PROBLEM TO BE SOLVED: To provide a fire resistant structure of balcony capable of increasing the fire resistance efficiency of a balcony floor.SOLUTION: A balcony floor 2 comprises beams 8 and 9 which support a floor part 5 located in an outdoor side edge part of the balcony floor 2 and constituting a floor surface and which are covered by a plurality of fire resistive covering materials 11, 12, 13 and 14. The beams 8 and 9 comprise an outdoor side vertical surface W1 facing the outdoor side. The plurality of fire resistive covering materials 11, 12, 13 and 14 include a first fire resistive covering material 11 which covers the outdoor side vertical surface W1 of the beams 8 and 9, and in the beams 8 and 9 a plurality of holding members 15 are arranged and fixed in a space with the outdoor side vertical surface W1 through the first fire resistive covering material 11 and at intervals along a lengthwise direction of the beams 8 and 9.SELECTED DRAWING: Figure 1 |
