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 panel thickness are increased, the male and female mating structures do not peel off from the wall base, and fasteners such as nails are not exposed to the outside, and the surface, The present invention relates to a panel in which the back surface can be used as a decorative surface and further has improved fire resistance.

[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 a nail, a bottle, or the like is used to fix the panel to the frame, and the panel is fixed from the brain, it cannot follow the deformation of the frame due to an earthquake or the like, and may be 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, there is no panel having a structure in which the back material side can be used as a decorative surface.

[Means for solving the problem]

In order to eliminate such a defect, the present invention considers that the inside direction of the building panel is inward and the opposite direction is outside,
One metal plate material is a horizontally long decorative surface portion, a side edge in which one side edge of the decorative surface portion is bent inward at one edge in the width direction of the decorative surface portion, and an upper edge in which a lower edge of the side wall is bent inward. An engaging groove bent in a substantially U-shape in cross section from a lower edge protruding by bending the tip of the upper edge inward and projecting the tip outward, and extending the lower edge of the engaging groove outward. Form a fixed edge consisting of a fixed piece,
On the other end edge, a side wall that is bent inward on the other side edge of the decorative surface portion,
An insertion edge consisting of an underground ground with the end of the side wall protruding outward is formed, and the insertion edge of one metal plate material and the fixed edge side of the other metal plate material face each other, and the metal plate material is formed. To provide a panel integrated with a core material so as not to come into contact with each other while being shifted left and right.

Panel A in which the workability and durability of the caulking material treatment at the joints where the panel A ends face each other at the time of panel A construction are improved, and (b) is a caulking material, packing material, etc. in the engaging groove 8. Panel A, in which 30 is integrally formed, FIG. (C) shows that the core material 27 is covered with a sheet-like material 31 such as a synthetic resin foam so that liquid does not leak from between the plate materials 1 and 14 when discharged with a raw material. Panels A and (d) show panels A and (e) on which a raising material, a refractory material (inorganic material), and a backup material 32 functioning as a liquid leakage preventive member are formed to prevent the plate member 1 from contacting the plate member 14 . ~ (g) figure using what the plate 1 and the plate member 14 of the same shape, species by their stacked state It is a deformed panel A. Of course, a panel A in which FIGS. 5 (a) to (u) to 9 (a) to (g) are combined can also be used.

〔The invention's effect〕

According to the panel of the present invention as described above,
Large panels can be fixed without exposing fixtures such as nails and bolts to the decorative surface. Since the fixing portion is formed on both metal plates, either of the plates can be used as a decorative surface.
Since the structure is such that the metal plate members do not come into contact with each other even at the connection portion, a panel with greatly improved fire resistance is obtained. Panels with improved waterproofness, airtightness, earthquake resistance, heat insulation, soundproofing, and workability. There are features and effects such as.
