Swivel bridge equipment

Abstract

The invention provides swivel bridge equipment which comprises a traction cable guiding device, at least two sets of traction cables and a concrete rotary disc used for bearing a swivel bridge. The concrete rotary disc is of a reinforced concrete structure, the embedded sections of the traction cables are pre-buried in the concrete rotary disc, and the wire outlet sections of the traction cables are wound in the circumferential direction of the concrete rotary disc. The traction cable guiding device comprises a force bearing plate, the force bearing plate is arranged at the wire outlet positions of the traction cables and comprises an embedded part and an extending part which are connected with each other; the embedded part is embedded in the concrete rotary disc, and the extending part islocated on the outer surface of the concrete rotary disc and extends in the circumferential direction of the concrete rotary disc. The wire outlet section, located at the wire outlet position, of each traction cable abuts against the surface of the side, away from the axis of the concrete rotary disc, of the force bearing plate. The swivel bridge equipment can provide support for the traction cables in the radial direction of the concrete rotary disc, the pressure intensity generated by the traction cables on concrete in the bridge swivel construction process is reduced, and concrete crushingand traction cable damage are prevented.

Description

technical field [0001] The invention belongs to the field of bridge construction, in particular to a swivel bridge equipment. Background technique [0002] Bridge swivel construction refers to a construction method in which the bridge structure is formed at a non-design axis position and then put in place by swivel. In recent years, with the rapid development of my country's transportation, the construction of overpass bridges is increasing day by day. Bridge swivel construction can minimize the impact on the existing traffic under the bridge. Therefore, bridge swivel construction has been more and more widely used. . [0003] In the construction of bridge rotation, it is considered to install turntable equipment on the bottom of the pier or the beam bottom of the beam structure. Two sets of traction cables are fixed on the concrete turntable of the turntable equipment. To layout. During the construction of the bridge's rotating body, the rotating torque is provided by syn...

AI Technical Summary

Problems solved by technology

When the traction cable is stretched, the traction cable will exert radial pressure on the concrete along the concrete turntable, especially during the implementation of the large-span or large-span bridge rotation, the exit position and location of the traction cable protruding from the concrete The nearby surface concrete is easily partially crushed by the traction cable, which will cause damage to the traction cable, making it impossible to continue the construction of the bridge rotation
