Abstract
The utility model provides a railway steel truss girder bridge ballastless track laying structure which is simple in structure, strong in integrity and good in stability and brings convenience to track construction and reduces maintenance workload. The railway steel truss girder bridge ballastless track laying structure comprises a rail plate (10) and bridge longitudinal beams (20). Rubber cushion layers (21) are laid on the tops of the bridge longitudinal beams (20). The rail plate (10) is arranged above the rubber cushion layers (21). Connection bolts (30) which vertically penetrate through the rail plate (10), the rubber cushion layers (21) and the bridge longitudinal beams (20) fixedly connect the rail plate (10) and the rubber cushion layers (21) on the bridge longitudinal beams (20).
Description
Technical field
The utility model relates to railroad bridge, and particularly a kind of Railway Steel Truss Girder Bridges non-fragment orbit is laid structure.
Background technology
Railway Steel Truss Girder Bridges generally adopts in length and breadth beam system, and bridge deck structure is simple, and steel using amount is few than quadrature Special-shaped Plates system, and construction is simple, and cost is lower.Generally speaking, the in length and breadth supporting sleeper of beam system or resin sleeper track structure pattern.Sleeper railway spike buckle press less generally is only applicable to the railway that speed is not higher than 120km/h, and sleeper is apt to rot, mechanical wear and cracking, and structural life-time is shorter.Though the resin sleeper is functional, but cost is higher, is not suitable for extensive the laying and uses.
For satisfying high-speed railway to the smooth-going requirement of height, should study at steel truss girder and lay non-fragment orbit.Non-fragment orbit is a kind of direct fluid concrete or lays precast track plate to replace the sub rail foundation of traditional railway ballast layer.It has, and globality is strong, good stability, sturdy and durable, track deformation is little, and the advantages such as the distortion accumulation is slow, be conducive to high speed traveling and lay gapless track, be fit to high smooth-going, few requirement of keeping in repair, can greatly reduce the maintenance workload, reduce operation intensity and improve operating condition, the time in circuit comprehensive maintenance skylight is shorter, especially is fit to not allow to utilize the operation condition of running interval upper track operation.In addition, the non-fragment orbit line appearance is neat and artistic.Although the cost of non-fragment orbit is large than Ballast track, in the later stage that track puts into effect, because the minimizing that maintenance cost drops into, the superiority of non-fragment orbit just displays, and non-fragment orbit has significant economic benefit in life cycle.
The utility model content
Technical problem to be solved in the utility model provides a kind of Railway Steel Truss Girder Bridges non-fragment orbit and lays structure, and simple in structure, globality is strong, good stability, and also track construction is convenient, reduces the maintenance workload.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Railway Steel Truss Girder Bridges non-fragment orbit of the present utility model is laid structure, comprise track plates and bridge longeron, it is characterized in that: lay rubber spacer on the end face of described bridge longeron, track plates is arranged on the rubber spacer, and the connecting bolt that vertically passes track plates, rubber spacer, bridge longeron is fastenedly connected track plates, rubber spacer on the bridge longeron.
The beneficial effects of the utility model are, direct laid rail guidance tape on the bridge longeron is simple in structure, adopts the elastic buffer bed course as adjusting layer, and globality is strong, good stability, and is sturdy and durable; Track construction is convenient, can significantly improve efficiency of construction, reduces the maintenance workload, reduces operation intensity and improves operating condition, reduces maintenance cost; Line appearance is neat and artistic.

The title of member shown in the figure and corresponding mark: track plates 10, sleeper piece 11, connecting through hole 12, bridge longeron 20, rubber spacer 21, connecting bolt 30.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, Railway Steel Truss Girder Bridges non-fragment orbit of the present utility model is laid structure, comprise track plates 10 and bridge longeron 20, lay rubber spacer 21 on the end face of described bridge longeron 20, track plates 10 is arranged on the rubber spacer 21, and the connecting bolt 30 that vertically passes track plates 10, rubber spacer 21, bridge longeron 20 is fastenedly connected track plates 10, rubber spacer 21 on bridge longeron 20.Namely direct laid rail guidance tape 10 on bridge longeron 20 is simple in structure, adopts rubber spacer 21 as adjusting layer, and globality is strong, good stability, and is sturdy and durable.Track construction is convenient, can significantly improve efficiency of construction, reduces the maintenance workload, reduces operation intensity and improves operating condition, reduce maintenance cost, and line appearance is neat and artistic.
Described rubber spacer 21 adopts Integral rectangular rubber cushion blocks or sectional type rectangular rubber cushion block to lay along track plates 10 total lengths.Described track plates 10 adopts reinforced concrete prefabricated, and its length is determined according to beam length.Consider Train induced load, the transverse temperature power load of plate and the thermal gradient of plate, determine prestressed reinforcement and plain bars.Track plates 10 is shaped with the connecting through hole 12 that vertically passes for connecting bolt 30 in advance.Connecting through hole 12 can adopt following dual mode to arrange usually: with reference to Fig. 2, the quantity of connecting through hole 12 is 4, at the connecting through hole 12 in the outside and track plates 10 transverse side amongs layout near the sleeper piece 11 of track plates 10 longitudinal terminal surfaces; With reference to Fig. 3, the quantity of connecting through hole 12 is 8, arranges one group at the outside and track plates 10 transverse side amongs near the sleeper piece 11 of track plates 10 longitudinal terminal surfaces, and every group comprises 2 spaced apart connecting through holes 12 on track plates 10 length directions.
The above some principle that the utility model Railway Steel Truss Girder Bridges non-fragment orbit is laid structure that just explain through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
