[Embodiment 1]
Embodiment 1 of the present invention will be described below with reference to FIGS. 1 to 5. FIG.
The tile unit 1, as shown in FIGS. 1 to 5, is roughly composed of a base sheet 2, a plurality of tile pieces 3, 3 . . .

[Base sheet]
The base sheet 2 is, for example, a thin sheet made of square paper or synthetic resin of approximately 150 mm×150 mm, and has an adhesive layer 5 (see FIG. 4) coated with a pressure-sensitive adhesive or adhesive on the back side.

[Tile piece]
The tile pieces 3 are made of ceramics, glass, synthetic resin, metal, bamboo, wood, stone, or the like. The tile piece 3 has a surface 3a which is a decorative surface chamfered (specifically, rounded chamfer), a back surface 3b which is a substantially flat joint surface, and a flat surface extending from the back surface 3b to the surface 3a. are arranged on the surface of the base sheet 2 with a predetermined joint space 6 therebetween and adhered to the surface of the base sheet 2 via the adhesion layer 11 .
The adhesive layer 11 is provided on the back surface of the tile piece 3, as shown in FIG. Therefore, the adhesive strength of the adhesive layer 11 is weak, so that the tile piece 3 can be peeled off from the base sheet 2 relatively easily and can be easily attached back.
The tile piece 3 of Embodiment 1 is made of ceramics that is glazed and fired at least on the surface 3a, and has a size of about 22 mm x 22 mm x 6 mm (flat side 3c from the back 3b to the chamfered decorative surface is about 5.5 mm). It has a square plate shape, and 6×6 pieces are arranged with a joint space 6 of 2 mm to 3 mm provided on the surface 3 a of the base sheet 2 .
In addition, the tile pieces 3, 3 ... joint spaces 6 are two sides (two sides adjacent to each other across the corners of the base sheet 2) except for special ones used for the edges of the adherend surface 7 (which will be described later). not on the right side and top side in the figure). As a result, when a plurality of tile units 1, 1, . . . be able to.

[Soft resin joint material]
The soft resin joint material 4 is, for example, a white material containing a soft vinyl chloride resin as a main component, and has water resistance and appropriate elasticity. The soft resin joint material 4 has a double structure of an outer joint member 41 and a middle joint member 42 divided in the thickness direction, and the total thickness is smaller than the thickness of the tile piece 3 (in the first embodiment, the tile piece 5.5 mm (3.5 mm for the middle joint member 42 and 2 mm for the outer joint member 41), which is the same as the side surface 3c of No. 3, and the outer dimensions are substantially the same as the base sheet 2. The soft resin joint material 4 has a lattice-type net shape having through holes 40, 40, which are almost straight in the thickness direction according to the shape and arrangement of 3, 3, etc. , 40, .
In the soft resin joint material 4 of Embodiment 1, the intermediate joint member 42 is attached to the base sheet 2 via the adhesive layer 12, and the outer joint member 41 overlaps the intermediate joint member 42.

In the tile unit 1 of Embodiment 1 having the above configuration, each tile piece 3 has an adhesive strength due to an adhesive layer 11 formed of a weakly adhesive adhesive and a soft adhesive strength attached to the base sheet 2 . It is stably attached to the base sheet 2 by the fitting force with the resin joint material 4 .
When the outer joint member 41 of the soft resin joint material 4 is removed from the tile unit 1, the soft resin joint material 4 becomes only the middle joint member 42, and the fitting depth with the tile piece 3 becomes shallow. The fitting force that holds the
Therefore, the tile piece 3 can be relatively easily made into a base by pressing a fingertip or the tip of a tool such as a slotted screwdriver against the upper part of the side surface 3c of the tile piece 3 hidden by the outer joint member 41 and prying it like a lever. It can be removed from the seat 2.
Further, a new tile piece 3 is mounted in the empty frame of the middle joint member 42 from which the tile piece 3 has been removed, and the outer joint member 41 is fitted again, whereby the tile piece 3 is held by the soft resin joint material 4. Tile piece 3 stabilizes because the force is restored.

[Attachment method]
Next, a method for adhering the tile unit 1 of Embodiment 1 to an adherend surface 7 such as a wall surface in a building room will be described in order from the manufacturing stage.
The adhesive layer 5 on the back surface of the base sheet 2, the adhesive layer 11 of the tile piece 3, and the adhesive layer 12 of the middle joint member 42 are protected by peelable release paper (not shown). The release paper is peeled off just before sticking, or the sticking layer 12 of the intermediate joint member 42 is coated with a sticking agent just before sticking.

