Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a construction panel (hereinafter simply referred to as a panel) useful for constructing an exterior wall or a wall of a building or structure. More specifically, even if the decorative surface width and panel thickness are increased, the panel has a male-female mating structure that will not peel off from the wall base, and will not expose fixing tools such as nails to the outside. be.

[Conventional technology]

Conventionally, as shown in FIG. 10, this type of panel has been constructed by connecting panels a with a real structure on the back side using a male-female mating structure, and fixing the ends of panels a to the wall base α. A fixing device using a tool β has been devised.

[Problem to be solved by the invention] However, a gap T is formed between the panels al and 32 by the head of the fixing tool β, and rainwater etc. blown up from the joint part is absorbed by the wall base due to this large gap T. There was a drawback that it was transmitted to the α side and corroded the wall base α. In addition, since the fixture β is formed near the joint, rainwater, etc. will directly reach the head of the fixture β and the fixing hole drilled in the panel a by the fixture β. There were drawbacks such as rusting of the fixture β and infiltration of rainwater from the fixing holes into the wall base α.

Furthermore, the fixture β was visible from the outside through the gap between the joints, resulting in a greatly inferior aesthetic appearance. In addition, the end of the back material on the fixed part side is fixed by the fixing tool β,
Since the end of the back material on the lower end side is fixed by the insertion edge C of the surface material, there is a risk of it coming off from the insertion edge C if external force such as an earthquake or fire is applied.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention fixes the panel at one end, and also fixes from the surface side of the surface material by covering the fixing groove of the male connector with the upper surface of the female connector. This covers the fixtures, and the drop-in structure improves workability.Furthermore, the ends of the front and back materials that are not fixed by the fixtures are covered by the front and back materials that are fixed by the fixtures, respectively. To provide a panel that can be fixed to a wall base.
