The utility model provides an inorganic fiber fire resisting shutter which comprises a shutter surface, a fastening device and a plurality of clamp plates. The shutter surface is formed by sequentially compounding an inorganic fiber decorative fabric, inorganic fiber cotton, an inorganic fiber blanket and another inorganic fiber decorative fabric, and the fastening device is used for fastening the shutter surface by the clamp plates. The inorganic fiber fire resisting shutter has the advantages that by the aid of the structure, a steel wire mesh arranged in the middle of the shutter surface is omitted and prevented from cutting the inorganic fiber blanket, breakage, corrugation and projection of the shutter surface are avoided, the shutter surface is kept smooth, fastened by the clamp plates through the fastening device and reliably, closely and smoothly compressed together, and the fire resisting shutter is ensured to vertically and smoothly run.
