Description

TECHNICAL FIELD The present invention relates to an external corner structure of an outer wall of a building.

As a conventional construction of an exterior wall of a building, a technique of arranging flat ceramic siding exterior wall materials vertically and horizontally is known. In particular, in the corners of buildings, corner members that are substantially L-shaped in plan view have been used in accordance with the shape of the corners.

Japanese Patent Laid-Open No. 2002-201002 proposes a technique of forming an external corner with two flat plate-shaped outer wall materials having backing ribs formed at the side ends. As a result, both the flat portion and the protruding corner portion of the outer wall can be made of the flat plate-like outer wall material, and the manufacturing cost can be reduced compared to the case where the substantially L-shaped corner member is manufactured separately. In addition, by joining the backing shells together, a corner gap is interposed between the two outer wall materials, and damage due to interference between the outer wall materials in the event of an earthquake or the like can be prevented.

However, the structure of Patent Literature 1 is a configuration for horizontal installation, and cannot be used when it is desired to configure the outer wall to be a vertical installation.

In addition, the structure of Patent Document 1 has a structure in which the side edge of the other wall material can be seen from the front view of any of the wall materials, so the joints between the wall materials are easily visible, which impairs the design of the external corners. There is a problem that

Embodiments of the present invention will be described below, but the present invention is not limited to the following embodiments.

<First Embodiment>
As a first embodiment of the present invention, a first external corner structure 100 of a building outer wall shown in FIG. 1 will be described below.

FIG. 1 is a diagram schematically showing a first exterior corner structure 100 of a building outer wall according to this embodiment. The first protruding corner structure 100 is formed with a long-side facing shelling portion 11 in which the front side is notched on one of the long sides, and a long-side back-facing shelling portion 12 in which the back side is notched on the other long side. A rectangular plate-like outer wall panel 1 in which short side back-to-back ribs 13 are formed on both short sides of which the back side is notched, and an outer wall panel 1 for joining the two outer wall panels 1 at the outer corners of the building outer wall. A corner joiner 2 is an exterior corner structure of a building exterior wall.

2 and 3 are a perspective view and a cross-sectional view of the outer wall panel 1. FIG. More specifically, FIG. 2(a) is a front side perspective view, and FIG. 2(b) is a back side perspective view. 3(a) is a cross-sectional view across the long side, and FIG. 3(b) is a cross-sectional view across the short side.
As shown in FIG. 3, the outer wall panel 1 has a pair of long sides, one of which has a long side surface notched portion 11 with the front side notched, and the other long side with the back side notched. A backing shell 12 is formed. A pair of short sides are formed with short side back-to-back ribbing portions 13 on both sides.
The long-side back-to-back shelling portion 12 and the short-side back-to-back shelling portion 13 are different in shape of the back-to-back shelling portion, and the long-side back-to-back shelling portion 12 has a longer tongue.

At least two outer wall panels 1 in the first external corner structure 100 are composed of a short side backing portion 13 of the lateral wall panel 1 with long sides arranged in a substantially horizontal direction and a short side in a substantially vertical direction, and a short The long sides of the outer wall panels 1 are arranged substantially horizontally and the long sides are substantially vertically arranged, and the long sides of the outer wall panels 1 are butted at substantially right angles and joined together to constitute an external corner of the outer wall of the building. do.

The laterally extending outer wall panel 1 and the vertically extending outer wall panel 1 have the same shape, and the laterally extending outer wall panel 1 is rotated by 90 degrees to be used as the vertically extending outer wall panel. As shown in FIGS. 1 and 5, a plurality of exterior wall panels are repeatedly arranged vertically and horizontally on the wall surface of the building, and on the long sides thereof, there are long-side front facing shells 11 and long-side back shellings 12. The joining part 3 allows the short side backing 13 and the side end where the backing 13 is not formed on the short side, or the short side backing 13 to each other to join the planar joiners 7 and 9. is connected to another exterior wall panel 1 by

The outer wall panel 1 is used in both the external corner portion and the flat portion of the outer wall of the building, but the external wall panel 1 used for the external corner portion at the construction site is usually used after being cut to size. This is because the dimensions of the outer wall panels 1 shipped from the factory are standardized, and it is difficult to match the dimensions of the actual outer wall of the building by simply arranging them. Since the cut end of the cut outer wall panel 1 has a substantially flat shape, the joint with another outer wall panel 1 is processed at the site to form the short side backing bark portion 13 or adapt to the flat end. It is preferable to perform the joining using a planar joiner 7 that has been designed.

The joining parts 3 and the planar joiners 7 and 9 are fixed with screws 4 to the pillars 51 and the furring strips 6 of the internal structure of the building. In this embodiment, the planar joiner 7 joins the short-side back shell portions 13 of the two outer wall panels 1 and the side edges where the short-side back shell portions are not formed, and the planar joiner 9 joins the short-side back shell portions. It is used to join 13 together. When the outer wall panels 1 are repeatedly arranged in the horizontal direction, the pillars 51 of the building often do not correspond to the locations where the joining parts 3 are to be arranged, especially on the wall surfaces that are vertically installed. Therefore, when installing the outer wall panel 1, it is preferable to provide a horizontal furring strip 61 as a base for fixing the joining parts 3 as required both vertically and horizontally.

