PROBLEM TO BE SOLVED: To provide a collapsible floor heating panel to be collapsible longitudinally and laterally, facilitate a folding work and an unfolding work, thus be easy in handling during packing, transportation, storage, and laying. SOLUTION: In first invention, a plurality of plane-form or oblong-shaped small plate-form substances are situated in an adjacent state longitudinally and laterally, and a flexible sheet is stacked on the upper surfaces of the plate- form substances and longitudinal and lateral folding is practicable. A passage for a flexible tube for a heating medium is situated at a longitudinally and laterally folded part with a play. The so formed collapsible floor heating panel is characterized in that a folding margin member is located at the laterally folding part. In the second invention, a fitting-in member is situated in the passage provided with a play for each flexible tube for a heating medium. |
