PROBLEM TO BE SOLVED: To reduce the reinforcement assembling work and the hoisting work on a working scaffold, and to shorten the construction period of the concrete structure. SOLUTION: A first concrete frame 4 is provided with a rectangular frame main body 8 mad of precast concrete, and an inner surface 8A of the frame main body 8 is provided with ribs 12 having trapezoidal cross section. Plural cracking dispersing beams are embedded in side of the frame main body 8 in the grid-like condition. Plural sharing reinforcing beams 16 are provided in the condition that each intermediate part thereof is embedded in the rib 12, and extended in parallel with the inner surface 8A and an upper and a lower edges with a space between the inner surface 8A of the frame main body 8, and provided in the extending direction of a right and a left edges. Both ends of each sharing reinforcing beam 16 are formed with bent parts 1602, 1604 so that an end of the shearing reinforcing beam 16 is projected from the inner surface 8A of the concrete frame 2 at a right angle in the condition that the concrete frame 2 is assembled. |
