Description

金属屋根およびビルの笠木部や橋など構築物の融雪装置の技術に関するものである。   This invention relates to the technology of snow melting equipment for structures such as metal roofs, building headboards and bridges.

従来の金属屋根およびビルの笠木部分などの融雪装置は、融雪しようとする板金の下に融雪用熱源を直接敷設する方法、または露出配管に融雪用熱源を供給する方法がとられている。これらの方法は熱源に近い融雪面の積雪は急速に融かすことが出来るが、この熱源に近い積雪が融けた部分から冷えた大気に熱エネルギーが散逸して損失となるため、熱源から離れた融雪面の積雪が融けないで残る融雪むらが生じ効率が良くない。（例、特許文献1参照）
図1は、例として従来の金属屋根の融雪装置を示す断面図である。
下地板6の上に、融雪用熱源1が収まる凹みを設けた下地断熱材5を敷設し融雪用熱源1と板金4と直接蜜着するように敷設している、このため融雪用熱源1に電熱線または温水などの熱源を通すと、熱源に近い融雪面7の積雪はすぐ溶ける。
しかし、積雪の融けたこの熱源に近い融雪面7から多くの熱エネルギーが冷えた大気に散逸して、融雪用熱源1から離れた融雪面8には積雪15が溶けないで残る融雪むらが生じている。 A conventional snow melting device such as a metal roof and a headboard portion of a building employs a method of directly laying a heat source for melting snow under a sheet metal to be melted, or a method of supplying a heat source for melting snow to an exposed pipe. Although these methods can quickly melt snow on the snow melting surface near the heat source, heat energy is dissipated and lost from the melted snow near the heat source to the cold atmosphere, so it is far from the heat source. The snow melt unevenness that remains without melting the snow on the snow melting surface is generated and the efficiency is not good. (For example, see Patent Document 1)
FIG. 1 is a cross-sectional view showing a conventional snow melting apparatus for a metal roof as an example.
On the base plate 6, the base heat insulating material 5 provided with a recess for accommodating the snow melting heat source 1 is laid so as to be directly attached to the snow melting heat source 1 and the sheet metal 4. When a heat source such as a heating wire or hot water is passed, the snow on the snow melting surface 7 near the heat source melts immediately.
However, a large amount of heat energy is dissipated from the snow melting surface 7 near the heat source where the snow melted to the cold atmosphere, and the snow melting unevenness that remains without melting the snow 15 occurs on the snow melting surface 8 away from the heat source 1 for snow melting. ing.

特許公開2002−356959号、特許公開2003−82882号、Patent Publication 2002-356959, Patent Publication 2003-82882,

従来の金属屋根及びビルの笠木などの融雪装置において、融雪面の積雪が融けると融雪用熱源に近い部分の温度が一番高いため、この融雪面から多くの熱エネルギーが冷えた大気に散逸して熱エネルギーが損失している、この熱エネルギーの損失を抑制して熱エネルギーを広く伝熱して効率よく融雪することを課題としている。   In conventional snow melting equipment such as metal roofs and building caps, when the snow on the snow melting surface melts, the temperature near the heat source for melting snow is the highest, so much heat energy is dissipated from the snow melting surface to the cold atmosphere. The heat energy is lost, and this heat energy loss is suppressed, and the heat energy is widely transferred to efficiently melt the snow.

本発明は上記目標を達成するため、融雪用熱源に熱伝導率の良いアルミ等の金属板を取付け熱エネルギーを広く伝熱させ、また融雪用熱源と融雪面の板金の間の一部に薄い断熱材を半断熱材として貼付け熱エネルギーが冷えた大気に散逸して損失することを防ぐ融雪装置を提供するものである。   In order to achieve the above-mentioned goal, the present invention attaches a metal plate such as aluminum having good thermal conductivity to the heat source for melting snow to transfer heat energy widely, and is thin in a part between the heat source for melting snow and the sheet metal on the snow melting surface. The present invention provides a snow melting device that uses heat insulating material as a semi-insulating material to prevent heat energy from being dissipated and lost in a cold atmosphere.

同じ熱エネルギー量で従来の方法に比べ雪の融ける面積を１６０％以上広く融雪することが出来た。   With the same amount of heat energy, it was possible to melt snow more than 160% wider than the conventional method.

