Description

  The present invention relates to a snow melting heater for a roof.

  In snowy areas, snow can accumulate on the roof, causing damage to the building due to the load on the roof, and icicles forming on the eaves and rooftop parapets that can fall and cause personal injury and property damage. It has been viewed as a problem.

  Then, in order to prevent the melting of snow on the roof and the formation of icicles, it has been proposed that the heater is concealed and installed under the straw or parapet (Patent Documents 1 and 2).

  Further, a mat-shaped snow melting heater that can be easily installed on a metal plate such as a tin roof has been proposed (Patent Document 3). This is a sheet heater in which a heat generating electrode wire is disposed on a resin sheet material, a magnet sheet is disposed on the back surface thereof, and the sheet heater generates heat when energized.

  Also, a flexible magnetic sheet is provided on the back surface of the sheet-like heating element, while a flexible thin insulating waterproof material is provided on the surface of the sheet-like heating element in which electrode wires are arranged on a flexible sheet material. A snow melting heater material for roofs comprising a self-control heater wire along a longitudinal edge of the sheet-shaped heating element formed in a substantially rectangular shape is proposed. (Patent Document 4).

  However, in the heaters of Patent Documents 1 and 2, the heater is concealed and installed under the slats or parapets, so both the roofing work and the electrical work are required, and the construction period is long. In addition, there is a problem that the installation cost is inevitably high. In addition, the snow melting heater of Patent Document 3 does not generate enough heat particularly in the severe winter season, and it may be difficult to melt snow. Also, since the base material of the carbon sheet used for the heating element is a rubber system, it deteriorates over time. It had the difficulty of being easy to do. Further, the snow melting heater of Patent Document 4 is a type in which self-temperature control type heaters are installed at both ends, and there is a high inrush electric power. Therefore, a high-capacity electric equipment corresponding to this is required, and dozens of heaters are used. In the case of a large-scale facility such as that installed, there remains a problem in that it is necessary to install an electrical facility that is considerably more expensive than the originally required power facility.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a snow melting heater for a roof that can efficiently and low-cost melt snow on a roof and prevent formation of ice columns.

In order to achieve the above object, a snow melting heater for roof according to the first aspect of the present invention comprises:

The heat generating sheet is composed of a resin film coated with conductive particles, and an insulating layer covering the resin film,
At both end edges in the longitudinal direction of the heat generating sheet, a heat conductive sheet, a pair of electrode wires installed on the heat conductive sheet, and a heat generating wire disposed between the pair of electrode wires, A pair of high heat generating parts provided,
It is characterized by that.

It is a schematic cross section which shows the structure of the snow melting heater for roofs which is one Embodiment of this invention. It is a schematic cross section showing the structure of a heat generating sheet. It is a schematic plan view which shows the structure of a high heat-emitting part. It is a model perspective view which shows the state which installed the snow melting heater for roofs which is one Embodiment of this invention in the roof.

  First, the roof snow melting heater according to the present invention will be described in detail.

  A snow melting heater 100 for roof according to the present embodiment has a substantially rectangular sheet shape, and as shown in FIGS. 1 and 2, a magnet sheet 110, an inner exterior sheet 120, a heat generating sheet 130, and an outer side. An exterior sheet 140 and a protective sheet 150 are provided. As shown in FIG. 5, the roof snow melting heater 100 is installed on the eaves of the roof 10 to prevent snow melting on the roof 10 and the formation of icicles.

  The magnet sheet 110 plays a role of attaching and fixing the snow melting heater 100 for the roof to the eaves portion of the roof 10. In order to secure the flexibility of the snow melting heater 100 for the roof, a rectangular magnet sheet having a thickness of 0.6 mm is used as the magnet sheet 110. Even if the roof 10 has some unevenness, the roof snow melting heater 100 main body can be firmly attached.

  The inner exterior sheet 120 is bonded so as to overlap the magnet sheet 110. The inner exterior sheet 120 is made of ethylene propylene diene rubber (EPDM), and is a 1 mm thick sheet having substantially the same shape as the rectangular magnet sheet 110. The inner exterior sheet 120 plays a role of improving the waterproofness and weather resistance of the snow melting heater 100 for the roof.

  The heat generating sheet 130 is bonded so as to overlap the inner exterior sheet 120. A pair of electrode wires 136 a are arranged in the longitudinal direction of the heat generating sheet 130, and when the electrode wire 136 a is energized, the heat generating sheet 130 generates heat and prevents the roof 10 from melting snow and icing pillars. As shown in FIG. 3, the heat generating sheet 130 includes a resin film 130a (polyethylene terephthalate film) coated with a conductive particle material 130b (made of carbon and polyester), a resin film 130a, and a conductive particle material 130b ( And an insulating layer 130c (laminated film) that covers (made of carbon and polyester).

