Abstract

PROBLEM TO BE SOLVED: To provide a composite panel constituted so as to prevent the heavy exterior panel material bonded to the surface of a heat insulating panel material comprising a foamed material from peeling off to fall and excellent in fire resistance and fireproof properties. SOLUTION: A large number of holes 4 are provided to one surface of a heat insulating panel material 1 comprising a foamed material of which both surfaces are sandwiched between surface materials 2, 3 and an adhesive 5 is applied to the surface material so as to be rubbed in the holes 4 and an exterior panel material 6 is laminated to the adhesive coated surface material. Since the rear heat insulating panel material 1 and the surface exterior panel material 6 are directly laminated at the places of the holes by the adhesive 5, the exterior panel material 6 is prevented from peeling off to fall after execution by vibration or the like. In order to enhance fire resistance and fireproof properties, isocyanurate foam having fire retardancy itself is used as the foamed material of the heat insulating panel material. As the adhesive, a heat-resistant one is used.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite board used as an exterior or interior material of a building, and more particularly, to a heat insulating board made of a foam material and a heavy exterior board such as a ceramic industry. It relates to a composite plate.

[0002]

2. Description of the Related Art Conventionally, as one of building materials, there is a heat insulating plate made of a material having a very high heat insulating effect such as an isocyanurate foam or a rigid urethane foam. Since these foamed materials have a closed cell structure, they have properties of extremely high heat insulating effect and extremely low water absorption and moisture permeability. In addition, the specific gravity is very low, around 0.03. Although it is a material with such various characteristics, it must be certified as a flame-retardant material by itself, but it cannot be a non-combustible or semi-non-flammable material, and it cannot be certified as fire-resistant or fire-resistant. Therefore, at the present time, it is commercialized as a composite board by bonding other ceramic-based exterior panel materials.

When such a composite board is used as an exterior or interior material of a building, if it is fixed to a base material by nailing or the like, there is no problem in the bonded portion. However,
In recent years, the use of decorative panels for exterior and interior materials has become overwhelmingly common. In this case, the method of holding the decorative panel with nails from above is not a good method from the viewpoint of aesthetics and values. Recently, it has been practiced to attach it to a base using metal fittings.

[0004]

In the construction method using metal fittings described in the prior art, grooves for fixing metal fittings are formed on the side surfaces of a heat insulating plate made of a foamed material such as isocyanurate foam or rigid urethane foam. A metal fitting is put in the groove and fixed. However, in many cases, heat insulation boards made of these foam materials are sandwiched with aluminum foil, kraft paper, or other surface material on both the front and back surfaces. When the plates are bonded together, there is a problem that the heavy outer plate is peeled off at the face material and falls for a long time due to vibration such as an earthquake or other reasons.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to remove a heavy exterior plate material stuck on the surface of a heat insulating plate material made of a foam material and to drop. It is another object of the present invention to provide a composite board which is excellent in fire resistance and fire resistance.

[0006]

In order to achieve the above object, a composite plate according to the present invention is provided with a plurality of holes on one surface of a heat insulating plate made of a foamed material sandwiched on both sides by face materials, An adhesive is applied to the face material so as to be slid into these holes, and an exterior plate material is bonded thereon.

[0007] By using isocyanurate foam as the foam material of the heat insulating plate, the fire resistance is improved.

The use of a heat-resistant adhesive also results in excellent fire resistance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing a state in which a heat insulating plate and an exterior plate constituting a composite plate of the present invention are separated from each other.
FIG. 4 is a cross-sectional view showing a bonded state. In the figure, reference numeral 1 denotes a heat insulating plate made of a foam material, and face materials 2 and 3 are attached to both surfaces thereof. Then, a plurality of holes 4 are provided in the heat insulating plate 1 from above the surface material 2 on one side, and an adhesive 5 is applied over the entire surface material so as to be slid into these holes 4. The exterior plate 6 is attached from above.
The composite plate is attached to the base using metal fittings instead of nailing. Therefore, the left and right end surfaces of the heat insulating plate 1 are provided with grooves 7 for fixing metal fittings.

