Description

  The present invention relates to an interior building material with a heat insulating material.

  As a conventional heat insulation method for a house, a method for filling a wall with a heat insulating material or a heat insulation method for an outer wall for heat insulation from the outside of a housing body is known.

  In addition, glass wool is generally used as the heat insulating material used in the conventional heat insulating method, but it is also known from Patent Document 1 that a vacuum heat insulating material having better heat insulating properties than this glass wool is used.

  However, in order to carry out insulation renovation work on existing houses using the conventional insulation method described above, a large-scale work is required to build a scaffolding for the entire house, which increases costs and increases the construction period. When the scaffold cannot be assembled, it is difficult to implement the conventional heat insulation method.

  Therefore, in recent years, a lining heat insulation method has been proposed in which the vacuum heat insulating material and the surface material are sequentially applied from the indoor side of the house, taking advantage of the vacuum heat insulating material that has excellent heat insulating properties and can be thinned.

  This lining thermal insulation method can obtain high thermal insulation without narrowing the indoor space by using a thin vacuum thermal insulation material, and further, it can be constructed from the indoor side compared to the above general thermal insulation method. Therefore, it is possible to reduce both cost and construction period without involving large-scale construction such as building a scaffold.

  However, the installation work for the vacuum insulation material and the installation work for the surface material are required separately, and the installation of the vacuum insulation material at the site construction results in a difference in the installation area of the vacuum insulation material depending on the skill level of the operator. There is a problem that the heat insulation performance varies.

  In addition, since the vacuum insulation is handled and mounted alone in a bare state, the vacuum insulation is damaged during handling and the vacuum is broken, and the insulation performance is extremely lowered, making it meaningless as an insulation. There is a possibility of disappearing.

  The present invention was invented in view of the above points, and can be used for a lining insulation method from the indoor side, can be reduced in construction, can suppress variations in thermal insulation performance due to the technical level of the operator, and during construction It is in providing the interior building material with a heat insulating material excellent in the heat insulating property that a vacuum heat insulating material is hard to be damaged.

The interior building material with a heat insulating material of the present invention includes a front surface material and a back surface material, a vacuum heat insulating material interposed between the front surface material and the back surface material, and fixed to the back surface of the front surface material, and an outer end of the front surface material. And a space holding member provided between the outer end portion of the back surface material, and an elastic seal portion is provided on the outer surface of the space holding member .

  Further, it is preferable that the surface material is composed of a single layer or a plurality of layers and has at least a semi-incombustible material layer.

  Moreover, it is preferable that the said surface material has a humidity control function.

  Since the present invention constitutes an interior building material with a heat insulating material by adhering a vacuum heat insulating material to the back surface of the surface material, the vacuum heat insulating material and the surface material can be obtained only by constructing the interior building material with the heat insulating material from the indoor side. It can be installed at the same time, and the construction can be saved.

  In addition, since the vacuum heat insulating material is fixed to the back surface of the surface material, it is not necessary to install the vacuum heat insulating material alone on site, and variations in heat insulating performance due to the technical level of the operator can be suppressed.

  In addition, since the vacuum heat insulating material is fixed to the back surface of the surface material, the vacuum heat insulating material is protected by the surface material, and the vacuum heat insulating material is hardly damaged at the time of handling and construction, and the heat insulating performance is extremely high. It can control that it falls.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The interior building material 1 with a heat insulating material of the present invention is configured by adhering a vacuum heat insulating material 3 to the back surface of a surface material 2.

  The surface material 2 is constituted by a face plate, and the thickness of the face plate is preferably 2 to 15 mm. The surface material 2 is made of a wooden board, a fiber board, an inorganic board, or a board made of other materials, and is formed by laminating and integrating a single layer or an arbitrary material.

  FIG. 1 shows an example in which the surface material 2 is composed of a non-combustible surface material 2A made of a semi-incombustible material. As the non-combustible surface material 2A, for example, a semi-incombustible material such as a gypsum board having a thickness of 9 mm or more can be used.

Moreover, FIG. 2 is the example which comprised the surface material 2 with the humidity control surface material 2B which has a humidity control function. As a humidity control material used for the humidity control surface material 2B, any material having a humidity control function for absorbing and releasing moisture according to humidity may be used. Examples thereof include diatomaceous earth and B-type silica gel. As the humidity control surface material 2B, any material that satisfies the usability as the surface material 2 having the humidity control function may be used. For example, a board formed of the humidity control material or a base material (inorganic board, wood board) , Fiberboard, etc.) may be formed by laminating a layer of the humidity conditioning material.

