Description

  The present invention relates to a method for building a heat shield building and a heat shield building.

  As a conventional heat insulating material for buildings, in a first example, there is a foam type heat insulating material such as glass wool or urethane board or an aluminum heat insulating material. The second example is an aluminum heat ray reflective material in which a resin-based bubble sheet and an aluminum foil are combined (Patent Document 1), which is used in a product developed and patented by the present applicant.

Japanese Patent No. 4226588

However, the first example has drawbacks in convection heat countermeasures, conduction heat countermeasures, radiant heat countermeasures, surface condensation countermeasures, and the like.
In the case of the second example, when the sheet was affixed to the outdoor side of the column and the crosspiece was nailed to the outdoor side with a nail, the following problem occurred due to the bubbles in the sheet. That is, when attaching, the sheet is attached from the lower side, and the lower edge of the upper sheet is attached to the outside of the upper edge. At this time, the overlapped portion becomes thick, which hinders the attachment of the crosspiece to the outdoor side with a nail. Further, if they are attached without being overlapped, the waterproof performance deteriorates due to the presence of a gap at the boundary.

The present invention solves the above-mentioned problems, and provides a method for constructing a heat-insulating building and a heat-insulating building that are excellent in measures against convection heat, measures against conduction heat, measures against radiant heat, measures against surface condensation, and excellent workability Objective.

  The present invention relates to a composite construction method in which a structural plate material is attached, and a heat insulating resin foam layer is formed by foaming and spraying a resin foamable liquid on site. An aluminum heat ray reflector is attached to the structural plate before or after foaming. Thereby, since the individual defects of the heat insulating material are compensated, high performance heat insulating performance can be expected. It is applied to places where heat insulation, heat insulation, heat insulation, and electromagnetic wave reduction are required, and contributes to improving the living environment, energy saving, anti-condensation measures, and thermal environment.

  That is, the method of the first problem solving means of the present invention includes a step of attaching a structural plate material to the outdoor side of a pillar / intermediate column, eaves girder and base, and a step of attaching an aluminum heat ray reflective material to the outdoor side of the structural plate material. , A step of attaching a ventilation trunk edge to the outdoor side of the aluminum heat ray reflective material with a gap, a step of attaching an outer wall finishing material to the outdoor side of the ventilation drum edge, and the inside of the spacing section on the indoor side of the structural plate And a step of foaming and spraying a hard urethane resin foamable liquid on site, a step of attaching an inner wall base to the indoor side of the stud, and a step of attaching an inner wall finishing material to the indoor side of the inner wall base. The aluminum heat ray reflective material is a combination of an aluminum foil and a resin bubble sheet, and has a thin edge piece that is thin and free of bubbles at one or both ends. It is located on the lower edge and is attached by stacking adjacent sheets.

The building of the second problem solving means of the present invention is a structural plate attached to the outdoor side of the pillars, studs, eaves girder and base, and an aluminum heat ray reflective material attached to the outdoor side of the structural plate, A ventilator rim attached to the outdoor side of the aluminum heat ray reflective material with a gap, an outer wall finishing material attached to the outdoor side of the ventilator rim, and the pillar / intermediate column on the indoor side of the structural plate A hard urethane resin foam layer foamed and sprayed in the space between the eaves girder and the foundation, an inner wall base attached to the indoor side of the pillar / intermediate pillar, and an indoor side of the inner wall base And inner wall finishing material. And the said aluminum heat ray reflective material is what combined aluminum foil and the resin bubble sheet | seat, and has a thin edge piece which became thin without a bubble in one end or both ends, and the said thin edge piece is made into an upper edge or a lower edge. It is positioned and attached adjacent sheets.

  The present invention combines three types of heat transfer: convection heat, conduction heat, and radiant heat by combining the aluminum heat ray reflective material and foaming hard urethane resin foaming liquid on site to form a heat insulating resin foam layer. On the other hand, the performance of heat insulation, heat insulation and heat insulation was demonstrated.