次に、本発明の実施の形態について説明する。 Next, an embodiment of the present invention will be described.

図2は熱伝導と半断熱効果を併用した融雪方法の断面図である。
この熱伝導と半断熱効果による融雪装置は、金属屋根及びビルの笠木部分や橋などの構築物の着雪着氷する部分に応用することができる。
図2では金属屋根の融雪装置を例として説明する。
下地板6の上に下地断熱材5を設けこの下地断熱材5に凹み部9を設ける。そしてこの凹み9に融雪用熱源1と熱伝導の良い金属板2を蜜着して敷設する、また融雪用熱源近くの熱伝導の良い金属板2に一定の幅に切断した半断熱材3を貼付け板金４の下に設置する。 FIG. 2 is a cross-sectional view of a snow melting method using both heat conduction and a semi-insulating effect.
The snow melting device by this heat conduction and semi-insulating effect can be applied to a portion of a metal roof and a building such as a headboard portion of a building or a snow landing on a structure such as a bridge.
In FIG. 2, a metal roof snow melting device will be described as an example.
A base heat insulating material 5 is provided on the base plate 6, and a recess 9 is provided in the base heat insulating material 5. In addition, a snow melting heat source 1 and a metal plate 2 with good heat conduction are laid in this recess 9 and a semi-insulating material 3 cut to a certain width is attached to the metal plate 2 with good heat conduction near the heat source for snow melting. Install under the sheet metal 4.

次にこの融雪装置の作用について説明する。
融雪用熱源1に電熱線または温水などの熱源を通すと、熱エネルギーの一部は半断熱材3を貫通して板金4の熱源に近い融雪面7を加熱してこの部位の雪を融雪する、
しかし熱源に近い融雪面7の積雪が融けるが融雪用熱源1と板金4の間に半断熱材3が存在するため、融雪用熱源1の熱エネルギーが冷えた大気に散逸して損失することを抑制することができる。
このため、もう一方の熱エネルギーは融雪用熱源1から熱伝導の良い金属板2を伝熱して板金4の熱源から離れた融雪面8を加熱してこの部位の雪を融雪することができる。
このように、融雪用熱源1と板金4の間に半断熱材3を設けることで熱エネルギーが融雪用熱源に近い融雪面7から熱エネルギーが大気に散逸することを抑え、熱伝導の良い金属板２の伝熱効果で熱エネルギーを広く伝熱して効率よく融雪する装置である。 Next, the operation of the snow melting device will be described.
When a heat source such as a heating wire or hot water is passed through the heat source 1 for melting snow, a part of the heat energy penetrates the semi-insulating material 3 and heats the snow melting surface 7 near the heat source of the sheet metal 4 to melt the snow of this part. ,
However, although the snow on the snow melting surface 7 close to the heat source melts, the semi-insulating material 3 exists between the snow melting heat source 1 and the sheet metal 4, so that the heat energy of the snow melting heat source 1 is dissipated and lost to the cold atmosphere. Can be suppressed.
For this reason, the other heat energy can be transferred from the snow melting heat source 1 to the metal plate 2 having good thermal conductivity, and the snow melting surface 8 away from the heat source of the sheet metal 4 can be heated to melt the snow at this portion.
Thus, by providing the semi-insulating material 3 between the snow melting heat source 1 and the sheet metal 4, the heat energy is prevented from being dissipated into the atmosphere from the snow melting surface 7 close to the snow melting heat source, and the metal has good heat conduction. The heat transfer effect of the plate 2 is a device that transfers heat energy widely and efficiently melts snow.

