body, in the joining structure formed by joining the mutual cement molding bodies.SOLUTION: A joining structure 1 is composed of a first cement molding body 2, a second cement molding body 2' to be joined to the first cement molding body 2 and a joint member 6 to be interposed between the first cement molding body 2 and the second cement molding body 2'. In the joining structure 1, a joining part of the first cement molding body 2 and the second cement molding body 2' has tensile strength of 5N/mmor more even on any part of the first cement molding body 2 and the second cement molding body 2'.SELECTED DRAWING: Figure 1 |
