Description

  The present invention relates to a method for constructing a tiled floor (in addition, the tile referred to in the present invention includes a tile-like stone plate in addition to a ceramic tile).

  Conventionally, when constructing a tiled floor of a general house or an apartment house, a tile base material is laid directly on the floor base material or through a floor heating panel, and a number of tiles are placed on the joint gap. The joint gap was filled with a cement joint material, a liquid or paste resin joint material, or a resin joint rod.

  By the way, in the said prior art, when using a cement type joint material for a joint gap, it is a deformation | transformation by the expansion | swelling by the shrinkage | contraction of a wooden floor base material and a tile base material, and the expansion and load by the heat | fever from a floor heating panel. , Cracks in joint materials, partial peeling and omission occur, and dirt tends to accumulate in those parts, which impairs the appearance, and if water is spilled, it penetrates downward and damages the floor heating panel. There is a problem of giving.

  Also, when using liquid or paste resin joint material, it is necessary to apply a curing tape to the tile surface in order to prevent the joint material from adhering to the tile surface and soiling it, which is troublesome. There is a point.

  In addition, when using resin joint rods, there are gaps between the tiles and the joint rods or in the joints between the joint rods. Thus, the same problems as in the case of the cement-based joint material occur.

  The problem to be solved by the present invention (object of the present invention) is to provide a method for constructing a tiled floor that has no problems as described above and has good workability.

  In the present invention, a tile base material is laid on a floor base material, and a large number of tiles are pasted with an adhesive with a joint gap therebetween, and a resin component in a weight ratio of 10 to 25 in the joint gap. %, And the remainder is filled with a resin joint material composed of a filler and a pigment, and the resin component has adhesiveness, and an epoxy resin, a modified silicone resin, a polyurethane resin, a silicone resin, or a modified silicone. -A tiled floor characterized in that it is an epoxy resin and the filler is a mineral powder, and the resin joint material is compressed or swung with a joint iron to fill the joint gap. A configuration method is provided.

  The resin joint material in the present invention (resin joint material containing 10-25% by weight of the resin component and the remainder comprising a filler and a pigment, etc.) has a filler (sand, etc.) slightly agglomerated into a granular material. It is in a state where the resin component is contained inside, and the property is very different from the conventional liquid or paste-like resin joint material, it is crunchy, and normally shows properties close to a granular material. However, when subjected to compression or rocking with a joint trowel, etc., each grain is consolidated and the resin component inside each grain exudes to the surface, etc., so that adjacent grains are joined together. It has the characteristic that becomes.

  And this resin joint material is the same as the conventional resin joint material in that it has good adhesiveness, high strength, and no water absorption or water permeability. Since it does not adhere, it is not necessary to stick a curing tape for preventing adhesion of the joint material to the tile surface as in the prior art when filling this into the joint part, and the workability is good.

  1 to 4 showing four examples of tile floors in the present invention, 1 is a tile, 2 is a resin joint material, 3 is an adhesive, 4 is a tile base material, 5 is a floor base material, 6 is a joist, 7 Is a heat insulating material, 8 is a large draw, 9 is a concrete floor, and 10 is a panel for floor heating.

  In the case of FIG. 1 and FIG. 3, the joist 6 is installed on the large pull 8, the heat insulating material 7 is filled between the joists 6 and 6, and the floor base material 5 is laid thereon. 2 and 4, the heat insulating material 7 is laid on the concrete floor 9, and the floor base material 5 is laid thereon.

  1 and 2, the tile base material 4 is laid directly on the floor base material 5, whereas in FIGS. 3 and 4, the tile base material 4 is placed on the floor base material 5. The tile base material 4 is laid through the floor heating panel 10.

  1 to 4 are configured by adhering a large number of tiles 1 on a tile base material 4 with adhesive joints 3 and filling the joint gaps with resin joint material 2. Has been.

  The tile base material 4 having a thickness of 3 to 12 mm is appropriate, and a fiber-reinforced cement board or the like is used outside the plywood.

  Adhesive 3 is a synthetic rubber-based latex type, a synthetic resin-based emulsion type, an epoxy-modified synthetic rubber-based latex type, a polyurethane resin-based, which have good adhesion to tile 1 and tile base material 4 and are durable. Modified silicone resin-based, silicone resin-based, modified silicone / epoxy resin-based, and epoxy resin-based materials are used, and are applied flatly to the tile base material 4 using a gold iron or using a comb iron. Can be applied with creases.

  The resin joint material 2 is composed of a resin, a filler, a pigment, an antifungal agent, and the like is an epoxy resin, a modified silicone resin, a polyurethane resin, a silicone resin, or a modified silicone / epoxy resin. No. 6-8 silica sand or inorganic powder such as calcium carbonate is used.

  The blending ratio of the resin joint material 2 is 10 to 25% of the resin component, 75 to 90% of the filler, 0.01 to 1% of the pigment and the antifungal agent, and the optimum blending ratio of the resin is resin. It is determined from the strength and workability required for the joint material 2.

  In addition, when the resin component is 25% or more by weight, it shows properties close to a paste-like resin joint material, and a large amount of resin adheres to the surface of the tile 1 to contaminate the surface, and 10% or less. As a result, the strength of the resin joint material 2 is weakened, the adhesive strength with the tile 1 is also lowered, and cracks are likely to occur in the resin joint material 2 due to drying shrinkage and deformation of the floor base material 5 and the tile base material 4. The waterproof property is deteriorated and the resin joint material 2 is easily soiled.

For example, a resin joint material consisting of 17% epoxy resin by weight, 82.98% silica sand (mixed equivalent of No. 6 and No. 7), and 0.02% black pigment has an adhesive strength to tile of 243 N / cm ² , Elongation 7.4%, Water Absorption 0.2%, Compared with cement-based joint material, it has stronger adhesive strength with tiles, larger elongation, elasticity, and waterproof Are better.

  As shown in FIG. 5, the resin joint material 2 is uniformly filled in the joint portion of the tile 1 while being compressed or rocked by the joint iron 11 or the like, and the excess resin joint material 2 is removed. In this case, since the resin joint material 2 does not adhere to the surface of the tile 1, as in the case of cement-based joint material, a long period of curing or a sponge moistened with water is used to remove the extra joint material. No wiping work is required, and improvement in work efficiency can be expected.

  The present invention provides a method for constructing a tiled floor with good workability.

It is a perspective view of an example of the tile floor in the present invention. It is a perspective view of another example similarly. It is a perspective view of another example similarly. It is a perspective view of another example similarly. It is a perspective view which shows the state at the time of filling of the resin joint material in the constituent method of the tile floor according to the present invention.
