DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described.
This will be described with reference to FIGS. FIG. 1 (A), FIG.
As shown in FIG. 1, the floor heating device 1 (room temperature adjusting device) includes a square sheet assembly 10, two flow pipes 20 and a plurality of joists 30 fixed to the sheet assembly 10, and an edge of the sheet assembly 10. A connection unit 40 provided at both ends of the flow pipe 20.

The seat assembly 10 is shown in FIG.
As shown in (B), the heat radiation sheet 11 is made of aluminum and the cover sheets 12 and 13 made of a polyolefin resin such as polyethylene are laminated on the back side and the front side, respectively. The three sheets 11 to 13 are surface-bonded and integrated over substantially the entire area except for the fixing part of the flow pipe 20 and the joist 30 by means such as heat welding. Note that, as shown in FIGS. 1B and 2, the cover sheets 12 and 13
The area is larger, and the peripheral edges 12a and 13a (that is, four sides) are surface-bonded directly by means such as heat welding without interposing the heat radiation sheet 11. Thus, the heat radiation sheet 11 is closed.

The flow tube 20 is made of, for example, cross-linked polyethylene, is flexible, has a plurality of straight portions 20a parallel to each other, and has a meandering shape. The flow pipe 20 is sandwiched between the heat radiating sheet 11 and the cover sheet 12 on the back side, and is fixed to the heat radiating sheet 11 because the heat radiating sheet 11 and the cover sheet 12 are surface-bonded on both sides by heat welding or the like. It has been done. As a result, the desired interval between the linear portions 20a is stably maintained.

The joist 30 is made of wood and the flow pipe 2
0 are disposed between the straight portions 20a. This joist 30
Similarly to the flow pipe 20, the heat radiation sheet 11 and the back cover sheet 12 are sandwiched and fixed. In addition,
In the present embodiment, the height of the joist 30 is equal to the outer diameter of the flow pipe 20.

In the above-mentioned floor heating apparatus 1, the mat which has been commonly used until now is omitted, and on the back side of the seat assembly 10, between the adjacent straight portions 20a of the flow pipe 20, the straight line of the flow pipe 20 is provided. A space 50 is formed between the portion 20a and the joist 30. As is clear from the figure, the gap 50 has a width much larger than the diameter of the flow pipe 20. As described above, the floor heating device 1 is thinned because the place where the mat is conventionally placed is the gap 50, so that the floor heating device 1 can be compactly wound or folded. Also, the weight is lighter than when a mat is used. As a result, work such as transportation can be facilitated. The back cover sheet 12 has a role of fixing the flow pipe 20 to the heat radiation sheet 11. The front and rear cover sheets 12 and 13 reinforce the heat radiation sheet 11 to prevent the heat radiation sheet 11 from being damaged, and close the heat radiation sheet 11 so as to suppress corrosion due to long-term use.

The floor heating device 1 is used at a construction site.
