  The house 1 according to the first embodiment of the present invention has a heat insulation strengthening structure 5 with respect to the wall 2, the ceiling 3, and the floor 4 in FIG. 1. 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 indoors and outdoors is generally large, in this embodiment, the effect is higher when the outdoor side is outdoors.

  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.

  The house 1 according to the present embodiment includes a wall 2, a ceiling 3, and a floor 4 that form an indoor space, and vacuum insulation disposed on at least a part of the indoor side surface of any one of the walls 2, the ceiling 3, and the floor 4. A house 1 having a material 6, a trunk edge 7 disposed on a surface on the indoor side of the vacuum heat insulating material 6, and an interior material 8 fixed on the indoor side of the vacuum heat insulating material 6, And a gas barrier covering material 9 having a heat-welding layer 12 on the inner surface, and a plurality of core members 10 arranged at predetermined intervals in a direction substantially perpendicular to the thickness direction. The portions of the jacket material 9 that do not have the core material 10 between the jacket materials 9 are brought into close contact with each other so that each of the core materials 10 is located in a space independent from each other between the facing jacket materials 9. The jacket materials 9 that are in close contact with each other are thermally welded, and all the jacket materials 9 that are in close contact with each other are thermally welded. At least a part of the joint portion 11 made of the covering material 9 between the core members 10 is fixed by a fixing member 14 so as to be in contact with any one of the walls 2, the ceiling 3, and the floor 4 on the indoor side. On the surface 11, the surface of the trunk edge 7 on the side opposite to the room is disposed.

  Further, the body member 7 is penetrated by the fixing member 16 and the heat-welded portion 13 in the joint portion 11 so as to be against the indoor side surface of the wall 2, the ceiling 3, or the floor 4 forming the indoor space. The edge 7 is fixed, and the interior member 8, the trunk edge 7, and the heat welded portion 13 in the joint portion 11 are penetrated by the fixing member 17, and any one of the wall 2, the ceiling 3, and the floor 4 forming an indoor space. The interior material 8 is fixed to the inner surface.

  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. . The wall 2 is provided with an inner surface plate 2 a on the indoor side surface of the pillar 15 having a rectangular cross section arranged at predetermined intervals, and an outer surface plate 2 b on the outer surface of the column 15.

  In this embodiment, gypsum board is used for the interior material 8, but other boards are selected as long as they have rigidity and can finish the indoor side surface of the heat-insulating and reinforcing structure (heat-insulating wall) 5. It doesn't matter. In addition, the appearance quality can be improved by finishing the interior material 8 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 plywood may be selected. However, since the hard foam heat insulating material has heat insulating properties and rigidity required to fix the interior material 8, it is suitable for the trunk edge 7.

  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.

  The vacuum heat insulating material 6 basically includes an outer cover material 9 and a core material 10. The core material 10 uses a porous body having a gas phase ratio of about 90%, and is sealed under reduced pressure with a jacket material 9 in order to increase the degree of vacuum in the gas phase portion. Here, a portion constituted by the covering material 9 between the adjacent core members 10 is referred to as a joint portion 11.

  Examples of the core material 10 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.

  As shown in FIG. 4, the jacket material 9 has a multilayer structure, and is composed of a heat-welded layer 12 on the core material 10 side, a gas barrier layer, a protective layer, and the like. The heat-welding layer 12 heats and pressurizes in a vacuum space to seal the core material 10 inside the outer covering material 9 under reduced pressure, and the outer covering materials 9 facing each other with the heat-welding layers 12 facing each other. A heat-welded portion 13 is formed on the outer cover material 9 at the place where it is in close contact and heated and pressed. The jacket material 9 on the front and back sides of the core material 10 is basically in contact with other portions than the core material 10 due to the internal / external pressure difference, and serves as a heat welded portion 13. Therefore, the joint 11 of the vacuum heat insulating material 6 in the present embodiment is thermally welded.

  The gas barrier layer of the jacket material 9 prevents air from entering the core material 10 through the surface of the jacket material 9, and the protective layer is damaged by dust or dust on the surface of the jacket material 9, This prevents pinholes from being generated by friction, bending, and piercing by the core material 10.

  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 10 is composed of two, but may be composed of more core materials 10 than that.

