Description

A kind of Novel sleeper of encased steel plate
Technical field
The present invention relates to railroad track technical fields, and in particular to a kind of novel compositions sleeper of encased steel plate.
Background technology
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 centainly Elasticity and insulating properties, and ensure 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 larger vertically and horizontally resistance can be provided, but its steel using amount is big, cost of manufacture is high, and it is big to be easy to corrosion, noise, so making It is limited by larger with range.Concrete crosstie service life is long, track stability is good, can meet high speed, large conveying quantity requirement, because This countries in the world railway Ballast track generally uses 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, rail is fixed by fastener.In train operation, due to Elasticity between rail and steel protective layer is very poor, and train, rail and sleeper will produce prodigious 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 cannot still solve armored concrete matrix cracking and pressure Routed problem.
Invention content
The purpose of the present invention is to provide a kind of novel compositions 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 scheme is that:A kind of novel compositions sleeper of encased steel plate, the composite sleeper include the steel of outsourcing Plate and internal fill concrete;The encased steel plate is arranged in the top surface, bottom surface and side of sleeper, also serves as template;Covered with Angles Plate transmits interface shear stress with built-in concrete 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 is a monoblock steel plate with side encased steel plate, and by being bent to form flute profile, top surface steel plate is logical with side steel plate It crosses and is welded to connect.
The composite sleeper top surface steel plate disconnects at rail support groove.
Encased steel plate top plate and bottom plate is equipped with shear connector with side wall inner surfaces, between shear connector form may be used Every the peg of 10-15cm, floor can also be used.
Composite sleeper inner concrete ontology is equipped with anticracking steel fibre.
The advantage of the invention is that:The composite sleeper energy overcome the deficiencies in the prior art of the encased steel plate of proposition, construction party Just, relatively low relative to steel sleeper cost, and there is preferable bending resistance, resistance to compression, cracking resistance and durability.Furthermore, it is possible to reduce existing There is the area of section of concrete sleeper, the sleeper section of rule can also be used.In turn, it due to the protection of encased steel plate, avoids Sleeper cracking and chip off-falling, improve the durability of sleeper, the maintenance cycle of extension wire.

Specific implementation mode
With reference to example and with reference to attached drawing, the invention will be further described.
Embodiment 1
The present invention provides a kind of novel compositions sleeper of encased steel plate, to improve the bending resistance of sleeper, resistance to compression, cracking resistance and Durability.As shown in Figs 1-4, the present embodiment includes the steel plate 100 and inner concrete 200 of outsourcing.Encased steel plate 100 is arranged in Top surface, side and the bottom surface of sleeper also serve as template, while can improve the bending resistance of sleeper, cracking resistance.Composite sleeper bottom surface and Side encased steel plate 100 locally thickeies 0.5-1cm in rail support groove section, and top surface steel plate disconnects at rail support groove.In encased steel plate 100 Top plate, side plate and baseplate inner surface pass through welding peg shear connector 110, adjacent peg interval 10-15cm be set.Peg conduct Shear connector can transmit encased steel plate and wrap up the interface shear stress between concrete.
Distributing bar 300 is set on the top, middle part and lower position of composite sleeper, distributing bar 300 is straight line configuration. For the position of fixture construction reinforcing bar 300, several stirrups 310, distributing bar 300 and stirrup are horizontally arranged in distributing bar 310 phases are bound, and see Fig. 7.It is internally provided with anticracking steel fibre 400 in the composite sleeper, this anticracking steel fibre can effectively subtract The cracking of concrete built in few sleeper.
The construction procedure of the novel compositions sleeper of this encased steel plate is as follows:
Encased steel plate 100 is made, in the top plate of encased steel plate 100, side plate and baseplate inner surface weld stud shear connector 110.
It arranges distributing bar 300, stirrup 310 and the binding of distributing bar 300 is formed into framework of steel reinforcement.
Arrange anticracking steel fibre 400.
Casting concrete forms the novel compositions sleeper of encased steel plate.
Embodiment 2
As seen in figs. 5-6, in this embodiment, the shear connector between encased steel plate 100 and built-in concrete 200 is adopted With the form of floor shear connector 120, top surface, side, bottom surface encased steel plate shear connector be staggeredly arranged, remaining structure with Reinforcing plan is consistent with embodiment 1.
The embodiment of invention described above, is not intended to limit the scope of the present invention..It is any in this hair Modifications, equivalent substitutions and improvements etc. made by within bright spirit and principle should be included in the claim protection of the present invention Within the scope of.
