The invention relates to production of a
hollow wall body module and a building utilizing the
hollow wall body module, and aims to provide a hollow
reinforced concrete prefabricated wall body module. The module is T-shaped, L-shaped, cross-shaped or transversely l-shaped; a plurality of through holes which penetrate through the module along the vertical direction are uniformly formed in the module; the hollow
reinforced concrete prefabricated wall body is characterized in that each through hole is a square body of which the edges are parallel to the surface of the module; a groove for accommodating a girth reinforcing
steel bar is formed in the upper end of the module; at the part, positioned in an outer wall, of the groove, the height of the groove wall of the groove is equal to the height of the groove wall on the other side after a
floor slab is placed; at the part, positioned in an inner wall, of the groove, the heights of the groove walls on the two sides of the groove are equal; at the part, positioned in the outer wall without the
floor slab of the building, of the groove, the heights of the groove walls on the two sides of the groove are equal. By using the module, the integrity of the building can be enhanced remarkably, the structural performance of the building can be improved, the construction process of the building can be simplified, and the construction efficiency of the building can be improved; the overall module is light in weight, convenient to
machine, and lower in cost; the scaffolding-free, framework erecting-free and painting-free requirements are met.
