[0003]

In the conventional tile unit, since the paper tape absorbs the water content of the tile adhesive used at the time of construction, the tensile strength of the paper tape is reduced.
Not suitable for heavy exterior tiles. Furthermore, in the manufacture of tile units, it is necessary to apply a water-resistant adhesive to the entire surface of one side of the paper tape in advance and to bond the paper tape to the back side edge of the tile before the water-resistant adhesive dries, and to dry the water-resistant adhesive. There is. Therefore, a lot of labor is required for manufacturing the tile unit, and there is a problem that productivity is poor.

Therefore, an object of the present invention is to provide a tile unit which can be applied to heavy exterior tiles by strengthening the connection strength between the tiles. Another object of the present invention is to provide the production of a tile unit which can improve the productivity of the tile unit having excellent adhesiveness to a joint agent.

[0005]

The gist of the present invention according to claim 1 is that the back surface of a tile group in which a plurality of tiles are arranged with a joint gap is arranged, and the joint gap is provided between the rear side edges of adjacent tiles. In the tile unit connected by a tape that is joined across the tile unit, a base material of the tape is formed of a synthetic resin sheet, which is a tile unit. Since the base material of the tape is molded from a synthetic resin sheet, it has a higher tensile strength than paper of the same thickness and is more water resistant, so the tensile strength depends on the water content in the tile adhesive during construction. It does not decrease. Therefore, the present invention can be applied to heavy exterior tiles.

According to a second aspect of the present invention, in the tape, the joining is performed with an adhesive and a non-adhesive area having no adhesive layer is formed in a portion straddling the joint gap.
It is the described tile unit. In general, the compatibility of the joint between the joint agent and the adhesive layer is poor, but in the present invention, since the portion that straddles the joint gap is a non-adhesive area, the adhesiveness between the tape portion located in the joint gap and the joint agent is Can be good. Even when the joint agent is not applied, dust or the like does not adhere to the non-adhesive area of the tape forming the joint gap.

The gist of the present invention according to claim 3 is the tile unit according to claim 1 or 2, wherein the tape is provided with a large number of through-holes in a portion straddling the joint gap. When applying, the tile adhesive passes through a large number of through holes of the tape portion located in the joint gap and goes out to the surface of the tape portion, so that the tile adhesive acts as a joint agent to form the joint portion. Therefore, according to the present invention, it is possible to obtain a clean joint portion in which the joint gap having the tape and the joint gap having no tape are formed by the same tile adhesive.

According to a fourth aspect of the present invention, a tile group is formed by arranging a plurality of tiles with a joint gap provided therebetween.
In a method for manufacturing a tile unit in which a tape straddling a joint gap is joined to the back side edges of adjacent tiles to connect tile groups, in the tape, an adhesive layer is formed on both side edges of a synthetic resin sheet and a joint gap is formed. A method of manufacturing a tile unit, characterized in that an adhesive tape having a non-adhesive area without an adhesive layer is used in a central area corresponding to a portion that straddles. According to the present invention, adjacent tiles can be immediately connected to each other only by joining an adhesive tape to a tile group in which a plurality of tiles are arranged, and productivity can be improved.
Further, in the present invention, since the tape portion straddling the joint gap is the non-adhesive region, it is possible to manufacture a tile unit in which the adhesiveness between the tape portion located in the joint gap and the joint agent is good.

A fifth aspect of the present invention is the method for manufacturing a tile unit according to the fourth aspect, wherein a large number of through holes are provided in the central region of the adhesive tape. According to the present invention, the tile unit having a large number of through holes in the tape portion located in the joint gap can be easily manufactured.
