The invention discloses a method for detecting the fireproof performance of a cavity floor slab with a built-in smoke exhaust and ventilation pipeline. The fireproof performance of the cavity floor slab with the built-in smoke exhaust and ventilation pipeline is detected according to internal fire conditions and external fire conditions. The fireproof performance of the cavity floor slab with the built-in smoke exhaust and ventilation pipeline can be well detected, the fireproof performance of the cavity floor slab with the built-in smoke exhaust and ventilation pipeline is detected according to the internal fire condition and the external fire condition, and the detection result of the fireproof performance can be more comprehensive and more accurate. 本发明公开了一种内置排烟通风管道的空腔楼板防火性能的检测方法，按照内部受火条件和外部受火条件分别对内置排烟通风管道的空腔楼板防火性能进行检测；能够很好的对内置排烟通风管道的空腔楼板防火性能进行检测，按照内部受火条件和外部受火条件分别对内置排烟通风管道的空腔楼板防火性能进行检测，能够使防火性能的检测结果更加全面，更加准确。