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

  After putting the jacket material 9 and the core material 10 into the chamber 18, the vacuum valve 19 is opened and evacuation is performed. After the inside of the chamber 18 reaches a predetermined degree of vacuum, the outer cover material 9 disposed so that the heat-welding layer 12 faces the upper and lower sides of the core material 10 is sandwiched between the upper and lower surfaces of the core material 10 and heated and compressed. Then, what was obtained by opening the open valve 21 is the vacuum heat insulating material 6a. In addition, although the two jacket materials 9 are arrange | positioned up and down, you may form in the bag shape.

  As shown in FIGS. 6 and 7, the vacuum heat insulating material 6 a wraps the core material 10 with an outer cover material 9, and a heat-welded portion 13 is formed and sealed under reduced pressure. Here, the upper and lower outer cover materials 9 in a place where the core material 10 is not provided are brought into close contact with each other due to an internal / external pressure difference.

  The joint portion 11 of the vacuum heat insulating material 6 a thus manufactured is formed around the middle portion of the thickness of the core material 10 when viewed from the lateral direction of the core material 10.

  Thereafter, the vacuum heat insulating material 6a is put into a thermostatic chamber 22 as shown in FIG. 8 in order to thermally weld a portion where the core material 10 is not present and the upper and lower jacket materials 9 are in close contact. The atmospheric temperature inside the thermostat 22 is set to be about 5 ° C. to 30 ° C. higher than the melting point of the heat welding layer 12 in the jacket material 9. After a predetermined time of about several minutes has passed, what is 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 23 as shown in FIG. 9, and the portions where the core material 10 is not present and the upper and lower jacket materials 9 are in close contact are thermally welded. Thus, the vacuum heat insulating material 6 can be obtained.

  Here, examples of the heating means of the heating device 23 include a method using infrared rays or warm air. In FIG. 9, the heating device 23 is arranged only on one side of the vacuum heat insulating material 6 a, but it may be arranged on the other side.

  The heat insulation strengthening structure 5 will be described in detail below.

  The vacuum heat insulating material 6 is fixed to the wall 2 by hitting the pillar 15 using the fixing member 14 so that the joint portion 11 is in contact with the wall 2 as in the construction procedure shown in FIGS. . Here, the fixing member 14 may be struck to a place where the column 15 is not provided.

  Note that the fixing member 14 is applied in a portion where the core material 10 is not provided, that is, in the heat welding portion 13, and the vacuum breakage of the vacuum heat insulating material 6 does not occur.

  The fixing member 14 may be any member that penetrates and fixes a fixing target such as a tucker, a nail, or a screw.

  In FIG. 10, after fixing member 14 is constructed from one end portion of vacuum heat insulating material 6, fixing member 14 is constructed in the order of joint portion 11 and the other end portion, and in FIG. After the fixing member 14 is constructed from 11, the fixing member 14 is constructed at both ends.

  10 and 11, the joint 11 of the vacuum heat insulating material 6 can be fixed so as to be surely in contact with the wall 2. However, as shown in the construction procedure illustrated in FIG. After the construction, the fixing member 14 is constructed on the joint portion 11, and the joint portion 11 does not have a sufficient length and may not be able to contact the wall 2. In order to avoid such a state, it is necessary to adjust the interval between the adjacent core members 10 to be short enough to allow the joint 11 to contact the wall 2.

  As shown in FIGS. 13 and 14, the trunk edge 7 is disposed at a place where the core material 10 including the joint portion 11 on the indoor surface of the vacuum heat insulating material 6 is absent, and the vacuum heat insulating material 6 is fixed by the fixing member 16 there. It is fixed to the wall 2 through a portion where the core material 10 is not present. Here, since the vacuum heat insulating material 6 is heat-welded at a place where the core material 10 is not provided, the vacuum heat insulating material 6 is not broken even if the fixing member 16 is installed.

  The fixing member 16 may be any member that penetrates a fixing target such as a tucker, a nail, or a screw and has a sufficient length to fix the trunk edge 7 to the wall 2.

  Further, as shown in FIG. 14, the thickness of the trunk edge 7 is equivalent to the thickness of the core material 10 of the vacuum heat insulating material 6, and the same surface is formed on the inner surface of the trunk edge 7 and the core material 10. Yes.

