BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a construction for attaching a tile to a ground surface.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 2, a tile construction structure is such that a tile 1 is strongly adhered to a surface 2a of a concrete surface of an inner wall, an outer wall or a floor or a mortar substrate 2 by a pasting mortar layer 3. Some are stuck.

[0003]

[Problems to be solved by the invention] By the way, the groundwork 2
Cracks 4 occur due to temperature differences, road vibrations, or land subsidence. When this crack 4 occurs, the ground 2
From the mortar layer 3 to the tile 1. This transmitted force may be greater than the strength of the tile 1. In this case, cracks 5 occur in the tile 1 due to insufficient strength. The crack 5 of the tile 1 impairs the beauty of the tile wall surface and causes problems such as peeling of the tile. Especially large tiles (300 mm x 30
This problem is conspicuous in the case of 0 mm square or more. Even if the tile 1 where the crack 5 is generated is replaced, the crack 5 still occurs at the same location.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a tile construction structure which does not cause cracks in tiles even if cracks occur in the groundwork.

[0005]

Means adopted by the present invention are as follows: in a construction structure in which a tile is attached to a base surface, a modified silicone-based, elastic mortar or elastic epoxy is applied to the base surface.
When an adhesive with elasticity is hardened,
Soft cloth pre-impregnated with an adhesive into an auxiliary sheet such as a nonwoven fabric
Corrosion reinforcing plate is adhered through an adhesive layer of soft consisting over preparative like adhesive, an epoxy-based or case to the corrosion resistance reinforcement plate
Hardened when mortar mixed with synthetic polymer emulsion is cured
Tiles through an adhesive layer of rigid made of adhesive made that it is the construction structure of the tile, characterized in that it is stuck.

[0006]

[Operation] The corrosion-resistant reinforcing plate and the tile are joined with a hard adhesive layer to form an integrated laminate. Therefore, the laminate has much higher mechanical strength such as bending or tension than the strength of the corrosion-resistant reinforcing plate and the tile alone. When a crack occurs on the lower ground, the soft adhesive layer that bonds the ground surface and the corrosion-resistant reinforcing plate is deformed in accordance with the occurrence of the crack because the portion corresponding to the crack occurrence location and the vicinity thereof are extended. However, even when the laminate composed of the corrosion-resistant reinforcing plate and the tile receives an external force from the deformable soft adhesive layer, it is not easily damaged because of its large mechanical strength and against the external force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tile construction structure according to the present invention (hereinafter referred to as "the present invention structure") will be described based on an embodiment shown in FIG.

In the embodiment of the present invention structure, a corrosion-resistant reinforcing plate 8 is adhered to a base surface 2a via a soft adhesive layer 7, and the tile 1 is bonded to the corrosion-resistant reinforcing plate 8 via a hard adhesive layer 9. Is affixed.

The base 2 is formed of cast concrete or mortar on the inner wall, outer wall or floor, and its surface serves as a base surface 2a. In order to improve the adhesive strength of the adhesive layer 7, the lower ground 2a may be provided with an uneven portion (not shown) as necessary.

The soft adhesive layer 7 is made of a modified silicone resin, elastic mortar, elastic epoxy, or other such adhesive which is elastic when cured, or a soft sheet obtained by impregnating a reinforcing sheet such as a nonwoven fabric with such an adhesive in advance. It is made of a sheet-like adhesive and has a layer thickness T of about 1 to 5 mm. The adhesive layer 7 is provided on all or a portion between the base surface 2a and the corrosion-resistant reinforcing plate 8.

The corrosion-resistant reinforcing plate 8 is made of an aluminum plate, a fiber-reinforced plastic plate, a stainless steel plate, or the like, and has a plane size equivalent to one or several tiles 1. In order to improve the adhesive strength between the corrosion-resistant reinforcing plate 8 and the adhesive layer 7 and the adhesive layer 9, an uneven portion (not shown) may be formed on the surface of the corrosion-resistant reinforcing plate 8 to improve the adhesive biting. .

