<p><P>PROBLEM TO BE SOLVED: To provide an airtight structure capable of reducing the number of working man-hours during manufacturing. <P>SOLUTION: On a rear face side of an inner wall material 21 installed on a sub-floor material 32, an in-wall heat insulation material 23 which is configured by covering a fiber-based heat insulation material 27 formed into a plate-like form with a bag body 26 is provided along the rear face side of the inner wall material 21. A lug part 28 extending out of the peripheral edge of the fiber-based heat insulation material 27 is provided on a part of the bag body 26. In the lug part 28, a lower lug part 28a extending from the lower side of the fiber-based heat insulation material 27 extends to the surface side of the inner wall material 21 through between the lower end part of the inner wall material 21 and the sub-floor material 32, and a part of the lower lug part 28a is sandwiched between the sub-floor material 32 and a floor finishing material 33 laid thereon. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
