DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner member attached to a corner of an outer wall of a building and a corner structure using the same.

[0002]

2. Description of the Related Art As shown in FIG. 12, an elongated corner formed at the outer corner of an outer wall of a building is generally formed so that left and right outer corner constituent members abut each other at an angle of about 90 degrees. Column A is used. Usually, at the time of manufacture, as shown in FIG. 13A, at the manufacturing plant of the exterior material, as shown in FIG. The tapered cut portions 2 and 2 are cut into the tapered cut portions 2 and 2 (FIG. 13B), and the tapered cut portions 2 are bonded together and, if necessary, tacked 7 (FIG. 1).
3c), the angle is unified (FIG. 13d). In addition, if necessary, the abutted ridge portion may be formed into a flat chamfered portion 5 (FIG. 13).
e).

[0003] Considering the exterior design of various buildings, it may be preferable that the angle of the protruding corner is not 90 degrees but an obtuse angle or an acute angle. In such a case, the butting angle of the left and right corner forming members is not 90 degrees, but an obtuse angle or an acute angle is required. At that time, the manufacturing method is almost the same as that described above, and the cutting angle of the tapered cut portion 2 formed on one long side of the protruding corner component cut out to a required width is adjusted and fixed integrally. By dealing with it.

[0004]

The angle of the protruding corner in a general building is approximately 90 degrees, and a large number of protruding corner members forming approximately 90 degrees as shown in FIG. There is not much inconvenience in producing. But,
In the case of an obtuse angle or an acute angle, there is an optimal angle for each building,
Accordingly, it is necessary to prepare various kinds of corner members having various different angles, and the required number of individual corner members is not large. For this reason, the production format at the factory must be exactly the form of multi-product small-lot production. As described above, a tapered cut section is formed on one long side of the protruding corner component cut out to the required width as described above. The manufacturing method of forming and integrally bonding together causes high production costs.

[0005] If a building is designed so that the angle can be limited to several types and a corner member is manufactured at a factory in accordance with the design, cost improvement can be suppressed to some extent, but a corner angle of 90% can be suppressed. It is not easy to assemble corners of a building that forms an obtuse angle or an acute angle than in the case of degrees, and often involves an assembling error. In such a case, it is very difficult to cope with the situation at the site by using a corner member integrated in an angle-invariable state.

Further, as described above, the corner member formed by integrally bonding the left and right corner members at a predetermined angle may cause cracks or chipping at the joint portion, and some products may be formed. It is necessary to consider the yield. In addition, the angled corner member must be transported from the manufacturing factory to the construction site in a different form from the flat exterior material, which becomes complicated and causes cracks and chips during transportation. Cheap. The present invention has been made in view of such a situation, and an object of the present invention is to provide a protruding corner member that can be easily constructed at an arbitrary angle at a construction site. Another object of the present invention is to provide a protruding corner member which is free from cracking and chipping at a corner portion and is easy to carry.

[0007]

According to the present invention, there is provided a corner member in which at least two corner members are joined by a flexible member on the back side thereof. And The two or more protruding corner components may be cut out from the exterior material at a predetermined width, similarly to the conventional protruding corner members,
Alternatively, it may be manufactured for that purpose. The flexible member is optional, provided that two or more corner components are not easily separated from each other, but may be a steel plate (iron, stainless steel, aluminum), a flame-resistant plastic material or rubber. Materials and the like are preferable, and particularly, steel plates are preferable because they have elasticity and high weather resistance.
When three or more corner components are joined, only one less flexible member is used than the number of the corner members, and the other corner members except for the corner members located at the left and right ends are used. The corner component is joined at its both longitudinal ends by the flexible member.

The corner member according to the present invention has the above-mentioned structure, and the angle formed by two or more corner members is arbitrarily changed, that is, not only 90 degrees but also an obtuse angle or an acute angle. Can be. Therefore, it is possible to cope with all of the optimum corner angles according to individual buildings only by producing one kind of corner member at a factory, and the construction cost at the corner portion is reduced. In addition, the two or more protruding corner constituent members are joined by a flexible member on the back surface side, so that the occurrence of cracks and chips at the corners is greatly reduced.

In a preferred embodiment, the corner member according to the present invention comprises two or more corner constituent members when not in use.
It can be opened by 80 degrees and can be bent to a required angle when used. In this aspect, the transportation from the manufacturing factory to the construction site can be performed in the same form as the flat-shaped exterior material, and the transportation can be simplified.

