AI Technical Summary
Technical Problem
Existing smoke shaft arrangements face challenges in achieving efficient installation, tightness against air and gas passage, and effective heat insulation, particularly in preventing heat transmission during fires.
Method used
A new smoke shaft arrangement featuring a seal structure with a sealing layer made of intumescent material and a heat insulation material layer comprising mineral fibers, which provides enhanced heat insulation and sealing capabilities.
Benefits of technology
The solution effectively prevents heat transmission from the smoke shaft during fires by using intumescent material that expands to fill gaps, and provides efficient heat insulation using mineral fibers, thereby ensuring the integrity of the smoke shaft arrangement.
