PROBLEM TO BE SOLVED: To provide a free access floor and a cooling and heating system that allows easy access to underfloor after installation.SOLUTION: A free access floor 1 has a floor board 10 which is placed on a foundation floor B with a space between them, and a floor structure member 20 supporting the floor board 10. The floor structure member 20 has a frame part 21 supporting a circumference of the floor board 10 and leg parts 29 in contact with the foundation floor B and supporting the frame part 21. A through hole 21h enabling access to the foundation floor B from above is formed inside the frame part 21. A floor board 10 is detachably formed on the frame part 21. When the floor board 10 is mounted on the frame part 21, the through hole 21h is covered. Thus, easy access to underfloor is realized without moving the floor structure member 20, after the free access floor 1 is laid on the foundation floor B. A cooling and heating system comprises the free access floor 1 and an air temperature controller that controls the temperature of air supplied to a rear side space between the floor board 10 and the foundation floor B.SELECTED DRAWING: Figure 1 |
