Shockproof tenon engaged flatly-built connecting brick

The invention discloses a shockproof tenon engaged flatly-built connecting brick, which comprises butting surfaces, a bonding end surface and a side surface, wherein a protruding tenon and a tenon pit are respectively arranged on the two butting surfaces; the shape and the size of the tenon pit correspond to those of the protruding tenon; when the protruding tenon of one brick is inserted into the tenon pit of another brick, four peripheries of the butting surfaces of the two bricks are aligned. After the bricks are flatly built, the bricks are matched to form engaged structures through insertion of the protruding tenons and the tenon pits, single-layer bricks are flatly built and engaged like a floor after splicing, and the upper and lower parts of the flatly-built brick wall are solidified and engaged into a whole through cement mortar by material reducing holes. A house frame type wall built by the shockproof tenon engaged flatly-built connecting bricks is firm in structure and high in impact resistance and can bear shock of a magnitude-7 earthquake. The shock resistance of a house is greatly improved, and compared with the conventional common bricks, the shockproof tenon engaged flatly-built connecting brick has the advantages that the connecting engagement strength can be enhanced by over 60 percent, and the shock resistance of the wall is improved by 1 to 3 times.
