Abstract

PURPOSE:To form a recessed part contracting on its inlet side to the rear of a architectural material in order to enhance the adhesion to a surface to be executed in molding the architectural material by swage-molding or cast- molding. CONSTITUTION:In swage-molding, a water impermeable soft sheet 4 having a large number of hollow projections or ridges is laid on the surface of the body plastic material 3 in a mod to apply pressure molding to the material 3. In cast-molding, the sheet is laid on the self-curable slurry on the bottom surface of the mold or within the mold to cure the slurry. The projections or ridges of the sheet are deformed so as to become thick at the tips there of at the time of molding. Since recessed holes contracting on the inlet side thereof are formed to the rear of the building material, the adhesion and execution properties are enhanced. When a tile is bonded to the panel thus molded, a tiled bonded panel having extremely high tile bonding strength can be produced.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embossing method and a casting method for building materials and a method for manufacturing a tiled panel. Specifically, when molding a building material by an embossing molding method or a casting molding method, for improving the adhesiveness to the construction surface on the back surface of the building material, by forming a recessed hole or recessed groove on the inlet side, The present invention relates to a method for molding a building material with improved workability and a method for manufacturing a tiled panel using a panel molded by this method.

[0002]

2. Description of the Related Art Conventionally, as a molding method for building materials such as tiles,
An embossing molding method in which a kneaded clay-plastic body is pushed into a forming die and the kneaded clay-plastic body in the forming die is pressed, or a self-hardening slurry is poured into the forming die and the self-hardening slurry is poured in the forming die. A casting method is known. Among these methods, the embossing molding method is particularly used for molding a building material having a relief pattern on the surface.

As a conventional method for producing a tiled panel, there is a method in which the tiles are arranged inside out in a flat plate-like form and turned upside down, and mortar or concrete is placed on the tile to cure it, and then the mold is removed. is there. In addition, tiles may be attached to the panel via mortar. in this case,
Poor adhesion between the mortar and the panel results in tile peeling.

Construction of building materials such as tiles is usually carried out by applying a base mortar to the construction surface and pressing a building material such as tiles with the attached mortar on the back surface against the base mortar. Also, omit the base mortar,
Building materials such as tiles can also be directly attached to the construction surface using only mortar.

In the above-mentioned conventional construction method, if the adhesiveness between the mortar and the building material such as tiles is not sufficiently obtained, the building material such as tiles easily peels off from the construction surface, resulting in a falling accident. ..

Conventionally, in order to improve the adhesion between building materials such as tiles and the adhesive mortar, and prevent falling accidents, the back surface of building materials such as tiles is roughened, and irregularities such as dovetail holes and dovetail grooves are provided. The method of doing is proposed.

[0007]

However, a sufficient effect of improving the adhesiveness cannot be obtained only by roughening the back surface of the building material such as tiles. Adhesiveness is slightly improved by providing unevenness on the back surface, but sufficient adhesion cannot be obtained by simple unevenness. On the other hand, by forming a recessed recessed hole (or groove) on the back side of a building material such as a tile, the adhesive force between the mortar and the building material such as a tile can be significantly increased. .. That is, if it is a recessed concave hole on the inlet side, the hardened adhesive mortar will firmly adhere to the concave hole in an anchor shape, and the adhesive force between the building material such as tiles and the adhesive mortar will be remarkably high. Become.

However, in the conventional embossing molding method and cast molding method, there has not been proposed an efficient molding method capable of forming a recessed recessed hole on the back side of a building material such as a tile. , Its development is desired.

The present invention has been made in view of the above-mentioned conventional circumstances, and in molding a building material by an embossing molding method or a casting molding method, an inlet for improving adhesion to a construction surface on the back surface of the building material. An object of the present invention is to provide a method for forming a building material with improved workability by forming a recessed hole on the side.

Another object of the present invention is to provide a method of manufacturing tiles in which tiles and panels are firmly joined.

[0011]

A method for embossing a building material according to claim 1, wherein a building material is molded by pushing a plastic body into a molding die and pressing the plastic body in the molding die. In, the non-water-absorbent soft sheet having a large number of projections or ridges (hereinafter, may be simply referred to as "soft sheet") is pressed against the surface of the plastic body in the molding die to form the projections or ridges. Is deformed into a thickened tip to form a concave hole or groove on the back surface of the building material, the concave side of which is narrowed on the inlet side.

A non-water-absorbent soft sheet having the above is provided on the mold surface in advance in the molding die, and the protrusion or the ridge is deformed into a thickened shape by the fluid pressure of the self-hardening slurry, so that the inlet side has a recess on the back surface of the building material. It is characterized by forming a recessed hole or groove.

The method for manufacturing a tiled panel according to claim 3 is
A panel is formed by the method according to claim 1 or 2, and a tile is attached to the surface of the panel having a recessed hole or a recessed groove by mortar.

[0014]

In the embossing method for a building material according to the present invention, a soft sheet made of rubber or synthetic resin having a large number of protrusions or ridges is formed on the surface of the clay-plastic body in the molding die (this surface is By pressing against the back surface) and molding, the back surface of the obtained building material has irregularities derived from the projections or ridges of the soft sheet. Similarly, in the casting method of building materials, by providing a non-water-absorbent soft sheet having a large number of projections or ridges on the mold surface in the molding die in advance, the back surface of the obtained building material is formed on the surface. The abutting surface has irregularities derived from the projections or ridges of the soft sheet.

