Load bearing concrete perforated self-insulation building block

The utility model discloses a load bearing concrete perforated self-insulation building block. The load bearing concrete perforated self-insulation building block comprises a rear building block body, an insulation layer and a front building block body which are parallel to each other; a plurality of grooves are formed in the insulation layer; the width of an opening of each groove is less than that of a groove body of each groove; a plurality of holes, which pass through the insulation layer and vertical to the outer side surface of the rear building block body and the outer side surface of the front building block body, are formed in the grooves; connecting parts of which two ends are respectively embedded into the front building block body and the rear building block body are arranged in the holes; the front building block body is thicker than the rear building block body; a plurality of rows of lightening holes are formed in the front building block body. The load bearing concrete perforated self-insulation building block further comprises a plurality of supporting blocks. According to the load bearing concrete perforated self-insulation building block, the insulation layer is high in insulation and adhering performances; a built wall body has the advantages of being good in heat insulation and preserving effects, high in bearing strength and long in service life; the building construction can be simplified, thus the construction cycle can be greatly reduced, the thickness of the wall body can be reduced, and the phenomenon of heat bridge between joints of the building block can be removed well.
