Description

  TECHNICAL FIELD The present invention relates to a curing material laid on a foam heat insulating material laid on a casing during a curing period, a curing method thereof, and a structure having a curing material.

  Conventionally, in the configuration of the outdoor part of a structure such as a rooftop or a balcony, for example, an ALC (Autoclaved Lightweight Aerated Concrete) or a floor base such as a plywood is laid with foam insulation for the purpose of obtaining a water gradient and heat insulation performance. A structure of external heat insulation such as laying a waterproof sheet thereon is well known.

  As the foam heat insulating material in this configuration, a thermoplastic synthetic resin foam is mainly used. However, after the construction, the temperature of the foam insulation rises due to the influence of sunlight and softens beyond the glass transition temperature, and the cells of the foam insulation expand under the pressure of the internal gas, so-called secondary foaming. A phenomenon may occur.

  As a method of suppressing the temperature rise of the floor basement and the basement under the floor with the foam heat insulating material laid under such a waterproof sheet, there is a method in which an aluminum foil is laminated directly on the waterproof sheet or a heat shield layer is formed on the surface layer. It is known (patent documents 1 to 3).

It is a typical vertical front view which shows the structure of the structure of embodiment of this invention. It is a typical vertical front view which shows the structure of the curing material of embodiment of this invention.

  An embodiment of the present invention will be described below with reference to the drawings. The curing material 150 of the present embodiment is a curing material 150 laid during the curing period on the foam heat insulating material 120 made of a thermoplastic resin laid on the housing 110, and as shown in FIG. 151 and a heat shielding layer 152 having a higher heat shielding property than the base material 151.

  As shown in FIG. 1, the structure 100 using such a curing material 150 includes a housing 110, a foam heat insulating material 120 made of a thermoplastic resin laid on the housing 110, and the foam heat insulating material 120. The waterproof sheet 140 to be laid, and the curing material 150 laid on the waterproof sheet 140 during the curing period and having a predetermined heat shielding property.

  More specifically, the casing 110 forms a so-called rooftop or balcony, and is formed of, for example, ALC or plywood that is lightweight cellular concrete. On the casing 110, a foam heat insulating material 120 having a predetermined plate thickness is laid. The foam heat insulating material 120 is made of a thermoplastic resin such as polystyrene foam or rigid urethane foam by an extrusion method or a bead method.

  An insulating sheet 130 and a walking board (not shown) are laid on the foam heat insulating material 120 as necessary. A typical example of the insulating sheet 130 is a polyethylene sheet, and a typical example of a walking board is a plate made of calcium silicate.

  A waterproof sheet 140 is laid on the insulating sheet 130. Examples of the waterproof sheet 140 include a sheet molded body made of vinyl chloride or polyolefin. A curing material 150 is laid on the waterproof sheet 140 at least during the curing period.

  Such a curing material 150 is temporarily fixed on the waterproof sheet 140 with an adhesive tape, for example. Such a curing material 150 is usually removed when the curing period ends, and a walking board or the like is installed on the upper surface. However, if the walking board or the like is not installed on the upper surface, it may be left as it is (not shown). ).

  The curing material 150 as described above includes, for example, as shown in FIG. 2, a resin base material 151 and a metal heat shield layer 152 formed on at least one surface of the base material 151. Such a resin base material 151 is formed in a sheet shape from, for example, polyethylene, PET (Polyethylene Terephthalate), polyester, random PP (polypropylene), or the like.

  The heat shield layer 152 is made of aluminum or the like. Such a heat shielding layer 152 is formed on the lower surface of the substrate 151 by vapor deposition or lamination. From the viewpoint of heat insulation, it is more effective to dispose the heat insulation layer 152 on the base material 151. However, in this case, since the reflectance is high and burdens the operator, the heat insulation layer 152 is provided on the lower surface of the base material 151. It is suitable to arrange in.

  Such a curing material 150 has a reflectance of 30% or more at least at wavelengths of 800 nm and 2100 nm. More specifically, the reflectance over the entire wavelength range of 800 to 2100 nm is 30% or more. Preferably it is 50% or more.

  Although such a curing material 150 can be formed exclusively, a conductive sheet laid on the lower surface of the waterproof sheet 140 can be used for damage inspection. Examples of such a conductive sheet include those obtained by laminating or coating a polyethylene sheet or a reinforcing cloth with a paint containing a conductive material such as a metal such as aluminum, a metal oxide, conductive carbon, conductive fiber, and metal powder. The curing material 150 as described above has a heat shielding property that prevents the foamed heat insulating material 120 from being secondarily foamed even when the direct sunlight and the sunlight reflected by the glass are irradiated all day.

  More specifically, the curing material 150 has a heat insulating property that the foamed heat insulating material 120 does not secondary foam even when the sunlight reflected by the glass and the direct sunlight are irradiated all day in the same position, and even if the glass is a pair glass, the foamed heat insulating material 120 has a thermal barrier property that does not cause secondary foaming. The heat shielding and heat insulating pair glass has a high reflectance of sunlight because the outer surface is coated with a metal film. The glass may be a pair of surfaces whose surfaces cross each other, or a vertically openable / closable type.

