Description

  The present invention relates to a fixing structure of a heat insulating panel in which a vacuum heat insulating material is covered with a jacket material, and a building having the fixing structure.

  In recent years, global warming has become a major environmental problem, and there is a need to reduce energy consumption of electricity, gas, oil, and the like even in ordinary homes. However, in reality, the average temperature in summer increases year by year due to the influence of global warming, and the amount of energy used by air conditioners in ordinary houses tends to increase rather. Under such circumstances, a structure has been proposed in which a vacuum heat insulating material having high heat insulating performance is fixed to a wall, a floor, a ceiling, or the like in a general house, instead of a conventional heat insulating material using glass wool.

  A general vacuum heat insulating material is comprised from the core material and the gas-barrier film which seals and seals a core material inside (refer patent document 1, 2). A vacuum heat insulating material is fixed between the pillars of a building (refer patent document 3, 4).

  With reference to FIG. 28, the fixing structure of the vacuum heat insulating material disclosed in Patent Documents 3 and 4 will be described. In FIG. 28, columns 80 and 80, an outer wall member 90, and an inner wall member 92 are provided extending in the direction perpendicular to the paper surface. The vacuum heat insulating material 100 is disposed in a space surrounded by the columns 80 and 80, the outer wall material 90, and the inner wall material 92. The vacuum heat insulating material 100 includes a core material 14 and a gas barrier film 12 that hermetically seals the core material 14. For convenience of explanation, fin-like portions where the gas barrier films 12 are welded to each other at both ends of the gas barrier film 12 are defined as peripheral portions 102 and 102.

  In the natural state, the entire width of the vacuum heat insulating material 100 including the peripheral edge portion 102 (left and right direction in the drawing) is set longer than the dimension between the columns 80 and 80. By inserting the vacuum heat insulating material 100 between the columns 80, 80, a frictional force is generated between the peripheral portions 102, 102 formed in a fin shape of the vacuum heat insulating material 100 and the columns 80, 80. The vacuum heat insulating material 100 is fixed between the columns 80 and 80 by the frictional force.

  However, the fixing structure using only the frictional force can easily fix the vacuum heat insulating material 100 between the columns 80 and 80, but a gap is likely to be generated between the peripheral edge portion 102 and the column 80 due to deterioration over time. When the gap is generated, the heat insulating performance is lowered. Furthermore, the fixing structure using only the frictional force is likely to cause the displacement of the vacuum heat insulating material 100. Due to the displacement, not only the heat insulation performance is deteriorated, but also the gas barrier film 12 covering the core material 14 is damaged, and the vacuum inside the vacuum heat insulating material 100 may be broken.

  Referring to FIG. 29, there is also a structure in which the vacuum heat insulating material 100 is fixed between the columns 80 and 80 by using fastening means 70 such as a nail or a screw in order to prevent the occurrence of the above-described gap or misalignment. In the fixing structure, the fastening means 70 is provided so as to penetrate the peripheral edge portion 102 of the vacuum heat insulating material 100. The portion through which the fastening means 70 penetrates forms an opening at the peripheral edge 102 on the gas barrier film 12. The opening may expand to a portion covering the core material 14 due to aging or the like, and the vacuum inside the vacuum heat insulating material 100 may be broken.

  With reference to FIG. 30, the heat insulation panel currently disclosed by patent document 5 is demonstrated. In FIG. 30, for convenience of explanation, a part (part indicated by a one-dot chain line) is broken and illustrated. As shown in FIG. 30, the heat insulating panel 1 in Patent Document 5 employs a configuration in which the vacuum heat insulating material 100 is covered with a foam 104.

  Here, suppose that when the heat insulation panel 1 (FIG. 30) is fixed between the pillars of a building, the structure fixed using a frictional force as disclosed in Patent Documents 3 and 4 is adopted. According to the fixing structure, it is not possible to suppress the occurrence of a displacement that occurs between the heat insulating panel 1 and the pillar. A gap is generated due to the displacement, and the heat insulation performance is reduced.

  Further, suppose that a structure is adopted in which the heat insulation panel 1 (FIG. 30) is fixed using fastening means such as nails or screws as shown in FIG. According to the fixing structure, since the foam 104 covers the vacuum heat insulating material 100, the position of the vacuum heat insulating material 100 inside the heat insulating panel 1 cannot be visually recognized from the outside, and the fastening means is incorrect during installation. The vacuum inside the vacuum heat insulating material 100 may be broken by being driven into the above position.

