Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall in which exterior panels are arranged vertically and horizontally on the outer wall side of a building.

[0002]

2. Description of the Related Art The above curtain wall is widely used for new construction, for example, for covering the exterior wall surface of a concrete exposed structure, and for refurbishment for covering the obsolete or damaged exterior wall surface of an existing building. It is used, and an exterior panel in which a reinforcing frame is provided on a peripheral portion of a plate-shaped panel member is stretched on the outer wall side of a building in a row in the vertical direction and the horizontal direction.

In such a structure, in order to stretch the exterior panel on the panel support structure on the body side, conventionally, for example, as shown in Japanese Utility Model Publication No. 4-49316, an appropriate panel holding member is used. The exterior panels, which are continuous in the vertical direction, are fixedly held together by joint fastening at joints between the panels. Thus, if the panel holding member is commonly used for fixing and holding the upper and lower panels, it is believed that the required number of panel holding members is reduced and the fixing work is simplified.

[0004]

However, fixing and holding a panel between narrow joints not only requires unexpectedly difficult and difficult work, but also increases the number of members that make up the panel holding member, rather fixing it. It was troublesome to work. In addition, although the panel itself is divided into small pieces, it still has a considerable weight, and when holding the panels of this heavy object in place with the upper and lower panels fixed at once, It was absolutely necessary to have a special holding means, or there was a risk of winning when relying on manpower.

The present invention is a rational improvement that abandons the idea that the panel must be fixed by some means, and conversely makes good use of the fact that the exterior panel is relatively heavy even by itself. The technology makes it possible to eliminate the need for detailed panel fixing means and its fixing work, simplify the panel tensioning work and improve workability, and provide a curtain wall that can significantly shorten the construction period. Is intended.
