Abstract
Provided is a heat insulating fireproofing brick of a porous staggered structure. The fireproofing brick is of a cuboid structure, a safe working face is arranged in the middle of the cuboid structure, one side of the safe working face is a solid part, the other side of the safe working face is a structural part, the structural part comprises two or more heat insulating holes in a through state or incomplete through state, and the heat insulating holes are filled with heat insulating materials or not filled with heat insulating materials. The heat insulating fireproofing brick of the porous staggered structure is light in weight, has good heat insulation performance, and can reduce the surface temperature by 30-260 DEG C. As the multiple holes are formed in the non-working face of the cold end in parallel or in a staggered mode, heat is transmitted slowly, thermal stress is dispersed, the high-temperature mechanical performance is stable, the requirements for high temperature working conditions are met, the energy conservation effect is remarkable, and market prospects are wide.