  FIG. 3 shows an example in which the surface material 2 is composed of a low heat capacity surface material 2C having a lower heat capacity than a 9 mm thick gypsum board which is a general surface material. The low heat capacity surface material 2C only needs to have a heat capacity lower than that of a 9 mm thick gypsum board. For example, when using a gypsum board, the heat capacity is made lower than that of a normal 9 mm thick gypsum board. There is no particular limitation.

  FIG. 4 shows an example in which a plurality of layers are laminated as the surface material 2. In this example, a three-layer structure in which three layers of a semi-incombustible material layer 2a such as a plaster board, a humidity control layer 2b made of a humidity control material, and a highly rigid layer 2c such as a kenaf board are laminated and integrated. It has become.

The surface material 2 having a three-layer structure has, for example, a thickness of 15 mm or less and a thermal conductivity of 0.55 W / m ² K or less, and is generally ½ or less of a 9.5 mm thick gypsum board generally used as the surface material 2. The surface material 2 of the low heat capacity which became the heat capacity of is comprised. Therefore, this embodiment is a surface material 2 having quasi-incombustible performance and humidity control function and having a low heat capacity.

  The vacuum heat insulating material 3 interposes a core material between the front and back jacket sheets having gas barrier properties, and heat-seals the front and back jacket sheets so as to surround the core material to form a space in which the core material is disposed. In addition, the space is sealed under reduced pressure. In the attached drawings, reference numeral 3b denotes a heat seal portion obtained by heat sealing the front and back cover sheets.

  Here, as shown in FIG. 5, the vacuum heat insulating material 3 includes a plurality of core members interposed between the front and back jacket sheets, and a plurality of vacuum-sealed cells 3a each having a core member independently provided therein. It may be made up of.

  The vacuum heat insulating material 3 is fixed to the back surface of the surface material 2 by an arbitrary fixing means. For fixing, for example, it is fixed by using a general double-sided tape or adhesive used for construction applications, or the heat seal portion 3b of the outer cover sheet of the vacuum heat insulating material 3 is fixed by a tacker or the like. Also good.

  In the embodiment shown in FIG. 4, the semi-incombustible material layer 2a such as gypsum board is the front surface, and the highly rigid layer 2c such as kenaf board is the back surface. 3 is fixed.

  Since the vacuum heat insulating material 3 has extremely high heat insulating performance compared to glass wool or the like, sufficient heat insulating performance can be obtained even if the thickness is reduced. Therefore, it is optimal as a heat insulating material used for the lining heat insulating method from the indoor side, and a thickness of about 2 to 10 mm can be used. The total thickness of the surface material 2 and the vacuum heat insulating material 3 is set to a thickness that does not impair the indoor space.

  The interior building material 1 with a heat insulating material of each embodiment as described above can be installed by abutting the interior building material 1 with a heat insulating material against the wall base from the indoor side by using a nailing or other attachment means when performing heat insulation work of a house. Install.

  In this case, for example, when mounting by nailing, the nailing is performed while avoiding the vacuum sealed portion where the core of the vacuum heat insulating material 3 is disposed.

In any of the above-described interior building materials 1 with a heat insulating material, a spacing member 5 such as a crosspiece or a columnar member may be attached to the back surface side of the surface material 2 as shown in FIG. Thus, by providing the space | interval holding member 5, when attaching the interior building material 1 with a heat insulating material, it can avoid applying force to the vacuum heat insulating material 3, and can reduce the risk of the vacuum heat insulating material 3 being damaged. The spacing member 5 is preferably made of a wood material that can be nailed. In this case, the interior building material 1 with a heat insulating material is nailed so as to penetrate the spacing member 5 from the indoor side with respect to the wall base. By doing so, the interior building material 1 with a heat insulating material can be mounted and installed on the wall base.

  Since the interior building material 1 with a heat insulating material of any of the above embodiments is configured by fixing the vacuum heat insulating material 3 to the back surface of the surface material 2, the vacuum heat insulation can be achieved only by constructing the interior building material 1 with a heat insulating material from the indoor side. The material 3 and the surface material 2 can be attached at the same time, and the construction can be saved.

  And since the vacuum heat insulating material 3 with high heat insulation is fixed to the back surface of the surface material 2, the heat insulating performance in the room is improved, and the amount of heat required for raising or lowering the temperature to the set temperature of the air conditioning can be reduced. In addition, energy saving is high, and the time response speed such as room temperature becomes fast.

