Description
Technical field
The present invention relates to building field, especially a kind of overpass access bridge building for having overturning-preventing and reducing wound.
Background technique
Overpass, i.e. overbridge refer to and rest on a series of narrow armored concrete or bricklaying arch, have high support tower or
Pillar, across the bridge of mountain valley, river, road or other lower barriers.After urban development, congested in traffic, building is intensive,
And street is difficult to widen, and uses this bridge that can improve conevying efficiency with relief of traffic density.In addition, in intercity high speed
Highway or railway, to avoid and All other routes level-crossing, saving land used, a large amount of buildings of overpass, and the position built
Usually densely populated and high traffic place, a large amount of construction will cause a large amount of problems, especially collapsing problem, China
Load-carrying vehicle generally generally overload is serious, the construction of overpass is relatively good, but the access bridge of overpass is because of burden and construction
The problem of sharing, run-of-the-mill are poorer than main bridge, are pressed down the case where splitting and collapsing, such as Hangzhou three so often there is access bridge
Bridge access bridge delivers truck be collapsed accident by overload steel plate, causes Hangzhou San Qiao at least to stop using nearly 1 year, economic loss is tight
Weight.
Summary of the invention
The present invention be in order to invent it is a kind of have overturning-preventing and reduce fall wound overpass access bridge building, he have bottom it is anti-settling and
The ground and supporting beam anti-resonance of Anti-inclining tilt and improve the inner core of stability, and have protection bridge pier and limitation bridge pier
It collapses in the cable handler of safe range.
The present invention is achieved through the following technical solutions: a kind of to have overturning-preventing to build with the overpass access bridge for reducing wound

Vertically several connecting rods, upper junction plate, lower connection is arranged in connection to plate in distance at the top of bent cap between bridge floor beam body bottom
Vertically arranged elastic force stake on the center of plate, elastic force stake are hydraulic elastic axis or the resetting shaft for being sheathed with elastic spring;It is described
Bridge pier and bent cap matching elastic force stake setting position are provided with vertically arranged core bore (17), setting stabiliser bar or stable cable in core bore,
Stabiliser bar or stable cable top are connected on lower connecting plate, and bottom is fixedly connected in the stake of bottom;
Described bent cap bottom or so goes back a left side that is provided with and prevents that collapsing checking bollard (18) and the right side prevents collapsing checking bollard (19), matches and prevents that collapsing cable (20) leads
Draw setting position in abutment and be wholely set left bottom checking bollard (20) and right bottom checking bollard (21), the right side prevents that collapsing the anti-of checking bollard collapses cable and a left side
The connection of bottom checking bollard, the anti-anti- cable that collapses for collapsing checking bollard in a left side are connected with right bottom checking bollard.
As being additionally provided with several pairs of position limiting piles (22) inside the preferred core bore.
As shown in figure 4, being provided with left time on cant beam (23) as the preferred bent cap anti-collapses checking bollard (231) and right time is prevented
Collapse checking bollard (232), left time anti-collapse checking bollard and right time it is anti-collapse the time anti-of traction setting on checking bollard and collapse cable (24), left time anti-to collapse checking bollard
Anti- to collapse cable traction and be fixed on left bottom checking bollard, right time anti-to collapse the anti-of checking bollard and collapses cable traction and be fixed on right bottom checking bollard.
It is additionally provided with as between the preferred bent cap and bridge floor beam body across hole (25), pushes up fixing seat, stabiliser bar or stabilization
Cable, bottom fixing seat are arranged in across hole.
It is equal to right bottom checking bollard to the right anti-length for collapsing checking bollard as the preferably described left anti-length for collapsing checking bollard, the right side is anti-to collapse checking bollard
Length be equal to left bottom checking bollard to the right anti-length for collapsing checking bollard.
As shown in figure 5, stake (27) are stayed in the bottom setting of side cable as being additionally provided with side cable (26) on the preferred bridge pier,
Head end is bundled in the head of bridge pier, and side cable is bundled in stake, and the length of side cable is longer than bridge pier to the length for staying stake.
Implementation principle and mode as shown in Figure 1, the design original bent cap lower end be staggered two it is tight anti-
Cable is collapsed, for balancing the stress of left and right bridge floor beam body and bridge floor, it is ensured that a part can be eliminated, for example left side stress is excessive, then
The anti-cable that collapses in the right will do it the correction of a part, and the stress of bridge floor is allowed to get a promotion;Or excessive situation is accepted in bridge floor
Under, crossed such as the left side stress of bridge floor beam body (4), bridge floor (5) and often have the case where avalanche, have it is anti-collapse cable in the case where, it is anti-to collapse
Cable falls on the side of bridge pier rather than avalanche outward under pullling bridge floor beam body (4), bridge floor (5) directly, fall under bridge
Local-style dwelling houses or road on;
Secondary injury caused by the damage of pontic or bridge pier can also be taken precautions against, the active of actual principle of the invention and automobile damages former
Manage it is relevant, automobile in the 80-90 age in order to focus on constantly increasing oneself weight and protection dynamics safely, as a result, it has been found that
Driver can be protected really under the accident of automobile and car collision, but due to technical staff and data after 20th century of entrance
The accident overwhelming majority of analyst's discovery, automobile is found between automobile and pedestrian, under the refitting protection of automobile, is caused to pedestrian
Mortal injury reduces the automobile refitting energy-absorbing equipment of light protection equipment so producing, these energy-absorbing equipment can increase
" self-destruction " probability, for protecting pedestrian, so starting point of the invention is also, in the case where contingency, what the present invention was built
Bridge pier can stablize inner core in the stress for haling bridge pier always as in Figure 3-5, when stress is to the limit, because
Bridge pier, which is that affirmative is strong plus the stress for stablizing inner core, crosses the individual stress of bridge pier, falls so will appear bridge pier and be individually broken original place
Collapse, along with the anti-presence for collapsing cable, what is control is pullled, can guarantee entirely self-destructed component all original places collapse and
Will not be poured by our common meetings one it is rectangular go, pressing against neighbouring local-style dwelling houses, the mankind or other facilities.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
