Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel used as a structural material on a wall of a building in recent years. The structural material is a member used when a frame is made of wood and a face material such as plywood is hammered to form a wall or the like, and particularly in the case of the present invention, between the face material and the face material. A heat insulating panel sandwiching a foamed heat insulating material is described.

2. Description of the Related Art First, referring to FIG.
Will be described. This heat insulation panel 1 is used in a framed wall construction method which is a construction method in recent years, and is used as a structural material by fastening it to a pillar or a beam with a fastener such as a bolt. It is difficult for the face material 2 used here to be composed of a single plate. Therefore, for the face material 2, plywood called veneer, which is usually prepared by peeling and sticking wood thinly, and in consideration of the environment and resource issues, solidified wood chips are used to solidify the chips produced from solid wood. It is made of chip panels made.
Then, a foamed heat insulating material 3 such as urethane is sandwiched between such face materials 2 to form a heat insulating panel 1.

FIG. 10 shows a wiring method when the outlet box 6 and the switch box 7 are provided on the heat insulation panel 1 of FIG. 9, like the wiring to the switch box 7 shown on the right side of FIG. There is a method in which the electric wire 5 is exposed on the surface of the heat insulating panel 1.

Further, like the wiring to the outlet box 6 shown on the left side of FIG. 10, the face material 2 of the heat insulating panel 1 and the foam heat insulating material 3 are hollowed out to form a space, and the electric wire 5 is placed in the space.
There is a way to do it.

[0005]

In the case of wiring on the heat insulation panel of FIG. 9, in the case of the method shown on the right side of FIG. 10, since the electric wire is exposed on the surface of the heat insulation panel, the heat insulation functioning also as a structural material is achieved. When I used the panel as it was and put a wallpaper on it, it bulged out, impairing my aesthetics.

In the case of the method shown on the left side of FIG. 10, it is necessary to cut the face material of the heat insulating panel, which is troublesome and the face material of the heat insulating panel is cut off. Therefore, the strength as a structural material was weakened.

[0007]

[PROBLEMS TO BE SOLVED BY THE INVENTION] A heat insulation panel in which a foamed heat insulating material is provided on at least one side via a concavo-convex member between face materials, wherein the concavo-convex member and the face material are combined. In this case, the heat insulating panel is characterized in that a space communicating with at least one direction is formed. In addition, it is preferable that the concavo-convex body is made of a soundproof material so that the building has a soundproof effect when used as a structural material such as a wall or a floor.

[0008]

1 to 4 show the structure of a heat insulating panel 1 of the present invention. First, an outline of an embodiment of the present invention will be described with reference to FIGS. The structure of the heat insulating panel 1 will be described in order from the top on the drawing.
・ Consists of foam insulation 3 and face material 2. Face material 2.2
Is made of plywood such as veneer or a chip panel, the foam insulation 3 is made of urethane or the like that has the property of being hardened and adhesive after foam filling, and the concavo-convex body 4 is made of paper, glass fiber non-woven fabric, or the like. It is possible to make it with various materials such as thin metal plates and plastics.

Next, an embodiment of the heat insulating panel 1 will be described with reference to FIG. 3, which is an example in which spaces 1a and 1b are formed vertically and horizontally. As shown in FIGS. 3A, 3B, and 3C, when the heat insulating panel 1 is formed by combining the members described in FIGS. 1 and 2, the vertical direction (when used for a wall,
A space 1a communicating with the vertical direction) and a space 1b communicating with the lateral direction (horizontal direction when used as a wall) are formed. FIG. 3A is a plan view of the heat insulation panel 1, in which the dotted lines represent the vertical and horizontal spaces 1a and 1b, and (B) is the A of (A).
It is an end view when it sees from a direction, and (c) is an end view seen from the B direction of (a).

4A and 4B are shown in FIGS. 3A and 3B.
To make it easier to understand the spaces 1a and 1b shown in (c),
FIG. 2 is a perspective view and a cross-sectional view from another angle of the heat insulating panel 1. At the time of electric wiring, by cutting the face material 2 as in the conventional case, it is possible to perform wiring without damaging the heat insulating panel 1 as a structural material. In particular, if the spaces 1a and 1b are provided in the vertical and horizontal directions as described above, the electric wire 5 can be wired vertically and horizontally.

Next, a method of manufacturing the heat insulation panel 1 will be described. As a first method of forming the foamed heat insulating material 3 via the uneven body 4 between the face material 2 and the face material 2, the manufacturing method shown in FIG. 5 can be considered. In the manufacturing method, as shown in FIG. 5 (a), first, an uneven body 4 provided with unevenness so as to form a groove in the vertical direction when it is used as a wall material is previously bonded to the face material 2. Subsequently, as shown in FIG. 5B, the other surface material 2 and the uneven body 4 are formed.
The foam heat insulating material 3 is foam-filled between them and the face material 2 and the uneven body 4 are fixed to each other.

