Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a building panel used as a wall material for a building.

[Conventional technology]

In general, as a building panel of this type, a fireproof board such as a calcium silicate board or a gypsum board bonded to a back surface of a shallow box-shaped metal panel made of a metal plate is widely used.

[Problems to be solved by the invention]

However, in the above-mentioned building panel, the back surface (non-bonding surface) and the four peripheral end surfaces of the fire-resistant board were exposed, so the fire-resistant board was invaded by rainwater or condensed water after the construction panel was attached to the building frame. When water is absorbed, a warp or undulation is generated on the panel surface to make the appearance unsightly, and the strength of the fire-resistant board part is reduced. Therefore, it is possible to bond a metal plate to the back surface side of the fireproof board to form a water impermeable layer, but it is not possible to prevent water absorption from the four peripheral end faces of the fireproof board. Also, since the fireproof board is heavy, it is also possible to adhere a honeycomb material such as an aluminum honeycomb sheet to the back surface side of the metal panel and to bond the metal plate to the back surface side of the honeycomb material (the opposite side of the metal panel bonding surface) to form a Saint-Gerache structure. It is conceivable that even in this case, invasion of water from the four peripheral end faces of the honeycomb material is unavoidable, and this water corrodes the aluminum foil constituting the honeycomb sheet, lowering the strength and deteriorating the flatness of the panel surface. There is a problem of inviting.

This invention was made in consideration of the above conventional points,
It is an object of the present invention to provide a highly durable construction panel that can prevent water from entering the inside of the panel and prevent corrosion of the backing material and the back surface of the metal panel and water absorption of the backing material.

[Means for solving problems]

The building panel of the present invention is a metal panel in which a bent piece portion is continuously provided on the four circumferences of a main plate portion, and an edge plate portion substantially parallel to the main plate portion is continuously provided at the tip of the bent piece portion. And a backing material adhered to the back surface side of the main plate portion of the metal panel, and a flat water-impermeable plate having a peripheral edge portion adhered to the edge plate portion and covering the backing material and the back surface side of the metal panel. It is a building panel with a back plate made of.

In the present invention, as the metal panel, various metal plates such as a steel plate, a copper plate, a stainless plate, and an aluminum plate formed in a shallow box shape can be used, and in particular, an enamel panel provided with an enamel layer at least on its surface side. Is preferable in terms of durability.

In this invention, as the backing material, a honeycomb material such as an aluminum honeycomb sheet or a paper honeycomb sheet subjected to a flame-retardant treatment is used, which is preferable in terms of weight reduction, but a fireproof board such as a calcium silicate plate can also be used.

Further, as the backing material in this invention, a metal plate such as a zinc iron plate, a color iron plate, an aluminum sheet, or a flat plate made of various materials such as a plastic plate that prevents water from permeating can be used.

[Action]

In the building panel of the present invention, the back side of the backing material and the metal panel is covered with a back plate made of a water impermeable plate to prevent water from entering the inside of the back plate panel.
This prevents corrosion of the backing material and the back side of the metal panel, prevents the panel strength from decreasing, and prevents the backing material from deforming due to water absorption or corrosion, thus suppressing a decrease in the flatness of the panel surface. A good appearance is maintained.

〔Example〕

A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is a metal panel, which is a enamel panel in which a 1.6 mm thick decarburized steel plate for enamel is bent and the enamel layer is baked on the surface side, 2 is its main plate part, 3 is this main plate part 2
The bent piece portions 4 continuously provided for four weeks are frame-shaped edge plate portions substantially parallel to the main plate portion 2 formed by bending the upper end portion of the bent piece portion 3 inward of the panel. Reference numeral 5 denotes an L-shaped metal fitting which is fixed to the bent piece portion 3 by welding or riveting.

