PURPOSE: An exhaust air duct installation structure of a ventilator for a building is provided to cut down the construction expenses by reducing the time and manpower required for construction, and to prevent a water leakage in a gap by heightening the binding strength between a sleeve body and a floor concrete layer. CONSTITUTION: As for installing a lower body(130a) of an exhaust air duct(130) assembled with a ventilator(150) around a hole(143) for an air pipe(160) of a building slab(140) where an adiabatic layer(141) and a concrete layer(142) are piled up upward, the exhaust air duct installation structure of a ventilator for a building comprises the steps of installing a sleeve body(120) having the function as a form around a hole(143) of a building slab(140) and forming an end sill part(110) by placing plain concrete inward, and fixing a lower body(130a) of an exhaust air duct(130). |
