Further, in the vertical case, raindrops having kinetic energy may sometimes jump into the hollow front part (18) from the outside air introduction hole (48), but such raindrops may be formed on the inner wall surface of the hollow front part (18). The trapped raindrops are prevented from entering the primary space (A ₁ ), and the trapped raindrops flow down in the hollow front portion (18) and are discharged by a usual means. On the horizontal side, when raindrops with kinetic energy drain into the primary space (B ₁ ) from the drainage / outside air introduction hole, such raindrops are prevented from entering by the rising edge (10) and drained again. It is discharged from the outside air introduction hole.

In addition, in the connecting portion between the cross member (2) and the cuboid (1), if necessary, as shown by the chain line in FIG. It is advisable to install a water tray (55) whose bottom plate is bent in two steps along the outdoor side surface of the rising edge (10) and the upper surface of the upper edge frame (4).

Another embodiment shown in FIG. 4 is the upper, lower, left and right edge frames of the glass plate (3a).
Each of the bases (4a) and (5a) (the left and right edge frames are not shown) has an L-shaped cross section, and the other structures are substantially the same as the first example.

In another embodiment of FIG. 5, the bases of the upper and lower sides of the glass plate (3b), the left and right edge frames (4b), (5b) (the left and right vertical frames are not shown) are flat plates, and the other structure is This is an example substantially the same as the first example.

(Effects of the Invention) According to the isobaric watertight structure of the curtain wall of the present invention, since the hollow hollow front part is used and the isobaric passage is used to form the isobaric space communicating with the outside air, the isobaric structure is improved. This is extremely simple, and it is possible to open the outside air introduction hole sufficiently wide, whereby an effective isobaric action can be exerted and sufficient water tightness can be maintained.
