PURPOSE:To improve operating efficiency by simplifying joint operation while enhancing the reliability of the strength of a section. CONSTITUTION:In the joint structure of a precast concrete board, a recessed section 3 with a flat surface 3B is formed to the underside 2C of the precast concrete board 2, and the bent end section 5B of an L-shaped reinforcing bar 5 for joint buried into the inside from the flat surface 3B is projected to a lower section. A recessed section 8, which receives the bent end section 5B at a place corresponding to the bent end section 5B while being filled with mortar M1, is formed to the top face 6C of a stair landing 6 of upper and lower stairs. When the precast concrete board 2 and the stair landing 6 are joined, the recessed section 8 is filled with mortar M1, and the recessed section 3 of the precast concrete board 2 is placed on the joint section 6A of the stair landing 6 while the bent end section 5B is inserted into the recessed section 8, thus joining the precast concrete board 2 with the stair landing 6.
