Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a wall material used as an exterior material in buildings and structures, and is made by extrusion molding a raw material mainly made of porcelain into a hollow shape. A hard wall material that is formed by forming an uneven pattern on the decorative surface and firing it (hereinafter simply referred to as wall material)
It is related to.

[Conventional technology]

Ceramic boards such as ALC boards have recently become quite popular as exterior wall materials. However, ALC plates and the like have disadvantages such as poor dimensional stability, high water absorption, and frequent destruction due to frost damage. In addition, ALC board is a mixture of many mixtures, such as gypsum, asbestos, perlite, pulp, cement, glass fiber, and slag, in a predetermined ratio, and it is difficult to make the mixture uniform, resulting in many variations in physical properties, and impact resistance. There was a disadvantage due to gender. Furthermore, Mizumi's ALC board has a large specific gravity and has the disadvantage of lacking heat insulation properties. For this reason, wall materials have been devised in which porcelain is used as a raw material and extruded into a hollow shape and then fired, but in this case, firing causes shrinkage, and this shrinkage affects the decorative surface. There was a drawback that the decorative surface became wavy. Moreover, since the shrinkage rate varies depending on the composition of the porcelain material, it is difficult to reproduce the wavy shape of the decorative surface.

[Purpose of the invention]

In order to eliminate these drawbacks, the present invention uses porcelain, which is a natural material, as a raw material, extrusion molds it, provides many linear hollow parts, and also has an uneven pattern on at least the decorative surface of the hollow part. The four parts are formed according to the width of the hollow part, and the four parts are placed on the partition wall of the hollow part, and the wavy appearance of the decorative surface caused by shrinkage due to firing is removed, and the reproducibility is improved. The present invention proposes a long wall material that maintains strength, heat insulation, and dimensional stability over a long period of time, and has excellent fire resistance.

〔Example〕

An embodiment of the wall material according to the present invention will be described below with reference to the drawings. Fig. 1 is a perspective view showing the above-mentioned wall material A, which is mainly made of porcelain material made of pottery stone, feldspar, clay, kaolin, etc.
This is mixed with cement, asbestos, silica, glass fibers, carbon fibers, whiskers, steel fibers, slag, and various aggregates, and then extruded into a long shape, which is then fired at a predetermined temperature. To explain further, wall material A
consists of a main body part 1 of a long plate, a hollow part 2 formed along the longitudinal direction of the main body part 1, and male and female connecting parts 6.7 formed on the left and right side walls of the main body part 1. It is something.

In particular, the main body part 1 has a large number of hollow parts 2 arranged in parallel along the longitudinal direction at the center of the plate with partition walls 3 interposed therebetween, and the decorative surface 4 is formed with a recess 5a above the partition wall 3. uneven pattern 5
was formed. This uneven pattern 5 is a pattern that has already been added when the wall material A is formed by extrusion molding, and when the wall material is fired, depressions due to the vertical shrinkage of the partition wall 3 appear on the decorative surface 4. Make sure that it is inconspicuous even if
This is to improve the reproducibility of the appearance. In addition, the raccoon convex pattern 5 has a triangular cross section, a trapezoidal shape, a repeating circular arc shape, or a convex portion 5b, as shown in FIGS.
The recessed portion 5a is formed into a trapezoidal shape, and the recessed portion 5a is formed into a triangular shape. In particular, the (kl diagram) shows an uneven pattern 5 in which the height Δh11Δh2 of the convex portion 5b is set such that Δh1 ≠Δh2.Although not shown, the uneven pattern 5 is not only a repetition of one pattern but also a combination of different patterns. The hollow portions 2 may have a square, rectangular, triangular, elliptical, etc. cross section, and are arranged parallel to each other along the longitudinal direction of the main body portion 1. This is to reduce the weight of the wall material and strengthen the heat insulation and soundproofing properties.The male type connecting part 6 and the female type connecting part 7 have a jJi female fitting structure as shown in Fig. 1, or a jJi female fitting structure (not shown). This is a part that connects wall materials A to each other, and has a mutually stacked structure or a stacked structure. 8 is a wall material attachment part, which is a part that fixes wall material A to the wall base from the back side with a mounting bracket. This is useful for avoiding damage caused by directly driving nails, etc. into the wall material A, and for preventing the nail heads from being exposed and impairing the design and waterproof properties.

Next, a construction example will be explained.

First, as shown in an enlarged view in FIG. 2, it is assumed that wall material A as shown in FIG. 1 is used for horizontal cladding. Therefore, the main pillar,
A mounting bracket β having a diagonal cross section is fixed in a predetermined position using nails T on a wall base α consisting of studs, a waterproof sheet, etc. (the waterproof sheet is omitted in the figure). Next, the wall material mounting portion 8 of the wall material A1 is fixed by falling into the mounting bracket β.

Next, the wall material attachment part 8 of the wall material At is dropped into the mounting bracket β in the same way as the wall material A+, and the female type connection part 7 of the wall material At is combined with the male type connection part 6 of the wall material A+. Fix it. The walls are formed by repeating these steps sequentially from the base to the eaves. Of course, the joints between the wall materials A can also be filled with caulking material.

What has been described above is only one example of the wall material A according to the present invention, and it is also possible to form it as shown in FIGS. . In other words, Fig. 4 (
al ~ (11 is a modification of the male and female type connecting portion 6.7,
It is formed in a mutually-jointed shape, an overlapping shape, and a whopping shape. In particular, Figure (g) shows a wall material A in which the wall material attachment portion 8 bulges downward from the main body. Note that if the shape of the mounting bracket β is such that it fixes the male connecting portion 6, it is also possible to remove the wall material mounting portion 8.

In addition, FIGS. 5(a) to (the rivers are modified examples of the decorative surface 4,

The combination of the inclined surface 4b and the inclined surface 4b can be formed into an arc shape or a triangular shape, or the decorative surface 4 can be formed in two or more stages as shown in FIGS. Figures (a) to (1), Figure 5 (in al to Fgl, uneven pattern 5

It is also possible to apply the uneven pattern 5 to an arbitrary range.

〔Effect of the invention〕

As mentioned above, the wall material according to the present invention has the characteristics that it has lower water absorption than ALC boards, is resistant to frost damage, has high dimensional stability, is lightweight, and has excellent heat insulation and sound insulation properties. Also, because the material is natural and fired at about 1200℃, the structure and shape will not change over a long period of time, and it is also possible to form a wall with a beautiful natural textured appearance. be. Furthermore, the raw materials are inexhaustible and the cost is lower than that of ALC boards. In addition, the uneven pattern substantially eliminates distortion of the decorative surface due to shrinkage of the hollow part provided in the wall material during firing, resulting in a decorative surface with reproducibility.
