Description

  This invention makes it a subject to provide a moisture-proof heat insulating material and a moisture-proof heat insulation structure using the same.

  For example, in a building for a steel framed housing, condensation may occur in the part due to heat bridge through the pillar part. For the purpose of preventing it, the part facing the inside of the pillar or the pillar on the indoor side, that is, It has been conventionally practiced to insert a fiber-based heat insulating material between vertical bars serving as the foundation of a wall material for interiors and to attach a moisture-proof sheet from the indoor side.

  However, attaching the moisture-proof sheet after installing the fiber-based heat insulating material between the vertical beam members requires two steps: installation of the fiber-based heat insulating material and application of the moisture-proof sheet. There is a problem that requires. In addition, when the heat insulating material is a fiber-based heat insulating material, it is necessary to proceed with the installation so that the installed heat insulating material does not fall down or fall down. It was a very difficult task.

  This invention makes it a subject to provide the moisture proof heat insulating material which can make construction of a heat insulating material and a moisture proof sheet | seat easy, and a moisture proof heat insulation structure using the same in view of the above problems.

  Said subject is solved by the moisture-proof heat insulating material (1st invention) characterized by making the foaming resin molding for heat insulation into the moisture-proof sheet in a bag state.

  In this moisture-proof heat insulating material, since the foamed resin molded body for heat insulation is put in a bag in the moisture-proof sheet, if the construction is performed using this, the heat-insulating material and the moisture-proof sheet can be installed at the same time. Can be done efficiently. And since a heat insulating material is a foamed resin molding, in a construction, a heat insulating material does not fall down or fall, and construction can be performed easily. In addition, since the heat insulating material is made of a foamed resin molded body, the moisture proof sheet is well supported by the foamed resin molded body from the inside, and the moisture proof sheet can be installed in an appropriate state simply by installing the moisture proof heat insulating material. it can.

  Further, in the moisture-proof heat insulating material described above, the foamed resin molded body is provided with a notch for dividing the foamed resin molded body into a plurality of parts, and the moisture-proof sheet is provided with the divided foamed resin molded body divided by the incision in a bag state. It is also possible to make them eccentric with each other (second invention).

  Further, according to the present invention, the foamed resin molded body in the moisture-proof sheet in the moisture-proof and heat-insulating material of the first or second invention is divided into a plurality of parts, and the divided foamed resin molded body is accompanied by a moisture-proof sheet in a bag state. And a moisture-proof and heat-insulating structure (third invention) characterized in that they are installed eccentrically with each other.

  In the second and third inventions, in the case where a plurality of heat insulating materials must be installed eccentrically with respect to the installation area, one moisture-proof heat insulating material is used, and the foamed resin molded body for heat insulation inside is used. If there is a notch, divide it using it, and if there is no notch, divide it by another method and install each of them so that they are eccentric from each other. Since it is in a state, the foamed resin molded body for split heat insulation is continuously moisture-proof with the moisture-proof sheet, and the moisture-proof treatment between the heat insulating materials installed in an eccentric state can be made extremely easy. . In particular, when a slit for splitting is provided in the heat-insulating foamed resin molded body in the moisture-proof sheet, it is easy to divide the heat-insulating foamed resin molded body even though the moisture-proof sheet is in a bag. It can be carried out.

  Further, in the present invention, the crosspieces serving as the base of the interior wall material are installed in parallel at a predetermined interval, and the moisture-proof heat insulating material of the first or second invention is installed between the crosspieces. In addition, a moisture-proof and heat-insulating structure (fourth invention) is provided in which the crosspieces are insulated in a moisture-proof state.

  In this structure, just installing the moisture-proof insulation between the crosspieces, the insulation and the moisture-proof sheet can be installed at the same time, and the insulation and moisture-proof construction can be carried out efficiently. Since the material is a foamed resin molded body, it can be easily constructed without falling down or falling down, and yet the heat insulating material is a foamed resin molded body, thereby preventing moisture between the crosspieces. The sheet can be in an appropriate moisture-proof state.

