DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall, and more particularly, to a curtain wall formed by using a plurality of different surface materials such as glass, metal panels, and stones.

[0002]

2. Description of the Related Art Conventionally, when an outer wall of a building such as a building is formed of a curtain wall, a portion corresponding to a waist wall or a hanging wall on the building side, that is, a waist portion (spandrel portion) corresponding to a floor slab or the like, In order to make the floor slab invisible in appearance, a non-translucent surface material such as metal or stone is arranged, and a portion corresponding to the opening (vision portion) is provided with a purpose of obtaining lighting. Often, glass face materials are arranged.

[0003] Incidentally, as disclosed in Japanese Patent No. 2515034, a metal or stone face material may be supported by a horizontal material or a vertical material via a seal member in some cases.
Most of them are supported by vertical members and horizontal members using intermediate members such as frame-shaped frames.

[0004]

However, even when a metal or stone face material is supported using an intermediate member,
Glass face materials do not require such intermediate members,
It is still supported on the uprights and crosspieces only via the sealing members. For this reason, as for the vertical and horizontal members, the portions supporting the glass surface material and the portions supporting the metal or stone surface material have different cross-sectional shapes in order to correspond to the presence or absence of the intermediate member. Need to be done. Therefore, there is a problem that the production cost and the management cost are increased, for example, in addition to the types of the vertical members and the horizontal members themselves, the types of the extrusion dies for producing these members are increased.

[0005] An object of the present invention is to secure the cost by sharing the members to which these face members are attached even if there are face members which are attached using the intermediate member and face members which are attached without using the intermediate member. Another object of the present invention is to provide a curtain wall that can be reduced.
