Self-locking block and complementary pieces for the raising of pillars and free-standing walls

Abstract

The present invention relates to rooms or buildings constructed by raising walls using prefabricated blocks made of Portland cement mortar reinforced with steel fibers, that are stable without requiring a mortar mixture, or any additional internal or external structural support for the construction of the walls.

1 - 8 . (canceled) 
     
     
         9 . A construction block consisting of:
 portland cement;   sand;   water; and   steel fibers   wherein the portland cement, the sand, the water, and the steel fibers are mixed and then pressure molded at room temperature.   
     
     
         10 . The construction block of  claim 9 , wherein the construction block is a block, a semi-block, a lintel beam, a crown beam, or a head beam. 
     
     
         11 . The construction block of  claim 9 , wherein the block comprises:
 a base having a top end, a bottom end, two separate cavities symmetrically placed inside the base, and hollow protrusions extending over the top end of the block, wherein the cavities run from the top end to the bottom end of the base; and each hollow protrusion is connected to one of the cavities;   each cavity includes:   a first segment located near the bottom end of the base having a square shape with a first longitudinal dimension;   a second segment connected to the first segment, the second segment having a square base with a second longitudinal dimension;   the first longitudinal dimension is greater than the second longitudinal dimension; and   a step formed at a point where the first segment connects with the second segment;   wherein the block connects to at least one second block free of without using an external structural support, a plaster, an internal structural support, an adhesive, a mortar mixture, or support beams.
