Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of civil engineering construction, in particular to a connection structure of a flexible ventilation duct which vertically passes through a seismic isolation layer of a seismic isolation building. Background Art
[0002] In seismically isolated building structures, the isolation layer will undergo significant deformation under the action of an earthquake. When the isolation layer itself has a functional function or is located between the basement and the superstructure, ventilation ducts often exist vertically through the isolation layer. While ensuring the safety of the isolation structure itself, the equipment piping must have sufficient deformation capacity to adapt to the deformation requirements of the isolation structure to ensure its normal operation under the action of an earthquake. This is especially true in lifeline projects with emergency rescue missions after an earthquake, such as hospitals and emergency rescue command centers. If the equipment piping is damaged, the normal use of the building will be affected to a certain extent. Utility Model Content
