うものであつた。 BACKGROUND ART Conventionally, for indoor and outdoor insulation of buildings, etc., an external insulation structure has been used in which a heat insulating material is provided on the outdoor side of a frame such as concrete. That is, as shown in FIG. 1, a heat insulating material 12 made of polymer foam or the like is fixedly provided between a concrete frame 10 and a finishing layer 11 of glass fiber or the like to insulate the interior and exterior. Ta.

てしまうなどという問題があつた。 However, in the structure described above, when the finishing layer 11 expands and contracts due to outdoor temperature changes, etc., a difference occurs between the expansion and contraction of the concrete frame 10 on the indoor side, and the concrete body 10 expands and contracts.
The heat insulating material 12 fixed to restrains the movement of the finishing layer 11. Therefore, there have been problems such as cracks occurring in the finishing layer 11 and separation of the finishing layer 11 and the heat insulating material 12.

造である。 The present invention aims to solve the above-mentioned problems by attaching a polymeric foam insulation material to the outdoor side of the concrete frame of an exterior wall, adhering a finishing layer to the outside of the insulation material, and attaching the insulation material to the concrete side. The insulation material and the finishing layer side insulation material are separated and formed into two layers and placed opposite each other, and the foaming ratio of the finishing layer side insulation material is made larger than the foaming ratio of the concrete side insulation material. This is an external insulation structure for the outer wall of a building.
次に、図面に示す実施態様について説明する。 Next, embodiments shown in the drawings will be described.

ある。 Figure 2 shows a cross-sectional view of a part of the outer wall of the building, with A and B showing the indoor side and the outdoor side, respectively.
A is concrete for the building frame, B is a heat insulating material made of polymer foam, and C is a finishing layer filled with glass fiber mesh 3 to prevent damage such as cracks.

材B1，B2が剥離しないように接面６に熱融着処
理を施して接着する。 The insulation material B is thick concrete side insulation material B 1
and the thin finishing layer side insulation material B 2 are separately formed and placed opposite each other, but the thick concrete side insulation material B 1 has the same foaming ratio as before, and the thin finishing layer side insulation material B 2 is the same as the concrete side insulation material B. The foaming ratio is increased so that the elasticity is greater than that of the first insulation material B 1 and B 2 , and the contact surface 6 is subjected to a heat-sealing treatment to be bonded so that the two insulation materials B 1 and B 2 do not separate.

れず、ひび割れなどが発生しない。 As described above, in the present invention, the foaming ratio of the concrete side insulation material B 1 is higher than that of the concrete side insulation material B 1 .
The foaming ratio of the heat-sealed finishing layer side insulation material B2 is high and the elasticity is also high. Therefore, even if the heat insulating material B2 undergoes movement due to a temperature change in the finishing layer 3, it expands and contracts more than the heat insulating material B1 , and the heat insulating material
Since it expands and contracts freely independently of B 1 , it is possible to prevent the movement of the finishing layer 3 from being directly transmitted to the building frame, and the movement of the finishing layer 3 due to temperature changes is not restricted and cracks do not occur.
なお、両断熱材B1，B2はセツトとしてあらか

The finishing layer C is applied after the formwork is demolded.

実施できるという効果を奏する。 In this way, the present invention increases the foaming ratio of the insulation material on the finishing layer side compared to the foaming ratio of the insulation material on the concrete side to cut off the movement of the building frame and the movement of the finishing layer, and prevents the finishing layer from changing due to the effects of temperature changes, etc. Since the movement of the layers is not restricted, cracks do not occur in the finish layer, the finish layer and the insulation material do not separate, the cost is low, and the construction is easy and can be carried out suitably. play.
