Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a floor surface that requires a drainage slope, such as a bathroom floor or a toilet floor, with a tile surface.

Traditionally, the construction method for sloped tile floors is the first method.
As shown in Figure A, concrete 2 is poured on top of the well-trodden base 1, and mortar is applied to the completely hardened top surface 2a of the concrete 2 so that it slopes downward toward the drain pipe 3. As shown in Figure B, tiles 5, 5, etc. are adhered to the upper surface 4a of the completely hardened base mortar layer 4, and finally, the joints are filled 6 to form a sloped tile floor. It was a 7th grade. However, conventional construction methods had the following drawbacks.

○A Base mortar 4 is applied so that it slopes downward toward the drain pipe 3, and the hardened base mortar 4
To attach tiles 5, 5... to the top surface 4a of
Because it requires a high degree of skill, it has the disadvantage that only tile craftsmen can do it.

○B The work of applying the base mortar 4 to form the slope surface can only be done after the sacrificial concrete 2 has completely hardened because the worker needs to stand on the sacrificial concrete 2. Furthermore, the work of pasting the tiles 5, 5, . . . can only be done after the base mortar 4 has completely hardened, since it is necessary for the worker to stand on the base mortar 4. Since it takes a long time for the concrete and mortar to harden, it takes a long time to apply the base mortar 4, and it takes a long time to paste the tiles 5, 5... The subsequent construction period required 6 to 7 days, resulting in a long construction period.

In order to solve the above-mentioned drawbacks, the present invention aims to provide a method for constructing a sloped tile floor surface that can be constructed in a short period of time even by non-skilled workers.

The gist of the present invention is a method for constructing a sloped tile floor surface, in which a sacrificial concrete is placed in a floor forming area, a self-leveling material is poured into the surface of the sacrificial concrete to form an intermediate layer with a horizontal surface,
The lower surface of a tile panel whose upper surface is formed of an inclined tile surface is adhesively fixed onto the surface of the intermediate layer.

Hereinafter, the present invention will be explained based on an example of bathroom floor construction shown in FIGS. 2A to 2C. The first step is
As shown in Fig. A, concrete 10 (for example, 1 part by weight of cement, 2 parts by weight of sand, 3 parts by weight of gravel, A kneaded material consisting of parts by weight and an appropriate amount of water is poured to an appropriate thickness (for example, 50 mm). 21 in the figure is a bathtub.

In the second step, after the curing of the sacrificial concrete 10 has progressed, an appropriate amount (for example, 5.0
Kg/m ² ) to form the intermediate layer 12. The poured self-leveling material 11 progresses in hardening while naturally forming a horizontal and smooth surface 12a due to its self-flowing property. The self-leveling material 11
is Portland cement, aggregate made of silica sand, etc., and a fluidity improver (for example, one or more of lignin-based sulfonates, polycyclic aromatic sulfonates, melamine-based sulfonates, polyoxyethylene ether, etc.). an AE agent consisting of a seed mixture);
It consists of a material kneaded with water, has good self-flowing properties at the initial stage after kneading, and hardens over time. Furthermore, to specifically explain an example of the self-leveling material 11, the self-leveling material 1
1 is 40 parts by weight of Portland cement and 7 parts by weight of silica sand.
25 parts by weight of No. 8, 25 parts by weight of silica sand No. 8, and AE agent.
It is obtained by kneading 10 parts by weight and 30 parts by weight of water using an electric mixer for about 5 minutes.

In the third step, appropriate places on the horizontal lower surface 13b of the tile panel 13 are coated with epoxy on the horizontal and smooth surface 12a of the mortar layer 12 formed as the self-leveling material 11 hardens (for example, 12 hours after pouring). Adhesive and fix with adhesive 14 (B in the same figure)
refer. The tile panel 13 is manufactured in advance at a factory, and as shown in FIG.
A tile group 16 is adhered 17 to the inclined surface 15a of No. 5 with an epoxy adhesive or the like, forming a tile surface 13a having an appropriate slope ratio (for example, 15/1000 to 10/1000) with respect to the flat lower surface 13b. . Foundation 15
is made of foamed rigid vinyl chloride, foamed urethane, foamed polystyrene, etc. with an appropriate thickness (for example, 30 to 50 mm), and is formed into a flat back surface 15b and an inclined surface 15 by an appropriate method such as pressure molding or grinding.
a is formed. The tile panel 13 includes
An opening 13c for inserting a drain pipe is formed in advance as necessary.

In the final step, as shown in FIG. The lower end is inserted, and a sealant 20 is filled between the perforated plate holder 19 and the tile 16'. Furthermore, before or after attaching the perforated plate holder 19, the tile group 16 of the tile unit 13 is filled with joints 6 (see FIG. B) as necessary.

Although the above embodiment describes the construction of a bathroom floor, the present invention is not limited to bathroom floor construction in any way, but is applicable to sloped tile floors such as toilet floors, entrance floors, terrace floors, etc. Applicable to construction that requires a surface. In addition, when a drainage hole is not required on the floor surface, the tile panel 13 is omitted from the illustration.
It may also be formed with a tile surface that is sloped in one direction.

As described in detail above, the method for constructing a sloped tile floor surface according to the present invention has the following excellent effects.

The work of forming the surface of the intermediate layer does not require any high level of skill as it is possible to obtain a naturally level surface by simply pouring a self-leveling material onto the surface of the concrete. Further, the tile pasting operation does not require any high level of skill since a sloped tile surface can be obtained by simply adhesively fixing the lower surface of the tile panel onto the hardened surface of the intermediate layer. Therefore, it can be easily installed even without the tile craftsman required in the past.

The horizontal surface of the intermediate layer is formed naturally by simply pouring the self-leveling material onto the surface of the concrete, so it can be formed in an extremely short time compared to the conventional troweling process of applying the base mortar. It becomes possible.

When pouring the self-leveling material, there is no need for an operator to stand on the waste concrete, so the self-leveling material can be poured after the waste concrete has semi-hardened. As a result, the intermediate layer can be formed in a shorter time than the conventional formation of the base mortar layer, which is performed after the concrete has completely hardened.

The tile pasting work can be completed in a shorter time than conventional tile pasting work because a sloped tile surface can be obtained by simply gluing and fixing tile panels that have been pre-fabricated in a factory to the surface of the intermediate layer.

The construction period can be reduced to 3 to 4 days due to the above-mentioned synergistic effects, and can be shortened by 3 to 4 days compared to the conventional method.
