Abstract
The invention relates to an anti-overturning bridge pier supporting mechanism, in order to solves the problem that a single-column pier bridge easily causes disconnection of a supporting seat and even capsizing cases as adopting a single-point supporting beam in the prior art. The supporting mechanism comprises a pier column, carbon fiber cloth, a steel hoop component and two supporting seats, the steel hoop component comprises two horizontal support plates, two semicircular cylinders and four connectors, the two semicircular cylinders form a circular cylinder through the four connectors, one supporting seat is arranged on the upper surface of each horizontal support plate, the two horizontal support plates are arranged on the upper surface of the circular barrel horizontally and linearly, the carbon fiber cloth is wound at the top end of the pier column, and the circular cylinder is sleeved on the carbon fiber cloth on the outer side of the pier column. The anti-overturning bridge pier supporting mechanism is used in the field of bridge reinforcing.
Description
Technical field
The present invention relates to a kind of bridge overturning or slip resistance analysis bridge pier supporting device.
Background technology
In recent years, the only bridge type generally built as urban interchange, viaduct of stub continuous girder bridge and since its moulding succinct smooth, building height is little, intervisibility is good under the bridge, the adaptation occasion is many, easy construction and construction costs are lower etc., and advantage has obtained great development.But because solely the stub bridge adopts single supporting seat supporting at direction across bridge, under the uneven loading action of track, whole laterally unstability may take place, a lot of capsizing cases have taken place in recent years, cause great economic loss and abominable social influence.The accident investigation conclusion mostly is overload of vehicle, transfinite due to.The toppling to collapse of bridge construction taken place under the extreme event effect, and be disproportionate with the initial damage scale of structure itself.The continuous girder bridge of only stub single point supporting, overturning or slip resistance analysis moment is not enough to resist the overturning moment that produces under the effect of bridge extreme event, thereby causes supporting seat to come to nothing, even capsizing case takes place.This small probability but the serious accident of consequence has been subjected to the extensive concern of engineering design.Existing only stub continuous girder bridge, if adopt single point supporting, factor of safety against overturning is little, under the extreme event effect, supporting seat is very easy to come to nothing, and then causes top beam body to topple.
Summary of the invention
Only stub bridge adopts single point supporting to cause supporting seat to come to nothing easily in the prior art in order to solve in the present invention, even the problem of capsizing case takes place, and then a kind of bridge overturning or slip resistance analysis bridge pier supporting device is provided.
The present invention addresses the above problem the technical scheme that adopts to be: described supporting device comprises that pier stud, described supporting device also comprise carbon cloth, steel hoop assembly and two bearings, and the steel hoop assembly comprises two horizontal supporting plates, two semicircle cylindrical shells and four connectors; Two semicircle cylindrical shells are formed circular cylinder body by four connectors, the upper surface of each horizontal supporting plate respectively is provided with a bearing respectively, two horizontal supporting plates are on the upper surface that yi word pattern is horizontally set on described circular cylinder body, carbon cloth is wrapped in the top of pier stud, and described circular cylinder body is sleeved on the carbon cloth in the pier stud outside.
The invention has the beneficial effects as follows: lay bearing at horizontal supporting plate, improve the stress of bearing in the bridge later stage operation process, the resistance to capsizing of strengthened beam body prevents that girder from toppling simultaneously, steel hoop assembly of the present invention does not need field fabrication, can be in plant produced, the crudy height can satisfy pier stud boring value bolt and steel hoop and make the requirement of construction simultaneously, shorten the engineering time, steel hoop can be made as the case may be, and structure tube list is convenient to processing and fabricating and is installed and used.
