  In order to apply the vacuum heat insulating material 201 to a heat insulating wall of a building such as a house, it is important to realize a heat insulating structure that can prevent a vacuum break of the vacuum heat insulating material 201. Consideration should be given to the arrangement method and the arrangement position of the trunk edge 103.

  Furthermore, since the location (area) where the vacuum heat insulating material can be applied in each building differs with respect to the number of the vacuum heat insulating material 201 to be arranged, it is necessary to estimate the number of vacuum heat insulating materials to be applied for each building.

  In view of the above-mentioned problems, the present invention provides a heat insulation modification in which a vacuum heat insulating material is directly attached to the indoor side of a wall, can be easily constructed, has a good heat insulation performance, and simplifies the construction process. It aims to provide a method.

In order to achieve the above object, according to the building construction method of the present invention, a plurality of trunk edges are arranged on the indoor side of the wall forming the indoor space of the building, and a jacket is provided between the trunk edges. A vacuum heat insulating material obtained by bending a portion composed only of a material is disposed, and a foam-based heat insulating material is disposed at a place where the vacuum heat insulating material is not disposed in a space between the body edge and the body edge, A construction method for a building in which an interior material is arranged on a surface on an indoor side at an edge to form a heat insulating wall, the width direction of the vacuum heat insulating material

  Thereby, it can construct easily, heat insulation performance is favorable, and simplification of a construction process can be aimed at.

  According to the building construction method of the present invention, the floor space of the indoor space is not allocated, without allocating the vacuum heat insulating material in consideration of the components in the wall of the indoor space such as the opening and outlet portion of the indoor space and the air conditioner. Since the number of vacuum insulation materials can be determined, it is not necessary to visit the site in advance of construction to form insulation walls for each building, and to measure the number of vacuum insulation materials required for measurement, thereby speeding up the construction. I can plan.

  Moreover, in the present invention, a building 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 can be obtained without using an in-situ foam type heat insulating material. When converting a wall (existing wall, existing ceiling, existing floor) into a heat insulating wall (insulating wall, insulating ceiling, insulating floor), it is not necessary to dismantle the existing wall (existing wall, existing ceiling, existing floor), Since it is possible to easily insulate and reinforce at a level close to re-covering, an advantageous effect can be obtained in terms of construction period and construction cost.

  Moreover, the building construction method of the present invention can thin the heat insulating walls (heat insulating walls, heat insulating ceilings, heat insulating floors).

The principal part cross-section perspective view which shows the process of arrange | positioning a vacuum heat insulating material in the surface of the indoor side of the wall of the house in the embodiment Schematic cross-sectional view of conventional heat insulation wall Cross section of conventional vacuum insulation

  The construction method of the building of 1st invention arrange | positions a several trunk edge on the indoor side of the wall which forms indoor space, arrange | positions a vacuum heat insulating material between the said trunk edge, and the said trunk edge A building construction method in which an interior material is arranged on a surface on the indoor side to form a heat insulation wall, wherein a standard number of vacuum insulation materials is determined in advance with respect to a floor plan of the indoor space, and the standard arrangement number is limited The vacuum heat insulating material is disposed in the indoor space.

  Therefore, the number of vacuum heat insulating materials can be determined only for the floor space of the indoor space without allocating the vacuum heat insulating material in consideration of the components in the wall of the indoor space such as the opening and the outlet portion of the indoor space and the air conditioner. Therefore, it is not necessary to visit the site in advance of construction to form a heat insulating wall for each building, and to measure the number of required vacuum heat insulating materials, and it is uniquely vacuum only with information on the layout of the indoor space. The quantity of the heat insulating material can be determined and the construction can be speeded up.

  Moreover, since it follows the standard arrangement quantity of the vacuum heat insulating material determined according to the layout of the indoor space, anyone can easily place an order for the vacuum heat insulating material.

