DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a tile preform for interior and exterior use in the construction field.

[0002]

2. Description of the Related Art In the field of interior / exterior materials for buildings, recently, there has been an increasing demand for high-grade materials, and tiles are often used for outer wall materials, around entrances, and outer grooves. On the other hand, the transition from wet construction using mortar to dry construction method using no mortar is progressing in order to reduce the number of tile craftsmen and simplify construction.
Further, there is an increasing demand for so-called tile leading boards, in which tiles are preliminarily set at a factory without setting tiles on site. The following manufacturing methods are known as methods for manufacturing these tile leading boards, which are different for general houses and buildings.

[0003] For general residential use, a method of attaching tiles by a tile craftsman at a factory using mortar on a cement-based extruded plate or a sheet-forming plate, or a method of attaching tiles partially by mechanization is common. is there. However, this only means that tiles are not set up on site, and the skill of craftsmen is required to adjust the tile surface and form joints, making full use of the advantages of the original tile front plate Hard to say. In addition, a method of attaching tiles in a dry manner using an inorganic or organic adhesive other than mortar on the same cement-based material as described above has been adopted, and in this case, a method of mechanically producing a tile at a factory has been attempted. However, the actual situation is that the adhesive is very expensive and cannot be manufactured at low cost as in the case of using mortar.

[0004] On the other hand, in the field of curtain walls for buildings and the like, a method of arranging tiles on a formwork and pouring concrete from above is common. For low-rise buildings, front boards are sometimes manufactured using the same method as for residential buildings.
However, in any case, the wall material itself needs to be very thick, which is not suitable for residential use.

[0005]

Due to the above-mentioned problems, there is a long-awaited need for the development of a tile-attached plate that can be easily and inexpensively produced at a factory without requiring the hands of craftsmen. That is, an object of the present invention is to provide a simple manufacturing method of a tile leading board suitably used for interior and exterior in the construction field.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
The material of the mold used in the present invention is not particularly limited, and it is preferable to use a mold having joints formed on the surface. The mold may have a planar shape or a curved shape. In the present invention, a hydraulic composition containing an ultrafine powdery substance such as granulated blast furnace slag and silica fume, a water-soluble polymer, a curing stimulant, and water is used. Specific examples of the hydraulic composition that can be used include blast furnace granulated slag described in JP-A-3-237050, ultrafine powdery substances such as silica fume, water-soluble polymers,
Hydraulic compositions containing a curing stimulant, water and the like can be mentioned. Further, as described in the above publication, a lightweight aggregate or a pigment can be used as necessary. In particular, in the present invention, the hydraulic composition is preferably colored with a pigment in order to form joints with the hydraulic composition. It is preferable that the hydraulic composition is sufficiently mixed and kneaded using a mixer, a kneader or the like.
As the hydraulic composition, a clay-like kneaded material may be used as it is, or may be used after being molded using a press or an extruder. When the hydraulic composition is used by pouring, it is preferable that the hydraulic composition has fluidity by appropriately selecting the type and molecular weight of the water-soluble polymer and the content of water.

As the inorganic material in the present invention, a hollow or solid plate material obtained by molding a cement material using general Portland cement, slag cement or the like, and curing and curing as necessary can be used. Is not particularly limited, and may be extrusion molding, press molding, or a papermaking method. In addition, as an inorganic material,
Unhardened hydraulic composition containing crushed granulated blast furnace slag described in 237050, ultrafine powdery substance such as silica fume, water-soluble polymer, hardening stimulant, etc., as it is or cured and cured as required The use of a body is preferable because the adhesion between the inorganic material and the hydraulic composition forming the adhesive layer becomes better.

It is also preferable that the surface of the inorganic material is roughened by providing irregularities, providing grooves, buffing, or the like in order to increase mechanical adhesiveness. The shape of the inorganic material is not particularly limited, and the surface may be flat or curved as long as it is a plate material, and may have a fitting portion such as a determination or a real shape for easy construction. The thickness of the inorganic material is not particularly limited.
Preferably about 100 mm, more preferably 10 mm
５０50 mm.

The tiles used in the present invention include not only general ceramic tiles for interior and exterior use, but also brick tiles, stone materials,
An inorganic artificial tile such as artificial marble or cement can be used. Further, a material obtained by processing the inorganic material used in the present invention into a tile shape can also be used. The shape of the tile is not particularly limited, and an arbitrary shape can be selected, including a commercially available mosaic tile and a two-piece tile.

Hereinafter, a method of manufacturing the tile pre-attached plate of the present invention will be described in detail for each step. Step 1 "A step of assembling the tiles using the formwork used in the present invention in consideration of the size, thickness, type, etc. of the tiles". A joint pattern is created on the formwork using metal, wood, rubber, plastic, or the like. Step 2 “Step of turning the tile upside down” The tile is placed at a predetermined position on the formwork with the surface of the tile facing down. Step 3 “Pouring or pressing a hydraulic material to form a tile joint and a tile adhesive layer” When using a hydraulic hydraulic composition, the composition is spread with a roller, Or by applying vibration to the hydraulic composition,
A layer of the hydraulic composition (tile adhesive layer) is applied uniformly on the back surface of the tile. Also, when the hydraulic composition is a clay-like kneaded material or molded product, the uncured hydraulic composition layer is provided by uniformly pressing the back surface of the tile. The amount of hydraulic composition used is adjusted according to the desired joint depth.

Step 4 "Step of pressing inorganic material". The inorganic material is placed on the tile adhesive layer uniformly provided in Step 3 and pressure is applied from above to apply the inorganic material. The pressure at this time varies depending on the hardness of the layer of the inorganic material or the hydraulic composition and the setting of the joint depth, but it is sufficient to press lightly. Thus, an integrated product of the tile, the hydraulic composition and the inorganic material can be obtained. In addition, after step 4, sand or the like may be sprinkled on the joint to give the joint a texture.

Step 5 "A step of curing and curing the integrated product of the tile, the hydraulic composition and the inorganic material prepared in the step 4" The cured product prepared in the step 4 can be cured even at room temperature. In that case, it is preferable not to dry. In addition, it is possible to shorten the curing time by heating. Curing curing usually cures in 1 to 10 hours in an atmosphere at room temperature to 90 ° C., and exhibits sufficient adhesive strength to fix the tile.
As described above, a tile leading board can be obtained.
