Description

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

  In recent years, there has been an active movement to promote energy saving by strengthening heat insulation of houses as a countermeasure against global warming, which is a global environmental problem.

  Insulation methods for homes include fiber insulation such as glass wool and rock wool between walls, ceilings, and floor joists under the floor, and foam insulation such as polystyrene board and urethane board, A method of newly installing a foam-type heat insulating material such as urethane board on the outside has become mainstream, but in order to promote further energy saving, it is desirable to apply a vacuum heat insulating material having excellent heat insulating performance.

  However, the conventional vacuum heat insulating material is processed into a bag shape by thermally welding the end portion of the gas barrier covering material having a heat-welded layer, the core material is inserted into the bag, and the opening portion of the bag under vacuum If this is considered as a panel, the entire panel constitutes one room. For this reason, when fixing the vacuum insulation material with nails or screws, the vacuum insulation material cannot be maintained in a vacuum state if it is accidentally damaged, so the insulation performance of the vacuum insulation material must be maintained. Had the problem of being unable to.

  In order to solve this problem, a heat insulating structure of a building in which a face material is attached to the outdoor side of the shaft assembly and a vacuum heat insulating material and a plurality of crosspiece members are attached to the outdoor side or the indoor side of the face material has been reported (for example, , See Patent Document 1).

  16 and 17 are a cross-sectional view and a schematic view of a heat insulating wall of a conventional building described in Patent Document 1. FIG.

  16 and 17, an airtight layer 2 made of an airtight sheet is formed on the outdoor side of the wall shafts 1a and 1b, and crosspiece members 3 and 4 that also serve as ventilating rims are attached to the outdoor side. . Further, a heat insulating layer 5 made of a vacuum heat insulating material is formed outside the airtight layer 2, and a ventilation layer 7 is formed between the heat insulating layer 5 and the exterior material 6.

In this way, the vacuum heat insulating material can be attached to the frame without using any adhesive or nails or screws, so it is possible to provide a building with a high heat insulating effect without damaging the vacuum heat insulating material. It is done.
Japanese Patent No. 4039945

  However, the standard inter-column dimensions and wall heights in Japanese houses are 910 mm and 1810 mm, respectively. However, there are few houses that are all built according to the above dimensions due to constraints such as location conditions.

  Therefore, in the structure of the above-mentioned patent document 1, since the dimension of the vacuum heat insulating material depends on the dimension between the columns, the layout of the vacuum heat insulating material is created after measuring the size of the house for each house, and then the vacuum heat insulating material Since the dimensions of the material are derived, a large number of vacuum heat insulating materials having different dimensions are required. Moreover, since it must be constructed according to the layout diagram of the vacuum heat insulating material at the time of construction, if there are many vacuum heat insulating materials having different dimensions, the vacuum heat insulating material is mixed up at the construction site. In this case, it is necessary to remove the vacuum heat insulating material that has been mistakenly constructed, and workability is reduced.

  Moreover, since the crosspiece member is attached to the shaft assembly, a heat bridge phenomenon occurs in which heat inside and outside the room moves through the shaft assembly and the crosspiece member, and the heat insulation effect is reduced.

  This invention solves the said conventional subject and aims at providing the building which implement | achieves the improvement of workability | operativity in a construction site, and the improvement of the heat insulation effect.

  In order to achieve the above object, a building according to the present invention includes a pillar that forms a building frame, a wall, a ceiling, and a floor that form an indoor space of the building, and any one of the wall, the ceiling, and the floor. A plurality of vacuum heat insulating materials arranged on at least a part of the indoor side surface, a plurality of trunk edges fixed to at least a part of the indoor side surface of any one of the wall, the ceiling, and the floor; A building having a stab prevention plate fixed to the indoor side of the trunk edge, wherein the vacuum heat insulating material is formed by sealing the core material with a gas barrier outer cover material having a heat-welded layer on the inner surface, There is no core material between the core material portion with the core material between the outer jacket materials when viewed in the thickness direction of the core material and the outer jacket material when viewed in the thickness direction of the core material. A core-less portion, and the interior side surface and the interior side surface of the trunk edge are both the core of the vacuum heat insulating material. It is obtained by placing the barrel edge to intersect with the plurality of the posts without contacting the part.

