PROBLEM TO BE SOLVED: To reduce cracks appearing in a concrete structure due to concrete shrinkage, and to enhance construction efficiency.SOLUTION: Concrete is poured so that a slit S can be formed in a part of a reinforced concrete structure 10. In that case, a jaw 20 protruding to the downside of the slit S is provided in a column 16 or a girder, which is one of concrete members on both sides sandwiching the slit S. The girder 14 or a slab, which is the other one of the concrete members on both the sides, is placed on the jaw 20 so that the downside of the slit S can be closed with the jaw 20. After the lapse of a predetermined period of time from the placing of the concrete, the slit S having the downside closed with the jaw 20 is filled with shrinkage-compensating mortar M. |
