Embodiment Construction

[0022] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] The hanging cable circulation device includes a pay-off reel, a winch, a traction device, and a cable puller, wherein the pulley is arranged on the beam, and the cable puller is arranged at the tower end, and the cable puller and the pulley are connected by a wire rope, and the wire rope passes through two A set of guide wheels is used for steering. When in use, one end of the steel strand on the pay-off reel is connected to one end of the traction groove of the traction device, and the other end of the traction device is connected to the hoist through a wire rope to form a closed rope system. The cable puller is used for tensioning the pre-tensioned steel strand.

[0024] The anchoring system of the cable-stayed cables of the parallel steel strands adopts a sealing cylinder to replace the combination of the support cylinder and the ext...

Abstract

The invention provides an arrangement method for cable-hanging of single parallel steel strand wires. By adopting an enclosed signal steel strand cable-hanging circulating device and utilizing a network intelligent tension system, cable-penetrating speed and tension quality are greatly enhanced. The method comprises following steps: pulling the steel strand wire to the cable-hanging circulating device to a platform outside a tower and linking the steel strand wire with a cable-pulling device at an anchoring end and pulling the steel strand wire into an anchorage device at a tower end, installing clamp pieces and tensioning and pre-tightening; linking the other end of the steel strand wire with the cable-pulling device at the anchoring end of a beam end, pulling the steel strand wire to a beam-end anchorage device; installing clamp pieces and tensioning and pre-tightening; sequentially hanging cables of the whole steel strand wire; pulling the steel strand wire out to certain length outside the anchorage device at the tensioning and anchoring end of by a pulling rope and anchoring; continuing to pulling and fixing the pulling rope at the anchoring end till length of the steel strand wire penetrating out of the outside part of the tensioning and anchoring end of the anchorage device reaches the working length; anchoring the other end of the steel strand wire, dismantling the pulling rope and pulling the other steel strand wire; and pre-tightening and tensioning two steel strand wires.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for arranging hanging cables of a single parallel steel strand. Background technique [0002] Parallel steel strand cables generally use a single hanging cable and a single tensioning construction method. After this, the lock body needs to be adjusted by a single cable in the later stage. The traditional cable adjustment method is to use sensors and jacks to manually adjust the cable , the error range is large, and the work efficiency is low. Contents of the invention [0003] Aiming at the problems of slow progress and poor control of tensioning precision in the traditional cable-hanging construction method, the present invention provides a new type of arrangement method for hanging cables with parallel steel strands. The networked intelligent tensioning system greatly improves the speed of threading and the quality of tensioning. [0004] In ord...
