In FIG. 13, on the 1st board 1a used as the outer board, the 1st plate-shaped heat insulating material 2a consisting of the heat insulating material arrange | positioned on the 1st board 1a, and the 1st plate-shaped heat insulating material 2a A second plate-like heat insulating material 2b made of a heat insulating material disposed on a plurality of vacuum heat insulating members 3b arranged in parallel with the seal portion 3a facing each other; A second plate 1b serving as an inner plate disposed on the plate-shaped heat insulating material 2b, a first plate-shaped heat insulating material 2a between the first plate 1a and the second plate 1b, and a vacuum heat insulating member 3b, and filled heat insulating materials 4a and 4b disposed in a portion surrounded by the second plate-shaped heat insulating material 2b. The filled heat insulating materials 4a and 4b are adjacent to the vacuum heat insulating member 3b and the first filled heat insulating material 4a. And the second filling heat insulating material 4b that is superposed on the sealing portion 3a of the adjacent vacuum heat insulating member 3b, the first filling heat insulating material 4a and the second filling breaker It is sandwiched between the wood 4b.

Thus, by fixing the vacuum heat insulating material through the seal portion of the vacuum heat insulating material, it becomes possible to fix without using a nail or a screw. It is considered that a heat insulating structure having a high heat insulating effect can be provided without being damaged.

  As described above, the house according to the present embodiment is formed on at least a part of the existing floor of the house formed of the outer wall member 302, the pillar 303, and the inner wall member 304 to form an indoor space, and the indoor side surface of the inner wall member 304. A plurality of vacuum heat insulating materials 305 disposed, a trunk rim 306 disposed on the surface of the vacuum heat insulating material 305 on the inner side of the chamber, and a vacuum heat insulating material 305 and a trunk rim 306 fixed to the interior side of the trunk 306 It is a house having a stab prevention plate 307 that covers from the inside, and the vacuum heat insulating material 305 has a plurality of core materials arranged at predetermined intervals in a direction substantially perpendicular to the thickness direction, and the heat welding layers Adhering parts of the outer jacket material that do not have a core material between the outer jacket materials so that the core materials are positioned in a space independent of each other between the gas barrier coating materials facing each other. Multiple core materials by heat-welding the jacket materials Sealed under reduced pressure in the jacket material, all the jacket materials where the jacket materials are in close contact with each other are thermally welded, and the core between the jacket materials when viewed in the thickness direction of the core material A core material part 310 with a material, and a core materialless part 311 without a core material between the jacket materials when viewed in the thickness direction of the core material, and a core material part 310 of the vacuum heat insulating material 305, It is attached to the inner wall material 304 so that the coreless part 311 of the adjacent vacuum heat insulating material 305 overlaps, and the coreless part 311 located near the corner of the vacuum heat insulating material 305 follows the shape of the trunk edge 306. The interior side surface of the trunk 306 is not in contact with the core part 310 of the vacuum heat insulating material 305 and is in contact with at least a part of the coreless part 311.

  In the above-described configuration, the inner surface of the trunk 306 has the inner surface of the vacuum heat insulating material 305 so that the coreless portion 311 of the vacuum heat insulating material 305 located near the corner of the vacuum heat insulating material 305 follows the shape of the trunk heat 306. In addition to being in contact with at least a part of the coreless portion 311 without being in contact with the core material portion 310, the vacuum heat insulating material 305 is a plurality of vacuum insulators 305 that are arranged at predetermined intervals in a direction substantially perpendicular to the thickness direction. Between the jacket materials so that each of the core materials is located in a space independent of each other between the gas barrier jacket materials facing each other with the heat-welding layers. The outer cover materials are closely adhered to each other, and the adhered outer cover materials are thermally welded to each other so that a plurality of core materials are sealed under reduced pressure in the outer cover material. Since the jacket materials are heat-sealed, multiple core materials are sealed under reduced pressure. In addition, since the jacket material conforms to the shape of a plurality of core materials at the same time, the core material-less portion 311 located between the core material and the other core materials located around the core material has one core material. It becomes smoother than the coreless portion obtained when sealed under reduced pressure. In addition, the fixing tool 308 is provided so that the undulation of the coreless portion 311 is eliminated even in a portion where the coreless portion 311 of the vacuum heat insulating material 305 and the surrounding coreless portion 311 of the vacuum heat insulating material 305 overlap. Since it is used and fixed to the interior material 304, the overlap between the coreless portions 311 does not affect the installation state of the trunk edge 306. Thereby, it is possible to prevent the trunk edge 306 from being deformed along with the deformation of the coreless part 311 located around the core part 310, and the trunk edge 306 is placed on the indoor side of either the wall, ceiling, or floor. It can be installed parallel to the surface of the. Thereby, the stab preventing plate 307 can be installed in parallel with the inner wall such as a wall, a ceiling, or a floor, and a step generated at the joint between the stab preventing plates 307 can be suppressed.

  Since the housing of the present invention can suppress the level difference occurring at the seam between the walls such as the stab prevention plate due to the vacuum heat insulating material, the building such as a new house, an existing house, a commercial facility, a factory, an office, etc. It is also applicable to.
