angle transverse to axis a because the cantilevered construction imparts resiliency in l shaped arm 46 44 the pedestal head 40 deforms such that distance d 2 becomes greater than distance d 1 as fastening element 60 continues to be tightened this deflection of the pedestal head 40 causes the interface between adjacent floor panels 50 to bow in a downward direction relative to the subfloor 20 again the amount of deflection illustrated in fig8 c has been exaggerated for illustration purposes but may be on the order of hundredths of an inch in practice after the fastening elements 60 have been secured to the pedestal head 40 a load can be applied to the bowed floor panels 50 by the installer to permanently deform the pedestal head 40 to the level configuration illustrated in fig8 a preferably the load is applied in a direction toward the subfloor 20 on an end of the panel 50 away from the pedestal head 40 thus in this manner the floor panels 50 can then be aligned in a level substantially horizontal position once the raised access floor system 10 has been completely installed and leveled the system 10 is rigid by virtue of the strength of the individual pedestal heads 40 and by the overall constraint of the interconnected system 10 the system 10 of interconnected floor panels 50 and pedestal heads 40 provide greater rigidity than is to be found in an individual pedestal head 40 alone in accordance with the present invention the floor panels 50 do not have to be secured to the pedestal heads 40 for example as described above where carpet or laminate is applied to the upper surface 52 of the floor panels 50 the.
