Abstract
A method of reinforcing structures by means of tensioned steel cables is disclosed. A hollow conduit or duct is positioned in the structure and secured therein and made a part thereof by pouring concrete in a form surrounding the conduit. A specified number of steel strands, wires or cables are inserted and pushed through the conduit one-by-one by a mechanical strand pusher. A nose guide is positioned on the end of each of the strands if required to enable them to pass easily through the conduit. When the required amount of strands are positioned in the conduit and the concrete has set to a predetermined strength, the strands are stressed thereby putting the structure under compression.

A method of inserting reinforcing strands into a conduit extending through a structure to be stressed and then placing the strands under tension in the conduit, comprising
- selectively pushing a plurality of separate strands one-by-one through the conduit forming a group of strands of variable number therein, whereby the number of strands pushed through the conduit may be varied from job to job depending on the amount of reinforcing material required to adequately stress the structure,
- tensioning the group of strands, and
- anchoring the group of strands to the structure in order to maintain the group of strands under tension.
A method of inserting reinforcing strands into a conduit extending through a structure to be stressed and then placing the strands under tension in the conduit, comprising
- selectively pushing a plurality of separate strands simultaneously through the conduit forming a group of strands of variable number therein, whereby the number of strands pushed through the conduit may be varied from job to job depending on the amount of reinforcing material required to adequately stress the structure,
- tensioning the plurality of strands, and
- anchoring the group of strands to the structure in order to maintain the plurality of strands under tension.
