Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating material, and more particularly to a heat insulating material and a heat insulating structure provided between base materials.

[0002]

2. Description of the Related Art Conventionally, a heat insulating material for a building is installed between base materials such as an interior. However, when outside air or the like flows between the heat insulating material and the indoor side material, there is a problem that the heat insulating performance is not sufficiently exhibited. Therefore, a construction method for filling a gap between the indoor side material and the heat insulating material, for example, as shown in FIG. 6, a notch 73 is provided at the end of the plate-like heat insulating material 7 as shown in FIG. The method shown in Japanese Patent Application Laid-Open No. 07-317170, in which the heat insulating material end 72 is folded back, is employed.

[0003]

However, as shown in FIG. 3, in the case of the method disclosed in Japanese Patent Application Laid-Open No. 10-292519, in which Since a plurality of receiving objects 6 are used for one piece of material, much labor is required for installation. Further, the thickness of the metal receiving member 6 tends to cause irregularities in the face material 3, causing the floor to squeak when walking and causing discomfort to the resident.

Further, as shown in FIG. 4, in the case of the method shown in Japanese Patent Application Laid-Open No. 07-317170 in which a notch 73 is provided at the end of the plate-like heat insulating material 7 and the rectangular heat insulating material end 72 is folded back for construction. Since the thickness of the heat insulating material end 72 in the rectangular shape matches the thickness of the heat insulating material 7, there is no freedom in height adjustment. To change the thickness of the heat insulating material end 72 in order to adjust the height, cut horizontally. This requires an additional step, which causes a problem that processing time is required. In addition, the rectangular heat insulating material end portion 72 supports the plate heat insulating material 7 on the surface, and if the height adjustment is not appropriate, the repulsive force is large and the surface material 3 becomes uneven, and the method shown in FIG. A similar problem will occur. An object of the present invention is to solve the above problems.

[0005]

SUMMARY OF THE INVENTION The present invention is as follows. (1) A heat insulating material, which is a molded article of a foamed plastic heat insulating material, wherein a heat insulating material main body 11 and a triangular prism-shaped heat insulating material end 12 are connected via a cut 13.

Insulation material characterized by being used.

(3) The heat insulating material according to (2), wherein a predetermined thickness B can be easily obtained by changing the angle A of the triangular prism-shaped heat insulating material end portion 12. (4) The vertex 14 located on the rearmost surface side of the heat insulating material according to (2), in which the triangular prism-shaped heat insulating material end portion 12 is folded back at the cut 13, is easily compressed and deformed, and thus is located on the heat insulating material 1 upper surface. A heat insulating structure, wherein a gap between the face material 3 and the heat insulating material 1 is filled.

BEST MODE FOR CARRYING OUT THE INVENTION

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on embodiments shown in the drawings. FIG. 1 is a cross-sectional view of an end of a heat insulating material of the present invention, FIGS. 2A and 2B show an embodiment of a floor on which the heat insulating material of the present invention is applied, and FIG. 2B is a heat insulating material. FIG. 2 (A) is a side sectional view showing an example of a case in which is applied to the back surface of a floor base material.
FIG. 3 is a sectional view taken along line AA of FIG.

In the embodiment shown in FIGS. 1 and 2, the heat insulating material of the present invention is made of a wooden house floor, more specifically, a floor material 3 and a bar-shaped floor base material 2 for supporting the floor material 3, and a right angle thereto. This is an example of a case where the present invention is used for a floor composed of support members 4 of floor base materials 2 arranged in different directions. The heat insulating material 1 of the present invention is installed between the bar-shaped floor base materials 2 in a state in which the triangular prism-shaped heat insulating material end 12 is folded from the cut 13 portion to the back surface of the heat insulating material main body 11.
This heat insulating material is a heat insulating material of a foamed plastic type, specifically, a foamed polyethylene, a foamed phenol, a foamed polystyrene, a foamed urethane, and a foamed polypropylene. At this time, the heat insulating material 1 is installed so that the apex 14 of the triangular prism-shaped heat insulating material end 12 located at the rearmost side is positioned on the support member 4 of the floor base material 2.

The angle A of the triangular prismatic heat insulating material end 12 is determined by considering at least the thickness B of the triangular prismatic heat insulating material end 12 and the thickness of the heat insulating material 1 in consideration of the height of the floor base material 2 and the thickness of the heat insulating material 1. Is determined to be greater than or equal to the height of the flooring material 2, preferably about 2 mm to 5 mm higher than the height of the flooring material 2. Next, when the floor surface material 3 is installed on the upper surface of the heat insulating material 1, the apex portion of the triangular prism-shaped heat insulating material end portion 12 is compressed and deformed, and the heat insulating material 1 and the floor surface material 3 come into close contact with each other. This triangular prism-shaped heat insulating material end 1
Since the top area 14 of the second member 14 has a small supporting area, is easily compressed and deformed, and has a small repulsive force, the floor surface material 3 is less likely to be uneven.

[0011]

The present invention has the above configuration and has the following effects. Insulation can be adhered to the interior side material without the need for construction work. The height can be easily adjusted, and it can correspond to various base materials. The compression rebound is small, and the surface material is unlikely to be uneven.
