Description

[Technical field]

[0001] The present invention relates to a semi-dry adhesive tiling method for attaching tiles to the exterior wall of a building by combining an organic adhesive with a mechanical fixing element. [Background technology]

[0002] Conventionally, wet and dry methods are known for tiling the exterior and interior walls of buildings. In the wet method, tiles are laid with mortar, whereas in the dry method, a base material with protrusions is fixed to the wall surface in advance, and the back side of the tile is fitted into it to be fixed. In other words, the tile is fixed to the wall surface by mechanically fitting into the base material, and an adhesive that plays an auxiliary role in preventing the tile from vibrating, etc., is sometimes used in combination with this. Bases for fitting tiles include metal channels, metal panels, extruded cement boards, and ceramic siding (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2001-271479 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned wet construction method, mortar is applied to the base wall surface and the tiles are directly attached to the base. Although this wet construction method provides the texture and durability of tiles, it has problems such as the possibility of tiles peeling off due to deterioration of the mortar, and an increase in the weight acting directly on the wall surface.

[0005] On the other hand, in the dry construction method, for example, a base material called base siding is fixed to the wall surface, and then the tiles are attached so that they are supported by the base material. This dry construction method has the advantages of being able to achieve a variety of designs and textures, reducing the weight of the wall compared to wet tiles, reducing the risk of poor construction or peeling, improving construction efficiency, and not requiring special techniques. On the other hand, this dry construction method has a structure in which the tiles are supported only by the base material, so there is a problem that if the base material deteriorates, the tiles are more likely to peel off.

[0006] Therefore, an object of the present invention is to provide a tile installation structure and method that can more reliably prevent tiles from falling off even if the base material deteriorates when attaching tiles to a wall surface. [Means for solving the problem]

[0017] Hereinafter, with reference to the accompanying drawings, an embodiment of a tiling structure and a tiling method according to the present invention will be described in detail. Figs. 1 to 3 show the tiling structure and method according to this embodiment, and Fig. 4 shows the configuration of the tiling structure according to this embodiment. Note that the embodiment shown below is an example of an apparatus for embodying the technical idea of ​​this invention, and the technical idea of ​​this invention does not limit the material, shape, structure, arrangement, etc. of each component part to those described below. The technical idea of ​​this invention can be modified in various ways within the scope of the claims.

[0018] (Tile structure configuration) In this embodiment, the tile installation structure and construction method of the present invention will be described by taking as an example a case where it is applied to siding installation on the exterior wall of a building. In this embodiment, in tile installation on the exterior wall of a building, as shown in Fig. 1, a siting panel 3 is attached to the surface of an exterior wall 4 as a base material for tiles 2, and the siting panel 3 plays a role of supporting the tiles 2.

[0019] In this embodiment, the exterior wall 4 is made of lightweight aerated concrete that is cured with high temperature and high pressure steam, known as ALC (Autoclaved Lightweight Aerated Concrete). The siting panel 3, which serves as a base material, is attached onto the ALC exterior wall 4, and the tiles 2 are supported via the siting panel 3.

[0020] The tiles 2 are rectangular or other shaped components having a specified thickness, and various types can be used depending on the installation location, design, budget, etc., such as ceramic tiles or porcelain tiles made by baking clay at high temperatures and coated with a glassy glaze, stone tiles made from natural stone such as marble, granite, slate, limestone, or travertine, and glass tiles made from glass-based materials.

[0021] On the other hand, in the tiled structure 1 of this embodiment, the siting panel 3 is a base material that is fixed to the wall surface of the exterior wall 4 and has a flat portion parallel to the wall surface, and examples of such siding include "resin-based siding" made from plastic or vinyl, "wooden siding" made from wood or wood-based materials, "ceramic siding" made by molding and hardening materials such as cement, sand, and cellulose fiber, and "metal-based siding" made from aluminum, steel, etc.

[0022] The siting panel 3 can be fixed to the wall surface by, for example, using nails, which are driven directly into the studs of the wall, and each nail is positioned at the top of each siding panel and covered by the next panel, so that it is not visible from the outside when the panel is completed. Other fixing methods include using screws, which can be used for metal and vinyl siding, and clips and brackets, which can be used to install the siding panel a little away from the wall surface depending on the siding system. In addition, lightweight siting panels 3 can be directly attached to the wall surface using adhesive. These fixing methods are appropriately selected depending on the siding material, wall structure, and construction conditions.

[0023] Moreover, the siting panel 3 according to this embodiment has a flange 32 formed on its front surface as an engagement portion that engages with the tile 2. This flange 32 extends horizontally and is formed in multiple stages to fit the height (vertical width) of the tile 2. That is, the tiles 2 are arranged horizontally on the front surface of the siting panel 3, which is the base material, and the multiple stages of flanges 32 protrude so as to sandwich the upper and lower parts of the tiles 2 arranged horizontally, and each tile 2 is engaged with the siting panel 3 by sandwiching the upper and lower parts of each tile 2 between the upper and lower flanges 32.

[0024] Furthermore, an opening 31 that connects the front and back is formed in the flat portion of the siting panel 3 according to the position where the tile 2 is attached. This opening 31 is formed by hollowing out the flat portion of the siting panel 3, and when the siting panel 3 is installed on a wall surface, the wall surface is exposed through the opening 31.

[0025] 4, adhesive (tile bond) is filled through the opening 31 so as to reach the wall surface of the exterior wall 4, and the tile 2 is engaged with a flange 32 formed on the front side of the siting panel 3 to form an adhesive section 20. This adhesive section 20 bonds the back surface of the tile 2 to the wall surface of the exterior wall 4 through the opening 31 in the space between the back surface of the tile 2 engaged with the siting panel 3 and the wall surface of the exterior wall 4, and also bonds the back surface of the tile 2 to the front side of the siting panel 3.

