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 panels that can be stretched vertically and horizontally.

[Conventional technology]

Conventionally, as this type of panel, a metal plate material as a surface material, a sheet-like material as a back surface material, a butt structure integrated with a core material made of synthetic resin foam, a real groove structure,
Numerous panels having a connection structure having a fixed structure and a hook structure have been put on the market.

[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. Further, when the front and back members are metal plate members, the front and back members come into contact at the connecting portion, and the heat of the front member is reduced at the connecting portion, which is the weakest point in the event of a fire. Propagation to the side, that is, a so-called thermal bridge, may break the connecting portion, and there is a problem in fire resistance. In the male and female connection structure, rainwater leaks from between the connection parts due to wind and rain, etc., and it is considered that caulking material, packing material, etc. are interposed between the connection parts. There was a problem in terms of workability, cost, productivity, and workability (uneven joint width).

[Means for solving the problem]

The present invention omits such points, while using a metal plate material for the surface material and the back surface material, the structure inserted into the surface material,
By forming a tongue-and-groove structure using the front material, the core material, and the back material, and integrating the front material with the core material so that the back material does not contact, the panel is fixed at one end and is not exposed to the outside To prevent the panel from peeling due to the thermal expansion and contraction of the panel and the deformation of the frame (earthquake, etc.) and the peeling of the surface material, pass the fire resistance test, and furthermore, the width of the decorative surface,
An object of the present invention is to provide a panel which can be made thicker and can maintain waterproofness without intervening a caulking material or a packing material in a connecting portion.