It may be arranged (without touching the fixing member 310a).

  The materials of the core material 14, the gas barrier film 12, the jacket material 200, and the fixing members 310a and 310b are as follows, for example.

  For the core material 14 constituting the vacuum heat insulating material 100, pearlite, precipitated silica, aerosil (a kind of dry silica) or the like may be used as the inorganic powder (porous body). For the core material 14, urethane powder may be used as the organic powder (porous body). Glass fibers may be used for the core material 14 as inorganic fibers. For the core material 14, plastic fibers may be used as organic fibers. For the core material 14, open-cell urethane foam, ethylene foam, or styrene foam may be used as the organic foam. For the core material 14, other metals or organic honeycomb structures may be used.

  For the gas barrier film 12 constituting the vacuum heat insulating material 100, polyethylene, polypropylene, acrylonitrile or the like may be used as a heat-sealable resinous film.

On the gas barrier film 12, an aluminum foil, aluminum vapor-deposited PET (polyethylene terephthalate), silica vapor-deposited PET (polyethylene terephthalate), and an ethylene vinyl alcohol copolymer film are laminated with an adhesive or the like to further improve the barrier property. In addition, a laminate of the outside with a protective sheet such as PET (polyethylene terephthalate) or nylon may be used.

  For the jacket material 200, for example, a hard urethane foam can be used. Rigid urethane foams are amine-based catalysts or metal-based catalysts that can control the reaction to polyols, foam stabilizers, such as silicon that can control the cell shape in the foam, and foaming agents. As above, it is preferable to mix and mold the premix with water, cyclopentane, HFC141b, HFC245fa, HFC365, or the like and isocyanate. In addition to the rigid urethane foam, phenolic foam, polystyrene foam, polyethylene foam, or the like may be used for the jacket material 200.

  For the fixing members 310a and 310b, iron, SUS (stainless steel), AL (aluminum), or the like may be used as a metal material. For the fixing members 310a and 310b, ABS (a copolymer of acrylic, butadiene, and styrene), PP (polypropylene), PAN (polyacrylonitrile), vinyl chloride, or the like may be used as a resin material.

  With reference to FIG. 2, the heat insulating panel 1000 is fixed to the fixing target member by using the standing wall portion 32 of the fixing member 310 a (or the fixing member 310 b, hereinafter the same). Specifically, the heat insulation panel 1000 is disposed between the columns 80 and 80. Next, the fastening means 70 is penetrated from the inner side of the standing wall 32 toward the outer side (the column 80 side). The heat insulation panel 1000 is fixed between the columns 80 and 80 by the fastening means 70 and the columns 80 sandwiching (fastening) the standing wall portion 32 of the fixing member 310a.

(Action / Effect)
Since the heat insulating panel 1000 is fixed between the columns 80 and 80 using the fixing member 310a (the standing wall portion 32), it is possible to prevent the position of the heat insulating panel 1000 from being shifted between the columns 80 and 80 after installation. it can.

  A jacket material 200 is provided so as to cover the periphery of the vacuum heat insulating material 100. Although the position of the vacuum heat insulating material 100 inside the heat insulating panel 1000 cannot be visually recognized from the outside, the heat insulating panel 1000 can be fixed to the fixing target member using the standing wall portion 32 of the fixing member 310a. The position of the standing wall portion 32 and the position of the vacuum heat insulating material 100 are separated from each other, and the fastening means 70 is provided on the surface of the standing wall portion 32 in a direction orthogonal to the standing wall portion 32. At the time of installation, the fastening means 70 such as a nail or a screw is not struck toward the vacuum heat insulating material 100, and the vacuum inside the vacuum heat insulating material 100 can be prevented from being broken.

(Other configuration of the first embodiment: heat insulation panel 1001)
With reference to FIG. 3, another configuration of the first embodiment will be described. The heat insulating panel 1001 used for the other configuration is provided with soft foams 40 and 40 along the end surface 22 of the jacket material 200 and the end surface 24 of the jacket material 200, respectively.

  When the heat insulating panel 1001 is disposed so that the end surface 22 (or the end surface 24, the same applies hereinafter) of the jacket material 200 faces the column 80, a gap may be generated between the end surface 22 and the column 80. The flexible foam 40 can reduce the gap. The amount of air flowing through the gap is reduced, and high heat insulating performance can be obtained as compared with the fixing structure of the heat insulating panel 1000 in the first embodiment.

