PROBLEM TO BE SOLVED: To improve workability while securing bending and shearing strength. SOLUTION: A groove Sa is formed in a butting part of floorboards 10A, 10B, a loop part L by reversing parts 15 of the respective floorboards 10A, 10B is formed in this groove Sa, and straight line-shaped main reinforcements 16 are arranged in spaces Sb outside of the loop part L inside of the reversing parts 15. Joining members 18 are installed over the main reinforcement 16 inserted into the reversing part 15 of the floorboard 10A and the reversing part 15 of the mating side floorboard 10B, and the joining members 18 are installed over the main reinforcement 16 inserted into the reversing part 15 of the other floorboard 10B and the reversing part 15 of the mating side floorboard 10A to thereby join the respective main reinforcements 16 to the reversing parts 15. Mortar M is filled in the groove Sa.