  In the structure 100 of this embodiment, in the structure 100 of the present embodiment, the curing material 150 having heat shielding properties is laid during the curing period on the foam heat insulating material 120 and the waterproof sheet 140 that are laid in order on the housing 110. The

  Curing is to protect and fix the foam heat insulating material 120, the waterproof sheet 140 and the like laid on the housing 110 from wind and rain for a predetermined period, and is realized by laying the curing material 150 as described above. .

  In the curing material 150 of the present embodiment, for example, even when direct sunlight and reflected sunlight from glass are irradiated all day, at least during the curing period, the foam heat insulating material 120 is made of the metal heat shielding layer 151. It can be insulated.

  Moreover, since the curing material 150 includes a resin base material 151 and a heat shield layer 152 formed on at least one surface of the base material 151, the structure is simple. As such a curing material 150, a conductive sheet laid on the lower surface of the waterproof sheet 140 can be used for damage inspection.

[Example]
Here, the results of actual experiments by the inventors will be described as examples. First, the curing material 150 prepared by the present inventor is obtained by laminating a heat shielding layer 152 made of aluminum foil on a polyethylene film surface on a base material 151 made of a laminate of a polyethylene film, a polyethylene nonwoven fabric, and a foamed polyethylene film. It consists of a formed structure. The polyethylene film constituting the substrate 151 has a thickness of 15 μm, the foamed polyethylene film has a thickness of 1 mm, and the heat shield layer 152 has a thickness of 7 μm. The thickness of the curing material 150 having this four-layer structure is 1.2 mm. Such a curing material 150 had a reflectance of 30% or more in a wavelength region of 800 to 2100 nm.

  The test environment is a position where reflected sunlight and direct sunlight by a pair of paired glasses whose surfaces intersect with each other are irradiated all over the same position, and the temperature at such a position is a high temperature of 90 ° C. or higher. In addition, the heat resistance of the foam heat insulating material 120 is about 70-100 degreeC. Such a temperature is measured by, for example, an existing spectrophotometer or infrared spectrometer.

  Then, when the curing material 150 as described above was laid as described above, the temperature of the foam heat insulating material 120 could be reduced by 10 ° C. or more. Then, it was possible to prevent thermal deformation and secondary foaming of the foam heat insulating material 120 of the structure during the curing period. In particular, since the curing material 150 has a reflectance in the wavelength range of 800 to 2100 nm of 30% or more, even if the direct sunlight and the reflected sunlight from the glass are irradiated all day, the thermal insulation 120 does not cause secondary foaming. Could occur.

  Furthermore, the curing material 150 can generate a heat shielding property in which the foam heat insulating material 120 does not undergo secondary foaming even when reflected sunlight and direct sunlight by a pair of glasses whose surfaces intersect with each other are irradiated at the same position throughout the day. Even with the paired glass, it was possible to generate a heat shielding property in which the foam heat insulating material 120 did not undergo secondary foaming.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, in the said form, the curing material 150 illustrated having the resin-made base material 151 and the thermal insulation layer 152 currently formed in the at least one surface of the base material 151.

  However, the curing material may consist of at least one of a glass cloth and a glass nonwoven fabric. Also in this case, since the curing material has a reflectance of 30% or more in the entire wavelength range of 800 to 2100 nm, even when the direct sunlight and the reflected sunlight from the glass are irradiated all day, the foam heat insulating material 120 is not shielded from secondary foaming. Thermal properties can be generated.

  Moreover, a curing material may consist of at least one resin sheet of white and silver. Such a curing material is formed by kneading at least one of white and silver pigments such as calcium carbonate, a hollow ceramic balloon, and titanium oxide in a resin sheet such as polyethylene.

  Also in this case, since the curing material has a reflectance of 30% or more in a wavelength range of 800 to 2100 nm, even if the direct sunlight and the reflected sunlight from the glass are irradiated all day, the heat insulating material 120 is not thermally foamed. Can be generated.

  Examples of the above-mentioned pigments include, for example, phthalocyanine-based, isoindolinone-based, perylene-based, azo-based, condensed azo-based, quinacridone-based, anthraquinone-based, aniline black-based, triphenylmethane-based pigments, except for carbon pigments. Dioxazine-based, titanium oxide-based, iron oxide-based, chromium oxide-based, lead chromate-based, spinel-type fired system, and the like can be used.

  Furthermore, in the said form, it illustrated that the reflectance in the wavelength range of 800-2100 nm of a curing material was 30% or more. However, since the curing material has a predetermined endothermic property and a predetermined heat capacity, the foamed heat insulating material 120 can generate heat shielding properties that do not cause secondary foaming even when irradiated with direct sunlight and sunlight reflected by glass all day. .

  Moreover, in the said form, the curing material 150 illustrated that the thermal-insulation layer 152, such as aluminum, was formed in the lower surface of the resin-made base materials 151 by vapor deposition or lamination. However, as described above, the heat shielding layer 152 may be positioned on the base material 151. Further, a curing material may be formed by bonding a so-called aluminum foil to the base material 151. In that case, the smooth surface and the rough surface of the aluminum foil may be used as the upper surface or the lower surface.

Needless to say, the above-described embodiment and a plurality of modifications can be combined within a range in which the contents do not conflict with each other. Further, in the above-described embodiments and modifications, the structure of each part has been specifically described, but the structure and the like can be changed in various ways within a range that satisfies the present invention.
