Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an architectural exterior wall board for horizontal installation, in which colored stainless steel or colored titanium plates are used as the surface material, and the embossing on the surface is made to look like an acute angle (step). It is processed so that it appears to be 0.8 mm or more), making it highly durable and luxurious in design.

<Conventional technology> Architectural exterior wall panels made of thin metal sheets are easier to construct and take less time than the wet mortar conventionally used for the exterior walls of single-family homes, and are suitable for use in cold regions because they do not have cracks and are free from frost damage. It is widely used mainly in

Examples of conventional external wall boards for construction include those disclosed in Japanese Patent Publication No. 51-29339, Japanese Utility Model Publication No. 51-11882, Japanese Utility Model Publication No. 54-26649, and Japanese Unexamined Patent Application Publication No. 1983-61-64.
There are those shown in Japanese Patent No. 953 and Japanese Utility Model Application No. 61-113835.

<Problems to be solved by the invention> However, since conventional products like this mainly use colored zinc iron plates as the surface material, iron powder that is generated during cutting on site and is generated from the cut surface is a problem. They have the disadvantages of rust and short service life in environments where sea salt particles are scattered near the coast. In addition, the surface embossing was not very accurate and the carvings were shallow, so it was not useful for improving bending strength, and compared to sprayed material applied on site, only a flat pattern was obtained.

In addition, although the connecting parts between the panels have been made using engineering technology, they are insufficiently waterproof, and moreover, the connecting parts tend to twist easily, resulting in problems with the strength and waterproofness of the connecting parts.

Furthermore, urethane foam or isocyanurate foam is used on the back of the panel for insulation purposes, but these have the disadvantage of being flammable and emitting a large amount of smoke, and the embossed T on the surface material is shallow. Because of this, the adhesion between the surface material and the lining material (insulation material) is weak.
It had the disadvantage of being easy to peel off.

In other words, in order to eliminate these conventional drawbacks, it is necessary to use materials that do not rust even when cut at the T installation site, and to create completely waterproof materials. The structure of the connecting part is such that the embossed part has a deep and clear pattern with large steps, which increases the adhesion with the backing material and makes it look luxurious.Moreover, the backing material has excellent fire retardant properties. materials must be used.

Therefore, the architectural exterior wall board according to the present invention has a backing material between the surface material and the back material, and a female type connecting part is formed on the lower edge and a male type connecting part is formed on the edge. For horizontal architectural exterior wall panels, the surface material is a stainless steel plate or titanium plate with double-sided embossing with a step difference of 0.8 mm or more, and the lower edge of the surface material is bent so that the front side is approximately half the thickness. Stretch it upward, then bend it downward to make the back side an insertion groove, extend the lower end to the same length as the insertion groove to form an insertion part, to form a female connecting part, and the upper edge After making the surface material with a sloped surface to a thickness that matches the position of the insertion groove of the female type connecting part, stretch it a little longer than the length of the insertion groove of the female type connecting part, and bend it to match the thickness of the insertion groove. Stretch it downward to form an insertion part, extend it to a length that matches the insertion part of the female type connecting part, bend it to form an insertion groove, and then extend it to a position above the insertion part to form an extension part. The upper end of the extending part is bent to the back side to form a mounting wood-blocking part to form a male type connecting part, and the extending part of the male type connecting part is bent to the front side in a chevron shape or (and) a female type. By bending the insertion part of the connection part into a chevron shape to the back side to form a waterproof rib, and using a colored stainless steel plate or colored titanium plate with embossed finish on both sides for the surface material, rust is prevented and the carving is deep and luxurious. At the same time, the adhesive strength with the backing material has been increased, waterproof ribs have been formed on the joints to prevent water from entering through the joints, and phenol foam has excellent heat insulation and fire retardant properties. be.

Embodiment Example Next, an embodiment of the architectural exterior wall board according to the present invention will be described based on the drawings. 1 is a surface material, 2 is a back material, and 3 is a backing material filled in between. be. A female connecting part 4 is formed on the lower edge, and a male connecting part 5 is formed on the upper edge.The surface material 1 is made of a thin plate of colored stainless steel with embossing on both sides, resulting in a step difference of 0.8 mm. It is formed from the above. Furthermore, if the surface material 1 is a titanium plate, the anti-corrosion properties will be further improved, and the weight will be significantly reduced compared to a stainless steel plate.

