Abstract
This application relates to the field of architecture and provides a duct-to-curtain wall connection structure, including a duct assembly and a curtain wall structure, both installed on the exterior wall. The duct assembly further includes an extension connector, which connects to the curtain wall. The duct assembly has openings at both ends, one for an indoor area and the other for an outdoor area. A rainproof louver is also provided at the outdoor area opening. The extension connector is further provided with a filling and sealing structure, which fills the gaps or holes between the duct assembly and the curtain wall structure, and between the duct assembly and the rainproof louver. This application effectively seals the gaps or holes between the duct and the curtain wall in a building structure.
