BARTEC Process
—— Process Bartec
Process description
Since 1988, when the first patent describing the process of transforming the end of the rebar by cold forging and threading was filed, LINXION The Original has constantly improved the quality and optimized the production tools for this type of mechanical splices.
The first truly “bar-break” reinforcement connection available on the market.
To obtain and guarantee a mechanical splicethat is stronger than the rebar itself, the quickest and most economical solution is to increase the diameter of the bar end by forging, and then to produce a thread with a stronger cross-section than the bar.
Cold Forging description
Only our cold forging production tools are capable of guaranteeing the right quality and a very economical turnaround time. The performance of our industrial production tools ensures perfect geometry of the end of the reinforcing bar, and perfect control of the volume of steel to be displaced on all diameters and grades of steel worldwide. It’s important to have an upsetting perfectly centered on the bar and correctly proportioned to the thread to be produced.
Threading description
To ensure that our mechanical splices are stronger than the rebar itself, we produce a cylindrical thread on the part, inspired on ISO standards, which guarantees a stronger cross-section than that of the rebar. Our industrial threading tools ensure repeatability and low production costs. Our quality system and thread control procedures guarantee a mechanical splice with high safety coefficients, ensuring a “bar-break” in all conditions.
Mechanical splices
The mechanical assembly of the mechanical splice consists of two threads and a coupler, and for certain connections, mechanical accessories. These are derived from design calculations and validated by experimental tests. The coupler is the essential accessory for connecting two reinforcing bars, and is manufactured using an industrial process that ensures quality and traceability. Each coupler is identified by its material batch.
The transmission of forces from one rebar to another passes exclusively through the coupler, and no longer through the concrete as in a traditional overlap connection. This is why we destroy a coupler every 1,000 products, as it must be considered a safety component.
Depending on your needs, we offer 4 different types of reinforcement connection:
– Standard splice (LS)
– Slight rotation splice (LSR)
– Position splice (LCE)
– Bridging splice (LER)
