It is process drawing which shows the process made into a heat insulation wall.

  The house 1 as an example of the building in Embodiment 1 of this invention has the heat insulation reinforcement | strengthening structure 5 with respect to the wall 2, the ceiling 3, and the floor 4 in FIG. The wall 2 having the heat insulation strengthening structure 5 may be the first floor or the second floor, and the number of floors is not limited. The outdoor side may be outdoors or indoors. However, since the temperature difference between the indoor and outdoor is generally large, the effect of the present invention is higher when the outdoor side is outdoor.

  Moreover, the heat insulation reinforcement | strengthening structure 5 is not only constructed | assembled with respect to the whole house, It is also possible to construct only in the space where a resident mainly lives.

  As shown in FIGS. 2, 3, 4, 6, 7, and 8, the house 1 of the present embodiment includes a wall 2, a ceiling 3, a floor 4, and a wall 2 and a ceiling that form an indoor space. In a direction perpendicular to the indoor surface of any one of the wall 2, the ceiling 3, and the floor 4, the vacuum heat insulating material 6 disposed on at least a part of the indoor surface of any one of the floor 3 and the floor 4 The trunk edge 7 disposed so as not to overlap the vacuum heat insulating material 6 and the vacuum heat insulating material 6 and the trunk edge 7 disposed so as to come into contact with the interior side surface of the trunk edge 7 are covered from the indoor side. It is a building having interior materials 8a and 8b made of a plurality of plate-like gypsum boards and a fixing member 26 that penetrates the interior materials 8a and 8b and sticks to the trunk edge 7 to fix the interior materials 8a and 8b.

  There is a trunk edge 7 on the opposite side of the abutting portion 9 where the ends of the adjacent interior materials 8a and 8b are abutted, and the opposite end of the abutting portion 9 where the ends of the adjacent interior materials 8a and 8b are abutted.

Is stuck.

  In addition, the vacuum heat insulating material 6 is obtained by covering a rectangular core material 11 with a covering material 12 having gas barrier properties and sealing under reduced pressure.

  Moreover, the trunk edge 7 has substantially the same thickness as the core material 11 of the vacuum heat insulating material 6. Since the thickness of the trunk edge 7 is equal to the thickness of the core 11 of the vacuum heat insulating material 6, the interior materials 8a, 8b and the trunk edge 7 are in contact directly under the butting portion 9, and the interior materials 8a, 8b and the trunk edge are in contact with each other. A filling structure without a gap is formed.

  In the present embodiment, the description has been given for the wall 2 of the house. However, the embodiment of the ceiling 3 and the floor 4 is omitted in order to achieve the same effect even if the ceiling 3 and the floor 4 are replaced. .

You may choose. Moreover, the appearance quality can be improved by finishing the interior materials 8a and 8b with wallpaper.

  The body edge 7 uses a hard foam-based heat insulating material in order to enhance the overall heat insulating effect in the heat insulating reinforcing structure 5, but a rigid member such as a plywood may be selected. However, the hard foamed heat insulating material is suitable for the body edge 7 because it has heat insulating properties and rigidity required to fix the interior materials 8a and 8b.

  Further, in the present embodiment, the trunk edge 7 is arranged in the vertical direction (vertical direction or vertical direction), but may be arranged in the horizontal direction (horizontal direction or horizontal direction). Furthermore, you may arrange | position the trunk edge 7 simultaneously with the vertical direction and a horizontal direction.

  FIG. 6 shows the vacuum heat insulating material 6 used in the present embodiment. The vacuum heat insulating material 6 is basically composed of a core material 11 and a cover material 12, and the core material 11 is sealed under reduced pressure by a heat welding part 14. The core material 11 uses a porous body having a gas phase ratio of about 90%, and is sealed under reduced pressure with an outer cover material 12 in order to increase the degree of vacuum in the gas phase portion.

Examples of the core material 11 that can be used industrially include powders, foams, and fiber bodies.
A well-known material can be utilized according to the intended use and required characteristics.

  Powders are mainly composed of dry silica, wet silica, pearlite, etc., foams are open-celled bodies such as polyurethane foam, polystyrene foam, polyphenol foam, etc., and fiber bodies are glass wool, glass fiber, alumina fiber, silica Alumina fiber, silica fiber, rock wool, etc. are mentioned. However, it is preferable that the gas phase ratio is less likely to decrease due to heat generated when the outer covering materials 12 are heat-welded.

