Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile repairing method and an anchor plate therefor.

[0002]

2. Description of the Related Art For example, in the case of a building in which the outer wall is tiled, there is a danger that the tile will float over time and fall off. In order to prevent this, the floating portion must be repaired.

[0003] As a method of repairing the floating portion of the tile, there is a method of shaving the tile in the floating state and re-stretching the tile, or a method of making a pin driving hole through the tile itself and opening it from the outside. There are two known methods: a method in which an anchor pin is driven into the interior of the base mortar.

[0004]

However, in the former method, not only the tiles but also the joints need to be cut off, so that the number of steps is very large, heavy labor is required, and the workability on site is poor. In addition, the chipping work tends to cause chipping or cracking of the tiles, so it is necessary to prepare the new tiles for firing, and it is difficult to unify the color and gloss of the old and new tiles. And hinders the appearance cosmetic effect of the tiled state.

[0005] On the other hand, in the latter method, it is not necessary to cut off even the joints of the tiles, but it is difficult to quickly and accurately form a pin driving hole in the hard tile itself.
Since the tile is inevitably damaged in the drilling operation by the drill, the same problem as the former method is brought.

As a solution to such problems, the present applicant has previously proposed Japanese Patent Application No. 9-161990, but as a result of intensive research, the present invention has a floating tile with a certain depth. It is a method to cut the slit of
In addition, since anchor pins are driven into joints of tiles, if the tiles are mosaic tiles or other small items, they will not be damaged yet and they can be driven into narrow joints. It turned out to be difficult, especially for small tiles.

[0007]

SUMMARY OF THE INVENTION The present invention aims to further improve such a problem, and as a tile repair method useful for this purpose, a slit having a fixed opening length adjacent to a floating tile is provided at the joint thereof. Cut into the base mortar as a constant depth to reach the inside, and insert an anchor plate to be the sole of the floating tile inside the slit, and insert the anchor plate only to the floating tile or to both the floating tile and the joint, It is characterized by being fixed and integrated with an adhesive,

Further, the anchor plate used in the above-mentioned repairing method is composed of a stainless steel plate, a fiber-reinforced synthetic resin plate having a fixed depth reaching the inside of the base mortar, or other non-rusting plate material because of its structure. A plurality of ridges and recesses are arranged in a row along the depth direction.

The width (W) of the anchor plate (A) is, for example, about 1.8 mm, and the joint width (W) of the tile (T) is set.
The depth (D) is also made smaller than that of 1), and the depth (D) is, for example, about twice as large as the thickness of the tile (T), and is inserted into the interior of the base mortar (M) to use the tile (T). So that it can function as a sole.

FIGS. 2 to 4 show first to third modified embodiments of the anchor plate (A). The anchor plate (A) is made of fiber reinforced resin (FRP) or another material instead of a stainless steel plate. A plurality of ridges (11) and valleys (12) parallel to each other along the depth direction as shown in FIG. 2 may be arranged by extruding a plate material that does not rust.

As shown in FIG. 3, the ridges (11) and the ridges (12) are arranged only on one surface of the anchor plate (A), and a plurality of adhesive flow holes (14) are formed. The punching openings may be distributed.

Further, the number of groups of the projections (15) as shown in FIG. 4 is scattered and distributed on the surface of the anchor plate (A), and together with the depressions which are relatively depressed therewith, the whole is obtained. Even if the surface is roughened.

According to the anchor plate (A) of the above-described basic embodiment and the first to third modified embodiments, the adhesive (13) is effectively adhered and integrated with the anchor plate (A) based on the large frictional force of the entire surface. It is possible to obtain high fixing strength with the tile (T), the joint (B), and the base mortar (M). The tip of the anchor plate (A) is shown in FIG.
Not only the convex arc surface as shown in the basic embodiment of the above, but also a flat surface or an inclined surface parallel to the surface of the tile (T), or a sharp surface such as a V-shape or a saw-tooth shape can be appropriately selected. it can.

FIGS. 8 to 10 show a state of repairing an outer wall of a building by the method of the present invention. In repairing a floating portion of a tile (T) attached as an outer wall material, first, the tile is repaired. The floating portion of (T) is determined by percussion or the like, and an appropriate concrete cutter (K) such as an electric circular saw or a diamond cutter is used for the joint (B) of the floating tile (T). A slit (1) having a constant opening length (L1) adjacent to such a floating tile (T)
6) is cut as the depth (D1) reaching the inside of the base mortar (M). The opening width (W2) of the slit (16) is slightly larger than the width (W) of the anchor plate (A), for example, about 2.0 mm. The symbol (t) in the figure is the floating margin of the floating tile (T),
(C) indicates the concrete skeleton of the building.

Next, as shown in FIG. 7, an anchor plate (A) having a size corresponding to this is inserted into the slit (16), so that the ridge (11) of the anchor plate (A) is inserted. ) Bites on the floating tile (T) and its joint (B), while the concave streak (12) is also kept open.

Then, using a spray gun or the like, an adhesive (13) such as the above-mentioned epoxy resin or polymer cement slurry is removed from the open groove (12).
Inject. Then, as suggested from FIGS. 8 to 10, the adhesive (13) is applied between the adjacent plates of the anchor plate (A) and the floating tile (T) as well as the anchor plate through the concave streak (12). (A) and the joints (B) are not only between adjacent ones, but also penetrate and fill the floating margin (t) of the floating tile (T) and the inside of the base mortar (M). Since the floating tile (T) is stably fixed to the base mortar (M) with high strength with the sole (A) as a sole, the risk of peeling due to the floating can be reliably prevented.

