AI Technical Summary

Technical Problem

Existing buildings have numerous ventilation and drainage systems, which are difficult to arrange, control, and maintain, and are also difficult to meet fire-fighting partition requirements.

Method used

The system employs a combination design of fire doors, ventilation baffles, and drainage baffles. When the fire doors are closed, the ventilation baffles cover the ventilation openings, and the drainage baffles block the drainage ditch when the fire doors are closed, thus achieving fire isolation. When the fire doors are open, the ventilation baffles do not affect ventilation, and the drainage baffles do not block drainage, ensuring the normal operation of the system.

Benefits of technology

By sharing ventilation and drainage systems, the number of systems is reduced, layout and control are simplified, and the reliability and efficiency of fire-resistant partitions are improved.

Abstract

The present application relates to the field of fire fighting, and discloses a fire partition system and a comprehensive pipe gallery comprising the same, wherein the comprehensive pipe gallery comprises the fire partition system. The fire partition system comprises a fire door, a ventilation baffle, a ventilation system, a drainage baffle and a drainage system. The ventilation system comprises a ventilation hole, and the ventilation baffle and the ventilation hole are arranged correspondingly to the fire door. The ventilation baffle is matched with the ventilation hole, and the ventilation baffle does not cover the ventilation hole when the fire door is opened and can cover the ventilation hole after the fire door is closed. The drainage system comprises a drainage ditch, and the drainage baffle is matched with the drainage ditch. The drainage baffle is arranged correspondingly to the fire door, and the drainage baffle does not cut off the drainage ditch when the fire door is opened and can cut off the drainage ditch after the fire door is closed. The ventilation baffle is matched with the ventilation hole and can cover the ventilation hole. The ventilation baffle and the drainage baffle are arranged at the fire door to realize the fire partition and the connection.
