<P>PROBLEM TO BE SOLVED: To provide a floor panel, the deformation of which can be prevented by increasing its strength and which can prevent an increase in its weight and cost. <P>SOLUTION: A floor panel 20, in which mutual peripheral edges 22e and 24c of a top plate 22 and a box-shaped member 24 are connected together so as to form a space 26 therein, configures a free access floor structure 21 together with supporting legs 4 for supporting four corners of a bottom plate part 24a of the box-shaped member 24. Approximately quadrilateral protrusions 24e protruding to the opposite side of the top plate 22 with respect to other parts of the bottom plate part 24a are formed at the four corners of the bottom plate part 24a, respectively. A reinforcing member 28 is arranged between the top plate 22 and a part, except the protrusion 24e, of the bottom plate part 24a, and such a recess 24p as to be depressed with respect to the part, except the protrusion 24e, of the bottom plate part 24a is formed on the side, facing the top plate 22, of the protrusion 24e. The recess 24p is filled with a reinforcing filler member 30 which reinforces the box-shaped member 24 and the protrusion 24e so as to hardly cause deformation, when solidified. <P>COPYRIGHT: (C)2013,JPO&INPIT |
