Description

[Detailed explanation of the idea] This proposal concerns the improvement of construction panels.

Generally, this type of panel is lightweight and has structural strength,
It is also desirable to have heat insulating properties.

As a conventional panel of this kind, one in which face plates are attached to the front and back surfaces of a honeycomb-structured core material having a large number of voids is known.

However, although this panel has structural strength, it has the disadvantage of poor insulation performance.

The present invention has been developed in view of the above-mentioned problems and provides a composite panel for construction that solves the above-mentioned drawbacks.

Next, an embodiment of the present invention will be described with reference to the drawings.

The composite panel of the present invention has a honeycomb structure, and the wall body 2' constitutes a large number of parallel cavities.

2'... are arranged in a direction perpendicular to the panel surface, and a core material 1 consisting of a heat insulating material 3 of a predetermined thickness such as phenol resin or foamed polyurethane is covered with copper plates, aluminum plates, etc. It is constructed by attaching face plates 4, 4 made of metal, and at this time, the thickness of the reinforcing member 2 is set to be less than the distance between the double-sided plates 4, 4.

As shown in FIG. 2, the core material 1 has a structure in which the end portions W of the walls are embedded in one surface of the reinforcing member 2 and are combined together, or as shown in FIG. A structure in which the ends of both sides are embedded in the heat insulating material 13, 13, respectively, or a structure in which the ends of the reinforcing members 22, 22 are embedded in the ends of both sides of the heat insulating material 23, as shown in FIG. 4, are considered. It will be done.

In this way, the reinforcing members 2, 12.22 are connected to the heat insulating materials 3, 13.
．． By embedding the core material 1 in the insulation material 3.23, the core material 1 becomes a strong and integral body, and moreover, the external force applied to the reinforcing member 2. 13. 23 can be absorbed, it is possible to prevent damage to the reinforcing members 2, 12, 22, and improve structural strength.

In each of the embodiments described above, the thickness of the reinforcing member 2, 12.22 is made smaller than the distance between the double-sided plates 4.4, as in the first embodiment.

In addition, in forming the core material 1, if the heat insulating material 3, 13.23 is made of polyurethane, polyurethane is sprayed onto the reinforcing member 2, 12.22 to form the heat insulating material 3, 13.23. If the insulation material 3, 13.23 is made of phenolic resin, powdered phenolic resin is sprinkled in the mold and the reinforcing member 2 is placed on top of the phenolic resin.
By placing ゜12.22 and heating it, the phenol resin can be foamed and the two can be integrated.

The proposed panel constructed as described above is lightweight, has high heat insulation properties, has structural strength, and even when an impact external force is applied to the face plate, the heat insulation material made of synthetic resin foam remains intact. It absorbs impact force and prevents damage to the reinforcing member, and since the reinforcing member does not span between the face plates 4 and 4, and a heat insulating material made of synthetic resin foam is interposed in between, the material of the reinforcing member is a heat insulating material. Free materials such as metal materials can also be used since they do not affect performance.

Therefore, compared to conventional products, the present invention has the advantage that it can be used for extremely common applications such as exterior walls, roofs, partitions, and floors of buildings.
