Both sleeper pieces 2, 3 are longitudinal materials and include connection parts 8, 8 at the longitudinal edges, and the connection parts 8, 8 include notch parts 15, 15 each of which is notched from the edge surface to the center in the longitudinal direction. The notch part 15 of one side 2 of the sleeper pieces can form connection holes extending in the direction orthogonal to the longitudinal direction together with the notch part 15 of the other side 3 of the sleeper pieces. The connection member 5 is configured so as to be inserted into the connection holes when the two sleeper pieces 2, 3 are connected to each other.</p> |
