Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of dew condensation on outer side surface by continuously supplying a foamed rigid resin on a plywood board flowing continuously, restricting the thickness of foaming by a pushing pressure by an upper conveyor belt foaming on a board and laminating a surface member, the resin and the plywood. SOLUTION: For example, in an insulation method using a heat insulating material 6 at the outer side of a column 5, the material 6 is attached so as to have a joint 7 of the material 6 comes to a place of the column 5. Because of this, a defective position is created at the place of the column 5, and thus an insulation furring strip 1 is applied at the place of the joint 7 of the heat insulating material 6 and used so as to contact the surface member side to the material 6. At this time, insulation furring strip 1 is fixed from the plywood side to the column 5 with nails or machine screws. Then, a backing member 9 is attached from the top of the insulation furring strip 1, also, an exterior finish material or roofing material is paced on the backing member. By doing this, a space equivalent to the thickness of the insulation furring strip 1 is formed from the outer side of the heat insulating materiel 6 to the backing member 9, thereby preventing the occurrence of dew condensation on the surface of the material 6.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-insulating composite material, and more particularly to a heat-insulating rim used for improving heat-insulating confidentiality in a method of heat-insulating a building.

[0002]

2. Description of the Related Art A heat insulating material is widely used for an outer wall or a roof as a heat insulating method for a building. In particular, a rigid resin foam is a material that is indispensable for the heat insulation method because it has high heat insulation performance, is self-supporting, has excellent workability, and has excellent workability such as being available as a large plate. It has been pointed out that the following improvement is still required in the heat insulation method using such a hard resin foam. Although the hard resin foam is supplied as a large plate, it is difficult to cover the entire surface of the wall surface or the roof with a single piece of heat insulating material, so that a seam of the heat insulating material is formed on the construction surface.
If such a seam exists, even if cold air enters from the seam or the seam is sealed with an adhesive or the like to shut off the flow of air, the seam becomes a thermal bridge and reduces the heat insulation efficiency. In addition, the higher the insulation performance of the heat insulating material,
The temperature gradient on the outer surface of the heat insulating material is increased, so that a situation in which dew condensation easily occurs on the outer surface of the heat insulating material.

The present invention relates to a heat insulating shell obtained by bonding and integrating plywood.

[0005] By using the heat-insulating rim of the present invention and adopting the above-mentioned heat-insulating method, the heat-insulating efficiency can be remarkably improved, and a base material, an exterior material, or a roof is placed on the heat-insulating material via the rim.

BEST MODE FOR CARRYING OUT THE INVENTION The heat insulating fuselage of the present invention is a composite material having excellent heat insulating properties, obtained by laminating a face material / a hard resin foam / plywood. In the present heat insulating rim, a hard resin foam is used for imparting heat insulating properties to the rim. As the rigid resin foam, rigid polyurethane foam, polystyrene foam, polystyrene bead foam, high-density polyethylene foam, polypropylene foam, epoxy resin foam,
A phenol resin foam or the like can be used. Of these,
Preferred rigid resin foams are rigid polyurethane foams and polystyrene foams in terms of heat insulation performance, economy, self-adhesion, and the manufacturing process described later. Particularly preferred is a rigid polyurethane foam.

The plywood constituting the heat-insulating rim provides strength to the rim and enables nailing to the rim when attaching a base material for an outer wall or a roof.

The face material sandwiches the hard resin foam with the plywood to increase the strength of the entire rim, protects the surface of the hard resin foam which is a heat insulating material to prevent abrasion, and Water can be prevented from entering the heat insulating material. Further, in producing the body edge of the present invention by foaming the foamable resin, the face material has a useful function to cover the foaming resin from above to form a foamed surface. However, face materials are not always necessary. As a surface material having such a function, paper, plastic film, aluminum foil, or a laminate of any two or more of these can be used.

The heat insulating shell of the present invention can be manufactured by bonding each constituent material with an adhesive. However, from the viewpoint of productivity and economy, the self-adhesiveness of the hard resin foam during the manufacturing process is reduced. It is most rational to use and integrate. That is,
The foamable hard resin is continuously supplied on the plywood continuously flowing on the conveyor belt, the foamable hard resin is foamed on the plywood, and the face material continuously supplied from the foamed resin is formed. While coating, or without covering the face material, further press from above the upper conveyor belt,
This is a method of regulating the foam thickness of the foamable hard resin and bonding and integrating the face material / hard resin foam / plywood by the self-adhesive force of the resin.

