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,
The present invention relates to a panel which can be stretched vertically and horizontally and has enhanced waterproofness.

[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 and uses a metal plate material for the surface material and the back surface material, and has an engagement groove having a substantially U-shaped cross section at one longitudinal end of the surface material and an outer groove at the other end. An insertion edge protruding from the surface material is formed into an insertion structure, integrated with a core material so that the front surface material and the back surface material do not come into contact with each other, and interrupted in the longitudinal direction in the engagement groove of the surface material or the insertion edge. By forming island-shaped protrusions (hereinafter simply referred to as protrusions), the fixing of the panel is prevented from being exposed at one end and outside, and the panel is thermally expanded and contracted, and the panel is deformed due to deformation of the frame (such as earthquake). To prevent the peeling of the surface material and the surface material, to pass the fire resistance test, and to increase the width and thickness of the decorative surface.In addition, the waterproofness without intervening caulking material and packing material in the connection part It provides a panel that can be maintained.
