Description
Technical field
This patent is related to a kind of cross-saddle single-track traffic consolidation formula two-orbit beam, applied to cross-saddle single-track traffic field.
Background technology
Cross-saddle single-track traffic is that vehicle is straddled on track girder, track girder be both vehicle bearing structure when driving and
Guide frame.As used herein, term " two-orbit beam " refers to that there are two monorail track beams for tool in an independent beam body.Term
" one rail of a beam " refers to that only there are one monorail track beams in an independent beam body, this is traditional track girder.
Conventional track girder uses the form of one rail of a beam more, and track girder is individually erected on bridge pier, left and right adjacent two
Without lateral ties between track girder.A kind of track girder as disclosed in patent No. CN205576650U, individual track girder pass through branch
For seat freely-supported on bridge pier, the overall stiffness of this structure is insufficient so that shaking is easily generated when monorail train is run on it, this
The comfort of the travel speed and traveling of train will be influenced, and the loss of train tire can be increased etc..And this tradition
Track beam structure can also be easy to topple, the problems such as when earthquake may fall beam.
Chinese Patent Application No. CN205688287U discloses a kind of U-rail beam, and two web bottoms are used bottom plate
Connection forms overall structure, and U-rail beam freely-supported is on bridge pier.The concept source of U-rail beam is in railway and subway, in railway
In the U-rail beam used with subway, force structure of the bottom plate as carrying train；And in monorail transit field, web is then
It is the force structure as carrying train.Therefore, although such track girder increases the rigidity between monorail track beam,
But this is not optimal technical solution in monorail transit field.When bottom plate is located at web bottom, the bending resistance of track beam structure
Rigidity when rigidity is located at other positions compared to bottom plate is all small.As shown in figure 37, left web width is b11, it is highly h11, abdomen
Plate centre of form axis O11—O11Apart from web bottom sideline O31—O31Distance is L11, right web width is b21, it is highly h21, abdomen
Plate centre of form axis O11—O11Apart from web bottom sideline O31—O31Distance is L21, baseplate width b31, it is highly h31, sole shape
Mandrel O21—O21Apart from web bottom sideline O31—O31Distance is L31, E is the elasticity modulus of concrete.The then U-rail
Beam is for web bottom sideline O31—O31Bending stiffness EI1For：
It will be clear that when each web of track girder and constant bottom plate sectional dimension, the rigidity of track girder is with bottom plate
The promotion of position and increase, i.e. EI1With L31 2Increase and increase.
In view of the above-mentioned problems, the track girder rigidity with reference to traditional one beam of cross-saddle single-track traffic, one rail form is smaller, anti-
Toppling property is poor, earthquake when the problems such as being prone to fall beam actual conditions, inventor by analysis, according to existing theoretical and practical
Experience from track beam stress mechanics principle, is studied, is developed, finally propose present patent application.
Patent of invention content
This patent the technical problem to be solved is that：It provides one kind to be formed by two webs and a floor combination, bottom plate
The two-orbit beam at certain position between two web bottoms and the top plays the rigidity of increase track girder entirety
Effect, at the same have transverse bottom plate connect two-orbit beam can to avoid when earthquake occurs single track beam be easy to fall asking for beam
Topic substantially increases the shock resistance of guideway beam structure.
Technical solution is used by this patent solves its technical problem：
A kind of cross-saddle single-track traffic consolidates formula two-orbit beam, it is characterised in that：Cross-saddle single-track traffic consolidates formula double track
Road beam is formed by two webs and a floor combination, certain position of bottom plate between two web bottoms and the top
Place, two-orbit beam consolidation is on the bent cap of bridge pier.
A kind of cross-saddle single-track traffic consolidation formula two-orbit beam, it is characterised in that：The web of two-orbit beam for etc.
Height web；Or the web of two-orbit beam is And of Varying Depth web.
A kind of cross-saddle single-track traffic consolidation formula two-orbit beam, it is characterised in that：The linear of two-orbit beam is straight
Line is linear；Or two-orbit beam is linear linear for curve.
