That is, the front surfaces of the wall tiles are connected with a connecting sheet and fixed to the outer frame, and in this state, mortar or the like is poured onto the back side of the wall tiles to fix each wall tile to the frame, and then the outer frame and A construction method is known in which a connecting sheet is removed from a wall tile surface and a tile wall surface is formed there.

However, when the construction surface is a floor surface, that is, when floor tile construction is performed, such a method cannot be adopted.

Here, the present invention connects such floor tiles to each other by closely adhering a resin sheet to their back surfaces,
It was constructed so that it could be made into a unit. If the floor tiles are made into units in advance in this way, there is no need to allocate each floor tile or adjust the joint width between the tiles when constructing the tile floor surface. Since the tiles only need to be fixed in place, no skill is required for the tile construction work, and the construction can be done easily and in a short time, resulting in lower construction costs.

[Second solution] The second solution of the present application is also related to a floor tile unit, and its gist is that a part of the resin sheet is inserted into the gap between the floor tiles arranged in a predetermined arrangement. At the same time, a joint crosspiece was inserted from the back side, and the resin sheet protruding into the gap was molded to cover the joint crosspiece, and the joint between the tiles was formed by the joint crosspiece and the resin sheet covering it. There is a particular thing.

[Operations and Effects of Second Solution Means] Since the floor tile unit of the present invention is provided with joints to be formed between tiles in advance, there is no need to perform joint filling work during construction. This not only simplifies tile construction, but also eliminates the need for expensive joint material, which has the advantage of lowering construction costs.

[Third solution] The third solution of the present application relates to a method for manufacturing a floor tile unit, and its gist is to arrange a plurality of floor tiles in a predetermined manner upside down on the tile support surface of a holding form. At the same time, a thermoplastic resin sheet is placed so as to cover the back side of the floor tiles, and then heated and softened, or a thermoplastic resin sheet that has been heated and softened in advance is placed on the back side of the floor tile. At the same time or thereafter, the thermoplastic resin sheet is suctioned from the tile surface side through the suction recesses formed in the holding formwork and through the gaps between the tiles, thereby applying the softened thermoplastic resin sheet to each floor tile. The purpose is to connect the floor tiles to each other by bringing them into close contact with each other on the back side.

[Operations and effects of the third solution] According to this method, the thermoplastic resin sheet can be extremely easily fixed to the back surface of the tile, and each floor tile can be connected to each other.

Moreover, according to this method, the thermoplastic resin sheet adheres sufficiently to the back surface of the tile and at the same time enters into the groove on the back surface of the tile, so construction is performed with the thermoplastic resin sheet covering the back surface of the floor tile. Even in such a case, a fixing agent such as an adhesive can enter the back grooves, and each floor tile can be firmly fixed to the base.

[Fourth solution] The fourth solution of the present application is also related to a method for manufacturing a floor tile unit, and its gist is to place a plurality of floor tiles upside down on the tile support surface of a holding formwork. While arranging them in a predetermined arrangement, a thermoplastic resin sheet was placed to cover the back surfaces of the floor tiles and then heated and softened, or a thermoplastic resin sheet that had been heated and softened in advance was placed on the back surfaces of the floor tiles. After that, the joint part is pushed into the gap between each tile from the back side of the tile, and a part of the thermoplastic resin sheet is pushed into the gap between the tiles, and at the same time, it is formed to cover the joint part, and together with this, By suctioning the thermoplastic resin sheet from the tile surface side through the suction recesses formed in the holding formwork and through the gaps between the tiles, the softened thermoplastic resin sheet is brought into close contact with the back surface of each floor tile. The purpose is to connect the floor tiles to each other.

[Operations and effects of the fourth solution] According to this method, a joint consisting of a joint and a part of a thermoplastic resin sheet covering the joint can be extremely easily formed between tiles. can.
