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. In more detail, even if the decorative surface width and panel thickness are increased, the male and female mating structure will not fall off from the frame, and fixing tools such as bolts will not be exposed to the outside, vertically and horizontally. It relates to stretchable panels.

[Conventional technology]

Conventionally, many panels of this type have been proposed, such as panels with a laminated structure of a surface material, a core material, and a back material, panels made of ceramics such as cement, and the like. These panels can be broadly classified into a butt structure, a real serpentine structure, an interlocking structure, and a connecting part of a hook structure.

[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, a method has been devised in which the back material is fixed from the back side with rivets or the like so that the fixing tool is not exposed to the outside, but this method has disadvantages in terms of ease of construction and poor wind pressure resistance.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention forms a real structure at the ends in the width direction of the front material and the back material, and further forms a dropped structure on the top of this real structure, the so-called surface material,
A panel is provided in which a synthetic resin foam or the like serving as a core material is filled between a front surface material and a back surface material.
