Abstract

700,497. Prestressed concrete. LAING & SON, Ltd.,J. Oct. 21, 1952 [July 2, 1952], No. 16658/52. Class 20 (4) A positioning - device for pre-stressed reinforcing wires comprises a tube A having transverse slots B for receiving the wires and spaced according to the required spacing of the wires, with a rod C or the like passed between the inner wall of the tube and the wires to hold the wires in the slots. The device is then lowered into the spacing frame D.
