Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is particularly effective for a curtain wall of a type in which face materials such as a plurality of glass plates are attached to the left and right adjacent parts of the glass plates without exposing the frame material to the outside of the room. The present invention relates to a face material mounting portion structure used in.

(Prior Art) Conventionally, as a face material attachment portion structure in a curtain wall of a type in which a plurality of glass plates are attached to the left and right adjacent portions and the vertical adjacent portions thereof without exposing the vertical frame member and the horizontal frame member to the outside of the room, respectively. In a carten wall in which glass is supported by a glass support frame composed of a plurality of vertical frame members and horizontal frame members, a mounting edge frame fixed to the inner surface of the four-circle interior of the glass, the left and right vertical frame members, and the upper and lower horizontal frames. There is known a structure including a glass receiving surface provided on an outdoor side portion of a frame member and a screw-type pulling means for pulling each of the mounting edge frames of the glass to the receiving surface for fastening. However, this conventional structure
Since the glass mounting work is performed from the indoor side, the glass mounting work in the spundle portion is not easy, and the work of replacing the broken glass after assembly is a difficult work requiring skill.

(Problems to be solved by the invention) In this plan, the face material can be attached from the outside of the room to facilitate the work of attaching the face material at the spundle portion and the work of replacing the damaged face material more easily. An object of the present invention is to provide a structure for attaching a face material in a curtain wall which can be used in any of the above.

(Means for solving the problem) Therefore, the present proposal is a curtain wall which is fixed to a building frame and has a face material supported by a grid-like face material support frame composed of a plurality of vertical frame members and horizontal frame members. In the above, the engaging portions are provided on the indoor side surfaces at both left and right ends of the face material, and the left and right vertical frame members are composed of a vertical frame main material and an auxiliary material, and are locked on the outdoor side surfaces of the vertical frame main material. Grooves are formed, and the auxiliary material has a length that is approximately equal to the distance between the horizontal frame members that are vertically adjacent to each other. Is provided with a locking piece, and the upper and lower horizontal frame members have an upper glass fitting groove formed of a receiving portion having an L-shaped cross section and an outer rim having an L-shaped cross section at an upper portion of the outdoor side.
Similarly, a downward glass fitting groove having an L-shaped cross-section receiving portion and an L-shaped cross-section outer rim is formed in the lower part of the outdoor side.
The outer push edges are formed so as to be detachably engaged with the upper and lower horizontal frame members from the outdoor side, respectively. An embodiment of the present invention will be described below with reference to the drawings.