First, in the factory, the middle joint member 42 is adhered to the surface of the base sheet 2 with the adhesion layer 12 . The middle joint member 42 thus formed, the intermediate body 10 of the base sheet 2, the outer joint member 41, and the necessary number of tile pieces 3, 3 . . . The user who purchased the above attaches the intermediate body 10 without the tile pieces 3, 3 ... to the adherend surface 7 such as the wall of the house in advance, and then the tiles in the through holes 40, 40 ... of the middle joint member 42. The pieces 3, 3, .

As shown in the perspective view of FIG. 1, all the tile pieces 3, 3, . . . The soft resin joint material 4 is fitted in the forehead holes 40, 40, . It looks like
Further, in Embodiment 1, the thickness of the soft resin joint material 4 obtained by overlapping the outer joint member 41 on the middle joint member 42 is formed to be substantially the same as the height of the side surface 3c of the tile piece 3. The side surface 3c is almost buried in the soft resin joint material 4, and only the chamfered decorative surface protrudes outside, leaving no room for fingertips or the like to get caught. Therefore, there is almost no fear that the tile piece 3 will be peeled off by a fingertip or the like touching the surface 3a of the tile unit 1.

When changing the arrangement of the tile pieces 3 of the tile unit 1 attached to the adherend surface 7 , the outer joint member 41 of the soft resin joint material 4 is first removed from the joint space 6 . As a result, the soft resin joint material 4 is only the middle joint member 42 and the fitting depth with the tile piece 3 is shallow, so the fitting force for holding the tile piece 3 is reduced.
Therefore, it is relatively easy to remove the outer joint member 41 by pressing the top of the side surface 3c of the tile piece 3 exposed by removing the outer joint member 41 with a fingertip or the tip of a tool such as a flathead screwdriver and prying it like a lever. A tile piece 3 can be removed from the base sheet 2 .
Next, the removed tile piece 3 or another tile piece 3 is mounted in the empty frame of the middle joint member 42 from which the tile piece 3 has been removed, and then the outer joint member 41 is fitted back in, resulting in a soft resin joint material. Since the holding force of the tile piece 3 by the 4 is restored, the tile piece 3 can be stabilized.

[Embodiment 2]
In the tile unit 1 of Embodiment 1, the outer joint member 41 is simply placed on the middle joint member 42, but the through hole 40 positioned at the edge of the soft resin joint member 4 is opened in a U-shape. Since the fitting force with the tile piece 3 is small, the edge of the outer joint member 41 may be lifted.
Therefore, in the second embodiment, a weak adhesive is provided between the outer joint member 41 and the intermediate joint member 42 so that the base sheet 2 and the intermediate joint member 42 can be attached and peeled off with an adhesive force smaller than the adhesive force of the adhesive layer 12 of the base sheet 2 and the intermediate joint member 42 . An adhesive layer 13 is interposed. By doing so, the outer joint member 41 can be attached and detached without affecting the connection between the intermediate joint member 42 and the base sheet 2, and the outer joint member 41 is stable in the joint space 6, especially at the edge portion. can improve sexuality.
It should be noted that the weakly sticking adhesive layer 13 of Embodiment 2 is formed on the inner surface side of the outer joint member 41 .

Although the present invention has been described with reference to the first and second embodiments, the present invention is of course not limited to the above embodiments. For example, in the embodiment, the outer joint member 41 of the tile unit 1 is formed in a size corresponding to one base sheet 2, but the outer joint member 41 is formed to cover two base sheets 2 as shown in FIG. It may be formed in a size that can correspond to the above. By doing so, the seams between the tile units 1, 1 can be finished with a natural appearance inconspicuous.
Further, in the embodiment, the intermediate joint member 42 is adhered to the base sheet 2 in the factory to form the intermediate body 10, and the intermediate body 10, the tile piece 3 and the outer joint member 41 are packaged together and supplied to the customer. Although the tile unit 1 is completed by attaching it to the adherend surface 7, the middle joint member 42, the tile piece 3, and the outer joint member 41 are all assembled to the base sheet 2 in the factory before shipment. Alternatively, the consumer may attach it to the adherend surface 7, and even in that case, the benefit of being able to change the pattern can be fully enjoyed.
