Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to architectural panels (hereinafter simply referred to as panels) useful for constructing the outer and inner walls of buildings and structures. 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.

[Prior Art] Conventionally, as shown in FIG. 10, this type of panel has been constructed by connecting panels a having a real structure on the back side with a male-female fitting structure, and attaching a panel al to a wall base α. A method has been devised in which the end of the holder is fixed with a fixture β.

[Problems to be Solved by the Invention] However, a gap T is formed between the panels a+ and 32 by the head of the fixture β, and this large gap T allows rainwater etc. blown up from the joint to flow into the wall base. 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 aI by the fixture β. There were drawbacks such as rusting of β and infiltration of rainwater from the fixing holes into the wall base α.

Furthermore, the fixture β was visible from the outside due to the gap between the joints, resulting in a greatly inferior aesthetic appearance. In addition, although the end of the back material on the fixed part side is fixed by the fixture β, the end of the back material on the lower end side is only fixed by the insertion edge C of the surface material, so earthquakes and wind pressure When an external force is applied due to a fire or the like, one end of the front surface material and one end of the back surface material are held down only by the strength of the insertion edge C, which has the disadvantage of lacking connection strength. Furthermore, there has been no panel in which the back material can also be used as the wall surface, or a panel in which the front material and the back material can be used alternately or randomly as the wall surface.

[Means for Solving the Problems] In order to eliminate such drawbacks, the present invention fixes the panel at one end, and also fixes the panel from the surface side of the front material or back material, by fixing the panel at the male connecting portion. The fixing groove is covered by the upper surface of the female connecting part to cover the fixing tool,
In addition, by forming a drop-in structure with approximately the same shape on the front and back materials, the wall surface can be used as either the front or back material of the panel, and the surface that is not fixed by the fixtures The edges of the panel and back panel are fixed by the front panel and back panel, respectively, which are fixed with fixing tools, thereby providing a panel that can be securely fixed to the wall base.

When the back material mold is used as the wall surface as shown in FIG. 4(b), the insertion edge 23 is inserted into the fitting groove 31 of the female joint portion (to be described later) and fixed to the wall base α. It is also a part that functions as a fixing part for fixing the panel A to the wall base α by driving a fixing tool β such as a nail into the fixing groove 26. Further, the concave fixing groove 26 is formed to be larger than the height and width of the nail head of the fixing tool β, so that the fixing tool β does not protrude above the surface of the joint basement 21, and the panel A is not engaged. When doing so, no gap is formed in the contact area between the upper surface 29, the joint base 21, and the upper edge 24, which will be described later, and the fixing groove 26 forms a gap to prevent capillary phenomenon and strengthen waterproofness. It is something. The female connecting portion 28 has an upper surface 29 that is bent inward at the lower edge of the side wall 20, a lower surface 30 that is bent outward at the tip of the upper surface 29, and is formed into a substantially U-shaped cross section from the upper surface 29 and the lower surface 30.
