Abstract

An exterior wall (W) formed by joining exterior wall panels (A) to both sides of steel beam columns (B). Each exterior wall panel (A) has a heat insulating board (30) as an exterior heat insulating material bonded to a panel frame (10) on its surface on the exterior side, and also has ventilation furring strips (40) fixed to the heat insulating board (30) on its surface on the exterior side. The ventilation furring strips (40) provide a ventilation layer (41) between an exterior wall surface material (50) and the heat insulating board (30). A joint of the heat insulating board (30) is located on a steel beam column (B) on its exterior side. A heat insulating material (31) for the joint is applied to the steel beam column (B) on its exterior side, and this prevents the joint from functioning as a heat bridge. Because of the presence of the ventilation layer (41), moisture entering from the outside can be efficiently discharged. Dew condensation is less likely to occur on the surface of a structure body and as a result the durability of the structure body is enhanced.

Description

technical field [0001] The present invention relates to external walls forming part of the walls of externally insulated structures. Background technique [0002] In recent years, in general houses and the like, buildings in which the main structure is composed of steel beams and columns are often constructed from the viewpoint of good constructability and earthquake resistance. In addition, in buildings with a steel beam-column structure, the exterior wall is constructed by attaching the initially panelized exterior wall to steel beams and columns, thereby reducing the man-hours for on-site construction and shortening the construction period. [0003] On the other hand, in this kind of building, due to the good thermal conductivity of the main body of the steel beam-column structure, it is easy to generate internal dew condensation in the wall, and the heat insulation method, waterproof method and ventilation method will greatly affect the durability of the building. sex. ...