  You may employ | adopt the structure where the adhesive agent 42 is further apply | coated to the surface of the side facing the pillar 80 of the soft foam 40. FIG. When the width of the soft foam 40 is larger than the width of the gap (the left-right direction on the paper), the adhesive 42 bonds the soft foam 40 and the column 80. The gap is sealed, and higher heat insulating performance can be obtained. Pests can also be prevented from entering from the outside. As a material of the flexible foam 40, it is preferable to use a flexible urethane foam or a vinyl chloride foam.

  In the case where the soft foam 40 is not provided, a structure is adopted in which after the heat insulation panel 1001 is fixed to the fixing target member, the gap is sealed using a spray-type foaming urethane foam or a silicon sealing material. May be.

  Further, another plate-like outer covering material 210 may be further bonded to the surface of the base portion 30 of the fixing member 310a on which the standing wall portions 32 and 32 extend. Thermal insulation performance and rigidity as a fixing structure of the thermal insulation panel 1001 are improved.

(Still another configuration of the first embodiment)
Still another configuration of the first embodiment will be described with reference to FIGS. 4 and 5. Although the heat insulation panel 1000 used for the fixing structure of the heat insulation panel in Embodiment 1 described above includes two members, a fixing member 310a and a fixing member 310b (see FIG. 1), the invention is not limited thereto.

  With reference to FIG. 4, the heat insulating panel 1002 used in the further configuration includes one fixing member 314. A base portion 30 of the fixing member 314 is provided along the entire surface 26 of the jacket material 200. The standing wall portion 32 of the fixing member 314 is provided so as to extend from the end surface 21 side to the end surface 23 side of the jacket material 200. A plurality of openings 34 are provided on the standing wall 32. The heat insulation panel 1002 is fixed to a fixing target member (not shown) by passing a fastening means 70 such as a screw from the inside of the opening 34 toward the outside (the column 80 side).

  The base portion 30 and the standing wall portion 32 of the fixing member 314 are provided in a wider range than the heat insulating panel 1000. The base portion 30 and the standing wall portion 32 have higher bending rigidity than the heat insulating panel 1000. By adopting a structure in which the heat insulating panel 1002 is fixed between columns, the rigidity of the entire building can be greatly improved. When there is no need to improve the rigidity of the entire building, the number of pillars constituting the building can be reduced.

  As the number of pillars that make up the building decreases, the spacing between the remaining pillars increases. When the interval between the pillars is widened, it is possible to increase the size of the heat insulating panel 1002 fixed between the pillars, leading to a reduction in work man-hours.

  The standing wall portion 32 of the heat insulating panel 1002 can be provided with fastening means over a wider range than the heat insulating panel 1000. The heat insulation panel 1002 can be more firmly fixed between the columns.

  Referring to FIG. 5, standing wall portions 32, 32 may be further provided on the end surface 21 side and the end surface 23 side of the jacket material 200, as in the heat insulation panel 1003 used in the other configuration. By adopting a structure in which the heat insulating panel 1003 is fixed to a beam or the like constituting the ceiling or floor using the standing wall portions 32 and 32 provided on the end surface 21 side and the end surface 23 side of the jacket material 200, The heat insulation panel 1003 can be firmly fixed to a building or the like.

(Embodiment 2: fixing structure of heat insulation panel 2000)
A second embodiment based on the present invention will be described with reference to FIG. 6 and FIG. With reference to FIG. 6, the heat insulation panel 2000 used for the fixing structure of the heat insulation panel in this Embodiment is provided with the vacuum heat insulating material 100, the jacket material 200, and fixing member 320a, 320b.

  Since the structure of the vacuum heat insulating material 100 and the jacket material 200 is the same as that of the vacuum heat insulating material 100 and the jacket material 200 used in the first embodiment, the description thereof will not be repeated.

  The fixing member 320 a is bonded along the surface 26 of the jacket material 200. The fixing member 320 a has a predetermined width W <b> 2 in the direction connecting the end surface 21 of the jacket material 200 and the end surface 23 of the jacket material 200. The fixing member 320a fixes the heat insulation panel 2000 to a fixing target member (not shown).

  Referring to FIG. 7, fixing member 320a fixes heat insulation panel 2000 between columns 80 and 80 (members to be fixed), for example. The fixing member 320a is formed in a band shape, and has extended portions 36 and 36 that protrude from the surface 26 of the covering material 200 further outward (to the left and right in the drawing) while being bonded to the covering material 200. ing.

