<P>PROBLEM TO BE SOLVED: To provide a floor decorative material capable of effectively absorbing such unevenness that cannot be absorbed by only movement in a planar direction in which flooring materials are connected each other, that is, such unevenness of a curve surface or a largely uneven surface of an underfloor ground, or locally or continuously changing inclination. <P>SOLUTION: A connection structure of flooring materials 1 connects adjacent rectangular flooring materials 1 each other. A convex type connecting piece 4 and a recess type connecting piece 5 are provided on an outer peripheral edge of the respective flooring materials 1. The convex type connecting piece 4 of one flooring material 1 can connect to the recess type connecting piece 5 of another adjacent flooring material 1. A tenon 4a having an engaging piece 4c at its end is provided in the convex type connecting piece 4, and a dovetail groove 5a having an engaging pieces receptacle 5c, with which the engaging piece 4c is engaged, is provided in the recess type connecting piece 5, while communicating in a thickness direction of the flooring material 1. The tenon 4a is loosely fitted in the dovetail groove 5a, and the convex type connecting piece 4 and the recess type connecting piece 5 are connected so that the locking piece 4c can be freely moved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
