Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of a warp or a torsion by providing a plate-like face material on one face of a foam plastic layer, and applying notches to the foam plastic layer in the vertical direction to its face. SOLUTION: Only a foam plastic is laminated on a plate-like face material made of structural plywood 6 without using a frame material, and fine V-shaped notches 8 are provided on this foam plastic layer 7 in the vertical and horizontal directions. The surface of the foam plastic layer 7 is covered with a face material such as paper or a film. The strong adhesive force primarily provided in a resin is utilized, and the foam plastic layer 7 can be integrally stuck to the plate-like face material 6 concurrently with foaming in one process. When a deformation, particularly contraction stress, is applied to the foam plastic layer 7, the gap intervals of the notches 8 are spread to absorb the stress, and neither a warp nor a torsion occurs on this heat insulating panel.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a heat-insulating panel used for a roof, a wall, a floor and the like of a building such as a house.

[0002]

2. Description of the Related Art Conventionally, heat insulating panels in which a plate-like face material such as structural plywood and a foamed plastic heat insulating material are integrated have been used for roofs, walls, floors and the like of buildings. These heat insulation panels are formed by attaching a separately molded foam plastic board to one side of the structural plywood with an adhesive, or joining a wooden frame to one side of the structural plywood to form a cubic space composed of plywood and a frame material. Then, a resin as a raw material of foamed plastic was sprayed or laminated by a method such as injection.

[0003]

However, in a method of bonding a separately molded foam plastic board with an adhesive, the production cost is increased since two steps are required.
In addition, in the above methods of spraying and pouring, since a thick wooden frame material is used, the manufacturing cost increases, the weight becomes heavy and handling becomes inconvenient, and the frame material becomes a thermal bridge and the heat insulation performance is reduced. There were problems such as falling.

[0004] Only foamed plastic is laminated on a plate-like face material such as a structural plywood without using a frame material, and the other face of the foamed plastic layer is exposed or a thin face material such as paper is stuck. Although it is most preferable to use only the structure, in this case, there is a problem that the panel is warped or twisted due to deformation, particularly shrinkage, of the foamed plastic layer.

The problem to be solved by the present invention is that only foamed plastic is laminated on a plate-like face material such as structural plywood without using a frame material, and the other face of the foamed plastic layer is exposed. In other words, what kind of measures should be taken to prevent the panel from being warped or twisted by simply attaching a thin surface material such as paper.

[0006]

In order to solve such a problem, according to the present invention, a plate-like face material such as a structural plywood is provided.
In the panel in which the foamed plastic was laminated, a cutout was made in the foamed plastic layer in a direction perpendicular to the surface thereof.

[0007]

With the structure described above, even when deformation, especially shrinkage stress, acts on the foamed plastic layer, the stress is absorbed by expanding the gaps between the cuts. Does not warp or twist.

Embodiments will be described with reference to the drawings.
FIG. 1 is an explanatory diagram showing an example of use of the heat insulating panel according to the present invention for an outer peripheral wall. 1 is a cloth foundation, 2 is a base, 3 is a pillar, and 4 is a trunk difference, and a heat insulating panel 5 is in a state of being nailed to a pillar and a horizontal member.

FIG. 2 is a horizontal sectional view of an example of use for the outer peripheral wall, where 9 is a stud and 10 is an interior base material such as a gypsum board. 11 is a moisture-permeable waterproof sheet, 12 is a rim, and 13 is an outer wall material. Numeral 8 is a cut formed in the foamed plastic layer. The surface portion of the foamed plastic layer slightly spreads due to the contraction of the foamed plastic layer, and has a thin V-shaped cross section.

FIG. 3 shows one embodiment of the heat insulating panel structure according to the present invention.
It is explanatory drawing which shows an Example, 6 is a structural plywood, 7 is a foamed plastic layer, and the foamed plastic layer is provided with the notch 8 in the longitudinal and horizontal directions. Reference numeral 17 denotes a face material such as a paper or a film covering the surface of the foamed plastic layer, which is desirably continuous, but may be cut along the cuts, and is not necessarily used.

FIG. 4 is an explanatory view showing the cross-sectional shape in the width direction of the heat insulating panel structure according to the present invention. The cut 8 has a thin V-shape due to the contraction of the foamed plastic layer.

FIG. 5 is an explanatory view of a heat insulating panel structure according to the prior art, in which 14 is a structural plywood, 15 is a frame material, and 16 is a foamed plastic layer.

[0013]

Since the present invention is configured as described above, it has the following effects.

By utilizing the inherent strong adhesive force of the resin, the foamed plastic layer can be adhered to the plate-like face material at the same time as foaming in one step and integrated, so that the production cost can be reduced. . Further, since a thick wooden frame material is not used, it is light and easy to handle, and since there is no thermal bridge, it is possible to provide an insulated panel which is excellent in heat insulating properties and inexpensive.
