HEAT INSULATING WALL STRUCTURE

To provide a heat insulating wall structure which has a wall material layer formed of a wall panel fitted to a skeleton by a rocking construction method and a heat insulating layer, which is formed by laminating multiple heat insulating layers in the thickness direction, and which suppresses peeling and damage of the heat insulating plates, when fluctuation or displacement of the heat insulating plates occurs due to vibration of the skeleton, by preventing movement of humidity and moisture from one side of the wall to the other side.SOLUTION: A first heat insulating laminate 21 is formed by laminating, in a thickness direction, heat insulating plates 21a, 21b with different length in the width direction of a wall panel 11. The heat insulating plate 21a of the wall panel 11 side is bonded to the wall panel 11. In a gap between the adjacent two first heat insulating laminates 21, 21, a second heat insulating laminate 22 formed by laminating, in a thickness direction, heat insulating plates 22a, 22b with different length in the width direction of the wall panel 11 is non-bondedly engaged with the first heat insulating laminate 21 and the wall panel 11 to form a heat insulating layer 20.SELECTED DRAWING: Figure 1 【課題】ロッキング構法で躯体に取り付けられた壁パネルからなる壁材層と、断熱層と、を有し、断熱層が断熱パネルを厚さ方向に複数枚積層してなる断熱壁構造において、壁の一方から他方への湿気や水分の移動を防止した上で、躯体の揺れに起因して壁パネルに揺動又は変位が発生した際の、断熱板の剥離や損傷を抑制する。【解決手段】壁パネル１１の幅方向において長さの異なる断熱板２１ａ，２１ｂを厚さ方向に積層してなる第１の断熱積層体２１の、壁パネル１１側の断熱板２１ａを壁パネル１１に接着し、隣り合う２枚の第１の断熱積層体２１，２１間の間隙に、壁パネル１１の幅方向において長さの異なる断熱板２２ａ，２２ｂを厚さ方向に積層してなる第２の断熱積層体２２を、第１の断熱積層体２１及び壁パネル１１に対して非接着で嵌合した断熱層２０を構成する。【選択図】図１
