Positional couplers speed concrete reinforcement

Hy-Ten's new positional couplers are said to speed up site construction times by using reverse cut threads to link together both reinforcement bars by turning the sleeve in one direction. Richard Webster, director at Hy-Ten, said: "We launched our standard range of friction welded couplers just 12 months ago and the concept has been enthusiastically accepted by both engineers and contractors.

The new couplers from Hy-Ten offer long life and durability.

Hy-Ten's new positional couplers are said to speed up site construction times by using reverse cut threads to link together both reinforcement bars by turning the sleeve in one direction

Richard Webster, director at 4896 Hy-Ten, said: "We launched our standard range of friction welded couplers just 12 months ago and the concept has been enthusiastically accepted by both engineers and contractors. The new positional couplers extend the application of this concept into areas where reinforcement bars are immovable."

Friction welding is said by Hy-Ten to be a new concept in construction, but the technology has been used in aerospace and automotive applications, where joints formed by this method are subject to extreme stress and high workload.

Hy-Ten said its machines securely hold the bar while rotating the coupler at high speed so that the mating surfaces plasticise and achieve a low fusing temperature, creating a joint that is far stronger than those derived from conventional welding.

The new HT (P) and HT (EP) couplers in the 16mm and 40mm diameter range have been fully tested and certi ed by CARES, the certi cation authority for reinforcement steel.

But, as Jeff Winke and Guy Woodford report, the construction of COTA was just as demanding as competing in an F1 race itself For COTA construction contractor Austin Bridge & Road, L.P., nothing was more vital to the successful building of the 5.5km F1 track than meeting the strict criteria for its asphalt-paved surface. “The amount of stress this pavement will un

Statistics are said to reveal that an estimated 50% of all accidents happen during the night when it rains but such conditions occur only 10% of the time and when there are usually less vehicles on the road. Indeed, at the 1st Road Marking Symposium hel