The back material 2 is nonflammable, waterproof, heat insulating, sound insulating, and has the function of fixing the backing material (insulating material) 3, and is made of, for example, asbestos paper, kraft paper, asphalt felt, gold [j (A Pb, Fe, Cu), synthetic resin sheets, rubber sheets, cloth sheets, glass cloth, gypsum paper, aluminum hydroxide paper, calcium silicate paper, etc. are used. The backing material 3 uses phenol foam which has excellent fire retardant properties.

The female connecting part 4 at the f edge is formed by bending the surface material l as follows. The lower end of the surface material 1 is bent to about half the thickness, stretched upward, and then bent downward to form an insertion groove 6 on the back side. Then, this is further extended to the lower end to have the same length as the insertion groove to form the insertion part 7. The lower end is bent to the back side for waterproofing and to prevent twisting.

The male connecting portion 5 at the upper edge is formed by bending the surface material 1 as follows. The thickness of the surface material 1 is such that the inclined surface 8 matches the position of the insertion groove 6 of the female connecting portion 4. Then, it is extended a little longer than the length of the insertion groove 6 of the female connecting part 4, bent to match the thickness of the insertion groove, and extended downward to form the insertion part 9. Then, the insertion groove 10 is formed by stretching the female connecting part 4 to a length corresponding to the insertion part 7 and then bending it. Furthermore, the extending part 11 is extended so as to be at a position above the insertion part 9.
Then, the upper end of the extending part is bent to the back side to form the attachment waterproof part 12.

In addition, the extending portion 11 of the male connecting portion 5 is provided with a waterproof rib 13 bent toward the front side in a chevron shape. Further, as shown in FIG. 4, the waterproof rib 13 may be formed by bending the insertion portion 7 of the female connecting portion 4 into a chevron shape toward the back side. In addition, depending on the case, Fig. 6.

As shown in FIG. 7, a plurality of waterproof ribs 13 may be formed.

The decorative surface 14 on the front side of the surface material l has a decorative material i as shown in the figure.
IV! 15 or a decorative inclined surface 16 may be formed.

Here, a method for performing double-sided embossing on a colored stainless steel plate with deep carvings, that is, with a step difference of 0.8 mm or more, which was previously considered impossible, will be described. In the traditional method,
Even if double-sided embossing is performed, only steps up to a maximum of 0.6 mm can be embossed. In order to perform double-sided embossing with a step difference of 0.8 mm or more, a film original with a design that has been repeatedly modified so that the upper and lower rolls interlock is produced.
Etching allows for deep carving up to 1.5mm. Re-quenching is performed after etching, which extends the life of the roll and enables deep embossing.

By embossing on both sides using a deep-carved roll like the one used by Kokita, it has become possible to create clear patterns on colored stainless steel material by embossing both sides with a deep step of 0.8 mm or more.

In addition, the deep carving increases the unevenness, which strengthens the bond between the panels and makes them difficult to separate, and improves the adhesion of the phenol foam. Embossing also has the effect of improving bending strength.

Kusaku Kawa> However, as shown in Figure 3, the lower exterior wall board was installed with the waterproof part 12 facing upward, and the extension part 11 was attached to the mounting surface 18 of the column 9 stud, +7 base, old edge, etc. Fix it with nails 17 or the like. Then, the insertion part 7 of the upper outer wall board is inserted into the insertion groove 1O of the lower outer wall board, and the insertion part 9 of the upper outer wall board is inserted into the insertion groove 6 of the lower outer wall board, and the connections are made by dropping. At this time, the waterproof rib 13 has the effect of fixing the insertion part 7 more strongly and improving the waterproof performance at the same time. As a result, rainwater does not reach the back surface and corrode the pillars and wall materials.

<Effects of the Invention> As described above, according to the architectural exterior wall board according to the present invention, durability is improved because a stainless steel plate is used as the surface material, and a luxurious design is achieved due to the deep embossing on both sides. In addition, the adhesion between the surface material and the backing material can be strengthened, and the waterproofness of the joint can be improved by forming waterproof ribs on the joint. The effects of this, such as improved fire protection, are extremely large.
