CONSTITUTION:The metal front face member 1 is not brought into contact with the metal rear face member 11 even in a connection to prevent heat bridge by forming the metal front face member 1 and the metal rear face member 11 so that the ends of them have spaces 1 and 20 at a position of a fixing section 21 in the connection of a building panel A to face each other in the building panel A with a sandwich construction forming a core 18 between the metal front face member 1 and the metal rear face member 11 to form male and female type connecting constructions on both side ends.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to architectural panels (hereinafter simply referred to as panels) used to form vertical or horizontal wall bodies as exterior or interior materials for buildings and structures.

0002

[Prior Art] Conventionally, a panel has a thin metal plate as a surface material, and a synthetic resin foam and a metal back material are laminated on the back side of the metal surface material with male and female connecting portions formed on both longitudinal edges.
Alternatively, there are many panels on the market in which fireproof granules such as perlite and borax are mixed into a synthetic resin foam.

0003

[Problem to be Solved by the Invention] However, since there are fire prevention regulations in order to use this type of panel as an exterior wall, it is necessary to pass various tests such as a fire prevention structure test.
If only a synthetic resin foam such as flame-retardant polyisocyanurate foam or phenol foam was used as the core material as in the former case, it would be difficult to pass these types of tests. In addition, in the latter case, it is difficult to uniformly mix fire-retardant granules into the synthetic resin foam without inhibiting the foaming of the synthetic resin foam, resulting in a lack of reliability in fire protection tests and a slowdown in production speed. Combined with the use of multiple raw materials, this method had the disadvantage of increasing costs. Furthermore, in this type of panel, the metal front and back materials form a thermal bridge at the joints, resulting in a reduction in heat insulation and fire protection. In addition, there was a risk that the metal front and back materials would form a thermal bridge at the joints, causing condensation.

0004

[Means for Solving the Problems] In order to eliminate such drawbacks, the present invention provides a panel in which a core material is formed between the front and back metal materials, which is fixed to the frame using a fixing device such as a screw. We propose a panel that prevents thermal bridges between the metal front and back materials and improves fire protection, heat insulation, and condensation resistance by placing the ends of the metal front and back materials on a certain fixed part. It is something to do.

The fixing part 21 is made up of fixing pieces 6, 17, and a core material 18, and is a part for fixing the panel A to the frame body α using a fixing tool β such as a screw, and the fixing tool β is driven into the gap 19 at Δt. Therefore, the frame α
When the fixing tool β is cast into the structure, when the fixing tool β spins idle (when the building body α is a steel base), the panel A does not rise above the building body α, and the front and back materials 1 and 11 and the core material 18 separate. There will be nothing left to do. Note that the lower edge 5 can also be used as a fixing part. 18 is a core material, which is filled in a gutter-like part surrounded by the decorative surface 2, the male connecting part 3, and the female connecting part 7 of the surface material 1, and is mainly used in panel A.
It is made of one or more materials that provide heat insulation properties to the material and have secondary functions such as adhesives, noncombustible materials, cushioning materials, soundproofing materials, and shape-retaining materials. Specifically, it is made of synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, calcium silicate board, wood wool cement board, etc.
It is made of raw materials that are discharged, molded, hardened, and self-adhesive, or it is made of a molded body. In addition, when using a molded body as the core material 18, an adhesive (not shown) is required between the core material 18, the surface material 1, and the back material 11. To explain further, a synthetic resin foam is mainly used as the core material 18, such as polyurethane foam, phenol foam, polyisocyanurate foam, polystyrene foam, or perlite, and a phenol foam resin is coated around the core material 18. Foam that is compressed and foamed, and one type of flame retardant or flame retardant aid (borax, sodium metaborate, antimony trioxide, calcium carbonate, aluminum hydroxide, bentonite, perlite particles, shirasu balloon, asbestos, various fibers). It consists of things with the above added. In addition, when using a phenol foam-based synthetic resin for the core material 18, it is also possible to apply an anti-rust paint to the back surface of the surface material 1 so that the acidic component of the core material 18 does not come into direct contact with the surface material 1. be.
