Blind-hole socketed brick

The invention discloses a blind-hole socketed brick. The blind-hole socketed brick comprises a brick body, wherein a plurality of cavities are formed in the brick body; each cavity extends from the front end to the rear end of the interior of the brick body; the front end and the rear end of the brick body are respectively designed into outwardly convex male connector and an inwardly concave female connector; the male connector and the female connector are matched in shape and size to form a socketed laying seam structure; a plurality of strip-shaped through grooves are formed in the outer surface of each of the upper wall, the lower wall, the left wall and the right wall at equal intervals; the outer surface of the brick body can be glazed. The blind-hole socketed brick has the benefits that the socketed laying seam structures are adopted during brick laying; during brick laying, as the blind holes are formed in one end, mortar leakage is prevented, the mortar consumption is reduced and the brick laying stability is improved; a sawtoothed filling layer can be formed between the upper-layer brick body and the lower-layer brick body through the strip-shaped through grooves, so that the fastness degree of connection between the brick bodies is improved; the air holes are reserved in one ends of the blind holes to achieve ventilation during roasting so as to prevent cracks; after the outer surface of the blind-hole socketed air brick is glazed, the smoothness degree is high and a decorating role can be played.
