METHOD TO ERECT STRESSED REINFORCED CONCRETE STRUCTURES AND DEVICE FOR ITS REALISATION Russian patent published in 2015 - IPC E04G21/12 E04C5/10 

FIELD: construction.

SUBSTANCE: invention is designed for use during manufacturing or erection of prestressed reinforced concrete structures and facilities, where bundles of stressed reinforcement are high-strength reinforcement ropes laid into channels. A device for passing of bundles of reinforcement ropes includes a traction element, an anchor shell for fixation of bundles of reinforcement ropes and a traction device, the second anchor shell and a body. Anchor shells are connected to each other as capable of rotation relative to each other by means of rotation bearings. As bundles of reinforcement ropes are pulled via the sections of the channel shaper of curvilinear shape, reinforcement ropes are not twisted in the bundle. The device is equipped with a protective jacket installed on the anchor shell. The traction element is made in the form of pulling reinforcement ropes fixed in the second anchor shell. The traction device comprises a hydraulic jack of cyclic action, anchor devices with wedge clamps for serial wedging and unwedging of bundles of pulling reinforcement ropes of the traction element.

EFFECT: method improvement.
