<p>Connecting piece (1) of try-type wire cable channeling sections (B) including a rear section (3) with a W-shaped cross section comprising two longitudinal grooves (30) with a C-shaped longitudinal section, where the wire bars (Vt1, Vt2) of the relevant adjacent cable channelling sections (B, B) are fitted; a central portion (31) that connects the respective longitudinal grooves; and corresponding flanges (32) extending from the outer edges of the longitudinal grooves (30) that are tangentially overlapped at the peripheral area of such wire crossbars of the relevant cable channelling section. Such connecting piece (1) which generally has the shape of a U, has a central branch (10) that practically covers the whole length of the respective central branch (Vt1) of the cross wire bars, and side branches (11) that form an angle with the central branch (10) which is equal to, or greater than the angle formed by the side branches (Vt2) and the central branch (Vt1) of the cross wire bars, and each one of the side branches (11), fully or partially covers the respective side branch (Vt2) of the cross wire bars; furthermore, the length of the flanges (32) corresponding to the side branches (11) is equal to or smaller than the cross distance between the adjacent longitudinal wire bars (VI1 ,VI2), and such flanges comprise a lower bevel edge (320) inclined downwards, to house and retain such longitudinal wire bars (VI1, VI2). The length of the side branches (11) of the connecting piece (1) is chosen so that when the said connecting piece is fitted in the side branches of the relevant crossbar (Vt2), their free end is located below and distant from the end of the longitudinal wire bar (VI1) located immediately above, so that they are not in contact; and at least a window-shaped notch (310) is foreseen at the central area (31) of the side branches (11), whose length (A) has been selected so that the ends of the intermediate longitudinal wire bars (VI2) of the relevant adjacent channelling sections (B, B) do not touch the side branch (11); and a series of respective notches (311) have been foreseen at the central area (31) of the central branch (10) of the connecting piece (1) so that the ends of the longitudinal wire bars (VI1) that form the bottom wall of two adjacent cable channelling sections (B, B) may pass through them without contact.</p> |