In a preferred embodiment, the corner member according to the present invention is such that two or more corner members are joined to the flexible member at a predetermined interval, thereby forming a part of the flexible member. Is exposed on the surface side. By doing so, there is an advantage that the degree of freedom of bending of two or more corner forming members can be increased. The present invention also provides
A corner structure of a building to which the above corner member is attached is also disclosed. In this protruding corner structure, a second protruding corner member, an auxiliary member such as another decorative member or a caulking material is used in order to improve the appearance design and strength in the corner portion and to improve waterproofness. Mounting is a preferred embodiment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on preferred embodiments. FIG. 1 is a perspective view of one embodiment of a protruding corner member according to the present invention as viewed from the back side, and FIG. 2 is a view of the embodiment from above, illustrating a state in which the angle is adjusted. . The come-out corner member 10 is composed of two pieces, that is, left and right come-out constituent members 11a and 11b, and a flexible member 15 that joins them on the back surface side. In this example, the left and right corner forming members 11a and 11b are cut out from the exterior material at a predetermined width in the same manner as described with reference to FIGS. 13a and 13b. To form tapered cut portions 12a and 12b.

The flexible member 15 is made of a steel plate in this example, and has a length substantially the same as that of the protruding corner constituent members 11a and 11b. The overall shape is a shape obtained by bending the central portion of the flat plate upward and convexly, and a left horizontal portion 16a adhesively bonded to the back surface of the left corner forming material 11a, and bent upward from the left horizontal portion 16a to form a left corner forming portion. A left upright portion 17a adhesively bonded to the tapered cut portion 12a of the material 11a, a flat central portion 18 extending horizontally from the tip thereof, and bent downward therefrom to the tapered cut portion 12b of the right corner forming material 11b. It comprises a right upright portion 17b to be adhesively bonded and a right horizontal portion 16b extending horizontally from the lower end thereof and being adhesively bonded to the back surface of the right corner forming material 11b.

The tapered cut portions 12a, 12b
And the central part 1 of the flexible member 15
The width of 8 may be appropriately selected in consideration of the extent to which the corner member 10 is to be bent at the construction site and executed so as to allow the bending. In this example, as shown in FIGS.
From a), an open state at an obtuse angle (FIG. 2b),
The cut angle and the width of the central portion 18 are designed so that the ridge lines on the back side almost contact each other at the time of 90 degrees. You have set. By setting in this way, the corner processing at the site becomes easy.

FIGS. 3A and 3B show a modified example of the corner member 10 shown in FIGS. As shown in FIG. 1, in the above example, after the construction, the flat central portion 18 of the flexible member 15 is exposed to the outside, and the protruding corner portion becomes a flat surface. 3a and 3b are intended to enhance the design by covering the part with an appropriate auxiliary member, and the corner member 10a of FIG. 3a is made of a material such as a rubber material or a plastic material. An auxiliary member 20a whose ridge portion has an angle of about 90 degrees is attached over the entire length of the central portion 18. As shown in FIG.
In the case of Oa, since the central portion 18 of the flexible member 15 is not exposed to the outside when bent and constructed, and the corner is at 90 degrees, an improvement in the appearance design can be expected. FIG. 3b
Is different from the corner member 10a in that the cross-sectional shape of the auxiliary member 20b is semicircular. The auxiliary members 20a and 20b may be bonded and joined at a manufacturing factory, or may be bonded and joined at a construction site before or after construction.

FIG. 4 shows still another form of a corner member.
In the corner member 10c, the central portion 18a of the flexible member 15 is not a flat surface but a surface curved concavely toward the rear surface. This concave curve is formed by bending the auxiliary member 2 such as a caulking material in a state where it is bent at an appropriate angle as shown in the figure.
It can be effectively used for placing 0c.

FIGS. 5A and 5B show still another form of a corner member. The corner members 10d and 10d 'are flexible members 1a and 1b.
5 is that the right upright portion 17b is directly connected to the tip of the left upright portion 17a without having the central portion 18.
The configuration is different from that of the above-mentioned corner member. Since the flexible member 15 of this embodiment does not have the central portion 18, the bending angles of the left and right corner forming members 11a and 11b are limited. That is, the corner member 10d shown in FIG. 5A and the corner member 1 shown in FIG.
As can be seen from a comparison with 0d ', in order to bend at a large angle, the cut angles of the tapered cut portions 12a and 12b must be reduced, and as a result, the width of the tapered cut portions 12a and 12b becomes wide. And the strength of that portion may be reduced. However, in this embodiment, as shown in the figure, the entire outer surface is covered with the corner forming members 11a and 11b, and the flexible member 15 is not exposed to the outside (if any, the ridge line portion of the flexible member 15). Only), there is an advantage that post-coating after the application can be performed with a minimum width.

