Description

The present invention relates to a method for manufacturing an external corner member . More specifically, the present invention relates to a method of manufacturing an external corner member that constitutes an external corner of a building.

Conventionally, an outer wall material is cut to form an external corner member, and a plurality of external corner members are joined to form an external corner member. For example, in Patent Document 1, when forming an external corner member by cutting an outer wall material with a large height difference between a concave portion and a convex portion and a deep handle, a narrow convex portion is formed to prevent chipping. , the width dimension of the convex portion is adjusted, and the portion other than the concave portion (joint) is cut.

By the way, when the outside corner member is cut out from the exterior wall material, the cut surface is cut so as to be inclined. Then, the inclined cut end surfaces are joined together to integrate a plurality of external corner members. In such a case, if the surface of the exterior wall material is formed with an uneven pattern and has an inclined surface that is inclined in a direction orthogonal to the cutting direction, one inclined cut end surface and the other inclined cut end surface to be joined will be different. It is difficult to match, and the tip of one of the slanted cut end faces protrudes outward from the tip of the other slanted cut end face.

If one inclined cut end face and the other inclined cut end face that are joined in this way are misaligned, the appearance of the protruding corner member may be impaired. Therefore, after joining a plurality of protruding corner members, the tip of the protruding inclined cut end surface is cut and removed.

JP 2017-179946 A

However, if the pattern depth of the uneven pattern of the exterior wall material from which the external corner member is cut is large (when the height difference of the unevenness is large), the tip of the protruding inclined cut end surface becomes large, and the area to be cut and removed becomes large. There was a problem that it took a lot of time and effort. In addition, the material inside the protruding corner member may be exposed on the protruding inclined cut end surface, and the external appearance of the protruding corner member may be deteriorated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of manufacturing an external corner member that is excellent in appearance and easy to manufacture.

In the corner material manufacturing method, a substrate having a plurality of flat convex portions and a plurality of inclined convex portions on a surface thereof is arranged in a direction perpendicular to the inclination direction of the plurality of inclined convex portions. The pair of plate-shaped external corner members are formed by cutting at a position crossing the inclined convex portions of the above- mentioned pair of plate-shaped external corner members, and the inclined cut end face of one of the pair of plate-shaped external corner members is The other of the pair of plate-shaped external corner members that has a first inclination angle with respect to the surface of the one plate- shaped external corner member and is paired with the one plate -shaped external corner member The inclined cut end surface of the external corner member has a second inclination angle with respect to the surface of the other plate-shaped external corner member, the inclined cut end surface having the first inclination angle, and the second The inclined cut end surface having two inclination angles has the same shape along the cutting direction of the base material, and the surface of the base material has a plurality of regions having the same uneven pattern in the longitudinal direction of the base material. are repeatedly formed in a direction, forming a cut portion in which an inclined cut end surface having the first inclination angle of the base material and an inclined cut end surface having the second inclination angle are formed.

DETAILED DESCRIPTION OF THE INVENTION Embodiments for carrying out the present invention will be described below.

[Outer corner material]
The external corner member 300 of the present embodiment is formed by joining a pair of external corner members 200, as shown in FIG. In this case, the inclined cut end surfaces 22 of the pair of protruding corner members 200 can be adhered together.

The tip 25a of the inclined cut end surface 22a of one external corner member 200a protrudes further than the tip 25b of the inclined cut end surface 22b of the other external corner member 200b. That is, the tip 25a of one inclined cut end surface 22a protrudes outward from the tip 26 (same position as 25b) of the joint portion between the inclined cut end surface 22a and the inclined cut end surface 22b. In this embodiment, the dimension between the tip 25a and the tip 25b is the projection dimension X, and the projection dimension X is less than 2 mm. If the projection dimension X is less than 2 mm, the tip 25a of the projecting inclined cut end surface 22a is not so large, and the time and effort required for cutting and removing it is small. In addition, the material inside the protruding corner member 200a is less likely to be exposed to the protruding inclined cut end surface 22a, and the outer appearance and waterproofness of the protruding corner member 300 are less likely to deteriorate. Since the smaller the projecting dimension X is, the better, the lower limit is 0 mm.

In the above description, the case where the inclined cut end surface 22a protrudes from the inclined cut end surface 22b has been described, but conversely, the same applies to the case where the inclined cut end surface 22b projects from the inclined cut end surface 22a.