[0010] As a foam material constituting the heat insulating plate 1,
Materials similar to those conventionally used, such as isocyanurate foam and rigid urethane foam, are used.
In the case of building exterior and interior materials, those having a thickness of about 10 to 50 mm are used.

Here, the isocyanurate foam has a strong nurate bond, which prevents carbonization and progress of combustion during combustion and has a high ignition point. Therefore, this flame-retardant foamed material is used for a heat insulating plate. Thereby, a composite plate having high fire resistance and fire resistance can be obtained.

In addition, since isocyanurate foam has glass fibers in the center in the form of a mat and has excellent bending strength, a composite plate using this is expected to be used in a place where such characteristics can be utilized. It is suitable.

As the face materials 2 and 3, the same sheets as those conventionally used are used. That is,
According to the use of the composite board, a face material having a special function such as aluminum foil, resin-reinforced aluminum foil, kraft paper, glass paper, or glass fiber reinforced paper is appropriately used. In some cases, the same sheet is used on both sides of the heat insulating plate,
Different sheets may be used on the front and back.

As the adhesive 5, it is preferable to use a heat-resistant adhesive from the viewpoint of fire resistance and fire resistance of the composite plate.
The amount of the adhesive applied is limited to some extent. That is, if the amount is too large, it does not dry easily, causing poor adhesion, later warpage or rash. Therefore, if the extra part is inserted into the hole, the adhesion becomes tougher and the bending strength increases, and at the same time, the extra part can be applied as much as it enters the hole. Will also rise.

The hole 4 formed in the heat insulating plate from above the face material is
From the viewpoint of processing, a conical or cylindrical shape is preferable.In addition, in order to improve the fire resistance and fire resistance by rubbing a heat-resistant adhesive, increase the number of holes and provide holes of various sizes to create a flat surface. It is preferable to reduce the diameter as much as possible, and the depth of the hole may be appropriately determined in relation to the thickness. Then, in order to sufficiently fill the heat-resistant adhesive, a hole 4 having a depth up to just before the back surface as shown in FIG. 3 or a hole 4 penetrating the back surface as shown in FIG. It is good to By doing so, it is as if the pillars of the heat-resistant adhesive were erected, and the surrounding flame-retardant isocyanurate foam, for example, was further protected from the flame. Here, the diameter and pitch of the holes 4 vary depending on the type of the exterior plate material to be attached to the surface, but the hole diameter is about 2 to 5 mm, and the pitch is 1 to 3 m.
m is desirable. These may be appropriately determined depending on the material and weight of the exterior plate material to be attached to the surface.

As the exterior plate material, a ceramic material is used. Specifically, a square decorative plate made of a calcium silicate plate, a cement pearlite plate, a fiber-mixed cement plate, or the like is used.

In the composite plate having such a configuration, since the exterior plate and the heat insulating plate are directly bonded not only on the surface of the face plate but also with the adhesive in the hole,
Even if the weight of the exterior plate material is large, it does not peel off due to vibration or impact. When a heat-resistant adhesive is used, fire resistance and fire resistance are improved.

The composite board of the present invention is used as an exterior material or interior material of a building. As a standard size product supplied to the site, it is 455 × 1820 mm, 455 × 2720.

Some are 30 mm.

[0019]

As described above, the present invention has the following advantages.

In the composite board according to the first aspect of the present invention, the heat insulating board on the back side and the exterior board on the front side are directly bonded by an adhesive at the hole, so that the exterior board is vibrated or the like after construction. Therefore, it does not peel off at the face material and drop.

[0021] The composite board according to the second aspect is characterized in that the isocyanurate foam is used as a foaming material of the heat insulating board, and that the isocyanurate foam itself has high flame resistance and fire resistance due to its flame retardancy. Become.

According to the third aspect of the present invention, since the heat-resistant adhesive is used, the flame-retardant adhesive is not only in the surface material of the bonding surface but also in the hole. Therefore, fire resistance and fire resistance are improved.
