Technical Field

[0001] The utility model relates to a curtain wall structure for a building project, in particular to a hidden smoke exhaust window and HVAC air intake structure in a curtain wall system. Background Art

[0002] Most construction projects require the use of smoke exhaust windows. In the event of a fire or emergency firefighting situation, the smoke exhaust windows are opened to allow the indoor smoke and heat to quickly dissipate to the outside, thereby ensuring the safety of indoor personnel and emergency evacuation; and most projects also require HVAC air intakes to be reserved on the building facade to facilitate the HVAC equipment to obtain fresh air from the external environment to supply the indoor environment.

[0003] In existing building construction structures, most smoke exhaust windows and HVAC air intakes are located above the natural layer of the building or above the building facade, directly in contact with the outdoor environment. This practice usually has a certain impact on the beauty and integrity of the building facade, and conflicts with the shop sign system of the commercial building on the ground floor, affecting normal use and posing certain safety hazards.

[0004] Moreover, the smoke exhaust windows and HVAC air intakes are exposed to the external environment. Long-term pollution from external pollutants and wind, sun, rain and snow can easily damage the smoke exhaust windows and HVAC air intakes, causing them to be unable to be used normally and reducing their durability.
