Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface treatment method for a PC board pre-tiled tile which is fixed to the surface of a precast concrete (PC) board.

[0002]

2. Description of the Related Art Conventionally, it has been as shown in FIG. FIG.
In the figure, 1 is a PC board pre-tiled tile formed in a rectangular or square shape by a mold, and a tile 3 made of stoneware having some permeability or porcelain having no permeability is provided on the upper surface of the PC board 2 at a predetermined pitch. Laid and secured with each tile 3
A joint 4 made of concrete is filled in the gap. Reference numeral 5 is an iron angle fixed to the steel frame of the building.

[0003]

In the above-mentioned conventional ones, the color of the joint 4 is different among the PC board pre-tiled tiles 1, the efflorence is generated in the joint 4 portion, and the appearance is spoiled, or the joint is deteriorated. There was a defect that rainwater penetrated into the area 4 and was freeze-expanded to cause damage. It is an object of the present invention to obtain a novel method for surface-treating a PC board pre-tiled tile that solves the above-mentioned drawbacks.

[0004]

The present invention is configured as follows to achieve the above object. That is, P
After applying a permeable water-absorption preventing material and then a pigment having a predetermined color to the entire surface of the tiles and joints of the C plate pre-tiled tile, the pigment applied to the surface of the tile is removed, and then a transparent coating film type is applied. A waterproof material is applied to cover the pigment adhered to the joint surface between the tiles. Also,
A pigment having a predetermined color is applied to the entire surface of the tiles and joints of the PC board pre-tiled tile, and then a penetrating water-absorbing material is applied, and then the pigment applied to the surface of the tile is removed, and then a transparent coating film A waterproof material is applied to cover the pigment adhered to the joint surface between the tiles.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. First, a PC using tiles that have some water absorption
The surface treatment of the board-end tile will be described. In FIG. 1, reference numeral 10 denotes a PC plate pre-mounted tile formed in a rectangular or square shape by a mold (not shown), and a tile 12 made of a stoneware having a slight water absorption property on the upper surface of a PC (precast concrete) plate 11 is predetermined. The tiles 12 are laid and fixed at a pitch, and the joints 13 made of concrete, which are a part of the PC board 11, are filled between the tiles 12.

First, as shown in FIG. 1, the entire upper surface of the PC board prefabricated tile 10, that is, the tile 12 and the joint 1.
A transparent water-permeable material for preventing water absorption, for example, a water-absorbing material 14 made of a silicon-based water-repellent material is applied and dried on the upper surface of 3 to impart the water-absorption preventing property. Next, as shown in FIG. 2, the entire upper surface of the PC board pre-mounted tile 10, that is, the water-absorption preventing material 14 described above.
After the inorganic pigment 15 having a predetermined color is applied to the entire upper surface of the tile 1 and dried, as shown in FIG.
Only the pigment 15 applied to the upper surface of 2 is removed by wiping with a cloth or the like.

Next, as shown in FIG. 4, a transparent waterproof film-type waterproof material, for example, a waterproof film-type waterproof material 16 made of elastic acrylic / silicone resin 16 is applied to the entire upper surface of the PC board prefabricated tile 10. The upper surface of the pigment 15 adhering to the upper surface and the upper surface of the joint 13 is covered to complete the surface treatment of the PC board prefabricated tile. In FIGS. 1 to 4, 17 is P
It is an iron angle projecting to the back surface (downward) side of the C plate 11, and is for fixing the PC plate pre-mounted tile 10 to a steel frame of a building or the like.

Next, the surface treatment of the PC board pre-mounted tile using a non-water-absorbing tile will be described. In FIG. 5, reference numeral 10 'denotes a PC plate pre-mounted tile formed in a rectangular or square shape by a mold (not shown), and a tile 12' made of porcelain having no water absorption is predetermined on the upper surface of the reinforced concrete PC plate 11. The tiles 12 'are laid and fixed at a pitch, and the joints 13 made of concrete, which are a part of the PC board 11, are filled between the tiles 12'.

First, as shown in FIG. 5, an inorganic pigment 15 having a predetermined color is applied to the entire upper surface of the PC board prefabricated tile 10 ', that is, the upper surfaces of the tile 12' and the joints 13, and after this is dried. Then, the water absorption preventing material 14 similar to that of the first embodiment described above is applied to the entire upper surface thereof (FIG. 6).
In this case, since the pigment 15 has permeability, the water-absorption preventing material 14 passes through the pigment 15 and permeates into the joint 13 part. Then, as shown in FIG. 7, the pigment 15 and the water absorption preventing material 14 applied to the upper surface of the tile 12 ′ are wiped and removed with a cloth or the like. In this case, since the tile 12 'does not have water absorption, the adhesion of the pigment 15 and the water absorption preventing material 14 is weak, and these can be easily removed.

Then, as shown in FIG. 8, the same waterproof film 16 as in the first embodiment is applied to the entire upper surface of the PC board pre-tiled tile 10 ', and the upper surface of the tile 12' and the joint 13 are coated. Pigment 15 and water absorption preventing material 14 attached to the upper surface
To complete the surface treatment of the PC board pre-tiled tile. 5 to 8, the portions having the same reference numerals as those in FIGS. 1 to 4 have the same structure as those in FIGS. 1 to 4, and therefore description thereof will be omitted.

According to the above-mentioned embodiment, the joints 13 of the tiles preliminarily attached to the PC boards are unified into a predetermined color by the pigment 15, and the permeation of the water-absorption preventing material 14 and the water-proof coating material 1 are carried out.
With the coating of No. 6, efflorence does not occur in the joint portion and rainwater does not penetrate, and the appearance and durability of the joint 13 are improved. Further, since the upper surface of the tile 12 (12 ') is also covered with the coating film-type waterproof material 16, rainwater does not penetrate even if an inexpensive tile having a slight water absorbency is used, and the tile has high durability. Become.

[0012]

As is clear from the above description, according to the present invention, the joint color of the PC board pre-tiled tile is unified, and the occurrence of efflorence and the permeation of rainwater in the joint portion are prevented, and the joint is prevented. Appearance and durability are improved. Moreover, since the surface (upper surface) of the tile is also covered with the coating film-type waterproof material, the durability of the tile is enhanced. Moreover, after the pigment is applied to the entire surface, the pigment on the surface of the tile is removed so that the pigment remains in the joints, so that the pigments can be easily and accurately applied to the joints.
