DOUBLE SKIN CURTAIN WALL HAVING EXHAUST HOLE IN VERTICLE FRAME

摘要

PURPOSE: A double outer cover curtain wall including an exhaust hole in a vertical bar is provided to circulate air in a hollow layer by exhausting outer air flowing in the hollow layer by an intake system to the outside through the exhaust hole. CONSTITUTION: A double outer cover curtain wall including an exhaust hole in a vertical bar comprises a horizontal bar, a vertical bar(120), an inner curtain wall(130), an outer curtain wall(140), and an exhaust hole(H). The inner curtain wall and an outer curtain wall are individually arranged on an indoor side and an outdoor side across a hollow layer. The exhaust hole is formed at the vertical bar on an upper side surface and exhausts air of the hollow layer to the outside. A filter net is formed in the exhaust hole and blocks the inflow of outside foreign substances. An intake system is comprised in the lower horizontal bar and intakes the outside air to the hollow layer.
