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 fitting 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 a drop-in panel 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 upper mold has many panels with a butt structure, a jitsugi structure, a mutually interlocking structure, and a connecting part of the hook structure, which are integrated with a core material made of synthetic resin foam. 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, in the case of large panels with a decorative surface width of 600 to 9001 cm, the usual construction method has 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, if the front and back materials are metal plates, the front and back materials will come into contact at the joints, and in the event of a fire, the heat from the front material will be transferred to the back material at the joints, which are the weakest points. This causes a problem with fire resistance, as it can cause a so-called thermal bridge and cause the joint to be destroyed.

[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 the fixing tools are not exposed to the outside, and it also prevents the panel from thermal expansion, contraction, and It prevents panel peeling and surface material from peeling off due to deformation of the building frame (earthquakes, etc.), passes fire resistance tests, and
The present invention provides a drop-in type panel that allows the width and thickness of the decorative surface to be increased.
