Self-thermal-insulation concrete block

The utility model provides a self-thermal-insulation concrete block and belongs to the technical field of designing and manufacturing of concrete blocks. The self-thermal-insulation concrete block adopts the structure that two upper cavities are formed in the upper part of the concrete block body; two lower cavities are formed in the lower part of the concrete block body; a middle cavity is formed in the center of the concrete block body; two cavities with openings are formed in two sides of the middle cavity; all the cavities are filled with foam fillers. The concrete block is made of concrete, and is attractive in style; the upper cavities, the middle cavity and the lower cavities form four I-shaped structures; the concrete block is simple in structure and reasonable in design; as all the cavities are filled with the foam fillers, the concrete block has a self-thermal-insulation function when used for building high-rise buildings; the thermal-insulation effect of the concrete block is obvious; rainwater can
