Problems solved by technology

Although the above method reduces the damage of the bridge structure to a certain extent, it has the same problem as method 2, that is, it is generally only applicable to areas with peak ground acceleration (Ag≤0.15g)

Embodiment

[0029] Example: see Figure 1-4 , a bridge girder anti-deviation device, including two sets of beam body fixing components arranged on the left and right sides of the beam body lower surface along the width direction, the beam body fixing component includes an anchoring bottom plate 1′, and the anchoring bottom plate 1′ extends along the beam The width direction of the body is set and anchored on the beam body, and the anchor base plate has a displacement follow-up plate 2' vertically arranged downward along the longitudinal direction of the beam body, and the bottom of the two displacement follow-up plates 2' is horizontal An elastic member is arranged on the ground, and the elastic member uses the support member under the beam body as the installation and support base. In this embodiment, the supporting member is a beam cover.

[0030] In this way, the anchor base plate and the beam body are anchored together, and the offset stress in the left and right directions of the be...

Abstract

The invention discloses a cover beam type bridge deviation prevention device. The cover beam type bridge deviation prevention device is characterized by comprising two beam body fixing assembly sets arranged on left and right sides of the lower surface of a beam body along the width direction, each beam body fixing assembly set comprises an anchor foundation plate which is arranged along the width direction of the beam body and is connected to the beam body in an anchored manner, a displacement tracking plate arranged straight down along the lengthwise direction of the beam body is arranged in the anchor foundation plate, an elastic component is horizontally arranged to the left and right direction between the position under the two displacement tracking plates, and the elastic component is mounted on a bridge pier limit-oriented component anchored in the front side face or the rear side face of the cover beam by taking the cover beam under the beam body as a mounting support base. The invention further discloses a cover beam type bridge deviation prevention method adopting the device. The cover beam type bridge deviation prevention device and cover beam type bridge deviation prevention method have the advantages of simpleness in structure and convenience in construction, horizontal restrain on the beam body of the bridge can be well achieved, restraint stress can be released, and potential safety hazard is lowered.

Description

technical field [0001] The invention relates to the field of highway and bridge engineering, in particular to a cover beam type bridge anti-deviation device. Background technique [0002] At present, most small and medium-sized bridges in service in my country (especially curved continuous box girder bridges) are prone to large lateral deviations of the main girders under the effects of expansion joints stuck, temperature effects, and eccentricity of static and dynamic loads. And the offset gradually accumulates over time. These bridges with deflected beams have seriously threatened the safety of road operations, and it is very necessary to carry out targeted repairs and reinforcements. At the same time, for the research on the phenomenon of bridge deviation, it is necessary not only to study the causes of beam deviation and the method of correcting construction and monitoring process, but also to find a way to fundamentally solve the problem of beam deviation—that is, measu...