  In addition, the present invention includes a moisture-proof and heat-insulating structure in which the plurality of moisture-proof and heat-insulating materials of the first and second inventions are installed so as to be in a butted state with a moisture-proof sheet portion interposed therebetween.

  In this structure, if the moisture-proof heat insulating material is placed in a butted state, the moisture-proof sheet of the moisture-proof and heat-insulating material is interposed between the heat-insulated foamed resin molded products, and construction is performed between the foamed resin molded products for heat insulation. It can be easily made moisture-proof and continuous.

  Since the moisture-proof heat insulating material of the present invention and the moisture-proof heat-insulating structure using the same are as described above, the heat-insulating material and the moisture-proof sheet can be easily installed.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  The embodiment shown in FIGS. 1 to 4 is applied to heat insulation and moisture prevention of a pillar part of a building such as a house that employs a steel frame structure. In the cross-sectional structure of the building outer wall part shown in FIG. Are pillars, 2 and 2 are outer wall panels, 3 is a fiber-based heat insulating material, and 4 is a moisture-proof heat insulating material. Reference numeral 5 denotes an interior wall material made of gypsum board or the like.

  The column 1 is made of a square semi-hollow steel material with a lip that opens to the indoor side.

  The outer wall panel 2 includes an outer wall material 7 such as a ceramic industry on the outdoor side sandwiching the groove-shaped steel panel frame 6, and a tree serving as a base for mounting the interior wall material 5 on the indoor side sandwiching the panel frame 6 Further, a fiber-based heat insulating material 9 is provided on the back side of the outer wall surface material 7 so that the peripheral end portion protrudes into the groove of the panel frame 6, and the fiber system A moisture-proof sheet 10 made of an aluminum vapor-deposited sheet or the like is stretched on the indoor side of the heat insulating material 9, and the peripheral end portion of the moisture-proof sheet 10 is sandwiched between the panel frame 6 and the vertical rail 8 so that the moisture in the room is outside the wall. It does not enter the inside of the fiber-based heat insulating material 9 of the panel 2.

  As shown in FIG. 1, the moisture-proof heat insulating material 4 is a foamed resin molded body 11 such as polystyrene foam that is put in a moisture-proof sheet 12 in a bag. The internal foamed resin molded body 11 for heat insulation has a band plate shape, and a recess 13 for fitting the column 1 is provided on the surface portion that faces the column 1.

  In addition, the left and right side surface portions 14, 14 of the heat-insulating foamed resin molded body 11 are formed on slopes that inwardly incline toward the column 1, and heat insulating foam is formed on the left and right sides of the surface portion facing the indoor side. Slits 15, 15 extending in the longitudinal direction of the resin molded body 11 are provided.

  Further, a slit-like cut 16 is placed at a predetermined position in the longitudinal direction of the foamed resin molded body 11 for heat insulation, and the foamed resin molded body 11 for heat insulation is kept inside the bag while being in the bag. The moisture-proof sheet 12 that wraps the foamed resin molded body 11 can be divided into a plurality of foamed resin-molded bodies divided by the cuts 16 so that the moisture-proof sheet 12 is brought in the bag. So that they can be offset from each other.

  As shown in FIG. 3 (a), the outer wall panels 2 and 2 are constructed so that the panel frames 6 and 6 of the outer wall panels 2 and 2 are adjacent to both sides of the pillar 1 as shown in FIG. Installed. And as it is, since the pillar 1 part between the outer wall panels 2 becomes a heat bridge, the fiber-based heat insulating material 3 is packed in the inside of the pillar 1, and further, as shown in FIGS. A moisture-proof heat insulating material 4 is installed between the vertical rails 8 and 8 of the outer wall panels 2 and 2 sandwiching the pillar 1 from the indoor side.

