Description

  The present invention relates to a method for attaching a tile to a building substrate via an adhesive layer.

2. Description of the Related Art Conventionally, as a method for aligning the positions of a plurality of tiles when attaching and fixing tiles on a wall surface, a method has been proposed in which yarns are preliminarily placed on a surface to which tiles are attached and positioning is performed using these yarns as a guide.
According to such a method, the thread fixing pins are locked to both ends of the wall surface on which the tile is to be attached, and the thread is stretched between the thread fixing pins. Therefore, even if an adhesive such as mortar is applied to the wall surface using a trowel, the tiles can be positioned without being covered with adhesive like the ruled lines on the wall surface. It is possible. (For example, see Patent Documents 1 and 2.)

In addition, as another method for aligning the position of multiple tiles when attaching tiles to a wall surface, a jointing tape with scales at regular intervals on the surface of the double-sided adhesive tape is attached to the wall surface, and the tile is used as a reference. A method for performing positioning has been proposed. (For example, see Patent Document 2.)
Japanese Patent Laid-Open No. 62-133245 JP-A-1-165865

  In these conventional methods, a thread and a thread fixing pin or a joint tape are required. In the method of tensioning the yarn, not only does the yarn become an obstacle during the tile-laying operation, but there is also a problem that parallax occurs unless viewed from the front, and the yarn cannot be stretched at an accurate position. Furthermore, it is necessary to close the hole after the thread fixing pin is removed from the wall. Moreover, in the method using the joint-split tape, the positional accuracy is likely to deteriorate due to the adhesive strength and durability of the tape, the expansion / contraction of the tape, the unevenness of the building base material, and the like.

  The present invention has been made to solve the above problems, and an object of the present invention is to obtain a tiled construction method capable of accurately positioning a tile by a simple operation.

  In order to achieve the above object, the present invention includes a step of attaching a masking material along a reference line for positioning at the time of tile attachment provided on a building substrate, and an adhesive on the surface of the building substrate. The method includes a step of applying, a step of removing a masking material, and a step of attaching a tile. The boundary between the surface to which the adhesive is applied and the surface of the building substrate formed after removing the masking material is tiled. It is used as a guide for the pasting position.

  Masking materials are commonly used to cure areas where no adhesive is applied or where it is difficult for the adhesive to adhere. According to the present invention, the boundary formed by sticking the masking material along the reference line of the tile attachment position, applying the adhesive so as to partially overlap the masking material, and then removing the masking material. Since the line is used as a guide for the tile attachment position, it is possible to perform positioning more easily and accurately than the method using a thread or joint split tape. In addition, it is not necessary to use a yarn that hinders the work when tiles are attached, and it is not always necessary to look directly from the front so as not to generate parallax as in the case of using a water yarn, so that the work time can be shortened. Further, since no joint tape is used, the adhesive strength and durability are not impaired.

  Moreover, according to invention of Claim 2, when removing a masking material by making the thickness of the adhesive agent apply | coated to the said building base material surface into 2 mm or less, along the edge part of a masking material. The adhesive layer is cut, and an accurate boundary line can be obtained. That is, when the masking material is removed, the adhesive layer is pulled by the masking material when the masking material is removed, and the adhesive is peeled away from the boundary line or formed by removing the masking material. It is possible to prevent the boundary line from becoming unclear because the edge of the layer collapses or the masking material is broken.

  Furthermore, according to the invention described in claim 3, it is possible to easily set the thickness of the adhesive within the above range by applying the adhesive with a roller.

  According to the present invention, there is an effect of obtaining a tile construction method capable of accurately positioning a tile by a simple operation.

  Hereinafter, specific embodiments of the present invention will be described.

The building base material in the present invention refers to walls, floors, and building materials used for them. Moreover, any of existing, new installation, interior, and exterior may be sufficient, and it does not specifically limit. In existing building base materials, it is desirable to appropriately perform groundwork adjustment such as cleaning, filling of cracks and dents.
Hereinafter, the construction on the outer wall of a house will be described as an example.

Create a reference line on the tiled surface of the building substrate. The reference line is provided in order to determine the position of the tile to be attached to the building base material, and is created by ruled lines or inking on the wall surface. Generally, the reference line is set based on one end of the wall surface. In other words, the reference line drawn in the left-right direction of the wall surface is based on the lower end, upper end, opening, etc. of the wall, and the reference line drawn in the vertical direction of the wall surface is determined in accordance with a predetermined corner, opening, etc. Draw parallel lines at intervals. Alternatively, instead of drawing a line, only the positions at both ends of the reference line may be marked.
As another method, the vertical reference line may be created by lowering the weight at the tip of the yarn.

