る虞れがあった。According to the above prior art, the outer wall member 2 is tightened by the tightening operation of the tightening bolt 17.
Since the lower back surface 2A of the base metal is pressed against the vertical portion 18B of the base metal 18 to attach the curtain wall to the base metal, the vertical wall portion 18B of the metal base metal 18 directly contacts the outer wall material 2 made of lightweight cellular concrete. , Bolt 17
Since the pressing force due to acts directly on the lower rear surface 2A of the outer wall member 2 from the vertical portion 18B, there is a fear that the outer wall member 2 may be damaged. Since the outer wall material 2 is placed on the horizontal portion 18A of the base metal 18, as shown in FIG. 11, a vertical load F 1 (for example, the curtain wall's own weight) or a lateral load F 2 (for example, wind pressure) that acts on the curtain wall. , Which is a structural material for receiving earthquakes)
Means that these loads are transmitted to the outer wall material 2 as shown by the dotted lines and then supported by the base metal 18, and accordingly, the frame 4 and the outer wall material are point-joined by the bolts 12. Since the load is transmitted at the location, the connection between the frame and the outer wall material is loosened by this load transmission, and as a result, the strength of the entire curtain wall may be reduced.

1C and. As shown in FIG. 7, the receiving member 61 has the base portion 6 in the gap S between the two curtain walls arranged in the lateral direction.
1A and the extension portion 61B are inserted, and the receiving member 61 is attached to the vertical members 5 and 6 of the frame 4 of these two curtain walls with bolts 62 and nuts 63 at the attaching portion 61C. As a result, one receiving member 61 is shared by the two curtain walls, and the receiving member 61 can be reliably inserted even if the gap S is small.

き、カーテンウォールの強度を確保できる。According to the present invention, when the tightening operation of the tightening bolt is performed, the metal receiving member abuts on the vertical portion of the base metal, and the lower rear surface made of lightweight cellular concrete does not directly abut on the vertical portion of the base metal. Therefore, there is no risk of the outer wall material being damaged. Also, since the frame and outer wall material of the curtain wall are placed on the base metal via the receiving material attached to the frame, the load acting on the frame, which is the structural material of the curtain wall, is applied to the base metal via the receiving material. Since the load applied to the frame is not transmitted to the outer wall material and then supported by the base metal, it is possible to prevent the joint between the frame and the outer wall material from slackening and to increase the strength of the curtain wall. Can be secured.
