Abstract

PURPOSE:To heighten the durability of tilting finishing for the surface of an inorganic material such as a reinforced concrete wall, a PC panel wall, or an ALC panel wall, or of an organic material, by a method wherein an adhesive property is made better when tiles or the like are stuck on the surface of a building frame consisting of the inorganic material, such as concrete, or wood, and such troubles that storm water permeates through tile joints, that injurious gas enters therethrough, that the storm water leaks in a room owing to cracks on the inorganic material, and that the tiles peel off, can be prevented. CONSTITUTION:A special sheet A wherein space lattice-shaped nonwoven fabrics made of a polymer resin are stuck on both sides, surface and reverse, of a sheet made of a polymer resin excellent in gasproof, waterproof and elastic properties, is pasted on the surface of a building frame, such as a reinforced concrete wall, a PC panel wall, an ALC panel wall or a plywood wall, using polymer mortal 6. After that, bed mortal 7 for tilting is applied on the special sheet A and the finishing work of sticking tiles 8 is done thereon.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of attaching a surface material, which is a finishing material such as a tile, to the surface of an inorganic material wall such as a reinforced concrete wall, a PC panel wall or an ALC panel wall, which is a wall surface of a building. Alternatively, the present invention relates to a surface material finishing method in which the surface of a wood wall such as plywood is tiled.

[0002]

2. Description of the Related Art Conventionally, when a tile is attached to the surface of an inorganic material such as a reinforced concrete wall, a PC panel wall, or an ALC panel wall, mortar is applied to the surface of the inorganic material such as a reinforced concrete wall, It is known to attach tiles and make a joint finish between the tiles.

[0003]

However, in the tiled finishing method in the above-mentioned prior art, neutralization of the skeleton concrete, rusting of the reinforcing bar, inorganic material due to infiltration of rainwater from tile joints, invasion of harmful gas, etc. Water leaks into the room due to cracks in the room, tile peeling, etc.
There was a drawback that the durability of the building was reduced. In view of these circumstances, the present invention provides a special sheet formed by adhering a three-dimensional lattice-shaped polymer resin non-woven fabric on both the front surface and the back surface of a polymer resin sheet having excellent gas barrier property, waterproof property, and stretchability. After sticking to the structure of the building using mortar,
It is an object of the present invention to provide a surface material attaching finishing method for performing tile finishing by applying a finishing material such as a tiled base mortar.

[0004]

The present invention adopts the following technical means in order to solve the above problems. In the invention according to claim 1, on the surface of a reinforced concrete wall, a PC panel wall, an ALC panel wall, a plywood wall or the like, a gas barrier property,
A special sheet in which a three-dimensional lattice-shaped polymer resin non-woven fabric is adhered to both the front and back sides of a polymer resin sheet with excellent waterproofness and stretchability is attached to the building frame using polymer mortar, and then tiled. Adopting a technical means of applying upholstery foundation mortar and applying tile finish. According to the invention of claim 2, in addition to the invention of claim 1, a three-dimensional lattice-like structure is formed on both the front and back surfaces of a building wall and a polymer resin sheet excellent in gas barrier property, waterproof property, and stretchability. We adopted the technical means of providing a communication hole in the building wall so as to dissipate the water and the air expansion pressure staying at the interface of the special sheet to which the polymer resin nonwoven fabric is adhered.

[0005]

As a result of adopting the above technical means, when the surface of the inorganic material is tiled, the surface of the polymer resin sheet, which is a special sheet excellent in gas barrier property, waterproof property and stretchability, is obtained. Since the three-dimensional lattice-shaped polymer resin non-woven fabric is adhered to both sides of the back and the back surface, the three-dimensional lattice-shaped polymer resin non-woven fabric (for example, polymer mortar can penetrate into the cavity because it has a cavity like a loofah) If you apply a polymer mortar that is the base mortar inside,
This polymer mortar penetrates into the voids of the three-dimensional lattice. By this action, the primer is applied to the surface of the inorganic material such as concrete, after drying, the polymer mortar is applied, and the special sheet is attached, so the adhesion with the surface of the inorganic material becomes good, and the penetration of rainwater from the tile joints. The durability of the tiled finish applied to the surface of inorganic materials such as reinforced concrete walls, PC panel walls, ALC panel walls, etc. by preventing the entry of harmful gas, water leakage into the room due to cracking of inorganic materials, peeling of tiles, etc. It has the effect of increasing the level.

Type primer etc. The tiles 8 include fired tiles such as porcelain tiles and ceramic tiles.

Next, since the degree of penetration of carbon dioxide into the inorganic material 4 such as concrete of the skeleton 3 has a great influence on the corrosion of the reinforcing bars, the test results will be described below. 1) surface (30 x 30c)
m, smooth surface), the polymer paste (see Table 2) was applied to a thickness of 1 mm, and immediately the polymer paste was applied to the back surface layer in advance.

Rainfall, black panel temperature 60 ° C) were carried out and immediately a neutralization acceleration test (CO2 concentration of the test body was 5%, 30 ° C,
After exposure for 30 days at 60% Rh, the cross-section of the test body was coated with a phenolphthalein solution to measure the neutralization depth and observe the tile adhesion state).
