PROBLEM TO BE SOLVED: To provide concrete floor heating equipment at a low cost without increasing the floor thickness. SOLUTION: After the arrangement of a lower frame plate (20) and side frame plates (21 and 22), the first to ninth reinforcing bars (110 to 190) and a hot-air blower (300) are arranged. After that, the first to eighth transverse hollow pipes (210 to 280) are arranged. The left end of the eighth transverse hollow pipe is coupled with the reflux opening (320) of the hot-air blower, and the upper end of the first longitudinal hollow pipe (291) is coupled with the air outlet (310) of the hot-air blower. A connection is made between the lower end of the first longitudinal hollow pipe and the right end of the eighth transverse hollow pipe through a bent pipe (295), the second portion (222) of the second transverse hollow pipe (220), the bent pipe, the second longitudinal hollow pipe (292), the bent pipe, the second portion (242) of the fourth transverse hollow pipe (240), the bent pipe, the third longitudinal hollow pipe (293), the bent pipe, the second portion (262) of the sixth transverse hollow pipe (260), the bent pipe, the fourth longitudinal hollow pipe (294) and the bent pipe, so as to complete heating medium piping. After that, concrete is placed.
