PURPOSE:To safely and exactly support a platform by fixing the outer plate of a column extended to beam parts through the deck of a floating body at the contact point between the deck and the beam parts. CONSTITUTION:The outer plate 21 of a column (pillar) 2 is extended to a beam part 6 supported by a beam pole 5 through the deck 3 of a floating body (pontoon) 1, and the outer plate 21 is fixed at the contact point 7 with the deck 3 and the contact point 8 with the beam part 6. Even when the force (arrow mark) in the thick wise direction of the plate is applied, since the force is shared by the outer plate 21, the occurrence of lamellar-tiering phenomenon in the deck 3 can thus be prevented, and also since the column 3 is strongly fixed to the pontoon 1, the platform can be supported safely and exactly. Therefore, the separation in the thickwise direction of the steel plate can be prevented. |
