Japanese Patent No. 6598337

The most important thing to pay attention to in outdoor heat insulation work is that the heat insulation material is blown off by the wind. To prevent this, the surface of the roofing material should be cleaned, and the heat shield should be completely adhered to the roofing material to prevent wind from entering. To do this, apply an adhesive to the entire surface of the roofing material and attach a heat shield.
However, solvent-based materials are mainly used as adhesives, and the surface temperature of the roofing material is limited to about 40 ° C., and when the temperature is higher than that, it dries in a short time and is liable to cause poor adhesion. Therefore, when an adhesive composed of a solvent-based material is used, there is a problem that it cannot be constructed in the summer.

In order to deal with this problem, a method is known in which a heat-resistant double-sided tape such as butyl tape or acrylic tape is used and a heat shield is attached to the roof material. This construction method is a construction method in which the heat shield material is adhered by attaching double-sided tape only to the bottom of the recess of the roofing material.

In this construction method, when the heat shield material is attached to a wide folded plate roof, double-sided tape is first applied to the recessed portion of the folded plate roof material. Subsequently, the total length of the concave portion and the convex portion of the cross section of the folded plate roof is measured to determine the width of the heat shield material, and the roll-shaped heat shield material is cut. After that, spread the roll-shaped heat shield material and lay it down into the folded plate roofing material, press the corners of the bottom of the recess with a resin spatula, etc., and make an inverted trapezoidal shape while making creases in the longitudinal direction. .. That is, a heat shield having the same shape as the folded plate roof can be formed in the longitudinal direction.

Next, the heat shield material is lifted upward and pulled toward the front side so that the end portion of the double-sided tape can be seen, the release paper of the double-sided tape is peeled off, and the heat shield material is attached.
However, in this process, the more the heat shield material is pulled toward you, the farther the end of the double-sided tape is from the operator, and there is a problem that it cannot be constructed by one person. In addition, there are many times when the wind is blowing outdoors, and the sheet-shaped heat shield is susceptible to wind resistance, and even if the corners are bent, it cannot be applied accurately and the finish is not clean. is there.
Furthermore, when an adhesive is used, the heat shield and the folded plate roofing material are in close contact with each other, so there is no space and there is no corrosion due to electrolytic corrosion, but when only double-sided tape is used, this corrosion occurs. There is also a problem.

[First Embodiment]
A mode for carrying out the present invention will be described with reference to FIGS. 1 and 2.
There are two ways to install the heat shield on the outdoor side of the roof: with adhesive or with double-sided tape. Most of the adhesives are solvent-based, and when the adhesive surface becomes hot, they often dry and cause poor adhesion, and cannot be used unless the surface temperature of the roofing material is about 40 ° C or lower. Since the temperature of the folded-plate roofing material in summer rises to 80 ° C., it is not realistic to apply a heat shield material with an adhesive in summer. This alternative is double-sided tape, and by using double-sided tape, construction can be performed even when the temperature of the adhesive surface is around 80 ° C, and on-site construction can be performed throughout the year.

Conventionally, a method of fixing the heat shield material by attaching double-sided tape to the bottom of the recess of the roof material of the roof having unevenness has also been used, but in this method, the heat shield material once positioned is lifted in the air. Therefore, it is difficult to deal with the wind that is constantly blowing, and there is a problem that the position is deviated from the set position and the finish is not beautiful. Further, the construction method in which the heat shield material is lifted is difficult to work by one person, so that a plurality of installers are required and the construction cost is high.

The heat shield structure 10 for an uneven roof according to the present embodiment is formed on an uneven roof such as a folded plate roof or a tiled roof. The heat shield structure 10 of the uneven roof includes a convex portion 12 on the sunlight side and a side surface (side portion) 13 from the convex portion 12 to the concave portion 11 of the folded plate semi-roofing material (roof material) 7 constituting the roof. A double-sided tape 9 is provided on the roof, and the outdoor heat-shielding material (heat-shielding material) 1 is positioned on the entire surface of the folded plate semi-roofing material 7 from the sunlight side via the double-sided tape 9.

In the present embodiment, first, since the target is a folded plate roof with a large area of the recess 11 such as a goby fold or a tiled roof, the builder stands in the recess 11 when performing heat shielding work. Basically, you can work as it is. Secondly, it is basically possible to construct by one person. Thirdly, in order to finish it neatly, the outdoor heat shield 1 once positioned is adhered without moving as much as possible.

