A means to engage two vertical pipes or tubes of unlike and increasing size that have been co-inserted such as with a roof or floor drain, in a manner that prevents the contained fluid from overspilling when the said pipes become full or when the fluid flows in a direction opposite from normal gravity flow, which is generally considered as flow from the smaller to the larger pipe. The means of engagement closes the void between the inside diameter larger pipe and outside diameter smaller pipe to withstand fluid pressure in a way that accounts for angular misalignment, pipe or tube eccentricity, manufacturing tolerance, as well as tube condition and debris attached to either pipe sidewall. More specifically, a roof drain system for existing roofs or new construction including a flanged outlet pipe for insertion into the roof drain pipe with the flange mounted on top of the roof. A water straining system is mounted on top of the flange. The outlet pipe is sealed to the interior of the drain pipe by a one-piece rubber molding seal that flexes to easily slide into the drain pipe and withstands high backup water pressures from the drain pipe without leaking. The seal has a Shore A durometer in the range of 30 to 95 and has an annular portion engaging the outer surface of the outlet pipe and an integral flange portion extending outwardly and downwardly from the upper end of the annular portion that seals the inner surface of the drain pipe.

The device of claim 6, wherein said bracket is fixed to said beam by bolting. 8. The device of claim 6, comprising a tie passage, formed in said beam, in order to arrange a region where the tie is coupled to said beam proximate to a lower side of the beam. 9. The device of claim 8, comprising a further tie passage, which connects said beam to said pillar, and is formed in said pillar element. 10. The device of claim 9, wherein said tie passage and further tie passage are formed by tubular bodies which are embedded in said beam and in said pillar element. 11. The device of claim 10, comprising tensioning means for tensioning said tie. 12. The device of claim 11, wherein each said tie has an end, which is fixed to said beam, and a further end, which is constituted by a threaded portion, said tensioning means comprising a nut which abuts against said pillar element and is actuatable for tie tensioning. 13. The device of claim 12, comprising a female thread provided in said tie passage formed in said beam, the end of said tie that is fixed to said beam being threaded and engaging said female thread. 14. The device of claim 13, further comprising a pin which interferes with the end of the tie for locking said tie end in said beam; a tubular body, for accommodating said pin, which intersects the tie passage formed in the beam, said tubular body that accommodates said pin being open at one of its axial ends in order to allow insertion of said pin. 15. The device of claim 14, wherein said box-like body and said tubular body embedded in the body of the pillar element are rigidly connected to each other. 16. The device of claim 15, comprising a plate which is embedded in said beam and is connected to a reinforcement frame of the beam, the tubular body embedded in said beam for the passage of said tie being rigidly fixed to said plate. 17. The device of claim 16, wherein said beam has, at its end to be directed toward said pillar element, a lower recess for resting said bracket. 18. The device of claim 17, wherein said recess is formed by said plate which is embedded in the body of said beam and is rigidly connected to the tubular body that forms the passage for said tie and is embedded in said beam. 19. 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, and wherein said ties are embedded in a concrete casting of a slab performed above said beam. 20. The device of claim 19, 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. 21. The device of claim 20, wherein said cavity is formed by a box-like body which is embedded in said pillar element. 22. The device of claim 21, wherein said bracket protrudes from said side of the pillar element and forms a support for the end regions of said beam, said bracket being rigidly fixed to said beam. 23. The device of claim 20, wherein said cavity and said bracket are inclined upward toward said beam. 24. The device of claim 20, wherein said bracket is fixed to said beam by bolting.
