Abstract

598,535. Reinforced concrete. DANHOF, K. R. Feb. 8, 1944, No. 2343. [Class 20(iv)] [Also in Group V] Reinforcement 19 to be incorporated under tension in concrete; moulded in a tube 7 passes through a tensioning device 20 comprising two parallel series of bars or rollers 23. One series is supported in a carrier 24 that is displaceable in relation to the other carrier 25 to determine the sinuous path through which the wire is drawn. The device is slidably mounted and is connected to a tension meter 22, the desired drag on the reinforcement being adjusted against the compression of a helical spring 26.
