And the water that permeates through a slight gap on the outdoor side of the contact surfaces 12aa, 13aa flows between the contact surfaces 12aa, 13aa and soaks into the indoor side, but the first projecting portion 12b of the first end seal material 12 and It guides by the hanging part 13e provided in the 2nd edge part sealing material 13 between the 2nd protrusion parts 12c, and falls below.
As a result, the soaking water is prevented from flowing into the indoor side and dropped downward, and returned to the outside through the gap.

  In the curtain wall according to the prior art, water such as rainwater that permeates into the contact surfaces 12aa and 13aa of the first end seal material 12 and the second end seal material 13 is the first end seal material 12 and the second end portion. It was guided by a slit-like cavity formed in the sealing material 13 and dropped downward. However, in this case, the first end seal material 12 and the second end seal material 13 require a thickness of, for example, about 20 millimeters in order to ensure strength while forming a slit. Then, in order not to form the slit which guides the fall of the water which permeates, the 1st end part sealing material 12 and the 2nd end sealing material 13 can be reduced to the thickness of about 1/2 of that, for example, and can be reduced in size.

  Further, when the left and right units 2 are coupled, the first end seal member 12 of the unit 2A and the second end seal member 13 of the unit 2B are brought into close contact with each other so that the first protrusion 12b and the second protrusion 12c are connected to the second end. It was made to fit in the lower part of the part sealing material 13. And the 1st projection part 12b and the 2nd projection part 12c were supported by the 1st convex side vertical wall 15 and the 2nd convex side vertical wall 16. As shown in FIG.

  Therefore, when four curtain wall units 2 adjacent in the vertical and horizontal directions are locked to each other at the intersection P during an earthquake or the like, the first end seal member 12 and the second end seal member 13 are locked to each other. And the 1st end part sealing material 12 locks in the state in which the 1st projection part 12b and the 2nd projection part 12c are located in the clearance gap between the 1st concave side vertical wall 18 and the 2nd concave side vertical wall 19. FIG.

And the 1st convex side vertical wall 15 and the 2nd convex side vertical wall 16 are the 1st concave side vertical wall 18 and the 2nd concave side of the vertical frame 7 via the 1st elastic sealing material 15a and the 2nd elastic sealing material 16a. The first convex-side vertical wall 15 and the second convex-side vertical wall 16 and the first concave-side vertical wall 18 and the second concave-side vertical wall 19 are in contact with each other and scratched during locking. There is no damage or damage. Moreover, since the first protrusion 12b and the second protrusion 12c are interposed between the upper ends of the first convex side vertical wall 15 and the second convex side vertical wall 16 and the lower surface of the upper frame 4, they do not interfere with each other. , The movement is not restricted and the left / right swinging is not irregular.
In addition, the first convex side vertical wall 15 and the second convex side vertical wall 16 and the vertical frame 6 and the first concave side vertical wall 18 and the second concave side vertical wall 19 and the vertical frame 7 are locked by the same amount, They can prevent each other's rubbing and deformation, and return to the original position at the end of the earthquake.

As described above, according to the curtain wall 1 according to the present embodiment, the first protrusion 12b and the second protrusion 12c provided on the first end seal material 12 of the unit 2A are connected to the first convex vertical wall 15 and the second protrusion 12c. Supported by the convex vertical wall 16 and disposed below the upper frame 4 of the unit 2B and held between the first concave vertical wall 18 and the second concave vertical wall 19 of the second end seal member 13. Therefore, the first convex side vertical wall 15 and the second convex side vertical wall 16 can be held in contact with the first concave side vertical wall 18 and the second concave side vertical wall 19.
Moreover, since the first and second protrusions 12b and 12c are provided on the first end seal material 12 of the vertical frame 6, the heights of the first convex side vertical wall 15 and the second convex side vertical wall 16 that support the first and second protrusions Is low and does not interfere with the upper frame 4.
Therefore, even when the curtain wall units 2 adjacent to each other in the curtain wall 1 are locked due to an earthquake or the like, the first protruding portion 12b and the second protruding portion 12c of the first end seal material 12 are connected to the first concave side vertical wall 18 and the second The two concave side vertical walls 19 can be regularly locked to the same amount, and can be prevented from following each other without interfering with each other, preventing mutual damage.

In addition, even if water such as rainwater penetrates from the gap between the contact surfaces 12aa, 13aa of the first end seal material 12 and the second end seal material 13, the first and second protrusions 12b, Since it is guided by the hanging portion 13e of the second end seal member 13 provided between 12c and falls as water droplets downward, it can be prevented from oozing out indoors. In addition, it is not necessary to provide a slit or the like for guiding water in the first and second end seal materials 12 and 13, and the thickness can be reduced to, for example, about 1/2.
Further, the first projecting portion 12b and the second projecting portion 12c of the first end portion sealing material 12 are inclined and opened outward at the part stage, and these are opened to the first convex side vertical wall 15, the second convex side vertical portion. When being mounted on the upper portion of the wall 16, the first protrusion 12 b and the second protrusion 12 c are fitted to the lower side of the second end seal member 13 so that the water-tightness of this portion is corrected.
