Abstract

732,469. Reinforced concrete. MANTSCHEFF, A. Dec. 18 1952 [Dec. 19, 1951], No. 32159/52. Class 20 (4). The cluster of steels 12 for a prestressed concrete structure 11 are cut to size before being brought to the building site and clamped at their ends between a sleeve 21 having a frusto-conical internal bore 21a which narrows towards its outer end and a frusto-conical part 20a of a tie-bolt 20, the part 20a broadening towards its inner end. The tie bolt 20 has a shank 18 which is threaded at 19 and after the concrete 11 has set, the steels 12 are tensioned by a hydraulic press engaging the shank 18. An anchor nut 16 and plate 17 hold the steels 12 in tension.
