また、本発明の雌嵌合部は、上記実施形態の雌嵌合部70、71に限定されるものではなく、雄嵌合部6に嵌合させてユニット床材同士を連結できる構造を有していればよい。   Moreover, the female fitting part of this invention is not limited to the female fitting parts 70 and 71 of the said embodiment, It has a structure which can be fitted to the male fitting part 6 and unit floor materials can be connected. If you do.

また、ユニット床材1a〜1cはいずれも、全てが合成樹脂で形成されているが、これに限られず、例えば、枠体3a〜3cを合成樹脂で形成し、表面材2に磁器タイル、木材タイル、無機焼結タイルなどを用いてもよい。さらに、表面材2と枠体3a〜3cとは、接着による固定に限られず、ビスなどの係止具で固定してもよい。また、枠体3a〜3cの形状は、上記実施形態に限られず、任意の形状で構わない。 Moreover, none of the units flooring 1 a to 1 c, but everything is made of synthetic resin is not limited to this, for example, to form a frame 3a~3c a synthetic resin, ceramic tile surface member 2 Wood tiles, inorganic sintered tiles, and the like may be used. Furthermore, the surface material 2 and the frames 3a to 3c are not limited to fixation by adhesion, and may be fixed by a locking tool such as a screw. Moreover, the shape of the frame bodies 3a-3c is not restricted to the said embodiment, Arbitrary shapes may be sufficient.

また、切欠き溝9,9は、必ずしも必要ではなく、雌嵌合部70に、無負荷状態で本体部側の基端部から先端に向かって水平面に対して下り勾配となる傾斜状態になり、ユニット床材が載置面に載置されたとき雌嵌合部の底面がユニット床材の載置面に沿う可撓性を付与する手段が設けられていればよい。したがって、例えば、側壁8における雌嵌合部70との連接部分を弾性材料で形成してもよいし、雌嵌合部70の側壁8側の基端部を弾性材料で形成してもよい。   Further, the notched grooves 9 and 9 are not necessarily required, and the female fitting portion 70 is inclined so as to be inclined downward with respect to the horizontal plane from the proximal end portion on the main body portion side toward the distal end in an unloaded state. When the unit flooring is placed on the placement surface, it is only necessary to provide means for providing flexibility so that the bottom surface of the female fitting portion follows the placement surface of the unit flooring. Therefore, for example, the connecting portion of the side wall 8 with the female fitting portion 70 may be formed of an elastic material, or the base end portion on the side wall 8 side of the female fitting portion 70 may be formed of an elastic material.