Finally, the anchor plate (A) exposed from the slit (16) of the joint (B) is concealed in an elegant appearance by a correction joint (B1) having a color tone that matches the old joint (B). Just do it. Therefore, there is no possibility that the tiles (T) will be cracked or chipped, and the tiles (T) can be repaired extremely efficiently by correcting only the missing portions of the joints (B). The anchor plate (A) shown in the various modified embodiments of FIGS. 2 to 4 has the same repair method as that of the tile (T) by using the anchor plate (A).

In the repair method of the tile (T) described as the basic embodiment, the anchor plate (A) is inserted into the slit (16), and then the slit (1) is inserted.
From 6), the anchor plate (A) is bonded between the floating tiles (T) and between the adjacent anchor plates (A) and the joints (B) until the anchor plate (A) reaches the inside of the base mortar (M). Although the agent (13) is injected, the adhesive (13) may be applied in advance to the entire surface of the anchor plate (A) and inserted into the slit (16).

According to this, although the adhesive (13) does not spill over into the floating allowance (t) of the floating tile (T), the anchor plate (A) is held by the adhesive (13). Since the floating tile (T) can be fixedly integrated with the joint (B) and the base mortar (M), the effect of preventing the floating tile (T) from falling off can be achieved.

In the case of the repair state shown in FIGS.
In order to fix each of the floating tiles (T) one by one so as not to be peeled off, the inside of the slit (16) cut into the joint (B) adjacent to one side of the floating tile (T) is shorter than the one side. Although the anchor plate (A) having a length (L) is inserted, the cut opening length (L1) of the slit (16) with respect to the joint (B) is set to a plurality of floating tiles (T) as shown in FIG. Alternatively, a plurality of floating tiles (T) and healthy tiles (T1) as shown in FIGS. By inserting the plate (A) into the slit (16) and using it,
This can be connected and fixed all at once as a sole foot common to a plurality of tiles (T) (T1).

According to this, it is effective when the area of the floating portion is very large. According to the repair method shown in FIGS.
Since the floating tile (T) is also fixedly integrated with the sound tile (T1) via the anchor plate (A), it can be said that it is useful for enhancing the above-mentioned peeling prevention effect. FIG. 11 illustrates a repair state applied to a tile (T) allocated as a horse joint, and FIG. 12 illustrates a repair state applied to a through joint (potato joint).

Further, the anchor plate (A) is bent into an angle shape in plan view, and this is defined as a positional relationship adjacent to the corner of the floating tile (T) as shown in FIG. In the same manner as described above, a plurality of floating tiles (T) or a plurality of floating tiles (T) and sound tiles (T1) are inserted into the angle-type slits (16) having corresponding openings, as shown in FIG. May be inserted into a slit (16) opened in a long angle shape as the length (L1) adjacent to and straddling.

In any of the above anchor plates (A), a pressing flange (17) for preventing the tile from floating is formed on the head thereof so as to protrude therefrom. By locking it, the spalling prevention effect can be enhanced.

[0026]

As described above, in the tile repairing method according to the present invention, the slit (16) having a fixed opening length (L1) adjacent to the floating tile (T) is provided at the joint (B) with the base mortar. A cut is made as a constant depth (D1) reaching the inside of (M), an anchor plate (A) serving as a sole of the floating tile (T) is inserted into the slit (16), and the anchor plate (A) is inserted. Is fixed to the floating tile (T) alone or to both the floating tile (T) and the joint (B) by the adhesive (13), so that the problems of the prior art described at the beginning are solved. There is an effect that can be completely improved.

That is, according to the method of the present invention, the slit (16) having a fixed opening length (L1) adjacent to the floating tile (T) is cut into the joint (B), and the cut slit (16) is cut. Since the anchor plate (A) is to be inserted, the repair work of the mosaic tile and other small tiles can be performed without any trouble.

At this time, since the tile (T) is not cut into itself or the joint (B) is not cut off, there is no possibility that the tile (T) is chipped or cracked. By simply correcting it later, the repair work can be performed extremely efficiently and easily, and in spite of that, the tiled state with an elegant cosmetic effect can be maintained.

The slit (16) has a depth (D1) reaching the inside of the base mortar (M), and the anchor plate (A) inserted therein is floated on the tile (T).
The anchor plate (A) is fixed to and integrated with only the floating tile (T) and the joint (B) via the adhesive (13). ), The floating tile (T) is stably fixed and maintained at a high strength, and the effect of preventing the tile from falling off can be completely achieved.

In particular, if the method of claim 2 is adopted,
When the floating portion of the tile (T) extends over a wide area, the efficiency of the repair work can be further improved, and the floating tile (T) can also be used as a healthy tile (T1) via the anchor plate (A). Since it is fixed and integrated, it is useful for enhancing the above-described effect of preventing the exfoliation.

If the method of claim 4 and particularly the method of claim 3 is adopted, since the adhesive (13) also penetrates and penetrates into the floating margin (t) of the floating tile (T), it has a high fixing strength. It has excellent durability to prevent spalling.

On the other hand, if the structure according to claim 5 is adopted as the anchor plate (A) for carrying out the above method, a plurality of ridges (11) arranged in the depth direction of the surface thereof. By means of the ridges (12), the adhesive strength of the adhesive (13) to the surface of the anchor plate (A) and the fixing strength of the floating tile (T) and its joint (B) can be increased. There is also an advantage that the mass production effect of the anchor plate (A) can be expected.

Further, if the configuration of claim 6 is adopted,
By locking the holding flange (17) of the anchor plate (A) to the floating tile (T), the effect of preventing the spalling can be more and more completely achieved.
