Description
Technical field
The present invention relates to technical field of rail traffic, more particularly to a kind of assembled fragment-free track slab.
Background technology
Rail system is direct vehicle load and the key structure system for keeping vehicle smooth-going to run in rail traffic,
Play the role of forming a connecting link in entire wheel rail system, rail system is generally by rail, fastener, sleeper, railway roadbed and lower part branch
Support the compositions such as layer.Rail system is divided into Ballast track and non-fragment orbit two types, the road of Ballast track according to the form of railway roadbed
Bed is built by railway ballast, and the railway roadbed of non-fragment orbit is built by reinforced concrete structure.Non-fragment orbit is compared with Ballast track
Compared with having the apparent advantages such as globality is more preferable, stability is good, Trajectory Sets retentivity is good, maintenance workload is few.
Non-fragment orbit most rises early in Europe and Japan, introduces China later, by nearly development in 20 years, non-fragment orbit exists
It is developed in Chinese Railway process of construction, and innovation and development has gone out a variety of non-fragment orbit types.Non-fragment orbit according to
The manufacture of track plates is divided into two kinds of major class of precast slab type ballastless track and cast-in-place non-fragment orbit.Precast slab type ballastless track generation
The CRTS I, CRTS II, CRTSIII plate-type non-fragment orbits for having China of table, Japanese slab track, German Bo Ge
Slab track etc..Cast-in-place non-fragment orbit representative has the CRTS I of China, CRTS II type double-block type ballastless tracks, Chinese
Support block type ballastless track, German 2000 ballastless track system of radar and the general woods non-fragment orbit of the rising sun etc..
Non-fragment orbit has obtained large-scale application, either state-owned railroads field or city in the world at present
Field of track traffic, and have extensive foreground, but still have some problems to be solved, i.e., its adjustment capability compared with
Difference, can repair ability it is poor, when infrastructure occur it is larger sedimentation, horizontal displacement or arch deformation when, non-fragment orbit can not
Be adjusted, therefore, non-fragment orbit the poor area of geological conditions and deformation can not or area more rambunctious paving
And if developing hindered.In addition, prefabricated platy ballastless track structure, the scale of construction of track plates is larger, in manufacture control, fortune
During defeated, site operation and repair are replaced, there is more problem.In the non-fragment orbit being laid at present, partly without the tiny fragments of stone, coal, etc.
Rail system generates destruction because the deformation of infrastructure is excessive, can not normal use, repair replacing construction it is long, difficulty is big, sternly
The normal operation of rail traffic is affected again.Therefore, ballastless track system needs in terms of replaceable, easy-maintaining, big adjustment capability
Carry out deeper into optimization innovation, it is existing to solve the problems, such as.
Invention content
It is an object of the invention to overcome, the adjustment capability of the existing non-fragment orbit in the presence of the prior art is poor, can repair
Reactivation power is poor, and manufacture, transport, construction, inconvenient maintenance deficiency, provide a kind of assembled non-fragment orbit cell board and without the tiny fragments of stone, coal, etc.
Track plates, have the scale of construction it is small, it is easy manufacture, easily transport, easily replace, it is easy-maintaining the features such as, be applicable to tunnel, roadbed, bridge etc.
Type of foundation under various lines.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical schemes：

The bindiny mechanism of plate, wherein include laterally at least two cell boards being connected with each other along track plates, and along track plates longitudinal direction
Also include at least two cell boards being connected with each other.
The assembled fragment-free track slab of the present invention is assembled by several cell boards, not only in work progress
In, the deformation for the track plates for facilitating transport and lifting, and being assembled into is small, during operation, if under line foundation deformation compared with
Greatly, non-fragment orbit is replaced detachably at the unit harden structure of fritter and maintenance difficulty is greatly reduced, enhance the tune of track plates
Whole ability and can repair ability.Therefore, no matter in state-owned railroads or field of urban rail, the present invention all have wide
Promotion prospect.
Preferably, all cell boards form continuous track harden structure or all cell boards form segmentation
, there is segmentation seam between the track plates of different sections in track harden structure, segmentation seam can provide certain deformation space to track plates, subtract
Stress concentration inside few track plates.
Preferably, it is additionally provided with track on the cell board, at this point, fastener system is mounted on track, can not also set
Track, fastener system can be directly installed on cell board.
Preferably, detachable connection between the adjacent cell board, facilitates installation, dismounting and repair.
Preferably, the bindiny mechanism includes the installation room being preset on each cell board, each installation
The interface channel that room is communicated with runs through and connects the connector of the two neighboring interface channel, the connector
Both ends are separately fixed on the two neighboring installation room.After the completion of cell board assembly, it may be selected to carry out the installation room
