The invention discloses an inclined hole combined checker brick structure, relates to the technical field of refractory bricks, and is a regular hexagonal prism-shaped checker brick, and the outside of the regular hexagonal prism-shaped checker brick is provided with checker holes; wherein the upper surface and the lower surface of the checker brick are respectively provided with a central circular lattice hole and eighteen outer edge splicing lattice holes, and the central circular lattice hole and the eighteen outer edge splicing lattice holes are vertical circular holes. Compared with a vertical lattice hole lattice brick of the same specification, the inclined hole combined lattice brick structure has the advantages that the heat exchange area can be increased by 5% and the heat exchange is enhanced on the premise that the hole diameter is not changed, and a large amount of heat storage materials can be saved and the construction cost can be reduced while the efficiency of a newly-built hot blast stove is