The hard adhesive layer 9 is made of an adhesive which becomes hard when cured, such as a mortar mixed with an epoxy-based or synthetic polymer emulsion. The adhesive layer 7 is provided on all or a portion between the corrosion-resistant reinforcing plate 8 and the tile 1.

The tile 1 is a large or mosaic tile made of porcelain or the like, and has a dovetail-shaped projection (not shown) on the back side of the adhesive in order to improve the adhesive strength with the adhesive layer 9. (Omitted) are provided as necessary.

Next, a procedure for constructing the structure of the present invention will be described. (Construction Procedure 1) First, an adhesive which is elastic when hardened is applied to the ground surface 2a or the corrosion-resistant reinforcing plate 8, and then the corrosion-resistant reinforcing plate 8 is bonded to the ground surface 2a, and the adhesive is hardened to be soft. Adhesive layer 7
To form Next, an adhesive which hardens when cured to the corrosion-resistant reinforcing plate 8 or the tile 1 is applied.
To form a hard adhesive layer 9 by curing the adhesive to complete the construction. Between the adjacent corrosion-resistant reinforcing plates 8 and 8 and between the adjacent tiles 1 and 1, an appropriate space S for expansion and contraction absorption is provided, and joint filling 11 is performed.

(Procedure 2) First, an appropriate number of laminates 10 formed by integrating the corrosion-resistant reinforcing plate 8 and the tile 1 are prepared in advance. The laminate 10 is manufactured by applying an adhesive that becomes hard when cured to the corrosion-resistant reinforcing plate 8 or the tile 1, then bonding the tile 1 to the corrosion-resistant reinforcing plate 8 and curing the adhesive to form a hard adhesive. This is performed by forming the layer 9. Next, an adhesive which is elastic when hardened is applied to the base surface 2a or the corrosion-resistant reinforcing plate 8 of the laminate 10, and then the laminate 10 is bonded to the base surface 2a, and the adhesive is cured to form a soft adhesive. Forming the agent layer 7,
Complete the construction. In the same manner as above, a space S for absorbing expansion and contraction is provided between adjacent corrosion-resistant reinforcing plates 8 and 8 and between adjacent tiles 1 and 1, and joint filling 11 is performed.

In the structure of the present invention constructed as described above, when the crack 4 occurs on the ground surface 2a, the portion of the soft adhesive layer 7 corresponding to the crack occurrence location and the vicinity thereof is extended, so that the soft adhesive layer 7 is deformed following the crack 4. However, the laminate 10 composed of the corrosion-resistant reinforcing plate 8 and the tile 1 is not easily damaged even if it receives an external force from the deformable soft adhesive layer 7. Because the laminate 10 is
Since the corrosion-resistant reinforcing plate 8 and the tile 1 are joined by a hard adhesive layer 9 and integrated, the mechanical strength such as bending or tensile strength is much higher than the strength of the corrosion-resistant reinforcing plate 8 and the tile 1 alone. It is because it becomes large. Therefore, the propagation of the crack 4 on the base surface 2a is absorbed by the soft adhesive layer 7 and blocked by the corrosion-resistant reinforcing plate 8, and does not reach the tile 1. Suppose that tile 1 is a large tile (300m
(m × 300 mm square or more), the propagation of the crack 4 does not reach the tile 1.

[0017]

As described in detail above, the present invention has the following practical effects. Underground crack propagation is absorbed by the soft adhesive layer and blocked by the corrosion resistant stiffeners and does not reach the tiles.
As a result, the present invention can provide a beautiful and safe tiled wall surface in which cracks do not occur on the tiles even if cracks occur on the groundwork. The laminate in which the tile and the corrosion-resistant reinforcing plate are joined by a hard adhesive layer and integrated can improve the bending strength to about 2 to 7 times compared to the single strength of the tile.
As a result, the present invention enables thin large tiles, which cannot be used as floor tiles, to be used as floor tiles.
