FIG. 1 is a perspective view showing a heat-insulation and moisture-proof unit 1 according to an embodiment, which includes a ventilation member 2 having a hollow portion 20 and a sheet-like heat-insulating reflector 3 and is disposed in a wall of a building. It is set as a unit member. The ventilation member 2 includes an indoor-side ventilation member 21 and an outdoor-side ventilation member 22, and the heat shield reflective material 3 is interposed between the ventilation members 21 and 22.

  A plurality of hollow portions 20 are arranged in parallel in the heat and moisture barrier unit 1. In the form shown in FIG. 2, the indoor-side ventilation member 21 and the outdoor-side ventilation member 22 have a common cross-sectional shape, and are formed symmetrically with the heat shield reflective material 3 interposed therebetween.

  Each of the indoor side ventilation member 21 and the outdoor side ventilation member 22 includes a flat plate portion 201 and a plurality of partitioning pieces 202 protruding from the flat plate portion 201 in the direction of the heat shield reflective material 3. In each of the ventilation members 21 and 22, a plurality of partition pieces 202 are extended in a direction orthogonal to the flat plate portion 201, and the edge portions of the partition pieces 202 are arranged to face each other with respect to the heat shield reflective material 3. Yes. The edge part of the partition piece 202 is joined to the heat shield reflective material 3, respectively. Thereby, the heat shielding reflective material 3, the partition piece 202, and the flat plate portion 201 divide both surfaces of the heat shielding reflective material 3 into a plurality of strips to form the hollow portion 20. In this case, the hollow portion 20 is provided in a substantially rectangular shape in cross section, and constitutes a hollow space extending along the longitudinal direction of the ventilation member 2.

  As shown in FIG. 1, the heat shield reflector 3, the indoor ventilation member 21, and the outdoor ventilation member 22 are integrated by bringing the edge of the partition piece 202 into close contact with the heat shield reflector 3. . The partition piece 202 and the heat shield reflective material 3 are joined by adhesion, welding, or the like.

  The indoor ventilation member 21 is preferably made of a sheet material or a plate material having moisture permeability. The outdoor side ventilation member 22 is preferably made of a sheet material or a plate-like material having moisture permeability or waterproofness, or having both moisture permeability and waterproofness. Moisture permeability refers to the property of mainly allowing water vapor (gas) to permeate, and waterproofness refers to not to allow water (liquid) to mainly transmit. For example, the indoor side ventilation member 21 and the outdoor side ventilation member 22 are both formed of a nonwoven fabric of synthetic resin fiber material. Preferred nonwoven fabrics include highly rigid polyethylene nonwoven fabrics and polypropylene nonwoven fabric spunbond nonwoven fabrics.

  The heat shield reflective material 3 is made of a sheet material having low radiation, and a thin metal sheet such as an aluminum foil or a stainless steel foil, or a metal vapor deposited sheet obtained by laminating a metal layer on a synthetic resin-based sheet material can be applied. Low emissivity refers to the property that emissivity for long-wavelength heat radiation can be kept extremely low.

  When the indoor side ventilation member 21 and the outdoor side ventilation member 22 are made of a common material, the nonwoven fabric molded body having a plurality of hollow portions having a rectangular cross section along the longitudinal direction is cut into two equal parts along the longitudinal direction. (See FIG. 2). Furthermore, the heat-insulation / moisture-proof unit 1 can be formed by sandwiching the heat-shielding reflector 3 between the halved ventilation members 21 and 22 and bonding them together.

  Although the indoor side ventilation member 21 desirably has moisture permeability, the outdoor side ventilation member 22 does not necessarily require moisture permeability. For this reason, the outdoor side ventilation member 22 may be comprised from the sheet | seat material or plate-shaped material of the material different from the indoor side ventilation member 21. FIG. For example, the outdoor-side ventilation member 22 is a waterproof sheet material or plate-like material, and may be formed of a moisture-permeable waterproof sheet or a synthetic resin-based plate-like material.