[0010] The width when using the heat insulating rim of the present invention is:
There is no particular limitation as long as it is a dimension usually used as a waistline, and the width is generally 30 to 150 mm, preferably 40 to 150 mm.
70 mm. Also, it can be set arbitrarily according to the design specifications. The thickness of the rim (1), that is, the thickness of the composite material is 3 to 50 m for the hard resin foam (2) as a constituent material.
m, preferably 7-25 mm, plywood (3) 3-50 m
m, preferably 5 to 20 mm, and the total thickness of the composite material is 6 to 100 mm, preferably 10 to 60 mm,
More preferably, it is 20 to 40 mm.

Next, a heat insulating method using the heat insulating shell of the present invention will be described with reference to the drawings. FIG. 2 shows a heat insulating method using a heat insulating material (6) outside the pillar (5) or the stud (5). In the case of this construction method, in the present invention, the heat insulating material (6) is attached so that the seam (7) of the heat insulating material comes at the column or stud. Usually, an outer wall base material or an exterior material is mounted on the heat insulating material directly or through a vertical or horizontal rim. Therefore, a lack of heat insulation occurs at the pillar or stud. In the heat insulating method of the present invention, the heat insulating shell (1) of the present invention is used at the above-mentioned heat insulating material joint (7) such that the face material side is in contact with the heat insulating material. Insulated rim
The (1) is fixed to the pillar or stud from outside thereof, that is, from the plywood side, by a usual mounting material such as a nail (8) or a screw (8) in some cases. Next, a base material (9) is usually attached from above the heat insulation rim, and an exterior material (10) or a roof material is further attached thereon, thereby completing the heat insulation method of the present invention.
In some cases, for example, in the case of an exterior panel having both a base material and an exterior, the exterior material may be directly attached without attaching the base material. Further, an airtight tape (11) as disclosed in JP-A-2-178445 may be used between the seam of the heat insulating material and the heat insulating shell of the present invention. The hermetic tape may be attached at the time of construction, or may be integrated in advance as a part of the heat insulating fuselage with the face material side of the heat insulating fuselage.

By employing the heat insulation method of the present invention,
Defective portions of heat insulation due to the joint of the heat insulating material are eliminated, and the heat insulating efficiency of the heat insulating method can be significantly improved. Further, since a space corresponding to the thickness of the heat insulating shell can be formed outside the heat insulating material between the heat insulating material and the base material, it is possible to prevent moisture from condensing on the heat insulating material surface.

Hereinafter, the present invention will be described more specifically with reference to examples. Embodiment 1 FIG. 1 shows a heat insulating rim of the present invention. The rigid resin foam (2) is a closed-cell rigid polyurethane foam having an apparent density of 35 kg / m ³ and a thickness of 15 mm. Plywood (3) is 12m thick
m. The face material (4) is a kraft paper having a thickness of about 0.2 mm with an outer surface subjected to a water-repellent treatment. The overall thickness of the waist is about 27 mm and the width is 50 mm. No adhesive was used between the plywood and the polyurethane foam and between the polyurethane foam and the kraft paper, and the polyurethane foam was integrated by the self-adhesive property of the polyurethane in the production process.

Example 2 The heat insulation of the outer wall was carried out as shown in FIG. Width 455 mm, length such that seam (7) comes directly above studs or studs on studs (5) with center-to-center spacing of 455 mm and studs (5) mounted at 1800 mm. A 2700 mm polyurethane foam (6) was installed. Next, the above-mentioned heat-insulating rim (1) is applied to the seam (7) of the polyurethane foam (6), and nailing is performed from above to join the heat-insulating rim (1).
(7) Fixed to a pillar or stud below. Next
(1) A mortar base plate (9) was nailed to the rim using nails from above, and a mortar paint finish was applied from above the base plate to finish the heat insulating outer wall method.
