[0011]

BEST MODE FOR CARRYING OUT THE INVENTION A method for removing a plate-like building material according to the present invention will be described below in detail with reference to the drawings.

1 (A) to 1 (G) are cross-sectional explanatory views showing an example of a method of removing a plate-like building material according to the present invention in the order of steps, FIG. 2 is a plan view of FIG. 1 (C), and FIG. It is the top view which took out only the adhesive part in C).

Examples of the plate-like building material to be removed by the method of the present invention include large tiles, humidity control tiles, glass building materials, and plate-like stone materials. Among them, the humidity control tiles are mainly composed of calcium carbonate or amorphous silica. It has lower strength than ordinary tiles in terms of manufacturing, and is attached to the construction surface except for the part where the adhesive is not applied. In such a case, damage such as breakage or chipping is likely to occur.

Therefore, as a plate-like building material to be removed from the construction surface targeted by the present invention, a humidity control tile is the most representative, and the present invention will be described below with a plate-like building material to be removed as a humidity control tile.

In the present invention, the humidity control tile 1 to be removed from the construction surface 8 is attached to the construction surface 8 via an adhesive 2 as shown in FIG. The beads are applied in a substantially linear shape as described later.

When removing the humidity control tile 1 from the construction surface 8, first, as shown in FIG. 1B, a cutting circumferential groove 3 is provided along the outer periphery of the humidity control tile 1, and furthermore, as shown in FIG.
As shown in (C), a plurality of lattice portions 5 are formed on the surface of the humidity control tile 1 to be removed by providing cutting cross grooves 4 orthogonal to each other in a portion surrounded by the cutting circumferential grooves 3.

When the humidity control tile 1 to be removed is small, it can be removed only by providing the cutting circumferential groove 3, but the humidity control tile 1 is usually 30 to 50 cm square and has a construction surface 8. , The removal thereof is further facilitated by providing the cutting cross groove 4.

The cutting circumferential groove 3 along the outer periphery of the humidity control tile 1
Not only is the removal of the humidity control tile 1 effective, but also the effect of preventing damage to the humidity control tile located around the humidity control tile 1 which does not need to be removed is achieved. That is, since the section in contact with another humidity control tile along the outer periphery of the humidity control tile 1 to be removed is extremely small, it is possible to easily remove the humidity control tile 1 without applying an excessive force to this portion. In addition, it eliminates the problem of accidentally damaging a humidity control tile that does not need to be removed.

In the case where the crossing grooves 4 orthogonal to each other are provided in the portion surrounded by the cutting circumferential grooves 3, the starting and ending points of the processing can be clearly and visually recognized in response to the provision of the cutting circumferential grooves 3. Since it can be confirmed, the cutting cross groove 4 does not accidentally reach the surrounding humidity control tile that does not need to be removed.

The formation of the cutting circumferential groove 3 and the cutting cross groove 4 is as follows.
This is performed by cutting the surface of the humidity control tile 1 by a rotary motion of a cutting blade using a trimmer, a luter, an electric saw, or the like. In this case, since there is no hitting motion, vibration and noise can be reduced, and fragments of the humidity control tile 1 do not scatter. In addition, the point which does not damage the construction surface 8 and the generation and scattering of dust is relatively small,
The use of a trimmer is most preferred.

As described above, the cutting circumferential groove 3 and the cutting cross groove 4
FIG. 2 shows a state in which a plurality of lattice portions 5 are formed by providing the above.

When the plate-like building material is the humidity control tile 1, the construction surface 8 is usually left with a portion to which no adhesive is applied.
Is attached to That is, as shown in FIG. 3, the adhesive 2 is bead-applied in a substantially linear shape, and the humidity control tile 1 is adhered to the construction surface 8 via the adhesive 2.

Accordingly, for example, the application of the adhesive 2 is confirmed by obtaining the application manual of the humidity control tile 1 and the like, and at least a part of the cutting circumferential groove 3 and the cutting cross groove 4 is attached. It is desirable to provide along the agent 2, and by doing so, it becomes possible to further facilitate the work of peeling and removing the lattice portion 5 and the adhesive residue described later.

