상기와 같이 구성된 본 발명에 따른 발열 도금강판은 도금강판(30)의 정면에 그림, 문양(pattern) 등과 같은 이미지가 인쇄되어 있어, 이미지가 인물화나 풍경화 등의 명화일 경우, 도 1에 도시된 것처럼, 도금 강판(30) 자체를 액자 패널로 사용할 수 있으며, 일정한 패턴의 이미지일 경우, 도 4에 도시된 것처럼, 건물 내벽에 부착되는 패널 또는 욕실의 천장 패널 등으로 사용될 수 있다. 그리고, 도금강판(30)의 특성상 도금강판(30)은 PTC 필름(20)에서 발산하는 열을 외부로 방사하는 방열판 기능을 함으로써, 다른 건축 패널 보다 열을 더 효율적으로 잘 방사할 수 있어, 실내 보조 난방으로 사용되거나, 난방이 이루어지지 않고 있는 상가 화장실이나 외부 화장실의 내벽에 부착되는 패널 등을 사용될 수 있다. 이와같이 난방이 이루어지지 않고 있는 상가 화장실이나 외부 화장실의 내벽 패널 등으로 사용될 경우, 상가 화장실이나 외부 화장실에 동파 방지를 위해 별도로 히터 등을 설치할 필요가 없게 된다.In the heating plated steel sheet according to the present invention configured as described above, an image such as a picture or pattern is printed on the front of the plated steel plate 30, so when the image is a masterpiece such as a portrait or landscape, as shown in FIG. As such, the plated steel plate 30 itself may be used as a frame panel, and in the case of an image of a certain pattern, it may be used as a panel attached to an inner wall of a building or a ceiling panel of a bathroom, as shown in FIG. 4. In addition, due to the characteristics of the plated steel plate 30, the plated steel plate 30 functions as a heat dissipation plate that radiates the heat radiated from the PTC film 20 to the outside, so that it can radiate heat more efficiently than other building panels. It may be used as auxiliary heating, or a panel attached to the inner wall of a commercial toilet or external toilet that is not heated may be used. When used as an inner wall panel of a commercial toilet or external toilet that is not heated as described above, it is not necessary to separately install a heater or the like in the commercial toilet or external toilet to prevent freezing.

이때, 단열판(60)은 PTC 필름(20)의 열이 후방으로 방사되는 것을 방지하여, PTC 필름(20)의 열이 도금 강판(30)을 통해 외부로 방사되도록 유도한다.At this time, the heat insulating plate 60 prevents the heat of the PTC film 20 from radiating to the rear, so that the heat of the PTC film 20 is radiated to the outside through the plated steel plate 30.
