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.
The present invention relates to a panel that can be stretched vertically or horizontally, and is useful for creating a structure in which the end of the butt end is sealed with caulking material.

[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 a core material made of synthetic resin foam or the like is used to create a butt-butted structure, a cylindrical structure, a mutually interlocking structure, and a large number of panels with connecting parts for the hook 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. Furthermore, when the surface material of these panels is metal, they are unable to follow the expansion and contraction caused by heat, resulting in deformation of the decorative surface and a significant deterioration in design. Furthermore, there has not been a panel that has a structure in which the panel is fixed from the front side of the front material and the back material is also fixed so that the fixing tools are not exposed to the outside. In addition, the edges of this type of panel in the width direction, the so-called end surfaces, are in a state of uncut edges, and if caulking material is planted in the vertical joints between the panel edges that are formed when the panels are horizontally stretched, The caulking material and the panel are only bonded to the edges of the surface material in a minute area, and the bonding to the synthetic resin foam hardly contributes to the strength. As a result, the adhesion between the caulking material and the panel is easily damaged by external forces or weather-resistant deterioration, and the filling process requires skill and requires a long period of time to achieve a beautiful appearance. was there. Furthermore, this type of panel had the disadvantage of poor fire resistance.

(Means for Solving the Problem) The present invention takes advantage of these points, uses metal plates for the front and back materials, has a structure that prevents the front and back materials from coming into contact, and further improves the width of the front and back materials. The panel is provided with an L-shaped end wall formed on the side edge thereof, which is bent inwardly and outwardly.
