INTERCONNECTION PIN BETWEEN CONCRETE BLOCKS FOR BUILDING RETAINING WALLS AND RELEVANT BLOCK

摘要

An interconnection pin for constraining blocks, for example made of concrete, to one another, superimposed in rows or layers for building retaining walls, where each block exhibits at least one hole (8) intended to receive and lock at least one end portion of said pin (9) and at least one aperture (10) intended to receive at least one portion of pin protruding from the hole of at least one block belonging to an underlying and/or top row. The end portion for fitting and locking the pin into the hole is shaped as a "flute beak" (9'), so as to favour the forced insertion of said pin into said hole.
