Abstract
The building block has a hollow body with lateral surfaces which bear a decorative finish, a flat upper surface having studs protruding therefrom, and a bottom opening defining seats for accommodating the upwardly protruding studs of an underlying block. A frog is formed in the flat upper surface for permitting the introduction of an adhesive medium between adjacent blocks. The block can be provided with a framework having an upper frame and legs for interposition between adjacent blocks.

Building block, comprising:
- a hollow body having modular dimensions;
- temporary coupling means being provided at an upper region of said body;
- first engagement means being formed underneath said body at a lower region thereof for interacting with a temporary coupling means of a lower building block;
- at least one hollow blind frog being opened at said upper region of said body for receiving anchoring means for securing said block in a building structure;
- and
- a bottom element for closing said at least one hollow blind frog at said lower region of said body, said bottom element connecting lower perimetric edges of said lower region.

Building block, comprising:
- a hollow body having modular dimensions, said body defining lateral perimetric edges extending between an upper and a lower region thereof, upper perimetric edges at said upper region and lower perimetric edges at said lower region;
- temporary coupling means being provided at said upper region of said body;
- first engagement means being formed underneath said body at said lower region thereof for interacting with a temporary coupling means of a lower building block;
- at least one hollow blind frog being opened at said upper region of said body for receiving anchoring means for securing said block in a building structure;
- a bottom element for closing said at least one hollow blind frog at said lower region of said body, said bottom element connecting lower perimetric edges of said lower region;
- a framework for strengthening said block;
- second engagement means for connection to said framework, said second engagement means being provided at at least one of said lateral perimetric edges;
- and
- third engagement means connected to said framework, said third engagement means being provided at at least one of said upper perimetric edges of said upper region, said framework being engaged by said second engagement means at said lateral perimetric edges and by said third engagement means at said upper perimetric edges for connecting mutually adjacent hollow bodies.
