Description

Technical Field

[0001] The utility model relates to the technical field of air duct construction, in particular to an air duct installation device suitable for a vertical shaft. Background Art

[0002] During the construction of building structures, vertical pipes such as ventilation ducts, fire-fighting pressurized air supply ducts and fire-fighting smoke exhaust ducts are usually installed. The above vertical pipes are collectively referred to as shaft air ducts. The main function of shaft air ducts is ventilation. They can also be used for pipeline layout and installation of various mechanical and electrical specialties. According to the Technical Standard for Building Smoke and Exhaust Systems (GB 51251-2017), when the fire elevator vestibule cannot be equipped with a natural ventilation system, a mechanical pressurized air supply system should be used. Therefore, many fire elevator vestibules are equipped with mechanical pressurized air supply systems, which are delivered to the elevator vestibule by a blower through a shaft air duct.

[0003] At present, the design of the shaft air duct in the building structure is usually to form a shear wall at the elevator shaft. Although the lateral stiffness of the building is enhanced, it results in shear wall structures on at least two sides of the shaft. The shear wall structure has been completed before the air duct is installed, and the existing air duct connection and installation method mainly uses bolts to connect the outer flanges of two adjacent sections of the air duct. Since the distance between the outer wall of the shaft air duct and the shaft wall is relatively small, the operating space is narrow, and the short side air duct can barely be operated with one hand, but more than half of the long side air duct cannot be connected. The existing bolt and outer flange air duct connection structure is difficult to achieve the connection between two adjacent air duct sections, it is difficult to ensure that all bolts between two adjacent air duct sections can be fully tightened, and it is difficult to ensure the connection quality of the air duct, which causes great difficulties for the installation of the shaft air duct.