FIG. 4 is a perspective view showing part of the first protruding corner structure 100 of this embodiment.
In the external corner, the short-side backing burrs 13 of the laterally stretched outer wall panel 1 and the long-side backing burrs 12 of the vertically stretched outer wall panel 1 are butted at substantially right angles to form the outer wall of the building. An external corner is configured. In the present embodiment, the long side backing 12 of the vertical outer wall panel 1 is the winning side, and the short side backing 13 of the horizontal outer wall panel 1 is the losing side. As a result, since the tongues of the long side backing burrs 12 of the vertical exterior wall panel 1 are formed long, the horizontal exterior wall panel 1 is formed by the tongue when viewed from the front of the vertical exterior wall panel 1. Covered and invisible. That is, the joint of the outer wall panel 1 is not exposed at the external corner, and the design of the exterior of the building is improved.

In addition, since the outer wall panel 1 is formed with the short side backing ribs 13 on both short sides, the external corner structure 100 can be formed regardless of which side comes to the external corner. The handling of the panel 1 is facilitated, and the workability of the wall mounting construction is improved. Specifically, when the short side backing hole portion 13 is not formed on one of the short sides, the end of the short side is the short side backing hole portion 13 formed on the lower side of another outer wall panel 1. Since the first external corner structure 100 cannot be constructed on the losing side, it is necessary to handle the outer wall panel 1 in consideration of the side on which the short side backing ribbing portion 13 is constructed.

According to the first protruding corner structure 100 of the present embodiment, in the outer wall of the building, one type of outer wall panel 1 can exhibit different design properties depending on the direction of the wall surface. For example, by making the front and back sides of the building vertical and the side walls of the building horizontally, the front and back sides of the building have a vertical design and the side walls have a horizontal design with one type of exterior wall panel 1. can be configured to

A gap 24 is formed between the two outer wall panels by the back surface of the long side backing shell 12 of one of the outer wall panels 1 and the notch portion of the matching shell 13 of the other outer wall panel 1. be. In addition to inserting the vertical side portion 21 of the external corner joiner 2 described later in this gap 24, it has the effect of absorbing the shock when the outer wall receives external force such as when an earthquake occurs, and preventing damage to the side end portion. .

The outside corner joiner 2 is a component for joining the two outer wall panels 1 with the short-side backing shell part 13 and the long-side backing shell part 12, and extends vertically along the pillar 51, and the spacer 23. It is attached to the pillar 51 of the building by the screw 4 through. The vertical insert is inserted between the short side backing shell 13 formed on the short side of the laterally stretched outer wall panel 1 and the long side backing shell 12 formed on the lower side of the vertically stretched outer wall panel 1. It is configured to have a side portion 21 and is arranged on the interior side of both the outer wall panels 1 . A sealing material 22 is arranged between the external corner joiner 2 and both outer wall panels 1 to prevent rainwater from entering from the joints of the external corners.

The external corner joiner 2 is a metal part that extends vertically and is configured in a substantially L shape in a plan view, and has a vertical side portion 21 on the outer side of the corner portion of the L shape as shown in FIG. 1 . As described above, the vertical side portion 21 is inserted and fixed between the back-to-back shell portions of the two outer wall panels 1 forming the external corner, thereby forming the first external corner structure 100 . In addition, both ends of the L-shape protrude so as to be folded back outward, and when these protruding portions are brought into contact with the interior side surface of the exterior wall panel 1, rainwater, etc., entering from the joints of the external corners is prevented from flowing into the wall surface. It is possible to prevent deep intrusion.

Next, a procedure for configuring the first external corner structure 100 of this embodiment will be described.

FIG. 5 is a diagram for explaining the procedure for configuring the first protruding corner structure 100 of this embodiment.
First, as shown in FIG. 5A, the furring strip 6 is attached to the internal structure 5 including the pillar 51 . As described above, by attaching the horizontal furring strips 61 to the surfaces to be vertically stretched, the joining parts 3 can be fixed and the exterior wall panels 1 can be arranged side by side.

Next, as shown in FIG. 5B, an outside corner joiner 2 is attached to the outside corner. Also, a starter member 62 for stably attaching the panel is attached to the lower side of the external corner where attachment of the outer wall panel 1 is started.

Subsequently, as shown in FIG. 5C , external corners are formed by attaching the first outer wall panels 1 on each side vertically and horizontally along the starter member 62 .

Finally, as shown in FIG. 5D , a plurality of outer wall panels 1 are joined and attached in order from the first outer wall panel 1 . Thereby, the first protruding corner structure 100 of the present embodiment is completed.

The first external corner structure 100, which is the first embodiment of the present invention, has been described above. According to the first external corner structure 100, in the external corner structure of the building outer wall composed of two flat plate-shaped outer wall materials, it is possible to construct a vertical structure, and the outer wall panel 1 on the winning side is 2 in front view. The joints between the two outer wall panels 1 are not visually recognized, and the design of the building appearance is improved. Furthermore, one type of exterior wall panel 1 can exhibit different design properties depending on the direction of the wall surface.

<Second embodiment>