  As shown in FIG. 7, the jacket material 12 has a multilayer structure, and is composed of a heat welding layer 13 on the core material 11 side, a gas barrier layer on the intermediate layer, and a protective layer on the outermost surface layer. The heat-welded layer 13 heats and pressurizes in the vacuum space to seal the core material 11 inside the jacket material 12 under reduced pressure, and a heat-welded portion 14 is formed at the heat-pressed portion. The

  The gas barrier layer of the jacket material 12 prevents air from entering the core material 11 through the surface of the jacket material 12, and the protective layer is damaged by dust or dust on the surface of the jacket material 12, This prevents the occurrence of pinholes due to friction, bending, and piercing by the core material 11.

  The thermal conductivity of the vacuum heat insulating material 6 produced in this way is 0.0015 to 0.0040 W / m · K at an average temperature of 24 ° C., which is about 6 to about that of a rigid urethane foam that is a general-purpose heat insulating material. The heat insulation performance is 16 times.

  Although the core material 11 of the vacuum heat insulating material 6 is comprised by one used in this Embodiment, the number of the core materials 11 may be any number. There may be two or more. About the quantity of the core material 11, it is important to aim at appropriateness according to the floor plan etc. of a house.

  In addition, about a vacuum heat insulating material, it is also possible to use the vacuum heat insulating material used in Embodiment 3.

  Below, the heat insulation reinforcement | strengthening structure (heat insulation wall) 5 is explained in full detail based on FIG.

  First, the trunk edge 7 is fixed to the indoor side surface of the wall 2 by the fixing member 25. In the present embodiment, the trunk edge 7 is held by being pierced into the pillar 10. However, the fixing member 25 that fixes the trunk edge 7 may not pierce the pillar 10.

  The vacuum heat insulating material 6 is fixed to the indoor side surface of the wall 2 with an adhesive member 30 so as not to overlap the trunk edge 7 in a direction perpendicular to the wall 2. Here, a double-sided tape is used as the adhesive member 30. For fixing the vacuum heat insulating material 6, it is possible to use a member such as a nail or a screw in addition to the adhesive member 30, but the core material from the heat-welded portion 14 can maintain the vacuum of the vacuum heat insulating material 6. It must be ensured that no part pierces the side.

  At this time, the vacuum heat insulating material 6 is disposed in advance so that protrusions on the surface of the wall 2 and foreign matters attached to the surface of the wall 2 do not damage the outer cover material 12 of the core member that is in close contact with the wall 2. It is desirable to make the surface smooth.

  Here, as shown in the modification of FIG. 5, the vacuum heat insulating material 6 may be fixed by bending a portion of the vacuum heat insulating material 6 that is composed only of the jacket material 12 when viewed in cross section. In addition, the direction in which the jacket 12 is bent may be the indoor side or the outdoor side.

Next, the plurality of plate-like interior materials 8a and 8b are arranged so as to cover the vacuum heat insulating material 6 and the trunk edge 7 from the indoor side so as to be in contact with the interior side surface of the trunk edge 7, and thereby the interior material 8a. , 8b, and the interior member 8a, 8b is fixed to the trunk edge 7 by a fixing member 26 that penetrates the trunk edge 7.

  As the fixing members 25 and 26, any member that penetrates or pierces a fixing target such as a tucker, a nail, or a screw may be used.

  As described above, the house 1 according to the present embodiment has a core between the wall 2, ceiling 3, and floor 4 that form the indoor space, and the gas barrier and flexible outer covering material 12 that faces the heat welding layers 13. The material 11 is sealed under reduced pressure and is fixed to at least a part of the indoor side surface of the wall 2, the ceiling 3, or the floor 4, and contacts the indoor side surface of the cylindrical edge 7. A plurality of plate-like interior materials 8a, 8b that cover the vacuum heat insulating material 6 and the body edge 7 from the indoor side, and penetrate the interior materials 8a, 8b and penetrate at least the body edge 7. In the building (house 1) having the fixing member 26 for fixing the interior materials 8a and 8b to the trunk edge 7 which is an object to be fixed, the abutting portion 9 where the ends of the adjacent interior materials 8a and 8b are butted together. There is a trunk edge 7 on the opposite side of the interior, and the ends of adjacent interior materials 8a and 8b are abutted against each other The trunk edge 7 located on the opposite side of the butt portion 9 to the inner side of the butt portion 9 has a fixing member 26 passing through the vicinity of the butt portion 9 of one adjacent interior material 8a and the vicinity of the butt portion 9 of the other interior material 8b adjacent to each other. Both of the fixing members 26 that penetrate are pierced.

