<p>The present invention relates to a steel wire inserting apparatus that can smoothly insert a steel wire by adjusting a friction force between upper and lower support rollers according to the thickness of the steel wire and rotating the steel wire with a proper rotation force when the steel wire is inserted to apply tension to a concrete member. The steel wire inserting apparatus includes a plurality of unit steel wire moving members for moving the steel wires to simultaneously insert steel wires. The unit steel wire moving member includes a plurality of lower gear rotated by a driving unit; a plurality of upper gears each interworking with the lower gear and thus rotated by the lower gear; a plurality of lower support rollers engaged to the side of each lower gear and rotated with the lower gear while supporting a lower portion of the steel wire; a plurality of upper support rollers engaged to the side of each upper gear and rotated with the upper gear while supporting an upper portion of the steel wire; a pair of link members for hingedly connecting the sides of the lower and upper gears and the sides of the lower and upper support rollers to adjust an inclination of the steel wire to an insertion direction; and an adjusting member for adjusting an inclination of the link member.</p> |
