Description

  The present invention relates to a method for repairing a tiled outer wall for repairing a tile that has been peeled off or damaged by cracking or the like on a tile wall applied to an outer wall or the like of a building.

  Conventionally, many buildings have tiles attached to the outer wall. However, such tile wall surfaces need to be repaired as some of the tiles come off or crack as they age. In addition, when building scaffolding around the building for repairing the building, not just repairing the outer wall, anchor bolts must be driven into the building outer wall to prevent the scaffolding from falling down, but at that time it is attached to the outer wall You may break a tile.

  In such a case, in order to keep the appearance of the building in good condition, it is necessary to repair tiles that have been peeled off or to replace damaged tiles. There was a method in which spare tiles were stored at the time of new construction and repaired using the stored tiles when the tiles were damaged. If there are no storage tiles, they can be repaired using tiles with similar colors and shapes, or special orders from tile manufacturers can be made and repaired using these tiles.

Moreover, as shown in Patent Document 1, tiles have been entirely peeled off and replaced with new tiles.
JP 60-59262 A

  However, among the above-mentioned conventional repair methods, the method of storing spare tiles at the time of new construction requires storage management over a long period of time, and in some cases, such as when the tiles used are quite old, Since the surrounding tiles deteriorate with age, the tiles that have been replaced become conspicuous and the appearance is impaired. In addition, the method of using tiles with similar colors and shapes also has the problem that the tiles that have been replaced become more noticeable and the appearance is impaired. In addition, the method of making the same tile by making a special order to the tile manufacturer is that the special order for a small amount of tiles increases the cost significantly, and if the tile used is quite old, the diameter There was a problem that harmonization with surrounding tiles that deteriorated in years could occur. Furthermore, peeling the tiles completely and replacing them with new tiles eliminates the appearance problem, but there is a problem that the construction takes a lot of cost and time.

  The present invention has been made in view of such problems, and it is an object of the present invention to repair a tiled outer wall in which some tiles have been peeled off or damaged without lowering the appearance and at a low cost. It is what.

  In order to solve the above-mentioned problem, the repair method of the tiled outer wall according to claim 1 has a diameter larger than the short side width of the tile around the tile joint in a portion that is not directly visible from the outside of the tiled outer wall, A step of providing an opening deeper than the thickness of the tile, a step of removing the adhesive filling the tile joints to form a groove, a rotation axis smaller than the width of the groove, and a diameter smaller than the short side width of the tile. Inserting a large rotary cutting blade from the opening and moving the rotation axis along the groove removes the adhesive on the lower side of the tile and peels the tile from the wall body, and the peeled tile And a step of repairing a part where the tile is peeled off or damaged, which is directly visible from the outside of the tiled outer wall.

  Further, in the repair method of the tiled outer wall according to claim 2, in the portion that is not directly visible from the outside of the tiled outer wall, the diameter is larger than the short side width of the tile and deeper than the thickness of the tile, centering on the tile joint. A step of providing an opening, and a rotary cutting blade mounted with a small-diameter cutting blade and a large-diameter cutting blade on the rotating shaft so that the latter is positioned on the tip side, the large-diameter cutting blade from the opening completely Insert until it enters, and move the rotation axis along the tile joint to remove the tile joint and the adhesive on the lower side of the tile to peel the tile from the wall body, and use the peeled tile And a step of repairing a part where the tile is peeled off or damaged, which is directly visible from the outside of the tiled outer wall.

  The method for repairing a tiled outer wall of the present invention has the following effects.

  That is, in the repair method of the tiled outer wall according to claim 1, the portion that is not directly visible from the outside of the tiled outer wall has a diameter larger than the short side width of the tile and deeper than the thickness of the tile, centering on the tile joint. An opening is provided, the adhesive filled in the tile joint is removed to form a groove, a rotary cutting blade having a diameter larger than the short side width of the tile is inserted from the opening, and the rotation axis is along the groove Remove the adhesive on the bottom side of the tile by moving it, peel the tile off the wall body, and use the peeled tile to remove the tile from the part that is directly visible from the outside or damaged part The repair of. As a result, it is possible to repair a tiled outer wall in which some tiles have been peeled off or damaged using tiles in the same state as the surrounding tiles, and can be constructed at a low cost without impairing the appearance.

