PURPOSE: To provide a concrete structure, by which construction can be facilitated, in a large section member, and occurrence of cracks and local shear fracture can be reduced.

CONSTITUTION: The n+l th layer concrete 3-(n+1) is placed on the n-th layer concrete 3-n, and a reinforcement net 5-(n+1) is laid thereon. Thus, concrete is placed and a reinforcement net is laid on the whole surface repeatedly to construct a plate-like structure 1.
