Description

[Detailed explanation of the idea] This invention relates to a tile base for internal baseboards.

Inner width water is a type of accessory for flat tiles,
Tile base (hereinafter abbreviated as base).

Furthermore, the term "base material" includes green material and unglazed material.

) is curved in a concave arc toward the glazed surface, and its types include inner width water, inner baseboard corner, inner baseboard single-sided corner, inner baseboard single-bevel, etc. (JIS A 520
(See 9 ceramic tiles and 1 porcelain tiles).

Conventionally, when base materials for inner baseboards were glazed and then packed into saggers and fired, there were the above-mentioned drawbacks.

Hereinafter, an explanation will be given based on FIG. 1, taking as an example the case of manufacturing a book of inner width.

Made of ceramic, cement, 9-ply resin. A base material 1 for an inner skirting board made of metal or the like is composed of a flat part 2 and a curved part 3 that is curved at nearly 90 degrees with respect to the flat part 2 and connected to one side of the flat part 2.

In this specification, a curved portion includes a curved portion having a flat portion at its tip.

The base material 1 has a surface 4 after being bisque fired or as it is.
The glaze 5 is placed on the conveyor with the surface facing upward, and the glaze 5 is uniformly and automatically applied to the surface 4 and the tip surface 3a of the curved portion 3 while being moved on the conveyor.

Next, the glaze 5 adhering to the tip surface 3a of the curved portion 3 is wiped off with a roller or the like, and the glazed surface (surface) 4 of each of the two substrates 1 is removed.
They are placed in a pair so that they face each other and the tip surfaces 3a of the curved portions 3 are butted against each other, and are housed in a sagger and fired.

As mentioned above, the glaze 5 on the front end surface 3a of the curved portion 3 is wiped off when the glaze 5 is attached to the front end surface 3a, and the glaze 5 straddles the front end surface 3a due to the action of surface tension. Since the pixel base 1 is fired in such a state, the fired glaze 5 causes the pixel base 1 to become connected at the tip surface 3a, and therefore, the fired multi-pixel base 1 must be separated, but at that time, the glaze in the connected state may be damaged. This is because the glaze 5 often extends to the glaze 5 layer of the curved portion 3.

However, the wiping of the glaze 5 on the tip surface 3a by a roller or the like is not always done completely, and is sometimes incomplete, and a small amount of the glaze 5 remains on the tip surface 3a, resulting in the above-mentioned situation. , there were many cases in which comrades with 1 base were connected.

The same thing can be said about the inner width of the inner baseboard corner.

This invention was made to solve the above-mentioned drawbacks.

This invention will be explained below according to embodiments shown in the drawings.

In FIGS. 2 to 4, the same members as those in FIG. 1 are designated by the same reference numerals as shown in FIG.

Made of ceramic, cement, 5-ply resin. A glaze 5 applied to the base 1 is applied to the tip surface 3a of the curved portion 3 of the base 1 made of metal or the like.
A pair of small protrusions 6, 6 protruding slightly larger than twice the thickness of the layer are integrally formed.

For example, if the thickness of the glaze 5 layer is 0°23 mm,
The height of the small protrusions 6, 6 is approximately 0.5 mm.

The center line C1 between these small protrusions 6, 6 deviates from the center line C2 that symmetrically divides the substrate 1 into two by a value larger than half of the width W of the small protrusions 6, 6. ing.

This is to prevent the small protrusions 6, 6 from coming into contact with each other when the tip surfaces 3a of the curved portions 3 of the two base materials 1 are butted against each other.

However, the rain center line CI appears as if the small bumps 6 and 6 are hitting each other.
.

In some cases, C2 may be matched.

In such a case, the height of the small protrusions 6 only needs to be greater than the thickness of the glaze 5 layer.

The tile blank 1 of this example is fired in the same manner as conventional tile blanks.

FIG. 5 shows an embodiment in which the present invention is applied to an inner baseboard corner, in which a pair of small protrusions 16.16 are formed on the tip surface 13a of the curved portion 13 on one side of the flat portion 12 of the base material 11. It is integrally formed.

FIG. 6 shows an embodiment in which the present invention is applied to a single chamfer of an inner skirting board, and shows the tip surface 23 of the curved portion 23 of the base material 21.
A pair of small protrusions 26, 26 are integrally formed on a.

FIG. 7 shows an embodiment in which the present invention is applied to a single-sided corner of an inner skirting board.
A pair of small protrusions 36, 36 are integrally formed on the.

The number of small protrusions is not limited to two, and may be one or three or more.

However, when providing two or more small protrusions, there is an advantage that at least one small protrusion can be reliably formed as long as all of the holes for small protrusions in the mold are not clogged. Even if one of the base materials used is a conventional product, there is an advantage that the gap between the tips of the curved portions of both can be kept uniform.

According to the above, according to this invention, at least one small protrusion is formed on the tip surface of the curved part of the base material, so that after the base material is glazed, the glazed surfaces of the pair of base materials are used for firing. When the two curved portions face each other and the tip surfaces of the curved portions butt each other, a gap is created between the tip surfaces.
Even if glaze remains on the tip surface, it is effective in preventing the glaze from contacting the other tip surface or from contacting each other.

Therefore, it is possible to eliminate the drawback mentioned at the beginning, that is, the pixel base is baked due to the glaze existing between the tip surfaces of the curved part, and when they are separated, the glaze layer on the curved part is damaged. I can do it.

Furthermore, even if the small protrusion comes into contact with the glaze remaining at the tip of the other curved part, since it is a small protrusion, the contact area is extremely small, so even if the pixel base is baked, it is easy to separate both Since it can be separated into two parts, the glaze layer on the curved part will not be damaged.