  By disposing the trunk edge so as to intersect with the plurality of columns, the dimension of the vacuum heat insulating material can be determined without depending on the dimension between the columns. Thereby, since the kind of vacuum heat insulating material from which a dimension differs is reduced, the confusion of the vacuum heat insulating material in a construction site reduces. This reduces the chances of accidentally installing the vacuum heat insulating material, thus improving workability.

  In addition, since the entire trunk edge is not fixed to the pillar, the heat bridge phenomenon in which heat inside and outside the room moves through the pillar and the trunk edge is reduced. Thereby, the heat insulation effect of a heat insulation structure improves.

  In the building of the present invention, since the types of vacuum heat insulating materials having different dimensions are reduced, the mix-up of the vacuum heat insulating materials at the construction site is reduced. This reduces the chances of accidentally installing the vacuum heat insulating material, thus improving workability. In addition, since the entire trunk edge is not fixed to the column, the heat bridge phenomenon in which heat inside and outside the room moves through the column and the trunk edge is reduced, so that the heat insulating effect of the building is improved.

  The invention of the building according to claim 1 of the present invention is any one of the pillar that forms the building frame, the wall, the ceiling, the floor, and the wall, the ceiling, and the floor that form the indoor space of the building. A plurality of vacuum heat insulating materials arranged on at least a part of the indoor side surface, a plurality of trunk edges fixed to at least a part of the indoor side surface of any one of the wall, the ceiling, and the floor; A building having a stab prevention plate fixed to the indoor side of the trunk edge, wherein the vacuum heat insulating material is formed by sealing the core material with a gas barrier outer cover material having a heat-welded layer on the inner surface, There is no core material between the core material portion with the core material between the outer jacket materials when viewed in the thickness direction of the core material and the outer jacket material when viewed in the thickness direction of the core material. A core-less portion, and both the inner-side surface and the non-interior-side surface of the trunk edge are the core portion of the vacuum heat insulating material. It is obtained by placing the barrel edge to intersect with the plurality of the posts without contacting.

  By disposing the trunk edge so as to intersect with the plurality of columns, the dimension of the vacuum heat insulating material can be determined without depending on the dimension between the columns. Thereby, since the kind of vacuum heat insulating material from which a dimension differs is reduced, the confusion of the vacuum heat insulating material in a construction site reduces. This reduces the chances of accidentally installing the vacuum heat insulating material, thus improving workability.

  In addition, since the entire trunk edge is not fixed to the pillar, the heat bridge phenomenon in which heat inside and outside the room moves through the pillar and the trunk edge is reduced. Thereby, the heat insulation effect of a building improves.

A method to do is available.

  In addition, when fixing the trunk edge to the pillar via the wall, ceiling, or floor using fixing members such as tucker, nails, screws, etc., it will be fixed if one trunk edge intersects with only one pillar. Since the barrel edge is easy to rotate around the part and the stab prevention plate fixed to the barrel edge becomes unstable, it is desirable to arrange it so as to intersect two or more columns.

  In addition, another member such as a coreless portion of the vacuum heat insulating material is interposed between the room-side surface of the wall, ceiling, or floor that forms the indoor space and the surface of the body edge opposite the room interior. In this case, the trunk edge is indirectly fixed to the indoor surface of the wall, ceiling, or floor. For this reason, fixing members such as tuckers, nails and screws penetrate the separate member so that the fixed state of the separate member does not affect the fixed state of the trunk edge, and the wall, ceiling, or floor has an indoor surface. It is desirable to fix so that it pierces.

  In addition, there is no particular designation regarding the method of fixing the vacuum heat insulating material to the indoor side surface of the wall, ceiling, or floor that forms the indoor space. Among them, there is a method of fixing the adhesive or double-sided tape to the surface inside the room, and fixing it to the room inside surface of the wall, ceiling, or floor, or the heat that opposes the part without the core material of the vacuum heat insulating material.

A method of holding the vacuum heat insulating material by the generated frictional force can be used.

  In addition, if the interior surface of the wall, ceiling, or floor that forms the interior space is made of a material that cannot be directly fixed to the vacuum heat insulating material using a tucker, nails, or screws, such as concrete or brick, the surface of concrete, etc. A method in which an anchor bolt is embedded in advance and a vacuum heat insulating material is fixed using a screw can be used.

