Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tile unit used in implementing a tile tipping method.

Conventionally, as a tile unit, the surfaces of a group of tiles arranged in a rectangular shape with a desired joint gap between the tiles are covered with a tile connecting sheet, and the tile connecting sheet is plastically deformed to form a λ-shape. It is known that protrusions are made to protrude from the outer edge of two adjacent sides of the group of rectangular tiles and from the joint gap between the tiles. Adjacent shape tile group 2
After forming a tile unit in which tile connecting sheet extensions are extended outward from the outer edge of the base of the milky protrusion formed on the outer side of the side and the other two adjacent sides of the quadrangular tile group. The tile unit was obtained by cutting with a cutter or the like along the boundary between the sheet extension and the milky convexity and the boundary between the sheet extension and the other two adjacent sides of the tile group.

However, the cutter often damages the tile along the boundary between the sheet extension and the milky protrusion and the boundary between the sheet extension and the other two adjacent sides of the tile group, and the cutter blade breaks. It requires skill to cut without causing damage, and it is particularly difficult to cut quickly and accurately with a cutter or the like along the boundary between the sheet extension and the extremely easily deformable pile-like protrusion. The tile unit had the drawback of requiring a long time to manufacture and resulting in a tile unit with poor external dimensional accuracy.

The present invention aims to provide a tile unit that overcomes the above-mentioned drawbacks.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 shows an embodiment of a tile unit according to the present invention,
This is an intermediate omitted plan view viewed from the back side of the tile, and 1 in the figure is a tile group, and the tile group 1 is a tile group 2, 2, and 2.
...They are arranged in a rectangular shape with desired joint gaps 3, 3... between them.

Reference numeral 4 denotes a tile connecting sheet made of a thermoplastic synthetic resin with four adhesive agents added thereto. An eave-like protrusion 4a that temporarily fixes the tile group 1 by its own adhesive force and is formed not higher than the thickness and height of the tile 2 by plastic deformation of the tile connecting sheet 4.
, two adjacent sides 1 a s 1 of the quadrangular tile group 1
protrude toward the outside of the tiles 2, 2... and into the joint gap 3.3... between the tiles 2, 2... and the tile group 1.
An eave-like protrusion 4 formed on the outer side of two adjacent sides 1a and la
The outer edge of the root part of a + a' and the quadrangular tile group 1
Tile connecting sheet extensions 4b, 4b, . . . extend outward from the other two adjacent sides lb, lb.

As shown in FIGS. 2 and 3, the tile connecting sheet 4 is torn along the row-like projections 4a at the boundary between the tile connecting sheet extension 4b and the eave-like projections 4a. A cutout groove 5 having an appropriate shape such as a Y-shaped cross section is provided at the boundary between the tile connecting sheet extension 4b and the other two adjacent sides lb, lb of the tile group 1. Cutout grooves 5 are formed along two sides lb, lb to facilitate tearing of the tile connecting sheet 4.

Next, a method for manufacturing a tile unit according to the present invention will be explained.

As shown in FIG. 4A, an elastic rectangular tile arrangement plate 8 made of silicone rubber or the like having an appropriate hardness is placed on the surface plate 6, and the outside of the tile arrangement plate 8 is placed on the surface plate 6. An outer frame 7 is fixed on the surface plate 6 so as to surround the side surface.

The outer frame 7 has an inverted V-shaped protrusion 7a on the inner edge of the upper surface.
The tip of the protrusion 7a protrudes so that it is approximately at the same height as the upper surface 2a of the tile 2 inserted into the tile insertion hole 8a of the tile arrangement plate-like body 8.

On two adjacent sides of the tile arrangement plate-like body 8, joint grids 8b are formed to form the first openings 8a for tile insertion, and on the other two adjacent sides, joint grids 8b are formed. The inner surface 7a of the outer frame 7 forms a tile insertion recess 8c.

Tile insertion squares 8a of the tile arrangement plate-like body 8
z 8 a... and tile insertion recesses 8c, 8c
... are opened with holes 10, 10, ... for suction and deaeration.

First, the tile insertion squares 8a, 8a, . . . and the tile insertion recesses 8c of the tile arrangement plate-like body 8.

Insert the tiles 2, 2... with the surface 2a facing upward into the space 8c to create a desired joint gap 3.3.
. . . to obtain a group of tiles 1 arranged in a rectangular shape.

Next, the tile connecting sheet 4 is placed so as to cover the upper surface of the tile group 1 and the upper surface of the outer frame 7.

Subsequently, the tile connecting sheet 4 is heated (for example, 15
After heating for 1 minute in a heating oven at 0°C,
As shown in FIG.
/cvi for 30 seconds), the holes 10, 10.
By degassing through..., the tile connecting sheet 6 is brought into close contact with the surface of the tiles 2, 2..., and
Due to the plastic deformation of the tile connecting sheet 4, protrusions 4a which are not as high as the thickness of the tiles 2 are made to protrude into the outer edges and joint gaps 3 of the two adjacent sides of the quadrangular tile group 1.

Due to the suppression of the suppression plate 11, the elastic tile arrangement plate 8 is slightly compressed through the tiles 2, 2..., and the surfaces of the tiles 2, 2... are slightly lowered in height, and as a result, Since the tip of the protrusion 7a of the outer frame 7 is slightly higher than the surface of the tile 2, the notch groove 5 is formed in the tile connecting sheet 4 by the pressure between the protrusion 7a of the outer frame 7 and the pressing plate 11. .

Finally, after cooling the tile connecting sheet 4, the pressing plate 1
1 is released, and the tile unit 12 (see FIGS. 1 to 3) is obtained by detaching it from the tile arrangement plate 8.

The obtained tile unit 12 is torn along the notch groove 5 at the time of factory shipment or during on-site construction, and the root portion 4a' of the eave-like protrusion 4a formed on the two adjacent sides 1a, la of the tile group 1. The outer end face and the end faces of the tile connecting sheet 4 along the other two adjacent sides lb, lb both have irregular torn end faces, resulting in a tile unit (not shown) suitable for construction.

As described in detail above, the tile unit according to the present invention can quickly provide a tile unit with high external dimensional accuracy suitable for construction by simply tearing it along the notch groove, and has a low manufacturing cost. It has an excellent advantage of being able to provide tile units.
