<P>PROBLEM TO BE SOLVED: To provide a frame for a free access floor or the like, which allows installation of heavy equipment on an upper part without amplifying vibrations from a floor, facilitates its installation and construction and allows reduction of the total height. <P>SOLUTION: A lower block 11 is provided with a lower frame connection part 12a and a lower plate connection part 12b. Between the lower frame connection part 12a and the lower plate connection part 12b, a step is formed. The lower block 11 is formed so as to project to an upper part of a support leg part 61, and interference of the lower block 11 and the support leg part 61 is prevented. Also, a height of the step of the lower frame connection part 12a and the lower plate connection part 12b is greater than a thickness of a head part of a bolt 9. Thus, in the state of fixing the lower block 11 to a lower plate 3, the head part of the bolt 9 is not projected above a connection surface of the lower frame connection part 12a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
