Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing exterior wall tiles used for, for example, vertical walls or ceiling walls of buildings.

To install the above-mentioned exterior wall tiles, the concrete is generally poured and attached to the wall using mortar as an adhesive, but this has the disadvantage that the tiles tend to peel off due to a decline in adhesive strength over time. .

Therefore, as shown in Japanese Utility Model Publication No. 55-174430, in the past, a deep and widening hole was formed on the back side of the tile, mortar was inserted into the hole and solidified, and the solidified mortar caused the connection. It is proposed that it be stopped.

However, in order to form the holes, combustible solids are provided in the tile raw material and fired, and the solids are burned and removed as the tile raw material is fired. Therefore, a large number of solid objects of special materials are required and are expensive, and furthermore, it requires a great deal of effort to install the solid objects into the tile raw material, which has the disadvantage of making the method even more expensive. .

In addition, because of the deep-spreading hole, it was difficult to fill the hole with mortar sufficiently when pouring concrete, and even though the cut angle was widened deep, sufficient locking force could not be obtained.

SUMMARY OF THE INVENTION In view of the above points, it is an object of the present invention to make it possible to inexpensively form a deep-widening hole in a tile, and to enable the tile to be sufficiently fixed and attached to a wall.

In order to achieve the above object, the method for manufacturing tiles for exterior walls according to the present invention includes accommodating a tile raw material in a recess formed in a mold, press-molding the tile raw material using a press mold provided with an elastic protrusion, and With pressing, the elastic protrusion is elastically expanded and deformed in a direction perpendicular to the pressing direction, and a deep expanding hole is formed on one side of the molded tile by separating the pressing mold,
The molded tile is removed from the mold and fired, and then an anchor member is fitted into the hole and integrated with a solidifying agent.

In other words, with pressing, the elastic protrusions receive compressive force and are pushed out in the direction of the surface of the tile.Moreover, as the press die is separated, the part that is pushed out and spread out naturally contracts in the direction of the surface of the tile due to the elastic restoring force. ,
This allows a deep, widening hole to be formed without increasing the width of the entrance.

Therefore, there is no need to use solid materials that are consumed during firing, and there is no need to take the trouble of installing them in the tile raw material.Just by equipping the press mold with elastic protrusions, the process can be completed in the same way as usual. It is now possible to form deep and wide holes in tiles at low cost by simply performing press work and firing.

Moreover, since the anchor member, such as the anchor bolt or the female threaded hardware for attaching the anchor bolt, is integrated into the hole in advance with a solidifying agent, the solidifying agent can be sufficiently filled into the hole and integrated. When integrating with the wall, the tiles are integrated with anchor bolts that are integrated directly with the tile or through female threaded metal fittings, and the tile is firmly integrated into the concrete, preventing it from peeling off over time. We are now able to effectively prevent this.

Examples of the method of the present invention will be described below with reference to the drawings.

Powder-like or clay-like tile raw material A is accommodated in a recess 2 formed in a fixed mold 1. (See A in Fig. 1) Press die 3 is inserted into recess 2.
The tile raw material A is pressed, solidified, and molded. (See Figure 1, B) On the pressing surface side of the press die 3,
Bar-shaped elastic protrusions 4, 4 are integrally attached and distributed in the plane direction, and are adapted to be expanded within the tile raw material A in a direction perpendicular to the pressing direction as a result of the above-mentioned pressing.

The press die 3 is separated from the fixed die 1, and the elastic protrusions 4, 4 are detached accordingly.
Molded tile B with deep and wide holes 5, 5 formed
get. (See C in FIG. 1) The molded tile B is removed from the fixed mold 1 (see D in FIG. 1), and then fired.

As shown in FIG. 2, female screw hardware 6 is inserted into each of the holes 5 and 5 of the fired molded tile B, and non-shrinkage mortar C (Denka Tascon Mortar: trade name, Denki Kagaku Kogyo Co., Ltd.) is inserted into the holes 5 and 5, respectively. company)
The female threaded metal fittings 6, 6 are integrated into the molded tile B to obtain an exterior wall tile 7.

When installing the exterior wall tile 7 on a ceiling wall 8 or a vertical wall, as shown in FIG.
Anchor bolts 9 are screwed to each, and the tip hooks 9a of the anchor bolts 9 are attached to reinforcing bars (not shown).
The tiles 7 are integrated into the concrete ceiling wall 8 by hanging them on the tiles and pouring concrete.

As the elastic protrusion 4, various materials such as hard urethane rubber are used.

In addition, as the elastic protrusion 4, for example, as shown in FIG.
1 or a cut groove 12 may be inserted so that it can easily expand in a direction perpendicular to the direction of the pressing as it is pressed.

For press-molding the tile raw material A, the mold 1 and the press mold 3 are not limited to metal, and may be made of hard resin or the like.

In the above embodiment, the molded tile B has a female threaded hardware 6.
The anchor bolts 9 can be attached to the anchor bolts 9 on-site, so that a large number of external wall tiles 7 can be stacked and transported to the site with a low volume. 9. To save installation time after...
The anchor bolt 9 may be inserted into the hole 5 and directly integrated, or the anchor member 6,
Collectively referred to as 9.

In addition, the anchor members 6 and 9 are attached to the outer wall tiles 7.
In order to integrate the solidifying agent C, not only the non-shrinking mortar C but also various other materials such as epoxy resin can be used, and these are collectively referred to as the solidifying agent C.

In addition, the above-mentioned exterior wall tiles mainly include:
The present invention is applied to so-called ceramic plates of sizes such as 300 x 450 (mm) and 600 x 600 (mm), but the present invention is not limited to these sizes.
