Then, a state as shown in the sectional views of FIGS. 4 and 5 is obtained. The flooring board 14 is joined to another flooring board 14 by engaging the real part 14a and the groove part 14b.

As described above, in the floor heating combination panel directly laid and adhered to the upper surface of the concrete floor slab S, each of the panels 2 and 3 (the straight piping panel 2) is used.
Also, since the panel body 5 of the folded pipe panel 3) is formed of a material having heat insulating property, soundproofing property and sufficient compressive strength, the panel is compressed by a load placed on the indoor floor such as furniture or a pedestrian. It can be used in a stable state for a long time without deforming and sinking, and almost no impact sound generated when an object falls on the floor of the upper floor is transmitted to the lower concrete floor slab S. Not
Therefore, it does not affect the lower floors. In addition, the heat of the heat transfer plate 6 heated by the heat medium such as hot water flowing through the flexible tube 4 for flowing the heat medium can be effectively used by the heat insulating effect of the panel body 5.

A lower sheet 8 having soundproofness and flexibility capable of absorbing irregularities on the surface of the concrete floor slab S is mounted on the back surface of the panel body 5 of each of the panels 2 and 3. 8 can absorb the irregularities on the surface of the concrete floor slab S and adhere to it, and can be adhered to the floor slab S with an adhesive, so that floor noise can be prevented. Also, this lower sheet 8
Since the panel is formed of a soft foamed resin such as urethane foam, the soundproofing property and the heat insulating property of the panel can be further enhanced.

Further, as described above, since the panel body 5 itself has soundproofing properties and the lower sheet 8 mounted on the back surface of the panel body 5 has soundproofing and flexibility, the surface to be attached to the surface of the floor heating panel is provided. It is not necessary to provide a sound insulating material on the back surface of the finishing material. Therefore, the heat of the heat transfer plate 6 heated by the heat medium flowing through the flexible tube 4 for flowing the heat medium is transferred to the flooring board 14 as a surface finishing material. Can be quickly communicated.
