2 sides of checker brick have respectively with adjacent checker brick matched with buckle structure, buckle structure specifically by locate the box on 1 side of checker brick and locate the buckle on 1 relative side in addition and constitute.

The upper parts of 2 side surfaces of the checker brick corresponding to the long edges are respectively provided with more than 2 bulges, and the vertical cross section of each bulge is in a trapezoid shape with a wide upper part and a narrow lower part.

Compared with the prior art, the beneficial effects of the utility model are that:

1) by arranging the special positioning structure, the checker brick has a quick self-positioning function, so that the laying process is simple, accurate and easy to operate;

2) the self-positioning checker bricks can be laid in staggered layers, and the upper layer and the lower layer are mutually matched through the positioning grooves and the positioning columns to form a stable whole body, can resist certain lateral force, can be used as a pedal foundation, is applied to a heat accumulation chamber of a coke oven with a cellular design, and can greatly reduce the construction difficulty;

3) the protruding structure that self-align checker brick side set up can make checker brick and regenerator owner single wall cooperation location, is applicable to regenerator segmentation slip design simultaneously.