  Further, in the repair method of the tiled outer wall according to claim 2, the rotary cutting blade having a small-diameter cutting blade and a large-diameter cutting blade attached to the rotary shaft so that the latter is located on the tip side, Insert the large-diameter cutting blade through the opening until it completely enters, and move the rotation axis along the tile joint to remove the tile joint and the adhesive under the tile and pull the tile from the wall body. Since it peeled off, the process which removes the adhesive agent with which the tile joint is filled, and forms a groove | channel in advance becomes unnecessary, and working efficiency improves.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The method of repairing a tiled outer wall according to the present invention is such that when a part of a tile on a building outer wall is peeled off or damaged, the tile that is not directly visible from the outside of the building is peeled off and directly visible from the outside of the building. Attached to the fallen part or replaced with a damaged tile. At this time, the tiles that are not directly visible from the outside of the building are removed as follows.
In other words, as shown in Fig. 1, some tiles on the wall that cannot be directly seen from the outside, such as the inner lower part of the roof peripheral wall of the building, are cut out using an electric cutter with a diamond blade, or using chisel etc. Then, an opening 3 having a diameter larger than the short side width of the tile 1 and deeper than the thickness of the tile 1 is provided centering on the tile joint 2 by peeling off a necessary number of tiles. Then, an adhesive such as mortar filling the tile joint 2 is removed using an electric cutter with a diamond blade to form the groove 4. At that time, the groove 4 is provided with a starting end portion continuously from the opening 3. Note that either the opening 3 or the groove 4 may be formed first.

  When the opening 3 and the groove 4 are thus formed, a blade of an electric cutter having a rotating cutting blade whose diameter is smaller than that of the opening 3 and larger than the short side width of the tile 1 is inserted from the opening 3. Then, as shown in a cross-sectional view in FIG. 2 and a rotary cutting blade in FIG. 3, an electric cutter 8 in which a rotary cutting blade provided with a diamond blade 11 around the disk portion 10 is attached to the tip of the rotary shaft 9 is used. While rotating the rotary cutting blade, the rotary shaft 9 is moved along the groove 4 to remove the mortar 6 on the lower side of the tile 1 and peel the tile 1 from the wall body 7.

  At that time, since the diameter of the diamond blade 11 is larger than the width of the short side of the tile 1, the electric cutter 8 is moved along the long side of the tile, and if it is performed on both opposing sides, the lower side of the tile 1 is formed. Some mortar 6 can be completely removed. In the illustration, the diameter of the rotary cutting blade is set to be slightly more than half the width of the short side of the tile, but the diameter is increased to more than twice the width of the tile, and the operation can be performed in one operation. The entire mortar under the tile on both sides of the tile joint may be removed. By doing so, the work efficiency is further improved. In addition, new tiles with similar colors and shapes will be placed on the traces of the tiles that have been peeled off in this way, but this part is not visible directly from the outside of the building. There is no problem. In this way, a repair tile can be secured without damaging the tile.

  The tiles peeled off as described above are used for repairing the part of the tiled outer wall that is directly visible from the outside of the building, where the tiles have been peeled off or damaged. In addition, the mortar which was not able to be removed by the electric cutter 8 is attached to the peeled tile, and it is necessary to remove the mortar in order to reuse the tile. At that time, the tile to which the mortar is attached. It can be easily removed by immersing the lower surface of the material in an acid such as sulfuric acid or hydrochloric acid to degrade the mortar and then removing it. In that case, the tiles are made of porcelain and are not very sensitive to acid.

  In the above embodiment, the grooves 4 are formed in advance. However, the mortar 6 on the lower side of the tile 1 can be removed while the grooves 4 are formed by the electric cutter 8. That is, as shown in a cross-sectional view in FIG. 4 and a rotary cutting blade in FIG. 5, a diamond blade 12 having a diameter slightly smaller than the width of the tile joint 2 is provided at the center of the disk portion 10 of the rotary cutting blade. 8 is attached to the rotary shaft 9.

  The rotary cutting blade is inserted into the opening 3, and the diamond blade 12 is applied to the tile joint 2 where the mortar remains clogged and pressed in the direction of the tile joint 2. As a result, while the mortar of the tile joint 2 is removed by the diamond blade 12, the mortar 6 on the lower side of the tile 1 can be removed by the diamond blade 11, and the tile 1 can be peeled off.

It is a figure explaining the repair method of the tiled outer wall of 1st Example. It is sectional drawing which shows the state which has peeled off the tile of 1st Example. It is a figure which shows the cutting blade of 1st Example. It is sectional drawing which shows the state which has peeled off the tile of 2nd Example.
