If it does so, it will be prevented that the cold heat from the stand cooled outdoor is transmitted to the indoor side part of a pushing edge, and it can prevent more reliably the occurrence of dew condensation on the indoor side of a curtain wall.

  In the curtain wall according to the present invention, a vertical water stop material extending in the longitudinal direction of the vertical wall is provided between the vertical and the face material, The structure which contacts the horizontal water stop material provided between the horizontal member and the said face material may be sufficient. If it does so, even if it is the structure which has arrange | positioned the stand on the outdoor side, the water stop around a stand can be ensured reliably.

  In the curtain wall according to the present invention, the connecting members protrude in opposite directions to each other, and fixed to the outdoor side surfaces of the adjacent left and right side members, thereby connecting the adjacent side members to each other, and A structure may be provided that protrudes from the space between the pair of fixed plates to the outdoor side and is fixed to the vertical indoor end surface. If it does so, a stand can be arrange | positioned on the outdoor side using the connection member which connects cross members, and a number of parts can be reduced.

  The curtain wall which concerns on this invention WHEREIN: It is good also as a structure which attached the cover member which covers the fixing plate of the said connection member to the outdoor side surface of the said cross member. If it does so, while being able to prevent that a connection member is exposed on an external appearance, it can be set as a continuous external appearance design, without the connection part of a vertical and a face material interrupting.

  The building according to the present invention is characterized in that the curtain wall having the above-described configuration is used as an outer wall.

  According to the present invention, by placing the stanchion on the outdoor side through a connecting member that is coupled to a cross member, the stanchion that is a strength member is for environmental considerations such as accents on the exterior design of buildings and solar shading. It can also function as a vertical fin. For this reason, while being able to reduce component cost and construction cost, environmental performance can be improved.
