The vertical crosspieces 13 and the horizontal crosspieces 14 each having a rectangular cross section are formed in a lattice shape. A large number of rectangular openings 15 are arranged as a space between the vertical rails 13 and the horizontal rails 14. In this case, the distance T between the facing edges of the two vertical bars 13 and 13 that form the opening 15 is determined by the pair of engaging pieces 31 on the tile 30 side.
It is slightly wider than the interval S1 between the straight plate portions 31a and 31a of 31 and smaller than the dimension S2 between the tips of the engaging claws 32 and 32. Further, the size of the opening 15 is naturally smaller than the tile 30. In addition, the substrate portion 1 of the resin mat 11
On the lower surface of 2, the substrate portion 12 is held at a predetermined height from the floor base surface 40, and a space 18 having an appropriate height is provided below the substrate portion 12.
A supporting leg portion 17 is provided so as to secure the position. The support leg portions 17 are arranged at the intersections of the vertical rails 13 and the horizontal rails 14.

Next, the procedure for assembling the composite flooring material 10 having the above structure and its operation will be described. When fixing the tile 30 to the resin mat 11, as shown in FIG. 2A, the tile 30 is lowered onto the upper surface of the substrate portion 12 of the resin mat 11 in a horizontal posture and placed in the opening 15 formed in the substrate portion 12. , Four engaging pieces 31 protruding from the bottom surface of the tile 30
Push in. Then, the outer inclined surface of the engaging claw 32 of each engaging piece 31 hits the vertical crosspiece (the edge portion of the opening 15) 13, whereby the engaging piece 31 is bent inward, and the tile 30 is further moved downward. By being pushed down, the engaging claw 32 reaches the lower side of the vertical bar 13. And the engagement piece 3
By elastically returning 1 on the lower surface side (back side) of the base plate portion 12, the tip end of the engaging claw 32 engages with the lower surface of the vertical bar 13 corresponding to the edge of the opening 15, and thereby the tile 30.
Are fixed to the resin mat 11. In this case, since the engaging pieces 31 are provided at the positions corresponding to the respective corners of the square tile 30, the tile 30 can be fixed to the resin mat 11 in a stable state.

Since the tile 30 can be easily attached by pressing the tile 30 from above toward the resin mat 11 in this manner, the floor base surface 40 is previously prepared.
The resin mat 11 is laid on the
Can be attached to complete the tile floor surface.
On the other hand, when removing the tile 30 from the resin mat 11, the engaging piece 31 is forcibly bent while strongly lifting the tile 30. Then, the engagement state of the engagement claw 32 is released, and the tile 30 can be removed from the resin mat 11.

In the above embodiment, the size of the opening 15 corresponds to the size of the tile 30, and the tile 30 and the opening 1
5 have a one-to-one relationship, but the openings 15 are tiles 3
The tiles 30 can be arranged in various arrangements by forming them smaller than 0 and arranging them vertically and horizontally so that the openings 15 for engaging the engaging pieces 31 can be appropriately selected. The sequence of 30 and the like can be freely decided by the end user. Further, various sizes, shapes, and colors of tiles can be prepared, and the tiles can be freely attached to the resin mat 11 to form floor surfaces having various tile patterns.
Further, as for the construction procedure, instead of laying the resin mat 11 on the floor base surface 40 first and then disposing the tile 30 as described above, the tile 30 is attached to the resin mat 11 in advance, and the tile 30 is constructed. It may be cut according to the size of the place and laid on the floor base surface 40.

Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, the cross-sectional shape of the vertical bar 13 of the resin mat is not a simple rectangle but a shape in which the inclined surface 13a is formed at the lower surface side edge portion. Other configurations are the same as those in the above embodiment. The inclined surface 13a faces the engaging piece 31 side, and the tip of the engaging claw 32 is in pressure contact with the inclined surface 13a. When the tip of the engaging claw 32 comes into pressure contact with the inclined surface 13a in this way, the engaging claw 32 receives the reaction force F in the lateral direction from the inclined surface 13a, so rattling in the same direction is prevented. , Tile 30
Is held stable. Further, since the sliding of the engagement claw 32 is pressed by the reaction force F, even if any external force acts on the engagement piece 31, the engagement claw 32 is unlikely to shift and the fixing force of the tile 30 increases.

In the embodiment shown in FIG. 4, the slope 13a of the embodiment shown in FIG. 3 is further enlarged so that the vertical bar 23 has a triangular cross section. The same effect is achieved in the case of the inclined surface 23a of the vertical bar 23. FIG. 5 shows the operation until the engaging claw 32 is engaged with the vertical rail 23 of the embodiment shown in FIG. As shown in FIG. 5A, the engaging piece 31 is inserted from above.
Is pushed into the opening 15, the outer inclined surface of the engaging claw 32 hits the vertical bar 23 and the engaging claw 32 bends (actually, the engaging piece 3
1 itself bends). Further, when the engaging piece 31 is pushed downward, the tip of the engaging claw 32 passes through the upper edge of the vertical bar 23 and slides toward the inclined surface 23a. When the engagement piece 31 is further pushed down in this state, the engagement claw 32 slides on the inclined surface 23a while being in pressure contact, and stops at a stable position.
In this state, the engaging claw 32 is elastic and has an inclined surface 23a.
Since it is in pressure contact with, the engaging claw 32 is restrained so as not to rattle by receiving a reaction force from the inclined surface 23a.

[0020]

As described above, according to the first aspect of the invention, the tile is simply pressed against the resin mat,
The tile can be fixed by the engaging piece. Therefore, the tiles can be easily attached, and the tiles can be attached later after the resin mat has been laid at the construction site first, and the tile floor surface can be easily constructed. Further, when the tile is strongly lifted up, the engaging piece is flexibly deformed and the engaged state is released, so that the tile can be removed from the resin mat. Therefore, it is possible to easily replace the tile even if the operator is not a specialist. Further, if the openings are appropriately dispersed and formed, the positions of the openings with which the engaging pieces are engaged can be selected, so that the arrangement and arrangement of the tiles can be freely set and the tiles can be freely arranged. Even tiles of different sizes and shapes can be freely selected and combined to be attached, and the degree of freedom in designing tiles can be increased. Further, as a means for joining the tile to the resin mat, it is only necessary to provide an opening on the resin mat side and to bury the engaging piece on the tile side, so that the structure is simple and can be realized at low cost. It is also very suitable when using tiles.

According to the second aspect of the present invention, since the engaging piece is formed by bending the metal plate into a substantially inverted V shape, the flexibility of the engaging piece can be increased and the strength can be increased. Can be sufficiently secured. Therefore, the durability is improved and the workability at the time of attaching and detaching the tile is improved. Further, since the tip of the substantially rectangular metal plate is engaged with the edge of the opening, the tile can be firmly held with elasticity.
