Fixing to the wiring fixing member is performed. As described above, by interrupting the communication between the room and the space between the heat insulating material and the case, the warmed air in the room is prevented from entering the space, and the condensation on the wall of the case is generated. It is done to suppress.

Patent No. 6047139

  However, when the airtight member is disposed on the inner side of the wire fixing member, the airtight member may contact other members in the wire fixing member, or the airtight member may be perforated by the mounting screw of the cover. There was a risk of loss. As a result, there is a possibility that the communication between the room and the space between the heat insulating material and the housing can not be shut off.

  The present invention has been made in view of the above-described circumstances, and it is an object of the present invention to provide a heat insulating structure capable of reliably blocking communication between a room and a space between a heat insulating material and a housing. Do.

In order to solve the above-mentioned subject, the present invention proposes the following means.
The heat insulating structure according to the present invention is a heat insulating structure including a casing of a building, a heat insulating material, and a base material, and an interior material in which the heat insulating material is disposed facing the wall surface of the housing. An opening is formed in the interior material in which a wiring fixing member is accommodated, and the interior material is provided with an airtight material which covers the opening from the heat insulating material side.

  Further, in the method of installing an interior material according to the present invention, an opening portion, in which the wire fixing member is accommodated, of the interior material in which the heat insulation material and the base material are integrally formed is covered with the airtight material from the heat insulation material side. At the same time, the interior material is disposed such that the heat insulating material faces the wall surface of the frame of the building.

  According to these inventions, the opening formed in the interior material and in which the wiring fixing member is accommodated is covered with the airtight material from the heat insulating material side. For this reason, the airtight member is not located inside the wiring fixing member, and it is possible to avoid the mounting screw and other members in the wiring fixing member from coming into contact with the airtight member. Therefore, it is possible to prevent the loss of the airtight material, and it is possible to reliably shut off the communication between the room and the space between the heat insulating material and the casing.

Further, the heat insulating material and the base material in the interior material are integrally formed in advance prior to the application to the wall surface. For this reason, when the airtight member is temporarily disposed inside the wiring fixing member, the end portion of the airtight member can not be sandwiched by the heat insulating material and the base material, and is sandwiched and fixed by the wiring fixing member and the cover. It will be. As a result, the end portion of the airtight material may protrude to the inner surface of the interior material on the outer side of the wiring fixing member and the appearance may be deteriorated.
On the other hand, in the present invention, since the airtight material covers the opening from the heat insulating material side, the end of the airtight material does not protrude to the inner surface of the interior material, and the deterioration of the appearance can be prevented.

  Further, the airtight material may be formed of a thin film material.

  In this case, since the airtight material is formed of a thin film material, it is possible to prevent the airtight material from being bulky and to ensure the handleability and the workability of the airtight material.

  Further, the wiring fixing member is further provided with a fixing member for fixing the wiring fixing member to the interior material, and the airtight material is provided to the opening in the front view than the fixing member on the outer surface of the interior material on the heat insulating material side. It may be fixed to the outside.

  In this case, since the airtight material is fixed to the opening with respect to the outer side than the fixing member, it is possible to reliably prevent the airtight material from coming into contact with the fixing member and losing it.

  According to the present invention, the communication between the room and the space between the heat insulating material and the housing can be reliably shut off.

The heat insulating material 21 is preferably glass fiber mixed paper, a glass fiber non-woven fabric, or a polyester non-woven fabric, from the viewpoint of adhesiveness with the airtight material 30 described later.
Further, among the interior materials 20, at least the heat insulating material 21 is airtight, and the moisture permeability coefficient at a thickness of 25 mm is 200 ng / (m ² · s · Pa) or less, and 100 ng / (m ² · s · Pa) or less is preferable, 60 ng / (m ² · s · Pa) or less is more preferable, and 50 ng / (m ² · s · Pa) or less is most preferable.
The thickness of the heat insulating material 21 is 15 mm or more in order to obtain sufficient heat insulation, 40 mm or less in order to widen the indoor space, and preferably 20 mm or more and 30 mm or less.

