Description
Technical field
This patent is related to a kind of overhead magnetic floating traffic of the single box single chamber of web holes, is applied to magnetic floating traffic field.
Background technology
Existing magnetic levitation track girder mainly uses the orbit form of railway box beam, magnetic-levitation train to be run at the top of box beam.
It can be influenced by external conditions such as ice and snow or hails when train operation, be unable to reach the requirement of round-the-clock operation.
Existing railway circuit increases guard rail when being laid on bridge, to prevent train from going out along rolling bridge, in case train is to side
Deviate and hits bridge or cause major accident under being fallen from bridge.Existing magnetic floating traffic is elevated rail traffic but does not account for
The derailed possibility of magnetic-levitation train, magnetic-levitation train are once overstepped the limit, it will generate very serious consequence.
Patent No. CN103298675A discloses a kind of vacuum tube transportation system, and the pipeline which uses is closed and company
Continue unlimited long pipeline, which can regard the beam structure as endless as, and as shown in figure 16, pipeline is influenced very by TEMPERATURE FORCE
Greatly, due to being evacuated in pipeline, pipeline needs good airtight performance, has to quality and the processing of material very stringent
It is required that being not particularly suited for long range rail transport.
Force structure system is top plate force structure system, the magnetic levitation track box soffit of girder at the top of existing magnetic levitation track box beam
Plate stress form is web by shearing τ1With compression stress otcBoth compression shear state easy tos produce the mistake that " bending effect " causes structure
Surely, influence of the 3 in Curve Segment train operation to silent beam beam body transverse direction is increased, silent beam is made to generate beam body under special circumstances
The harm such as rollover.
The back plate of existing magnetic levitation track box beam and beam bottom plate are apart from short, according to the mechanical characteristic of beam, as shown in figure 13,
Be under pressure F at the top of box beam1, the bottom under tension F of box beam2, the overall tension and pressure of box beam section are mutually put down
Weighing apparatus, i.e.,：
ΣF1=Σ F2
The rigidity EI of box beam section is directly proportional to the cube of depth of section H of beam, and the top of box beam, bottom surface height difference are got over
The big then section rigidity of box beam increases more apparent.It is public by the development of maximum shear strength of concrete under the influence of not considering reinforcing bar
Formula：
Vc=0.7ftbh0
It understands in the case where box beam lateral dimension b is certain, the effective height h of box beam0It is higher, the shearing resistance of box beam
Intensity is then bigger.Under the influence of not considering reinforcing bar, by the torsion section factor formula of Rectangular Concrete：
Wt=β h3
β is related with the ratio of sectional dimension in formula, it is known that in the case where box beam lateral dimension b is certain, with box
Depth of beam h increases, the torsion section factor W of box beamtBigger, i.e. box beam anti-twisting property is stronger.
In view of the above-mentioned problems, in conjunction with the actual conditions of magnetic floating traffic, patentee by analysis, according to existing theoretical and practical
Experience has carried out numerous studies, has finally proposed this patent from track girder Force principle and track beam action is improved.

Specific implementation mode
This patent action principle explanation
It is former to a kind of effect of overhead magnetic floating traffic of the single box single chamber of web holes below in conjunction with attached drawing 13, Figure 14 and Figure 15
Reason is described further.It should be noted here that being intended only as demonstration by attached drawing described embodiment carries out principle explanation, no
It can be understood as a limitation of this patent.
1) silent beam is bottom slab stress structure
This patent provides a kind of overhead magnetic floating traffic of the single box single chamber of web holes, by driving outside existing magnetic floating traffic
System moves into the inside of silent beam, force structure system, that is, top plate force structure system at the top of original box beam is changed to silent
Force structure system, that is, bottom slab stress structural system inside beam, box-shaped girder web in force structure system at the top of original box beam
Stress form is web by shearing τ1With compression stress otcBoth compression shear state, silent beam inside stress system median ventral plate stress form
Be web by shearing τ2With tensile stress sigmatBoth scissor state, bottom slab stress structural system had been drawn to reduce the relatively silent beam of train load
Height, then reduce influence of the 3 in Curve Segment train operation to silent beam beam body transverse direction, silent beam made to be not easy in special feelings
The harm such as beam body rollover are generated under condition.
2) silent beam improves the mechanical property that existing magnetic floats box beam
From stress with functionally for, this patent provides a kind of overhead magnetic floating traffic of the single box single chamber of web holes, change
Existing box beam stress form, becomes bottom slab stress from top plate stress, considerably increases deck-molding, by concrete box type beam section
Rigidity EI it is directly proportional to the cube of depth of section h of box beam, because of h2>>h1, so the silent beam section of this patent is rigid
Section rigidity of the degree much larger than existing magnetic levitation track girder.Under the influence of not considering reinforcing bar, the development of maximum shear strength V of concretec
=0.7ftbh0, it is known that in the case where concrete boxlike beam lateral dimension b is certain, the effective height h of concrete boxlike beam0More
The shearing strength of height, concrete boxlike beam is bigger, because of h2>>h1, so the silent beam effective height of this patent is much larger than existing
The effective height of magnetic levitation track girder, both the silent beam development of maximum shear strength of this patent was anti-much larger than the maximum of existing magnetic levitation track girder
Cut intensity.Under the influence of not considering reinforcing bar, the torsion section factor W of concrete boxlike beamt=β h3, it is known that concrete box shaped
In the case that beam lateral dimension b is certain, the height h of concrete boxlike beam is higher, and the torsion section factor of concrete boxlike beam is got over
Greatly, because of h2>>h1, so the silent beam torsion section factor of this patent is much larger than the torsion section system of existing magnetic levitation track girder
It counts, both the silent beam anti-twisting property of this patent was much larger than the anti-twisting property of existing magnetic levitation track girder.
It is above-mentioned to illustrate a kind of corresponding action principle of the overhead magnetic floating traffic of the single box single chamber of web holes and function.
It should be intended that, this principle is for single line magnetic levitation track girder straightway, double-circuit magnetic levitation track girder straightway, single line magnetic
Levitation track girder curved section and double-circuit magnetic levitation track girder curved section are equally applicable, and the above action principle is in embodiment below
Just repeat no more.
