EMBEDDED FITTING OF PRESTRESSED POST OF POWER LINE AND METHOD FOR ITS FIXATION IN MOLD Russian patent published in 1994 - IPC

FIELD: production of prestressed posts for power lines. SUBSTANCE: imbedded fitting includes pin for insulator and anchor part in form of rod whose diameter is less than that of pin. Pin has anchor member on one end and its other end is attached at acute angle to pin axis overlapping the end of pin. Method of fixation of embedded fitting in mold when mounting reinforcing frame includes connection of pin to under insulator with anchor rod. Then, anchor rod is installed in reinforcing frame and its free end is passed above preliminarily bent turn of transverse reinforcement of reinforcing frame with rod reinforcing member arranged between turns and subsequent compressing between turns by tensioning longitudinal reinforcement of reinforcing frame. EFFECT: higher efficiency. 2 cl, 3 dwg
