PURPOSE: To easily, speedily and economically construct a high quality free access floor by making a floor panel for a heavy load by way of laminating an iron plate for reinforcement on a lower surface of a floor panel for a light load. CONSTITUTION: A steel made floor panel 3 for a light load composited by laminating a flat upper iron plate 30 and a lower iron plate 31 having a plural number of dome type projections 8... is set on supports 2, 2 of a light load floor zone cut of a free access floor 6. Additionally, a steel made floor panel 5 for a heavy load composited in a state free to transmit tensile force by laminating a flat iron plate 4 for reinforcement on a lower surface 31a... of the lower iron plate 31 of the floor panel 3 for the light load is set on the support 2 of a heavy load floor zone. Thickness of the floor panel 3 for the light load and the floor panel 5 for the heavy load at portions to set them on the support 2 is formed same. Consequently, specifications for the floor panels 3, 5 for the heavy load and the light load become almost common, and treatment of height adjustment becomes unnecessary. |
