High-strength steam pressurized concrete block

The utility model discloses a high-strength steam pressurized concrete building block which comprises a bottom building block, a limiting groove and a limiting block, an upper building block is arranged above the bottom building block, the limiting groove is formed in the upper surfaces of the bottom building block and the upper building block, the limiting block is arranged at the bottom of the upper building block, and a convex strip is arranged in the limiting groove. Steel bar grooves are formed in the middles of the upper surfaces of the bottom-layer building block and the upper-layer building block. The limiting block at the bottom of the upper-layer building block of the high-strength steam pressurized concrete building block can be clamped into the limiting groove in the top of thebottom-layer building block, and the limiting groove can limit the position of the upper-layer building block, so that the outer wall of the upper-layer building block and the outer wall of the bottom-layer building block ar