  As shown in FIG. 3, the heat and moisture barrier unit 1 may have a configuration in which the length in the width direction of the heat shield and reflector 3 is longer than the width of the ventilation member 2 and includes an ear portion 31. . In this case, the ear | edge part 31 of the heat insulation reflective material 3 can be used as a junction part with the pillar material etc. in a wall body. The ear portion 31 is not limited to the heat shield reflective material 3, and a sheet material or a plate material constituting the indoor side ventilation member 21 and the outdoor side ventilation member 22 is extended in the width direction of the ventilation member 2. It may be formed.

  Moreover, the heat-insulation and moisture-proof unit 1 may be configured to have different cross-sectional shapes for the indoor-side ventilation member 21 and the outdoor-side ventilation member 22. That is, as shown in FIG. 4, the plurality of hollow portions 20 may be arranged in an asymmetrical manner with the heat shield reflective material 3 interposed therebetween. Furthermore, the heat-insulation / moisture-proof unit 1 can be provided at an appropriate location on the side of the partition piece 202 without integrating the edge of the partition piece 202 with the heat-shielding reflector 3 when the strength is sufficiently secured. You may be set as the structure which provides a clearance gap between an edge part and the heat-shielding reflective material 3. FIG.

  In addition, the hollow part 20 with which the heat-insulation / moisture-proof unit 1 is provided is not limited to the rectangular shape as illustrated, but may have any cross-sectional shape such as a circular shape, an elliptical shape, or a triangular shape.

(Wall panel)
5-7 shows the wall panel 4 which concerns on embodiment of this invention. The heat-insulation and moisture-proof unit 1 can be used as a member constituting the wall panel 4 assembled to the outer wall of the building.

  As shown in FIGS. 5 and 6, the wall panel 4 includes an interior base material 41 disposed on the indoor side, the heat and moisture barrier unit 1 having the above-described configuration, and the interior base material 41 and the barrier. A heat insulating material 42 disposed between the heat and moisture-proof unit 1 is integrally provided.

  As for the heat insulating material 42, the outer surface facing the indoor side is covered with a moisture-proof film, and the outer surface facing the outdoor side and the end of the heat insulating material 42 are covered with a perforated film that is wind-proof and moisture-permeable.

  As shown in FIG. 6, a moisture-proof and air-tight sheet 43 is interposed between the wall panel 4 and the interior base material 41 on the indoor side of the heat insulating material 42 covered with the film. preferable. The moisture-proof and air-tight sheet 43 is made of, for example, a polyethylene film or an aluminum vapor-deposited film, and ensures moisture resistance and air-tightness inside and outside.

  These members constituting the wall panel 4 are integrated in advance by bonding and adhesion and are carried into the construction site of the building. By being panelized in advance, the construction accuracy can be improved, and the construction process can be reduced and the construction period can be shortened. In general, the moisture-proof and air-tight sheet 43 is easily broken and easily damaged. However, since it is built in the wall panel 4 in advance, it is possible to prevent damage at the construction site and to exhibit sufficient moisture-proof and air-tight performance. become.

  As shown in FIG. 7, the wall panel 4 includes a structural surface material 44 disposed on the outdoor side, a heat insulating material 42 disposed on the indoor side, and the structural surface material 44 and the heat insulating material 42. The heat and moisture insulation unit 1 disposed between the two may be integrally provided. In this case, the structural proof strength as the wall panel 4 can be improved by comprising the structural face material 44.

(Building exterior wall structure)
8-11 is sectional drawing which shows the outer wall structure of the building comprised using the above-mentioned thermal-insulation moisture-proof unit 1 or the wall panel 4. As shown in FIG. These heat-insulation and moisture-proof unit 1 and wall panel 4 can be applied to the outer wall structure of a relatively small-scale building such as a wooden house.

