<p><P>PROBLEM TO BE SOLVED: To provide an outside heat insulation fire resistant structure of an exterior wall, capable of effectively imparting excellent heat insulation property and superior fire resistant structure against fire from an outdoor side to the exterior wall constructed by a framework wall construction method. <P>SOLUTION: An outside heat insulation fire resistant structure 10 used for a wooden house building constructed by a framework wall construction method comprises: a structural face material 13 mounted on the outdoor side of jambs 12; a first outer covering substrate material 14; a heat insulation material 15; a first waterproof paper sheet 16; a plurality of vertical furring strips 17; a first aluminum foil layer 18; a second outer covering substrate material 19; a second aluminum foil layer 20; a third outer covering substrate material 21; a second waterproof paper sheet 22; and a lath mortar layer 23. Swell suppression members 25 are arranged so that each swell suppression member 25 is disposed in a space between two adjacent vertical furring strips 17 to suppress the heat insulation material 15 from swelling by heat in a fire disaster. Thus, vertical vent layers 24 formed between the first waterproof paper sheet 16 and the first aluminum foil layer 18 can be held when a fire occurs by interposing the vertical furring strips 17 therebetween. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
