Description
Technical field
This utility model relates to bridge fixing device technical field, is specifically related to a kind of bridge pier bracing means.
Background technology
From the point of view of common building field, two across with two in above bridge in addition to the abutment that two ends are connected with embankment
Remaining medial support structures is referred to as bridge pier.Bridge pier is divided into solid pier, column pier and framed bent pier etc. simultaneously.Can by flat shape
It is divided into rectangle pier, most advanced and sophisticated shape pier, circular pier etc..The material of building bridge pier can use timber, building stones, concrete, armored concrete, steel
Material etc..
Specifically, bridge pier is mainly made up of top cap, pier shaft.Abutment is mainly made up of top cap, abutment body.The effect of top cap is
The power concentrated relatively greatly that spanning bearing is transmitted, disperses and passes to pier shaft and abutment body well-balancedly.Therefore top cap should use intensity
Higher material building, general with being not less than 200 grades of reinforced concrete buildings, and thickness is not less than 40 centimetres.Additionally, top cap is also
Must there is bigger planar dimension, set a roof beam in place for construction and the work surface of maintenance offer necessity.Pier shaft and abutment body be supporting bridge across
Agent structure, be subjected to the whole load that bridge span structure transmits, but also directly bear soil pressure, water flow impact pressure, ice
The multiple load such as pressure, ship impact force, so pier shaft and abutment body all have enough intensity, rigidity and stability.
In recent years, a collection of urban viaduct and viaduct, in order to alleviate traffic pressure, have been built in most domestic city.Solely
Stub Continuous Bridge is little with its occupation of land, the advantage such as penetrating good, good looking appearance of vision is widely used in building of Urban Bridge under bridge
In if.But owing to Single column pier bridge uses single-point support at direction across bridge, lateral confinement ability is poor, at accidental loads such as earthquakes
Under, the lateral shift that girder is bigger may be caused, make support seat occur laterally to come to nothing problem, even cause the beam accident that falls.At present
The beam accident that falls that domestic existing a number of bridge causes due to accidental load, causes great economic loss.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of reasonable in design, structure letter
Single bridge pier bracing means.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: this one bridge pier bracing means, it
Comprise right-angle type fixed support, support spud pile, connecting rod is fixed at the first semi arch support bar, the second semi arch support bar, center,
Fixed expansion bolt；The lower end of described bridge pier is provided with right-angle type fixed support, and right-angle type fixed support is by fixing
Expansion bolt is connected fixing with bridge pier；The lower end of the described horizontal right-angle side of right-angle type fixed support is by supporting spud pile
Connect and have the first semi arch support bar；The outside of described right-angle type fixed support longitudinal direction right-angle side connects by supporting spud pile
The second semi arch support bar, described the first semi arch support bar, the centre of the second semi arch support bar is had to be fixed by center
Connecting rod is interspersed to link together.
In above-mentioned a kind of bridge pier bracing means, described the first semi arch support bar, the second semi arch support
Bar is spaced to be interspersed.
In above-mentioned a kind of bridge pier bracing means, described right-angle type fixed support is fixing of equilateral right angle
Frame.
Compared with prior art, the beneficial effects of the utility model are: its simple in construction, novel in design, use and mutually hand over
Mistake is arranged on semi arch bracing frame as supporting bridge reinforcement, it is possible to well absorb the power that bridge pier produces because of vibrations,
The damage of less bridge pier.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is this utility model semi arch support bar connection diagram.
Wherein: right-angle type fixed support 1, support spud pile the 2, first semi arch support bar the 3, second semi arch support bar 4,
Connecting rod 5, fixed expansion bolt 6 are fixed in center.
Detailed description of the invention:
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As shown in Figure 1 and Figure 2, this detailed description of the invention adopts the following technical scheme that it comprises right-angle type fixed support 1, props up
Connecting rod 5, fixed expansion bolt 6 are fixed in support spud pile the 2, first semi arch support bar the 3, second semi arch support bar 4, center；Institute
The lower end of the bridge pier stated is provided with right-angle type fixed support 1, and right-angle type fixed support 1 is by fixed expansion bolt 6 and bridge
Beam bridge pier connects fixing；The lower end of the described horizontal right-angle side of right-angle type fixed support 1 has first by supporting spud pile 2 connection
Semi arch support bar 3；The outside of the longitudinal right-angle side of described right-angle type fixed support 1 has second by supporting spud pile 2 connection
Semi arch support bar 4, connecting rod is fixed by center in the centre of first described semi arch support bar the 3, second semi arch support bar 4
5 intert link together.
In above-mentioned a kind of bridge pier bracing means, first described semi arch support bar the 3, second semi arch supports
Bar 4 is spaced to be interspersed.
In above-mentioned a kind of bridge pier bracing means, described right-angle type fixed support 1 is fixing of equilateral right angle
Frame.
The operation principle of this detailed description of the invention is: when bridge pier sidewall is by downward borehole pressure, right-angle type is solid
The downforce being subject to is passed to the first semi arch support bar 3 by fixed rack 1, and the first semi arch support bar 3 uses semicircular structure,
Can the support pressure that firmly right-angle type fixed support 1 receives, and give the second semi arch support bar 4 by the pressure transmission that receives, will
Pressure vertically downward is converted into horizontal direction power, reduces the damage of bridge pier.
Although this utility model being described in detail with reference to previous embodiment, those skilled in the art is come
Saying, the technical scheme described in foregoing embodiments still can be modified by it, or enters wherein portion of techniques feature
Row equivalent, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all should
Within being included in protection domain of the present utility model.
