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 male and female mating structure will not peel off from the wall base, and fixing tools such as nails will not be exposed to the outside.
This relates to panels that can be hung vertically or horizontally.

[Conventional technology]

Conventionally, this type of panel used metal plate material as the surface material,
A sheet-like material is used as the backing material, and the core material made of synthetic resin foam is used to create a butt-butted structure, a zigzag structure, and a mutually interlocked structure. has been done.

[Problem to be solved by the invention]

However, this type of panel has the disadvantage that if nails, bolts, etc. are used to fix it to the frame, and if it is fixed from above, it cannot follow the deformation of the frame due to earthquakes, etc., and it may break. In addition, in the case of large panels with a decorative surface width of about 600 to 900 mm, the usual construction method has traditionally been to pierce the surface from the decorative surface, which exposes fixings such as nails and bolts on the decorative surface. This resulted in a significant deterioration in aesthetics and weather resistance. Furthermore, the backing material of this type of panel is a sheet-like material, so-called kraft paper, aluminum kraft paper, etc., which has no rigidity, and there are many disadvantages in terms of the mechanical strength of the panel itself, and the connecting parts may be damaged due to fire etc. It was destroyed, and there were also problems with its fire resistance.

[Means to solve the problem]

Taking these points into account, the present invention uses metal plate materials for the front and back materials, and forms engagement grooves with a substantially U-shaped cross section on both ends of the front material in the longitudinal direction. By using a drop-in structure and integrating the front and back materials with a core material so that they do not come into contact with each other, the panel can be fixed at one end and not exposed to the outside, and it also prevents the panel from thermal expansion, contraction,
The present invention also provides a panel that prevents peeling of the panel and surface material due to deformation of the frame (earthquake, etc.), improves fire resistance, and allows the width and thickness of the decorative surface to be increased.
