Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tile unit in which the back surfaces of a large number of tiles arranged vertically and horizontally with predetermined joint gaps are connected by connecting paper.

(Prior art and its problems) Conventional tile units include those shown in FIGS. 1 and 2.

In conventional example 1 shown in FIG.
However, since the connecting paper 2 covers the central part of the back surface of the tile 1, the effective bonding area of the adhesive for attaching the tiles is reduced.

Furthermore, in the conventional example 2 shown in FIG. 2, four tape-shaped connecting sheets 3 are used, but the width of the opening 4 provided in each connecting sheet 3 is larger than the joint width, and both sides of the opening 4 are (A-A in Fig. 2)
In Fig. 3, which is a line cross-sectional view, the widths of 5a and 5b) are small, so when the tile units are stacked and packed, there is a risk that each tile unit will stick together due to the glue protruding from the connecting paper 3. Since the sheets 3 are separated, it is troublesome to paste them manually, and an automatic pasting device is required.

(Purpose of the invention) The object of the invention is to provide a tile unit that does not have the drawbacks and problems of the conventional example.

(Structural features of the invention) A structural feature of the tile unit of the invention is that the back surfaces of a large number of tiles arranged vertically and horizontally with predetermined joint gaps are placed in contact with the joints of two adjacent tiles. The point is that the vertical and horizontal strips are connected by a single sheet of connecting paper in which openings each have a width approximately equal to the joint width.

(Explanation of Embodiment) In Embodiment 1 shown in FIG. 4, all vertical and horizontal strips 8 and 9 corresponding to the joints of two adjacent tiles of the integrally molded connecting paper 7 are provided with approximately the same width as the joints of the tiles. Openings 10 of equal width are provided, and at the intersection of the strips 8 and 9, an opening 11 is provided with an area larger than the area occupied by the joints at the corners of the four tiles.

Two adjacent tiles are mainly connected to the connecting paper 7.
The openings 10 and 10 of the tiles are connected via a connecting part 12, but both sides of each opening 10 also contribute to the connection, and the connecting paper 7 has a portion that does not contribute to the connection between the tiles. (Note that in the case of Conventional Example 2, the tile pasting portions 5b of the connecting sheets 3 on both sides do not contribute to connecting the tiles).

By appropriately determining the length and number of the openings 10, the length and number of the connecting portions 12 are determined. From the viewpoint of construction, it is desirable that the length of the openings 10 be as long as possible, but the weight of the tile and the connection The length and number of the openings 10 are determined according to the desired strength of the connecting portion 12 in consideration of the material strength of the paper 7.

In Example 1, the tile 1A is connected to two sides, the tile 1B is connected to three sides, and the tile 1C is connected to four sides, so the strength of the connection is uneven.
By improving this point, tiles 1B and 1C are changed to tile 1
Embodiment 2 shown in FIG. 6 is designed to connect with the same strength as A.

In the connecting paper 13 used in Example 2, the band-shaped parts 8 and 9 that connect the four circumferences of the tiles 1C in the connecting paper 7 used in Example 1 are replaced with connecting parts 14 and 15 that are not tile connecting paper. has been
The tile 1C is connected to a portion 16 of the connecting paper 13 where the corners of the four tiles contact.

In Embodiment 3 shown in FIG.
is provided, but the rest is the same as in the second embodiment.

(Effects of the invention) The tile unit of the invention is connected by a connecting paper having a shape that has a minimum area for connecting the tiles, and moreover, the effective adhesion area during pasting is large. In particular, by making the width of the opening provided in the strip of connecting paper approximately equal to the joint width, the width of the tile pasting portions 5 on both sides of the opening is large, which is different from that in Conventional Example 2 described above. This not only prevents accidents in which the tile units stick together due to the glue protruding from the connecting paper, but also because the connecting paper is a single sheet, it can be easily attached by hand and manufacturing is easy.
