Description

  The present invention relates to a method for repairing cracks on a tiled surface for interior and exterior use, which eliminates the possibility of repeated cracking after repairing cracks on the tiled surface.

  In general, buildings with tiled finishes as exterior finishing materials are often seen in recent years because they are full of luxury and have excellent durability. However, due to various effects such as ultraviolet rays, rainwater, acid gas, earthquakes, etc. over a long period of time, dirt on the tile surface, cracking, floating, peeling, effluent effusion of joints, progress of neutralization of concrete, and water leakage Various deterioration phenomena have been observed, and appropriate repairing of the tiled surface has become important. For this reason, at present, there are many cases where a water-repellent treatment or a thin-film paint with a degree of dirt prevention is applied to the tiled surface, but high waterproof performance cannot be expected. The reason for this is considered to be that there was no waterproof material having a transparent coating film on the tile-attached surface, a thick film, and an excellent crack following ability. In addition, in apartments with tiled finishes, after 10 years of construction, cracks (5) occur on the side of the cabinet due to the effects of earthquakes and shrinkage of the concrete, and cracks to the tile ceramic pieces ( 5) occurs [see FIG. 1 (a)], and many rainwater infiltrates into the concrete and flows out of the white efflorescence and becomes dirty.

  In this case, the method of repairing cracks on the tiled surface of the outer wall is generally to peel off and remove the cracked tile (4) and the minimum tile porcelain necessary for the repair work, and then apply epoxy to the crack (5) on the housing side. A process of filling the cracks (5) by injecting an injection material such as resin and infiltrating deep into the concrete is performed, or deep U-cut along the cracks (5) and filling the U-cut groove with a sealing material The process to perform was performed [refer FIG.1 (b)]. Then, after the injection material or the sealing material is solidified, a tile attaching process is performed in which a new tile ceramic piece is attached to the peeled position, and a joint material is buried between the tile ceramic pieces to repair the crack of the tile attachment surface. It was finished.

  However, even if the process of filling the crack (5) or the process of filling the U-cut groove with a sealing material is performed and a new tile ceramic piece is attached and repaired, the frame side will move once and the cracked part will be reinforced. However, since it is easy to move due to an earthquake or the like, the tile ceramic piece at the repaired site is very easily cracked (5), and it was necessary to repeat the replacement of the tile ceramic piece. For this reason, there are cases where a method using an adhesive having elasticity is applied, but there is no effective countermeasure against cracks at present.

In addition, without removing the tile ceramic pieces, a method of U-cutting deeply along the crack (5), filling the U-cut groove with a flexible putty material and assimilating the tile ceramic pieces to the surroundings in a pseudo manner, It has been proposed by the present inventor as Japanese Patent Application No. 2002-162524 “A method for repairing cracking of a tiled surface for interior and exterior use”.
Japanese Patent Application No. 2002-162524

  It is an object of the present invention to provide a method for repairing a crack on a tiled surface for interior and exterior use that eliminates the possibility of repeated cracking after repairing a crack on the tiled surface.

  Another object of the present invention is for interior and exterior use where the tiles are finished with a natural feeling that is almost indistinguishable from the previous ones even when the cracks in the interior or exterior of the tiles differing in color tone or color are repaired. The present invention relates to a crack repair method for tiled surfaces.

  The present invention has been made in view of the above-described situation. That is, after a cracked tile is peeled and removed, a flexible tile is pasted to form a crack repairing method for a tile-attached surface. As the tile at this time, it is preferable to use a synthetic resin in which a mesh-like reinforcing material is embedded, and the tile surface is assimilated to the surroundings by using different colors and colors. Is good. In addition, after repairing the cracks on the housing side, it is preferable to stick a tile to the peeled position and use a soft joint material between the tiles. In the present invention, “one having a different color tone or color” is applied to make the color tone and color the same as the cracked tile ceramic pieces and to assimilate the remaining tile ceramic pieces. Refers to surface treatment.

  The flexible tile (1) as in claim 1 is attached to the position where the cracked tile (4) is peeled off and removed, so that the crack repaired part moves due to an earthquake or the like and the gap moves. However, the flexible tile (1) only needs to move slightly, so that the surface of the tile (1) is not cracked (5). Therefore, there is no risk of rainwater penetrating from the surface to the housing side, so that tile ceramic pieces as in the past are not repeatedly re-applied, and maintenance is hardly applied.