  Furthermore, since the trunk edge 7 is disposed on the joint portion 11, it goes without saying that the width dimension of the trunk edge 7 is smaller than that of the joint portion 11.

  When the joint portion 11 of the vacuum heat insulating material 6 has no margin and cannot contact the wall 2, the trunk edge 7 disposed on the joint portion 11 contacts the wall 2 as shown in FIG. 15. Can not be achieved, and since it is arranged in the hollow, it is extremely unstable. Furthermore, the same plane cannot be formed on the interior side surfaces of the trunk edge 7 and the core member 10, which is not suitable as a construction structure.

  As shown in FIGS. 16 and 17, the interior material 8 is arranged with the interior-side surfaces of the core material 10 and the trunk edge 7 of the vacuum heat insulating material 6 as contact points. The interior material 8 is fixed to the wall 2 by the fixing member 17 via the portion of the vacuum heat insulating material 6 without the core material 10 and the trunk edge 7. Here, since the vacuum heat insulating material 6 is heat-welded at a portion where the core material 10 is not provided, the vacuum heat insulating material 6 is not broken even if the fixing member 17 is installed.

  The fixing member 17 may be anything that penetrates a fixing target such as a tucker, a nail, or a screw and has a sufficient length to fix the interior material 8 to the wall 2.

  As mentioned above, in this Embodiment, since the joint part 11 of the vacuum heat insulating material 6 contact | connects the wall 2, the fixation of the trunk edge 7 on the joint part 11 can be ensured.

  Further, in the vacuum insulation material 6, the outer cover material 9 on the front and back of the core material 10 is basically in contact with portions other than the core material 10 to form a heat-welded portion 13, and the joint portion 11 is also heat-welded. Yes.

  Therefore, even when the fixing members 14, 16, and 17 are fixed through the joint portion 11, a vacuum breakage of the vacuum heat insulating material 6 may occur regardless of where the fixing members 14, 16, and 17 are driven. Since there is not, construction can be made easy.

  Moreover, the trunk edge 7 penetrates the joint portion 11 by the fixing member 16 and is fixed to the wall 2, so that reliable construction is realized. When the joint portion 11 has a wrinkle portion (not shown) that is a non-smooth surface, the warp portion can be eliminated by pressing with the trunk edge 7.

  Moreover, since the interior material 8 presses the trunk edge 7 and the joint portion 11 from the indoor side, the joint portion 7 is securely fixed so as to be in contact with the wall 2, and a wrinkle portion that is a non-smooth surface is formed on the joint portion 11. In some cases, it is possible to eliminate the wrinkled portion by pressing through the trunk edge 7, maintain the smoothness on the surface of the interior material 8 after the completion of construction, and ensure the construction quality.

  As described above, the house 1 according to the present embodiment is arranged on at least a part of the wall 2, the ceiling 3, the floor 4, and any of the walls 2, the ceiling 3, and the floor 4 on the indoor side. A house 1 having a vacuum insulating material 6 made, a body edge 7 disposed on a surface of the vacuum heat insulating material 6 on the indoor side, and an interior material 8 fixed on the indoor side of the vacuum heat insulating material 6. The heat insulating material 6 includes a gas barrier outer covering material 9 having a heat welding layer 12 on the inner surface, and a plurality of core materials 10 arranged at predetermined intervals in a direction substantially perpendicular to the thickness direction. The covering materials 9 in a portion where the core material 10 does not exist between the covering materials 9 so that each of the core materials 10 is positioned in a space independent from each other between the covering materials 9 facing each other of the layers 12. The outer cover materials 9 that are in close contact with each other are thermally welded to each other. The fixing member 14 is used to fix at least a part of the joint portion 11 formed by the covering material 9 between the core members 10 so as to be in contact with any of the walls 2, the ceiling 3, and the floor 4 on the indoor side. In addition, the surface of the body edge 7 on the side opposite to the room interior is disposed on the joint 11, and the joint 11 of the vacuum heat insulating material 6 is fixed so as to contact the wall 2, the ceiling 3, and the floor 4. Therefore, it is possible to ensure the fixation of the trunk edge 7 on the joint portion 11.