In addition, by blowing the resin foaming liquid on the aluminum heat ray reflective material on site, the workability is good and almost no dust is generated. In addition, the aluminum heat ray reflective material is handled as an outer heat insulating method, but since the thickness is small, problems in the support are less likely to occur. In addition, by blowing at the site, the gap is filled while foaming, and the airtight performance can be easily improved.
In addition, the aluminum heat ray reflective material is one in which an aluminum foil and a resin bubble sheet are combined, and one having one or both ends having a thin edge piece that is thin and free of bubbles. And when attaching, the said thin edge piece is located in an upper edge or a lower edge, and an adjacent sheet | seat is piled up and attached. At this time, the overlapped portion does not become thick and does not hinder the attachment of the crosspiece to the outdoor side with a nail.

  An embodiment of the present invention will be described below with reference to the drawings for an example of a conventional wooden construction method. The lower part of FIGS. 1 and 3 shows the wall structure 10. The structural plate 1p is attached to the outdoor side with a nail or the like over the pillar / intermediate column 11, eaves girder A5 (or torso A3), and base A2. Next, the aluminum heat ray reflective material 1 is attached to the outdoor side of the structural plate 1p with a tucker or the like. Here, a drainer 16 is attached to the structural plate 1 in the lower half of the base, and the reflector 1 is suspended from the outside. As the aluminum heat ray reflective material 1, the following is used, in which an aluminum foil is attached to both surfaces of a polyethylene resin-based bubble sheet.

  In FIGS. 1a, 1b, 1d, and 1e, an aluminum heat ray reflective material having a thin edge piece 1e that is thin and free of bubbles at one end, which is a combination of resin foam sheets interposed between two aluminum foils 1d and 1d. It is. In the bubble sheet, a large number of circular concavo-convex portions that are recessed from one surface of a right-angled quadrilateral planar sheet and project on the other surface have a concavo-convex sheet 1a that is uniformly distributed in a staggered manner. The first flat sheet 1b is attached to one surface and the second flat sheet 1c is attached to the other surface with the uneven sheet interposed therebetween, and has an extended portion beyond the side at the laterally opposite side of the uneven sheet. A bubble sheet is formed by the uneven sheet 1a and the first flat sheet 1b. In the aluminum foil 1d, the entire surface including the extended portion of the flat sheet of the bubble sheet is sandwiched and attached to one surface and the other surface.

  In FIG. 1a, the bubble distribution state in the bubble sheets 1a and 1b is as follows. On the vertical center line parallel to the vertical side of the right-angled quadrangular planar sheet 1b, the flat sheets 1b are arranged at equal vertical pitches P1. And on the adjacent vertical center line, it is shifted by 1/2 of the vertical pitch. Further, they are arranged at a lateral pitch P2 at equal intervals on the lateral center line parallel to the lateral side of the right-angled quadrilateral planar sheet. And on the adjacent horizontal center line, it is shifted by 1/2 of the horizontal pitch.

  In FIG. 1e, the uneven sheet 1a, the first flat sheet 1b, the second flat sheet 1c, and the aluminum foil 1d are pressure-bonded, and the extended portions are pressed from one side to the other side and adhered to each other with an adhesive. The thin edge piece 1e which became thin in the direction side is formed.

  Note that thin edge pieces may be formed at both ends as shown in FIG. In this case, the directions are point-symmetric with respect to each other. Moreover, in the said aluminum heat ray reflective material in FIG. 1d, you may abbreviate | omit either the 2nd plane sheet 1c and the aluminum foil 1d one side and the other side.

  In FIG. 1b, when attaching the said aluminum heat ray reflective material 1, a sheet | seat is attached from lower side, and an upper sheet | seat is piled up and attached to the outer side of the upper thin edge piece 1e. And the waterproof tape 3 of an aluminum foil is stuck on a boundary part. In FIG. 1c, the lower sheet is stacked on the inner side of the lower thin edge piece 1e of the upper sheet.

