Description

TECHNICAL FIELD The present invention relates to a building panel (hereinafter, simply referred to as a panel) useful for constructing an outer wall and an inner wall of a building, a structure. More specifically, even if the decorative surface width and the panel thickness are increased, the male and female fitting structures do not come off from the wall base, and the fasteners such as nails are not exposed to the outside, and vertical, The present invention relates to a panel that can be installed horizontally.

[Conventional technology]

Conventionally, as this type of panel, a metal plate material is used as a surface material, a sheet-like material is used as a back surface material, a butt structure integrated with a core material made of synthetic resin foam, an actual perforated structure,
A large number of panels having a joint structure of a phase-fixing structure and a hooking structure are on the market.

[Problems to be Solved by the Invention]

However, in this type of panel, if nails, bolts, etc. are used to fix the body to the body, and the body is fixed from the brain, it is not possible to follow the deformation of the body due to an earthquake or the like, and there is a disadvantage that it is damaged. In the case of a large panel with a decorative surface width of 600 to 900 mm, hitting the surface from the decorative surface has been the usual method of construction, which exposes fasteners such as nails and bolts on the decorative surface. The aesthetics and weather resistance are greatly deteriorated. Further, when the front and back materials are metal plate materials, the front material and the back material come into contact with each other at the connection part, and the heat of the surface material is generated on the back material side at the connection part which is the weakest point in case of fire. There was a problem in fire resistance because it spreads to the so-called heat bridge and may break the connecting part.
In addition, this kind of panel has a male and female connection structure on the surface material side and is only fixed to the body by the connection by the surface material, and the back material only functions as a reinforcing material that covers the back surface of the core material. None, the backing material did not contribute to the engagement of the panel at all.

[Means for solving the problem]

In the present invention, such a point is omitted, and metal plate materials are used for the surface material and the back surface material, and an engaging groove and a fitting groove having a substantially U-shaped cross section are formed at both end edges in the longitudinal direction of the surface material. In addition to the drop structure, a male and female mating structure is also formed on the back material, and the front material and the back material are integrated with the core material so that they do not contact each other, so that the panel can be fixed at one end and at the other. Prevents the tool from being exposed to the outside, prevents panel peeling due to thermal expansion and contraction of the panel, and body deformation (earthquake etc.) and surface material, passes the fire resistance test, and even the width of the decorative surface. It provides a panel with a large thickness and easy construction.