  When the number of vacuum heat insulating materials is insufficient on site, other heat insulating materials can be substituted. On the other hand, when the quantity of the vacuum heat insulating material becomes excessive, it may be taken away and used in another property or discarded on the spot.

  Moreover, in this invention, the building which has the heat insulation wall (heat insulation wall, heat insulation ceiling, heat insulation floor) which can be constructed easily and has favorable heat insulation performance can be obtained, and the existing wall (existing wall, existing ceiling, existing floor) can be obtained. When using insulation walls (insulation walls, insulation ceilings, insulation floors), there is no need to dismantle existing walls (existing walls, existing ceilings, existing floors), and it is easy to reinforce insulation at a level close to wallpaper replacement. Therefore, it is possible to obtain an advantageous effect in terms of construction period and construction cost.

  Moreover, the building construction method of the present invention can thin the heat insulating walls (heat insulating walls, heat insulating ceilings, heat insulating floors). If the walls, ceilings, and floors where the vacuum insulation material is to be installed are used as existing walls (existing walls, existing ceilings, existing floors), the indoor side by using heat insulating walls (insulating walls, insulating ceilings, insulating floors) Since the protruding dimension of the wall surface can be reduced, the applicable range is wide and practical without problems.

  Furthermore, the building construction method of the present invention is excellent in heat insulating performance because the vacuum heat insulating material is disposed on at least a part of the indoor side surface of the wall, ceiling, or floor forming the indoor space. Even when the fluctuation of the room temperature is large, when the room air is cooled or heated to keep the room temperature at a predetermined temperature, the energy for cooling or heating the room air can be reduced. 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).

  In the building construction method of the second invention, in particular, in the first invention, the foam-based heat insulating material is disposed at a location where the vacuum heat insulating material is not disposed in the space between the trunk edges.

  Therefore, when the predetermined number of vacuum heat insulating materials is insufficient, the foaming heat insulating material can be substituted and disposed to prevent heat insulation defects at that location.

  Moreover, by replacing with a foam-type heat insulating material at a place where the vacuum heat insulating material does not fit, it is possible to prevent a heat insulation defect at that place.

  In the construction method for a building of the third invention, in particular, in the first or second invention, the interval between the trunk edges located at both ends of the vacuum heat insulating material is constant, and the dimension in the width direction of the vacuum heat insulating material is It is substantially the same as the interval between the trunk edges.

  Therefore, by making the interval between the barrel edges constant, the dimensions in the width direction of the vacuum heat insulating material used for construction can be made uniform, and the number of vacuum heat insulating materials can be reduced. By narrowing down the variety of vacuum insulation materials, the accuracy (difference from the area of the vacuum insulation material actually applied to the workable surface) is also good for the number of vacuum insulation materials required according to the layout. .

  In addition, by narrowing down the types, it is possible to greatly reduce work mistakes such as a mistake in the vacuum insulation material of the worker at the construction site.

  Next, the constituent materials of the vacuum heat insulating material will be described in detail.

  The material used for the core material is obtained by processing a porous body having a gas phase ratio of about 90% into a sheet or plate, and industrially usable materials include foams, powders, and fiber bodies. . These can use a well-known material according to the use use and required characteristic.

  Among these, as the foam, open-cell bodies such as urethane foam, styrene foam, and phenol foam can be used. In addition, inorganic, organic, and mixtures thereof can be used as the powder, but industrially, powders mainly composed of dry silica, wet silica, pearlite, and the like can be used.

  In addition, inorganic, organic, and mixtures thereof can be used as the fibrous body, but inorganic fibers are advantageous from the viewpoint of cost and heat insulation performance. As an example of the inorganic fiber, a known material such as glass wool, glass fiber, alumina fiber, silica alumina fiber, silica fiber, rock wool, or the like can be used.

  In addition, mixtures of these foams, powders, fiber bodies and the like can also be applied.

  However, it is preferable that the core material has a thickness of about 3 to 12 mm and the gas phase ratio is less likely to be reduced by heat when the jacket materials are thermally welded together.

