Description

[Detailed Description of the Invention] The present invention relates to corner structures for buildings, houses, storerooms, temporary houses, and the like. The purpose is to completely eliminate the exposure of nail heads, fixtures, etc. to the decorative panel surface that would impair the appearance, waterproofness, and corrosion resistance of the decorative surface in the corner, and to make installation extremely easy through elastic deformation. It has a reliable support structure with added elasticity, and the gap between the surface of the exterior material at the top corner and the edge of the decorative panel is closed through cushioning properties, etc. to improve waterproofness. The object of the present invention is to propose a corner structure that can be formed at low cost by simplifying the constituent materials and the corner structure.

In the conventional corner structure, most of the fixing nail heads were exposed on the decorative surface. As a result, the external appearance of the inside corner included dents from nail driving, paint for nail head treatment, and the like, resulting in an extremely poor external appearance. In addition, there is a known corner structure that attempts to improve this problem, such as Utility Model Publication No. 57-5403, but this has the drawbacks of a complicated structure, difficulty in attaching and detaching, and lack of waterproofness.

The present invention eliminates these drawbacks and provides a decorative surface with a beautiful appearance without dents or deformation, is easy to install, has a simple structure, is highly waterproof, is inexpensive, and can be installed reliably. We propose a possible corner structure.

18 mm, l ₄ l ₂ , H ₄ = about 3 to 20 mm. Furthermore, the waterproofing material 16 mainly closes the gap Δh between the engaging part 15 of the decorative panel 11 and the exterior material 4, and its shape is, for example, a cross section as shown in FIGS. 4a to 4m, and They are belt-shaped, rod-shaped, etc., which have cushioning properties, waterproof properties, a certain degree of flexibility, and are self-supporting in terms of workability during construction. In other words, figure a is a circular rod-shaped waterproofing material, figure b is an oval and rod-shaped waterproofing material, figure c is a square and rod-shaped waterproofing material, figure d is a hexagonal rod-shaped waterproofing material, and figure e is a semicircular waterproofing material. A long waterproof material provided with a tongue piece 16a, Figure f shows a long waterproof material partially provided with a tongue piece 16a as shown in Figure e, and Figure g shows a long waterproof material partially provided with a tongue piece 16b.
Fig. h shows a long waterproof material with a wedge-shaped tongue piece 16c, Fig. i shows a rod-shaped waterproof material with a wedge-shaped cross section, and Fig. J shows 3. A rod-shaped waterproofing material with a rectangular cross section. Figure K shows a waterproofing material with hot melt adhesive coated on the outer periphery of a hard core material. Figure 1 shows a waterproofing material with wire and synthetic resin wire as the core material, and a waterproofing material molded around the outer periphery. Figure m shows a bar-shaped waterproof material with a U-shaped cross section. The materials for the waterproof material 16 include rubber, synthetic rubber, sponge, plastic foam, elastic plastic, and among the above materials, inorganic materials,
It is made of one or more of fireproofing materials and adhesives, and has a certain degree of cushioning properties.

Next, a construction example will be explained.

It is now assumed that up to the exterior material 4 has already been constructed in order to form the corner structure shown in FIG. Therefore, the fixture 7 is fixed to the surface of the exterior material 4 existing at the corner with a nail 5 at P=600 mm. Next, a waterproof material 16, for example, made of synthetic rubber and having a diameter of 3 mm as shown in FIG. Plant vertically. In addition,
In this case, if it separates from this contact area, use adhesive or adhesive tape to partially fix it temporarily. Therefore, one engaging portion 15 of the decorative panel 11 as shown in FIG. As shown in A, the decorative surface part 1
3 to engage the engaging portion 15 at the other end with the locking tongue piece 10 at the other end as shown by the solid line, thereby forming the inside corner 6. As a result of this engagement and integral construction, the gap Δh was completely closed by the waterproof material 16. Further, the engaging portion 15 of the decorative panel 11 was engaged with the locking tongue piece 10 of the fixture 7 via the waterproof material 16 with the elasticity of the decorative panel itself being applied. In addition, when connecting the decorative panels 11, as shown in FIG. 6, the locking part 15 at the lower end of the decorative panel 11 located above is set at H ₄ (approximately 10 to 50 mm) as shown in FIG. All you have to do is cut it out.

What has been described above is only one embodiment of the corner structure according to the present invention, and the corner of the fixing part 9 of the fixture 7 is formed flat as shown in FIG.
The corners can also be reinforced. Further, the decorative panel 11 can also be formed as shown in FIGS. 8a to 8i. That is, in Figure A, a gap 14a is provided between the inclined side surface 14 and the engaging portion 15, and θ ₅ is 90° and θ ₄
Decorative panel with obtuse angle, figure b shows l ₃ of the engaging part 15
Fig. c shows a decorative panel with an L-shaped inclined side surface 14, Fig. d shows a decorative panel in which the opening of the engaging part 15 is widened in a slope, and Fig. e shows an engaged panel. Figures f to h show a decorative panel in which the portion 15 is a wider opening, figures f to h show a decorative panel in which the inclined side surface 14 is formed at a right angle or an acute angle, and figure i shows a decorative panel in which the corners of the decorative surface part are flattened. Further, although not shown, the fixture 7 can also be formed into a hanger shape. In addition, although not shown, a plurality of nail attachment holes may be drilled in the fixing piece 8 of the fixture 7, or the decorative panel 1
Of course, it is also possible to use an embossed plate for 1.

As described above, according to the inside corner structure according to the present invention, the elastic part formed with the engaging part on the back side of the side edge of the decorative surface part is attached to the fitting that is fixed at an appropriate pitch on the exterior material of the inside corner part. Since the decorative panel with the decorative panel is engaged and attached through elastic deformation, no fixing tools such as nail heads appear on the decorative surface, and a corner structure with a beautiful appearance can be achieved. In addition, construction is very easy because the installation structure uses elasticity, and since it can be supported with elasticity added at all times, it is more reliable. Furthermore, since the waterproof material can sufficiently close the gap between the inner corner exterior material surface and the engaging portion of the decorative panel through its cushioning properties, the waterproof property can be significantly improved. Furthermore, there is an advantage that the construction of the waterproofing material is easy because the mounting tool is used as a guide. In addition, the fixtures and decorative panels have a simple shape, so they can be mass-produced and can be produced at low cost.