  As shown in FIGS. 8 and 9, in the outer wall structure according to the embodiment, a plurality of pillar members 5 are erected at a predetermined interval, and an interior base material 41 such as a gypsum board is provided on the indoor side of the pillar member 5. Is provided. Here, the column material 5 includes not only columns constituting the frame of the building such as pipe columns and through columns, but also inter-columns arranged between the columns, vertical bars, and other vertical members in general. .

  On the outdoor side of the interior base material 41, a moisture-proof and airtight sheet 43 is stretched and a heat insulating material 42 is provided. The moisture-proof and air-tight sheet 43 prevents indoor water vapor from flowing into the heat insulating material 42. As for the heat insulating material 42, the outer surface facing the indoor side is covered with a moisture-proof film, and the outer surface facing the outdoor side and the end of the heat insulating material 42 are covered with a perforated film that is wind-proof and moisture-permeable.

  On the outdoor side of the heat insulating material 42, the heat-insulation and moisture-proof unit 1 is disposed. As shown in FIG. 8, the heat and moisture insulation unit 1 is loaded together with the heat insulating material 42 between the column members 5 such that the plurality of hollow portions 20 are arranged along the height direction, and the depth of the column member 5 is increased. The whole is contained in the dimensions. The outer surface of the outdoor ventilation member 22 of the heat and moisture barrier unit 1 is aligned with the outdoor surface of the column member 5. In this case, the above-described wall panel 4 according to the embodiment of FIG. 6 can be applied to such an outer wall structure by mounting it between the column members 5 from the indoor side of the column members 5.

  An outer wall material is provided on the outdoor side of the heat and moisture barrier unit 1. As an outer wall material, in the illustrated embodiment, a structural surface material 44 is stood on the outdoor side of the pillar material 5, and an exterior finishing material 6 is disposed via a base material 61 such as a paddle. A moisture permeable waterproof sheet 45 is stretched on the outdoor surface of the structural face member 44 without any gaps. Since the heat insulating material 42 and the heat-insulating and moisture-proof unit 1 are housed between the pillar materials 5, the structural face material 44 can be brought into close contact with the pillar material 5 and joined.

  The structural face material 44 can be formed as a load bearing wall by being stretched by a single plate between the pillar material 5 and the pillar material 5.

  A ventilation layer 7 is provided between the exterior finishing material 6 and the structural face material 44. The above-described wall panel 4 according to the embodiment shown in FIG. 7 can be realized by placing the wall panel 4 between the column members 5 from the outdoor side and attaching the wall panel 4. In this case, the wall panel 4 according to the form of FIG. 7 is applied to a range from the base of the building to the trunk difference or a range from the trunk difference to the girder, and forms an outer wall structure having a bearing wall with high structural strength. Can do.

  FIG. 9 shows the outer wall structure of FIG. 8 in a longitudinal section. Between the column members 5, a heat insulating material 42 and a heat and moisture barrier unit 1 are housed. As shown in the figure, water vapor generated on the indoor side is prevented from flowing into the wall body by the moisture-proof and airtight sheet 43. In addition, since the heat insulating material 42 has a configuration in which the indoor side is covered with a moisture-proof film, the inflow of moisture into the heat insulating material 42 is prevented, and heat loss can be greatly reduced to enhance the heat insulating effect. it can.

  Even if moisture flows into the heat insulating material 42 from the indoor side for some reason, the moisture is discharged to the outdoor side of the heat insulating material 42 by the perforated film covering the outdoor side of the heat insulating material 42. For this reason, the moisture that has flowed in even in a small amount is discharged from the heat insulating material 42, flows into the indoor ventilation member 21 of the ventilation member 2, and stays in the heat insulating material 42. Since the indoor side ventilation member 21 is provided with a plurality of hollow portions 20 along the height direction, moisture circulates through the hollow portion 20 from below to above. The lowermost ends of the hollow portion 20 and the vent layer 7 are connected to vents provided on the building foundation, and the uppermost ends thereof are connected to vents provided on the roof. It rises and is discharged.

