Device for connecting prefabricated beams to pillars or similar load-bearing structural elements

A device for connecting a beam to load-bearing structural pillar elements, for constructing buildings, particularly multi-story buildings, by way of prefabricated concrete components, comprising:

• first connection means for connecting two end regions of the beam to the pillar elements;
• and second connection means for connecting two intermediate regions of a longitudinal extension of the beam to the pillar elements, said first connection means being constituted by connection means of the interlocking type, and said second connection means comprising at least two rigid inclined ties, each of which connecting a said intermediate region of the beam to a region of a respective pillar element which lies at a higher level than the region where the tie is coupled to the beam, wherein said first connecting means comprise:
• a cavity which is formed, for each end region of the beam, in the body of the respective said pillar element, said cavity being open on a side of said pillar element that is directed toward said beam;
• and a bracket which protrudes from said side of the pillar element and is fixed to said beam.