  Moreover, since the vacuum heat insulating material 6 is comprised with the core material 10 in the space where each mutually became independent, even if a vacuum breakage arises in one core material 10, the vacuum degree of the other core materials 10 is maintained. Since it can do, the deterioration of the heat insulation performance as the whole vacuum heat insulating material 6 can be suppressed to the minimum.

  Moreover, since the vacuum heat insulating material 6 excellent in heat insulation performance is applied, the heat insulation effect can be exhibited without reducing the room volume.

  Further, the body member 7 is penetrated by the fixing member 16 and the heat-welded portion 13 in the joint portion 11 so as to be against the indoor side surface of the wall 2, the ceiling 3, or the floor 4 forming the indoor space. The edge 7 is fixed, and the trunk edge 7 is securely fixed to the wall 2, the ceiling 3, and the floor 4 by the fixing member 16. At this time, when the joint portion 11 has a wrinkle portion that is a non-smooth surface, the warp portion can be eliminated by pressing with the trunk edge 7.

  Further, the interior member 8, the trunk edge 7, and the heat welded portion 13 in the joint portion 11 are penetrated by the fixing member 17, so that the wall 2, the ceiling 3, or the floor 4 that forms the indoor space is formed on the indoor surface. On the other hand, since the interior material 8 is fixed and the interior material 8 presses the trunk edge 7 and the joint portion 11 from the indoor side, the joint portion 11 is securely fixed so as to contact the wall 2, the ceiling 3, and the floor 4. At the same time, when the joint portion 11 has a wrinkle portion that is a non-smooth surface, the wrinkle portion is eliminated by pressing through the trunk edge 7 to maintain the smoothness of the surface of the interior material 8 after completion of construction. The construction quality can be ensured.

  The vacuum heat insulating material 24 is generally processed using the vacuum heat insulating material 6a produced in the chamber 18 described in the first embodiment. The vacuum heat insulating material 24 is obtained by heat welding the core material 10 of the vacuum heat insulating material 6a with a heat seal bar or the like so that the core material 10 is divided by the heat welding portion 13a.

  The vacuum heat insulating material 24 manufactured in this way has the heat welded portion 13a formed at the joint portion 25, and the heat welded portion 13a is fixed to bring the joint portion 25 into contact with the wall 2 as shown in FIG. It is fixed by passing through the member 14. In addition, the vacuum heat insulating material 24 is fixed through the heat welding portion 13 at locations other than the joint portion 25.

  The trunk edge 7 disposed on the indoor side of the vacuum heat insulating material 24 is also fixed to the wall 2 by the fixing member 16 through the heat welding parts 13 and 13a as shown in FIG.

  Further, the interior material 8 constructed from above the vacuum heat insulating material 24 and the trunk edge 7 is also fixed to the wall 2 by the fixing member 17 through the heat welding parts 13 and 13a as shown in FIG.

  As described above, in the present embodiment, the joint portion 25 of the vacuum heat insulating material 24 is in contact with the wall 2, so that the trunk edge 7 can be reliably fixed on the joint portion 25.

  In addition, since the vacuum heat insulating material 24 has a plurality of core materials 10 that are sealed under reduced pressure so that each of them is located in an independent space, even if the core material 10 is accidentally damaged to cause a vacuum break, the core material 10 Only the heat insulation performance is deteriorated, and the deterioration of the heat insulation performance of the vacuum heat insulating material 24 as a whole can be suppressed to a minimum.

  Furthermore, since the heat welding part 13a is provided in the joint part 25 so as to isolate the core material 10, the body edge 7 and the interior material 8 arranged on the indoor side surface of the joint part 25 are replaced with the heat welding part 13a. By fixing to the wall 2 via, it becomes possible to prevent the vacuum breakage of the vacuum heat insulating material 24.

  The house in the present invention is to construct a vacuum heat insulating material having a plurality of cores on the walls, ceilings, and floors on the indoor side, as well as to enhance the heat insulating effect of the house, assured construction In addition, a stable heat insulating structure can be realized.

  The housing of the present invention is intended for new construction and existing construction, and when existing housing is targeted, heat insulation reform is performed, and simple and reliable construction can be realized.

  Further, the present invention can be applied not only to the structure in which the vacuum heat insulating material is disposed on the indoor side surface of the wall, ceiling, and floor, but also to the structure in which the vacuum heat insulating material is disposed on the outdoor side.
