Description

[Detailed Description of the Invention] The present invention relates to a corner panel used for the exterior corner of a building.

Conventionally, for the exterior corners of buildings, flat exterior materials are pressed together into a key shape, and an L-shaped joiner made of metal or synthetic resin is attached to the key-shaped outer corner. Since it is made of a different material, it creates a different texture and bulges against the surface of the exterior material, which does not harm the aesthetics, and it is difficult to apply a uniform finish to the exterior material.

Therefore, the present invention aims to provide a corner panel that does not have a foreign texture or bulges on the exterior material in the construction state, can be applied with a uniform finishing coat, and has excellent strength.

Hereinafter, one embodiment of the present invention shown in FIGS. 1 to 3 will be explained. 1 is a flat exterior material made of magnesium carbonate, 2 is a corner panel, and has the same thickness as the exterior material 1. A flat substrate 3 made of the same magnesium carbonate as the raw material was used, and as shown in FIG. A W-shaped bending groove 6 having an intermediate portion 5 is formed in the bending groove 6, the substrate 3 is bent with an adhesive interposed in the bending groove 6, the bending groove 6 is closed, and the intermediate portion 5 is bent. Chamfered part 7 on the corner
An L-shaped panel 8 having a
A bonding surface portion 10 made of adhesive is provided spanning both side pieces 9, 9, and caulking notch steps 11 are formed at the outer edges of both side pieces 9, 9, respectively. In addition,
The removable tape 4 is peeled off at an appropriate time after the adhesive on the bending groove 6 and the adhesive surface portion 10 has solidified.

When constructing the corner panel 2 as described above on the corner of the exterior of a building, as shown in FIG. A notch step 14 and a notch step 11 of the side piece 9 are adjacent to the piece 9 and provided at the surface edge of the exterior material 1.
A caulking material 15 is filled into the joints formed by the above, thereby forming a building exterior corner, and a finishing coat is applied to the surface of the corner panel 2 together with the surface of the exterior material 1 and the surface of the caulking material 15.

In this construction state, since the corner panel 2 is made of the same material as the exterior material 1, there is no difference in appearance, and the finish coating of the corner panel 2 against the exterior material 1 is uniform. In addition, the bonding strength at the bent groove 6 portion in the closed state is increased by the adhesive surface portion 10 formed across the two adjacent side pieces 9, 9. Due to the chamfered portions 7 at the corners, damage is unlikely to occur due to impact to the outer corners. Furthermore, when the corner panels 2 are stacked as shown by the imaginary line in FIG.
This type of storage can be stacked and does not take up unnecessary space.

The bending grooves of the corner panels are as shown in Figures 4 and 6.
As shown in the figure, the intermediate portions 16 and 17 may be made smaller, and portions of both side pieces 18 and 19 of the L-shaped panel may have bent grooves 20 and 21 directly adjacent to each other at the inner corners, respectively.
Alternatively, the intermediate portion 24 may have a trapezoidal bent groove 22 as shown in FIG. 5, or the bent groove 23 as shown in FIG. 7, but if the intermediate portions 16 and 17 are too small, the bent groove 20 and 21 becomes difficult, and if the upper base 25 of the trapezoidal intermediate portion 24 is too large, the adhesive on the adhesive surface portion 26 at the inner corner will be attached to both side pieces 2.
7 and 27 becomes difficult and the strength bottoms out.
Therefore, it is desirable to form the bent grooves within a range that does not cause such problems.

As described above, the present invention forms a bending groove in an inorganic substrate of the same type as the inorganic exterior material, leaving a middle part, and by closing the bending groove, a chamfered part is formed at the outer corner of the middle part. While forming an L-shaped panel with a substrate,
The surface of the type panel is formed by the surface of the substrate, and an adhesive surface is provided at the inner corner of the L-type panel spanning both sides of the L-type panel, so that the exterior surface does not deteriorate in the construction state. There is no uneven texture on the material, and the finish coating can be applied uniformly, and in combination with the adhesive surface section provided at the inner corner that spans both sides and the closing of the bending groove, it is possible to create a smooth finish at the bending groove. It has excellent adhesive strength, and the chamfered part makes it difficult to be damaged even by impact to the outer corner, and this chamfered part can act as a space for the adhesive surface when stacking, so it does not take up much space when stacked and stored. It is very effective, and unlike the bending method that leaves a space in the groove, the bending is done by closing the bending groove, so only a small amount of adhesive is applied to the bending groove, and the product can be made easily. In addition to being able to reduce costs, the bending position of the board can be determined by closing the bending grooves, which has the effect of preventing product variations.Furthermore, the surface of the L-shaped panel is made of the same inorganic substrate surface as the exterior material. Because of this, during construction, the paint is applied with the same finish as the surface of the exterior material, resulting in good adhesion of the paint, making it difficult for paint to peel off, and resulting in an exterior corner that maintains an equilibrium moisture content and has excellent weather resistance. In addition, unlike the case where a connecting thin layer of a substrate and a separate material is laminated on the surface, the surface of the L-shaped panel is formed of an inorganic substrate surface, so the surface of the L-shaped panel itself is difficult to peel off. effective.
