Section for Structures and Relative Structure

Abstract

A section with a “T” profile comprising a rib and a plate which extends from a first to a second end. The section having, in proximity of at least one of said ends, a coupling element suitable to engage with a further section, and the rib comprising at least one engagement aperture shaped to house said coupling element. Advantageously, the coupling element comprises an attachment base to the rib which projects at least partially from the section with a free end, and a tongue elastically flexible and connected to the attachment base. The tongue is bent towards the attachment base at said free end so as to form an angle of incidence with the attachment base, and is provided with a coupling hole suitable to engage with at least a first tooth of the engagement aperture.

1 . Section in particular for structures, having a main longitudinal extension from a first to a second end,
 the section having, in proximity of at least one of said ends, a coupling element suitable to engage with a further section,   the section comprising a rib and a plate positioned perpendicular to the rib so as to form an overall “T” section,   the rib comprising at least one engagement aperture shaped to house said coupling element, the engagement aperture being positioned between said first and second ends,   wherein   the coupling element comprises an attachment base to the rib which projects at least partially from the section with a free end, and a tongue elastically flexible and connected to the attachment base,   the tongue being obtained through shearing and bending of a portion of the attachment base, so as to form an angle of incidence with the attachment base itself,   the tongue being provided with a coupling hole,   the engagement aperture defining at least a first tooth suitable to engage with the coupling hole of the tongue.   
     
     
         2 . Section according to  claim 1 , wherein the engagement aperture has a first pair of guides positioned on opposite sides to the first tooth, and said coupling element has a first pair of tabs overhanging the attachment base, said first guides co-operating so as to slide with the first tabs to guide the engagement of the coupling element. 
     
     
         3 . Section according to  claim 1 , wherein the engagement aperture defines at least a second tooth, opposite the first tooth in relation to a centreline plane of the engagement aperture orthogonal to the main longitudinal extension, to permit the contemporary restraint of two coupling elements of two separate sections. 
     
     
         4 . Section according to  claim 3 , wherein said centreline plane is also a plane of symmetry for the engagement aperture. 
     
     
         5 . Section according to  claim 3 , wherein the engagement aperture has a second pair of guides positioned on opposite sides to the second tooth, to permit the guided engagement of two coupling elements of two separate sections. 
     
     
         6 . Section according to  claim 1 , wherein the attachment base is attached to the rib by riveting, welding, gluing and/or threaded connection means. 
     
     
         7 . Section according to  claim 1 , wherein the free end of the attachment base has a pair of shoulders which define a limit stop in the insertion of the attachment element inside the engagement aperture, said shoulders abutting against the rib. 
     
     
         8 . Section according to  claim 1 , wherein the free end has a pair of bevelled drafts to facilitate insertion of the attachment element inside the engagement aperture. 
     
     
         9 . Section according to  claim 1 , wherein said rib, on the side opposite the plate, comprises a longitudinal stiffening element. 
     
     
         10 . Structure, in particular to support false ceilings, comprising a plurality of sections according to  claim 1 , wherein said sections are mechanically connected to each other so that the attachment element of a first section engages in the engagement aperture of a second section.