  Fastening means 70 is provided on the surface of the extending part 36 in a direction (vertical direction in the drawing) perpendicular to the extending part 36. The extending part 36 may have an opening on the surface thereof. The fixing member 320b is configured in substantially the same manner as the fixing member 320a.

  The heat insulating panel 2000 is fixed to the solid target member by using the extending portion 36 of the fixing member 320a (or the fixing member 320b, the same applies hereinafter). Specifically, the heat insulation panel 2000 is disposed between the columns 80 and 80. Next, the fastening means 70 is penetrated from the front surface side of the extending portion 36 toward the back surface side (column 80 side). The heat insulation panel 2000 is fixed between the pillars 80 and 80 by the fastening means 70 and the pillars 80 sandwiching (fastening) the extending portion 36 of the fixing member 320a.

(Action / Effect)
Since the heat insulating panel 2000 is fixed between the pillars 80 and 80 using the fixing member 320a (extension portion 36), the position of the heat insulating panel 2000 is prevented from being shifted between the pillars 80 and 80 after installation. Can do.

  The position of the extending part 36 and the position of the vacuum heat insulating material 100 are separated from each other, and a fastening means 70 is provided on the surface of the extending part 36 in a direction orthogonal to the extending part 36. At the time of installation, the fastening means 70 such as a nail or a screw is not struck toward the vacuum heat insulating material 100, and the vacuum inside the vacuum heat insulating material 100 can be prevented from being broken.

  In general, after the heat insulating panel 2000 is fixed, the outer wall material (90) (see FIG. 9) is fixed to the front surface side (upper side of the paper surface) of the columns 80 and 80. The outer wall material is fixed to the columns 80, 80 by fastening means (71, 71) such as minute nails.

  When the outer wall material is fixed to the columns 80, 80, the position of the vacuum heat insulating material 100 inside the heat insulating panel 2000 cannot be visually recognized from the side where the outer wall material is provided. If the fixing member 320a is not provided on the surface 26 of the jacket material 200 due to the fastening means (71) being driven in an incorrect position, the minute nail reaches the vacuum heat insulating material 100, and the vacuum heat insulating material is obtained. The vacuum inside the material 100 is broken.

  According to the fixing structure of the heat insulating panel 2000, the fixing member 320 a (and the fixing member 320 b) having the predetermined width W <b> 2 is bonded along the surface 26 of the jacket material 200, so that it is driven into an incorrect position. This prevents the minute fastening means 71 from reaching the vacuum heat insulating material 100. The vacuum inside the vacuum heat insulating material 100 can be prevented from being broken.

(Other configuration of the second embodiment)
With reference to FIG. 8, another configuration of the second embodiment will be described. The heat insulating panel 2001 used for the other configuration is similar to the heat insulating panel 1001 (other configurations of the first embodiment, the same applies hereinafter) along the end surface 22 of the jacket material 200 and the end surface 24 of the jacket material 200. Soft foams 40 and 40 are provided, respectively.

  The flexible foam 40 can reduce a gap generated between the end surface 22 (or the end surface 24, the same applies hereinafter) of the jacket material 200 and the column 80. The amount of air flowing through the gap is reduced, and high heat insulating performance can be obtained as compared with the fixing structure of the heat insulating panel 2000 in the second embodiment.

  Similarly to the heat insulating panel 1001, a structure in which the adhesive 42 is further applied to the surface of the soft foam 40 on the side facing the column 80 may be adopted. When the width of the soft foam 40 is larger than the width of the gap, the adhesive 42 bonds the soft foam 40 and the column 80. The gap is sealed, and higher heat insulating performance can be obtained. Pests can also be prevented from entering from the outside.

  As shown in FIG. 8, a protective plate 50 may be further provided on the surface 25 side of the jacket material 200.

  Referring to FIG. 9, generally, after the heat insulating panel 2001 is fixed between the columns 80, 80, the inner wall material 92 is fixed to the columns 80, 80 in addition to the outer wall material 90. The inner wall material 92 is fixed to the columns 80 and 80 by fastening means 71 and 71 such as minute nails.

  When the inner wall material 92 is fixed to the pillars 80, 80, the position of the vacuum heat insulating material 100 inside the heat insulating panel 2001 cannot be visually recognized from the side where the inner wall material 92 is provided. If the protective plate 50 is not provided on the surface 25 of the jacket material 200 due to the fastening means 71 being driven into an incorrect position, the fastening means 71 reaches the vacuum heat insulating material 100, and the vacuum heat insulating material 100. The vacuum inside will be destroyed.

