An expansion joint structure of hot stove equipment is to provide a hot air tube metal plate fixed to one side of a cooling unit in order for the other side of the cooling unit to be moved according to the motion of the hot air tube metal plate, thereby preventing the damage to a bellows. An expansion joint structure of hot stove equipment comprises a hot air tube metal plate(320), a bellows(333) and a cooling unit. The hot air tube metal plate surrounds an insulating brick(310) of the hot air tube metal plate. An extra slit(325) is separated from the hot air tube metal plate toward an exterior circumference direction thereof. The bellows expandable in a longitudinal direction is fastened with the both ends of the hot air tube metal plate by fixing rings(331). The cooling unit is installed on the both ends of the hot air tube metal plate to block the extra slit of the hot air tube metal plate.