[First embodiment]
(Base material)
The base material 100 for manufacturing the protruding corner of the present embodiment is formed of a ceramic base material, but is not particularly limited to this, and any material such as a wooden base material, a plastic base material, or a metal base material can be used. are available. The ceramic-based base material 100 is a cured product of a hydraulic material containing cement, aggregate, reinforcing fibers, and the like. When the base material 100 is a ceramic base material, the base material 100 can be formed to have a core portion and a skin portion. The core portion is the portion that forms the central portion of the substrate 100 , and the skin portion is the portion that forms the surface of the substrate 100 . Therefore, the entire surface of the core portion is covered with the skin portion. The specific gravity of the core portion is formed to be smaller than the specific gravity of the skin portion. For example, the specific gravity of the core portion can be made smaller than that of the skin portion by providing bubbles, voids, hollow holes, etc. in the core portion and not providing bubbles, voids, hollow holes, etc. in the skin portion. Therefore, the base material 100 can be formed thick without changing the weight and strength per unit area, and as a result, it is possible to form a (deep) uneven pattern with a large height difference on the surface. For example, if a 6 mm recess can be formed in a ceramic base material made of a single material, a ceramic base material having a core portion and a skin portion with the same thickness can form a recess of about 10 mm. .

As shown in FIG. 2, the base material 100 is formed in a substantially plate shape, and is formed in a substantially rectangular shape when viewed from the front (when viewed from the surface). The longitudinal direction of the substrate 100 can be the lateral direction (horizontal direction), and the lateral direction of the substrate 100 can be the longitudinal direction (vertical direction).

The surface of the base material 100 is formed as an uneven surface having a plurality of concave portions 11 and a plurality of convex portions 12 . Further, the surface of each convex portion 12 is formed with an inclined surface 15 . Although the inclination direction of each inclined surface 15 is not particularly limited, at least the inclined surface 15 inclined in the longitudinal direction of the base material 100 is included.

On the surface of the base material 100 , a constant concave/convex pattern including a plurality of concave portions 11 and a plurality of convex portions 12 is repeatedly formed in the longitudinal direction of the base material 100 . That is, the first region 16 and the second region 17 are formed in the base material 100 with the central portion in the longitudinal direction interposed therebetween. It is formed with a pattern.

(Manufacturing external corner members)
The external corner member 200 is formed by cutting out from the base material 100 . The base material 100 is cut at a plurality of cutting sites A1 to A10, thereby obtaining a plurality of external corner members 200 from one base material 100. FIG. Each of the cut portions A1 to A10 has a cutting direction perpendicular to the longitudinal direction of the base material 100. As shown in FIG. At each of the cutting sites A1 to A10, the base material 100 is cut perpendicularly to the surface and cut obliquely to the surface of the base material 100. By cutting the base material 100 obliquely, an inclined cut end surface 22 is formed. It is formed. The external corner member 200 formed in this way is plate-shaped, and each external corner member 200 has a vertical cut end surface 21 along the plate thickness direction of the external corner member 200 and the same vertical cut end surface 21 as the vertical cut end surface 21 . A slanted cut end surface 22 extending in the direction and slanted with respect to the plate thickness direction of the external corner member 200 is formed. Then, by joining the inclined cut end surfaces 22 of the pair of external corner members 200, an external corner member is manufactured.

The pair of external corner members 200 is configured by pairing a first external corner member 201 cut out from the first region 16 and a second external corner member 202 cut out from the second region 17 . The inclined cut end surface 221 of the first protruding corner member 201 is inclined at a predetermined inclination angle (first inclination angle) with respect to the surface. The inclined cut end surface 222 of the second protruding corner member 202 is inclined at a predetermined inclination angle (second inclination angle) with respect to the surface. The sum of the first tilt angle and the second tilt angle is about 90°.

As described above, the first external corner member 201 and the second external corner member 202 are formed from two different regions, the first region 16 and the second region 17, respectively. It is preferable that the first external corner member 201 and the second external corner member 202 that are paired when forming 300 have the same inclined cut end surface 221 and inclined cut end surface 222 in shape. Dimension X can be reduced. Therefore, it is preferable that the cut portions of the first external corner member 201 and the second external corner member 202 have the same shape in the cutting direction (same as the lateral direction of the substrate 100). For example, when the first external corner member 201 cut at the cutting sites A1 and A2 and the second external corner member 202 cut at the cutting sites A6 and A7 are paired, the inclined cut end face 221 is The cut portion A2 to be formed and the cut portion A6 to be formed with the inclined cut end surface 222 are formed in the same shape in the cutting direction.