  Thereby, the wall 2 which forms the indoor space with the vacuum heat insulating material 6 and the trunk edge 7 in which the core material 11 is sealed under reduced pressure between the gas barrier property flexible outer covering material 12 facing the heat welding layers 13, Arranged on at least a part of the indoor side surface of either the ceiling 3 or the floor 4, and then, the plurality of plate-like interior materials 8 a and 8 b, the vacuum heat insulating material 6 and the trunk edge 7 are indoors The interior material 8a, 8b is fixed to an object to be fixed by a fixing member 26 which is disposed so as to be in contact with the interior side surface of the cover body edge 7 and which penetrates at least the body edge 7 through the interior materials 8a, 8b. By fixing to the edge 7), a building (house) having a heat insulating wall (heat insulating wall, heat insulating ceiling, heat insulating floor) that can be easily constructed and has good heat insulating performance without using an in-situ foam type heat insulating material 1) can be obtained, and existing walls (existing walls, existing ceilings, existing floors) are used as heat insulating walls. In this case, it is not necessary to dismantle the existing walls (existing walls, existing ceilings, existing floors), and it is possible to easily insulate the walls at a level close to the replacement of the wallpaper. The effect becomes.

  In addition, since the vacuum heat insulating material 6 has much better heat insulating performance than general-purpose heat insulating materials such as styrene foam, the thickness of the heat insulating material portion can be reduced. As a result, the heat insulating wall (heat insulating wall, heat insulating ceiling, heat insulating material) The floor can be made thinner. Moreover, when using the wall 2, the ceiling 3, and the floor 4 on which the vacuum heat insulating material 6 is disposed as an existing wall (existing wall, existing ceiling, existing floor), the insulating wall (insulating wall, insulating ceiling, insulating floor) is used. Therefore, the projecting dimension of the wall surface to the indoor side can be reduced, and the applicable range without problems is wide and practical.

  Moreover, since the building (house 1) is provided with the vacuum heat insulating material 6 on at least a part of the indoor side surface of the wall 2, the ceiling 3, or the floor 4 forming the indoor space, the heat insulating performance is excellent. Even when the fluctuation of the outside air temperature is large, the fluctuation of the room temperature can be reduced, and when the room air is cooled or heated in order to keep the room temperature at a predetermined temperature, the energy for cooling or heating the room air is small. That's it. Particularly in the case of a house, a comfortable space can be realized with a small amount of air-conditioning energy (heating and cooling costs).

The interior materials 8a and 8b are disposed so as to come into contact with the interior side surface of the trunk edge 7, and the interior edge 7 of the abutting portion 9 where the ends of the adjacent interior materials 8a and 8b abut each other is provided. There is a fixing member 26 penetrating through the vicinity of the abutting portion 9 of one adjacent interior material 8a at the barrel edge 7 located on the inner side of the abutting portion 9 where the end portions of the adjacent interior materials 8a and 8b abut each other. Since both of the fixing members 26 penetrating the vicinity of the butting portion 9 of the other interior material 8b adjacent to each other are penetrating, the interior materials 8a and 8b can be stably fixed, and the butting portion 9 of the interior materials 8a and 8b. However, even if pressed from the indoor side, no step is generated between the interior materials, and the quality of the construction structure can be ensured.

  In addition, the trunk edge 7 is disposed between the wall 2, ceiling 3, floor 4 and the interior materials 8a and 8b forming the indoor space, and is disposed between the adjacent vacuum heat insulating materials 6, and the trunk edge 7 Is arranged between the wall 2, the ceiling 3, the floor 4 and the interior materials 8a and 8b, and the fixing member 26 penetrating the interior materials 8a and 8b pierces the trunk edge 7, so that the interior materials 8a, The fixing of 8b can be made strong.

  Further, since the trunk edge 7 does not overlap the vacuum heat insulating material 6 in a direction perpendicular to any one of the wall 2, the ceiling 3, and the floor 4, the trunk edge 7 does not overlap the surface of the vacuum heat insulating material 6.

The vacuum heat insulating material 6 is basically composed of a core material 11 and a jacket material 12, and the jacket material in a portion where the core material 11 is not present between the jacket materials 12 is thermally welded to form a heat welded portion 14. It has become. The core material 11 uses a porous body having a gas phase ratio of about 90%, and is sealed under reduced pressure with an outer cover material 12 in order to increase the degree of vacuum in the gas phase portion.

