Jacking-type arc-shaped steel plate external-prestressing steel rope diverter

Abstract

The invention discloses a jacking-type arc-shaped steel plate external-prestressing steel rope diverter which comprises a supporting system and a reinforcing system. The supporting system is composed of a supporting plate, an arc-shaped steel plate, multiple connecting plates and a cavity sealing plate, the top face of the supporting system is the supporting plate of a rectangular structure, the top face of the supporting plate is jacked on the bottom face of a beam, the arc-shaped steel plate is arranged on the bottom face of the supporting plate, one end of the arc-shaped steel plate is in welded connection with the supporting plate, an internal cavity is formed between the supporting plate and the arc-shaped steel plate, the connecting plates are arranged in the internal cavity, the cavity sealing plate is arranged at the other end of the supporting plate, the bottom face of the arc-shaped steel plate receives steering bearing pressure of an external steel rope, the reinforcing system is composed of beam-side clamping plates and reinforcing plates which are symmetrically arranged on two sides of the beam, and the beam-side clamping plates and the reinforcing plates are connected on the top face of the supporting plate, and used for connecting the diverter with the beam and improving rigidity of the supporting system. The jacking-type arc-shaped steel plate external-prestressing steel rope diverter is safe, reliable and large in turning radius, the steel rope and the diverter are maintained to be in tangential attachment, and convenience is brought to mounting.

Description

technical field [0001] The invention belongs to the field of structural engineering, and more specifically relates to a jack-up type curved steel plate external prestressed steel cable diverter, which is mainly used to realize external prestressing when the existing structure is reinforced by external prestressing. Steering of stress cables. Background technique [0002] Most of the more than 600,000 bridges in my country have a low design load level. Many bridges have diseases and cannot meet the actual vehicle traffic requirements. They are in overload and "sick" operation. These bridges need to be reinforced and reconstructed. and so on to increase its carrying capacity. The reinforcement methods of old bridges mainly include active and passive reinforcement methods. The active reinforcement method is relatively complex in technology, but it has a good reinforcement effect and can be artificially intervened in the structural force, so it is gradually widely used. Among t...

Problems solved by technology

Furthermore, the strong upward (or downward) force generated by the steering of the cable requires the support plate to have sufficient rigidity, and the stiffness of the device is mainly provided by the combination of the guide plate and the support plate, so the height of the guide plate should not be too small. The larger height of the guide plate reduces its stability and its own bearing capacity
