B) is a plan view showing the state of attachment to the shaft assembly. 1 and 2, reference numeral 1 is a heat insulating material made of a foamed resin molding material, and 2 is a moisture-proof sheet made of a synthetic resin that is attached to the interior side surface by thermocompression bonding or adhesion.

  The heat insulating material 1 is formed as a foamed material by heating a synthetic resin as a raw material in a mold. In the present embodiment, the heat insulating material 1 is constituted by a plurality of heat insulating material bodies 1a to 1c.

  FIG. 3A is a rear view of the heat insulating material 1 viewed from the indoor side, and FIGS. 3B and 3C are views showing a coupling structure between the heat insulating material bodies 1a and 1b. The material body 1b has a portion that is approximately half the thickness of the heat insulating material body 1b, and the extending portion 3 has a plurality of extending portions 3a to 3c whose ends are enlarged. The other heat insulating element body 1a is formed with a concave portion 4 into which the extending portion 3 fits in a half thickness of the heat insulating material element body 1a, and the concave portion 4 has a shape in which the plurality of extending portions 3a to 3c are respectively fitted. Receiving portions 4a to 4c. The heat insulating element bodies 1a and 1b are joined by fitting the extending portion 3 to the concave portion 4 as shown in FIGS. 1 (A), 1 (B), and 3 (A).

  With this coupling structure, relative rotation as shown by an arrow R in FIG. 3A and slipping out as shown by an arrow S can be prevented, and the moisture-proof sheet 1 can be attached to the heat insulating material element. The bodies 1a to 1c are prevented from shifting in the vertical direction of the cross section.

  The heat insulating material 1 is a first-floor frame consisting of columns (or studs), studs, foundations, torso, lintels and window sills, or columns (or studs), studs, torso, twill beams, lintels and windows. It is fitted into the opening of the second floor frame or ceiling rafter, eaves and purlin, or the opening between the timbers constituting the floor, as shown in FIG. Side surfaces 8 on both sides of 1 are formed in a taper shape, and grooves 5 for facilitating the reduction of the width are formed on the left and right sides of the indoor side surface over the entire length. Moreover, although the groove | channel 6 provided vertically in the center part of the heat insulating material 1 is also provided in order to attain further reduction in width | variety, this groove | channel 6 of this center part is not necessarily required. Further, a plurality of grooves 7 are provided in the horizontal direction to facilitate the reduction of the width in the vertical direction.

  The left and right widths of the heat insulating material 1 correspond to most of the dimensions that can actually exist at the interval of the shaft set, so that the outdoor side width a shown in FIG. Is set to 39 to 47 cm. Further, the thickness t of the heat insulating material 1 is set to 2 cm to 12 cm, and it is possible to attach a brace to the outdoor side as a general pillar having a width (10 to 12 cm) or less in the indoor / outdoor direction. If not, the thickness can be designed freely. In this embodiment, the depth h of the grooves 5 to 7 is 2 cm to 10 cm, and the width w of the grooves 5 to 7 is 5 mm to 15 mm.

  Grooves 9 for providing cutout holes for accommodating the switch box are provided on the left and right sides of the middle portion of the heat insulating material 1 on the substantially indoor side in the height direction, and cutout holes for receiving the outlet box are provided on the left and right of the lower part. A groove 10 is provided to provide

  As shown in FIGS. 1 (A) and 1 (B), the moisture-proof sheet 2 is provided around the heat insulating material 1 with portions protruding from the heat insulating material 1 from the side and upper and lower surfaces, and the protruding portions are attached to the mounting edges 2a and 2b. To do. In the present embodiment, the widths c and d of the mounting edges 2a and 2b on the side surface and upper and lower surfaces are 12 cm and 12 cm, respectively.

  As shown in FIG. 2B and FIG. 4, this heat insulating panel is attached by being fitted from the indoor side into a shaft set composed of, for example, a pillar 11, a spacer 12, a base 13, and a trunk difference 14. In this case, the height of the heat insulating material 1 is cut off at the upper and lower ends in accordance with the height in the shaft assembly. When the heat insulating material 1 is pushed in, both side surfaces 8 of the heat insulating material 1 are deformed by being pressed against the pillars 11 and the inter-columns 12, and the width of the groove 5 is narrowed to facilitate pushing. Further, the groove 6 provided in the center in the vertical direction is also slightly narrowed to facilitate the pushing of the heat insulating material 1. Also in the vertical direction, the grooves 7 provided in the horizontal direction facilitate the reduction of the vertical width of the heat insulating material 1.

  When the heat insulating material 1 is pushed into the shaft assembly in this way and the indoor side surface of the heat insulating material 1 coincides with the indoor surface of the wood constituting the shaft assembly, the attachment edges 2a and 2b of the moisture-proof sheet 2 are stapled 15 to each other. It fixes or adheres to the pillar 11, the intermediate pillar 12, the trunk difference 15, or the flooring 16 with a fixing tool such as. After the moisture-proof sheet 2 is attached, excess portions of the attachment edges 2a and 2b are cut off.

  As shown in FIG. 5, in the case of a heat insulating panel to be constructed in a place where the switch box 17 needs to be provided, the heat insulating material 1 and the moisture-proof sheet are formed along the rectangular groove 9 for providing the notch hole 18. 2 corresponding parts 16 are cut out, and after attaching the switch box 17 to the part corresponding to the notch hole 18, a heat insulating panel is constructed. Reference numeral 19 denotes a closing member made of a foamed resin heat insulating material provided to close the outside of the portion cut out to accommodate the switch box 16 and is cut and attached to a predetermined size at the construction site. . Reference numeral 20 denotes a finishing material to be constructed on the indoor side of the moisture-proof sheet 2.

