Abstract

PURPOSE:To improve workability be generating split sections at positions recessed from the structural body side surfaces of engaging projected sections, when the sections split in two are formed at the engaging projected sections arranged on the upper end rear-side surfaces of square tiles, and by preventing the split sections and a structural body from coming in contact with each other. CONSTITUTION:After a pair of plate surface sections 11A, 11B provided with projected sections 16 for engaging tiles 11 with a structural body are integrally formed, a sintered body 15 is formed. Besides, in this case, sections between the projected sections 16 and the plate surfaces 11A, 11B confronted with each other are provided with split sections 12 for forming main boundary sections, recessed-channel-shaped split sections 13, and connecting sections 14 positioned on the bottom sections. After that, the sintered body 15 is separated at the split sections 12, 13, and two pieces of the tiles 11 are formed. As a result, the split sections of the connecting sections 14 are left in recessed channels and are not found on the side of the structural body, and so work can be stably executed without generating any fault, and uniform surfaces without rugged sections for executing the work can be formed.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a 2-split tile and a method for manufacturing the same, and more specifically, the split tile is formed so that the slit marks do not get in the way during dry construction of the tile. This article relates to a two-part tile and its manufacturing method.

[Prior Art] Conventionally, a dry construction method has been used in which a structure on which tiles are to be constructed is provided with a convex portion for locking the tiles, and the back surface of the tile is secured to the convex portion. In this method, for example, as shown in FIG. 5, a tile 4 having grooves 3 formed on its back surface is attached to a convex portion 2 of a frame 1 by locking it.

Incidentally, such tiles are generally made by preparing clay by mixing feldspar, pottery stone, clay, etc. in a predetermined ratio, molding the resulting clay, drying it, glazing it if necessary, and firing it. Manufactured by

As an example of a method for preparing clay, the following method is adopted. That is, after coarsely crushing raw materials such as feldspar, pottery stone and clay, they are uniformly pulverized with water in a boruru mill (wet crushing process) to form slurry. This slurry is applied to a filter press to remove water and remove wood (a), and form a clay-like cake. Next, the mixture is kneaded uniformly using a clay kneading machine to form chips (chipping process). This is thoroughly kneaded in a vacuum clay kneader while adding water to achieve uniform moisture content (kneading step) to form a homogeneous clay solid. The moisture content thus obtained is 20
Approximately 30% by weight of the clay solid material is formed into a molded body using various molding machines.

A 20% tile is widely used as the tile 4 shown in FIG. This half tile is made by extruding clay into a hollow plate shape as shown in FIG. 6, and then cutting the extruded body 5 in a direction perpendicular to the extrusion direction.

6 is a cutting line. After that, it is dried and fired, and the two parts are separated into one plate side and the other plate side as shown in Fig. 7.
Tile 4 is manufactured by dividing into pieces. and,
In order to allow the product to be split into a predetermined shape when it is divided into two, a cut 7 is made as shown in FIG. 6 during extrusion molding. This cut becomes a crack through the firing process, and 2
When splitting, it can be split into a predetermined shape along this crack.

[Problem to be solved by the invention] In the conventional method described above, when splitting along the crack, the seventh
．． As shown in Figure 8, a crack mark 8 remains on the back side of the tile 4.

Since the split marks 8 are raised higher than the surrounding surface, when the construction is performed on the building frame as shown in FIG. The back surface of the tile 4 cannot be brought into close contact with the surface of the frame 1. As a result, the tile surface may become uneven.

Although it is possible to remove such crack marks 8 with a grinder or the like, it is extremely time consuming and cannot be said to be an industrially advantageous method.

The present invention solves the above-mentioned conventional problems and provides a two-split tile and its construction method that can be constructed in close contact with the back surface of the tile and the surface of the building structure without leaving crack marks in the way during dry construction. With the goal.
