Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a connecting portion of an exterior material made of ceramic material.

[Background Art] As shown in FIG. 6, the conventional ceramic exterior material A' has a fitting convex portion 3 at one end of one ceramic exterior material A', and the other end of the ceramic exterior material A' fits into the fitting protrusion 3 at one end of the ceramic exterior material A'. A joint notch 4' that is connected by fitting the mating recess 2 and is continuous with the outer surface of the mating protrusion 3 in front of the outer surface of the mating protrusion 3.
A connecting joint is formed between the fitting recess 2 and the end surface of the outer piece 2a of the fitting recess 2. However, in such a conventional example, if the depth D of the joint notch 4' is shallow, the thickness T of the outer piece 2a of the fitting recess 2 becomes thin, and the ceramic exterior material A' is likely to crack or chip when handled. There was a drawback. For this reason, it is possible to increase the depth D of the joint notch 4' and increase the thickness T of the outer piece 2a of the fitting recess 2, as shown in FIG. There was a drawback that the depth of the connection joint formed in the notch 4' was deeper than the decorative joint 5 in other parts, resulting in a disharmonious appearance.

[Purpose of the invention] The present invention has been made in view of the above points, and the purpose of the present invention is to form a joint notch while making the outer piece of the fitting recess sufficiently thick. To provide a ceramic exterior material that can harmonize the appearance by making the depth of the connecting joints substantially the same as the decorative joints.

[Disclosure of the invention] The ceramic exterior material of the present invention has a fitting recess 2 at one end of the exterior material body 1 and a fitting convex portion 3 that can fit into the fitting recess 2 at the other end of the exterior material body 1. In the case where a decorative joint 5 is provided on the outer surface of the exterior material body 1 and a joint notch 4 is provided on the outer surface side in front of the fitting convex portion 3, the outer surface of the fitting convex portion 3 and the joint notch 4 are provided. A stepped portion 6 in which the bottom surface of the joint notch 4 protrudes outward is provided between the joint notch 4 and the decorative joint 5.
The depth is approximately the same as that of the conventional example, and the drawbacks of the conventional example are solved by configuring it as described above. In other words, a stepped portion 6 in which the bottom surface of the joint notch 4 protrudes outward is provided between the outer surface of the fitting convex portion 3 and the joint notch 4, and the depth between the joint notch 4 and the decorative joint 5 is increased. By making them approximately the same, even if the thickness of the outer piece 2a of the fitting recess 2 is made sufficient, the depth D to the bottom of the joint notch 4 can be made approximately the same as the depth d of the decorative joint 5, which improves the appearance. It has become possible to achieve harmony.

The present invention will be explained in detail below with reference to Examples.

Ceramic exterior material A is made by extrusion molding ceramic materials such as asbestos cement.
It is formed as shown in . A fitting recess 2 is formed at one end in the left-right direction of the main body 1 of the ceramic case A, and a fitting convex portion 3 that fits into the fitting recess 2 is provided at the other end in the left-right direction. It is installed protrudingly. Decorative joints 5 are perforated vertically and horizontally on the outer surface side of the exterior material body 1, and a pattern is formed on the outer surface side. A plurality of vertical ventilation grooves 7 extending in the vertical direction and a plurality of horizontal ventilation grooves 8 extending in the horizontal direction are bored on the inner surface side of the exterior material main body 1. A joint notch 4 is recessed in front of the outer surface of the fitting convex portion 3. The depth D to the bottom of the joint notch 4 is approximately the same as the depth d of the decorative joint 5, so that the bottom of the joint notch 4 protrudes outward from the outer surface of the fitting projection 3. Step 6
is provided. By providing the stepped portion 6 and making the joint notch 4 shallow in this way, the thickness T of the outer piece 2a of the fitting recess 2 can be made sufficiently thick. Further, a locking groove 9 is provided on the inner surface side of the fitting convex portion 3. The fixing fitting 10 has a fixing piece 10a, a first locking piece 10b, and a second locking piece 10a.
The locking piece 10c is formed as shown in FIG. Therefore, as shown in FIG. 1, a plurality of ceramic-based exterior materials A are arranged side by side on the outer surface side of the outer wall main body 11, and the ceramic-based exterior materials A that are adjacent to each other on the left and right are connected to the fitting protrusion 3 and the fitting recess 2. The fixing piece 10a of the fixing bracket 10 is connected to the outer wall body 1 with the fixing nail 12.
1, the first locking piece 10b is locked between the fitting protrusion 3 and the fitting recess 2, and the second locking piece 10c is locked and fixed in the locking groove 9. . When the ceramic exterior materials A are constructed in this way, the connecting joints and decorative joints 5 formed by the end faces of the outer pieces 2a of the fitting recesses 2 and the joint notches 4 are formed between the adjacent ceramic exterior materials A. The depth d will be the same.

FIG. 4 shows another embodiment similar to the above, in which the bottom of the decorative joint 5 has a two-step shape, and a two-step stepped portion 6 is provided at the bottom of the joint notch 4 to match the shape of the decorative joint 5. is provided.

Furthermore, FIG. 5 shows another embodiment described above. In the case of this embodiment, the ceramic exterior material A is provided with a fitting convex portion 3 by notching the outer surface side of the exterior material main body 1.
A fitting recess 2 is provided by cutting out the inner surface of the holder.
Also at this time, the stepped portion 6 is provided so that the depth to the bottom of the joint notch 4 and the depth d of the decorative joint 5 are the same. This ceramic exterior material A is the exterior wall body 11
The fitting convex portion 3 is connected to the fitting concave portion 2 by fitting into the fitting convex portion 3 and the fitting concave portion 2, and is directly fixed with a fixing nail 12.

[Effects of the invention] As described above, the ceramic exterior material of the present invention has a stepped portion between the outer surface of the fitting convex portion and the joint notch so that the bottom surface of the joint notch protrudes outward. Since the depth of the notch and the decorative joint are approximately the same, even if the outer piece of the fitting recess is made thick enough, the depth to the bottom of the joint notch will be reduced by the step. The depth can be made approximately the same as the joint depth, and it ensures sufficient strength to prevent the outer piece of the fitting recess from cracking or chipping, while ensuring a harmonious appearance when connected with ceramic exterior materials. It is something that can be harvested.
