Description

  The present invention relates to a building wall using a vacuum heat insulating material.

  In recent years, as a countermeasure for global warming, which is an environmental problem, not only consumer equipment and industrial equipment but also a movement to promote energy saving of buildings has become active.

  A common way to save energy in a building is to reduce the amount of heat entering from the outside by increasing the thickness of a conventionally used heat insulating material. However, when the thickness of the heat insulating material is increased, the thickness of the pillars and frames that are the skeleton of the building is also increased, so that there is a problem that the amount of material used increases.

  In order to solve this problem, a heat insulating panel has been reported in which a part of the heat insulating material fitted between the shafts composed of a base, a pillar, a beam, a girder and the like is replaced with a vacuum heat insulating material (for example, Patent Documents). 1).

  FIG. 9 is a cross-sectional view of a conventional heat insulation panel described in Patent Document 1.

  The conventional heat insulation panel 1 is integrally provided by attaching a flexible and elastic band-shaped airtight material 17 to the flange portion on the outer periphery of one side of the load bearing wall surface material 2, and inside the shaft assembly. A flexible and elastic band-like shape is formed around the side surface of the frame body 3 made of wood or resin, which is formed to be slightly smaller to match the shape, and is integrated on the same side of the face material 2 with a fixing tool 12 such as a wood screw. The airtight material 17 is provided integrally. On the opposite side of the face material 2 of the frame 3, a moisture-proof paper 15 having a moisture-proof performance as a receiver for the injection foaming of hard polyurethane is stuck on the entire surface. On the face material 2 surrounded by the frame 3, a vacuum heat insulating material 5 formed by covering the core material with a jacket material having gas barrier properties and sealing the inside of the jacket material under reduced pressure is fixed by an adhesive.

  The vacuum heat insulating material 5 is arranged in a state in which a fin portion made of only a jacket material located on the outer periphery of the core material is folded on a heat transfer surface on the side opposite to the face material 2. Between the vacuum heat insulating material 5 and the moisture-proof paper 15, hard foamed polyurethane is foam filled as the heat insulating material 4.

  The heat insulating panel 1 is configured by fitting a panel body constituted by the frame 3, the vacuum heat insulating material 5, the heat insulating material 4, the moisture-proof paper 5 and the airtight material 17 into the shaft assembly and fixing the bearing wall face material 2 with nails. It is used to construct a physical strength wall. At that time, the airtight member 17 provided on the bearing wall surface material 2 is sandwiched between the outer peripheral surface of the pillar, the intermediate column, the base, the girder and the like constituting the shaft assembly and the bearing wall surface material 2 so as to fill the gap. However, since it has sufficient flexibility and elasticity, it deforms and adheres to form an airtight layer. On the other hand, the airtight member 17 provided on the frame body 3 is sandwiched between the frame body 3 and the inner peripheral surface of the shaft assembly so as to fill the gap. However, as described above, the airtight material 17 is deformed because it has sufficient flexibility and elasticity. Adheres closely to form a heat insulating and airtight layer.

  Further, another frame body 3 is connected to the frame body 3 via the moisture-proof paper 15 by a fixing tool 12 such as a nail, thereby adjusting the thickness of the panel and fixing the moisture-proof paper 15.

The conventional heat insulation panel 1 having the above-described structure replaces a part of the heat insulating material 4 filled between the bearing wall face material 2 and the frame 3 with the vacuum heat insulating material 5, so that the heat insulating performance is increased without increasing the amount of materials. It is said that can be increased.
