METHOD TO PULL STRANDS OF BUNDLED BARS VIA CHANNEL AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC E04C5/10 

FIELD: construction.

SUBSTANCE: method to pull strands or groups of strands of multi-cored bundled bars via a channel (3), in which a pulled strand or a group of strands (2) is pulled from the first to the second end of the channel by means of displacement of a pulled driving element (1), with which the pulled strand or a group of strands is temporarily connected. The pulled driving element is arranged as capable to prevent its penetration inside the already pulled bundle of strands. The pulled driving element is pulled by means of the first hoist (T2), installed at the side of the second end of the channel, and connected with the second hoist (T1), installed at the side of the first end of the channel, and tensioning of the driving element is carried out with the help of a tension force, pulled by the first hoist, and a braking force, pulled by the second hoist. The device for method realisation comprises a tensioned driving element (1), made as capable of pulling by means of displacement from the first to the second end of the channel of the pulled strand or the group of strands (2), temporarily connected with the driving element with the help of connection facilities. The pulled driving element is arranged as capable to prevent its penetration inside the bundle of already pulled strands.

EFFECT: increased efficiency of strands pulling.
