Description

  The present invention relates to an installation structure of a vacuum heat insulating material used for heat insulation of a building or the like, and more particularly to an installation structure of a vacuum heat insulating material in which a vacuum heat insulating material is supported by an upper rail member and a lower rail member provided on a wall surface.

  A panel-like vacuum heat insulating material used as a heat insulating material for a building or the like is a material in which a core material (core material) is hermetically encapsulated with an outer sheet and the inside is decompressed to a vacuum (Patent Document 1).

  Patent Document 1 describes a method of applying a vacuum heat insulating material to a wall surface using a T-shaped body edge. FIG. 14 is a perspective view showing the vacuum heat insulating material construction method of Patent Document 1, and FIG. 15 is a horizontal sectional view thereof. As shown in the figure, an inner wall base plate 23 is attached to the outside of the pillar 22 of the building, and a vacuum heat insulating material 24 is attached to the outer surface side of the inner wall base plate 23 via a T-shaped body edge 21 having a T-shaped cross section. The T-shaped body edge 21 is fastened to one side of the vacuum heat insulating material 24 in advance and integrated with the vacuum heat insulating material 24. The T-shaped body edge 21 is fixed to the inner wall base plate 23 with nails 25, screws, bolts, needles, or the like. 14 and 15, the T-shaped body edge 21 is vertically distributed, and the left and right sides of the vacuum heat insulating material 24 are pressed by the T-shaped body edge 21. It is described that the T-shaped trunk edge 21 may be a horizontal trunk edge in the horizontal direction.

  In this Patent Document 1, the T-shaped body edge 21 is integrated with the vacuum heat insulating material 24 in advance, and the length of the T-shaped body edge 21 is the same as the length of one side of the vacuum heat insulating material 24. Therefore, every time a single vacuum heat insulating material 24 is attached to the inner wall base plate 23, it is necessary to fasten the T-shaped body edge 21 integrated with the vacuum heat insulating material 24 to the inner wall base plate 23 with a nail 25 or the like. The construction work takes a lot of time. Moreover, it is necessary to integrate the T-shaped body edge 21 with each vacuum heat insulating material 24, and the number of steps for integrating the T-shaped body edge 21 and the vacuum heat insulating material 24 is large, so that the work efficiency is poor. Furthermore, since the nail 25 or the like is punched on the T-shaped body edge 21 integrated with the vacuum heat insulating material 24, the vacuum heat insulating material 24 may be accidentally punched out by the nail 25 or the like. When the vacuum heat insulating material 24 is punched with a nail or the like, the vacuum of the vacuum heat insulating material 24 breaks and the heat insulating performance is impaired.

  Patent Document 2 discloses a wall panel mounting method in which an upper beam member and a lower beam member are attached to a wall surface in advance, and a wall panel that is not a vacuum heat insulating material is fitted into the upper beam member and the lower beam member in a fast manner. Is described. 16 (a) and 16 (b) are longitudinal sectional views showing the method of Patent Document 2.

  As shown in the figure, a deep groove portion 33 is provided in the upper crosspiece member 31, a shallow groove portion 34 facing the deep groove portion 33 is provided in the lower crosspiece member 32, and the upper end portion 36 of the wall panel 35 is inserted into the deep groove portion 33. The lower end portion 37 of the wall panel 35 is engaged with the shallow groove portion 34.

  The wall panel 35 is made of a wooden board material. The upper crosspiece member 31 is a parting edge member, and the lower crosspiece member 32 is a baseboard member. The upper crosspiece member 31 is fixed to the wall surface 30 by means of nailing or bonding, and the lower crosspiece member 32 is fixed to the wall surface 30 and the floor. It is fixed to the corner between the surface 40 by the same means. A plurality of wall panels 35 are held and constructed in a lateral direction between the upper crosspiece member 31 and the lower crosspiece member 32.

  The upper end portion 36 of the wall panel 35 is cut into a step shape so that a recess 39 is formed on the back side. A soft elastic body 38 having a substantially L-shaped cross section is bonded to the upper end portion 36.

  To construct the wall panel 35, the upper end portion 36 is inserted into the deep groove portion 33 of the upper crosspiece member 31 as shown in (a), and the lower end portion 37 of the wall panel 35 is set as the lower crosspiece member as shown in (b). The wall panel 35 is fitted between the upper crosspiece member 31 and the lower crosspiece member 32 steadily.

