Description
Technical field
The utility model relates to railroad track technical fields, and in particular to a kind of Novel sleeper of encased steel plate.
Background technique
Sleeper is placed under rail, is supporting rail and rail load is spread the important component in railway roadbed, be iron
One of rail road chief component.Sleeper should play the role of fixed location of rail and keep gauge, should also have certain
Elasticity and insulating properties, and guarantee firm reliable and enough service life.Sleeper is had by the classification of its material:Sleeper, concrete crosstie,
Steel sleeper etc..Sleeper is a kind of sleeper that railway uses earliest, elasticity and good insulating, have many advantages, such as it is light-weight, easy to process,
But it is easy by mechanical failure, not fire resisting, short intolerant to burn into service life, therefore using less in modern railways.Steel sleeper was once
It is widely used on Germany and Switzerland's railway, bearing load simple with production process is big, firmly hold gauge,
The advantages that can provide biggish vertically and horizontally resistance, but its steel using amount is big, cost of manufacture is high, and be easy to corrode, noise it is big, so making
With range by biggish limitation.Concrete crosstie long service life, track stability are good, are able to satisfy high speed, large conveying quantity requirement, because
This countries in the world railway Ballast track generallys use concrete crosstie.But concrete crosstie also will appear transverse crack, longitudinal crack, tight
Weight chip off-falling, rail support groove and pillow base concrete conquassation etc. diseases, when serious even occur sleeper fracture, crack perforation cause sleeper to lose
Effect, jeopardizes traffic safety.
CN102864698A discloses a kind of armored concrete railroad sleeper, and its underpart is armored concrete matrix, top
For steel protective layer.A pair of of mounting seat is set on steel protective layer, passes through fastener fixing rail.In train operation, due to
Elasticity between rail and steel protective layer is very poor, and train, rail and sleeper can generate very big vibration and noise.
CN102864698A also proposes to fill crash roll between armored concrete matrix and steel protective layer.Based on subtracting vibration isolation principle,
Though the stability of the crash roll energy reinforcing steel bar concrete substrate of filling, will increase train, rail and steel protective layer instead
Vibration and noise, bring adverse effect to driving.In addition the type sleeper not can solve reinforced concrete body cracking and pressure still
Routed problem.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel sleeper of encased steel plate, overcome the deficiencies in the prior art is simultaneous
Have the advantages of concrete crosstie and steel sleeper, improves bending resistance, resistance to compression, cracking resistance and the durability of sleeper.
The technical solution of the utility model is:A kind of Novel sleeper of encased steel plate, the composite sleeper include the steel of outsourcing
Plate and built-in concrete;The encased steel plate is arranged in the top surface, bottom surface and side of sleeper, also serves as template;Encased steel plate with
Built-in concrete transmits interface shear stress by shear connector.
Encased steel plate is arranged in the top surface, bottom surface and side of sleeper, and rail support groove section bottom surface and side steel plate locally thicken.
Bottom surface and side encased steel plate are a monolith steel plate, and by being bent to form flute profile, top surface steel plate and side steel plate are logical
Cross welded connecting.
The composite sleeper top surface steel plate disconnects at rail support groove.
Encased steel plate top plate and bottom plate and side wall inner surfaces are equipped with shear connector, between shear connector form can use
Every the peg of 10-15cm, floor can also be used.
Composite sleeper inner concrete ontology is equipped with anticracking steel fibre.
The utility model has the advantage of:The composite sleeper energy overcome the deficiencies in the prior art of the encased steel plate of proposition, is applied
Work is convenient, lower relative to steel sleeper cost, and has preferable bending resistance, resistance to compression, cracking resistance and durability.Furthermore, it is possible to contract
The area of section of small existing concrete sleeper, can also be using the sleeper section of rule.In turn, due to the protection of encased steel plate,
Sleeper cracking and chip off-falling are avoided, the durability of sleeper, the maintenance cycle of extension wire are improved.

Specific embodiment
Below with reference to example and referring to attached drawing, the invention will be further described.
Embodiment 1
The utility model provides a kind of Novel sleeper of encased steel plate, to improve the bending resistance, resistance to compression, crack resistance of sleeper
Energy and durability.As shown in Figs 1-4, the present embodiment includes the steel plate 100 and built-in concrete 200 of outsourcing.100 cloth of encased steel plate
It sets in the top surface, side and bottom surface of sleeper, also serves as template, while the bending resistance of sleeper, cracking resistance can be improved.Composite sleeper bottom