FIG. 6 shows still another form of the corner member.
In this protruding corner member 10e, the flexible member 15 is made of a material such as an aluminum steel plate or a plastic material. The overall shape of the flexible member 15 is substantially planar, and is adhesively bonded to the rear surface of the left horizontal portion 16a and the rear surface of the right outer corner component 11b, which are adhesively bonded to the rear surface of the left outer corner component 11a. Right horizontal portion 16b, left horizontal portion 16a and right horizontal portion 1
6b, and a central portion 18b connecting the central portion 18b and the tapered cut portions 12a and 12b of the corner forming members 11a and 11b. A void 22 is formed at the bottom.

In this protruding corner member 10e, as shown in FIG. 6, the central portion 18b of the flexible member 15 enters the space 22 at the time of bending, so that the tapered cut portions 12a,
There is an advantage that a large bending angle can be obtained without making the cut angle of 12b so small. However, there is a gap at the corner where the left and right corner components 11a and 11b abut,
There is a danger of rainwater seeping in from there. In order to avoid this, as shown in the figure, the left and right corner constituent members 11a, 11b
It is recommended to attach the second protruding corner member 30 to the corner where the abutment comes into contact.

FIG. 7 shows still another form of the corner member.
In the corner member 10f, two left and right corner constituent members 11 are provided.
In addition to a and 11b, another centered corner forming member 11c (having long sides on both sides thereof as tapered cut portions 12c and 12c cut at a predetermined angle) is disposed at the center. The flexible members 15 having the shape shown in FIG. 5A are respectively arranged between the protruding corner components 11a, 11c, and 11b, and the three protruding corner components 11a, 11c, and 11b are integrally connected and joined. In this respect, the configuration is different from the above-described corner members.

FIG. 8 shows still another form of the corner member.
In this corner member 10g, left and right horizontal portions 16a, 16b of the flexible member 15 are provided on the back surfaces of the corner members 11a, 11b.
1 and 2 in that the stepped portions 13a and 13b are formed to accommodate the corners.
The steps 13a and 13b can be formed on any of the other corner members 10a to 10f described above. With this shape, the entire back surface of the corner member 10g can be made a flat surface, so that there is an advantage that the surface of the corner member 10g is not damaged when transported in an overlapping manner.

Next, an extruded corner structure using the above extruded corner member and a method of constructing the same will be described with reference to an example in which the extruded corner member 10 shown in FIGS. 1 and 2 is used. As shown in FIG. 2A, the protruding corner member 10 is packed at a factory in a state where it is opened at 180 degrees and carried into a construction site. At the construction site, it is fastened to the protruding corner in a state where it is bent according to the angle of the protruding corner to be constructed. In the example of FIG.
In contrast, the corner member 10 is fixed in a state of being bent at 90 degrees. In the figure, reference numeral 1 denotes an exterior material, and a hat joiner 53 is attached between the side edges of the left and right corner material 11a, 11b of the edge member 10 and the side edge of the exterior material 1. Is filled with a sealing material 54.

FIGS. 10a and 10b show another example of attachment. In FIG. 10a, two columns 50a and 50b are erected at an obtuse angle α, and are struck against the two columns 50a and 50b. The same corner member 10 as that used in FIG. 9 is fixed to the frame members 51 and 51 by screws 52 and 52 while being bent at an angle α. Even if the angle α is an arbitrary angle, attachment is possible, and it is easy to absorb an assembly error on the skeleton side. FIG. 10B is an example in which the same corner member 10 is retrofitted to an existing wall portion 60 bent at an angle β, and an appropriate body member 51 is attached to the surface of the existing wall portion 60. By hitting, mounting work becomes possible regardless of the angle β.

FIG. 11 shows a further example of the construction of a protruding corner portion. In this case, the three protruding corner constituent members 11a shown in FIG.
A projecting corner member 10f having 11c and 11b is struck to a projecting corner portion forming substantially 90 degrees to construct a projecting corner structure. As shown in the figure, the left and right corner forming members 11a, 11b are struck by screws 52 at a crossing angle of substantially 90 degrees with the body edge members 51, 51 attached to the column 50, and the center corner member is formed. 11c constitutes a corner portion forming an angle of approximately 45 degrees with respect to it. The angle formed by the central corner member 11c is arbitrarily changed by changing the mounting position of the left and right corner composing members 11a, 11b with respect to the rim members 51, 51.
This example shows that even when the skeleton side has a 90-degree corner, a corner pillar having a wide chamfer inclined at an arbitrary angle can be easily formed there. A corner structure is obtained.

[0024]

According to the corner member according to the present invention, a corner structure having an arbitrary corner angle can be easily constructed at a construction site. Therefore, workability is improved, and appearance design is also improved. In addition, since it can be opened in a flat shape, it is possible to perform packing in the same manner as in the case of a flat exterior material, and transport becomes easy.
