Abstract

PROBLEM TO BE SOLVED: To provide a mat-shaped snowmelt heater material which can be installed on a concrete surface or a mortar surface. SOLUTION: A flexible sheet material 11 is provided with a flexible thin insulating waterproof material 17 on the surface of a sheet heater 10 in which an electrode wire 12 is arranged, while the back surface of the sheet heater is flexible. It is configured to include the adhesive sheet material 14. Since the adhesive sheet material is provided on the back surface of the flexible sheet heater, if the roof surface material (roofing plate) is a magnetic material (structure containing iron), the adhesive sheet material on the back surface becomes the roofing material by magnetic force. Adsorb. If energized in that state, the ice and snow will be melted by the action of the heating element, so no specialized construction of the roof surface material is required. In addition, no electrical work is required to install the snowmelt heater material. [Selection diagram] Fig. 1

Description

  The present invention relates to a heater material that melts snow on a wall surface of a building or a rooftop.

  In snowy areas, there is a problem that the building is damaged by the snow accumulated on the roof, or the ice and snow generated at the eaves and the top edge of the building (so-called parapet) falls, resulting in personal injury and property damage.

  For this reason, conventionally, a structure has been proposed in which an electric heater is provided under a roofing board of a roof or under a parapet to melt snow. For example, JP2003-020760A, JP2001-349019A, and the like.

  The problem of snow on the roof is often solved in the case of sloping roofs of houses such as gables and ridges, especially if the ice and snow lump that occurs at the eaves can be eliminated. Japanese Patent Laid-Open No. 2001-349019 (Patent Document 2) is a proposal from that viewpoint. If the snow on the roof of the building is melted at the edge (parapet), accidents can be prevented, so many buildings in snowy areas are not visible from the outside, but an electric heater is installed under the parapet. .

  However, as in Patent Documents 1 and 2, in the case of adopting a structure in which a heater is provided under a so-called roofing board, when a roof heater is installed, a professional craftsman who works the roof and a professional craftsman who performs electrical work In other words, the work schedule adjustment is complicated, and not only can the work be performed quickly, but also the installation cost of the snow melting heater is inevitably increased.

  Therefore, a mat-shaped snow melting heater material that can be easily installed on a metal plate such as a tin roof has been proposed (Patent Document 3). This uses a sheet heater in which a heating electrode wire is arranged on a resin sheet material, and a magnet sheet is arranged on the back surface thereof. When energized, the seat heater generates heat, and a magnetic sheet is provided on the back surface, so that it can be easily installed on a tin roof or metal headboard.

  By the way, the mat-shaped snow melting heater of Patent Document 3 cannot cope with concrete or mortar surfaces such as a rooftop of a building, so there is still room for improvement.

  Therefore, an object of the present invention is to provide a mat-shaped snow melting heater device that can be installed on a concrete surface or a mortar surface.

  In order to achieve the above object, a snow melting heater material according to the present invention covers the surface of a sheet heater in which a heating electrode wire is arranged on a flexible resin sheet material with a thin flexible insulating waterproof material. A flexible pressure-sensitive adhesive sheet material is provided on the back surface of the sheet heater, and the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet material is covered with a detachable thin release material (Claim 1).

  Since it has a flexible heater structure and an adhesive sheet material is provided on the back surface, it can be used for a wide range of applications such as a concrete surface on a building roof, a residential wall such as concrete or mortar, and a glass surface. If the sheet heater (including a film heater) is energized, ice and snow can be melted by the sheet heater, which is a heating element, so that sophisticated electrical work is not required. This is because it is only necessary to expose a harness (electric wire) for supplying power to the seat heater to the outside and plug the terminal outlet into the power source. Since it is flexible, it can respond flexibly even if there are irregularities in the surface material, and it has excellent adsorption performance and can guarantee high heat conduction performance. Moreover, since it can respond also to a metal surface, versatility increases remarkably.

  According to a second aspect of the present invention, the seat heater is one of a sheet heating element and a line heating element.

  The sheet heating element generates heat from the sheet heater by the electrode wire, and has an advantage that the heat generation state can be maintained and the snow melting can be continued even when the electrode wire is cut, but there is a concern of abnormal heat generation. Since the wire surface heating element has a transverse conductive yarn (electric resistance wire) spanned between an appropriate number (for example, two) of electrode wires, it becomes difficult to maintain the heat generation state when the electrode wires are broken due to deterioration or the like. However, there is an advantage that accidents due to abnormal heat generation can be reliably prevented. It is desirable to properly use the sheet heating element and the line heating in consideration of the amount of snowfall, the roof structure, the material and structure of the building, and the like.

  In some cases, a self-control heater wire is provided in the longitudinal direction of the rectangular sheet heater.

  The snow melting heater material according to the present invention may have any external shape when viewed from a plane. However, in the case of a rectangular type that is frequently used, by providing a self-control heater wire in the longitudinal direction of the seat heater, Kasagi It is possible to prevent icicles that occur in Although it is possible to use the seat heater itself as a self-control heater material, if a wide self-control heater material is used, the product cost tends to increase, so a self-control heater wire is provided in the longitudinal direction of the seat heater. It is desirable to keep it.

  The snow melting heater material according to the present invention can cope with various floor surfaces such as concrete surfaces, mortar surfaces, metal surfaces, vertical walls, and the like. Almost no electrical work related to wiring facilities is required. Since it is possible to easily melt snow in the required area and location, it is possible to easily melt snow even in places where it is difficult to install snow melting equipment for technical and cost reasons.

