Steering gear of cable member

Abstract

The invention discloses a steering gear of a cable member. The steering gear comprises an ear plate, a bent cylinder integrated with the ear plate, a connecting rod ear plate buckled at one end of the ear plate, a hot-cast infill and a branch pipe group that are fixed in the bent cylinder, stranded wires penetrating the branch pipe group, a damping cushion block fixed at the outlet of the bent cylinder, waterproof covers fastened at the two ends of the bent cylinder, stayed cable Haver pipe sleeve heads buckled on the waterproof covers, stayed cable Haver pipes connected with the stayed cable Haver pipe sleeve heads, cable bands arranged on the inner sides of the waterproof covers and used for fixing the stranded wires, fastening bolts penetrating the waterproof covers and being in threaded connection with the bent cylinder, and water stop rings fixed between the outer side of the circumference at the outlet of the bent cylinder and the waterproof covers. The steering gear has the characteristics of being simple in structure, convenient to replace, excellent in force bearing performance, high in structural reliability, strength and elastic modulus and good in ductility and durability.

Description

technical field [0001] The invention relates to the technical field of a construction device, in particular to a diverter for a cable component. Background technique [0002] In bridge engineering, the cable member bearing the tension needs to pass the steering structure (called the diverter or clamp) to bear the radial component force along the bending section of the cable member in the bending section, so as to realize the force balance state of the isolation body in the bending section of the cable member, Such as figure 1 As shown, and for example: in a suspension bridge, it is necessary to bear the vertical force transmitted by the suspension cable through the clamp installed on the main cable (cable member), such as figure 2 As shown; in straight and arched string beam bridges, it is necessary to bear the vertical force generated by the bending of the cable members through the diverter installed on the support rod (bending member), as shown in Figure 3-5 shown. ...

AI Technical Summary

Problems solved by technology

According to actual needs, the cable design of the trident string girder bridge adopts parallel steel strand cables (such as Figure 10 As shown, the "parallel steel strand cable" is an existing product at home and abroad, which is not the content of this patent application) and a single steel strand can be replaced within the service life of the bridge. The steering structure of the cable must first be positioned and installed After installing the cables, these characteristics obviously do not meet the applicable conditions of the main cable clamp of the suspension bridge, so it is necessary to design a new steering structure according to the characteristics of the trident string beam bridge