図９は融雪面の温度分布グラフである。
従来の融雪方法による融雪面の温度分布グラフ１９と本発明による融雪面の温度分布グラフ２２を示している。
グラフ横軸１７は融雪用熱源の点１６から左右に離隔する融雪面の距離を表し、グラフ縦軸１８は板金４の融雪面各点の温度上昇を示している。
この温度分布グラフが示すように、従来の融雪方法の温度分布１９は融雪用熱源の点の温度２０が高い温度を示すが熱源の点１６から離隔した点の温度２１が急に低くなっている。
これと比較して、熱伝導と半断熱効果を併用した本発明による融雪装置では融雪用熱源の点の温度２３は半断熱材３の効果で低い温度を示していて、熱源の熱エネルギーが冷えた大気に散逸して損失することを抑制している。
一方、熱伝導の良い金属板２の熱伝導効果で熱源から離隔した点の温度２４が高い温度を維持できるため積雪を広く融雪できることを示している。 FIG. 9 is a temperature distribution graph of the snow melting surface.
The temperature distribution graph 19 of the snow melting surface by the conventional snow melting method and the temperature distribution graph 22 of the snow melting surface according to the present invention are shown.
The horizontal axis 17 of the graph represents the distance of the snow melting surface that is separated from the point 16 of the heat source for melting snow to the left and right, and the vertical axis 18 of the graph indicates the temperature rise at each point of the snow melting surface of the sheet metal 4.
As shown in this temperature distribution graph, the temperature distribution 19 of the conventional snow melting method shows a high temperature 20 at the point of the snow melting heat source, but the temperature 21 at a point separated from the point 16 of the heat source suddenly decreases. .
In comparison with this, in the snow melting device according to the present invention using both heat conduction and a semi-insulating effect, the temperature 23 at the point of the heat source for melting snow shows a low temperature due to the effect of the semi-insulating material 3, and the heat energy of the heat source is cooled. To prevent loss to the atmosphere.
On the other hand, the temperature 24 at the point separated from the heat source can be maintained at a high temperature by the heat conduction effect of the metal plate 2 having good heat conduction, which indicates that snow can be melted widely.

このデータを基に同じ熱エネルギーを使用して融雪試験を実施した結果、従来の板金４に直接融雪用熱源を敷設する方法に比較して、本発明による融雪方法が約１６０％以上の融雪能力を得ることができた。   As a result of the snow melting test using the same heat energy based on this data, the snow melting method according to the present invention has a snow melting capacity of about 160% or more compared to the conventional method of laying a snow melting heat source directly on the sheet metal 4. Could get.

FIG. 4 is a cross-sectional view AA of the heat conductive plate 10 with a semi-insulating material.
A recess was provided in the metal plate 2 with good heat conductivity cut to a predetermined length of a certain width, and the heat source pipe 11 was attached thereto, and the semi-insulating material 3 was pasted into the recess of the metal plate 2 with good heat conductivity. Of structure.

図5は半断熱材付熱伝導板１０と板金４の斜視図である。
この図５に於ける、半断熱材付熱伝導板10と板金4の作用について説明する。
熱源用パイプ11に電熱線または温水などの熱源を通すと熱エネルギーの一部は半断熱材3を貫通して板金4の熱源に近い融雪面7の積雪を融雪する、またもう一方の熱エネルギーは熱源を通すパイプ11から熱伝導の良い金属板2を経て、板金4に伝熱して熱源から離れた融雪面8の積雪を融雪する。
この場合、熱源に近い融雪面7の積雪が融雪しても半断熱材3の半断熱効果で熱エネルギーが冷えた大気に散逸して損失することを抑制するため、もう一方の熱エネルギーが熱源から離れた融雪面8の積雪を融雪することが出来るのである。 FIG. 5 is a perspective view of the heat conductive plate 10 with a semi-insulating material and the sheet metal 4.
The operation of the heat conductive plate 10 with a semi-insulating material and the sheet metal 4 in FIG. 5 will be described.
When a heat source such as a heating wire or hot water is passed through the heat source pipe 11, a part of the heat energy melts through the semi-insulating material 3 and melts snow on the snow melting surface 7 close to the heat source of the sheet metal 4, and the other heat energy Passes through the metal plate 2 having good heat conduction from the pipe 11 through which the heat source passes, transfers heat to the sheet metal 4 and melts snow on the snow melting surface 8 away from the heat source.
In this case, even if the snow melt on the snow melting surface 7 close to the heat source melts, the other heat energy is used as the heat source in order to suppress the heat energy from being dissipated and lost to the cold atmosphere due to the semi-insulating effect of the semi-insulating material 3. It is possible to melt snow on the snow melting surface 8 away from the snow.