  In addition, the state in which the trunk edge intersects with the pillar is a state in which the pillar and trunk edge intersect three-dimensionally across the walls, ceiling, and floor forming the indoor space, that is, the positional relationship of mathematical twist. Point to.

  In addition, the stab prevention plate here is installed so as to face the indoor side surface of the vacuum heat insulating material for the purpose of protecting the vacuum heat insulating material, structural plywood, particle board, gypsum board, mortar, tatami mat, It refers to new walls, ceilings, and floors made of conventionally known materials such as flooring materials.

  Next, the constituent material of a house is demonstrated.

  The ceiling is a board wall stretched to hide the upper shed or floor group in the room, and refers to structural plywood, particle board, gypsum board, mortar, concrete, and the like, similar to the wall.

  The floor is a board with a joist that is higher than the ground inside the building, and structural plywood, particle board, gypsum board, mortar, concrete, etc. can be used in the same way as the walls and ceiling.

  Also, the pillar refers to the framework that forms the building's enclosure, and refers to the pillars, beams, and joists provided on the opposite side of the walls, ceiling, and floor that form the interior space of the building. Known materials can be used.

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

  The core material forms a heat insulating part of the vacuum heat insulating material, and plays a role as a skeleton of the heat insulating part.

  The type of the core material is not particularly specified, but a porous body having a gas phase ratio of about 90%, specifically, open-cell bodies such as urethane foam, styrene foam, phenol foam, glass wool, rock wool, and alumina. Conventionally known materials such as fibers, fiber bodies such as silica alumina fibers and silica fibers, and powders such as pearlite, wet silica, and dry silica can be used.

  The jacket material plays a role of maintaining the vacuum degree of the vacuum heat insulating material, the innermost layer is a heat welding layer, and the intermediate layer has a resin film on which metal foil or metal atoms are deposited as a gas barrier layer, Each outermost layer is laminated with a surface protective layer.

  In addition, although it does not specify in particular as a heat welding layer, thermoplastic resins, such as a low density polyethylene film, a linear low density polyethylene film, a high density polyethylene film, a polypropylene film, a polyacrylonitrile film, or those mixtures are included. Can be used.

  As the gas barrier layer, a metal foil such as an aluminum foil or a copper foil, a film obtained by depositing a metal or metal oxide such as aluminum or copper on a polyethylene terephthalate film or an ethylene-vinyl alcohol copolymer, or the like can be used.

  Moreover, as a surface protective layer, conventionally well-known materials, such as a nylon film, a polyethylene terephthalate film, a polypropylene film, can be used.

  In addition, although it does not specify in particular regarding the manufacturing method of a vacuum heat insulating material, it obtained by folding back one outer covering material and heat-welding the heat welding layers located in the edge part of the opposing outer covering material. A core material is inserted into a bag-shaped jacket material, and heat-welded layers located in the opening of the bag-shaped jacket material are thermally welded under reduced pressure, or two sheets so that the heat-welded layers face each other The core material is inserted into a bag-shaped jacket material obtained by thermally welding the heat-welded layers located at the end portions of each jacket material, and the bag-like shape is formed under reduced pressure. What heat-welded the heat welding layers located near the opening part of a jacket material can be utilized.

  Moreover, the invention of the building according to claim 2 is the invention according to claim 1, in which the surface on the inner side of the trunk edge contacts at least a part of the coreless portion of the vacuum heat insulating material. .

  The structure of the building in the present invention is to fix the trunk edge on the indoor side of the vacuum heat insulating material after arranging the vacuum heat insulating material on the walls, ceiling and floor forming the indoor space. It becomes easy to recognize the arrangement position of. This prevents the vacuum insulation material from being damaged when fixing the stab prevention plate using a tucker, nail or screw, and removes the fixed stab prevention plate or trunk edge to remove the damaged vacuum insulation material. The workability is improved because the removal work is unnecessary.

  In addition, although it does not specify in particular about the method of fixing a trunk edge to a vacuum heat insulating material, it uses fixing members, such as a tucker, a nail, and a screw, and the heat-welding layers which oppose among the core material-less parts of a vacuum heat insulating material. A method of fixing the heat-welded part and body edge, which are heat-welded, to the wall, ceiling, floor, or pillar that form the interior space, or providing an adhesive or double-sided tape on the surface of the body edge opposite the room, vacuum insulation A method of fixing to a coreless portion of the material can be used.