  Examples of the core material 11 that can be used industrially include powders, foams, fiber bodies, and the like, and known materials can be used depending on the intended use and required characteristics.

  Powders are mainly composed of dry silica, wet silica, pearlite, etc., foams are open-celled bodies such as polyurethane foam, polystyrene foam, polyphenol foam, etc., and fiber bodies are glass wool, glass fiber, alumina fiber, silica Alumina fiber, silica fiber, rock wool, etc. are mentioned. However, it is preferable that the gas phase ratio is less likely to decrease due to heat generated when the outer covering materials 12 are heat-welded.

  As shown in FIG. 18, the jacket material 12 has a multilayer structure, and is composed of a heat welding layer 13 on the core material 11 side, a gas barrier layer on the intermediate layer, and a protective layer on the outermost surface layer. The heat-welded layer 13 heats and pressurizes in the vacuum space to seal the core material 11 inside the jacket material 12 under reduced pressure, and a heat-welded portion 14 is formed at the heat-pressed portion. The The outer cover material 12 on the front and back of the core material 11 is basically in contact with other portions than the core material 11 due to the internal / external pressure difference, and serves as a heat welded portion 14.

  The gas barrier layer of the jacket material 12 prevents air from entering the core material 11 through the surface of the jacket material 12, and the protective layer is damaged by dust or dust on the surface of the jacket material 12, This prevents the occurrence of pinholes due to friction, bending, and piercing by the core material 11.

  The thermal conductivity of the vacuum heat insulating material 6 produced in this way is 0.0015 to 0.0040 W / m · K at an average temperature of 24 ° C., which is about 6 to about that of a rigid urethane foam that is a general-purpose heat insulating material. The heat insulation performance is 16 times.

  In the present embodiment, the core material 11 of the vacuum heat insulating material 6 is composed of two, but the number of the core materials 11 may be any number. Two or more may be sufficient and the core material 11 may be comprised by one piece. About the quantity of the core material 11, it is important to aim at appropriateness according to the floor plan etc. of a house.

  Next, the manufacturing procedure of the vacuum heat insulating material 6 will be described below with reference to FIG.

  Two jacket members 12 and a core member 11 are placed in the chamber 15, the two core members 11 are positioned between the two jacket members 12, and two sheets of the heat seal bar 17 are disposed between the upper and lower heat seal bars 17. After putting the outer covering material 12 so that the outer peripheral portion is positioned, the vacuum valve 16 is opened and the chamber 15 is evacuated.

  After the inside of the chamber 15 reaches a predetermined degree of vacuum, a pair of upper and lower heat seal bars 17 that move up and down sandwich the outer cover material 12 disposed so that the heat-welded layer 13 faces the upper and lower sides of the core material 11 and heat-compress Let Then, what was obtained by opening the release valve 18 is the vacuum heat insulating material 6a shown in FIGS. In this embodiment, the two jacket materials 12 are arranged one above the other. However, the jacket material 12 may be formed in a bag shape by heat-sealing three outer peripheral portions in advance. .

As shown in FIGS. 20 and 21, the vacuum heat insulating material 6 a wraps two core materials 11 with a covering material 12, and a heat welding portion in which the covering materials 12 are thermally welded to the outer peripheral portion of the covering material 12. 14 is formed and sealed under reduced pressure. Here, the upper and lower outer cover materials 12 in the places where the core material 11 is not provided.
Will be in close contact with the internal / external pressure difference.

  After that, the vacuum heat insulating material 6a is put into a thermostatic chamber 19 as shown in FIG. 22 in order to heat-weld a place where the core material 11 is not present between the jacket materials 12 and the upper and lower jacket materials 12 are in close contact with each other. To do. The atmospheric temperature inside the thermostatic chamber 19 is set to be about 5 ° C. to 30 ° C. higher than the melting point of the heat welding layer 13 in the jacket material 12. After a predetermined time of about several minutes has passed, the material taken out is the vacuum heat insulating material 6 in the present embodiment shown in FIGS.

  Alternatively, the vacuum heat insulating material 6a is heated for a predetermined time of about several minutes using a heating device 20 that heats the vacuum heat insulating material 6a in a non-contact manner. The vacuum heat insulating material 6 can also be obtained by heat-welding the location where the workpiece 12 is in close contact.

  Here, examples of the heating means of the heating device 20 include a method using infrared rays or hot air. In FIG. 23, the heating device 20 is arranged only on one side of the vacuum heat insulating material 6a, but it may be arranged on the other side.

