Next, referring to FIGS. 2, 4 and 5,
The rain action at the junction between the units 3 and 3 adjacent on the left and right will be described. The joint between the units 3 and 3 adjacent on the left and right has a clearance for escape in consideration of thermal expansion of the unit 3 and the like. Therefore, in this portion, the rain seal 61, the air seal 62, and the like become discontinuous (see FIG. 4). Therefore, a short water-sealing joint 21 and a rain-prevention plate 22 are provided so as to extend over both units 3 and 3 in this portion. The water sealing joint 21 is made of a sealing material such as silicon foam rubber having a cross-sectional shape that matches the cross-sectional shape of the equal-pressure groove 53 of the upper frame 8 that forms the equal-pressure space 18.

The rain shield 22 is made of a metal plate such as an aluminum plate having a sectional shape conforming to the indoor wall surface of the rain gutter 51 of the upper frame 8, and is screwed to one of the adjacent units 3. . This prevents rainwater from directly hitting the water sealing joint 21, thereby preventing rainwater from entering from between the water sealing joint 21 and the equal pressure groove 53 due to surface tension.

As described above, the water sealing joint 21 and the rain shield 22 ensure that the joints of the adjacent units 3 and 3 are properly rained. Therefore, as shown in FIG.
At the intersection of the units 3 and 3, for example, rainwater enters the equal pressure space 17 of the vertical frames 7 and 7 of the upper units 3 and 3 under bad conditions, and the upper part of the water sealing joint 21 of the lower units 3 and 3. Rain water flows from the upper side of the water sealing joint 21 to the rain gutter section 51 from the drain hole 63 through the equal pressure grooves 18 of the lower units 3.

As described above, according to the present embodiment, the unit frame 5 projects substantially flush with the glass 6 on the indoor side and projects on the outdoor side in the expected direction.
The interior side becomes a neat fit, and the design of the inner wall surface on the indoor side such as a stairwell can be improved. The outdoor side can also be positively incorporated into the design as a grid-like outer wall. In addition, since the unit frame 5 is configured such that the half on the outdoor side is the rain gutter part 51 and the half on the indoor side constitutes the equal pressure space 18, the intrusion of rainwater can be prevented in a stepwise manner. It is possible to ensure the finish, and the water seal joint 21 can also ensure the rain at the joint between the units 3 and 3.

In the present embodiment, the case where the present invention is applied to a unit type curtain wall has been described. However, the present invention is not limited to this, and it goes without saying that the present invention can be applied to various curtain walls. Further, the water sealing engagement portion does not need to be of a type constituting an equal pressure space.

[0027]

As described above, according to the first aspect of the present invention,
Since the finding surfaces on the indoor side of the panel body and the unit frame are made substantially flush with each other, the inner wall surface can be made clearer, and the design of the inner wall surface can be improved. In addition, in the water sealing which is a weak point at that time, the water sealing engagement portion is formed in the indoor half of the unit frame and the rain gutter portion is formed in the outdoor half of the unit frame, so that drainage of rainwater is excellent. In addition to this, rainwater can be effectively prevented from invading, and the rain can be improved.

According to the second aspect of the present invention, since the above-described curtain wall unit is incorporated on the indoor side of the structural material fixed to the building frame, the inner wall surface can have a neat design. In addition, it is possible to positively take in the irregularities of the outer wall surface together with the structural material into the design in consideration of the performance of rain.