  The laminate film used for the jacket material is a laminate film in which the innermost layer is a heat-welded layer, the middle layer is a gas barrier layer, a metal foil or a metal vapor-deposited layer, and the outermost layer is provided with a surface protective layer Is applicable. In addition, the laminate film may be applied by combining two types of laminate films, ie, a laminate film having a metal foil and a laminate film having a metal vapor deposition layer.

  In addition, as a heat welding layer, a low density polyethylene film, a chain low density polyethylene film, a high density polyethylene film, a polypropylene film, a polyacrylonitrile film, an unstretched polyethylene terephthalate film, an ethylene-vinyl alcohol copolymer film, or those A mixture or the like can be used.

  As the surface protective layer, known materials such as nylon film, polyethylene terephthalate film, and stretched polypropylene film can be used.

However, the same components as those of the above-described embodiments will be denoted by the same reference numerals, and detailed description thereof will be omitted. Note that the present invention is not limited to these embodiments.

It is a principal part cross-sectional perspective view which shows the state which carried out.

  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. Both the fixing member 26 penetrating the vicinity of the butting portion 9 of the adjacent one of the interior materials 8a and the fixing member 26 penetrating the vicinity of the butting portion 9 of the other adjacent interior material 8b are provided on the body edge 7 located on the indoor side. 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. . The wall 2 is provided with an inner surface plate 2 a on the indoor side surface of the pillar 10 having a rectangular cross section arranged at predetermined intervals, and an outer surface plate 2 b on the outer surface of the column 10.

  In this embodiment, gypsum boards are used for the interior materials 8a and 8b, but other boards can be used as long as they have rigidity and can finish the indoor side surface of the heat-insulating and reinforcing structure (heat-insulating wall) 5. 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, 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. 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 shown in the schematic diagram of FIG. 9, after confirming the layout of the indoor space, the vacuum heat insulating material 6 is based on a correspondence table that defines the standard number of vacuum heat insulating materials 6 for each floor plan. Be transported.

  It is preferable that the vacuum heat insulating material 6 conveyed to the site is arranged with the standard arrangement number of the correspondence table as an upper limit, and the quantity as much as possible is arranged on the indoor side surface of the wall 2.

  In the correspondence table of FIG. 9, the number of two types of vacuum heat insulating materials 6 (vacuum heat insulating material A and vacuum heat insulating material B) is determined according to the layout of the indoor space. In that case, there will be no mistakes such as a mix of vacuum insulation materials at the site of the installer. Moreover, when the types of the vacuum heat insulating material 6 are three or more types, the area where the vacuum heat insulating material is arranged on the surface of the wall 2 on the indoor side can be increased, and the heat insulating effect can be effectively expressed.

  Furthermore, in the correspondence table of FIG. 9, if not only the quantity of the vacuum heat insulating material 6 but also the number of members such as the foam-based heat insulating material 31 required for the construction are determined, the members are transferred from the order to the construction site. The period can be smoothly promoted and logistics can be simplified.

  Moreover, as shown in FIG. 10, the vacuum heat insulating material 6 and the foam type heat insulating material 31 are arrange | positioned between the trunk edges 7, and the foam type heat insulating material 31 is arrange | positioned in the location where the vacuum heat insulating material 6 is not arrange | positioned. . However, the foam-based heat insulating material 31 is not necessarily disposed at a location where the vacuum heat insulating material 6 is not disposed, and may not be disposed when there is a component such as an outlet on the wall.

  Further, as shown in FIG. 5, the interval L1 between the barrel edges 7 is constant, and the dimension L2 in the width direction of the vacuum heat insulating material 6 is substantially the same as the interval L1 between the barrel edges 7. It is preferable to bend the jacket 12 of the vacuum heat insulating material 6 as in FIG.