  Since the soft elastic body 38 is provided at the upper end portion 36 of the wall panel 35, the wall panel 35 is stable without being loose between the upper crosspiece member 31 and the lower crosspiece member 32 by the elastic restoring force of the soft elastic body 38. Fixed.

  In the structure of this patent document 2, since the hanging part 31a is provided in the front part of the upper crosspiece member 31, and the standing part 32a is provided in the front part of the lower crosspiece member 2, the wall panel 35 is steadily attached. It is necessary to press the wall panel 35 strongly upward and press the soft elastic body 38 strongly against the lower surface of the upper crosspiece member 31 to fully compress it when fitting into the expression, which takes time and labor. It will be a thing.

  Hereinafter, embodiments will be described with reference to the drawings.

  1 and 2 show an installation structure of a vacuum heat insulating material according to the embodiment, and a plurality of crosspiece members 2 are attached to a wall surface 1 horizontally and vertically in multiple stages. In this embodiment, the crosspiece member 2 has an upward L-shaped cross-sectional shape provided with an upright portion 2a that rises upward on the front end side. Reference numeral 2b indicates a recess on the rear side of the upright portion 2a. The entire lower surface of the crosspiece member 2 is a flat surface (horizontal surface in this embodiment). The crosspiece member 2 is a long member extending continuously across the upper and lower sides of the plurality of vacuum heat insulating materials 3.

  When constructing the vacuum heat insulating material 3, each crosspiece member 2 is previously attached to the wall surface 1 by a fixing means such as a nail, a screw, a tucker, or an adhesive. And it installs so that the vacuum heat insulating material 3 may follow a wall surface sequentially from a lower stage side preferably. At this time, it is preferable that the lower side portion of the vacuum heat insulating material 3 is inserted into the concave portion 2b of the lower beam member 2 (the beam member 2 positioned below the vacuum heat insulating material 3), and then the vacuum heat insulating material 3 is placed along the wall surface 1. .

  After the vacuum heat insulating material 3 is installed between the lower beam member 2 and the upper beam member (upper beam member) 2 as shown in FIG. 2A, the upper end surface of the vacuum heat insulating material 3 and the upper beam member 2 are disposed. The elastic filler 4 is pushed into the gap between the two. When the elastic filler 4 presses the vacuum heat insulating material 3 downward, the vacuum heat insulating material 3 is held between the crosspiece members 2 and 2 without being moved forward with respect to the wall surface 1.

  The elastic filler 4 is preferably made of a foamed synthetic resin such as foamed polyethylene or foamed polypropylene. The elastic filler 4 preferably has a cylindrical shape having a diameter of about 1 to 3 times the gap width between the upper end surface of the vacuum heat insulating material 3 and the upper crosspiece member 2. The elastic filler 4 is preferably a long object extending continuously along the upper end surface of the plurality of vacuum heat insulating materials 4.

  After the vacuum heat insulating material 3 is installed between all the crosspiece members 2 and 2, the face material 5 may be installed on the front side of the vacuum heat insulating material 3 as shown in FIG.

The face material 5 can be attached to the crosspiece member 2 by a fixing means such as a nail, a screw, a tucker, or an adhesive. When the face material 5 is attached, it is preferable that the gap interval d (FIG. 3) between the rear surface of the face material 5 and the front surface of the vacuum heat insulating material 3 is 20 mm or less. Thus, if the clearance gap d is made small, the convection of air will be suppressed and the heat insulation effect will become high.

The rear surface of the upper end portion of the vacuum heat insulating material 3 is in contact with the front surface of the hanging portion 2d. The elastic filler 4 is pushed between the upper end surface of the vacuum heat insulating material 3 and the lower surface of the crosspiece member 2D (the lower surface on the front side of the hanging portion 2d).

  In the vacuum heat insulating material installation structure of FIG. 5, there is a space between the wall surface 1 and the rear surface of the vacuum heat insulating material 3 by the thickness of the hanging portion 2d and the convex portion 2c. By setting the space S to 20 mm or less, air convection is suppressed and heat insulation is improved.

  In the above embodiment, the elastic filler 4 is pushed between the vacuum heat insulating material 3 and the crosspiece member, but the elastic filler may be provided on the lower surface of the crosspiece member in advance. FIGS. 6, 7 and 8 each show an example. 6 and 7, the elastic filler 6 having a square cross-sectional shape is attached to the lower surface of the crosspiece member 2 in advance by an adhesive, a pressure-sensitive adhesive, a double-sided tape, or the like. The front surface of the elastic filler 6 is flush with the front surface of the crosspiece member 2, and the rear surface is flush with the rear surface of the crosspiece member 2, but is not limited thereto.

