Assembly type heat-preservation fireproof roof panel

The utility model provides an assembly type heat preservation fireproof roof panel which comprises a steel beam of an I-shaped structure, a steel keel is seamlessly welded to the outer surface of theupper end of the steel beam, a steel bar body is bound in the steel keel, concrete is poured in the steel bar body, and a polyphenyl heat preservation layer is connected to the outer surface of the upper end of the steel keel in an embedded mode. Fine aggregate concrete is poured and sealed on the outer surface of the upper end of the polyphenyl heat preservation layer, the steel keel is composedof four pieces of channel steel, two pieces of channel steel are placed in parallel at equal intervals, and the two sides of each piece of channel steel are each vertically and seamlessly welded withan independent piece of channel steel. The assembly rate of the fabricated building is improved, the construction period is shortened, the cost is saved, and the application of the fabricated buildingis promoted; the heat prese
