Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an inside corner joining member for an exterior decorative laminate that can extremely orderly join substantially right-angled inside corners of an exterior decorative laminate.

[Conventional technology and its problems]

Conventionally, when a general residential building has a folded plate roof with a low peak height, the outer periphery of the folded plate roof has been designed to be decorated and at the same time to provide rain protection (watertightness). Therefore, an exterior decorative board with an appropriate cross-sectional shape is provided.

When viewed from above, the exterior decorative board has a configuration in which appropriate cross-sections are formed linearly in the longitudinal direction and are connected at corners, as shown in FIG. Even when the exterior decorative board is composed of a vertical surface and an inclined surface, as shown in FIGS. It was formed at a right angle. this is,
It was simply a base material with an L-shaped cross section bent at an appropriate angle.

Therefore, when joining at the inside corner of the exterior decorative board, when viewed from the ridgeline direction, as shown in FIG. Even if a piece is forcibly fixed with rivets, etc., distortion will occur near the edges of both slopes of the exterior decorative board adjacent to the corner, which will not only damage the appearance, but also expose the edges of the slope and cause corrosion. There was a flaw that caused this.

[Means to solve the problem]

Therefore, the inventor worked diligently to solve the above problem.
As a result of repeated research, the present invention was developed by connecting a vertical part with an L-shaped cross section and an inclined part with a substantially L-shaped cross section, and forming a wide notch at the corner of the vertical part and the inclined part. There is approximately a right angle between both surfaces of both vertical pieces of the vertical part,
In addition, by forming an obtuse angle between the surfaces of both inclined pieces of the inclined part, and making an angle exceeding 180 degrees between the surface of the vertical piece and the surface of the inclined piece, the exterior decorative board has an inside corner joint member. The above-mentioned problem is solved by making it possible to extremely orderly join the substantially right-angled corner portions of the decorative boards.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 9.

A is a corner joining member in which a vertical portion 1 having an L-shaped cross section and an inclined portion 2 having a substantially L-shaped cross section are continuous in series.

The vertical portion 1 is formed by both vertical pieces 1a, 1a, and the two surfaces _1a1 , _1a1 are approximately at right angle (∠R=
90 degrees).

Further, the inclined portion 2 is also formed of both inclined pieces 2a, 2a, and the two surfaces _2a1 , _2a1 are formed at an obtuse angle. Specifically, the angle α added to the right angle is about 15 degrees or less, and the entire angle between the surfaces 2 _a1 and 2 _a1 is about 105 degrees. Its angle α
is determined by the inclination angle of the inclined surface 8 of the exterior decorative board C, which will be described later.

Further, the angle β between the surface 1 _a1 of the vertical piece 1 a and the surface 2 _a1 of the inclined piece 2 a that are continuous in series is greater than 180 degrees and within 270 degrees. This angle β is also determined by the inclination angle of the inclined surface 8 of the exterior decorative board C.

Vertical pieces 1a, 1a and inclined piece 2 continuous in series
Broadening notches 3, 3 are formed in a substantially V-shape symmetrically at the corners of a and 2a. This widening notch 3 is formed at ∠ in the stage before setting the angle β.
At 180 degrees, a normal notch is formed, and when molded to the angle β, it is widened to an appropriate width by tensile stress or the like. In actual production, the depth and width of the notch were determined while making it U-shaped so that cracks were less likely to occur due to the widening of the notch.

The size of the angle β and the widening notches 3, 3
It is directly proportional to the amount of spread. That is, the angle β is
The relationship is such that as the angle approaches 270 degrees, the amount of expansion of the expansion notch 3 increases.

Further, in the embodiment, the inclined portions 2 are continuous in series above the vertical portion 1, but the present invention is not limited to this, and the inclined portions 2 may be continuous in series below the vertical portion 1.

[Effect of idea]

In the present invention, a vertical portion 1 having an L-shaped cross section and an inclined portion 2 having a substantially L-shaped cross section are connected, and the vertical portion 1
A wide notch 3 is formed at the corner of the vertical portion 1 and the inclined portion 2, and both surfaces 1 of both vertical pieces 1a, 1a of the vertical portion 1 are formed.
The angle between _a1 and 1 _a1 is approximately a right angle, and the angle between 2 _a1 and 2 _a1 is an obtuse angle on both surfaces of both inclined pieces 2 a, 2 a of the inclined portion 2, and the surface 1 _a1 of the vertical piece 1 a and the surface 2 of the inclined piece 2 a. By using this as an inside corner joint member of exterior decorative laminates with an angle exceeding 180 degrees between _A1 and A1, firstly, it is possible to It is possible to install the parts in an orderly manner, secondly, the present invention can be provided at low cost, and thirdly, it can be easily and quickly installed.

To explain these effects in detail, first, when the exterior decorative board is composed of a vertical surface and an inclined surface as in the past, as shown in FIG. 10 and FIG. Both the cross-section of the vertical part a and the cross-section of the inclined part b of M are formed at right angles, and when viewed from the ridgeline direction, there is a gap between both inclined surfaces, as shown in FIG. is an obtuse angle, and even if it is forcibly fixed to both sides of both slopes b of the inside corner joining member M with rivets, etc., distortion will occur near the ends of both slopes of the exterior decorative board adjacent to the inside corner. This not only impairs the appearance, but also has the disadvantage that if the edges of the sloped surface are irregularly exposed, they may become a source of corrosion.

However, in the present invention, the two surfaces 1 a1 , 1 _a1 of both the vertical pieces 1 a, 1 a of the vertical portion 1 are approximately at right angles, and the two surfaces 2 a1 , 2 _a1 of the both inclined pieces 2 a, 2 a of the inclined portion 2 _{are made at a substantially right angle.} By making an obtuse angle between them, when the exterior decorative panels C and C having the sloped surface 8 are joined at the corner, the angle between the sloped surfaces 8 and 8 is an obtuse angle when viewed from the ridgeline direction at the end of the sloped surface 8. Even if it is, it is equivalent to an obtuse angle formed between both surfaces 2 _a1 and 2 _a1 of the inclined portion 2, and has the advantage that no forced external force is required and the installation can be done orderly and reliably. This is possible because the angle of the cross section of the inclined portion 2 of the corner joining member A is made to correspond to the degree of inclination of the inclined surface 8 of the exterior decorative board C.

Further, the corner joining member A, which exhibits such favorable effects, is integrally formed by press working and can be provided at an extremely low cost. In particular, since the notch part 3 is formed at the corner of the vertical part 1 and the inclined part 2, even if the vertical part 1 and the inclined part 2 are integrated by pressing the L-shaped metal material, the bending will not occur. It is possible to provide an extremely well-organized corner joining member A in which no cracks or the like occur at any location.

Further, when such an inside corner joining member A is used, joining construction at an inside corner location can be extremely simple and quick. That is, when the exterior decorative board C has the sloped surface 8 as in the past, there is no need to forcibly press or bend the sloped surfaces 8, 8 at the corner locations, and the construction process is simplified. can be done quickly and can be constructed reliably.

For this reason, it is possible to maintain the aesthetic appearance of the inner corner portions of the exterior decorative panels C and C for a long period of time.