The elastic filler 6 has a lower and upper thickness that the lower front edge side 6a sufficiently covers the front surface of the upper end portion of the vacuum heat insulating material 3 and prevents the vacuum heat insulating material 3 from being moved forward.

  In FIG. 8, the elastic filler 7 having a downward L-shaped cross-section is attached to the lower surface of the crosspiece member 2 in advance by an adhesive, a pressure-sensitive adhesive, a double-sided tape, or the like. The lower front portion of the elastic filler 7 is a convex portion 7a protruding downward, and the rear side of the convex portion 7a is a concave portion 7b. The front surface of the elastic filler 7 is flush with the front surface of the crosspiece member 2, and the rear surface is flush with the rear surface of the crosspiece member 2, but is not limited thereto.

  In order to install and install the vacuum heat insulating material 3 in FIG. 8, the upper end surface of the vacuum heat insulating material 3 is inserted into the recess 7 b of the elastic filler 7 of the upper cross member 2 and pressed upward, and then the vacuum heat insulating material 3 is attached to the wall surface. 1, then the vacuum heat insulating material 3 is slid downward, and the lower end of the vacuum heat insulating material 3 is inserted into the recess 2 b of the lower beam member 2. When the convex portion 7 a of the elastic filler 7 sufficiently covers the front surface of the upper end portion of the vacuum heat insulating material 3, the vacuum heat insulating material 3 is prevented from being moved forward.

  FIGS. 9A and 9B show an embodiment in which the crosspiece member is formed as a whole by an elastic member such as the above-mentioned foamed synthetic resin.

  A crosspiece member 8 is attached to the wall surface 1 by a fixing means such as a nail, a screw or an adhesive. In order to arrange the vacuum heat insulating material 3 between the upper crosspiece member 8 and the lower crosspiece member 8, the lower end portion of the vacuum heat insulating material 3 is pushed into the upper rear portion of the lower crosspiece member 8, and the vacuum heat insulating material 3 is placed along the wall surface 1.

  Next, the structure of a vacuum heat insulating material suitable for use in the present invention will be described with reference to FIGS.

  FIG. 10A is an exploded perspective view of the vacuum heat insulating material 15, and FIG. 10B is a non-disassembled perspective view of the vacuum heat insulating material 15. FIG.10 (c) is CC sectional view taken on the line of FIG.10 (b).

  The vacuum heat insulating material 15 is obtained by encapsulating a core material 12 with an outer skin 13.

  As the core material 12, various materials such as a fiber aggregate and a foamed resin can be used in addition to powder particles such as ceramic particles.

  In this embodiment, the outer skin 13 is formed by joining two sheet-like outer skin materials 14a and 14b as shown in FIG. Various materials such as a metal sheet such as aluminum, a resin sheet, and a metal laminate resin sheet can be used as the outer covering materials 14a and 14b. The outer peripheral members 14a and 14b are overlapped with each other at their peripheral portions, and the peripheral portions are fixed together in an airtight manner by a fixing method such as welding, fusion bonding, pressure bonding, or adhesion. Reference numerals 14c in FIGS. 10 (b) and 10 (c) indicate overlapping portions in which the peripheral portions of the skin materials 14a and 14b are overlapped (further fixed in this embodiment). By joining the skin materials 14a and 14b in this way, an airtight chamber is formed inside the skin 13 (between the non-peripheral regions of the skin materials 14a and 14b surrounded by the overlapping portion 14c).

  The overlapping portion 14c is disposed outside the hermetic chamber, and from the outer surface of the outer skin material 14a, 14b where the airtight chamber is formed (hereinafter simply referred to as the outer surface of the hermetic chamber). It extends like a bowl.

  The core material 12 is enclosed in an airtight chamber inside the outer skin 13. The hermetic chamber is depressurized to have a high degree of vacuum. Note that a getter agent that traps gas or moisture by adsorption or the like may be enclosed in the hermetic chamber. In the hermetic chamber, the core material 12 may be a single block having a size that occupies the whole of the hermetic chamber, or may be divided into a plurality of blocks.

