Description
Technical field
The utility model relates to railroad sleeper, particularly a kind of meter of gauge prestressed reinforced concrete tie.
Background technology
The sleeper that at present various countries extensively adopt mainly can be divided into three kinds of a meter gauge, standard gauge and broad gages by gauge, can be divided into the types such as concrete crosstie, sleeper, steel sleeper and synthetic resin sleeper by material.The features such as wherein, concrete sleeper has long service life, and stability is high, and cost is relatively low, and the little and damage ratio of maintenance work amount and scrappage are low, are therefore worldwide widely adopted.At present a rice rail gauge concrete sleeper has extensive employing in the world, and in China, domestic only in Yunnan, domestic area adopts to some extent, and its main supporting 43kg/m and 50kg/m rail, for time heavy and light railway transportation, design axle and are heavily no more than 16t.
Existing rice gauge prestressed reinforced concrete tie structurally comprise two rail support grooves that are arranged at sleeper upper surface, two its axis are set perpendicular to sleeper bottom surface railway spike installing hole in each rail support groove, in pillow, along vertical and horizontal interval, cross section, lay prestressed reinforcement, the eccentric throw of rail lower section prestressed reinforcement is generally below 5mm.Adopt sulfur cement mortar anchorage railway spike, in construction, sulfur cement mortar anchorage technique is seriously polluted to air ambient, and can not change after spike anchoring.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of meter of gauge prestressed reinforced concrete tie, to carry out easily installation and the replacing of fastener railway spike, and the supporting capacity of raising sleeper.It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Rice gauge prestressed reinforced concrete tie of the present utility model, comprise that the sleeper with two rail support grooves is characterized in that: pre-buried two threaded sleeves in interval in described rail support groove, threaded sleeve has screw-shaped railway spike installing hole, and the axis of railway spike installing hole becomes 5 degree acute angles with rail support groove plane vertical line.
The beneficial effects of the utility model are, can carry out easily installation and the replacing of fastener railway spike, and a bolt railway spike tension, is not subject to shear action, directly by gauge apron, wheel-rail lateral force is passed to sleeper shoulder block, is conducive to improve the supporting capacity of sleeper.

Zero member, toponym and corresponding mark shown in figure: sleeper 10, rail support groove 11, railway spike installing hole 12, threaded sleeve 13, embossed channel 14, spiral wire 15, prestressed reinforcement 21, stirrup 22, shear reinforcement 23.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See figures.1.and.2, rice gauge prestressed reinforced concrete tie of the present utility model, comprises the sleeper 10 with two rail support grooves 11.Pre-buried two threaded sleeves 13 in the interior interval of described rail support groove 11, threaded sleeve 13 has screw-shaped railway spike installing hole 12, can carry out easily installation and the replacing of fastener railway spike.The axis of railway spike installing hole 12 becomes 5 degree acute angles with rail support groove 11 plane vertical lines, can make a bolt railway spike tension, is not subject to shear action, directly by fastener gauge apron, wheel-rail lateral force is passed to sleeper shoulder block, is conducive to improve the supporting capacity of sleeper.With reference to Fig. 3, described threaded sleeve 13 peripheries are embedded with spiral wire 15, have strengthened the supporting capacity at this place, have guaranteed the pulling test strength at place, sleeper bolt hole.
With reference to Fig. 3 and Fig. 4, design outline size and the important technological parameters of sleeper 10 are as follows:
Rail support groove cross-sectional shape size: length * bottom width * height: 2000mm * 270mm * 200mm;
Pillow middle section appearance and size: length * bottom width * height: 2000mm * 270mm * 175mm;
Length of sleeper: 2m;
Positive bending moment design supporting capacity: 15.9kNm under rail.
Hogging moment design supporting capacity: 11.1kNm in pillow
Described sleeper 10 is formed by C60 grade filling concrete, lays 8 prestressed reinforcements 21 in it along vertical and horizontal interval, cross section, and prestressed reinforcement 21 adopts Φ 7mm, 1570Mpa underrelaxation high-strength prestress indented wire conventionally.According to the little feature of moment of flexure in the large pillow of rice rail gauge sleeper rail support groove moment of flexure, suitably reduce the prestressed reinforcement centre of form to the distance of sleeper lower limb position, strengthened the supporting capacity of sleeper rail lower section, its prestressing force eccentric throw in rail support groove 11 cross sections, place is 6.7mm, making rail lower section presstressed reinforcing steel point of resultant force to cross section lower limb distance is 87.5mm, and the rail lower section centre of form to cross section lower limb distance is 94.2mm.
With reference to Fig. 6 and Fig. 7, according to sleeper loading characteristic, in described sleeper 10,11 road stirrups 22 are laid at interval along its length, have promoted sleeper integrated carrying and end sleeper concrete resistance to compression anti-crack ability.Shoulder block place in rail support groove 11 outsides lays shear reinforcement 23, to strengthen the shear resistant capacity of sleeper shoulder block.With reference to Fig. 5, described sleeper 10 bottom surfaces arrange embossed channel 14 in interval along its length, and the ability of circuit resistance is provided to increase sleeper, are conducive to the stable of track, meet and lay gapless track.
Some principles of the above the utility model rice gauge prestressed reinforced concrete tie that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