  According to the fixing structure of the heat insulating panel 2001, the fastening plate 71 driven in an incorrect position reaches the vacuum heat insulating material 100 because the protective plate 50 is provided on the surface 25 of the jacket material 200. To prevent that. The vacuum inside the vacuum heat insulating material 100 can be prevented from being broken.

  Although the heat insulation panel 2000 used for the fixing structure of the heat insulation panel in Embodiment 2 is provided with two of the fixing member 320a and the fixing member 320b (refer FIG. 6), it is not restricted to this. Similar to the heat insulation panel 1002 in still another configuration of the first embodiment, the heat insulation panel 2001 in the present embodiment is applied to the entire surface 26 of the jacket material 200 from the viewpoint of improving rigidity and preventing vacuum breakage. You may provide the one fixing member provided along. Similarly, the protection plate 50 may be provided so as to cover the entire surface 25 of the jacket material 200.

(Comparison experiment result regarding other configuration of embodiment 2)
Regarding the other configuration of the second embodiment (fixing structure of the heat insulating panel 2001), the heat insulating panel 2001 is fixed between the columns 80 and 80, and the outer wall member 90 and the inner wall member 92 are fixed to the surfaces of the columns 80 and 80. A comparative experiment on heat insulation performance was conducted in the state (close to the actual use state).

  Referring to FIG. 10, a plate-shaped copper plate 89, inner wall material 92, pillars 80 and 80, and pillars 80 and 80 are fixed (in order from the bottom in the figure) in a heat insulating container 85 having an opening at the top. The heat insulation panel 2001, the outer wall material 90, and the silicon sheet 83 were accommodated so as to be sequentially stacked.

  The copper plate 89 is provided with a plurality of heaters 87 and 87 as heat sources. The silicon sheet 83 is provided with temperature sensors 84 near the pillars 80 and 80 and near the center of the heat insulating panel 2001, respectively. In addition to the temperature sensor 84, the silicon sheet 83 is provided with heat flow sensors 84S near the pillar 80 and near the center of the heat insulating panel 2001. As the heat flow sensor 84S, a heat flow sensor (size: 50 mm × 100 mm × 5 mm) of Shothrm HFM heat flow meter manufactured by Showa Denko KK was used. The thickness of the silicon sheet 83 was about 5 mm.

  A polyethylene bag containing water 86 and a large number of ice 88 was placed on the surface of the silicon sheet 83. In this state, the heater 87 was controlled so that the temperature of the copper plate 89 (corresponding to the warm end) was about 30 ° C. The heat flow Q per unit area at each position where the temperature sensor 84 is disposed was measured by the temperature sensor 84 (corresponding to the cold end).

Heat flow Q (W / m ² ), thermal conductivity λ (W / mK), thickness L of heat insulation panel 2001 (m: dimension between fixing member 320a and protective plate 50), ΔT (warm end temperature − There is a relationship of λ = Q × L ÷ ΔT with the cold end temperature (K)), and the average thermal conductivity of the composite material can be calculated.

As a result, the heat flow Q in the vicinity of the columns 80 and 80 was 5.4 (W / m ² ). The heat flow Q in the vicinity of the center of the heat insulating panel 2001 was 0.69 (W / m ² ).

On the other hand, the same experiment was performed by the aspect which remove | excluded the fixing member 320a, the protection board 50, and the soft foam 40 from the aspect of said experiment. As a result, the heat flow Q in the vicinity of the pillars 80 and 80 was 6.8 (W / m ² ). The heat flow Q near the center of the heat insulation panel was 0.8 (W / m ² ). It can be seen that the heat insulating performance is better when the fixing structure of the heat insulating panel 2001 including the fixing member 320a, the protection plate 50, and the soft foam 40 is employed.

  In the heat insulating panel 2001 including the fixing member 320a, the protection plate 50, and the soft foam 40, the thermal conductivity λ near the columns 80, 80 is expressed by the above formula (λ = Q × L ÷ ΔT: heat flow value Q , Thickness L, ΔT), it is 0.0023 (W / mK). This thermal conductivity λ is a value close to the combined thermal conductivity of the jacket material 200 and the vacuum heat insulating material 100.

  On the other hand, when the heat conductivity λ in the vicinity of the pillars 80 and 80 is calculated based on the above formula in the aspect excluding the fixing member 320a, the protective plate 50, and the soft foam 40, 0.0027 (W / mK) ). This also shows that the heat insulation panel 2001 provided with the fixing member 320a, the protection plate 50, and the soft foam 40 is superior in heat insulation performance.