  Examples of the base material 22 include gypsum board, water resistant gypsum board, plywood, galvanized steel plate, calcium silicate board, wood cement board and structural panel, particle board, sheathing board, MDF, hard board, laminated fiber board, structure For example, wood-based boards such as plywood and rock wool sound absorbing boards are used. It is preferable that the interior material 20 be easily processed by a cutter, a circular saw or the like on site.

In the interior material 20, an opening 20A in which the wiring fixing member 50 is accommodated is formed. The opening 20A has a rectangular shape in which two sides extend in the vertical direction Z and the other two sides extend in the orthogonal direction Y. In the opening 20A, the size in the vertical direction Z is larger than the size in the orthogonal direction Y.
The wiring fixing member 50 has a box shape. The wiring fixing member 50 has a rectangular shape formed smaller than the opening 20A in a front view as viewed from the opposing direction X. The wiring fixing member 50 is opened toward the indoor side in the opposing direction X. The opening of the wiring fixing member 50 is covered by a cover 60.

  An insertion port (not shown) is formed on the housing 10 side in the corresponding direction of the wiring fixing member 50. A wire 70 passing between the housing 10 and the interior material 20 is inserted through the insertion port. In the wiring fixing member 50, for example, a wiring device (not shown) such as a power supply device or a communication device is accommodated.

The heat insulating structure 1 further includes a fixing member 80 that fixes the wiring fixing member 50 to the interior material 20. The fixing members 80 are paired at positions sandwiching the wiring fixing member 50 in the orthogonal direction Y, and a plurality of the fixing members 80 are arranged at intervals in the vertical direction. In the illustrated example, a long screw is used as the fixing member 80.
The fixing member 80 fixes the wiring fixing member 50 to the interior material 20 together with the cover 60. The fixing member 80 integrally penetrates the heat insulating material 21 and the base material 22 in the interior material 20.

And the heat insulation structure 1 which concerns on this embodiment is provided with the airtight material 30 which covers 20 A of opening parts from the heat insulation material 21 side. The airtight material 30 is formed of a thin film material.
The airtight member 30 adheres to the outer side in the orthogonal direction Y and the vertical direction Z with respect to the opening 20A on the outer surface of the interior material 20 on the heat insulating material 21 side in a front view as viewed from the opposite direction X It is done. The airtight material 30 is fixed to the outer surface on the side of the heat insulating material 21 by, for example, an adhesive. The airtight member 30 is formed with an insertion portion (not shown) for inserting the wiring 70.

Next, the construction method of the interior material 20 which concerns on this embodiment is demonstrated.
In the construction method of the interior material 20 according to the present embodiment, first, the opening 20A of the interior material 20 is covered with the airtight material 30 from the heat insulating material 21 side in the opposing direction X. Then, the airtight material 30 is fixed to the outer surface of the interior material 20 on the heat insulating material 21 side. Under the present circumstances, the position where the fixing member 80 is arrange | positioned is confirmed, and the airtight member 30 is the orthogonal direction Y and the up-down direction Z with respect to the opening 20A in front view seen from the opposing direction X rather than the fixing member 80. Stick to the outside.

  Next, the wiring fixing member 50 is accommodated in the opening 20A from the side of the base material 22 in the opposite direction X in a state where the wiring device is disposed inside. After the wiring fixing member 50 is accommodated in the opening 20A of the interior material 20, the opening 20A of the interior material 20 may be covered with the airtight material 30. Also, the wiring fixture may be disposed inside the wiring fixing member 50 after the wiring fixing member 50 is accommodated in the opening 20A.

