Multi-purpose part

Multi-purpose part wherein it comprises:

• a frusto-conical projection in a lower end INF;
• a frusto-conical housing in an upper end SUP, arranged to match the frusto-conical projection and facilitate the stacking and fitting of a module on top of the other by means of a tight approach and a tongue and groove connection secured by an alignment of both modules in-plant;
• a falling mortar pipe extending from the upper end SUP to the lower end INF of the pillar and having, at the lower end INF, a portion which curves from a downward vertical plane toward a front face of the frusto-conical projection for the introduction of mortar;
• a rising mortar pipe extending from the lower end to the upper end SUP of the pillar and having, at the lower end INF, a portion which is bent from a horizontal plane toward an upward vertical plane so that the mortar introduced rises until a cavity defined by the mortar pipes, the frusto-conical housing and the frusto-conical projection is filled.
