FIRE RESISTIVE DEVICE FOR STRUCTURE

PROBLEM TO BE SOLVED: To provide a structure fire resistive device capable of maintaining fire resistance while having good abrasion resistance and maintenance. SOLUTION: A fire resistive joint sealing material 7 placed in a gap 5 between a pair of vertically separated fire preventive walls 1 and 3 includes a fire resistive core 9, a pair of supporting members 11 and 13, a pair of flame retardant members 15 and 17, a heating expansion fire resisting material 19, a pair of L-shaped metal fittings 21 and 23 as a fixed means and a plate-like metal fitting 25. The supporting members are provided to a corresponding side section of the fire resistive core, and they are separated from each other. The flame retardant members have flexibility and a line contact type, the front ends of them are respectively supported by the supporting members corresponding to them, and they are projected downward from the lower position of the fire resistive core. The heating expansion fire resisting material is provided to the inside of a space 35 demarcated by the fire resistive core and the flame retardant members.
