Steel plate wall heat preservation fireproof structure

The steel plate wall is provided with the fireproof layer and the heat preservation layer, the steel plate wall has the fireproof and heat preservation effects at the same time, the heat preservation layer is provided with the connecting piece and the abutting piece, the connecting piece penetrates through the heat preservation layer, the abutting piece is arranged at the end, penetrating out of the heat preservation layer, of the connecting piece, and the abutting piece abuts against the heat preservation layer, so that the heat preservation layer and the steel plate wall are tightly fixed. By means of the arrangement, the wall body formed by combining the steel plate wall and the heat preservation layer is compact, the defense and protection capacity of the wall body is improved, the heat preservation wall is applied to practice, the probability of displacement, hollowing and falling of the heat preservation layer is greatly reduced, and good practicability is achieved. 本实用新型使钢板墙设置防火层和保温层，使得钢板墙同时具有防火和保温的效果，
