Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mechanically improves the adhesive strength of a unit tile when a plurality of tiles are connected to each other to form a unit tile on a wall surface by using a metal fitting. It relates to a wet construction structure.

[0002]

2. Description of the Related Art As a method of constructing this type of unit tile, the method shown in the vertical sectional views of FIGS. 6 and 7 is known. In this conventional unit tile 1, a synthetic fiber non-woven fabric 3 made of polypropylene is arranged on the back side of a large number of tiles 2 arranged at predetermined joint intervals, and a polymer-containing Portland cement mortar is provided on the entire surface of the non-woven fabric 3. Is impregnated to connect the tiles 2. Although kraft paper 4 or the like is attached to the front surface side of the unit tile 1, this is not essential to the unit tile 1 and may be omitted. Front side kraft paper 4
The unit tile 1 is too soft for each tile 2
This is to improve the rigidity of the whole and to make it easy to handle, since they move apart. Thus, in the conventional construction of the unit tile 1, first, the mortar 6 for sticking is applied to the wall surface 5 of the building body by a predetermined thickness, and the back surface side of the unit tile 1 is pressed together with the non-woven fabric 3 to the mortar 6 and stuck. I'm wearing it.

[0003]

However, in the conventional method of constructing the unit tile 1, the tiles 2 are connected to each other with the polymer-containing Portland cement on the entire surface of the non-woven fabric 3 disposed on the back side. This is done by impregnation. Therefore, after the Portland cement containing the polymer is hardened, the permeability of the non-woven fabric 3 is lost, and when the unit tile 1 is attached to the mortar 6 for attachment of the wall surface 5, the mortar 6 for attachment is Non-woven fabric 3
It will not wrap around to the back side of the tile.

That is, the attachment of the unit tile 1 to the wall surface 5 is performed only by the adhesive force at the interface between the nonwoven fabric 3 impregnated with Portland cement containing the polymer and the attachment mortar 6 of the wall surface 5. The tiles 2 and the mortar 6 for sticking are not directly bonded. Therefore, the adhesive strength to the wall surface 5 of each tile 2 may be weakened due to the difference in the construction site or the individual skill level of the construction operator, and the unit tile 1 as a whole may peel off or fall. There was a risk of an accident.