  The vacuum heat insulating material 6 used in the present embodiment is one in which two core materials 11 are arranged in the horizontal direction, but not limited to this, even if the core material 11 is arranged in three or more in the horizontal direction, Two or more core members 11 may be arranged in the vertical direction, or the core members 11 may be arranged in a plurality of rows and columns in the horizontal direction and the vertical direction. Moreover, although the vacuum heat insulating material 6 used by this Embodiment is one type, you may combine a multiple types of vacuum heat insulating material, or the core material 11 may combine one vacuum heat insulating material.

  Below, the heat insulation reinforcement | strengthening structure (heat insulation wall) 5 is explained in full detail based on FIG.

  The vacuum heat insulating material 6 is oriented so that the two core materials 11 are arranged in the horizontal direction (left-right direction), and one surface of the core material portion where the core material 11 is between the jacket materials 12 is a surface on the indoor side of the wall 2. The heat welded portion 14 between the two core members 11 and the heat welded portion 14 located between the two core members 11 are closely contacted with each other with a predetermined width. The outer heat welding portion 14 is bent to determine the installation position, and while holding the vacuum heat insulating material 6 by hand so as not to move, the wall 2 on the center line of the heat welding portion 14 between the core members and the outer heat welding portion 14 A portion (a central portion in the width direction of a portion in close contact with the wall 2 in the outer peripheral heat-welded portion 14) that is in close contact with the core material portion is fixed to the wall 2 by the fixing member 24.

  The vacuum heat insulating material 6 is fixed to the indoor side surface of the wall 2 that forms the indoor space by a fixing member 24 that penetrates the pillar 10 through the heat welding portion 14 and the inner surface plate 2a.

  At this time, the vacuum heat insulating material 6 is disposed in advance so that protrusions on the surface of the wall 2 and foreign matters attached to the surface of the wall 2 do not damage the outer cover material 12 of the core member that is in close contact with the wall 2. It is desirable to make the surface smooth.

  After the vacuum heat insulating material 6 has been fixed to the portion of the wall 2 forming the indoor space on the surface on the indoor side where it is desired to improve the heat insulating performance, the core material 11 is made of a foam heat insulating material and the vacuum heat insulating material 6 is sealed. The wall edge 7 having a thickness substantially equal to the thickness of the wall 2 is in close contact with the wall 2 in the heat welded portion 14 between the core members and the wall 2 in the heat welded portion 14 on the left and right outer circumferences. The barrel edge 7 is fixed to the wall 2 by a fixing member 25 which is disposed so as to be in contact with the surface on the indoor side of the portion, and penetrates the barrel edge 7, the heat-welded portion 14 and the inner surface plate 2 a and pierces the column 10. .

Next, the plurality of plate-like interior materials 8a and 8b are arranged so as to cover the vacuum heat insulating material 6 and the trunk edge 7 from the indoor side so as to be in contact with the interior side surface of the trunk edge 7, and thereby the interior material 8a. , 8b, the body edge 7, the heat welding portion 14 of the vacuum heat insulating material 6, and the inner surface plate 2a are fixed to the wall 2 by the fixing member 26 that pierces the pillar 10.

  The fixing members 24, 25, and 26 are strong in terms of strength against the portion of the wall 2 where the column 10 is present. However, the fixing members 24, 25, and 26 are inevitably struck at a location without the column 10, or partially struck at a location without the column 10. Sometimes.

  As the fixing members 24, 25, and 26, any member that penetrates and fixes a fixing target such as a tucker, a nail, or a screw may be used.

  As described above, the house 1 according to the present embodiment has a core between the wall 2, ceiling 3, and floor 4 that form the indoor space, and the gas barrier and flexible outer covering material 12 that faces the heat welding layers 13. A core between a vacuum heat insulating material 6 in which the material 11 is sealed under reduced pressure and disposed on at least a part of the indoor surface of any one of the wall 2, the ceiling 3, and the floor 4, and the jacket material 12 in the vacuum heat insulating material 6 The body edge 7 disposed so as to be in contact with a part of the indoor side surface of the heat-welded portion 14 in which the outer jacket materials 12 facing each other without the material 11 are thermally welded, and the indoor side surface of the trunk edge 7 A plurality of plate-like interior materials 8a, 8b, interior materials 8a, 8b, body edge 7, and vacuum heat insulating material 6 which are arranged so as to come into contact with each other and cover the vacuum heat insulating material 6 and the body edge 7 from the indoor side. The fixing member 26 that penetrates the heat welding portion 14 and is stuck into any one of the wall 2, the ceiling 3, and the floor 4 to fix the interior materials 8 a and 8 b. Is a building (house 1) having a trunk edge 7 on the opposite side of the abutting portion 9 where the ends of adjacent interior materials 8a and 8b are abutted to each other, and the end portions of the adjacent interior materials 8a and 8b The barrel edge 7 located on the opposite side of the abutting portion 9 to the abutting portion 9 has a butting portion 9 of the other interior material 8b adjacent to the fixing member 26 passing through the vicinity of the abutting portion 9 of the adjacent interior material 8a. Both of the fixing members 26 penetrating the vicinity are penetrating.

