<P>PROBLEM TO BE SOLVED: To provide a floor structure in which, after a flooring base material using timber is spread, a height level of a supporting leg can be adjusted, increase in manufacturing costs and construction steps is suppressed, appearance is improved and safety is ensured. <P>SOLUTION: A floor structure comprises a plurality of floor support units 10 disposed on a foundation surface 2, a flooring base material 20 which is supported at a predetermined height level with respect to the foundation surface 2 by the floor support units 10, and a floor finish material 30 which is laid over the flooring base material 20. The floor support unit 10 includes a support bolt 13 which changes the height level of the flooring base material 10 with respect to the foundation surface 2 through rotation using a rotary tool 40. A joint dimension D between flooring base materials 30, 30 which are installed adjacently to spread over the floor support unit 20 is smaller than a diameter d<SB POS="POST">1</SB>of the support bolt 13 and larger than a diameter d<SB POS="POST">2</SB>of the rotary tool 40 which rotates the support bolt 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
