AI Technical Summary
Existing basement ventilation shafts in seismically isolated buildings have cracked due to displacement of the seismic isolation layer, and the ventilation path is singular, making it difficult to meet the needs of mechanical air supply and rain and dust protection.
Design a basement air supply shaft structure for a seismic isolation building, including a seismic isolation layer, an air supply shaft, an S-shaped air duct, flexible caulking, and a horizontal displacement gap. Combined with a waterproof coating and roll material, it ensures that the structure can deform freely during an earthquake and is ventilated to the outside through the S-shaped air duct. Louvers are installed for rain protection.
It effectively avoids shaft cracking, improves ventilation efficiency and rain protection, utilizes the space of the seismic isolation trench, adapts to seismic isolation displacement, and enhances ventilation performance and rainwater drainage efficiency.
