Description

Technical Field

[0001] This utility model belongs to the field of ventilation shaft construction technology, and in particular relates to a sealing structure for ventilation shaft vertical duct. Background Technology

[0002] A ventilation shaft duct is a vertically installed ventilation pipe in a building ventilation system. It is used to connect ventilation equipment on different floors to achieve vertical air transport. It is commonly found in ventilation and smoke exhaust systems in commercial buildings, residences, and other places.

[0003] When constructing vertical ducts in ventilation shafts, gaps may exist at the connection points between the two ends of the duct, potentially leading to air leakage. This not only increases the energy consumption of the ventilation system and wastes energy, but may also introduce outdoor noise and dust, and affect smoke extraction efficiency. Therefore, it is necessary to design a sealing structure for the vertical ducts in ventilation shafts, using a sealing gasket reinforcement structure to seal the gaps at the connection points of the vertical ducts, preventing energy waste caused by air leakage, while also isolating outdoor noise and dust, ensuring a clean and comfortable indoor environment, and reducing safety hazards. Utility Model Content

An edge sealing gasket is installed on the opposite side of multiple corner plates. Four U-shaped frames are engaged on the surface of multiple upper and lower corner plates. Two symmetrical clamping buckles are engaged on the surface of each of the four U-shaped frames. The two clamping buckles are fixedly connected to the corner plates, edge sealing gaskets and U-shaped frames by bolts.

[0006] Preferably, triangular plates are fixedly connected to the left and right sides of the top of the inner cavity of the two supporting steel frames.

[0007] Preferably, a support plate is fixedly connected to the bottom of the fixing plate by bolts, and the support plate is fixedly connected to the vertical air duct of the lower air shaft by bolts.

[0008] Preferably, the bottom of the four U-shaped frames is provided with a vertical plate, which is fixedly connected to the clamping buckle by bolts.