[0026] The adhesive used in this adhesive joint 20 is selected mainly depending on the material of the tile, the condition of the surface (base) to which the tile is attached, and the construction environment; for example, cement-based tile adhesive (Thinset), mortar, epoxy adhesive, etc. can be used.

[0027] After the tiles 2 are fixed to the sitting panel 3, the gaps between the tiles 2 are filled with joint bond 21. This joint bond 21 is used to fill the gaps (joints) between the tiles 2, and absorbs minute movements between the tiles 2 to prevent cracks and chips. It is a material used to prevent water and dirt from penetrating under the tiles and to give the tiles a beautiful appearance. There are various types of joint bond, such as cement-based, epoxy-based, urethane-based, and silicone-based, and they can be selected appropriately depending on the type of tile, the construction environment, and the expected performance.

[0028] (Tile installation method) The tiling structure described above can be constructed by the tiling method of the present invention. Figure 6 shows the procedure of the tiling method according to this embodiment. Note that the processing procedure described below is merely an example, and each process may be modified as much as possible. Also, for the processing procedure described below, steps may be omitted, replaced, or added as appropriate depending on the embodiment.

[0029] First, the base of the exterior wall 4 made of ALC is finished (S101). This ensures the durability and safety of the building and enables stable installation of the siting panel 3. Specifically, any unevenness on the surface of the ALC is removed by grinding, a special primer is applied to prepare the base, and weather-resistant and stain-resistant exterior wall paint is applied as necessary, or a waterproof sealant is applied to the joints between the ALC panels.

[0030] Next, a base material fixing process is performed in which the siting panel 3 as a base material is fixed to the exterior wall 4 (S102). There are various types of siting panels 3, such as resin-based, wooden, ceramic-based, and metal-based, and the selection is made based on the design of the building, the characteristics that need to be protected, and the budget. The siting panel 3 is fixed to the exterior wall 4 using nails, screws, clips, and brackets, or, in the case of certain lightweight siding, it may be directly attached to the wall surface using an adhesive.

[0031] Thereafter, a tile engagement process is performed in which the tile 2 is fixed to the siting panel 3 using tile bond (S103). In this process, while engaging the tile 2 with the flange 32, the tile bond is injected through the opening 31 between the rear surface of the siting panel 3 and the surface of the exterior wall 4 to form an adhesive joint 20 that bonds the two together. There are various types of tiles 2, such as ceramic tiles, porcelain tiles, stone tiles such as marble, granite, slate, limestone, and travertine, and glass tiles, and the type is selected according to the installation location, design, budget, and the like.

[0032] Next, a joint bond is applied to fill the gaps between the tiles 2 (S104). Joint bonds include cement-based, epoxy, urethane, silicone, etc., and are selected based on the characteristics of each joint bond depending on the type of tile, the construction environment, and the expected performance. Then, the construction is completed by performing a finishing process (S105). This finishing process includes a final check to ensure that the tiles are correctly positioned and that all necessary adhesives and joint bonds have been properly applied and dried.

[0033] (Action and effect) According to this embodiment, by including a step of engaging the tile 2 with the flat surface of the siting panel 3, the position of the tile 2 is stably supported by the siting panel 3, improving the flatness and aesthetic appearance of the entire wall surface. This makes it possible to significantly reduce the risk of the tile 2 falling off without impairing the aesthetic appearance of the exterior and interior walls.

[0034] Furthermore, according to this embodiment, adhesive is filled through the opening 31 so as to reach the wall surface of the exterior wall 4, and the back surface of the tile 2 is bonded to the wall surface, and the back surface of the tile 2 is bonded to the front side of the sit- ing panel 3, so that the tile 2 is fixed from both the wall surface and the base material. As a result, even if the sit- ing panel 3 deteriorates, support from the wall surface is maintained, and it is possible to more reliably prevent the tile 2 from falling off.

[0035] Furthermore, according to this embodiment, the wall surface of the exterior wall 4 and the tile 2 are directly bonded together using adhesive, which significantly reduces the moisture remaining between the siting panel 3 and the exterior wall 4 and makes it possible to suppress deterioration of the base material.

[0036] Furthermore, according to this embodiment, by bonding both the siting panel 3 and the surface of the exterior wall 4, and the tile 2 and the siting panel 3, strength against contraction and expansion due to temperature changes in the space is improved, and cracks in the tile 2 and deformation of the siting panel 3 can be prevented.

[0037] As described above, according to this embodiment, when attaching tiles 2 to the surface of an exterior wall 4, even if the siting panel 3 deteriorates, it is possible to more reliably prevent the tiles 2 from falling off, which significantly solves the problems associated with dry tile installation methods and improves the durability and safety of tile installation.

[0038] (Example of change) The present invention is not limited to the above-described embodiments, and the components can be modified without departing from the spirit of the invention. Various inventions can be created by appropriately combining the components disclosed in the above-described embodiments. For example, some components may be deleted from all the components shown in the embodiments.

[0039] 5, the ends 5a, 5b of adjacent tiles 5, 5 may be overlapped with the flange 32 of the engagement portion sandwiched therebetween to form an overlapping portion 50 that covers the flange 32. In this case, in the above-mentioned tile engagement step, the ends 5a, 5b of adjacent tiles 5, 5 are overlapped with the flange 32 sandwiched therebetween to form the overlapping portion 50, and the flange 32 of the engagement portion is covered by this overlapping portion 50. At this time, an adhesive or joint agent may be applied or injected into the overlapping portion 50. [Explanation of symbols]