  By using the tile (1) embedded with the mesh-like reinforcing material (2) as in claim 2, the dimensional stability of the tile (1) with respect to the outside temperature as well as the reinforcing effect of the tile (1) is Since the expansion and contraction in the vertical and horizontal directions is suppressed by the reinforcing material (2), the dimensional difference between summer and winter is small, and the burden on the joint material (3) is reduced. The material (3) becomes difficult to break.

  The surface of the tile (1) as shown in claim 3 is colored and finished so that there is no sense of incongruity with the surrounding existing tile ceramic pieces by using one having a different color tone or color for each sheet. If applied, the appearance of walls and floors will look as good as existing tile ceramic pieces.

  As shown in claim 4, after repairing cracks on the housing side, the tile (1) is attached to the peeled position, and the joint material (3) is embedded between the tiles (1), so that the work can be performed in the same manner as before and the surroundings It can be assimilated with the tile ceramic pieces.

  When a soft material is used for the joint material (3) as in the fifth aspect, the vibration on the frame side can be absorbed by the tile (1) and the joint material (3).

  FIG. 1 is a diagram showing an embodiment of the present invention, and this figure number will be described. (1) is a tile made of synthetic resin such as urethane resin, elastic epoxy resin, and soft polyester resin for repair and flexibility. The tile (1) has the same shape and the same as the removed tile ceramic piece. It is of a size. Further, on the surface of the tile (1), as shown in FIG. 2, a primer coating, a coating applied with a paint prepared for assimilation with surrounding tile ceramic pieces, and a coating applied to the surface of the coating A multilayer film composed of a transparent protective film is formed. The multilayer film may be the same as the multilayer film formed in Japanese Patent Application No. 2003-126861 proposed by the present inventor. In addition, as the flexibility of the tile (1), one having elasticity is particularly preferable.

  (2) is a mesh-like reinforcing material embedded in the center position of the tile (1). As the reinforcing material (2), a glass mesh or a resin mesh may be used. In particular, when a glass mesh is embedded, the dimensional stability with respect to the outside temperature is good as well as the reinforcing effect of the tile (1). Moreover, if a cross mesh is used as the resin mesh, the vertical and horizontal dimensions of the tile (1) with respect to the outside air temperature become stable. In addition, the embedding position of the reinforcing material (2) is not limited to the center of the tile (1). (3) is a joint material embedded between the tiles (1) attached to the peeling position, and it is preferable to use a soft material as the joint material (3). (4) is a tile ceramic piece such as an outer wall and a cracked tile. The “cracked tile” referred to in the present invention refers to a tile attached to a sticking surface as an exterior or interior finish material, and includes bricks, stone blocks or plates in addition to ceramic tiles. (5) is a crack generated on the housing side, and the crack (5) is also generated on the tile ceramic piece.

  Next, the repair method of the present invention will be described with reference to FIG. First, in the case where cracks (5) are generated as shown in FIG. 1 (a) in tiled places such as the outer wall, inner wall, or floor surface, the cracked tiles (4) generated on the outer wall or inner wall, etc. Then, as shown in FIG. 1 (b), the minimum tile ceramic pieces necessary for the repair work are peeled off and removed, and deep U-cut along the crack (5), and the U-cut groove is filled with the sealing material. [Refer FIG.1 (b)]. At this time, when repairing the crack (5) on the housing side, the injection material may be directly injected from the crack (5) without U-cutting, and the injection material may penetrate deep into the concrete on the housing side.

  After the sealing material is solidified, the tile attachment surface is flattened and the crack repair on the housing side is completed. And the tile (1) which has flexibility is affixed on the peeled position [refer FIG.1 (c)]. Thereafter, the joint material (3) is embedded between the tiles (1) as shown by the hatched portion in FIG. 1 (d) and the surface is cleaned to complete the restoration work. In addition, in order to assimilate the tile (1) with the existing tile ceramic piece, in the Japanese Patent Application No. 2003-126861 “Tile for interior / exterior used for restoration” proposed by the present inventor, it is simulated assimilated with the surroundings. As in the method, it is preferable to prepare a tile whose surface is previously colored and use this tile (1).

  When repairing a crack on a tile-attached surface such as an outer wall, an inner wall, or a floor in this manner, the tile (1) prevents new cracks (5) from occurring on the surface and prevents water from entering. Therefore, the waterproof effect of the repaired portion is exhibited over a long period of time. Further, the tile (1) is lighter than half of the existing tile ceramic piece, and is less likely to fall off. Even if this tile (1) is dropped, there is no risk of cracking, so there is no risk of injury to surrounding people, and the safety is extremely high.

It is explanatory drawing which shows embodiment of this invention. It is explanatory drawing which shows the cross section of the tile used by this embodiment.
