ES138306U - Perfected unión for tubular construction elements. (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Improved unión for elements of tubular constructions, which is characterized by comprising, for the connection of two tubes perpendicular to each other, two "T" sections of section in half reed, with hole for insertion of the corresponding unión pin with another similar symmetrical piece, in the zone of connection of both sections, foreseeing for the case in which the connection must be triple, that is on the tubes aligned with respect to a third perpendicular to both, forming a cross, a unión similar to the previous one, but based of a double "T", that is, in which on the same horizontal section two vertical sections extend perpendicularly and oppositely, with holes for two pins in their starting areas on it, finally being provided for the angular joints of tubes, in which three elements are perpendicular to each other and one of them is in a plane perpendicular to the other two, a set of two unequal complementary pieces, simi to the previous one, that is formed by a central transverse section and by two others aligned and perpendicular to it, with the difference of finding the piece bent at right angles to the central section, so that the two laterals are at 90º one of another, the central section of the outer part of the angle comprising a portion extending over 270º of the perimeter of the tube to which it engages, while in the complementary internal part the portion of the tube covered by the central section extends only over 90º, the lateral bifurcation on the tube, in a different plane and in a reciprocally perpendicular relation, of the two lateral mouthpieces of the joint, is compensated without any gaps, on whose edges there are also provided perforated fins to allow the weight of so many conventional means of unión with the complementary piece.
