摘要

Hollow block for the construction, especially for the lifting of walls and walls of load, which is essentially characterized by being constituted by a single-parallelepiped body that has, on one of its major faces, a longitudinal projection, while on the opposite figure a incoming in correspondence with that one, while in the smaller walls there is, in one of them, a set of external rib and race, while in the opposite they have the same elements but in a diagonally opposite position, all this to allow a tongue and groove both in the superposition as in the juxtaposition of several of the aforementioned blocks, in all of which they also highlight a lower and upper notches made in the walls where the pairs of nerves and races exist, as well as in a middle partition that divides the inside of the piece in two equal chambers, whose recesses are thus located on both horizontal sides of the piece and are of ontorno practically in semi-circle.
