産業上の利用分野
本考案は木造家屋の外壁における外断熱方式に
採用される外壁構造に関し、さらに詳しくは外断
熱構造において高断熱化を要求される場合の厚張
り壁断熱構造に関する。[Detailed description of the invention] Industrial application field The present invention relates to an external wall structure that is adopted as an external insulation method for the external wall of a wooden house. Regarding insulation structure.
従来の技術
近年、断熱壁構造への関心は居住性向上要求並
びに省エネルギーの必要性と相埃つて一層高まり
つつある。ことに、寒冷地においては高断熱化が
進んでいるが、板状断熱材を壁の外側に設ける外
張り工法は、壁内温度が室内側温度とあまり差が
ないため壁内での結露がなく、家屋の耐久性の点
から好ましい工法として注目されている。BACKGROUND OF THE INVENTION In recent years, interest in heat insulating wall structures has been increasing due to demands for improved livability and the need for energy conservation. In particular, in cold regions, high thermal insulation is progressing, but with the external method of installing plate-shaped insulation materials on the outside of the wall, the temperature inside the wall is not much different from the temperature inside the room, so there is no possibility of condensation inside the wall. It is attracting attention as a preferred construction method from the viewpoint of building durability.
考案が解決しようとする問題点
しかし、一般の断熱材自体は構造上の強度に乏

装材では、中間層に断熱材を有することは外部断
熱構造における泣きどころとされていた。Problems that the invention aims to solve: However, general insulation materials themselves lack structural strength, and extending plate-shaped insulation materials to a thickness of 30 mm or more on the outside of columns requires long attachment nails, which increases the strength of the nails themselves. In addition to the above problems, since an exterior material is required as a protective layer, it has been impossible to obtain a structure that maintains stable adhesion strength in relation to load support of the outer layer. In particular, when finishing with a dry exterior material, the nails become longer because the insulation material does not have the gripping force, and with moisture exterior materials such as mortar, having insulation material in the middle layer is a drawback in the external insulation structure. It was said that
そのため、一般には壁内にグラスウールのごと
き繊維系断熱材を充填補充して省エネルギー、居
住性の向上を図つていた。この工法、すなわち板

層を施す必要があるが、完全な防湿層を施すのは
面倒であり、施工も難しいため完全施工ができ
ず、壁内結露のトラブルが最近多くなつている。 Therefore, in order to save energy and improve livability, the walls were generally filled with fiber-based insulation materials such as glass wool. When using this construction method, that is, a combination of plate insulation material and fiber insulation material, it is necessary to apply a complete moisture barrier layer on the indoor side, that is, the high temperature side, but it is troublesome to apply a complete moisture barrier layer. However, because it is difficult to install, it is not possible to completely install it, and problems with condensation inside walls have been increasing recently.

The purpose of this project is to ensure load-supporting performance, and to provide a highly insulated wall structure that is easy to construct.

く、壁体構造全体が安定した性能を保持する。Function In the thick insulation wall structure as described above, when installing the first layer of plate-shaped insulation material 4, the thickness t1 is selected to be such that it can be fixed by ordinary nailing, and the thickness is pressed from the top surface. Since it is fixed with a crosspiece, the length of the nail used is essentially the same length as the required thickness t of the insulation material, but since the effective length in the wood is long, there is no bending at the anchoring part. The tightening force is also distributed over the entire surface of the presser bar, and there is no fear that the insulation material will be deformed or damaged at the penetrating portion of the insulation material 4, or that the nail heads will come off. In addition, the dead weight of the holding bars, insulation material, and outer layer of the exterior material is all supported by the shaft underlayment by nailing, so there is no structural stress on the insulation material, and the entire wall structure maintains stable performance. Hold.