  As a result, the vacuum heat insulating material 6 in which the core material 11 is sealed under reduced pressure between the gas barrier and flexible outer covering material 12 facing each other with the heat-welding layers 13, the wall 2, the ceiling 3, and the floor 4 forming the indoor space. Are disposed on at least a part of the surface on the indoor side, and next, the body rim 7 is arranged so that the outer covering materials 12 facing each other without the core material 11 between the outer covering materials 12 in the vacuum heat insulating material 6 are arranged. It arrange | positions so that it may contact with a part of room | chamber interior side surface of the heat-welded part 14 heat-welded, Next, several plate-shaped interior material 8a, 8b is attached to the vacuum heat insulating material 6, the trunk edge 7, and From the interior side so as to be in contact with the interior side surface of the barrel edge 7, penetrating the interior materials 8 a, 8 b, the trunk edge 7, and the heat welding part 14 of the vacuum heat insulating material 6, and the wall 2. By fixing the interior materials 8a, 8b with a fixing member 26 that pierces either the ceiling 3 or the floor 4, an in-situ foam-type foam insulation is obtained. It is possible to obtain a building with a heat insulating wall (insulating wall, heat insulating ceiling, heat insulating floor) 5 that can be easily installed and has good heat insulating performance, and insulate the existing wall (existing wall, existing ceiling, existing floor). In the case of wall 5, there is no need to dismantle existing walls (existing walls, existing ceilings, existing floors), and it is possible to easily insulate and strengthen at a level close to wallpaper replacement. Is also very advantageous.

  In addition, since the vacuum heat insulating material 6 has much better heat insulating performance than general-purpose heat insulating materials such as styrene foam, the thickness of the heat insulating material portion can be reduced. As a result, the heat insulating wall (heat insulating wall, heat insulating ceiling, heat insulating material) Floor) 5 can be thinned. When the wall 2, ceiling 3 and floor 4 on which the vacuum heat insulating material 6 is disposed are used as existing walls (existing walls, existing ceilings, existing floors), heat insulating walls (insulating walls, heat insulating ceilings, heat insulating floors) 5 and By doing so, the protruding dimension of the wall surface toward the indoor side can be reduced, so that the applicable range without problems is wide and practical.

  Further, the fixing member 26 for fixing the interior materials 8a and 8b penetrates the heat-welded portion 14 in which the core material 11 is not provided between the outer material 12 in the vacuum heat insulating material 6 and the facing outer materials 12 are heat-welded with each other. Thus, the fixing member 26 does not cause a vacuum break in the vacuum heat insulating material 6, and the excellent heat insulating performance of the vacuum heat insulating material 6 can be maintained.

  In addition, after fixing the trunk edge 7, the thermal welding part 14 of the vacuum heat insulating material 6 can be fixed to any one of the walls 2, the ceiling 3, and the floor 4 forming the indoor space by the trunk edge 7. Therefore, the vacuum heat insulating material 6 is fixed to the indoor side surface of the wall 2, the ceiling 3, or the floor 4 that forms the indoor space before fixing the trunk edge 7 until the trunk edge 7 is fixed. Fixing means can be used, and fixing means for fixing the vacuum heat insulating material 6 before fixing the body rim 7 can be used by fixing means such that the function of fixing or bonding decreases with the passage of time. In many cases, workability can be improved and costs can be reduced depending on the selection of fixing means.

  Moreover, since the house 1 (building) of this Embodiment has arrange | positioned the vacuum heat insulating material 6 to at least one part of the indoor side surface of the wall 2, the ceiling 3, and the floor 4 which form indoor space, Excellent heat insulation performance, even when the fluctuation of the outside air temperature is large, the fluctuation of the room temperature can be reduced, and when the room air is cooled or heated in order to keep the room temperature at a predetermined temperature, the room air is cooled or heated. Requires less energy. Particularly in the case of a house, a comfortable space can be realized with a small amount of air-conditioning energy (heating and cooling costs).