Next, another method for manufacturing the heat insulating panel 1 will be described. First, a mold 8 as shown in FIG. 6 (a) is prepared, but in order to form the spaces 1a and 1b in the vertical and horizontal directions of the heat insulating panel 1, as shown in this figure, a grid-like shape having bars in the vertical and horizontal directions. The mold 8 of is used. Then, the face material 2 is arranged on one side, and the other side is provided with the concavo-convex body 4 interposed therebetween so that the lattice-shaped surface of the form 8 is on the concavo-convex body 4 side.

At this time, the concavo-convex body 4 is fitted in the mold frame 8. As will be described later, a plastic mold material formed so as to be combined with the mold frame 8 or a folded paper or metal thin plate is considered. To be Further, a mold is applied to the left and right sides via release paper or the like to prepare for foaming. afterwards,
The foamed heat insulating material 3 is foamed and filled between the irregularities 4 and the face material 2. At this time, since the foamed heat insulating material 3 has an adhesive effect, the uneven body 4 and the face material 2 are integrated. In addition, the uneven body 4
Since the foam heat insulating material 3 does not stick to the mold 8 because it is interposed, as shown in FIG. 6B, a panel in which grooves are formed vertically and horizontally by the grid-shaped mold 8 is formed. It's done.

Next, referring to FIGS. 7A and 7B, FIG.
An example of the concavo-convex body 4 forming the heat insulating panel 1 by the manufacturing method described in (b) will be described. 7A and 7B show a mold of the concavo-convex body 4 made of plastic or the like. FIG. 7A is a plan view thereof and FIG. 7B is a perspective view thereof.

When the surface material 2 is further bonded to the uneven body 4 of the panel shown in FIG. 6B thus formed by adhesion or the like, a book in which the spaces 1a and 1b communicate vertically and horizontally (up and down, left and right). It becomes the heat insulation panel 1 of the invention.

When the vertical and horizontal spaces 1a and 1b are formed in this way, as shown in FIG. 4 and FIG. 8B, the electric wires 5 are directed to the vertical and horizontal spaces 1a and 1b toward the outlet box 6 and the like. Since it is sufficient to pass through, it is possible to perform wiring without impairing the strength of the heat insulating panel 1 as a wall which also serves as a structural material. Of course, the spaces 1a and 1b may be communicated only in the vertical direction as shown in FIG.

As described above, a method of foam-filling the foamed heat insulating material 3 such as urethane between the face material 2 and the uneven body 4 is generally used. However, the uneven body 4 is provided on both sides or one side. Foam insulation 3 is foamed and filled, and face materials 2 are applied to both sides later.
-It is also possible to bond 2 together.

Further, an electromagnetic shield such as lead foil may be used for the concavo-convex body 4 of the heat insulation panel 1. Further, if the unevenness 4 is made of a soundproof material such as a lead plate, it becomes a building having a high soundproof effect when used as a structural material such as a wall or floor. The shapes of the spaces 1a and 1b of the heat insulating panel 1 may be such that the foam heat insulating material 3 is firmly foam-filled, and after the filling, the concavo-convex body 4 and the face material 2 are brought into close contact with each other, which is shown in the embodiment of the present invention. In addition to the curved shape, various shapes such as a trapezoid and a semicircle in cross section are possible.

Various sizes of the spaces 1a and 1b and intervals for forming the spaces 1a and 1b can be considered. For example, the width and depth of the spaces 1a and 1b are
The size can be such that the electric wire 5 can be inserted therein, and the switch box 7 and the outlet box 6 can be accommodated therein. Moreover, the space 1a is formed by combining unevennesses of different sizes, the upper space 1a of the heat insulation panel 1 has a wide width, and the lower space 1a has a narrow width or depth. -Various examples are conceivable, such as forming a part of 1b on the heat insulating panel 1.

If the width and the depth of the space 1a are widened so that the outlet box 6 and the switch box 7 can be easily accommodated, the foam insulation material 3 and the concavo-convex body 4 are attached when they are attached to the insulation panel 1. Since only the face material 2 needs to be hollowed out without being hollowed out, the strength can be further maintained.

[0021]

In the case of the conventional wiring method, since the electric wires are exposed on the surface of the heat insulating panel, the heat insulating panel which also serves as the structural material is used as it is, and it sticks out when the wallpaper is pasted, which spoils the appearance. However, since the electric wire can be passed through the space inside the heat insulation panel, it is possible to maintain the aesthetic appearance.

Further, conventionally, the face material of the heat insulating panel has to be cut, which is troublesome, and the face material constituting the heat insulating panel is cut off, so that the strength as a structural material is weakened. However, in the case of the present invention, since the electric wire is passed through the space between the concavo-convex body and the face material, it can be easily attached and the strength as the structural material can be maintained.

Further, if the unevenness 4 is made of a soundproof material such as a lead plate, a building having a high soundproof effect can be obtained when it is used as a structural material such as a wall or a floor.
