Self-transverse-pulling anti-seismic building block

The utility model discloses a self-transverse-pulling anti-seismic building block which comprises a building block body, first clamping parts are arranged on the two sides of the top of the building block body, a first joint part is arranged at the bottom of the building block body, and in the assembling process, the two adjacent first clamping parts of the building block bodies on the two sides are clamped to the first joint part of the building block body in the middle. Therefore, transverse tensioning force is formed among the plurality of building block bodies. Through clamping of the two first clamping parts and the first joint parts, the self-transverse-pulling assembly effect between the multiple building block bodies can be achieved. Therefore, the building blocks do not need to be bonded into a whole through cement mortar, and transverse tensioning between the building blocks does not need to be achieved through steel bars. Obviously, the building block disclosed by the utility model is higher in bui