  As described above, in the construction method of the house 1 of the present embodiment, a plurality of trunk edges 7 are arranged on the indoor side of the wall 2 forming the indoor space, and vacuum insulation is provided between the trunk edges 7 and the trunk edges 7. A construction method for a building in which a material 6 is disposed and interior materials 8a and 8b are disposed on the interior side surface of the trunk edge 7 to form a heat insulating wall, and the standard of the vacuum heat insulating material 6 with respect to the floor plan of the indoor space in advance The number of arranged sheets is determined, and the vacuum heat insulating material 6 is arranged in the indoor space with the standard number of arranged sheets as an upper limit.

  Thereby, the amount of the vacuum heat insulating material 6 is only the floor space of the indoor space without allocating the vacuum heat insulating material 6 in consideration of the components in the wall 2 of the indoor space such as the opening and the outlet portion of the indoor space and the air conditioner. Therefore, it is not necessary to visit the site in advance of the construction to form the heat insulation wall for each building, perform the measurement and estimate the quantity of the required vacuum heat insulating material 6, but only with the floor plan information of the indoor space, The quantity of the vacuum heat insulating material 6 can be determined uniquely and the construction can be speeded up.

  Moreover, since it follows the standard arrangement quantity of the vacuum heat insulating material 6 determined according to the layout of the indoor space, anyone can easily place an order for the vacuum heat insulating material 6.

  In addition, when the quantity of the vacuum heat insulating material 6 is insufficient on site, another heat insulating material can be substituted. On the other hand, when the quantity of the vacuum heat insulating material 6 becomes excessive, it may be taken away and used in another property or discarded on the spot.

  In addition, in this embodiment, a building 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 can be obtained, and an existing wall (existing wall, existing ceiling, existing floor) can be obtained. ) Is a heat insulating wall (heat insulating wall, heat insulating ceiling, heat insulating floor), it is not necessary to dismantle the existing wall (existing wall, existing ceiling, existing floor), and it is easy to reinforce heat insulation at a level close to wallpaper replacement. Since it can be carried out, it is possible to obtain an advantageous effect in terms of construction period and construction cost.

  Moreover, the building of this Embodiment can make a heat insulation wall (a heat insulation wall, a heat insulation ceiling, a heat insulation floor) thin. If the walls, ceilings, and floors where the vacuum insulation material is to be installed are used as existing walls (existing walls, existing ceilings, existing floors), the indoor side by using heat insulating walls (insulating walls, insulating ceilings, insulating floors) Since the protruding dimension of the wall surface can be reduced, the applicable range is wide and practical without problems.

  Furthermore, the building according to the present embodiment has the heat insulation performance and the outside air temperature because the vacuum heat insulating material 6 is disposed on at least a part of the indoor side surface of the wall, ceiling, or floor forming the indoor space. Even when the fluctuation of the room temperature is large, when the room air is cooled or heated to keep the room temperature at a predetermined temperature, the energy for cooling or heating the room air can be reduced. Particularly in the present embodiment, since it is the case of the house 1, a comfortable space can be realized with a small amount of air-conditioning energy (air-conditioning costs).

  Moreover, the construction method of the house 1 of this Embodiment arrange | positions the vacuum heat insulating material 6 and the foam-type heat insulating material 31 in the space between trunk edges 7, and the vacuum heat insulating material 6 in the space between trunk edges 7 is not arrange | positioned. A foam-based heat insulating material 31 is disposed at a location.

  Thereby, when the vacuum insulation material 6 of the defined quantity runs short, the heat insulation defect | deletion of the location can be prevented by replacing with the foam-type heat insulation material 31 and arrange | positioning.

