Sintering S-shaped self-insulation building block

The utility model relates to the field of buildings, in particular to a sintered S-shaped self-insulation building block. The sintered S-shaped self-insulation building block comprises a shell, the cross section of the shell is S-shaped, holes A are formed in the upper portion, the middle and the lower portion of the shell, a hole B and a right inserting groove are formed between the upper portionand the middle of the shell, a hole B and a left inserting groove are formed between the lower portion and the middle of the shell, a painting groove is formed in the outer wall of the shell, and theinserting groove is provided with a foam plate. The sintered S-shaped composite self-insulation building block has the beneficial effects that the heat insulation performance is good, the heat insulation requirements of buildings with different body type coefficients can be met, the equivalent heat conduction coefficient of the sintered S-shaped composite self-insulation building block can be less than 0.1 W/(mk), and the