  The smaller the size of the reference line section, the easier it is to obtain the accuracy of the pasting position, and the larger the size, the higher the construction efficiency. Therefore, it is preferable that the size of the reference line is small until it gets used to, and increases as it gets used. Also, if the tile attachment position is likely to be difficult to understand because it is partially divided by an opening or the like, the section may be made smaller. Moreover, it is desirable to suppress to the area which can tile a tile within the pot life of the adhesive to be used. In addition, the size and aspect ratio of the reference line section are not particularly limited because they vary depending on the tile shape: size, single unit or unit, and how the tiles are stretched: through joints, stepping joints, vertical stretches, horizontal stretches, etc. . As an example, in the case of a stepping joint with a nominal size of 300 square units, the vertical width is 30 to 120 cm, preferably about 30 to 90 cm, and the horizontal width is about 30 to 150 cm, preferably about 30 to 120 cm, depending on the situation. It is desirable to adjust accordingly.

  After creating the reference line, apply the masking material. Examples of the masking material applicable in the present invention include an easily peelable paint, an adhesive tape, a masking material having an adhesive tape attached along one side of a rectangular vinyl sheet or paper sheet, and the like.

For example, the masking material sticking position is set as follows in consideration of the post-process.
Horizontal top edge: Masking the upper side of the reference line Others: Masking the lower side of the reference line Up / down direction Tiling from the right side: Masking the left side of the reference line Tiling the tile from the left side: Masking the right side of the reference line The masking material is stuck so that one side end thereof is in contact with the reference line. When an easy-release paint is used, a coating film is formed so as to cross the reference line, then a knife is put on the reference line to cut the coating film, and then a part of the coating film is peeled off as described above. Should be formed.

  The width of the masking is desirably a sufficient width at the boundary between the surface to which the tile is attached and the surface to which the tile is not attached so that the adhesive does not protrude from the surface to which the tile is not attached. It is desirable to do. In addition, since there is no problem even if the adhesive protrudes to the inside of the surface on which the tile is attached, it may be thin and is preferably about 5 cm or less from the viewpoint of resource saving.

As the adhesive usable in the present invention, organic adhesives such as acrylic, epoxy, urethane, acrylic silicone, and epoxy silicone, and known tile adhesives such as mortar can be used.
The adhesive can be applied by trowel application using a comb iron, a method using a continuous extrusion device such as a caulking gun, roll application by a roller, or spray application. In particular, roll application and spray application using a roller are preferable because the adhesive can be easily applied thinly and uniformly. In the case of the roll coating method, the viscosity of the adhesive is measured using a B-type viscometer No. 7 rotor, at 10 rpm, 1000 Pa · S or less, preferably 500 Pa · S or less, more preferably 300 Pa · S or less. 7 rotor, rotation speed 1 rpm, 50 Pa · S or more, preferably 100 Pa · S or more, more preferably 200 Pa · S or more. In order to apply with a roller, it is desirable to reduce the viscosity. However, by reducing the viscosity, the displacement resistance of the tile becomes a problem. It becomes possible to do. A preferable TI value is 4 or more and less than 20. The TI value is obtained by [viscosity at 10 rpm] / [viscosity at 1 rpm].

The adhesive coating thickness should be 0.5 mm or more and 3 mm or less in terms of dry or cured product. For the thickness of the adhesive, an average value is obtained by calculation from the volume change rate accompanying drying and curing, the amount of adhesion to the substrate, the application area, and the like.

  Following the application of the adhesive, the masking material is removed. The boundary line formed by removing the masking material is used as a guide for the tiling position.

Next, the tile attaching process will be described.
Place the tiles in place and stick them by pressing. In the boundary portion from which the masking material is removed, the tile side ends are pasted in parallel with the boundary line and the positions of adjacent tiles are aligned with each other. In that case, it is preferable that the distance from the boundary line to the tile side end has the same dimension as the tile joint. In this way, by using the boundary line as a guide, the positions of a plurality of tiles can be easily and accurately aligned.

  The process from application of the adhesive to tile attachment is repeated for each predetermined section. Masking can be done on a compartment-by-compartment basis, or all compartments can be masked at one time before applying the adhesive, but the adhesive application and tile pasting should be done from the top to the bottom to prevent the attached tile from being soiled with adhesive. It is desirable to do this.

  The tiles that can be used in the present invention are made of ceramics made of ceramics or glass, and can be used as glazed tiles or glazed tiles. For example, the granulated powder can be obtained by dry press molding in a mold after creating the granulated powder, and applying a glaze on the powder as needed and baking it. Moreover, lightweight tiles having a specific gravity of about 1 to 2 in which lightweight aggregates such as fly ash balloons, shirasu balloons, glass balloons, and foaming materials such as silicon carbide are added to the substrate can also be suitably used.

  It is desirable that the back surface of the tile has no back foot or has a back foot height of less than 1 mm. By doing so, even if the adhesive thickness is in the above range, the adhesive easily adheres over substantially the entire back surface of the tile, and sufficient adhesive strength is ensured.

  Further, a photocatalytic layer may be provided on the tile surface. By doing so, self-cleaning and antibacterial properties can be imparted to the tile surface.

  In the present invention, it is possible to attach each tile individually, but it is also possible to use a tile unit in which a plurality of tiles are arranged and fixed. Tile units include paper units with tile surfaces fixed to connected paper, resin units with tile side ends connected with synthetic resin, nets with the back side of tiles fixed to nets made of glass fiber or synthetic fibers, etc. Unit etc. are mentioned.