  In addition, since the vacuum heat insulating material 3 is fixed to the back surface of the surface material 2, it is not necessary to install the vacuum heat insulating material 3 alone at the site, and variations in the heat insulating performance due to the technical level of the workers at the site can be suppressed. .

  Further, since the vacuum heat insulating material 3 is fixed to the back surface of the surface material 2, the vacuum heat insulating material 3 is protected by the surface material 2, and the vacuum heat insulating material 3 is hardly damaged during handling and construction. It is possible to suppress the phenomenon that the heat insulating material 3 is broken and the heat insulating performance is extremely lowered.

  As shown in FIGS. 1 and 4, the surface material 2 composed of one layer or a plurality of layers and having at least a quasi-incombustible material layer satisfies the regulations due to interior restrictions. The scope of work can be expanded.

  In addition, in the case where the surface material has a humidity control function as in the embodiment shown in FIGS. 2 and 4, the indoor air is prevented from becoming highly humid during heating, and condensation is less likely to occur. Can do. Further, when the indoor air is dry, the moisture absorbed when the air was at a high humidity before that time can be released to moderate the drying of the indoor air.

  In each of the embodiments shown in FIGS. 1 to 6, the back material 4 may be attached as shown in FIGS.

  That is, the vacuum heat insulating material 3 is interposed between the plate-shaped surface material 2 and the plate-shaped back surface material 4, and the surface and the back surface of the vacuum heat insulating material 3 are fixed to the surface material 2 and the back surface material 4, respectively, by any fixing means. . At the time of fixing, it may be fixed using a general double-sided tape or adhesive used for construction applications, or the heat seal portion 3b of the outer cover sheet of the vacuum heat insulating material 3 may be fixed by a tucker or the like. .

  Here, in the embodiment of FIG. 8, the back surface material 4 is also fixed to the spacing member 5.

  Although the wood panel can be illustrated as the back material 4, it is not specifically limited.

  In the case where the vacuum heat insulating material 3 is divided into a plurality of cells 3 a as shown in FIG. 9, a columnar member 7 that penetrates the heat seal portion 3 b is provided to constitute the interval holding member 5, and both ends of the columnar member 7 are arranged. The portions may be fixed to the surface material 2 and the back surface material 4, respectively.

As in the above examples, by constructing the interior building material 1 with the heat insulating material by interposing the vacuum heat insulating material 3 between the surface material 2 and the back surface material 4, the surface side and the back surface side of the vacuum heat insulating material 3 are the surface materials, respectively. Since it is protected by 2 and the back material 4, the breakage of the vacuum heat insulating material 3 can be further suppressed during handling and construction.

  By the way, when heat insulation work is performed to attach the interior building material 1 with a heat insulating material to the wall base, water vapor generated in the room or the adjacent room penetrates into the interior building material 1 with the heat insulating material or between the wall base and the interior with the heat insulating material. Condensation may occur in the interior of the building material 1 or on the wall base, and mold or rot may occur.

  Therefore, it is preferable to provide moisture-proof means for preventing moisture permeation from the front and back surfaces of the interior building material 1 with a heat insulating material.

  10 to 14 show examples of moisture-proof means.

  FIG. 10 shows an example in which a moisture-proof sheet 8 as moisture-proof means is sandwiched and fixed between one or both of the surface material 2 and the vacuum heat insulating material 3 and between the back material 4 and the vacuum heat insulating material 3.

  Examples of the moisture-proof sheet 8 include a polyethylene sheet and an aluminum pressure-bonded film, but are not particularly limited as long as the sheet has moisture-proof performance.

  In this way, the moisture-proof sheet 8 as a moisture-proof means is interposed between the surface material 2 and the vacuum heat-insulating material 3, between the back-surface material 4 and the vacuum heat-insulating material 3, or both. The invasion of water vapor from the front and back surfaces of the attached interior building material 1 can be suppressed.

  In addition, in embodiment of FIG. 10, although the interior building material 1 with a heat insulating material which provided the back material 4 is taken as an example, in the interior building material 1 with a heat insulating material which does not provide the back material 4, the surface material 2 and the vacuum heat insulating material 3 of FIG. A moisture-proof sheet 8 may be interposed therebetween.

  Next, in the embodiment shown in FIG. 11 and FIG. 12, in the interior building material 1 with a heat insulating material having the surface material 2 and the back material 4, the distance provided between the outer end portion of the surface material 2 and the outer end portion of the back material 4. The example which has provided the sealing part 9 which has elasticity in the outer surface of the holding member 5 is shown. The seal portion 9 is provided along four or two sides of the interior building material 1 with a heat insulating material.