  Then, the interior material 20 is disposed on the wall surface 10A of the frame 10 of the building. When arranging the interior material 20, the interior material 20 is arranged on the wall surface 10A in a state where the heat insulating material 21 is directed to the wall surface 10A of the housing 10. The interior material 20 is fixed to the wall surface 10A of the housing 10 by an adhesive (not shown). At this time, due to the unevenness of the wall surface 10A of the housing 10, a space is formed between the wall surface 10A of the housing 10 and the heat insulating material 21.

Next, modifications of the wiring fixing member 50 will be described.
As shown in FIG. 2, the wiring fixing member 50B according to the modification is constituted by a plurality of plates. The wiring fixing member 50B includes a first plate 51 disposed on the outer surface of the interior material 20 on the side of the heat insulating material 21 and a second plate 52 disposed on the interior surface of the interior material 20 on the indoor side. The first plate 51 and the second plate 52 are connected to each other by a connecting member 53 inserted into the opening 20A.

The first plate 51 is disposed on the inner side of the opening 20A in the orthogonal direction Y and the vertical direction Z in a front view as viewed from the opposing direction X relative to the fixing member 80. The second plate 52 is sandwiched in the opposing direction X by the base material 22 of the interior material 20 and the cover 60, and is fixed to the interior material 20 by the fixing member 80. The first plate 51 and the second plate 52 sandwich the interior material 20 in the opposing direction X.
As described above, by adopting the wiring fixing member 50B formed of a plurality of plates, the wiring fixing member 50B can be made compact, and the wiring fixing member 50B can be attached to the opening 20A having a small opening area.

As described above, according to the heat insulating structure 1 according to the present embodiment, the opening 20A formed in the interior material 20 and in which the wiring fixing member 50 is accommodated is covered with the airtight material 30 from the heat insulating material 21 side. There is.
For this reason, the airtight member 30 is not located inside the wiring fixing member 50, and it is possible to prevent the mounting screw and other members in the wiring fixing member 50 from coming into contact with the airtight member 30. Become. For this reason, the defect of the airtight material 30 can be prevented, and the communication between the room and the space between the heat insulating material 21 and the housing 10 can be reliably cut off.

Moreover, the heat insulating material 21 and the base material 22 in the interior material 20 are previously integrally formed before the installation to the wall surface 10A. For this reason, when the airtight member 30 is temporarily disposed inside the wiring fixing member 50, the end portion of the airtight member 30 can not be sandwiched and fixed by the heat insulating material 21 and the base member 22. And the cover 60 hold and fix. As a result, the end of the airtight member 30 may protrude to the inner surface of the interior member 20 on the outside of the wiring fixing member 50 and the appearance may be deteriorated.
On the other hand, in the present invention, since the airtight material 30 covers the opening 20A from the heat insulating material 21 side, the end of the airtight material 30 does not protrude to the inner surface of the interior material 20, and the deterioration of the appearance can be prevented.

Moreover, since the airtight material 30 is formed of a thin film material, it is possible to prevent the airtight material 30 from being bulky and to ensure the handleability and the workability of the airtight material 30.
In addition, since the airtight member 30 is fixed to the opening 20A outside the fixing member 80, the airtight member 30 can be reliably prevented from coming into contact with the fixing member 80 and being broken.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.

  For example, in the above-mentioned embodiment, although the composition in which a wiring fixture is arranged inside was shown as wiring fixed member 50, it is not restricted to such a mode. It may replace with the wiring fixing member 50, and may employ | adopt the piping box which accommodates piping apparatus like a gas pipe or a water pipe. This is because the same function and effect can be achieved in the heat insulating structure 1 regardless of the type of the device to be accommodated inside.

  In the above embodiment, the airtight member 30 is fixed to the outside of the opening 20A with respect to the fixing member 80 on the outer surface of the interior material 20 on the heat insulating material 21 side. It is not limited to The airtight member 30 may be fixed to the inside of the opening 20A more than the fixing member 80.

  In addition, it is possible to replace components in the embodiment with known components as appropriate without departing from the spirit of the present invention, and the above-described modifications may be combined as appropriate.
