EAVES SOFFIT VENTILATOR AND EAVES SOFFIT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an eaves soffit ventilator and an eaves soffit structure capable of usually ensuring a fine ventilating passage while preventing the air from directly blowing into an eaves soffit plenum from an eaves and effectively making heat insulation therebetween by quickly reacting with a temperature rising resulting from a fire.;SOLUTION: The eaves soffit ventilator is equipped with passage formation members 26 and 28 for forming a ventilating passage connecting a roof space entrance 33 to an eaves soffit opening 32. A passage control section 28b hanging down from the ceiling 28a is located in a position cutting off the passage connecting the eaves soffit opening 32 to the roof space entrance 33 to control the air directly blowing into the roof space entrance 33 from the eaves soffit opening 32. A heat expansion material 36 fixed to the side of the passage control section 28b is expanded sideways in the case of temperature rising to make press-contact to an opposite side wall 26b to cut off the ventilating passage in the right below the roof space entrance 33.;COPYRIGHT: (C)2004,JPO&NCIPI
