Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a sandwich panel used for repairing buildings, structures, or existing exterior walls, and has heat insulation, soundproofing,
This relates to sand inch panels with improved earthquake resistance and wind pressure resistance.

[Conventional technology]

Panels used to form the exterior walls of buildings of this type, such as warehouses, using sandwich panels include metal siding materials with plastic foam integrally interposed between a thin metal plate having male and female joints and kraft paper; A sandwich panel in which a plastic foam is interposed, an uneven part is formed on the longitudinal side wall, and this is inserted.
Ceramic siding mainly made of LC, cement, calcium silicate, etc. is known.

[Problem to be solved by the invention]

However, conventional metal siding materials have a synthetic resin foam interposed between the surface material and a sheet-like material such as kraft paper, and have a male-female connection structure, with only one end fixed. When the decorative width is about 400 mm and the thickness is about 25 mm or more, there are disadvantages in that the siding material tends to come off easily, the decorative surface becomes mountain-like, and it becomes difficult to insert and insert the male and female type connecting parts. Furthermore, the sandwich panel has a structure in which bolts are used to connect the panel to the top, so it lacks aesthetics and has the disadvantage of having to be constructed using a crane or the like. Of course, ALC1 ceramic siding material is heavy,
The decorative surface and thickness were also limited, making it difficult to install and susceptible to freezing.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention includes a square or rectangular decorative surface, side walls protruding downward on four side edges of the decorative surface, and a lower end of each side wall protruding outward. The decorative surface of this surface material is filled into a box-shaped recess surrounded by side walls, and among the projecting pieces! Excluding the protruding piece, it is composed of a core material that bulges out and fills the back surfaces of the other three protruding pieces with equal thickness, and a backing material that covers at least the back side of the core material, resulting in heat insulation, soundproofing, and earthquake resistance. , proposes a sandwich panel with improved wind pressure resistance, etc.

[Example] The sandwich panel according to the present invention (
An example (hereinafter simply referred to as a panel) will be described in detail. That is, FIGS. 1(a) to (C) are a perspective view and an end view showing examples of the above-mentioned panel, and the soil is a surface material, such as a surface-treated steel plate, a zinc-nickel alloy plated steel plate, an aluminum-zinc plated steel plate, etc. Consists of one type of alloy plated steel sheet (product name Galfan, Galvalume steel sheet, Super Zinc), fluororesin coated steel sheet, vinyl fluoride laminated steel sheet, stainless steel sheet, aluminum sheet, aluminum alloy sheet, copper sheet, clad steel sheet, vibration damping steel sheet, etc. A metal plate (including a flat plate and an embossed plate) or a synthetic resin plate is formed by press molding, injection molding, extrusion molding, roll molding, etc., or a combination of these. That is, on the surface material, there is a square or rectangular decorative surface 2, a side wall 3 formed by projecting the four side edges of the decorative surface 2 downward at right angles or at an angle, and the side wall 3 of the side wall 3. The lower end is formed into a substantially hat-shaped cross section from a protruding piece 4 which protrudes outward substantially parallel to the decorative surface 2. In addition, it is preferable that the four side walls 3 are integral and continuous with each other as shown in the figure. This is to prevent leakage of the core material 5 when a synthetic resin foam or the like is discharged as a raw material and reacted and foamed to form the core material 5, which will be described later, and to improve the design of panel A. be. Of course, it is also possible to form the four side walls 3 separately. The core material 5 is a heat insulating material, a soundproofing material, a raising material,
It functions as an adhesive, reinforcing material, or fireproofing material, and its materials include synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, cement, and mortar. It can be discharged, molded, hardened, self-adhesive, or made of a molded body. In addition, when using a molded body as the core material 5, an adhesive (
(not shown) is required. To explain further, synthetic resin foams are mainly used as the core material 5, such as resins for polyurethane foam, resins for phenol foam, resins for polyisocyanurate foam, polystyrene foam, etc.
Phenol foam resin is coated around pearlite and foamed by heating and pressurizing it, and these are combined with flame retardants and flame retardant aids (borax, sodium metaborate, antimony trioxide, calcium carbonate, aluminum hydroxide). , bentonite, pearlite grains, shirasu balloon,
It is made by adding or laminating one or more of asbestos, various fibers, etc. In particular, when fire resistance is desired, pearlite grains are densely filled on the surface material and the space between the back material 6, and the voids between the pearlite grains are filled with phenol foam containing asbestos fibers to form an integrated panel. If it is A, it will be able to pass the fireproof structure test. In addition, when using a phenol foam-based synthetic resin for the core material 5, anti-rust paint is applied to the surface material and the back material 6 to prevent the acidic components of the core material 5 from coming into direct contact with the surface material and the back material 6. By applying it to the back surface, it is also possible to prevent rusting on the surface material when the back surface material 6 is a metal plate. To explain further, the core material 5 is surrounded by the decorative surface 2 on the surface material and the side wall 3 as shown in FIG. At the same time, it is made to protrude downward to the same thickness from the entire lower surface area including the back surface of the other three protruding pieces 4 except for the back surface of one protruding piece 4a among the four protruding pieces 4. It was filled with Therefore, when the panel A is constructed, the cushioning properties of the core material 5 make it possible to absorb the vibrations of the base. The back material 6 covers at least the back surface of the core material 5 to give the panel A a sandwich structure, and improves the mechanical strength of the panel A, and also includes backing material, fireproofing material, waterproofing material, sound absorbing material,
It has the function of a mold release agent, etc., and is made of the same material as the above-mentioned surface material (metal plate, synthetic resin plate), or sheet-like material, such as asbestos paper, kraft paper, asphalt felt, metal foil (All! , Fe, Pb.