  However, because the coreless part of the vacuum heat insulating material is interposed between the indoor side surface of the wall, ceiling, or floor that forms the indoor space, and the surface of the trunk edge opposite the indoor side, It is expected that the trunk edge is indirectly fixed to the indoor side surface of the wall, ceiling, or floor. Therefore, a fixing member such as a tucker, a nail, or a screw penetrates another member so that the shape of the coreless portion does not affect the fixing state of the trunk edge, and the indoor side surface of the wall, ceiling, or floor It is desirable to fix so that it pierces.

  Moreover, the invention of the building described in claim 3 is the invention described in claim 1, wherein the interior side surface of the trunk edge is in contact with at least a part of the coreless portion of the vacuum heat insulating material.

  The structure of the building in the present invention is different from the building invention described in claim 2 in order to fix the vacuum heat insulating material on the indoor side of the trunk edge after arranging the trunk edge on the wall, ceiling, and floor forming the indoor space. Even when the coreless portion of the vacuum heat insulating material in contact with the trunk edge is deformed, the surface of the trunk edge on the inner side of the trunk edge can be brought into close contact with the wall, ceiling, and floor. Thereby, the level | step difference which generate | occur | produces in the seam of the stab prevention plates fixed to the room inner side of the trunk edge can be suppressed, and the workability | operativity improves because the operation | work which corrects a level | step difference becomes unnecessary.

  Moreover, the method of fixing a vacuum heat insulating material to the room inner side of a trunk edge inserts a core material in a bag-shaped outer covering material, and heat welding layers located in the opening part of a bag-shaped outer covering material under pressure reduction Among the parts without core material generated in the vacuum heat insulating material heat-welded, it is easy to recognize the unwelded part where the opposing heat-welded layers are not welded, and when fixing the stab prevention plate, use a fixture such as a tucker Damage to the vacuum insulation can be prevented. This eliminates the need to remove the fixed stab prevention plate and remove the damaged vacuum heat insulating material from the trunk edge, thereby improving workability.

  In addition, although it does not specify in particular about the method of arrange | positioning a vacuum heat insulating material to a trunk edge, it is a tucker, a nail, Adhesive or double-sided tape on the interior side surface of the trunk edge or the inner surface of the vacuum heat insulating material without the core material using a fixing member such as a screw And a method of fixing the vacuum heat insulating material to the trunk edge can be used.

  Moreover, the invention of the building according to claim 4 is the invention according to claim 1, wherein the inner side surface and the inner side surface of the trunk edge are not in contact with the coreless portion of the vacuum heat insulating material. The stab prevention plate and the wall, ceiling, or floor that form the indoor space are in contact with at least a portion of the indoor surface.

  The structure of the building in the present invention is such that the interior side surface and the interior side surface of the trunk edge do not come into contact with the coreless portion of the vacuum heat insulating material, and the wall, ceiling, Since it is in contact with at least a part of any indoor surface of the floor, it becomes easy to recognize both the position of the trunk edge and the vacuum heat insulating material. This prevents damage to the vacuum insulation material that occurs when fixing the barrel edge to the walls, ceiling, or floor that forms the interior space using the tucker, nails, or screws, or fixing the stab prevention plate to the trunk edge. This eliminates the need to remove the fixed stab prevention plate and remove the damaged vacuum heat insulating material, improving workability.

  Moreover, the structure of the building in the present invention is different from the inventions described in claims 2 and 3 of the present invention, in which the coreless portion of the vacuum heat insulating material is the interior side surface of the trunk edge and the surface opposite to the interior side, Since they are not in contact with each other, even when the coreless portion of the vacuum heat insulating material is deformed, the shape of the coreless portion does not affect the fixed state of the trunk edge and the stab prevention plate. Thereby, since a level | step difference does not generate | occur | produce in the seam of the stab prevention plates fixed to the room inner side of the trunk edge, the workability | operativity at the time of fixing a stab prevention board to a trunk edge improves.

