Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a laminated panel, and more particularly to a laminated panel in which a non-metal non-combustible panel and an aluminum honeycomb panel are superposed.

[Prior Art] Non-combustible panels made of non-metal such as ceramic panels and marble have good decorative properties, but have little strength against bending. In order to increase the strength, the panel must be thick. On the other hand, the honeycomb panel made of aluminum has high strength against bending, is lightweight, and is excellent in sound absorbing properties, heat insulating properties, shock absorbing properties, and the like.

Therefore, a laminated panel in which an aluminum honeycomb panel is superposed and reinforced on a thin non-metal non-combustible panel has been developed and used for construction or the like. For example, the fourth
As shown in the drawing, there is known a laminated panel 90 in which an aluminum honeycomb panel 92 and a ceramic panel 94 are joined with an adhesive 96 (for example, epoxy adhesive).

[Problems to be Solved by the Invention] However, since the honeycomb panel 92 made of aluminum and the ceramic panel 94 have different coefficients of thermal expansion, the laminated panel 90 has a problem that a joint portion is peeled off due to a temperature change and a ceramic panel. There is a problem that cracks and the like occur in the 94. Further, since the two panels are joined by the adhesive 96, the laminated panel 90 of this type has heat resistance,
It lacks reliability in terms of weather resistance, durability and corrosion resistance.

Further, in order to join the two panels 92 and 94 with the adhesive 96, it is necessary to perform appropriate pretreatment, pressurizing and heating work at the time of joining, and thus it takes a lot of time to manufacture the laminated panel 90.

Therefore, the present invention has been made for the purpose of providing a laminated panel which is excellent in shear strength and peel resistance and can be easily manufactured.

[Means for Solving the Problems] The gist of the present invention is to provide a laminated panel in which a non-metallic non-combustible panel and an aluminum honeycomb panel are superposed on each other, wherein the non-metallic non-combustible panel and the aluminum honeycomb panel are combined. While providing a cushioning member made of an elastic body between, at least one projection is provided on one plate surface of the non-metal non-combustible panel, through holes corresponding to the projection in the aluminum honeycomb panel. When the non-metal non-combustible panel and the aluminum honeycomb panel are laminated with the cushioning member in between, the non-metal non-combustible panel and the aluminum are attached to the projections penetrating the through holes. The laminated panel is characterized in that a fixing member for fixing the honeycomb panel to the laminated state is provided.

[Operation] The non-metal non-combustible panel and the aluminum honeycomb panel are laminated with the cushioning member interposed while inserting the protrusion of the non-metal non-combustible panel into the through hole of the aluminum honeycomb panel. Therefore, a fixing member is attached to the protrusion to fix the non-metal non-combustible panel and the aluminum honeycomb panel in a laminated state. Since the two panels are firmly laminated by such a simple assembly, this laminated panel has strong peel resistance and is easy to manufacture.

In the laminated panel thus manufactured, even if the two panels expand and contract at different thermal expansion coefficients due to temperature changes, the displacement between the two panels is absorbed by the cushioning member, so that the laminated panel is excellent in shear strength.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a partially broken perspective view showing a laminated panel of an embodiment, and FIG. 2 is a sectional view taken along the line AA of FIG.

The laminated panel 1 is formed by laminating an aluminum honeycomb panel (hereinafter simply referred to as a honeycomb panel) 5 and a ceramic panel 7 with a rubber cushioning member 3 in between, and is used with the ceramic panel 7 as a surface. For example, it is used as a wall material or floor material for construction.

The honeycomb panel 5 is a panel in which a honeycomb core 10 is sandwiched from both sides by an upper surface plate 12 and a lower surface plate 14, and both sides of the honeycomb core 10 are covered with a brazing material (not shown). (Brazing sheet) is applied and heated to be integrally joined. The honeycomb core 10 is, for example, an aluminum plate (J
It is formed into a honeycomb shape with a cell size of 3/4 inch and a height of 25 mm by using IS standard BA23PC). The upper plate 12 and the lower plate 14 have a thickness of 1 mm with a brazing material layer (not shown) coated on one side, and a vertical length. It is an aluminum plate (JIS standard BA7PC) of 1800 mm and 900 m in width.

Through holes 16 are formed at the four corners of the honeycomb panel 5, and the through holes 16 have collars 18a with collars 1a.
8 is inserted. The color 18 is, for example, 2mm heat
Of aluminum alloy (JIS standard 5056). The inner diameter of the collar 18 is slightly larger than the outer diameter of the protrusion 20 of the ceramic panel 7, which will be described later.

The honeycomb core 10 can use not only a honeycomb-shaped core material but also a core material composed of cells of various shapes such as a triangle and a quadrangle. Further, as the upper and lower face plates 12 and 14, for example, brazing filler metal (JIS standard BA400
Various plate materials such as those coated with 4) can be used.