On the other hand, 6 is an aluminum honeycomb sheet as a backing material, which is adhered to the back surface 2a side of the main plate portion 2 of the metal panel 1 with an adhesive. The total thickness H of the aluminum honeycomb sheet 6 is the edge plate portion 4
The height h of the outer surface of the aluminum plate is approximately equal to the outer surface of the aluminum plate, and a back plate 7 made of a zinc iron plate having a thickness of 0.5 mm is adhered to the outer surface of the edge plate portion 4 and the back surface 6a of the aluminum honeycomb sheet 6 with an adhesive.

In the building panel 8 having the above structure, the back plate 7 and the edge plate portion 4 are adhered to each other to prevent water from entering the inside of the metal panel 1, and the aluminum honeycomb sheet 6 and the edge plate portion 4 of the back plate 7 are prevented. A strong reinforcing member is formed on the back surface side of the main plate portion 2 integrally with the above to improve the strength and rigidity of the entire building panel 8.

FIG. 3 shows a second embodiment of the present invention, in which the same or corresponding parts as those in FIG. 1 are designated by the same reference numerals as those in FIG. 1 and their explanations are omitted (the same applies to other embodiments hereinafter). . In this embodiment, the total thickness H of the aluminum honeycomb sheet 6 is the height h of the edge plate portion 4.
In the case of a smaller size, a backing plate 11 made of a metal plate as a strength member is bonded to the back surface 6a of the aluminum honeycomb sheet 6, and the back plate 7 is bonded only to the edge plate portion 4. The back plate 7 can be made of a plastic plate or a thin metal sheet if it is not necessary for strength.

In each of the above examples, an aluminum honeycomb sheet is used as the backing material, but a fireproof board may be used as the backing material to obtain a construction panel having the same configuration as described above. In this case, as shown in the third embodiment of FIG. 4, when the total thickness H of the refractory board 14 which is the backing material is smaller than the height h of the edge plate portion 4, the refractory board 14 is different from the aluminum honeycomb sheet 6. Unlike the backing plate 11 (see FIG. 3), the refractory board alone can provide strength and rigidity without using the backing plate 11.
Can be omitted.

FIG. 5 shows a fourth embodiment of the present invention in which the total thickness H of the refractory board 14 is larger than the height of the edge plate portion 4, but a flat back plate 7 is used. Since the back plate 7 is adhered to the edge plate portion 4 via the spacer 15 made of a rubber plate (or a resin plate), and the back plate 7 does not require press molding, it can be manufactured at low cost.

Next, in a fifth embodiment of the present invention shown in FIG. 6 and FIG. 7, a metal panel 21 in which a bending direction of an edge plate portion 22 connected to the bending piece portion 3 is different from those of the above-described respective embodiments. I am using. That is, the edge plate portion 22 is formed by bending the upper portion of the bent piece portion 3 outward of the panel to be formed substantially parallel to the main plate portion 2. The back plate 7 is composed of the edge plate portion 22 and the backing material. It is adhered to both of certain aluminum honeycomb sheets 6. As shown in FIG. 7, the edge plates 22, 22 adjacent to each other at the four corners of the metal panel 21 may be integrated by welding a triangular plate-shaped connecting piece 23, but the connecting piece 23 may not be provided. When the cutout is left as it is, a sealing material is applied to the joint portion between the corner portion 24 and the back plate 7 at the time of adhering the back plate, and the corner portion 2
It is preferable that 4 has a watertight structure.

In addition, also in the said 2nd-4th Example, it can replace with the metal panel 1 and can use the metal panel 21 of 5th Example.

The present invention is not limited to the above-described embodiments, and for example, the material and thickness of each part may be other than the above.

[Effect of device]

As described above, according to the present invention, since the entry of water into the interior of the building panel is prevented by the storage plate, it is possible to prevent corrosion of the backing material and the back surface of the metal panel and water absorption of the backing material,
It is possible to obtain a building panel having high strength and durability with little reduction in flatness of the panel surface.

In addition, the back plate is flat and easy to process, and since it only needs to be adhered to the edge plate of the metal panel, it can be easily attached to the metal panel. The panel construction cost is low because it has a simple structure with the edge plates connected in series.
