Improvement in long-lasting beam tuning systems, especially for the construction industry (Machine-translation by Google Translate, not legally binding)

摘要

Improvements in the coupling systems of elongate beams; especially for the construction industry on the basis of two semi-sleepers each composed of a top profile of a lower profile of a parallel beam and close to said upper profile and finally of a connecting strip of said profiles and of said beams characterized by the fact that comprises an upper clamping member for the stable coupling of said upper profiles with said beam and a lower member for coupling said lower profiles; each of said organs carrying a wedge element that allows moving a mobile element respectively for the effective coupling and high adhesion of said semi-sleepers.
