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 was made by filling a core material such as synthetic resin foam between metal plates to form an integral structure, and forming concave and convex shapes on both edges in the width direction to create a real structure. is covered.

[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 of aesthetics and weather resistance. In order to eliminate this drawback, a method has been devised in which the panel is fixed by attaching the metal plate material that serves as the back surface material to the back side using a ripping head, etc., but basically the surface material is not fixed to the structure. For,
It had the disadvantage of being inferior in earthquake resistance and wind pressure resistance. Further, although one end of the backing material is fixed, the other end is free, which has the disadvantage of poor engagement force.

[Means for Solving the Problems] In order to eliminate such drawbacks, the present invention uses a metal plate material for the front surface material and the back surface material, and has a protrusion having a substantially U-shaped cross section on one longitudinal edge of the surface material. Two fitting grooves having a substantially U-shaped cross section are formed on the other edge of the two insertion edges, and the back material is shaped to engage the back material of adjacent panels on the fixed part side, Furthermore, by 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 the fixing tools are not exposed to the outside. To provide a panel that prevents panel peeling and surface material peeling due to deformation (earthquakes, etc.), passes a fire resistance test, can increase the width and thickness of the decorative surface, and is easy to construct.
