PROBLEM TO BE SOLVED: To facilitate formation of a fire-resistant coating by inserting a wire constituting a string beam structure or a hanging structure into the inside of an outer peripheral member tubularly formed and filling a fire-resistant coating material between the outer peripheral member and the wire. SOLUTION: When a lower chord material 6 is laid between bothe ends of a roof, the lower chord material 6 is constituted so that a round steel (wire) 10 is inserted in a steel pipe (outer peripheral member) 11 and further, a ceramic-based fireresistant coating material 12 is filled in between the steel pipe 11 and the round steel 10. The lower chord material 6 is obtained by fixing the position of the round steel 10 in the steel pipe 11 and further, filling the fire resistant coating material 12 between the steel pipe 11 and the round steel 10. Such a fire resistant coating material may be used for not only the lower chord member but also a hanging member for a hanging structure. Accordingly, even when anchorage between the wire and the fire resistant coat is not favorable, the fire resistant coat can be easily formed, and as the fire resistance coating material is invisible in the appearance because it is covered with the outer peripheral members, a favorable design effect can be secured.
