Embodiment Construction

[0043] figure 1A first embodiment of a connection device 1 of structural elements, in particular a first structural element 2 and a second structural element 3 , according to the invention is illustrated. The device 1 comprises a housing 4 defining a cavity 14, preferably of frusto-conical shape, associated with a plate 6 fixed to the first structural element, for example by welding 2. exist figure 1 In the preferred embodiment, the structural element 2 is tubular and has a circular, square or rectangular cross-section. The plate 6 is fixed to the tubular structural element 2 such that the casing 4 extends inside said tubular structural element 2 . Preferably, the hinge portion 6a is also associated with the plate 6 . The side wall 10 of the housing 4 has one or more holes 12, preferably four holes.

[0044] figure 1 The connecting device 1 further comprises a connecting body 5 having an insertion portion 119 preferably having a frusto-conical shape and defining a cavity...

Abstract

A device for connecting the structural elements, in particular elements of ribs used to support and to consolidate an excavation, reticular structures and similar, comprises at least a first housing (4; 44; 403; 411) having a cavity (14; 414; 144) and capable of being associated with a first structural element (2; 20; 200; 121), at least one connection body (5; 56; 511) having at least one insertion portion (119; 58; 591) for insertion in the said cavity (14; 414; 144) of the said first housing (4; 44; 403; 411) and capable of being associated with a second structural element (3; 30; 131), and locking means (11, 12, 13, 15, 17; 60, 61, 62, 63, 47; 621, 623, 653) for locking the said insertion portion (119; 58; 591) of the said connection body (5; 56; 511) inside the said cavity (14; 414; 144). The housing may be arranged in a cup-shaped element and may be linked in a revolving / hinging manner with the connection body.

Description

technical field [0001] The invention relates to a connecting device for connecting structural elements, in particular elements such as ribs and mesh structures. The invention also relates to a rib for supporting and reinforcing a tunnel, said rib comprising connecting means for connecting said structural elements, and to a method for installing a supporting rib in a tunnel. Background technique [0002] In the field of support structures it is known to use structural elements connected to each other to produce the final form of said support structure. These structural elements may have an open section (for example, a C or double T section) or a closed section. In the case of a closed section, the structural element is tubular and may have any form of section, for example circular, square, rectangular or triangular. [0003] For supporting tunnels, such as motorway tunnels or railway tunnels, it is known to use reinforcing arches called "ribs". In particular, ribs generall...