  In this installation state, the moisture-proof heat insulating material 4 is in a state in which the pillar 1 is fitted into the recess 13 of the foamed resin molded body 11 for heat insulation through the moisture-proof sheet 12. Indoor moisture is prevented from entering the fiber-based heat insulating material 3 in 1.

  Further, both side surface portions 14, 14 of the heat-insulating foamed resin molded body 11 are pressed against the opposite surface portions of the vertical rails 8, 8 via the moisture-proof sheet 12 via the moisture-proof sheet 12, so that the moisture-proof sheet 12 is used for heat insulation. It is sandwiched between the foamed resin molded body 11 and the vertical bars 8 and 8, and a firm moisture-proof state is formed between the vertical bars 8 and 8. The left and right inclined side surface portions 14 and 14 of the foamed resin molded body 11 for heat insulation and the slits 15 and 15 extending in the longitudinal direction on the left and right sides of the indoor side surface portion are provided due to errors in material accuracy and on-site construction accuracy. This is useful for absorbing the error and also for facilitating the installation of the heat-insulating foamed resin molded body 11 between the longitudinal bars 8 and 8.

  In the above-described structure, the insulation between the vertical rails 8 and 8 is insulated and moisture-proof using the moisture-proof heat insulating material 4 in which the foamed resin molded body 11 for heat insulation is put into a moisture-proof sheet 12 in a bag state. If the moisture-proof heat insulating material 4 is installed, the heat insulating material 11 and the moisture-proof sheet 12 are installed at the same time, so that the heat insulation and moisture-proof construction can be performed efficiently. Moreover, since the heat insulating material 11 is made of a foamed resin molded body, the construction can be easily performed without falling down or falling down. In addition, since the heat insulating material 11 constituting the moisture-proof heat insulating material 4 is made of a foamed resin molded body, the moisture-proof sheet 12 is well supported by the foamed resin molded body 11 from the inside, and only the moisture-proof heat insulating material 4 is installed. The moisture-proof sheet 12 can be installed in an appropriate state.

  Further, the moisture prevention between the vertical bars 8 and 8 by the moisture-proof sheet 12 is achieved by installing the moisture-proof heat insulating material 4 in which the foamed resin molded body 11 is put in a bag in the moisture-proof sheet 12 between the vertical bars 8 and 8. Since it is completed at the position between the molded body 11 and the vertical rails 8 and 8, as shown in FIG. 3 (c), the horizontal rail 17 is moisture-proof even when the vertical rail 8 and the horizontal rail 17 intersect each other. The moisture-proof sheet 12 can be easily constructed without hindering the above.

  FIG. 4 (b) shows a case where the notched portion 1 a provided at the upper end of the pillar 1 is insulated and moisture-proof using the moisture-proof heat insulating material 4. The moisture-proof heat insulating material 4 is inside the moisture-proof sheet 12. Is divided into a plurality of parts using the above-mentioned cuts 16, one of the divided foamed resin molded bodies 11 a is along the general part of the pillar 1, and the other 11 b is fitted into the notch part 1 a at the upper end of the pillar 1, They are installed eccentrically so as to carry the moisture-proof sheet 12 in the bagged state. As described above, the foamed resin molded body 11 inside is divided in the moisture-proof sheet 12 in the bag state and installed in an eccentric state, so that the moisture-proof treatment between the divided heat insulating materials 11a and 11b is extremely easy. In the case of the embodiment, the construction of the air flow stop at the end of the column 1 can be facilitated.

  4 (B-1) and (B-2), for example, a plurality of moisture-proof heat insulating materials 4, 4 are interposed between the vertical rails 8 and 8 as described above, with the moisture-proof sheets 12 and 12 interposed therebetween. In the case where it is installed so as to be in an end butted state and insulated to a moisture-proof state, the moisture-proof heat insulating materials 4 and 4 are simply placed in the end-butted state so that the foamed resin molded bodies 11 and 11 are disposed. Can be made moisture-proof and continuous.