  In addition, although it does not specify in particular about the fixing method of a vacuum heat insulating material, an adhesive and a double-sided tape are provided in a core material part located in the surface inside a room inside a vacuum heat insulating material, or a core material absence part, and indoor space is made. The method of fixing to the wall, ceiling and floor to be formed, and the dimensions in the width direction of the vacuum heat insulating material in the state where the coreless portion of the vacuum heat insulating material is bent from the end of the core material to the indoor side or the non-indoor side, A method of holding the vacuum heat insulating material by the frictional force generated between the vacuum heat insulating material and the body edge can be used with substantially the same dimension between the edges.

  Moreover, the invention of the building according to claim 5 is the invention according to any one of claims 1 to 4, wherein the vacuum insulating material is in close contact with the jacket materials positioned in the coreless portion. All of the portions of the heat-welded layers are heat-welded.

  The conventional vacuum heat insulating material has a core material in a bag-shaped outer cover material obtained by folding back one outer cover material and thermally welding the heat-welding layers located at the ends of the opposite outer cover materials. Insert and heat-weld the heat-welding layers located at the opening of the bag-like outer covering material under reduced pressure, or prepare two outer covering materials so that the heat-welding layers face each other. The core material is inserted into the bag-shaped outer cover material obtained by heat-welding the heat-welding layers positioned at the ends of the material, and the heat positioned near the opening of the bag-shaped outer cover material under reduced pressure Since the welded layers are heat-welded, the coreless portion has a welded portion where the opposed heat-welded layers are welded and an unwelded portion where the opposed heat-welded layers are not welded. Was.

  If a fixing tool such as a nail, a screw, or a tucker is pierced into the unwelded portion, air enters the vacuum heat insulating material from the hole formed in the non-welded portion, so that the vacuum degree of the vacuum heat insulating material cannot be maintained. In this case, depending on the construction situation, it is necessary to remove the fixed stab prevention plate and the trunk edge and remove the vacuum heat insulating material, and workability is lowered.

  In the present invention, since the vacuum heat insulating material in which all the heat-welding layers in the portions where the outer jacket materials located in the coreless portion are in close contact with each other is used, the outer jacket materials are in close contact with each other. Since there is no unwelded portion in the portion, even when a fixture such as a nail, a screw, or a tucker is pierced, the vacuum heat insulating material can be maintained at a vacuum level.

  This eliminates the need to remove the fixed stab prevention plate and the trunk edge and remove the damaged vacuum heat insulating material, thereby improving workability.

  In addition, although it does not specify in particular about the thermal welding method of a peripheral part here, the heat welding layers pressed by atmospheric pressure after sealing a core material under reduced pressure are heated to melting | fusing point of a heat welding layer in high temperature atmosphere. A method and a method of sealing the core material immediately after heating the jacket material to the melting point of the heat-welded layer in a reduced-pressure atmosphere can be used.

  However, in the present invention, since the core material is heated at the same time as the jacket material is heated, the core material needs to have heat resistance. Therefore, a desirable core material in the present invention has heat resistance such as glass wool and rock wool having heat resistance, inorganic fiber bodies such as alumina fibers, silica alumina fibers and silica fibers, and inorganic powders such as wet silica and dry silica. Material is desirable.

  In addition, if there are multiple cores in a single vacuum insulation, multiple cores can be fixed in a single operation to fix the vacuum insulation to the body edge, further improving workability. To do.

  Moreover, the invention of the building according to claim 6 is the invention according to any one of claims 1 to 5, wherein the distance between the trunk edges separated by the vacuum heat insulating material is smaller than the distance between the columns. Is.

  Fixing the pillar and the stab prevention plate is strengthened by making the distance for fixing the stab prevention plate to the pillar via the trunk edge smaller than the distance between the pillars. For this reason, it has the effect | action which can suppress the level | step difference between the stab prevention plates which is easy to produce by installation of a vacuum heat insulating material or a trunk edge.

  This eliminates the need to adjust the driving force and tightening torque when the stab prevention plate is fixed with a nail, screw, tucker, or the like, thus improving workability.

  The invention of the building according to claim 7 is the invention according to any one of claims 1 to 6, wherein at least a part of the plurality of vacuum heat insulating materials is arranged to intersect with the pillar. .

  By arranging the vacuum insulation material so that at least a part of the plurality of vacuum insulation materials intersects with the pillars, the vacuum insulation material is interposed between the pillars and the stab prevention plate. The bridge phenomenon has the effect of further reducing.

  Thereby, the heat insulation effect of a building can further be improved.
