A fixing portion 39a of the indoor side glass 20 is provided on the outdoor side of the intermediate frame 39 and between the ceiling frame 8 and a fixing portion 39b of the fireproof board 28 is provided on the upper side. The intermediate frame 39 has a flat plate portion 39c that is in contact with the blindfold plate 29 in the vicinity of the center in the prospective direction of the space 21, and is provided with the flat plate portion 39c, the blindfold plate 29, the fixed portion 39a, and the fixed portion 39b. The space | gap 40 is provided between the site | parts.

  The gap 40 is provided with a hollow corner member 41 spanned between the two vertical frames 24, and the blind 14 is suspended from the hollow corner member 41. The blind 14 is disposed so as not to be exposed to the outside by being accommodated in the gap 40 between the intermediate frame 39 and the blindfold plate 29 in a state where it is pulled upward. Further, the surface on the outdoor side of the flat plate portion 39 c forming the gap 40 is formed so that the contour is substantially connected to the inner surface of the upper guide wall 36 b forming the outflow path 36 a of the upper frame 36. For this reason, there is no member protruding in the region directly below the opening 36e on the space 21 side of the outflow path 36a, and the space 21 continues to the opening of the inflow path 30a of the lower frame 30.

  According to the curtain wall 10 of the present embodiment, the blind 14 is provided in the space 21 with a position in the prospective direction different from the opening 36e on the space 21 side of the outflow path 36a. Does not block the outflow of air. For this reason, it is possible to efficiently suppress an increase in the temperature of the space 21 between the indoor side glass 20 and the outdoor side glass 22. In particular, when the air in the space 21 heated by sunlight irradiated to the blind 14 rises and flows out from the outflow path 36 a above the outdoor side glass 22, the inflow path below the outdoor side glass 22. Since the outside air flows in from 30a, it is possible to circulate the air smoothly and efficiently suppress the temperature rise.

  Further, since the lower guide wall 30b is provided in the inflow path 30a to guide the outside air that has entered into the space 21 inward and upward, the outside air that has entered the inflow path 30a is separated into the space 21 by the lower guide wall 30b. It is possible to efficiently flow out air from the outflow path 36a that is guided inwardly and upwardly and flows smoothly toward the upper outflow path 36a and rises in temperature.

  Furthermore, since the upper guide wall 36b for guiding the air in the space 21 upward and outdoors is provided in the outflow path 36a, the air warmed in the space 21 rises and the upper guide wall It is guided upwards and outdoors by 36b and smoothly flows out outdoors. For this reason, it is possible to more efficiently flow the air whose temperature has risen from the outflow path 36a.

  That is, since both the lower guide wall 30b of the inflow passage 30a and the upper guide wall 36b of the outflow passage 36a act to circulate air smoothly, the temperature rise of the air in the space 21 can be efficiently suppressed.

  In the curtain wall 10 of the present embodiment, the lower frame 30 that forms the inflow passage 30a and the upper frame 36 that forms the outflow passage 36a are made of the same extruded aluminum member. Costs can be reduced and management is easy because the types of members used are reduced.

  Further, since the louver 25 is provided on the outdoor side of the inflow path 30a and the outflow path 36a, the louver 25 is inclined downward toward the outside. It is possible to flow downward toward the outside. For this reason, even if the inflow path 30a is provided adjacent to the upper part of the outflow path 36a as in the present embodiment, the air that has been warmed and has flowed out of the outflow path 36a is prevented from flowing into the inflow path 30a immediately thereafter. Is possible. Further, since the louver 25 is inclined downward toward the outdoor side, it is possible to prevent rainwater or the like from directly entering the space 21 from the inflow path 30a and the outflow path 36a.

  In the said embodiment, although the indoor side glass 20 was used as the multilayer glass, it is not restricted to this.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