  A pair of high heat generating portions 132 are provided at both end edges in the longitudinal direction of the heat generating sheet 130 (FIGS. 1 and 2). As shown in FIG. 4, the high heat generating portion 132 includes a heat conductive sheet (aluminum sheet) 134, a pair of electrode wires 136b installed on the heat conductive sheet 134, and a pair of electrode wires 136b. The heating wire 138 is disposed. The heating wire 138 is made of carbon and generates heat when energized. For the purpose of insulation, a polyethylene terephthalate film (not shown) is bonded so as to cover the heating wire 138 and the heat conductive sheet 134. Since the heating wire 138 has a spiral-like shape, an electric resistance is generated when it is energized to generate heat, and heat is transmitted by the heat conductive sheet 134, so that the high heat generating portion 132 has a heating value of the heating sheet 130 main body. It is possible to generate heat with a heat generation amount about twice as large as the above. Since the heat generating sheet 130 generates heat and the high heat generating portion 132 generates heat more strongly, it is possible to efficiently and effectively prevent snow melting and ice columns.

  The outer exterior sheet 140 is bonded so as to overlap the heat generating sheet 130. The outer exterior sheet 140 is made of ethylene propylene diene rubber (EPDM), like the inner exterior sheet 120, and is a 1 mm thick sheet having substantially the same shape as the rectangular magnet sheet 110. The outer exterior sheet 140 serves to electrically insulate the electrode wires 136a and 136b disposed on the heat generating sheet 130 and to increase the waterproofness and weather resistance of the snow melting heater 100 for the roof.

  The protective sheet 150 is bonded so as to overlap the outer exterior sheet 140. The protective sheet 150 is made of ethylene propylene diene rubber (EPDM), and is a 1 mm thick sheet having substantially the same shape as the rectangular magnet sheet 110. A protective coating is further applied to the surface of the protective sheet 150. The protective sheet 150 plays a role of improving waterproofness and weather resistance of the snow melting heater 100 for roof.

  Note that the roof snow melting heater 100 is separately provided with lead wires (not shown) electrically connected to the electrode wires 136a and 136b for power feeding.

  As described above, the snow melting heater for roof 100 according to the present embodiment is provided with a pair of high heat generating portions 132 at both end edges in the longitudinal direction of the heat generating sheet 130. The heat generating part 132 generates heat more strongly. For this reason, it is possible to efficiently and effectively prevent snow melting and icicles even in the severe winter season.

  Further, since the heat generating sheet 130 of the snow melting heater 100 for roof according to the present embodiment uses a resin film 130a coated with conductive particle material 130b made of carbon and polyester, it is difficult to deteriorate over time. It can be used continuously for a long period of time, and the cost can be reduced.

  Moreover, since the snow melting heater 100 for roofs concerning this Embodiment can be affixed on the eaves part of the roof 10 with the magnet sheet 110, it can affix as long as a roof material is magnetic bodies, such as a metal. Can be used conveniently. Moreover, since it is not necessary to conceal and install it under a straw board or a parapet, installation cost can be suppressed.

  Further, since the snow melting heater 100 for roof according to the present embodiment is not a type in which a self-temperature control type heater is installed, it can be operated with normal electrical equipment, and installation costs can be reduced.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible. For example, in this embodiment, as shown in FIGS. 1 and 4, an aluminum sheet is used as the heat conductive sheet 134 provided in the high heat generating portion 132, and a carbon heating wire 138 is used. The heat conductive sheet 134 can be appropriately selected as long as it is a material capable of transmitting heat generated by the heating wire 138, and the heating wire 138 can be electrically connected by energization. Any material that generates heat by generating resistance may be used as appropriate.

  Further, in the present embodiment, as shown in FIGS. 1 and 4, the heating wire 138 provided in the high heat generating portion 132 has been described as having a spiral shape. Any shape can be used as long as the shape of the heating wire 138 can generate heat by generating resistance.

  In the present embodiment, the heating sheet 130 has been described with respect to a form in which carbon and polyester are used as the conductive particle material 130b, a polyethylene terephthalate film is used as the resin film 130a, and a laminate film is used as the insulating layer 130c. As for, any material that can be used as a conductive particle material, a resin film, and an insulating layer can be used as appropriate.

  Further, in the present embodiment, the inner exterior sheet 120, the outer exterior sheet 140, and the protective sheet 150 have been described with respect to forms using a 1 mm-thick ethylene propylene diene rubber (EPDM) sheet. Can be selected without any limitation as long as it can ensure the electrical insulation and the waterproofness and weather resistance of the snow melting heater 100 for roof, and the thickness can also ensure the flexibility of the snow melting heater 100 for roof. If so, it can be designed as appropriate.

  Moreover, in this embodiment, as shown in FIG. 5, although the form which adheres and installs in the eaves part of the roof 10 and performs the snow melting of the roof 10 and formation of an icicle was demonstrated, the roof of a building A snow melting heater 100 for roof may be installed on the parapet or headboard to prevent snow melting and icicle formation.
