を設けたものである。That is, as shown in FIG. 3, the seasoning part 10 and the chain side part 1
1 constitutes the foundation of the staircase, and on top of the seasoning section 10 there is a heat insulating layer 129 and a mortar layer 13. The structure in which the outer layer 14 is provided and the heating wires 15 are buried in the mortar layer 13 is the same as the conventional one, but in the present invention, between the side surface of the mortar layer 13 and the chain side portion 11, elastic Side insulation layer 16
It has been established.
側面断熱層１６としては、例えばウレタンゴムのように
適当な弾力性と耐久性を有することが好ましく、また鎖
側部１１に接着されて取付けられてもよい。The side heat insulating layer 16 is preferably made of urethane rubber, which has appropriate elasticity and durability, and may be attached to the chain side portion 11 by adhesive.
また側面断熱層１６は背面に沿って設けられてもよい（
第４図参照）。Further, the side heat insulating layer 16 may be provided along the back surface (
(See Figure 4).

の侵入による熱効率の低下を防１卜する、二とか゛で゛
きる。As shown below, the snow melting staircase of the present invention can prevent heat dissipation to the side by providing an elastic side insulation layer between the side of the mortar layer and the chain side. Not only that, but also the adhesion between the chain side parts and the mortar layer is maintained, which prevents a decrease in thermal efficiency due to the intrusion of melted snow water.
なお、側面断熱層が鎖側部に接着されていれば、融雪水
の侵入による熱効率の低下を防止するのにさらに効果的
である。It should be noted that if the side heat insulating layer is adhered to the chain side part, it will be more effective in preventing a decrease in thermal efficiency due to intrusion of snowmelt water.
また、工場で予しめ発熱線下部の断熱層と側面断熱層と
