The cladding of columns and column-beam nodes, the so-called "jacketing", is an effective reinforcement technique obtained by ringing the original section with a reinforced concrete layer.
This technique has been applied for some time and is supported by clear regulatory references (Italian Technical Standards and Eurocode 8). With the appropriate attention to detail, a series of benefits are obtained simultaneously for the correction of construction defects typical of the past, such as the increase in stiffness, the increase in resistance to bending and shear, the increase in ductility, helping to
to easily achieve seismic upgrading in the majority of cases of professional practice.
Past experience has shown that the most frequent criticalities found in reinforced concrete buildings are connected to the incorrect closure of the brackets, made by simple overlapping with a 90° bend, and to the absence of brackets in the columns at the intersection with the beams.

The TECHNARIA GTS COUPLER allow for the best possible “jacket” of reinforced concrete structures in the seismic areas; the special GTS joints with mechanical clamping have the peculiarity of being able to achieve the continuity of the brackets in the event of jacketing of beam-column joints and columns and, thanks to the very small dimensions of the sleeve and the special laying tools, allow for the creation of reinforced concrete liners with a thickness contained within 6/7 cm. The choice of a mechanical joint in seismic areas is mandatory in areas of plastic hinge, as the standards do not allow the use of welding in the head and foot of the column in order to avoid breakage of a fragile type.
The brackets mechanically closed with the TECNARIA GTS joints represent the "safety belt" of the reinforced concrete buildings.
