Description
Technical field:
What the present invention relates to is railway ballastless track engineering field, and what be specifically related to is bridge beam seam location ballastless track boards designing technique.
Background technology:
The track plate of orbit Design disconnects in beam seam position generally speaking.When bridge span little, the beam-ends shrinkage joint hour, the fastener spacing at beam seam place can satisfy the requirement of design specifications (regulation in the Chinese Railway design specifications " Line for Passenger Transportation non-fragment orbit Railway Design guide ": the rail length of support is smaller or equal to 650mm).But along with the development of bridge technology, the railroad bridge span is increasing, the beam-ends shrinkage joint is also increasing, and, in order to guarantee the application life of bridge, the place is provided with bridge extension joint at the beam seam, and this device and bridge are not the same life-spans, need keep in repair over a period to come and change.Therefore ballastless track bed board can not cover the beam seam, and will be apart from the beam-ends certain distance, on the other hand, the non-fragment orbit demand of technical standard, railway fastener centre distance road bed board end is not less than 250mm, the fastener spacing is not more than 650mm again, and this just requires not superelevation 100mm of two-phase neighboring trace bed board end clear spacing, and it will be littler requiring the width of beam seam simultaneously.This technical barrier has become a bottleneck of restriction bridge technology and non-fragment orbit technical development.
In addition, when the bridge frame (is generally appearing on the elevated structure at station) on the transom pier crossbeam, if crossbeam face and bridge floor laterally and vertical deformation consistent, the track plated construction will directly be cast on the crossbeam.But when crossbeam face and bridge floor are out of shape when inconsistent, fastener can damage because of interior torsion is excessive, has influence on traffic safety, and the track plate just can not directly be built on crossbeam in this case.
Based on above-mentioned special circumstances,, invented this bridge connected track plated construction for solving the situation that the part can't be supported under crossbeam seam or the plate.
Summary of the invention
The objective of the invention is to invent a kind of rail bridge connection rail plate technique that is used to solve crossbeam seam section, width, crossbeam width and structure that the length of track plate is crossed over the beam seam according to actual needs require to determine, the thickness of track plate can be determined according to the requirement of project actual track structure height, requires the track plate is designed to ordinary reinforced concrete plated construction or prestressed reinforced concrete structure (when requiring span big) according to structural calculation and track relevant design then.
In order to realize above purpose, the present invention by the following technical solutions: four laminated rubber bearings are installed so that enough supports to be provided in bridge joint track plate bottom, and laminated rubber bearing should be chosen according to the specific design load and the structural requirement of project.The convex structure is adopted in bridge joint track plate end, and the common rail plate that joins with it is designed to concave structure, both mutual interlocks.In both sides, bridge joint track plate protruding end spacing bearing B is installed, its function is the lateral displacement that prevents bridge joint track plate, keeps the stable of track plate.Spacing bearing B goes up and adopts the higher polytetrafluoroethylene (PTFE) backing plate of rigidity, and its effect is the lateral impact forces that reduces the track plate, but can not cause the excessive lateral displacement of bridge joint track plate.Owing to have relative displacement between bridge and the bridge joint track plate, therefore leave the shrinkage joint at bridge joint track plate end and common rail plate end, and in the bridging board end two side position erection support C, in the mutual cushioning effect that plays when close of track plate.
Present patent application be the railway bridge guidance tape that integrates with, the track plate adopts reinforced concrete structure.Width, crossbeam width and structure that the length of track plate is crossed over the beam seam according to actual needs require to determine, the thickness of track plate can be determined according to the requirement of project actual track structure height, requires the track plate is designed to ordinary reinforced concrete plated construction or prestressed reinforced concrete structure (when requiring span big) according to structural calculation and track relevant design then.
Four laminated rubber bearings (subplate bearer A among Fig. 2) are installed so that enough supports to be provided in bridge joint track plate bottom, and laminated rubber bearing should be chosen according to the specific design load and the structural requirement of project.The convex structure is adopted in bridge joint track plate end, and the common rail plate that joins with it is designed to concave structure, both mutual interlocks.In both sides, bridge joint track plate protruding end spacing bearing B is installed, its function is the lateral displacement that prevents bridge joint track plate, keeps the stable of track plate.Spacing bearing B goes up and adopts the higher polytetrafluoroethylene (PTFE) backing plate of rigidity, and its effect is the lateral impact forces that reduces the track plate, but can not cause the excessive lateral displacement of bridge joint track plate.Owing to have relative displacement between bridge and the bridge joint track plate, therefore leave the shrinkage joint at bridge joint track plate end and common rail plate end, and in the bridging board end two side position erection support C, in the mutual cushioning effect that plays when close of track plate.Exist to support the gap between bridge joint track plate and the bridge floor, influence the function of moving of bridge joint track plate and bottom support bracket A in going into for preventing foreign matter, in the design in the gap filled polystyrene cystosepiment rise.Rail fastening will be directly installed on above the bridge joint track plate, according to the type difference of selecting fastener for use, can adopt the mode of service sleeve or preburied iron base.
