Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building panel useful for constructing an outer wall and an inner wall of a building or a building. More specifically, the present invention relates to a building panel in which a core material is sandwiched between metal plates.

[0002]

2. Description of the Related Art The long-side joints of this type of rectangular panel have a connecting portion of a tongue-and-groove structure, a close-fitting structure and a hooking structure, while the short-side joints are mainly of a butt structure. In a very rare case, a structure is adopted in which the core material and the back surface material on the short side are removed, and the surface material is bent inward into an L-shape.

[0003] For the joint on the long side, for example,
As disclosed in JP-A-290869 and JP-A-2-27963, there has been proposed a panel in which the fixing material of the panel is covered with a surface material and is not exposed on the surface, so that the panel fits easily. However, even in these proposals, nothing is mentioned about the joining portion on the short side, and it is considered that a butt structure conventionally used is adopted.

In a butt structure, as shown in FIG. 4, it is very common to use a hat-shaped fitting cover metal for a butt portion. However, the method of using the hat-type fitting cover metal requires a lot of complexity and attention, such as sealing of the cover metal to a panel surface material or a base material and sealing work for preventing infiltration of rainwater and the like. One of the biggest drawbacks of building panels is the aesthetics, and as a result of many improvements, the joints on the long sides are covered with a surface material covering the adhesive of the panels. In addition, while establishing a method of not exposing to the surface side, in the joint portion on the short side side, the fitting cover metal protrudes to the surface side, thereby significantly impairing the aesthetic appearance.

In order to make up for this drawback, a structure is employed in which the surface material is bent into an L shape along the core material at both ends on the short side. However, in this case, it is not sufficient to bend only into an L shape, and the following fixing method is required. Furthermore, the bending step at the boundary between the decorative surface of the panel and the decorative surface of the male fitting portion hinders three-dimensionally when bending the surface material into an L-shape, maintaining a beautiful L-shape. It is difficult to do so, and if you forcibly bend it, an irregular wrinkle will occur in the bent part. When bending both ends on the short side, it is not enough to bend only into an L-shape. To firmly fix the panel to the base material, bend it into an L-shape and then add a reinforcing material. Use a method such as mounting, bulb tight, etc., and mounting to the base material.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a building panel having a joint suitable for joining with vertically and horizontally adjacent panels, and to reduce wrinkling of a surface material when manufacturing the panel.
