Burning structure of cross-shaped structure

The invention relates to the field of fire-resistant burning equipment components, in particular to a burning structure of a cross-shaped structure. The burning structure comprises two brick bodies which coordinate with each other. The upper portion and the lower portion of the left side of a brick face of each brick body are symmetrically provided with protrusions which are each of a cross-shapedstructure. The upper portion and the lower portion of the right side of the brick face of each brick body are symmetrically provided with cross-shaped grooves which coordinate with the protrusions. The two sides of each brick body are symmetrically provided with reinforcing grooves. When the brick bodies are spliced and installed, the two sides of the brick bodies are reinforced and installed ina manner that a reinforcing block of an n-shaped structure is embedded into the reinforcing grooves, and the brick faces are spliced in a manner that the protrusions are embedded into the grooves in acoordinating manner.
