Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to architectural panels (hereinafter simply referred to as panels) useful for constructing the outer and inner walls of buildings and structures. More specifically, even if the decorative surface width and panel thickness are increased, the male and female mating structure will not peel off from the wall base, and fixing tools such as nails will not be exposed to the outside.
This relates to panels that can be hung vertically or horizontally.

[Conventional technology]

Conventionally, as this type of panel, there have been many panels having a laminated structure of a surface material, a core material, and a back material, panels made of ceramics such as cement, and the like. These panels can be broadly classified into a butt structure, a real serpentine structure, an interlocking structure, and a connecting part of a hook structure.

[Problem to be solved by the invention]

However, this type of panel has the disadvantage that if nails, bolts, etc. are used to fix it to the frame, and if it is fixed from above, it cannot follow the deformation of the frame due to earthquakes, etc., and it may break. Furthermore, when the surface material of these panels is metal, they are unable to follow the expansion and contraction caused by heat, resulting in deformation of the decorative surface and a significant deterioration in design. Furthermore, there was no panel that had a structure in which the panel was fixed from the front side of the surface material, and the back surface was also fixed, so that the fixing tools were not exposed to the outside. There was also a problem with fire resistance.

[Failure to solve the problem]

In view of these points, the present invention uses thin metal plates for the front and back materials, has a structure that prevents the front and back materials from coming into contact with each other, and furthermore, even if the front and back materials are fixed to the structure at the same time, there is no leakage from the outside. The present invention provides a panel having a structure in which fixing tools are not exposed.

〔Example〕

This is the part that functions as a fixing part to fix the to the building frame. The concave fixing groove 10 also serves to form a gap in the connecting portion between the panels Δ when the panels A are connected, prevent capillary phenomenon, and strengthen waterproofness. Furthermore, the reinforcing piece j1 is used to reinforce the side of the male connecting part on the surface material, and as shown in FIG. When the fixture β is installed,
The reinforcing piece 11 is also fixed by the fixture β, which prevents the insertion edge 7 from being pressed and deformed by the lower surface 15 when the insertion edge 7 is inserted into the fitting groove 16, and serves to securely fix the insertion edge 7. It is something. The female type connecting part 1 has an upper surface 14 with the lower edge of the side wall 4 bent inward, a lower surface 15 with the tip of the upper surface 14 bent outward, and the upper surface 14 and the lower surface 15 are formed into a substantially U-shaped cross section. It consists of a fitting groove 16, a reinforcing piece 17 with the tip of the lower surface 15 projecting inward, and an engaging edge 18 consisting of the lower surface 15, the back material 2, and the core material 22. This fitting groove 16 is a portion that is engaged with the insertion edge 7 of the male connector valve and fixes the panel A to the frame body α. Note that the step 2b formed on the decorative surface 2a
, 2c are designed to make the decorative joints step-like to make the joint parts clearer. The back material ■ is as shown in Figure 3.
A rising piece 20.2 with both ends of a long plate protruding upward
A gutter-like portion 19a is formed from the core material 22.
Panel A is made into a Zandwidge structure by covering the back side of the panel, improving the mechanical strength of panel A itself, and also using a noncombustible sheet,
It serves as a function such as waterproof membrane, heat shield sheet, water absorption sheet, soundproof sheet, parakink material, etc., and its material may be the same material as the surface material, or asbestos paper, kraft paper, Asqual 1-Felt. , metal foil (Afl, Fe, Pb, Cu), synthetic resin sheet, rubber sheet), cloth sheet, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc., laminated with one or more types, It is made of sheets that have been treated to be waterproof and flame retardant. As shown in the figure, the reinforcing pieces 11.17 are installed in a stretched manner with a gap formed between them and the top of the surface material in order to improve fire resistance.
70 can be arranged on the front side and the back side. The core material 22 is mainly made of synthetic resin foam, which functions as a heat insulator, waterproof material, soundproof material, cushioning material, fireproof material, etc., such as polyisocyanurate foam, phenol foam, polyurea foam, etc. Polyimide four 1
, etc., and these synthetic resin foams contain flame retardants, (borates, silicates, phosphates, etc.), flame retardant aids (
gypsum slag, talc, shirasu balloons, etc.), aggregates (perlite, glass peas, etc.), fibrous materials (long and short fibers), etc. Coating phenol foam powder around pearlite and adding dirt. Foamed by heat and pressure, gypsum board, rock wool board, glass wool board, ALC, insulation board, wood chip board, glass wool, etc., made of a single material or a combination of multiple materials. It is.

In addition, the core material 22 is formed by filling the top surface material and the gutter-like portions 19a for the back surface material, and reinforcing pieces 11 and 17 in the figure.
This is to prevent contact between the top and the vertical edge pieces 20 and 21, and even if the surface material is heated due to a fire, that heat will not be transmitted to the back surface material, and the fire resistance will be improved by preventing thermal bridges. This is intended to improve the quality of life. Furthermore, the relationship between the opening widths W, W2 of the gutter-like portions 1a and 19a for the front surface material and for the back surface material is W.
