Description
Technical field
The utility model relates to rail beam, particularly a kind of middle low speed magnetic floating curve track beam.
Background technology
Because in the middle low-speed maglev train running, vehicle needs " embracing beam " operation, rail beam is positioned at vehicle interior, therefore is positioned at the rail beam on the route curve if " the curved beam is directly done " mode of employing is difficult to satisfy the requirement of vehicle gauge.If adopt traditional " the curved beam song is done simply supported beam ", though alleviate above situation to a certain extent, but to greatly compress rail beam casing width.
The magnetic levitation track structure all need be provided with superelevation usually in the route curve location.Be positioned at the track of different curve location, the setting of superelevation also is different.More than two kinds of technology, realize superelevation by track structure self fully, therefore must adjust back rail supported piece according to route curve, be unfavorable for the standardization of back-up block, be unfavorable for being connected of track and beam body.
In the middle low speed magnetic floating track traffic; The position relation of power rail and orbital plane remains unchanged, and camber beam in the conventional art is when realizing the rail level superelevation through adjustment track self fully; The position relation of rail level and beam body section changes; Therefore the position of the relative beam body section of power rail relation also changes, and the position of power rail built-in fitting must be adjusted according to the setting of track superelevation, installs to power rail and brings very big inconvenience.
Because camber beam has torsional effect, this torsional effect can cause the stressed inhomogeneous and bridge pier transverse bending moment of bearing to increase.Traditional " the curved beam song is done simply supported beam " technology must take special engineering measure to avoid above influence.
The utility model content
The utility model technical problem to be solved provide a kind of in low speed magnetic floating curve track beam, rational in infrastructure, track structure and power rail easy for installation, bearing and bridge pier stressed evenly.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The middle low speed magnetic floating curve track beam of the utility model comprises that Liang Tihe is arranged at the bearing at bridge pier top, is characterized in that: said beam body adopts the curved beam song to do, around the deflection of rail level center line; At beam body two ends and the corresponding bottom of bearing reinforced concrete footing is set respectively; Reinforced concrete footing laterally stretches out and constitutes overall structure with the beam body along the beam body; Reinforced concrete footing bottom surface level, its center and beam body base plate are centered close on the bridge pier center line.
The beneficial effect of the utility model is, rational in infrastructure, track structure and power rail are easy for installation, and the beam body is easy for installation, and bearing is installed simple, and bridge pier and bearing are stressed evenly.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the fulcrum schematic cross-section of low speed magnetic floating curve track beam in the utility model;
Fig. 2 is the spaning middle section sketch map of low speed magnetic floating curve track beam in the utility model;
Member shown in the figure, toponym and pairing mark: beam body 11, reinforced concrete footing 12, rail supported piece 13, bearing 20, bridge pier 21.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
See figures.1.and.2, the middle low speed magnetic floating curve track beam of the utility model comprises beam body 11 and the bearing 20 that is arranged at bridge pier 21 tops.Said beam body 11 adopts the curved beam song to do; Require around the deflection of rail level center line according to the track superelevation; The deflection angle of beam body 11 is by linear change when rail beam is positioned on the circuit easement curve, and when rail beam was positioned on the circular curve, the deflection angle of beam body 11 remained definite value.At beam body 11 two ends and bearing 20 corresponding bottoms reinforced concrete footing 12 is set respectively; Reinforced concrete footing 12 laterally stretches out and constitutes overall structures with beam body 11 along beam body 11; Reinforced concrete footing 12 bottom surface levels, its center and beam body 11 base plates are centered close on bridge pier 21 center lines.
Because rail beam beam body 11 is by the requirement deflection of track, the rail beam cross section can be adopted gauge tolerable size, reasonable stress to greatest extent.Because no matter rail beam is positioned at easement curve still is on the circular curve; Rail beam back plane remains parallel with rail level; The track superelevation is realized by beam body 11 basically; Track structure only need carry out accurate adjustment to the error that 11 constructions of beam body, installation bring, and the low speed magnetic floating track traffic is to the high-precision requirement of track structure in very easily realizing; Because the relative position relation of deflection back rest body 11 cross sections and track remains unchanged; And the relative position of power rail and track remains unchanged; Therefore the power rail built-in fitting remains unchanged in the installation site in cross section, and power rail built-in fitting and support member can be consistent with linear beam.Owing to be provided with beam-ends reinforced concrete footing 12, the deflection of rail beam is convenient, and after 11 deflections of beam body, reinforced concrete footing 12 soffits keep level, and bearing 20 is installed simpler.Because rail beam beam body 11 is to the inboard deflection of curve; And reinforced concrete footing 12 what employing was set is that reinforced concrete footing 12 centers and beam body 11 base plate soffit mid points are positioned on bridge pier 21 center lines; Therefore the relative bridge pier of bridge superstructure center of gravity 21 centers can be to the route curve medial movement; In move the moment of torsion that moment of flexure that the back produces can be able to be resisted camber beam self, make the stressed more even of camber beam bearing 20, the moment of torsion twisting action of camber beam is offset the influence of bridge pier greatly.
Some principles of low speed magnetic floating curve track beam in the above the utility model that just explains through diagrams; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
