BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating material retainer for forming a heat insulating wall body, which is used for surely adhering a heat insulating material housed in a wall body to an inner wall.

[0002]

2. Description of the Related Art As shown in FIG. 10, in order to improve the heat insulation of the wall of a house,
Insulation material a made of glass wool wrapped in a moisture-proof sheet
Is installed between the inner wall b and the outer wall c.

In order for this heat insulating material to exhibit an efficient heat insulating action, it is necessary to ensure that the inner surface portion d is in close contact with the inner wall b. Could not be secured.

That is, the heat insulation material in which glass wool is enclosed is in a fluffy state, and the thickness thereof is smaller than the front and rear width of the space in the wall body, and the heat insulation material is provided in the space between the columns. Since the work of installing the heat insulator had to be performed from the inside of the room after forming the outer wall, the heat insulating material tended to escape to the outside during the installation. Once the insulation escapes to the outside, it can no longer be pulled back inwards, so the insulation a
6 is partially in the depressed state e as shown in FIG. As a result, the adhesion between the outer surface portion f of the inner wall and the inner surface portion g of the heat insulating material becomes poor.

When the poor adhesion occurs in this way, there is a problem that the heat insulating effect of the wall body is impaired. In addition, the fact that the heat insulating material is partially collapsed means that when the air passage is planned to be formed between the heat insulating material and the outer wall, the air passage h is partially closed as shown in FIG. There was a problem that this resulted in deterioration of air permeability in the wall.

The applicant of the present invention has proposed a pressing member capable of solving such a problem in Japanese Utility Model Laid-Open No. 22711/1990. As shown in FIG. 11, the pressing member j is formed by projecting a pressing piece n of a heat insulating material at an outer end of a mounting piece m attached to a side surface k of the pillar. The attachment pieces m are tacked or nailed and fixed to the left and right side surfaces k and k, respectively.

Therefore, in forming the heat insulating wall body, it is necessary to individually position a considerable number of the pressing members and fix them to the side surface of the column, which requires a lot of labor and has a problem of poor work efficiency. It was

According to the present invention, a heat insulating material pressing tool for forming a heat insulating wall body can be formed in which the heat insulating material housed in the wall body can be surely brought into close contact with the inner wall and the workability of the heat insulating wall body can be improved. The purpose is to provide a presser foot).

[0009]

In order to solve the above problems, the present invention employs the following means. That is, the presser foot 1 according to the present invention has the inner wall 25 formed inside and outside the column.
A heat insulating material retainer used for forming a heat insulating wall body in which the heat insulating material 9 is housed between the outer wall 17 and the outer wall 17,
A pair of opposing holding pieces 2 and 2 are connected to each other by a connecting piece 3 to form a tapered U-shape.
The part 5 on the inner side of the pillar is elastically held between the two, and the connecting piece 3 is provided with a holding part 7 capable of contacting the inner surface 6 of the pillar. The portion (the tip or a portion near the tip) is characterized in that pressing pieces 11, 11 for pressing the heat insulating material stored in the space between the pillars against the inner wall 25 are formed in a protruding manner in the opposite direction. .

[0010]

When the presser foot 1 is attached to the pillar, the opening of the holding portion 7 is applied to the inner end portion of the vertical required portion of the pillar 4 and then the holding portion 7 is pushed outward. The inner portion 5 of the pillar 4 is fitted into the holding portion 7. This allows
Since the holding part 7 has a U-shape with a narrowed tip, the pillar is elastically held between the two holding pieces 2 and 2, the connecting piece 3 abuts on the inner surface 6 of the pillar, and both holding pieces are held. 11 and 11 are projected toward the other adjacent column, and both pressing pieces are stably held by the column while being positioned as required.

In this holding state, for example, when the holding piece 2 is tackered or nailed to the side surface of the pillar, the holding tool 1 is fixed to the pillar, and both holding pieces 11 and 11 are set in the space between the pillars. The heat insulating material 9 is pressed against the inner wall 25 so that the heat insulating material inner surface portion 4
0 is brought into close contact with the outer surface portion 41 of the inner wall.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is possible to make sure that the heat insulating material housed in the wall body can be firmly adhered to the inner wall, and also to improve the workability of the heat insulating wall body. . More specifically,

Since the holding member according to the present invention is formed by projecting the holding pieces in opposite directions to the holding pieces facing each other of the holding portion having a U-shape with a narrowed tip, the holding piece can be held at a required position in the vertical direction of the column. When the column is fitted into the portion, both pressing pieces are positioned as required and are stably held by the column. Therefore, if the holding part is fixed to the pillar by tucking, etc.,
Both holding pieces will be correctly positioned and fixed to the column at the same time. For this reason, compared to the conventional construction in which the pressing members are individually positioned and fixed to the left and right side surfaces of the column, the labor required for the fixing can be reduced and workability can be improved.

Further, the retainer fixed to the pillar improves the heat insulating property of the wall body by keeping the heat insulating material in close contact with the inner wall. In addition, a clear ventilation space that communicates vertically is formed between the heat insulating material and the outer wall to improve the air permeability inside the wall body.