  Further, the interior materials 8a and 8b are disposed so as to be in contact with the interior side surface of the trunk edge 7, and the interior edge of the butted portion 9 where the ends of the adjacent interior materials 8a and 8b are abutted with each other 7, the body edge 7 located on the opposite side of the abutting portion 9 where the end portions of the adjacent interior materials 8 a and 8 b are abutted with each other is fixed through the vicinity of the abutting portion 9 of one of the adjacent interior materials 8 a. Since both the fixing member 26 penetrating the vicinity of the butting portion 9 of the other interior material 8b adjacent to the member 26 penetrates, the interior materials 8a and 8b can be stably fixed, and the interior materials 8a and 8b are butted together. Even if the portion 9 is pressed from the indoor side, no step is generated between the interior materials 8a and 8b, and the quality of the construction structure can be ensured.

  Moreover, the vacuum heat insulating material 6 used for the house 1 of the present embodiment has a plurality (two) of core materials 11 arranged at predetermined intervals in a direction substantially perpendicular to the thickness direction. ) Is provided between the adjacent core material 11 and the core material 11 so that the outer cover materials 12 are thermally welded to each other so that each of the core materials 11 is located in an independent space. It is.

  In the vacuum heat insulating material 6 in which the plurality (two) of core materials 11 are sealed in independent spaces and the heat welding portion 14 is provided between the adjacent core materials 11, the core material 11 is one. Arrangement (positioning and fixing) becomes easier than when a plurality of vacuum insulating materials are used.

  Further, the vacuum heat insulating material 6 in which the plural (two) core materials 11 are sealed in independent spaces and the heat welding portion 14 is provided between the adjacent core materials 11 is the same size. As compared with the case where the core material 11 uses a single vacuum heat insulating material, not only the outer peripheral heat weld portion 14 but also the heat weld portion 14 between the adjacent core material 11 and the core material 11 The interior materials 8a and 8b can be fixed by the fixing member 26 penetrating the heat welding portion 14 between the adjacent core material 11 and the core material 11.

  Further, the vacuum heat insulating material 6 in which the plural (two) core materials 11 are sealed in independent spaces and the heat welding portion 14 is provided between the adjacent core materials 11 is the same size. Compared to the case where the core material 11 uses a single vacuum heat insulating material, a space in which the core material 11 is vacuum-sealed due to pinholes being formed in the outer material 12 or the outer material 12 being damaged (bag breaking). Even if the internal pressure of the pipe rises and the heat insulation performance deteriorates, the pressure in the space in which the specific core material 11 that is directly affected by pinholes and breakage (bag breakage) is sealed under reduced pressure increases and the heat insulation performance only deteriorates. Thus, the deterioration of the heat insulating performance does not spread over the entire vacuum heat insulating material, and the effect of reducing the deterioration of the heat insulating property as the vacuum heat insulating material can be obtained.

Moreover, the vacuum heat insulating material 6 used for the house 1 of this Embodiment makes the outer covering materials 12 of the part which does not have the core material 11 contact | adhered between the outer covering materials 12, and makes the covering outer covering materials 12 mutually adhere. All the outer covering materials 12 are heat-welded and all the portions of the outer covering material 12 that are in close contact with each other are heat-welded.

  The vacuum heat insulating material 6 is the vacuum heat insulating material 6 in which all the outer covering materials 12 in which the outer covering materials 12 are in close contact with each other are thermally welded, and the portion in which the outer covering materials 12 are in close contact with each other is the outer covering material 12. Since the core 11 is thermally welded to the vicinity of the portion where the core material 11 is between, the width of the heat-welded portion 14 is wider than the vacuum heat insulating material 6 which is thermally welded only between the outer jacket materials 12 of the outer peripheral portion, thereby Since the contact area between the trunk edge 7 and the vacuum heat insulating material 6 can be widened, the contact area between the trunk edge 7 and the vacuum heat insulating material 6 can be widened, and the vacuum heat insulating material 6 can be more reliably fixed by the trunk edge 7.