  The elastic seal portion 9 is made of a hollow elastic material having a hollow inside as shown in FIG. 11 (a) or a fin-like elastic material as shown in FIG. 12 (a). Can do.

  And as shown to FIG.11 (b), FIG.12 (b), the space | interval holding member of the interior building material 1 with an adjacent heat insulating material is provided with the sealing part 9 which has the elasticity provided in the outer surface of one interior building material 1 with a heat insulating material. 5 is elastically pressed against the outer surface. As a result, the seal portion 9 is elastically deformed to be in close contact with the outer surface of the spacing member 5 of the adjacent interior building material 1 with a heat insulating material, filling a gap between the adjacent interior building materials 1 with a heat insulating material, and adjacent interiors with a heat insulating material. Water vapor can be prevented from entering through the gaps between the building materials 1.

  FIG. 13 shows still another embodiment. In the present embodiment, the interval holding member 5 provided between the outer end portion of the surface material 2 and the outer end portion of the back surface member 4 is constituted by an elastic interval holding member 5a having elasticity. The elastic spacing member 5a is provided along four or two sides of the interior building material 1 with a heat insulating material. The elastic spacing member 5a is formed of, for example, an elastic rubber mainly composed of an organic polymer such as natural rubber or synthetic rubber, but is not limited thereto, and may be formed of another elastic material. .

This embodiment suppresses that water vapor | steam penetrate | invades from the clearance gap between the adjacent interior building materials 1 with a heat insulating material by constructing so that the elastic space | interval holding members 5a of the adjacent interior building materials 1 with a heat insulating material may contact elastically. be able to.

  Moreover, in this embodiment, since the surface material 2 and the back surface material 4 are joined by the elastic space | interval holding member 5a which has elasticity, generation | occurrence | production of the internal stress by the difference in expansion | extension of the surface material 2 and the back surface material 4 is suppressed. be able to.

  14 (a) and 14 (b) show still another embodiment. The interior building material 1 with a heat insulating material constituted by fixing the vacuum heat insulating material 3 between the surface material 2 and the back surface material 4 is a surface material in a portion where the heat seal portion 3b portion of the vacuum heat insulating material 3 is located. A gap is generated between 2 and the back material 4. The embodiment of FIG. 14 shows an example in which the gap portion where the heat seal portion 3b is located is filled with a thermoplastic hot melt adhesive having elasticity after curing to constitute the elastic spacing member 5a.

  Here, since the heat seal portion always exists in the outer peripheral portion of the vacuum heat insulating material 3, if the vacuum heat insulating material 3 is interposed between the front surface material 2 and the back surface material 4, the outer peripheral portion of the front surface material 2 and the back surface material 4 A gap is generated between the outer peripheral portions. Accordingly, a void is formed in the outer peripheral portion of the interior building material 1 with a heat insulating material, and the hot-melt adhesive is filled in the void in the outer peripheral portion, so that the elastic spacing member 5a is formed in the outer peripheral portion.

  As a result, also in this embodiment, water vapor enters from the gap between the adjacent interior building materials 1 with heat insulating material by constructing the elastic interval holding members 5a of the adjacent interior building materials 1 with heat insulating material to elastically contact each other. Can be suppressed.

  Also in the present embodiment, since the surface material 2 and the back surface material 4 are joined by the elastic spacing member 5a having elasticity, the generation of internal stress due to the difference in elongation between the surface material 2 and the back surface material 4 is suppressed. be able to.

  By the way, in the embodiment in which the vacuum heat insulating material 3 is divided into a plurality of cells 3a as shown in FIG. 14B, heat is generated not only between the outer peripheral portion of the interior building material 1 with heat insulating material but also between the cells 3a. The seal part 3b exists.

  Therefore, in this embodiment, a space | gap is formed between the outer peripheral part of the interior building material 1 with a heat insulating material, and the cell 3a in an inside, and the space | interval between this outer peripheral part and the cell 3a is filled with a hot-melt-adhesive agent, and it is elastic space | interval. A holding member 5a is formed.

  As a result, in this embodiment, water vapor enters from the gap between the adjacent interior building materials 1 with heat insulating material by constructing the elastic interval holding members 5a of the adjacent interior building materials 1 with heat insulating material to elastically contact each other. It is possible to prevent water vapor from entering between adjacent cells 3a.
