ABSTRACT:
A method for end to end coupling prefabricated elements of reinforced concrete, for example so as to realize a column or pillar. The elements (A, B) have cavities (5) in their ends and are placed in alignment with their respective ends comprising the cavities the one against the other, the relative angular position of the elements being such that the reinforcement metallic rods (2a) projecting beyond the end of one of the elements are introduced into the cavities of another adjacent element, and reciprocally, and that the end of the rods (2a, 2b) are introduced with clearance in positioning sleeves (6) having an opening (6') usable for welding. Then the metallic rods put end to end are welded together, and the cavities are filled in with concrete or with another appropriate material.