  Similarly, for a heat insulating panel to be installed in a place where an outlet box needs to be provided, a place for accommodating the outlet box (not shown) by cutting the heat insulating material 1 along the rectangular groove 10 and the corresponding place. A portion of the moisture-proof sheet 2 is cut out.

  Thus, since the heat insulation panel of this invention attaches the moisture-proof sheet | seat 2 to the room inner side of the foamed resin heat insulating material 1, attachment of the heat insulation panel from the room inner side is attained. For this reason, even after the bracing is applied to the shaft assembly, it is possible to install the heat insulating panel as long as the bracing can be attached to the outdoor portion of the shaft assembly or closer to the outdoor side. Further, in the present invention, the heat insulating material 1 made of foamed resin is used. However, the foam material is essentially difficult to condense, and moisture penetrates into the inside as in the case where the fiber is used for the heat insulating material. The material is not deteriorated and the heat insulating property is not lowered. Moreover, since the moisture-proof sheet | seat 2 was provided in the indoor side of the heat insulating material 1, it is prevented that the moisture on the indoor side flows out to the heat insulating material 1 side, and dew condensation is prevented, and the dew condensation in the heat insulating material 1 is better prevented.

  Further, the side surface 8 of the heat insulating material 1 has a tapered shape in which the width on the indoor side is larger than the width on the outdoor side, and has grooves 5 that facilitate the reduction of the width on at least both sides of the indoor side. When the width of the opening is narrow, the width of the groove 5 is reduced to facilitate the insertion of the heat insulation panel into the shaft set, and the difference in the interval between the openings in the shaft set due to the size of the pillars 11 and the intermediate pillars 12 etc. Can be easily handled.

  Moreover, since the groove 9 for providing the notch hole for accommodating the switch box 16 and the groove 10 for providing the notch hole for accommodating the outlet box are provided on the indoor side of the heat insulating material 1, the switch box and the outlet box are provided. It becomes easy to form a notch for accommodating the.

  Further, as shown in FIG. 6, the groove 5 can be set to a width that allows the electric wiring 21 to pass therethrough and the electric wiring 21 can be passed therethrough. With this structure, the electrical wiring 21 is protected by the heat insulating panel, and the indoor wiring 21 can be set in an orderly manner, and does not interfere with the subsequent interior finishing.

  In the said embodiment, the heat insulating material 1 of 1 sheet is comprised by the several heat insulating element | base_body 1a-1c. Such a configuration is advantageous in that it can be molded by a general molding machine without requiring a large and dedicated molding machine. This is because the molding machine for this type of heat insulating material 1 is based on the molding of the packing material, and any heat insulating material up to 134 cm × 158 cm can be molded by a general-purpose molding machine. However, since the molding material used for the walls of this type of building requires a length of about 300 cm, a general molding machine cannot be diverted to mold this as a single molding material. Necessary and a large capital investment is required. However, the heat insulating material shown in the above embodiment has a length of 158 cm such that the width is 39 cm and the length of the heat insulating element bodies 1a to 1c is 95 cm (or 1a, 1b = 95 cm, 1c = 65 cm), respectively. Since the one heat insulating material 1 is comprised by the combination of the heat insulating element bodies of the following length, capital investment is reduced significantly. As is clear from the above description, even if the heat insulating material 1 is constituted by a plurality of heat insulating element bodies, it can be formed using a general molding machine.

  Thus, when making the heat insulating material 1 into a division structure, the structure which joins the short surfaces of a simple-shaped board | plate material with an adhesive agent is also employable. However, with such a structure, there is a gap without a heat insulating material at the joint, so that the ends of the heat insulating material bodies 1a and 1b as in the above embodiment and FIGS. 7A and 7B. It is preferable to halve the width of the portions 3A and 3B so that the portions 3A and 3B overlap each other as shown in FIG. 7C. In any case, the moisture-proof sheet 2 serves as an adhesive that prevents the heat insulating element bodies 1a and 1b from separating from each other.

  FIG. 8 shows a more preferable structure of the heat insulating material combination structure. In this structure, as shown in FIG. 8A, a recess 22 having a half width is formed at the end of the heat insulating element body 1a, and a protrusion 23 and a hole (or recess) 24 are formed in the recess 22. Form. The other heat insulating element body 1b is formed with an extension portion 25 that fits into the recess 22 at the end thereof, that is, half the thickness of the element body 1b. 23 and a hole (or a recess) 24 and a projection 26 are formed, respectively, and are combined as shown in FIG. 8C.

  With such a combined structure, first, the protrusions 23 and 26 and the holes (or recesses) 27 and 24 against the pulling force that the heat insulating element bodies 1a and 1b tend to come off in the length direction, In addition, the frictional force caused by the fitting between the extension portion 23 and the recess 22 does not come out of resistance. Moreover, the frictional force between the protrusions 23 and 26 and the holes (or recesses) 24 and 27, and the extension 25 and the recesses against the pulling force that the heat insulating element bodies 1a and 1b tend to come off in the thickness direction. 22 does not come off due to the frictional force due to the fitting with 22.

  Furthermore, since the moisture-proof sheet 2 is affixed to the heat-insulating element bodies 1a and 1b, the moisture-proof sheet 2 has a shearing force on the entire bonding surface against the force that the heat-insulating element bodies 1a and 1b tend to come off in the longitudinal direction. Because it resists with, it cannot be removed. In addition, the adhesive force of the moisture-proof sheet 2 does not resist and resist the pulling force that the heat insulating element bodies 1a and 1b tend to come off in the thickness direction. Further, by chamfering the tips of the protrusions 23 and 26 and the entrance portions of the holes (or recesses) 24 and 27, it becomes easy to enter even if there is a slight misalignment between the positions, and the heat insulating element bodies 1a and 1b. The combination work between the two can be facilitated and the work efficiency can be improved.