From this point of view, double-sided tape such as butyl tape and acrylic tape is attached to the side surface 13 of the concave portion 11 and the side surface 13 of the convex portion 12 of the uneven roofing material 7 such as a folded plate roof or a tiled roof. The double-sided tape 9 is not provided on the bottom of the recess 11.
If the double-sided tape 9 is on the bottom surface of the outdoor heat shield material 1, the heat shield material 1 must be pulled upward in order to peel off the release paper of the double-sided tape 9, but it should be installed on the side surface 13 of the recess 11. For example, the release paper of the double-sided tape 9 can be easily peeled off by simply folding the outdoor heat shield 1 inside the recess 11 of the roofing material 7 without moving the bottom surface, and if it is returned again, the outdoor shield can be peeled off. The heat material 1 can be brought into close contact with the roof material 7. Further, since the double-sided tape 9 such as butyl tape can be installed (used) even when the temperature of the roofing material 7 is high (for example, 80 ° C.), heat shielding work can be performed even in the summer, and the heat shield work can be performed throughout the year. Construction is possible at any time.

The outdoor heat shield material 1 includes a diffusely reflective layer 2 of a highly transparent resin containing a coloring pigment and the like and which transmits radiant heat well, a material 3 having a high reflectance to radiant heat such as aluminum foil, an adhesive film 4, a non-woven fabric, a glass fiber and the like. 5. Adhesive film 4, material 3 having high reflectance to radiant heat such as aluminum foil, and 7 layers of highly permeable resin layer 6 that transmit radiant heat well are laminated in order from the sunlight side.

Since the outdoor heat shield material 1 is usually adhered to the entire surface, it has a high reflectance to radiant heat such as a diffused reflective layer 2 and aluminum foil coated with a highly permeable resin containing a coloring pigment or the like that well transmits radiant heat from the sun side. Material 3, adhesive film 4, non-woven fabric, glass fiber, etc. 5, adhesive film 4, aluminum foil, and other materials 3 having high reflectance to radiant heat are sequentially laminated. However, when the double-sided tape 9 is used, a very small space 8 is formed between the outdoor heat shield material 1 and the roof material 7, and when moisture invades this space 8, it causes electrolytic corrosion. Therefore, the surface of the outdoor heat shield material 1 that comes into contact with the roof material 7 is subjected to electrolytic corrosion treatment. By performing the electrolytic corrosion treatment, it is possible to prevent electrolytic corrosion due to humidity.

In the present embodiment, a space 8 is formed between the roof material 7 and the outdoor heat shield material 1 by providing the highly permeable resin layer 6 that transmits radiant heat well on the indoor side of the outdoor heat shield material 1. Even in this case, the structure is such that electrolytic corrosion can be prevented.
In consideration of the possibility that the air expands and the outdoor heat shield 1 expands in the summer, the gap formed between the outdoor heat shield 1 and the roofing material 7 as in the space 8 is formed. It is also possible to prevent the formation by applying an adhesive in advance.

Material 3 with high reflectance to radiant heat such as aluminum foil has a high reflectance to radiant heat of 95% to 98%, and if it is used outdoors as it is, sunlight will be reflected and damage the human eye or cause aviation damage. It can also be a factor that causes it. Therefore, the diffused reflection layer 2 contains a coloring pigment or the like in a highly transmissive resin that transmits radiant heat well, and diffusely reflects sunlight to avoid damaging the human eyes or causing aviation obstacles. There is.
Further, by applying the diffuse reflection layer 2 of a highly transparent resin containing the coloring pigment or the like to the surface of the material 3 having a high reflectance to the radiant heat such as aluminum foil, the radiant heat such as aluminum foil can be dealt with. The acid resistance and alkali resistance, which are the weak points of the material 3 with high reflectance, are improved, and it can be used outdoors for a long period of time without corrosion.

The material 3 having a high reflectance to radiant heat such as aluminum foil generally has a purity of 99.5% or more and a thickness of about 5 to 10 μm.

The adhesive film 4 used for the outdoor heat shield material 1 is a material for heat welding a material 3 having a high reflectance to radiant heat such as aluminum foil and a non-woven fabric or glass fiber 5. For example, a polyester film can be used. ..

In the heat shield structure 10 of the uneven roof according to the present embodiment, the double-sided tape 9 is not provided on the bottom of the concave portion 11, and the double-sided tape 9 is provided on the convex portion 12 of the roofing material constituting the roof and the side surface 13 of the concave portion 11. Since the outdoor heat shield 1 is attached to the entire surface of the material 7, when the outdoor heat shield 1 is attached to the roof material 7 of a folded plate roof or a tiled roof, the outdoor heat shield 1 stands alone at the bottom of the recess 11. It can be constructed, and even if the wind blows, it can be constructed neatly without shifting from the groove, and it can be easily constructed.
Therefore, by constructing the heat shield structure 10 of the uneven roof on the roof having unevenness, the work efficiency can be improved and the construction cost can be reduced.

Further, by constructing the heat shield structure 10 of the uneven roof according to the present embodiment on the roof, it is effective for significant energy saving measures and heat stroke measures.
