[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated wall panel which constitutes a wall of a house such as a house and insulates the wall.

[0002]

2. Description of the Related Art When building a house or the like, it is common to insulate the walls of the house. Insulation of this wall has been performed by using an earth wall in the old days, but in recent general buildings, it has been performed by adopting a structure as shown in FIG. 4, for example.

[0003] That is, by arranging and fixing the inner wall material 12 and the exterior material 11 inside and outside the column 13 as a center,
A wall 10 having a predetermined space between the inner wall material 12 and the exterior material 11 is provided.
Are arranged to insulate the wall 10. The heat insulating material 14 used in this case is made of glass wool or rock wool as a base material.
The heat insulation of the wall 10 is performed by disposing the storage space therebetween. Alternatively, instead of such a simple heat insulating material 14,
As shown in FIG. 5, a single heat-insulating wall panel is formed by wrapping a heat-insulating material 14 made of a foamed synthetic resin molded body with a frame 21, and this heat-insulating wall panel is interposed between the columns 13 of the wall 10. It has also been arranged.

However, in the above-mentioned conventional techniques, there is no operation space for tools when fixing the heat insulating wall panel to a pillar or the like, and no space for wiring or piping in the wall. It is very inconvenient to install.

[0005] Further, the heat insulating material 14 shown in FIG.
Is formed of a gas-permeable material such as glass wool, the cool air from under the floor rises and flows above the ceiling 19 through the heat insulating material 14, so that the inner wall material 12 is cooled. Therefore, in the heat insulating wall panel as shown in FIG. 4, the heat insulating effect is not sufficiently exhibited. When the heat insulating material 14 is made of a material having air permeability such as glass wool, dew condensation may occur in the heat insulating material 14 due to moisture in the room that has entered the heat insulating material 14 through the inner wall material 12. is there. Such dew condensation accumulates and moistens the girth, base, and the like located below, causing the girth, base, and the like to rot and causing the collection of white ants.

For this reason, the inventor of the present invention, for example,
In JP-A-137408, "Insulating wall panels for insulating the walls, which are interposed between the exterior material and the inner wall material constituting the walls and the pillars holding them, A frame fixed to a pillar or the like, a face material fixed to the exterior material side of the frame, and a heat insulating material integrally formed in the face material and the frame to form a predetermined space on the room side; The upper and lower auxiliary insulating portions which are formed integrally with the upper and lower edges of the heat insulating material and completely fill the upper and lower ends of the frame body, and when the heat insulating wall panel is arranged and fixed between the columns, A heat insulating wall panel "characterized in that the gap between the wall, the floor and the ceiling is shielded by each of the auxiliary heat insulating portions, has been already proposed, and almost solves the above-mentioned problem. However, the following new problems have arisen when actually trying to construct this heat insulating wall panel. In other words, the length of the upper auxiliary heat insulating portion that completely fills the upper end of the frame body was sometimes insufficient due to the difference in the ceiling height of the house, and it was found that it lacked versatility. is there.

The inventors of the present invention have conducted intensive research on how to prevent the above-mentioned problems from occurring while having a sufficient heat insulating effect. It was completed.

[0008]

[Problems to be Solved by the Invention] The present invention has been made based on the above-mentioned background, and the problems to be solved are the work on the conventional heat insulation wall panel, the shortage of piping space, the occurrence of dew condensation, and It is not versatile.

A frame 21, a face member 22 fixed to the exterior material 11 side of the frame 21, and heat insulation formed integrally with the face member 22 and the frame 21 to form a predetermined space R on the room side. And upper and lower auxiliary heat insulating portions 24 and 25 formed integrally with the upper and lower ends of the heat insulating material 23 to completely fill the upper and lower ends of the frame 21. Of the lower auxiliary heat insulating portion 25 is twice or more the vertical length of the lower auxiliary heat insulating portion 25, and a ventilation passage 26 for vertically communicating the space R with the upper and lower auxiliary heat insulating portions 24 and 25 is provided. A heat insulating wall panel 20 "characterized by being formed.

[0011]

The heat-insulating wall panel 20 according to the present invention constructed as described above must be arranged and fixed between the columns 13 constituting the house. This is performed using the inner surface of the frame 21 exposed from the heat insulating material 23. That is, in the heat insulating wall panel 20, the frame body 21 is not completely filled with the heat insulating material 23, but the upper and lower auxiliary heat insulating parts 24 and 25.
Since the space R is formed in the intermediate portion where the space is left, the inner surface of the frame 21 corresponding to the space R is exposed. Therefore, by fixing this exposed frame body 21 to the pillar 13 side using a nail or a mounting bracket,
The heat insulating wall panel 20 is arranged and fixed between the columns 13. In this case, not only can the work be performed in the space R that is located on the room side of the frame 21, but also
By utilizing this space R, electrical wiring and outlet boxes, or pipes for water and gas can be provided without any support.

Further, in the heat insulating wall panel 20,
The size of the upper auxiliary heat insulating wall portion 24 is twice the size of the lower auxiliary heat insulating wall portion 25, that is, the size of the lower auxiliary heat insulating wall portion 25.
When the heat insulating wall panel 20 is positioned with respect to the floor surface with reference to the lower auxiliary heat insulating wall portion 25, the ceiling 19 may have any height. Thus, the work can be performed without forming a gap between the ceiling 19. Of course, the lower auxiliary heat insulating wall portion 25 and the upper auxiliary heat insulating wall portion 24 are apparently greatly different from each other. Needless to say, as shown by the line, it is possible to respond sufficiently. Therefore, the heat insulating wall panel 20 is very convenient in construction and has sufficient versatility.

After the heat insulating wall panels 20 have been arranged and fixed between the columns 13 as described above, as shown in FIG. 1
8 and ceiling material 19 are attached. As described above, the ceiling 19 may have any height.
The upper and lower ends of the inner wall material 12 are, as shown in FIG.
5 are in close contact with the side surfaces of the room. Also,
The joist 17 supporting the flooring 18 is also provided at a position in contact with the lower auxiliary heat insulating portion 25 of the heat insulating wall panel 20, and positions the heat insulating wall panel 20 as such.

When the wall 10 as shown in FIG. 1 is completed using the heat insulating wall panel 20 according to the present invention, the lower auxiliary heat insulating portion 25 is provided at the lower end of the heat insulating wall panel 20.
The inflow of the air into the space R is allowed by the ventilation passage 26 of the airbag. At the upper end of the heat insulating wall panel 20, the circulation of the air from the space R to the ceiling 19 side is sufficiently ensured by the ventilation passages 26 formed in the upper and lower auxiliary heat insulating parts 24 and 25. As a result, a stable air layer is secured in the space R, and not only is the heat insulation effect excellent when viewed as a whole wall 10 but also if the space R Even if moisture enters, the moisture is discharged from the ventilation passage 26 to the ceiling 19 side, so that the dew condensation phenomenon due to moisture does not occur in the space R.
