Abstract

<P>PROBLEM TO BE SOLVED: To provide a wall structure which has a high heat insulating effect and high structural strength, and prevents its outer wall member from sagging. <P>SOLUTION: A wall panel 1 is produced by sticking a heat insulator 3 formed of a plastic foam body to the whole of an outer surface of a bearing wall face plate 2, and cutting away predetermined-width sections of the heat insulator 3 along nailing lines to form nailing grooves. The wall panel 1 thus produced is rigidly nailed to wall skeletal columns 51, 52 via the nailing grooves, and spacer members 4 are rigidly fitted into the nailing grooves of the wall panel 1. Each spacer member 4 consists of a spacer main body 41 and a furring strip 42. The main body 41 is the same in width and in thickness as the nailing groove, and made of a material having equal heat insulation performance to that of the heat insulator 3 and having large structural strength. The furring strip 42 is mounted on the outside of the spacer main body 41. In this condition, the furring strip 42 of the spacer member 4 is protruded from the nailing groove formed in the wall panel 1, and then the outer wall member 8 is mounted on the outside of the wall panel and fixed to the furring strips 42 of the respective spacer members 4. <P>COPYRIGHT: (C)2004,JPO

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure using a heat-insulating composite board in a residential heat-insulating structure.
[0002]
[Prior art]
Recently, as shown in FIG. 17, a load-bearing wall material (91) is arranged outside the wall driving pillar (5), and a heat insulating material (92) made of foamed plastic is arranged outside the wall material pillar (5). An outer lining insulation structure is provided in which a torso (93) is arranged at a predetermined position on the outside and fixed with nails (94), and an outer wall material (8) is further arranged outside and fixed to the torso (94). I have.
[0003]
[Problems to be solved by the invention]
In the above-mentioned outer lining heat insulating structure, the heat insulating material (8) is continuously stretched, so that the heat insulating effect is good. The heat insulating material (92) is made of foamed plastic and has a low structural strength. Therefore, when the heat insulating material (92) is thickened, the moment increases and the outer wall material (8) is weighted by the outer wall material (8). There is a problem that it hangs down. Further, in the case of the above-mentioned heat insulating structure, it takes time and effort to fix the load-bearing wall material (91) and the heat insulating material (92) on site.
[0004]
[Means for Solving the Problems]
According to the present invention, as a means for solving the above-mentioned problems, a heat insulating material (3) made of a plastic foam is entirely adhered to the outside of the load-bearing wall material (2), and the heat insulating material (3) is formed along the nailing line NL. 3) is cut to a predetermined width w1, w1 / 2 to form a nailing groove (1A, 1B, 1C) to produce a wall panel (1), and the wall panel (1) is cut into the nailing groove (1A). , 1B, 1C) to the wall driving column (5), and fix it to the nail (1B, 1D) of the wall panel (1) with the width w1 of the nailing groove (1B, 1D). A spacer body (41) made of a material having the same width w2 and thickness t1 as the depth d, having the same heat insulation properties as the heat insulator (3), and having high structural strength, and the outside of the spacer body (41); A spacer member (4) consisting of a torso (42) attached to the In this state, the torso edge (42) of the spacer member (4) projects from the nailing grooves (1B, 1D) of the wall panel (1), and the outer wall material (8) ) Is provided on a wall portion (42) of the spacer member (4).
It is desirable that the thickness of the body edge (42) of the spacer member (4) is set within 20 mm, and the width w3 of the body edge (42) of the spacer member (4) is set to be equal to the wall panel (1). It is preferable that the width is set to be larger than the width w1 of the nailing groove (1B, 1D) by 50 mm or less.
[0005]
[Action / Effect]
In the wall panel (1) of the present invention, since the heat insulating material (3) attached to the outside of the load-bearing wall material (2) is provided with the nailing grooves (1A, 1B, 1C), the load-bearing wall material is provided. (2) can be directly nailed and fixed to the wall driving column (5) through the nailing grooves (1A, 1B, 1C), so that a bearing wall with high strength is formed.
A spacer member (4) is fitted in the nailing grooves (1B, 1D) provided in the heat insulating material (3), and an outer wall material (8) is fixed to the body edge (42) of the spacer member (4). However, since the main body (41) of the spacer member (4) has a heat insulating property substantially equal to that of the heat insulating material (3) and is made of a material having a high structural strength, a heat insulating structure that is continuous vertically and horizontally is formed. Since there is no portion and the outer wall material (8) is fixed to the driving column (5) via the spacer member (4) without the use of heat insulating material, the hanging of the outer wall material (8) is reliably prevented. Is done.
[0006]
Further, since the body edge (42) of the spacer member (4) protrudes (from the outer surface) from the heat insulating material (3) of the wall panel (1), the space between the outer wall material (8) and the wall panel (1) is formed. A gap (within 20 mm) is formed, a ventilation layer is formed by the gap, and if this ventilation layer is released to the outside (for example, from the lower wall portion), air is exchanged between the outside and the air layer, Moisture does not accumulate in the walls, preventing condensation.
In addition, since the load-bearing wall material (2) and the heat insulating material (3) are attached in advance, the process can be shortened, and double labor of attaching the load-bearing wall material and the heat insulating material on site can be eliminated.
