Embodiments Embodiments will be described below with reference to the drawings.

FIG. 1 is a sectional view of a tile construction substrate 11 of a tile construction structure according to an embodiment, and FIG. 2 is a sectional view showing a tile construction structure using this substrate.

On the front surface side of the substrate 11, a ridge 12 extending horizontally in the left-right direction.
Is provided. The ridge 12 has an upper surface that is inclined upward toward the front so that it can be engaged with the dovetail-shaped engaging groove 4 on the back surface of the tile 3.

The ridges 12 are provided in a plurality of stages at predetermined intervals in the vertical direction, and the ridges 12 in the lowest stage are provided along the lower side of the substrate 11. The lower end edge of the lowermost projecting strip 12 projects downward from the lower side of the substrate 11 to form a projecting piece portion 14. Also,
The uppermost protrusion 12 is provided apart from the upper side of the substrate 11.

At the lower side of the substrate 11, the step 13
Is provided. In the present embodiment, the width of the step portion 13 in the thickness direction of the substrate 11 is the same as the main body thickness d of the substrate 11,
It is slightly larger than that, and no step is provided on the upper side of the substrate 11.

When this substrate 11 is attached to the frame, the upper side portion of the lower substrate 11 is fitted to the lower step portion 13 of the substrate 11 adjacent to the upper side.

As is clear from FIG. 1, the thickness of the lower side of the substrate 11 is the thickness of the main body of the substrate plus the thickness of the ridges 12, and even if the thickness of the main body is small, the thickness of the substrate is small. Since the thickness of the lower side portion of the substrate 11 is considerably large, even if the step portion 13 is formed, the strength of the projecting piece portion 14 at the lower end portion of the substrate is sufficiently high. Similarly, no step is provided in the upper side portion of the substrate, and the strength of the upper side portion is sufficiently high.

As shown in FIG. 2, an adhesive 15 is filled in the lower portion of the engaging groove 4 of the tile 3 locked to each ridge 12, so that the tile 3 is fixed to the substrate 11.

In addition, as shown in FIG. 2, the adhesive 15 in the engaging groove 4 of the tile 3 which is locked to the lowermost protrusion 12 of the upper substrate 11 is the lower end surface of the upper substrate 11. The front surface of the upper end of the substrate 11 on the lower side; and the back surface of the tile 3 that is locked to the protrusions 12 on the lowermost stage of the upper substrate 11. Therefore, the adhesive 15 bonds the upper and lower substrates 11 to each other; seals the seams between the upper and lower substrates 11; and joins the tiles 3 and the substrate 11 locked to the lowermost protrusion 12 to each other. It is possible to obtain the following three effects. In addition, since the tile adhesive and the substrate sealing adhesive can be used in this way, the adhesive filling work can be done only once, and the processing efficiency is high.

Incidentally, when the lower half portion 12A of the ridge 12 is arranged on the upper side portion of the lower substrate 11 as shown in FIG. 4 shown as a reference example, the adhesive 16 for seam sealing of the substrate 11 and the tile attachment It is necessary to separately attach the adhesive 15 for use, and the construction work becomes more troublesome.

In the above-described embodiment, as shown in FIG. 2, a gap is formed between the vertical surface of the engaging groove 4 (the surface parallel to the tile front surface) and the front surface of the protrusion 12. Even if the lower substrate 11 and the lower substrate 11 come in and out, the tile 3 can be attached so as to extend over both substrates.

In the above embodiment, the step portion is not provided on the upper side portion of the substrate 11, but in the present invention, the step portion 17 may be provided on the upper side portion of the substrate 11 as shown in FIG.

It should be noted that when the substrate material is a hard wood chip cement plate, it is extremely effective to adopt the configuration of the present invention when the main body thickness d of the substrate is a thin product of about 10 mm or less.

In the above embodiment, the adhesive is adhered only to the lower side of the engaging groove of the tile, but it is also possible to adhere the adhesive to the upper part of the engaging groove (the portion 20 in FIG. 2). it is obvious.

[Effect] As described above, according to the tile construction structure of the present invention, it is possible to improve the strength of the step portion formed on the lower side portion or the upper and lower side portions of the tile construction substrate used for construction. In addition, the number of adhesive adhesion steps during tile construction can be reduced to improve the construction efficiency.
