  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below based on examples of the present invention illustrated in the accompanying drawings.

Figure 1-5 is for indicating the actual施例of the present invention, FIG. 1 is a partial perspective view of a wooden building fitted with such heat insulating wall to the present invention, FIG 2 is a perspective view of the heat insulating wall, FIG. 3 is an enlarged partial sectional view taken along line 3-3 in FIG. 4 is a view taken in the direction of arrow 4 in FIG. 1, and FIG. 5 is a cross-sectional view taken along line 5-5 in FIG.

  First, with reference to FIG.2, 3, the structure of the heat insulation wall for the outside heat insulation of a wooden building is demonstrated.

The heat insulating wall W is composed of a heat insulating wall body 1 and a plurality of synthetic trees 2. The heat insulating wall body 1 is formed into a horizontally long rectangle by a hard foamed synthetic resin material such as polystyrene and polyurethane which has high heat insulating properties and is lightweight. In this embodiment, the vertical width (short side) is The width (long side) of 910 mm is 1,820 mm. And, on the surface (outdoor side) 1A of the heat insulating wall body 1 , a plurality (five) of synthetic trees 2... Are attached in parallel in the horizontal direction with an interval of 410 mm in this embodiment. It is attached by one.

  Each synthetic wood 2 is formed in a long and narrow bar shape having a rectangular cross section by a hard synthetic resin material such as polystyrene, and is formed to have substantially the same length as the vertical width of the heat insulating wall body 1. As described above, the plurality of synthetic trees 2... Are attached to the surface 1A (outdoor side) of the heat insulating wall body 1 integrally in parallel to each other with a gap in the lateral direction. It is the same as the interval between the pillars 10 and the studs 11 of the wooden frame S, and as will be described later, it is easy to attach these composite trees 2 to the pillars 10 and the pillars 11.

  As shown in FIGS. 2 and 3, the surface 2A (outdoor side) of each synthetic tree 2 is formed with a concave groove 3 having a concave cross section over its entire length, and this concave groove 3 is a fixture such as a screw or a nail. It has a depth and width capable of receiving six heads 6H (see FIG. 5). Further, a notch groove 4 having a predetermined depth is formed in the back wall 3A of the recessed groove 3 over the entire length in the center in the width direction. The notch groove 4 is a fixing tool such as a screw or a nail. 6 is used as a guide.

  Below, the construction procedure to the wooden frame S of the heat insulation wall W comprised as mentioned above is demonstrated.

  As shown in FIGS. 1, 4, and 5, the waterproof paper 8 is stretched on the outdoor surface of the wooden frame S standing on the foundation B, and the back surface 1 </ b> B of the heat insulating wall W is stretched on the waterproof paper 8. Next, the heat insulating wall W is fixed to the pillars 10 and the pillars 11 standing on the base 12 through the plurality of synthetic trees 2 with the plurality of screws 6. At this time, the interval between the plurality of composite trees 2... Is equal to the interval between the pillars 10 and the spacers 11 of the wooden frame S. Therefore, it is easy to fix the heat insulating wall W to the wooden frame S with screws 6. Therefore, it is possible to omit the conventional temporary fixing work of the heat insulating material and the work for performing the vertical trunk edge on site. At this time, the screw 6 can use the notch groove 4 formed in the inner wall 6A of the concave groove 3 as a guide, so that the position of the screw 6 can be easily and accurately positioned. Further, in a state in which the heat insulation wall W1 is tightened to the pillar 10 and the intermediate pillar 11 by the screw 6, that is, in a state where the final fastening is completed, the head 6A of the screw 6 is buried in the groove 3 as shown in FIG. Thus, a gap d is formed between the surface 2A of the synthetic tree 2.

After the heat insulation wall W is permanently fixed, the siding 14 is stretched integrally with the surface 2A of the synthetic wood 2. At this time, there is no direct contact between the head 6H of the screw 6 and the back surface of the siding 14, so that a so-called heat bridge phenomenon is avoided and deterioration of the heat insulation performance is prevented. Further, the contact area between the back surface of the siding 14 and the synthetic tree 2 is reduced to protect the back surface of the siding 14. Further, the concave groove 3 of the synthetic wood 2 can form a ventilation groove between the siding 14 and the heat insulating wall body 1 to function as a conventional ventilation trunk edge. In addition, the heat insulating wall W can be provided with a function as a base for attaching the heat insulating wall W to the pillars 10 and 11 .

Having described the actual施例of the present invention, the present invention is not limited to these examples, and various embodiments within the scope of the present invention. For example, in the above-described embodiment, screws are used as the fixing tool, but other equivalents such as nails may be used instead.