Then, by joining the inclined cut end surface 221 and the inclined cut end surface 222 by gluing or the like, an external corner member 300 in which the first external corner member 201 and the second external corner member 202 are integrated is formed. can do. With this protruding corner member, the inclined cut end surface 221 and the inclined cut end surface 222 tend to have the same shape, and the projecting dimension X can be reduced.

The projection dimension X will be described with reference to FIG. 4 . As shown in FIG. 4A , the base material 30 has an uneven pattern on its surface, and includes a flat convex portion 31 with a flat surface and an inclined convex portion 33 with an inclined surface 32 . When the base material 30 is cut to form a pair of external corner members, as shown in FIG. The two cut surfaces cut by the line D are cut or cut by the slanted cutting lines E and F to form the slanted cut end surface 34 .

Then, as shown in FIG. 4C, when the two inclined cut end surfaces 34 are joined to form an external corner material, the position (cutting position) where the two inclined cutting lines E and F on the surface of the flat convex portion 31 pass. Since E1 and F1 are the same, even if the two inclined cut end surfaces 34 are joined together, no chipping (step) is formed at the tip (external corner) of the external corner material. On the other hand, the positions (cutting positions) E2 and F2 through which the two inclined cutting lines E and F pass on the inclined surface 32 of the inclined convex portion 33 are shifted in the plate thickness direction of the base material 10 . The dimension of the deviation between the position E2 and the position F2 is the projection dimension X, which appears as a chip (step) when the two inclined cut end faces 34 are joined together.

Therefore, in the present embodiment, the cut portions of the first protruding corner member 201 and the second protruding corner member 202 have the same shape in the cutting direction (same as the lateral direction of the base material 100). preferable.

[Second embodiment]
(Base material)
In the above-described first embodiment, the paired first external corner member 201 and second external corner member 202 are manufactured from one base material 100, but in the second embodiment, as shown in FIG. As shown, a first external corner member 201 and a second external corner member 202 are formed from separate substrates 101, 102, respectively. In this case, the surface shape of the substrate 101 and the surface shape of the substrate 102 are the same.

(Manufacturing external corner members)
The first base material 101 is cut at a plurality of cutting portions B1 to B10 to form a plurality of first external corner members 201. As shown in FIG. The second base material 102 is cut at a plurality of cutting sites C1 to C10 to form a plurality of second protruding corner members 201. As shown in FIG. The cutting site B1 of the first base material 101 corresponds to the cutting site C1 of the second base material 102, the cutting site B2 corresponds to the cutting site C2, the cutting site B3 corresponds to the cutting site C3, and the cutting site B4. ˜B10 also sequentially correspond to cleavage sites C4˜C10, respectively.

The inclined cut end surface 221 of the first protruding corner member 201 is inclined at a predetermined inclination angle (first inclination angle) with respect to the surface. The inclined cut end surface 222 of the second protruding corner member 202 is inclined at a predetermined inclination angle (second inclination angle) with respect to the surface. The sum of the first tilt angle and the second tilt angle is about 90°.

In this way, the first external corner member 201 and the second external corner member 202 are formed from two different base materials 101 and 102, respectively. It is preferable that the first external corner member 201 and the second external corner member 202 have the same inclined cut end surface 221 and inclined cut end surface 222 in shape, whereby the projection dimension X can be reduced. Therefore, it is preferable that the cut portions of the first external corner member 201 and the second external corner member 202 have the same shape in the cutting direction (same as the lateral direction of the substrate 100). For example, when the first external corner member 201 cut at the cutting sites B1 and B2 and the second external corner member 202 cut at the cutting sites C1 and C2 are paired, the inclined cut end face 221 is The cut portion B2 to be formed and the cut portion C2 to be formed with the inclined cut end surface 222 are formed in the same shape in the cutting direction.

Then, by joining the inclined cut end surface 221 and the inclined cut end surface 222 by gluing or the like, an external corner member 300 in which the first external corner member 201 and the second external corner member 202 are integrated is formed. can do. With this protruding corner member, the inclined cut end surface 221 and the inclined cut end surface 222 tend to have the same shape, and the projecting dimension X can be reduced.