In the present invention, as the plastic body, in addition to the kneaded clay plastic body, hard-mixed mortar, concrete, gypsum,
Examples thereof include calcium silicate. Examples of the self-hardening slurry include mortar, concrete, gypsum, calcium silicate, and the like.

In this case, the projections or ridges 11a of the soft sheet 11 shown in FIG. 3 are changed to the state shown in FIG. As shown, it receives pressure A and expands and deforms into a tapered flat shape, and in this state the clay-plastic body or the self-hardening slurry 12 is molded, so as shown in FIG.
On the back surface of the obtained building material 13, a dovetail-shaped recess, that is, a recessed hole or groove 13a that is narrowed on the inlet side is formed.

Since the dovetail-shaped recessed hole or groove having the recessed inlet side is joined to the mortar 14 like an anchor as shown in FIG. 6, the adhesiveness is extremely high. Since the soft sheet 11 used here is a non-water absorbent material,
The releasability (release property) from the obtained building material 13 is also good.

When mortar is used to attach a tile to the surface of the panel having the dovetail-shaped recessed hole or groove formed with the recessed hole or groove, the mortar adheres strongly to the panel. Therefore, a tiled panel with extremely high tile strength is manufactured.

The present invention is also suitable as a method for manufacturing a PC panel.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of an embossing method for a building material of the present invention, and FIG. 2 is a sectional view showing an embodiment of an injection molding method for a building material of the present invention.

In the die-press molding method shown in FIG. 1, the kneaded clay plastic body 3 is pushed into the female die 2A on the fixed base 1 in which the relief pattern-shaped irregularities are formed on the inner bottom surface of the die. On the other hand, the soft sheet 4 having a large number of hollow projections or ridges is laid on the mold surface of the male mold 2B attached to the movable table 5, and the movable table 5 is lowered to move the soft sheet 4 to the female mold 2A. It is pressed against the surface of the kneaded clay-plastic body 3 to be molded, and then demolded.
During this demolding, the soft sheet 4 is a non-water-absorbing material, so that the soft sheet 4 is easily peeled off from the molded body. Of course, there is no possibility of damaging a portion near the recessed hole or the recessed groove described below.

As a result, a large number of hollow projections or ridges of the soft sheet are pressed by the embossing pressure, as shown in FIG.
On the back surface of the resulting building material that spreads to the tip, a recessed hole or a recessed line is formed as shown in FIG.

In the casting method shown in FIG. 2,
A soft sheet 4 having a large number of hollow projections or ridges is laid on the bottom surface of the mold 6 in advance, and then a self-hardening slurry is poured into the mold to mold it, and the mold is removed after curing. Even during this mold release, since the soft sheet 4 is a non-water absorbent material, the soft sheet 4 is easily peeled off from the molded body. Of course, there is no possibility of damaging a portion near the recessed hole or the recessed groove described below.

Also according to the method of this embodiment, the projections or ridges of the soft sheet are moved to the fourth position by the fluid pressure of the self-hardening slurry.
As shown in the figure, a concave hole or groove is formed on the back surface of the resulting building material, which is widened toward the tip and is narrowed on the inlet side as shown in FIG.

It should be noted that in FIGS. 1 and 2, the holes of the projections or ridges of the soft sheet 4 are not shown, but in reality the projections or ridges 11a of the soft sheet 11 of FIG. Similar holes are provided.

In the present invention, the soft sheet having projections or ridges to be used is not particularly limited in shape, size, number of projections per unit area, etc. of the projections or ridges. Is appropriately selected so that the adhesive strength of is sufficiently obtained. For example, in addition to the soft sheet 15 having the protrusion 15a shown in FIG. 7, the soft sheet 16 having the protrusion 16a shown in FIG. 8 can be used. Also,
The protrusions or ridges may be solid. The protrusions and ridges of the soft sheet may have a tapered flat shape from the beginning (that is, even if the fluid pressure of the self-hardening slurry is not applied).

Although the present invention can suitably manufacture a tile by the method as in the above-mentioned embodiment, the present invention is also suitable for manufacturing a panel which is a substrate to which the tile is attached.

That is, a panel having a dovetail-shaped concave hole or groove on at least one plate surface is formed by the above method. Then, the tile is attached to the surface having the concave hole or the concave line with mortar. Then, as shown in FIG. 9, the mortar 23 is inserted into the dovetail-shaped recess or recess to obtain a tiled panel 22 in which the tiles 21 are firmly attached to the plate surface of the panel 20. in this case,
The tile 21 itself may have a dovetail-shaped recess formed on the back surface by the embossing molding method or the casting method of the present invention. This tiled panel is usually fixed to the frame by suitable fittings such as bolts. In this case, the bolt may be planted in the panel 20 as an anchor bolt.

The panel 20 as the substrate may be a hollow panel 31 having a cavity 30 as shown in FIG.
To manufacture this hollow panel 31, a soft sheet is laid on the bottom of a shallow mold, and a rod-shaped core material is horizontally installed at a position slightly raised from the bottom. Then, concrete, mortar, or the like is poured in, and the mold is removed when the hardening has progressed to some extent. At this time, the core material is also pulled out. As a result, the hollow panel 31 having a dovetail-shaped recess on one plate surface is manufactured. In this case, embedding a strained prestressed steel material produces a prestressed panel. Although the cavity 30 has an elliptical shape in FIG. 10, it may have various shapes such as a perfect circle. Instead of pouring concrete or mortar, a plastic body may be pushed in and a soft sheet having a large number of protrusions or ridges may be pressed against the surface of the plastic body.
