2 FROM BAR TO SITE ONE PROCESS - ONE PRODUCTION WAY - ONE INSTALLATION Certify : A CONNECTION ALWAYS STRONGER THAN THE REBAR Bar break with visible necking during tensile tests Conception Thread coss section > rebar cross section, Thread length > standards for nuts and bolts, Cold upsetting + ISO profile thread with big pitch Final control of dimensions is indépendent from machinery : guaranty of conformity A CONNECTION TOLERANT TO MISTAKES The full efforts are transfered even with defects of the rebar geometry and / or the installation Advantages and tolerated mistakes Complete transfer of the effort even with a 20% unscrewed connection Profile difference, height of the ribs (depending on the rebar trade marks) : no influence on the result Possible loss of material on the thread : no influence on the strength Easy screwing, no danger of pollution of the thread Mechanical tools for control : normalised and calibrated, no way to have measurement trouble Optimization of the external dimensions of the coupler Impossible to connect a continuation bar of a different diameter Impossible to screw the continuation bar on the bias Self centering of the continuation bar inside the coupler Proper fitting is checked by a simple visual inspection No Torque Wrench needed Simple use even in projects with reinforcement congestion Security of the installation, Blind installation of the continuation bar in projects with reinforcement congestion Anyone can at any time check the connections with just one glance and with no tool No special tool, no calibrated tool No risk to damage the cnnection with a too high torque No risk that the torque is achieved but the efforts are not fully transfered A FINANCIALLY EFFICIENT CONNECTION through an industrial process, a manufacturing in large series, a proximity of construction sites, simple solutions for complex cases. Time saving Standardization Time saving Competitive prices even for complex connections Production ratio Industrial manufacturing of the couplers Easy installation on site

4 production Rebar end treatment and Couplers CUTTING : The rebar end is cut with an automatic bandsaw. THREADING : The upset part is then threaded, by cutting for the range C, and by rolling for the range Dyn. All threads are in ISO-profile. Those operations are done with a specific BARTEC Technology machinery.rond à béton des modes COLD UPSETTING : For each diameter, a machinery and specific dies are used to define and control the volume of material to move and ensure the result. Contrôle : A final check on the thread is proceeded with a predefined frequency : With a calibrated ring for the profile and diameter, and with a depth gauge for the length. At this stage the product manufactured in certified workshops is able to ensure the total transmission of effort. No other additional test or check is needed. Couplers The coupler is manufactured industrially under strict quality control. The raw material has mechanical properties that are defined and permanently checked to ensure compliance of the connection to the most severe applications (earthquakes, shocks,...), the traceability of the material and manufacturing is ensured by a code stamped on each coupler. Cold upsetting Threading Tools Manufacturing of couplers Packaging of couplers Production check Independent of the machine Drawing of a workshop production

5 INSTALLATION The rebar is automatically centered by a chamfr at the end of the coupler. Impossible to connect a continuation rebar of a different Ø from that of the first rebar. Tightened with a spanner with no need to check the torque. Proper fitting by a simple visual inspection. Bad : visible thread Good : invisible thread Visual Inspection Four Types of connections using the same coupler. LS LSR Coupler unscrewing : the rebar does not move. Where the continuation bar can be easily rotated LCE Coupler unscrewing, the rebar does not move. Lock nut Release thread Standard thread Release thread Where rotating the continuation bar is difficult (due to weight, access, etc...) D LRD d Lock nut Where the continuation bar doesn t move Connection of two rebars of different diameters Miscellaneous solutions and accessories DDM RSB Standard sets Anchors LER Connection S couplers for welding V couplers for metal plates and 8.8 class bolt COL plastic flange COL metal flange RFI Insert for threading reservation
