High-strength compression-resistant prefabricated wallboard

The utility model provides a high-strength compression-resistant prefabricated wallboard, and belongs to the field of prefabricated wallboards. The problems that an existing prefabricated wallboard is poor in strength and compression resistance are solved. The high-strength compression-resistant prefabricated wallboard comprises a wallboard body, and the wallboard body comprises an outer wallboard, an inner wallboard fixed to a wall, a heat insulation layer and a sound insulation layer, wherein the heat insulation layer and the sound insulation layer are located between the outer wallboard and the inner wallboard and used for heat insulation and sound insulation respectively. Splicing structures which are convenient to splice and fix and form concave-convex matching are arranged on the outer peripheries of the outer wall plate and the inner wall plate. The composite board has the advantages of being high in strength, good in compression resistance and good in heat insulation and sound insulation effects. 本实用新