It is a perspective view which illustrates the snow melting heater material which concerns on 1st embodiment. It is sectional drawing of the snow melting heater material of FIG. It is a figure which shows the example of application of the snow melting heater material of FIG. It is a figure which illustrates the snow-melting heater material which concerns on 2nd embodiment. It is a figure which illustrates the snow melting heater material which concerns on 3rd embodiment.

  1 and 2 illustrate a snow melting heater material according to the present invention. The snow melting heater material H includes a flexible adhesive sheet material 14 disposed on the back surface of the seat heater 10 and a flexible thin insulating waterproof material 17 disposed on the surface of the seat heater 10.

  The sheet heater 10 uses, for example, a planar heating element. 11 is a sheet material of a sheet heating element, and 12 is two electrode wires arranged on the sheet material 11. This sheet heating element is a resistance heating element in which the sheet material 11 has conductivity, and when the two electrode wires 12 are energized, the sheet material 11 generates heat. Therefore, for example, a flexible carbon sheet is used as the sheet material 11. The size of the seat heater 10 is appropriately set according to the application location.

  The adhesive sheet material 14 disposed on the back surface of the sheet heater 10 is desirably as thin as possible, for example, having a thickness of 3 mm or less in order to ensure the flexibility of the snow melting heater material H as a whole. Locations that require snow melting in winter, such as the concrete shop upper surface and the concrete wall surface, are generally smooth and have no irregularities that damage the adhesive sheet material 14. Therefore, for example, even if a thin adhesive sheet material 14 having a thickness of about 0.5 to 1 mm is used, there are almost no practical problems.

  The pressure-sensitive adhesive sheet 14 includes a thin base sheet 14-1, an adhesive layer 14-2, and a release paper 14-3 that covers the adhesive layer 14-2.

  The adhesive used for the adhesive layer 14-2 is selected from those having good adhesive compatibility with an object to be bonded such as concrete or mortar, or those having good adhesive compatibility with the base material provided on the object to be bonded such as concrete or mortar. And use it. The base material disposed on the object to be bonded is not limited to the case where an appropriate resin coating material is applied. This is because, for example, a coating material such as resin, wood, or metal may be disposed on the surface of the object to be bonded, and the adhesive sheet material 14 may be adhesively disposed thereon.

  The release paper 14-3 is not limited to paper and may be a resin thin sheet material. It is possible to cover the entire surface of the adhesive layer 14-2 at normal times without damaging the adhesive layer 14-2, and to peel it without resistance when peeling off, so that the adhesive layer 14-2 can be exposed. good. Depending on the compatibility with the adhesive used for the adhesive layer 14-2, an appropriate release material that is easy to peel off is selected and used.

  The insulating waterproof material 17 electrically insulates the electrode wires 12 disposed on the seat heater 10 and prevents the intrusion of water into the interior. In order to ensure flexibility, a sheet material formed of an elastic resin material such as butyl rubber, vinyl chloride, or polyethylene is used. It is desirable to make the wall thickness as thin as possible. For example, it is 1-5 mm. This is because it is desirable to minimize the loss of heat generated by the seat heater 10 in a place where it is difficult to receive external disturbances.

  Therefore, according to the snow melting heater material H, it is possible to easily stick and arrange it on a place where snow melting has been difficult in the past, for example, on the roof surface R of the building, particularly on the concrete surface below the parapet P as shown in FIG. The snow can be melted by supplying power to the seat heater 10.

  In snowy areas, a large amount of snow is piled up on the rooftop R of the so-called snow-free houses and the rooftop R of the building, and a snow leopard is formed over the parapet P. Various technologies have been proposed due to problems such as damage to or damage to pedestrians and automobiles, but snowfall can be achieved by placing the snow melting heater material H according to the present invention under the parapet P of various buildings. It will be possible to easily solve the snow jar problem that was a winter problem on the ground.

  In addition, the snow melting heater material H can be attached to places such as walls of ordinary houses, vertical walls of large-scale facilities, vertical walls of various facilities, and the like that cause problems peculiar to snowfall due to the attachment of ice and snow. For this reason, various ice and snow problems that have conventionally been solved individually by expensive special construction can be solved more easily and at low cost.

  The snow melting heater material H according to the present invention is flexible as a whole. Thereby, even when the laying surface is uneven or curved, it can be flexibly dealt with and easy and reliable in arrangement.

  As shown in FIG. 4, the sheet heater 10 according to the present invention uses a line surface heating element in which two electrode wires 22 are provided on a non-conductive sheet material 21 and a large number of transverse conductive yarns 24 are provided between the electrodes. May be. In the line surface heating element, when the electrode wire 22 is cut, the horizontal conductive yarn 24 is not energized, and thus there is no abnormal heat generation.

  Further, as shown in FIG. 5, the snow melting heater material H may be provided with a self-control heater wire 20 along the longitudinal direction of the sheet heater 10 having a substantially rectangular shape. When the self-control heater wire 20 that changes the energization amount according to the outside temperature is provided, for example, even when it is attached to a rain and snow cover that covers the upper part of the ticket issuing device in a parking lot or an expressway, a minimum electric power Consumption prevents icicle growth and eliminates complaints from users in winter.

  Even when a planar heating element is used, abnormal heat generation can be prevented by using a current regulator and a voltage regulator that control the current value of the power supply. If such an adjuster is used, the temperature of the snow melting heater material H can be kept at a relatively low temperature (for example, a surface temperature of about 50 ° C.). Needless to say, the on / off control of the snow melting heater material H may be switched using a snowfall sensor or an outside air temperature sensor. Manual on / off control may be used.
