This fixture 7 has a fixing part 8 in contact with the end of the exterior material 4 at the inside corner and is fixed via a fixture 5 such as a nail, so it has the function of preventing the edge of the exterior material 4 from flapping. It also has The material for the fixture 7 is one that has a certain degree of rigidity for locking the decorative panel 10, such as a surface-treated steel plate, Gulfuan, aluminum plate, stainless steel plate, spring plate, copper plate, or the like. Furthermore, the size of the fixture 7 is W ₁ = 20
~200mm, H ₁ = 30~300mm, plate thickness around 0.2~3mm,
θ ₁ is 90°, θ ₂ is an acute angle, and W ₂ = about 2 to 10 mm. Note that since θ ₂ is an acute angle, the decorative panel 10 described below is locked with a force that presses it to the inside corner. Further, the mounting pitch P of the fixture 7 varies depending on the purpose, but is approximately 450 to 1000 mm. The decorative panel 10 forms the appearance of an inside corner, and also engages with the fixture 7 through elastic deformation of the decorative panel 10 itself to form the inside corner 6 integrally.
To explain further, the decorative panel 10, as shown in FIGS. 1 and 3, is made by molding a long elastic plate material, for example, a plate material made of the material of the above-mentioned fixture 7, and has an isosceles shape in cross section. The decorative surface portion 11 with an angle of θ ₃ =90°, the narrow sloped side surface 12 whose both side edges are bent outward with respect to the central angle θ ₃ , and the cross section facing toward the decorative surface portion 11 at the tip of the sloped side surface 12 . A U-shaped engaging portion 13 is provided. The angle θ ₄ between the decorative surface portion 11 and the inclined side surface 12 can be any angle such as an acute angle, a right angle, or an obtuse angle, but the obtuse inclined side surface 12 allows the decorative panel 10 to be in a stable state in terms of the force relationship when engaged. While supporting on the exterior material 4,
It also serves to reinforce the engaging portion 13. Furthermore, the angle θ ₅ of the engaging portion 13 with respect to the decorative surface portion 11 is formed to be an obtuse angle, and the decorative panel 10 is engaged with the locking tongue piece 9 of the fixture 7, and the decorative panel 10 is attached to the inner corner portion. useful for. To explain further, the inclined side surface 1
2 forms a space with a distance of ΔG between the fixing part 8 of the fixture 7 and the decorative surface part 11 of the decorative panel 10, so that the engaging part 13 is not exposed on the surface of the decorative surface part 11, and the decorative panel This is to secure a space for temporarily reducing θ ₃ when engaging the fitting 7 with the fitting 7 . In addition, even if a lateral force is applied to the decorative panel 10 after the decorative panel 10 is engaged with the fixture 7, the spring effect of the bent portion at the boundary between the inclined side surface 12 and the engaging portion 13 and the decorative Surface part 1
1, and the locking tongue piece 9 of the fixture 7
This does not affect the engagement relationship between the engagement portion 13 and the engagement portion 13, and the engagement state can be maintained reliably. Furthermore, to explain the size and angle using FIGS. 1 to 3, the width W ₃ of the decorative surface portion 11 = W ₁ −△
G, W ₄ = 5 to 15 mm, W ₄ ≧W ₅ , W ₅ ≧△W, W ₆ ≧
△W, H ₂ =inner corner length. Note that ΔG is the vertical distance between the back surface of the decorative surface portion 11 and the surface of the exterior material 4 as shown in FIG. 1, and ΔW is the height of the locking tongue piece 9 as shown in FIG. Moreover, θ ₂ ≒180°−θ ₅ .
