<p><P>PROBLEM TO BE SOLVED: To provide a hot water mat adopting an arrangement method of joists and a piping system of hot water pipes allowing adoption of the hot water mat to a room about 15 m<SP>2</SP>by using a conventional heat source unit. <P>SOLUTION: In a mat body 1, an upward crease line X-X' dividing the mat body 1 into a lower section area 3 and an upper section area 2 from a center as seen from above is formed between the areas, and downward crease lines Y-Y' are formed in key points so as to pass between the small joists 4a, 4b. The downward small joist 4a and the upward small joist 4b with tips from an upper edge and a lower edge of respective areas facing each other are respectively inserted in parallel with each other at a pitch of 303 mm in left and right directions excluding both left and right ends, and bridge parts 5 of hot water pipes 6a-6b are formed between respective tips of the small joists 4a, 4b. In the bridge parts 5, they are alternately disposed in a vertical direction in regard to adjacent bridge parts, intervals between upper and lower centers of the upper and lower bridge parts 5 are respectively set at 303 mm, and the hot water pipes 6a-6f are meanderingly disposed between the small joists 4a, 4b via the bridge parts 5. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