  Further, when the pressing force that the vacuum heat insulating material 6 receives from the trunk edge 7 is received with a wide contact area, the pressing force per unit area at the contact portion between the trunk edge 7 and the vacuum heat insulating material 6 becomes small. The contact area with the vacuum heat insulating material 6 can be widened to reduce the possibility of damage to the heat-welded portion 14 of the vacuum heat insulating material 6 due to the trunk edge 7. Since the heat welding part 14 is thermally welded to the vicinity of the part where the core material 11 is between 12, the heat welding part 14 is damaged by the contact between the trunk edge 7 and the vacuum heat insulating material 6, or the wall penetrating through the heat welding part 14 The vacuum heat insulating material 6 is fixed by the fixing member 24 that pierces any one of the ceiling 2, the ceiling 3, and the floor 4, or penetrates the wall 2, the ceiling 3, and the floor 4 through the trunk edge 7 and the heat welding portion 14. Even when the body edge 7 is fixed by the fixing member 25, the damaged portion or the through hole of the heat welded portion 14 Since there is a high possibility that the heat-welded portion 14 having a sufficient width will remain on the core material 11 side of the completed part, there is little possibility of deterioration of the heat insulating performance of the vacuum heat insulating material 6, and the heat insulating wall (insulating heat) with high reliability of the heat insulating performance It becomes the house 1 (building) which has the wall, the heat insulation ceiling, and the heat insulation floor.

  Further, since the portion where the jacket materials 12 are in close contact with each other is thermally welded to the vicinity of the portion where the core material 11 is between the jacket materials 12, the portion where the core material 11 is located between the jacket materials 12 and the body Even if the distance from the edge 7 is narrowed, there is little possibility of deterioration of the heat insulating performance of the vacuum heat insulating material 6 due to damage of the outer covering material 12, and therefore the portion where the core material 11 is between the outer covering material 12 and the trunk edge 7 is a core material portion (a portion where the core material 11 is between the jacket materials 12) which is an effective heat insulation portion of the vacuum heat insulating material 6 in the heat insulating wall (heat insulating wall, heat insulating ceiling, heat insulating floor) 5. The overall heat insulating performance of the heat insulating wall (heat insulating wall, heat insulating ceiling, heat insulating floor) 5 can be increased.

  Further, by setting the thickness of the trunk edge 7 to be equal to or greater than the thickness of the core 11 of the vacuum heat insulating material 6, the interior materials 8a and 8b and the trunk edge 7 are surely brought into contact with each other, and the butt portion of the interior materials 8a and 8b. 9 and the trunk edge 7 do not have a gap, and the stability of the interior materials 8a and 8b can be secured.

  When the thickness of the trunk edge 7 is larger than the thickness of the core 11 of the vacuum heat insulating material 6, an air layer is formed between the vacuum heat insulating material 6 and the interior materials 8a and 8b, and this air layer contributes to heat insulation, The effect of the heat insulating structure can be enhanced. In addition, since there is a gap between the vacuum heat insulating material 6 and the interior materials 8a and 8b, the portion of the vacuum heat insulating material 6 where the core material 11 is located between the jacket materials 12 is provided indoors via the interior materials 8a and 8b. Is less likely to be damaged.

  Moreover, when the thickness of the trunk | drum 7 is equivalent to the thickness of the core material 11, since the core material 11 and interior material 8a, 8b contact, it can be set as a firm laminated structure. In this case, it is also possible to apply a member having no rigidity or a thin member as the interior materials 8a and 8b.

  In the present embodiment, since the gypsum board used for the interior materials 8a and 8b has sufficient rigidity, it is firmly attached to the trunk edge 7 located on the side opposite to the interior of the butt portion 9 of the adjacent interior materials 8a and 8b. A laminated structure can be formed. Furthermore, since the gypsum board is available at low cost and has fire resistance, it can be easily constructed and the safety of the construction structure can be enhanced.

Further, the gypsum board has a sufficient thickness and rigidity even when a person or an object contacts the interior materials 8a and 8b. Therefore, the vacuum heat insulating material 6 disposed inside the gypsum board due to the impact or the like.
It is possible to prevent the bag from being broken.

  In addition, in the house 1 of the present embodiment, the vacuum heat insulating material 6 is disposed on at least a part of the indoor side surface of the wall 2, the ceiling 3, or the floor 4 that forms the indoor space. Even when the outside air temperature fluctuates greatly, the room temperature fluctuation can be reduced, and a comfortable space can be realized with less air conditioning energy (heating and cooling costs).

However, since there is a portion where the outer jacket materials 12 facing each other are not thermally welded, it is necessary to be careful in handling the vacuum heat insulating material 27 so as not to damage the portion not thermally welded, compared to the first embodiment. When driving the fixing members 24, 25, 26, care must be taken that the heat-welded portion 14 having a predetermined width remains between the through hole formed by the fixing members 24, 25, 26 and the space in which the core material 11 is sealed. .
