Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application 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 and a building. More specifically, even if the decorative surface width and the panel thickness are increased, the male and female fitting structures do not peel off from the wall base, and fixtures such as nails are not exposed to the outside. It relates to a panel that can be stretched horizontally.

[Conventional technology]

Conventionally, as a panel of this kind, a core material such as a synthetic resin foam is filled between metal plate materials and integrally formed, and a concave shape and a convex shape are formed at both end edges in the width direction to form a panel having the actual structure. Has been launched.

[Problems to be solved by the invention]

However, this type of panel has a disadvantage in that if it is fixed from the brain using nails, bolts, or the like to fix it to the frame, it cannot follow the deformation of the frame due to an earthquake or the like and is damaged. In the case of a large panel with a decorative surface width of about 600 to 900 mm, the conventional method is to perform a brain attack from the decorative surface, in which fixtures such as nails and bolts are exposed on the decorative surface. This significantly deteriorates aesthetics and weather resistance. In order to eliminate this defect, a method of fixing the panel by attaching a metal plate material serving as a back surface material with rivets from the back surface side has been devised, but basically, the surface material is not fixed to the frame. However, there was a disadvantage that the resistance to earthquake and wind pressure were poor. Further, one end of the back material is fixed, but the other end is free, and there is a disadvantage that the engaging force is inferior.

[Means for solving the problem]

In order to eliminate such defects, the present invention uses a metal plate material for the surface material and the back surface material, and has two insertion edges projecting in a substantially U-shaped cross section at one longitudinal edge of the surface material,
On the other end edge, two fitting grooves with a substantially U-shaped cross section are formed, and the back material is shaped to engage the back material of the adjacent panel on the fixed part side, and the front material and the back material are in contact The panel is fixed at one end so that it is not exposed to the outside by integrating it with a core material so that the panel is not exposed to the outside. Also, the panel is thermally expanded and contracted, and the panel is peeled off due to deformation of the frame (earthquake, etc.). It provides a panel that can prevent surface materials, pass a fire resistance test, and increase the width and thickness of the decorative surface, making it easy to apply.
