Abstract

Abstract: Ventilation duct is an important building component in the building, which can reduce fire loss and ensure the safety of people's life and property. The fire resistance limit of ventilation duct was tested by standard experimental method, and the fire integrity and fire insulation of ventilation ducts with different pipe thicknesses and different cement mortar thicknesses were studied. The experimental results have important reference value for the implementation of JG/T 194-2018 Ventilating duct for residential kitchen and bathroom. The corresponding improvement measures and suggestions are put forward to optimice the test procedure for ventilation ducts.

Key words: ventilating duct, fire test, insulation
