ある。[Detailed description of the invention] The present invention relates to a waterproofing device for a curtain wall in which equal pressure chambers are provided in mullions and on the open side and communicate with the outside world through outside air introduction holes. A shielding plate that partially partitions the blind side isobaric chamber is provided at the middle part of the end of the isobaric chamber in the indoor and outdoor direction, and a mullion side isobaric chamber is provided above the indoor side of this shielding plate. In addition, the outside air introduction hole is provided in the open space at a position on the outdoor side of the shielding plate and overlapping the shielding plate.

構成するのである。 The drawing shows an embodiment of the waterproofing device for a curtain wall according to the present invention, where A is open and A is open.
First and second receiving pieces 1a, 1 provided on the indoor side of
b, each of the first and second locking pieces 2a provided on the ridge 3;
2b is locked and the ridge 3 is attached to the blind A, and the first equal pressure chamber 4 composed of the blind A and the ridge 3 is attached to a part of the first receiving piece 1a near the mullion B. The second isobaric chamber 6 is placed directly under a panel 7 such as a glass plate, and a part of the second locking piece 2b is cut out. It communicates with the first isobaric chamber 4 through a pressure adjustment hole 8 provided therein, and communicates with a third isobaric chamber 10 constituted by a ridge 9 fixed to the mullion B, so that each of the isobaric chambers 4,
6 and 10 form a so-called isobaric structure, and a shielding plate 11 that partially partitions the isobaric chamber 6 is attached to the middle part of the end of the second isobaric chamber 6 in the indoor/outdoor direction with screws 12. The above-mentioned outside air introduction hole 5 is provided in the closed area A at a position on the outdoor side of this shielding plate 11 and overlaps with the shielding plate 11.
The third isobaric chamber 10 is arranged above the indoor side of the chamber.

る。 Since the present invention has the above-mentioned configuration, the wind that enters through the outside air intake hole collides with the shielding plate and circulates inside the isobaric chamber. Invading water is prevented from entering the indoor side as much as possible, and even if water intrudes into the mullion, the wind force is weakened by the shielding plate, so the intruding water will blow up inside the mullion. Drainage can be carried out smoothly without water leaking, and therefore it is suitable as a waterproofing device for curtain walls.
