<p>Disclosed herein is a floor board capable of absorbing deformation by expansion and contraction, which is utilized as an edge finishing material of a laminate floor board that is to be constructed, or as an intermediate material between laminate floor boards, or as an extending/finishing profile of a trim boundary that partitions a space into sections, thus effectively absorbing an expansion and contraction ratio of the laminate floor board due to a change in temperature and moisture and thereby minimizing deformation of a constructed state. The floor board is industrially manufactured by extrusion molding, and is configured such that adjacent hard resin plates are joined to each other by a joining member made of flexible soft resin or flexible foam resin, both hard resin plates located at outermost positions having the same tongue-groove structure as a tongue-groove coupling structure of a constructed laminate floor board.</p> |
