Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing large tiles on a wall surface or the like.

There are two methods for installing tiles: one method is to attach cement mortar to the back of the tile and then press it to the base of the area to be installed, and the other is to attach cement mortar to the base of the area to be installed and then press the tile to that area. There is a pressure-bonding method in which the tiles are laid down, but when constructing large tiles like the one for which the present invention is being applied, the pile-up method uses an even layer of cement mortar, which often falls off after being pressed down to the base. The disadvantages of the pressure bonding method include the difficulty in applying cement mortar in large quantities, but since the tiles are laid by rolling and pressing, it is difficult to ensure that the adjacent tiles are flush, and the cement mortar is applied in large areas. However, the bond between the cement mortar and the tile becomes poorer as the time progresses, so the cement mortar has to be attached to each small section, which is not preferable. There are also methods that use organic adhesives or resin mortar instead of cement mortar, but they are more expensive than cement mortar, and if the structure is deformed, the tiles may crack or break or fall off. There is a danger that In addition, in the case of large tiles with a thickness of 15 mm or more, a hole is made on the back of the tile, a copper wire is passed through the hole, and the tile is tied to the frame protruding from the structure's frame, and mortar is placed between the frame and the tile. Alternatively, there is a method of pouring concrete, but this method cannot be used with tiles less than 15 mm thick as the hole will collapse.

The present invention solves the above-mentioned drawbacks and has a thickness of 5.
This provides a method for easily and uniformly installing tiles of ~10 mm on walls, etc.

The present invention will be explained in detail below with reference to the drawings.

First, as shown in FIG. 1, a mask plate 3 is prepared by providing a large number of through holes 2 of arbitrary shapes in a plate-like body 1 such as a wooden board such as plywood or a synthetic resin board. The shapes of the through holes are squares of the same size arranged regularly as shown in Figure 1 a, circular holes as shown in b, and hexagonal holes arranged in a honeycomb shape as shown in c. , or a large number of squares of different sizes, or circles of different sizes,
Alternatively, a triangular shape, a mixture thereof, or a completely irregular shape as shown in d can be arbitrarily selected.

Next, as shown in FIG. 2, the mask plate 3 is placed on the back side of the tile 4, and a cement mortar 5 mixed with an admixture such as a rubber emulsion is supplied from above, and the cement is Mortar is packed into the through hole 2.

Next, when the mask plate 3 is removed from the tile, cement mortar 5 is adhered to the back side of the tile in the form of a large number of islands having the same shape as the through holes in the mask plate, as shown in FIG.

Next, as shown in FIG. 5, tiles 4 are pressed against a predetermined wall surface 6 to be constructed with their cement-adhered surfaces facing the wall surface.

When removing the mask plate from the tile, cement mortar residue will adhere to the area around the hole, so the mask plate will need to be cleaned after each use, but if you apply wax, etc. to the perforated area, Cleaning becomes easier.

The total area of the through holes relative to the total area of the back surface of the tile, that is, the porosity is preferably 60% or more; if it is less than 60%, sufficient adhesive strength between the tile and the wall surface cannot be obtained. Further, depending on the size and weight of the tile, the aperture ratio of the mask plate is arbitrarily determined within a range of 60% or more.

Tiles suitable for installation by the method of the present invention have a thickness of 5 to 10 mm, a weight of 1.5 to 6.0 kg, and a size of 0.09 to 0.4 ^m2 , and if the thickness is less than 5 mm, during production, It cannot be used because it is easily damaged during transportation or construction. Moreover, if it is 10 mm or more, sufficient adhesive strength cannot be obtained and construction cannot be performed. In addition, tiles weighing less than 1.5 kg or measuring less than 0.09 m ² can be installed using conventional methods, whereas tiles over 6.0 kg or 0.4 m ² have poor workability and do not have sufficient adhesive strength. I can't.

Since the tiles constructed by the method of the present invention are larger than conventional tiles, the base surface 7 when pasting them is
If there is any unevenness in the tile or the tile itself, there will be areas where it will not adhere, so if you press the tile against the wall and then apply vibrations to the tile in a direction perpendicular to the wall, the cement mortar will move and the recesses in the wall will be moved. This will give sufficient adhesive strength. Furthermore, even if the tile itself has unevenness, the cement mortar fills in the unevenness and provides a uniform surface that is almost the same as the surface of the mask plate, so there is no problem of poor adhesion caused by the unevenness of the tile itself. .

In addition, in order to withstand the weight of the tiles and obtain sufficient adhesive strength, it is necessary to use cement mortar with a high initial adhesive strength, and instead of mixing with water, an admixture such as a rubber emulsion is used.

As described above, according to the method of the present invention, the following effects can be obtained.

Even if there are some irregularities on the wall surface or the back of the tile, it can be applied with sufficient adhesion.

Since there is a joint-like non-adhesive surface on the surface of the tile to which cement mortar is attached, it is possible to absorb fluctuations due to distortion or shrinkage of the wall material or structural frame and prevent damage to the tile.

Since the cement mortar is applied through the mask plate, the amount of cement mortar applied can always be kept constant.

Example: 5.5mm thick lauan plywood, size 11cm x 11
A mask plate is made by providing square holes of 1 cm in a grid pattern at 1 cm intervals, 7 mm thick, 3 kg in weight, and 0.25 m ² in size.
(50 cm x 50 cm) was placed on the back side of the tile, and cement mortar mixed with a rubber-based emulsion admixture was filled into the holes using a rubber trowel.

Next, the mask plate was removed from the tile, the back surface of the tile was pressed against the surface-treated wall surface, and the tile was attached to the wall surface by applying vibration in a direction perpendicular to the wall surface from the surface of the tile.