  On the other hand, wind and rain from the outside is blocked by the exterior finishing material 6 and the moisture-permeable waterproof sheet 45 provided on the outdoor side. Heat conducted and radiated through the exterior finishing material 6 due to solar radiation or the like, and moisture that has flowed in a small amount into the indoor side flow through the ventilation layer 7 between the structural face material 44 and are discharged upward. Moreover, the ventilation layer 7 also raises the moisture generated under the floor and discharges it.

  There is a possibility that solar heat, which is particularly high in the summer, is conducted from the ventilation layer 7 to the structural face material 44 and radiated. In that case, heat is exhausted upward from the hollow portion 20 of the outdoor-side ventilation member 22. Since the heat shield reflector 3 is disposed between the outdoor vent member 22 and the indoor vent member 21, heat is transferred to the outdoor vent member 22 and further to the outdoor side by the heat shield reflector 3. It is reflected and conduction / radiation to the indoor side of the heat-shielding reflector 3 is prevented.

  10 and 11 are cross-sectional views showing other outer wall structures according to the embodiment. In the form shown in FIG. 10, the outdoor side ventilation member 22 of the heat and moisture barrier unit 1 is disposed on the outdoor side of the column member 5. Thereby, compared with the form of FIG. 8, the thickness of the heat insulating material 42 can be ensured, the heat insulating performance can be enhanced, and the wall body can be formed with a reduced thickness. As shown in FIG. 3, the heat-insulation and moisture-proof unit 1 adopts a structure in which the heat-insulating / reflecting material 3 is provided with the ears 31, so that the ears 31 can be joined to the column members 5. it can.

  In the form shown in FIG. 11, the entire heat and moisture barrier unit 1 is disposed on the outdoor side of the column member 5. A base material 61 is attached to the outdoor side of the pillar material 5, and the heat-insulation and moisture-proof unit 1 is placed between the base materials 61. Thereby, compared with the form of FIG. 8, the thickness of the heat insulating material 42 can be increased or the ventilation layer 7 can be provided on the indoor side, and combined with the action of the hollow portion 20, the moisture discharge performance can be improved. it can.

  The outer wall structure of FIGS. 10 and 11 is a form that does not include the structural face material 44, and therefore can be suitably implemented in a place where it is not required to be a load bearing wall. Moreover, since the heat-insulating reflector 3 of the heat-insulation / moisture-proof unit 1 is disposed on the outdoor side of the column 5, there is no need to stretch a separate moisture-permeable waterproof sheet on the outdoor side of the column 5. A simple structure can be realized.

  The outer wall structure configured as described above and the wall panel 4 applicable thereto are configured such that the heat-shielding reflector 3 in the heat-and-moisture-proof unit 1 includes hollow portions 20 on both the outdoor side and the indoor side. The air circulation property in the ventilation member 2 is ensured. Therefore, in the heat and moisture prevention unit 1, it is possible to sufficiently exhibit the heat shielding / reflecting performance of the heat shielding / reflecting material 3, and the outdoor side ventilation member 22 is imparted with heat radiation to the outdoor side, thereby providing indoor side ventilation. The member 21 is provided with moisture ventilation and exhaustability. Therefore, in the room inside the building, the influence of the outdoor environment is minimized and a comfortable indoor environment is maintained. Further, in the wall, heat loss and condensation of the heat insulating material 42 can be prevented, and corrosion deterioration in the wall can be prevented for a long time.

  In addition, the heat-insulation moisture-proof unit 1, the wall panel 4, and the outer wall structure of a building which concern on this invention can be implemented with other various forms besides the said embodiment. For example, the hollow portions 20 in the heat and moisture insulation unit 1 are not limited to being arranged in a row in the indoor side ventilation member 21 and the outdoor side ventilation member 22, but may be arranged in a plurality of rows. Further, as the outer wall structure, a plurality of heat-insulation / moisture-proof units 1 may be stacked and placed between the pillar members 5. The above-described embodiments are examples of the present invention, and the present invention is not limited to these.

  The present invention can be suitably used for relatively small wooden buildings such as houses.
