PROBLEM TO BE SOLVED: To provide a structure and a method for fixing a planking for a communication bridge between a quay wall and a floating body minimizing the influence of welding heat in view of causing a crack in concrete by the welding heat when fixing the steel planking laid at the floating body connected to the floating body side end of the communication bridge for connecting the floating body installed on the sea surface, to the quay wall.SOLUTION: Position anchors 21 are placed on a steel beam 2b, and concrete 12 is placed in a state of exposing upper end template parts 21a (Fig.2). A positioning groove 22 is formed around the embedded position anchors 21, and the rear face of the planking 20 is provided with a positioning flange part 20a inserted in the positioning groove 22. Mortar 23 is filled in the positioning groove 22 to insert the positioning flange part 20a. The planking 20 and the position anchors 21 are welded through welding through-holes 20b formed in positions, coinciding with the template parts 21a of the position anchors 21, of the planking 20. |