A body rim 7 made of a foam-based heat insulating material disposed so as to be in contact with a part of the surface, and a vacuum heat insulating material 6 and a material rim 7 disposed so as to be in contact with the interior surface of the body rim 7. Interior materials 8a and 8b made of a plurality of plaster boards covering from the indoor side, interior materials 8a and 8b, trunk edge 7 and vacuum A building having a fixing member 26 for fixing interior material 8a pierce one of the walls 2 and the ceiling 3 and the floor 4 through the heat seal parts 14 of the heat member 6, the 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. Both the fixing member 26 penetrating the vicinity of the butting portion 9 of the adjacent one of the interior materials 8a and the fixing member 26 penetrating the vicinity of the butting portion 9 of the other adjacent interior material 8b are provided on the body edge 7 located on the indoor side. Has penetrated.

  Further, the vacuum heat insulating material 6 is configured such that two rectangular parallelepiped cores 11 are arranged at a predetermined distance from each other in a direction substantially perpendicular to the thickness direction, and each of the two cores 11 is located in an independent space. Further, between the adjacent core material 11 and the core material 11, there is provided a heat-welded portion 14 in which the jacket materials 12 are heat-welded.

  Further, the vacuum heat insulating material 6 is formed by bringing the outer covering materials 12 of the portion without the core material 11 between the outer covering materials 12 into close contact with each other, and thermally adhering the adhering outer covering materials 12 together. The outer jacket materials 12 of all the portions that are in close contact with each other are thermally welded.

  Further, the trunk edge 7 is formed between the core material 11 and the core material 11 adjacent to a part of the surface on the indoor side of the thermal welding portion 14 of the peripheral fin portion on the outer periphery of the two core materials 11 of the vacuum heat insulating material 6. The outer cover material 12 is disposed so as to be in contact with a part of the surface on the indoor side of the heat-welded portion 14 where the heat-welded members 12 are heat-welded, and the trunk edge 7 has substantially the same thickness as the core material 11 of the vacuum heat insulating material 6.

The wall 2 is provided with an inner surface plate 2 a on the indoor side surface of the pillar 10 having a rectangular cross section arranged at predetermined intervals, and an outer surface plate 2 b on the outer surface of the column 10.

  In this embodiment, gypsum boards are used for the interior materials 8a and 8b, but other boards can be used as long as they have rigidity and can finish the indoor side surface of the heat-insulating and reinforcing structure (heat-insulating wall) 5. 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.

Furthermore, you may arrange | position the trunk edge 7 simultaneously with the vertical direction and a horizontal direction.

  Even when the thickness of the trunk edge 7 is larger than the thickness of the core 11 of the vacuum heat insulating material 6, the interior materials 8 a and 8 b and the trunk edge 7 are connected to each other at the butting portion 9 as shown in FIG. A contact structure is formed immediately below, and a filling structure without a gap is formed between the interior materials 8a and 8b and the trunk edge 7.

  Therefore, in the present invention, the thickness of the trunk edge 7 is defined to be equal to or greater than the thickness of the core material 11 in the sealed state of the vacuum heat insulating material 6.

  FIG. 19 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 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. 20, 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 open 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. 22 and 23, the vacuum heat insulating material 6 a wraps two core materials 11 with an outer covering material 12, and a heat welding portion in which the outer covering materials 12 are thermally welded to the outer peripheral portion of the outer covering material 12. 14 is formed and sealed under reduced pressure. Here, the upper and lower outer cover materials 12 in a place where the core material 11 is not provided are brought into close contact with each other due to an internal / external pressure difference.

  Thereafter, the vacuum heat insulating material 6a is put into a thermostatic chamber 19 as shown in FIG. 24 in order to thermally weld a portion where the core material 11 does not exist 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. 19 and 20.

  Alternatively, the vacuum heat insulating material 6a is heated for a predetermined time of about several minutes by using a heating device 20 that heats the vacuum heat insulating material 6a in a non-contact manner as shown in FIG. 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. 25, 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.

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 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.

  Moreover, the vacuum heat insulating material 6 is based on the correspondence table | surface which defined the standard arrangement number of the vacuum heat insulating material 6 with respect to each floor space, after confirming the floor space of indoor space as shown in the schematic diagram of FIG. 9 in Embodiment 1.
