Compound type fireproof bulkhead for penetrating through floor with cable bridge

The utility model relates to a compound type fireproof bulkhead for penetrating through a floor with a cable bridge. The compound type fireproof bulkhead for penetrating through the floor with the cable bridge is characterized in that a gypsum board body and a metal board coating the outer portion of the gypsum board body are included, and the outer surface of the metal board is coated with a fireproof coating layer. The compound type fireproof bulkhead for penetrating through the floor with the cable bridge has the advantages that the fact that the thermal expansion of a fire proof blockage is changed from local stress to overall stress in the fire propagation process is ensured, and good stability is achieved; the surface of the fireproof bulkhead is made of metal, mechanical strength is high, the fireproof bulkhead is not prone to being damaged and deformed, fireproof coatings with different colors can be sprayed on the surface of the metal board according to a construction environment, and the metal board
