Abstract

PURPOSE:To ensure securing of a panel and to improve heat resistance and earthquake resistance by a method wherein a surface material of a plate and a back material, both formed by a plate made of a metal, are formed integrally through a core, and both edges in the longitudinal direction of the surface material form insertion structure. CONSTITUTION:A surface material 1 and a back material 23 are formed with a plate made of a metal, and are integrally formed through the medium of a core 26 in a manner to make no contact with each other. An engaging groove 8 formed approximately in a U-shape in cross section and an engaging recessed groove 9 are formed in the one edge in the longitudinal direction of the surface material 1, and an out insertion edge 17 approximately in a U-shape in cross section and an insertion lower edge 21 are formed in the other edge to form insertion structure in which the insertion edge 17 is inserted in the engaging groove 8 and the insertion lower edge 21 is inserted in the engaging recessed groove 9. This constitution enables securing of a panel by securing only the one edge of the surface material 1 to a body and enables prevention of exposure of a fixing bolt from an outer surface.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of 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, and the vertical , relates to an insert-type panel that can be hung horizontally.

[Conventional technology]

Conventionally, this type of panel used metal plate material as the surface material,
There are many panels that use a sheet-like material as the backing material and have a butt structure, a cylindrical structure, an interlocking structure, and a connecting part of the hook structure, which are integrated with a core material made of synthetic resin foam (
It is covered with cloth.

[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, 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. The heat may spread to the sides, creating a so-called thermal bridge, and the connecting portion may be destroyed, posing a problem with 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 an engagement groove and an engagement groove each having a substantially U-shaped cross section on one longitudinal edge of the surface material. , the other end edge is formed with an insertion edge having a substantially U-shaped cross section outward and a lower insertion edge, and the insertion edge is inserted into the engagement groove and the insertion lower edge is inserted into the engagement groove. In addition, 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 not exposed to the outside.
In addition, the insert type prevents panel peeling and surface material from peeling off due to panel thermal expansion, contraction, and deformation of the frame (earthquakes, etc.), passes fire resistance tests, and can increase the width and thickness of the decorative surface. This panel provides the following panels.