The depths of the cutting peripheral groove 3 and the cutting cross groove 4 are substantially equal to the thickness of the humidity control tile 1 to be removed, and the width is preferably set to about 3 to 6 mm.

After forming the lattice portion 5 in this manner,
As shown in FIGS. 1 (D) and 1 (E), a rod-like body, for example, a bur 6 is inserted into an appropriate position of the cutting circumferential groove 3 and / or the cutting cross groove 4, and this is applied in the direction of the arrow by leverage. By applying force, each lattice portion 5 is peeled and removed for each section.
By doing so, each grid portion 5 can be easily removed with little effort without scattering of debris, and the cutting circumferential groove 3 and the cutting cross groove 4 are provided along the adhesive 2. Results in a reduced adhesive area
It can be more easily removed.

In this case, at the end, the outer peripheral portion of the humidity control tile 1 remains integrally. However, since the outer peripheral portion has a small width, it can be easily removed without damaging the surrounding tiles with a bur or a chisel. It is.

When a bar is used as the rod 6, it can be used in the grid section 5 in a small section partitioned by the cutting circumferential groove 3 and the cutting cross groove 4, and after the grid section 5 is peeled off. When the construction surface 8 is exposed, the construction surface 8 may be used by being inserted between the humidity control tile 1 or the adhesive 2 and the construction surface 8.

After the lattice portions 5 are peeled and removed in this manner, as shown in FIG.
1 'and the adhesive residue 2' are peeled and removed from the construction surface 8 using a chisel 7, a scraper, a cutter knife, or the like to obtain a smooth construction surface 8 as shown in FIG. 1 (G). Can be.

Even when the construction surface 8 is a fragile gypsum board, the damage can be minimized. On the contrary, the concrete is made of strong concrete, and the humidity control tile 1 is firmly attached. Even if there is, the grid portion 5 can be easily separated and removed by increasing the number of cutting cross grooves 4 and further reducing the size of the grid portion 5.

The moisture-control tile 1 peeled and removed in this manner may be put as it is, or may be pulverized by appropriate pulverization to adjust the particle size, and then put directly under the floor or put in an air-permeable bag. In this case, the moisture-control tile can be used as a humidity control material for underfloor or press-fitting, and in this case, the removed humidity control tile can be effectively reused.

In the above description, an example in which a humidity control tile is used as the plate-like building material has been described. It is needless to say that the present invention can also be applied to the detachment of the vehicle.

After the damaged or contaminated plate-like building material is removed as described above, a new plate-like building material is further pasted through an adhesive to easily complete the work of replacing the plate-like building material. can do.

As described above, according to the method for removing a plate-like building material of the present invention, noise or debris scattered by crushing does not endanger workers and surrounding articles, and can be used for other plate-like materials. A damaged or contaminated plate-like building material can be easily and safely peeled off without damaging the building material.

When the plate-like building material is a humidity-controlling tile, the removed humidity-controlling tile is used as a humidity-controlling material, in particular, a floor-floor or push-in humidity-controlling material. It can be reused.

m, and three crossing grooves orthogonal to each other are provided at regular intervals in a portion surrounded by the cutting circumferential grooves, and a total of 16 lattice portions are provided on the surface of the plate-like building material to be removed. Was formed. In this case, after obtaining the execution manual and confirming the application state of the adhesive, at least a part of the cutting circumferential groove 3 and the cutting cross groove 4 is aligned with the applied adhesive 2. Provided.

Next, a bar was inserted into an appropriate position of the cutting circumferential groove and / or the cutting cross groove, and each lattice portion was peeled off by section by applying force by leverage. With a small amount of labor, it could be easily carried out without scattering of fragments and generation of noise.

Thereafter, a flat construction surface can be formed by peeling and removing the plate-like building material residue and the adhesive residue remaining on the construction surface with a chisel. There was no damage to the humidity control tile that did not need to be removed.

Then, by attaching a new humidity control tile to the flat construction surface via an adhesive, the work of replacing the humidity control tile could be completed efficiently.

The removed pieces of the humidity control tile were put under the floor of a house and reused as a humidity control material without being discarded.
