To provide a snow melting block device that prevents damage to a connecting part between a main pipe and a branch pipe made of polyvinyl chloride that thermally expand and contract in the pipe axis direction due to a temperature change during concrete solidification.SOLUTION: A snow melting block device comprises: a plurality of sprinkler nozzles that are buried on the upper surface of a concrete snow melting block, so as to be flush therewith, at prescribed intervals; a PVC main pipe 2 arranged in the longitudinal direction inside the snow melting block; a plurality of branch pipes 3 connected to the sprinkler nozzle from the main pipe 2; and a connecting pipe 4 having a flow hole 41 communicating with the branch pipe 3 from the main pipe 2. A cylindrical cover member 5 made of an elastic material is fitted to the connecting pipe 4. A lower end surface 5a of the cover member 5 has a curved shape along an outer peripheral surface 2b of the main pipe 2. The lower end surface 5a abuts on the outer peripheral surface 2b of the main pipe 2.SELECTED DRAWING: Figure 3
【課題】コンクリート固化時の温度変化により管軸方向に熱伸縮するポリ塩化ビニール製の主管と枝管との連結箇所の破損が防止される消雪用ブロック装置を提供する。【解決手段】コンクリート製の消雪用ブロックの上面に面一状態で所定間隔をおいて埋設される複数の散水ノズルと、前記消雪用ブロックの内部に長手方向に配置するポリ塩化ビニール製の主管２と、この主管２より前記散水ノズルに接続する複数の枝管３と、よりなる消雪用ブロック装置であって、前記主管２より前記枝管３に連通する流通孔４１を有する連結管４を備え、前記連結管４に弾性材よりなる筒状のカバー部材５を被嵌し、前記カバー部材５の下端面５ａを前記主管２の外周面２ｂに沿う湾曲面形状とし、前記下端面５ａが前記主管２の前記外周面２ｂに当接する。【選択図】図３