  In this embodiment, the vacuum heat insulating material 15 has a square (rectangular or square) panel shape. The outer skin materials 14a and 14b may be referred to as front and back panel surfaces (hereinafter referred to as a front surface and a back surface of the vacuum heat insulating material 15), respectively, of the vacuum heat insulating material 15 on the front side (the side opposite to the mounted body) and the back side (mounted body side). .), And the overlapping portions 14c between the peripheral portions thereof are formed along the peripheral edges 15a, 15b, 15c, and 15d on the outer periphery of the rectangular vacuum heat insulating material 15.

  In this vacuum heat insulating material 15, as shown in FIG. 10C, the overlapping portion 14 c is formed so as to extend laterally flush with the front surface of the vacuum heat insulating material 15. That is, in this vacuum heat insulating material 15, the non-peripheral region of one outer skin material 14 a constitutes a region closer to the center than the overlapping portion 14 c in the front surface of the vacuum heat insulating material 15, and the non-peripheral region of the other outer skin material 14 b. Is the back surface of the vacuum heat insulating material 15 and the side surface of the vacuum heat insulating material 15 along the respective edge portions 15a, 15b, 15c, 15d on the back surface side of the vacuum heat insulating material 15 relative to the overlapping portions 14c (hereinafter simply referred to as vacuum heat insulating). It is referred to as the side surface of the material 15).

  It is preferable to fold the overlapping portion 14c along the side surface of the hermetic chamber as shown in FIGS. 11 and 12 in at least the upper side portion and the lower side portion of the vacuum heat insulating material 15 that engage with the crosspiece member. The overlapping portion may be folded on the entire side of the vacuum heat insulating material. In FIG. 11, the overlapping portion 14c overlaps only the side surface of the hermetic chamber. In FIG. 12, the superposition | polymerization part has gone around to the back side of an airtight chamber. Moreover, as shown in FIG. 17, the overlapping portion 14c may be folded back to the front side of the hermetic chamber. As shown in FIG. 18, the overlapping portion 14c is located near the middle of the vacuum heat insulating material 15 in the thickness direction, is folded along the side surface of the airtight chamber of the vacuum heat insulating material 15, and further wraps around to the back side of the airtight chamber.

However, like the outer skin 13A of the vacuum heat insulating material 15A in FIG. It may be composed of a skin material in a form other than the above.

  The outer skin 13A of FIG. 13 is composed of a cylindrical outer skin material 14d. When producing the vacuum heat insulating material 15A, the outer skin material 14d is spread flat in the panel surface direction of the vacuum heat insulating material 15A, and the core material 12 is inserted inside the outer skin material 14d. Next, the inner surface of the outer skin material 14d is decompressed, and the outer skin material 14d is opposed to the vacuum insulation material 15A in the panel thickness direction at one end side 14e and the other end side 14f in the cylindrical axis direction. The edges of the material 14d are overlapped. And these edge parts are airtightly fixed by the appropriate fixing means over the full width of the panel surface direction of the vacuum heat insulating material 15A and the cylinder axis direction of the outer skin material 14d. Thereby, the outer skin 13A which encapsulates the core material 12 from the cylindrical outer skin material 14d is configured.

  In the vacuum heat insulating material 15A provided with the outer skin 13A composed of the cylindrical outer skin material 14d, the four edge portions 15a to 15d of the vacuum heat insulating material 15A are orthogonal to the cylinder axis direction of the outer skin material 14d.

Further, as shown in FIG. 13C, the inner side of the outer skin material 14d is decompressed along the remaining pair of edge portions 15a and 15c facing each other in the direction orthogonal to the cylindrical axis direction of the outer skin material 14d. In this case, a superposed portion 14c ′ is formed in which the circumferential excess portion of the outer skin material 14d is folded. The overlapping portion 14c 'is preferably bent along the side surface of the hermetic chamber as shown in FIGS.

  It is to be noted that, by appropriately adjusting the circumferential length of the outer skin material 14d and the volume of the core material 12 so as not to generate an excessive portion in the circumferential direction of the outer skin material 14d, the peripheral portions 15a and 15c are overlapped with each other. It is also possible not to form 14c ′.

  In the present invention, after the vacuum heat insulating material is placed on the lower beam member, the elastic filler material is sprayed between the upper end surface of the vacuum heat insulating material and the lower surface of the upper beam member to spray the elastic filler. It may be formed.
