Description

  The present invention relates to a roof snow melting mat installed on a roof.

  A roof snow melting mat that is laid on a roof and melts snow (snow) with heat from an internal heat source (electric heater) is widely known. As the electric heater, a planar heater (Patent Documents 1 and 2) and an electric heating wire (Patent Documents 3, 4, and 5) are employed.

  In addition, as the sheet main body for protecting the heater, synthetic resin, nonwoven fabric, woven fabric (Patent Document 4), rubber sheet (Patent Document 5), and the like are employed.

  Further, the snow melting mat is installed on the roof, and if it is simply installed, it is blown up or blown away by the wind.

  Therefore, as a means for fixing a snow melting mat, Patent Document 3 discloses an L-shaped bracket in which the mat is formed of a thin sheet (woven fabric sheet), the end surface of the mat is sewn into a cylindrical shape, and a weight is attached to the cylindrical portion. I am trying to wear it.

  Further, in Patent Document 4, a small hole is formed in a peripheral portion of a thin sheet (woven cloth sheet) forming a mat, and the small hole is used to connect to an adjacent mat or hang from a peak of a roof. A structure is disclosed.

Registered Utility Model No. 3092067. JP 2001-248272 A. Japanese Utility Model Laid-Open No. 3-101765. JP-A-8-28094. JP 2000-38702 A.

  As described in Patent Documents 3 and 4, when the insulation-covered heating wire is matted by covering the front and back with a thin woven cloth-like sheet, the tubular locking portion is formed by stitching as described above. It is easy to drill small holes, but the top surface of the snow-melting mat is uneven, so snow that falls naturally and does not need to melt naturally will remain on the roof as it melts. There is a problem in terms.

  On the other hand, for example, as described in Patent Document 5, if the heating wire is covered with a thick rubber sheet on both sides and the surface is made smooth, the problem of the snow melting mat formed with the mat-like sheet is solved. However, a complicated manufacturing operation is required to provide a structure such as providing a large number of small holes on the periphery for roof installation.

  Therefore, the present invention proposes a laying structure that can be easily incorporated in a snow melting mat formed of a rubber sheet.

  The roof snow melting mat according to the present invention has a heat insulating wire which is insulated and coated on a synthetic rubber base portion having an appropriate thickness, and the entire surface or part of the heating wire is a heat radiating portion made of aluminum foil. Cover and cover the entire top surface with a synthetic rubber surface portion of appropriate thickness and adhere to the base portion to form a mat body. At the time of bonding the base portion to the surface portion, a thin film having a predetermined flexibility is provided. The sheet is folded in a U shape, and the folded base portion is sandwiched and bonded between the surface portion of the periphery of the mat body and the base portion, and a cylindrical locking portion is provided on the outer periphery of the mat body.

  Thus, when the snow-melting mat is laid on the roof and the suspension member having one end connected and fixed to the roof is inserted into the cylindrical locking portion, the snow-melting mat is attached to the roof. Movement (sliding down, rolling, etc.) is prevented.

  According to the present invention (Claim 2), the mat body has a narrow rectangular shape, and is provided with a cylindrical locking portion on a long edge.

  Therefore, the snow-melting mat can be laid and fixed transversely (parallel to the peak) near the upper peak on the roof surface, and the snowfall (snow) on the mat is melted by the heat of the mat, and As a result, snowfall (snow) on the roof hem will be melted, realizing energy saving of roof melting. Moreover, since it is easy to wind up and fold a mat body as it is narrow-width rectangular shape, it is convenient for storage handling.

  Since the present invention adopts the above-described configuration, in the snow melting mat in which the base portion and the surface portion of the mat body are formed by the rubber sheet, the cylindrical engagement is performed at the same time when the base portion and the surface portion are integrated. Since the stop portion is provided, the engagement portion can be easily formed, and the rubber snow melting mat can be safely and reliably laid on the roof.

  Next, an embodiment of the present invention will be described. The roof snow melting mat shown in the embodiment is composed of a base portion 1, an electric heating portion 2, a heat radiating portion 3, a surface portion 4 (the mat body is formed as described above), and a cylindrical locking portion 5.

  The base portion 1 has a width of about 50 to 120 cm, a narrow rectangular shape with a length of several meters, and is made of synthetic rubber having an appropriate thickness (determined by the strength of the mat body).

  The heating section 2 includes a heating wire 21 with an insulating coating, a lead portion 22 formed of a lead wire connected to the heating wire 21, and a connection portion (socket portion connected to an external power source) 23. The heating wire 21 is appropriately detoured on the base portion 1. The detour shape and arrangement position are appropriately determined in consideration of the heat generation capability of the heating wire 21. Moreover, the connection part 23 is provided in a short edge so that external connection may be made easily.

  The heat dissipating part 3 is formed of aluminum foil, and adheres to a part of the heating wire 21, a part of the whole detouring range, or the entire surface of the base part 1 (except for the engaging part pasting periphery described later). Glue and coat with agent.

  The surface portion 4 has a shape corresponding to that of the base portion 1 and is bonded to the upper surfaces of the base portion 1 and the heat radiating portion 3 to cover the entire upper surface. Is also formed.

  The cylindrical locking portion 5 is formed by folding a thin sheet with appropriate flexibility such as a rubber thin sheet, a work cloth such as a tent, and a rubber-coated woven fabric into a U shape, and a folded base portion with the base portion 1. When the surface portion 4 is bonded, it is sandwiched and bonded to the periphery of the mat body, and a cylindrical portion is formed on the outer periphery of the mat body. In particular, the cylindrical locking portion may be continuously provided on the entire circumference, but may be formed only on the long edge in consideration of roof laying fixation.

  Further, when forming a cylindrical shape continuous with all of the edges, it is possible to continuously hold and bond the base portion 1 and the surface portion 4, but when forming intermittently, the material of the locking portion However, it is troublesome in manufacturing because it is necessary to align and hold the independent locking portions together.

  Thus, the snow melting mat is wound and folded when stored, and is laid and fixed on the surface of the roof A in the winter. The installation location is transverse to the position close to the peak on the roof A (parallel to the peak). In the cylindrical locking part 5 laid on the upper side, a wire rope is passed or a wire rope for hanging the end is tied through a metal rod, and each of the wire ropes B has a mat body. The end part is tied to the appropriate part of a building so that it may hang from a part direction. Further, a wire rope may be inserted into the cylindrical locking portion 5 located below and fixed to a roof shape, or a metal rod serving as an appropriate weight may be attached.

  When the mat body is laid and fixed in a roof shape in this way and the external power line C is connected to the connection portion 23, the entire mat body is warmed by the heat radiation of the heating wire 31, the snow on the mat is dissolved, and the snow melting water It melts the snow on the roof hem.

  Therefore, it is possible to melt snow on the entire roof without laying a mat body on the entire roof.