  Next, in FIG. 1, the ventilation trunk edge 12 which is long in the vertical direction is attached to the column on the outdoor side of the aluminum heat ray reflective material with a space left and right. The outer wall finishing material 13 is attached to the ventilator rim at the outdoor side of the ventilator rim.

  Then, on the indoor side of the structural plate material 1, a resin foaming liquid is foamed and sprayed in the field between the interval section of the stud 11, the eaves girder (or the trunk), and the base A 2.

That is, for example, the following raw materials and a spray foaming machine are used.
○ Raw material: Rigid urethane Product name: Foamlite HNB-6200J,
Composition (volume ratio) polyol component 100, isocyanate component 100,
Foaming agent: HFC-245fc, JIFC-365mfc
○ Spray machine: GUSMER FF-1600
○ Manufacturer: BASF INOAC
Polyurethane Co., Ltd. Address: 1-196 Kawamiya, Shinshiro City, Aichi Prefecture 1-196

  Next, an inner wall base 14 is attached to the indoor side of the pillar / intermediate column 11, eaves girder A5, torso A3 and base A2, and an inner wall finishing material 15 is attached to the indoor side of the inner wall base.

  As a result, the completed wall structure 10 is as follows. The structural plate 1p attached to the outdoor side of the pillar / intermediate column 11, the aluminum heat ray reflector 1 attached to the outdoor side of the structural plate, and the aluminum heat ray reflector attached to the outdoor side with a gap And the outer wall finishing material 13 attached to the outdoor side of the ventilator edge, and foamed in the space between the pillars / intermediate pillars 11 on the indoor side of the structural plate 1p. The sprayed resin foam layer 2 includes an inner wall base 14 attached to the indoor side of the stud, and an inner wall finishing material 15 attached to the indoor side of the inner wall base.

  In such a wall structure 10, an air layer 12 a that communicates with the outside air at the top and bottom by the ventilator edge 12 is formed within the interval between the outer wall finishing material 13 and the aluminum heat ray reflective material 1 (about 15 mm to about 40 mm). Therefore, due to the presence of this air layer (space), heat rays due to heat transmitted from the outdoor side are reflected (reflected by about 95%) by the aluminum heat ray reflective material 1. If this space does not exist, heat from the outside moves to the indoor side as heat conduction. Moreover, since the heat of the air layer escapes from the upper part by the upward airflow, the heat is not accumulated. In addition, moisture does not accumulate and the trunk edge does not rot.

  Here, only the aluminum heat ray reflective material has little effect on heat conduction and convection, and condensation occurs. The foamed resin layer alone does not reflect heat rays, so it absorbs heat and conducts. In the present invention, the respective disadvantages of the both are compensated for each other, and extremely excellent effects having the respective advantages are exhibited. In a static air layer, heat builds up due to solar heat (especially in summer), and the temperature rises, and moisture accumulates and the torso rots.

  Here, when using the aluminum heat ray reflective material 1 without a thin edge piece, it becomes as follows shown in FIG. 1g. At the time of attachment, the adjacent aluminum heat ray reflective materials 1 and 1 are attached to each other, and a waterproof tape 3 is applied to the boundary portion. This prevents water from entering the interior.

  As the resin foaming liquid, in addition to the above, a resin foaming raw material used in the field of building materials having excellent heat insulation and the like is applied. For example, a polymer foam material as a heat insulating material for filling and covering, in which a known two-component urea resin is injected and fired by a pump, open cell soft foamed polyurethane (such as maltoprene), polyethylene or chloride For example, a soft vinyl foam (closed cell). Also, a rigid urethane foam using carbon dioxide generated by mixing isocyanate and water as a blowing agent (manufacturer: Nippon Aqua Co., Ltd., address: 2-25 Kitamachi, Minami-ku, Nagoya City). It can also be applied to buildings such as steel structures and RC structures.

  The present invention is not limited to the embodiments and embodiments described above, and includes various modifications without departing from the scope of the claims.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a method for constructing a heat shield building, a heat shield building, an aluminum heat ray reflector, and various uses that require heat insulation, heat insulation, heat insulation, and electromagnetic wave reduction.