The ceramic panel 7 has the same size as the honeycomb panel 5 (length 1800 mm × width 900 mm), has a thickness of 8 mm, and has cylindrical protrusions 20 at the four corners at positions corresponding to the through holes 16. It is provided. An annular groove 20b is engraved in the vicinity of the protruding end portion 20a of the protrusion 20. When the two panels 5 and 7 are stacked with the cushioning member 3 in between, the annular groove 20b is almost the same as the collar 18a of the collar 18. Come in line.

The cushioning member 3 has the same size as the two panels 5 and 7 (vertical 1
800 mm x 900 mm in width) and the thickness is 1 mm,
Through holes (not shown) through which the protrusions 20 of the ceramic panel 7 pass are provided at the four corners. Since the two panels 5 and 7 have different coefficients of thermal expansion, a deviation occurs due to a temperature change in the laminated state, but this deviation is absorbed by the cushioning member 3.

Next, the assembly of the laminated panel 1 will be described.

First, the honeycomb panel 5 and the ceramic panel 7 are superposed with the cushioning member 3 interposed therebetween. Then, the projecting portion 20 of the ceramic panel 7 penetrates the through hole 16 and the through hole, and the projecting end portion 20 a of the projecting portion 20 is exposed on the upper surface plate 12 of the honeycomb panel 5. Here, when the E-shaped retaining ring 30 (made of steel) as a fixing member is fitted into the annular groove 20b of the protrusion 20, the E-shaped retaining ring 30 comes into contact with the collar 18a of the collar 18, and the collar 1
The ceramic panel 7 and the honeycomb panel 5 are fixed in a laminated state with the aid of 8. The inside of the collar 18 and the protrusion 2
There is a small gap between the ceramic panel 7 and 0, but this is to prevent the ceramic panel 7 from being damaged by thermal expansion. That is, expansion and contraction of the honeycomb panel 5 and the collar 18 due to temperature change are absorbed in this gap.

The dimensions and materials of each member of the laminated panel 1 configured as above are summarized in Table 1.

Next, the strength of the laminated panel 1 will be examined by the following test. This test was also performed on conventional laminated panels, and the comparison results are shown in Table 2. Incidentally, the size of the conventional laminated panel honeycomb panel and ceramic panel,
The thickness and material are the same as those in the example.

One of the tests is performed in the plane direction of the laminated panel 1, and the honeycomb panel 5 and the ceramic panel 7 are sheared by applying a load of 50 kg in opposite directions (directions of arrows M and N in FIG. 2). Inspect the durability to the following (hereinafter referred to as shear inspection). The other one is performed in a direction perpendicular to the surface direction, and the resistance against peeling is tested by applying a load of 50 kg to the two panels in opposite directions (arrow O and arrow P in FIG. 2) ( Hereinafter referred to as peeling inspection).

As described above, in the laminated panel 1 of this embodiment, the E-shaped retaining ring 30 is firmly fixed to the laminated state of the two panels 5 and 7, and the buffer member 3 is the two panels 5 due to the temperature change.
And the deviation of 7 are absorbed. Therefore, the laminated panel 1 is excellent in shear strength and peel resistance.

Further, the two panels 5 and 7 are laminated with the cushioning member 3 in between, and the E-shaped retaining ring 30 is attached to the protrusion 20 of the ceramic panel 7.
Since it can be manufactured simply by mounting, it does not require any trouble in manufacturing. In the case of a conventional laminated panel in which two panels are bonded together using an epoxy adhesive, it takes time until sufficient adhesive strength is obtained (for example, it takes several days for natural drying), The laminated panel 1 can be assembled in an extremely short time.

Although the protrusions 20 are provided at the four corners of the ceramic panel 7 in the above-described embodiment, it goes without saying that an appropriate number may be provided according to the size of the laminated panel.

In addition, although a ceramic panel is used as the non-metal non-combustible panel in the above-described embodiment, natural or artificial marble, gypsum board, siding board, or the like may be used. I used an E-shaped retaining ring 30 as a fixed part,
Besides, a C-shaped retaining ring or a split pin may be used.

Further, as shown in FIG. 3 (A), a resin washer 40 is provided between the E-shaped retaining ring 30 and the collar 18a of the collar 18.
You can put it in. The E-shaped retaining ring 30 is made of steel and has a collar 18
Also, since the honeycomb core 10 is made of aluminum, electrolytic corrosion occurs when it is exposed to rain, etc. However, by inserting the washer 40, electrolytic corrosion can be prevented.

Furthermore, as shown in FIG. 3B, the two panels may be directly fixed by the thick E-shaped retaining ring 32 without the collar 18. In this case, the number of parts can be reduced and the manufacturing cost can be reduced.

[Effects of the Invention] As described above, according to the laminated panel of the present invention, two panels are firmly laminated by simple assembly, so that the laminated panel has strong peel resistance and is easy to manufacture.

Further, in the laminated panel, even if the two panels expand and contract at different thermal expansion coefficients due to temperature changes, the displacement between them is absorbed by the cushioning member, and therefore the shear strength is excellent.
