DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building panel (hereinafter simply referred to as "panel") useful for constructing a building, an outer wall and an inner wall of a building. More specifically, even if the decorative surface width and the panel thickness are increased, the male and female fitting structures do not peel off from the wall base, and fixtures such as nails are not exposed to the outside. It relates to a panel that can be stretched horizontally.

[0002]

2. Description of the Related Art Conventionally, as a panel of this type, as shown in FIG.
Together with connecting the male and female fitting structure, Stationary has been devised by the wall base fixture ends of the panel a ₁ in alpha beta.

[0003]

However, a gap γ is formed between the panels a ₁ and a ₂ by the head of the fixing tool β, and rainwater and the like blown up from the joints b are formed by the large gap γ. There is a defect that the light is transmitted to the wall base α side and corrodes the wall base α. In addition, since the fixing tool β is formed near the joint portion b, rainwater or the like directly reaches the head of the fixing tool β and the fixing hole formed in the panel a ₁ by the fixing tool β. There were drawbacks such as rusting of the tool β and infiltration of rainwater into the wall foundation α from the fixing holes. Furthermore, the fixing tool β was visible from the outside through the gap in the joint portion b, and the aesthetic appearance was significantly poor. Further, the reinforcing piece c formed by being interposed in the core material is fixed by the fixing tool β, but when the panel a ₁ is fixed by the fixing tool β, the reinforcing piece c is deformed, and It was extremely difficult to cast, which was a major drawback in construction. Furthermore, the panel a ₂ protrusion d
When the physical thickness is thin and a physical pressure is applied to the joint b from the outside, the protrusion d is easily deformed, and the joint b is deteriorated in appearance and waterproofness of the joint b. In addition, in the event of a fire from the outside, the panel a is deformed and bent by heat, and the projection d is bent outwardly and deformed outward, thereby increasing the voids in the joints b. It has reached the back side and has a disadvantage of poor fire resistance.

[0004]

According to the present invention, in order to eliminate such a disadvantage, the panel is fixed at one end, and the fixing groove of the male connecting portion and the female member are fixed from the front side of the surface material. The fixture is covered by the upper surface of the mold connecting part side,
