[0004]

However, in the case of the above-described conventional connection structure, the cylindrical projection c is fitted in the elongated fitting hole a, so that the projection c is not fitted in this fitting state. The outer peripheral surface is connected so that only a part thereof is in contact with the fitting hole a,
It lacks stability.

At the time of fitting, the protruding portion b of the protrusion c is inserted into the fitting hole a, and the protruding portion b is used as a detent to establish a fitted state. Since only a small part gets over the portion of the fitting hole a and is in a fitted state, when the work of fitting and removing the projection c in the fitting hole a is repeated several times during construction, this protruding portion Only a part of b is crushed and the detent becomes ineffective, which causes a problem that the connection strength is immediately reduced.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a floor decorative material connecting structure which is excellent in durability and can secure a sufficient connecting strength.

[0007]

In order to solve the above-mentioned problems, the floor decorative material connecting structure of the present invention has a structure in which two adjacent sides of a rectangular floor decorative material are adjacent to each other in the thickness direction of the floor decorative material. In addition to being provided with a cylindrical projection for fitting having a bulge at the tip, a fitting hole for receiving and fitting these projections in the thickness direction of the floor decorative material is provided on the remaining two adjacent sides. By inserting the bulging portion of the protruding portion into the fitting hole of the adjacent floor decorative material and fitting the protruding portion and the fitting hole by using this bulging portion as a detent, a plurality of floor makeup members are fitted. In the connecting structure for connecting the members, the fitting hole is formed in the shape of an elongated hole having a parallel portion that is parallel to the side where the fitting hole is provided in the vertical direction. The outer peripheral surface of the part is formed with a parallel surface cut out so as to contact the parallel part. Bulge portion is formed, in which the parallel portion of the fitting hole is fitted in contact with the parallel surfaces of the protrusions.
