Z-shaped concrete hollow block with functions of thermal and sound insulation and shock resistance

The utility model relates to a Z-shaped concrete hollow block with functions of thermal and sound insulation and shock resistance, which belongs to wall body material. The concrete hollow block is characterized in that an upper horizontal rib and a lower horizontal rib are arranged in the block body, left and right top surfaces as well as the upper and the lower horizontal ribs of the block body are correspondingly made into a whole, external surfaces of the left and the right top surfaces of the block body are all made into convex surfaces, a staggered surface in the middle of the block body is a plane surface with strip bulges, a rectangular upper hollow layer is formed on the upper side in the block body, a rectangular lower hollow layer is formed on the lower side in the block body, a Z-shaped thermal insulation layer arranged in the middle of the block body and the block body can form a whole, the thermal insulation layer and the upper hollow layer are separated by the upper horizontal rib, and the therm
