The length of the inorganic plate 2 is the same as or shorter than that of the concrete block 1, and the height is 10 mm or more.
The size is about 500 mm, and the thickness is about 5 mm to 50 mm. The inorganic plate material 2 is stuck with an adhesive, engaged with unevenness, fixed with screws or the like, concrete block 1
Are integrated with the concrete block 1 at the time of manufacture. 2A to 2D show examples of the integration.

The inorganic plate 2 is formed by extruding, for example, clay or the like.
Extruded, cured, and autoclaved using fired or cement, asbestos, admixtures, water, etc. as raw materials. It has high rigidity and large strength, and is economical with good workability. Further, since it is completely inorganic, it has excellent fire resistance, and is used, for example, in a tunnel, does not ignite even if a fire occurs, and does not generate harmful gas or smoke.

The decorative surface 3 of the inorganic plate material 2 is preferably of a color and high gloss excellent in discrimination according to the scenery, and glaze, inorganic paint, organic paint, etc. can be applied.
Glaze is preferred for improving weather resistance and cleaning efficiency. Glazes include, for example, lead glaze, lead-free glaze, tin glaze, porcelain glaze, majolica glaze, furnace glaze, Bristol glaze, rockingham glaze, Zegel porcelain glaze, raw glaze, clay glaze, frit glaze, volatile glaze, gloss glaze, etc. It is to be glazed on the decorative surface 3. Further, among inorganic paints, silicate paints containing anatase-type titanium oxide having excellent natural stain resistance and chemical resistance are preferred, but may be combined with organic paints according to required performance.

When the inorganic plate material 2 is bonded to the concrete block 1 with an adhesive to be integrated, cement mortar, epoxy mortar, or other synthetic resin adhesive is used as the adhesive. It is preferable that the adhesive strength is greatly promoted and that it is not deteriorated by moisture or vibration.

An example of the inorganic plate material 2 is a thin porcelain plate made of clay as a main material and fired at a temperature in the range of 1000 ° C. to 1400 ° C., and its decorative surface 3 is provided with a glaze. 60%) is 80% ~ 98%
was. 1, the decorative surface 3 of the inorganic plate 2 and the surface 11a of the concrete block 1 are flush with each other, and the end surface of the inorganic plate 2 with the surfaces 12a and 12b are flush with each other. This minimizes unnecessary irregularities,
This is to make it less soiled and easier to clean, but as a result, it has a cleaner appearance. Compared to a mere concrete block 1 in which blocks were continuously installed, it was very excellent in view of the scenery.

Next, the concrete block 1 on which the inorganic plate material 2 is formed is assumed to be installed in a tunnel on a highway.
The boundary block A was contaminated, and general brushing cleaning was performed, and the cleaning recovery power was measured. The specular gloss (60 degrees) was measured.
As shown in (3), comparing before and after washing,
Excellent mirror gloss recovery has been demonstrated.

FIGS. 4 (a) and 4 (b) show examples of installation of boundary blocks A. FIG. 4 (a) is a diagram in which permutations are formed in every other row, and FIG. It is formed. Of course, the way of installation is free.

The above embodiment only shows some examples of the boundary block A according to the present invention. For example, the inorganic plate 2 is not only fixed to one side of the concrete block 1 but also required if necessary. When the boundary block A is fixed to a plurality of surfaces, or when the boundary block A is installed, the boundary block A may be continuous or may not be continuous.

[0015]

As described above, since the boundary block according to the present invention is obtained by integrating an inorganic plate with a concrete block, the boundary block can be used as a landscape material because the inorganic plate is excellent in design. And distinctiveness (recognition)
Will be higher. Due to the application of glazes and inorganic paints, dirt does not easily adhere, and even when soiled, it has excellent cleaning recovery properties and chemical resistance. Since it has high gloss, it has a high reflectance to automobile lights and plays the role of a reflector. Since the inorganic plate material is integrated with the concrete block, the cost is reduced.
By arranging the boundary blocks in place of the concrete blocks as appropriate, it is possible to concentrate on the corners, mountains, shores, tunnels, and other parts where the recognition rate is desired to be high. There are features and effects such as.
