<P>PROBLEM TO BE SOLVED: To provide a solid structure of a floor material, capable of preventing a gap and preventing an adhesive from overflowing from between division pieces. <P>SOLUTION: A male solid part 4 formed at a side end of one division piece 2 and a female solid part 6 formed at a side end of the other division piece 3 are engaged. The male solid part 4 has a projection 5 projected downwards, and the female solid part 6 has a recess 7 opened upwards. When the division piece 2 and the division piece 3 are connected, upper side parts 13 and 11b of both are abutted and a space 15 is formed below them. The space 15 reaches between a lower end 5a of the projection 5 and a bottom 7a of the recess 7, and an adhesive 9 provided in the space 15 is spread inside the space 15 with less resistance than a gap 16 between the upper side parts 13 and 11b of both the division pieces 2 and 3 to dissolve the gap of both the division pieces 2 and 3 and prevent the adhesive 9 from overflowing from the gap 16. <P>COPYRIGHT: (C)2013,JPO&INPIT |
