Description
Technical field
The utility model relates to railroad sleeper, particularly a kind of for gauge 1676mm, the prestressed reinforced concrete tie of the traffic conditions such as heavy duty, heavy type or the inferior heavy railway of the heavy 25t of axle.
Background technology
The sleeper that 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.Wherein, concrete sleeper has long service life, and stability is high, and cost is relatively low, and the feature such as the little and damage ratio of maintenance work amount and scrappage are low, is therefore worldwide widely adopted.
At present, use in the world the country of broad gage sleeper to mainly contain the states such as Russia, Mongolia, Finland, the domestic railway engineering that does not still adopt broad gage sleeper of China.Existing 1676mm broad gage prestressed reinforced concrete tie structurally comprises two rail support grooves that are arranged at sleeper upper surface, pre-buried two threaded sleeves in each rail support groove, threaded sleeve mesopore is railway spike installing hole, lays prestressed reinforcement in pillow along vertical and horizontal interval, cross section.Have the deficiency of following several aspects, railway spike installing hole is blind hole, and easily ponding causes railway spike to get rusty; Easily fall into foreign material in threaded sleeve, remove very trouble; The pillow end is smooth flat, and sleeper resistance is little, and track stability is poor, is unfavorable for laying gapless track; The eccentric throw of pillow middle section prestressed reinforcement is generally below 10mm, and hogging moment resistivity is lower.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of broad gage prestressed reinforced concrete tie, to meet gauge 1676mm, and the needs of the traffic conditions such as heavy duty, heavy type or the inferior heavy railway of the heavy 25t of axle.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Broad gage prestressed reinforced concrete tie of the present utility model, comprise the sleeper with two rail support grooves, in each rail support groove, interval arranges two railway spike installing holes, it is characterized in that: described railway spike installing hole is by straight-through sleeper bottom surface, rail support groove surface, railway spike installing hole top is formed by the mesopore that is embedded in advance the threaded sleeve in sleeper, and threaded sleeve periphery is embedded with spiral wire.
The beneficial effects of the utility model are, the straight-through sleeper of railway spike installing hole bottom surface, be convenient to rain drainage and ensure that inside pipe casing is without ponding, ensure the railway spike non-corrosive of fastener, reasonable Arrangement prestressed reinforcement and position of form center, improve sleeper pillow middle section bending bearing capacity, can meet well gauge 1676mm, the needs of the traffic conditions such as heavy duty, heavy type or the inferior heavy railway of the heavy 25t of axle.Sleeper bottom surface along its length interval arranges embossed channel, and the ability of circuit resistance is provided to increase sleeper, and stablizing of track, is conducive to lay gapless track.

Zero member shown in figure, toponym and corresponding mark: 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.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See figures.1.and.2, broad gage prestressed reinforced concrete tie, comprises the sleeper 10 with two rail support grooves 11, and the interior interval of each rail support groove 11 arranges two railway spike installing holes 12.With reference to Fig. 1 and Fig. 3, described railway spike installing hole 12, by rail support groove 11 straight-through sleeper 10 bottom surfaces, surface, is convenient to rain drainage and is ensured that inside pipe casing, without ponding, ensures the railway spike non-corrosive of fastener.Railway spike installing hole 12 tops are formed by the mesopore that is embedded in advance the threaded sleeve 13 in sleeper 10, are convenient to fastener system and change.Be embedded with spiral wire 15 in threaded sleeve 13 peripheries, strengthened the supporting capacity at this place, ensured the pulling test strength at railway spike installing hole 12 places.
With reference to Fig. 3 and Fig. 4, the design outline size of sleeper 10 is as follows:
Rail support groove cross-sectional shape size: length × bottom width × height: 2800mm × 290mm × 220mm;
Pillow middle section appearance and size: length × bottom width × height: 2800mm × 290mm × 195mm.
Described sleeper 10 is formed by C60 grade filling concrete, lays 10 prestressed reinforcements 21 in it along vertical and horizontal interval, cross section, and prestressed reinforcement 21 adopts Φ 7mm1750Mpa underrelaxation high-strength prestress indented wire conventionally.According to the large feature of moment of flexure in broad gage sleeper pillow, in prestressed reinforcement configuration, suitably improve the distance of the prestressed reinforcement centre of form to sleeper lower limb position according to calculating, strengthen the ability of sleeper pillow middle section opposing hogging moment, the eccentric throw of its pillow middle section prestressed reinforcement is 14.3mm, pillow middle section presstressed reinforcing steel point of resultant force is 107mm to cross section lower limb distance, and the pillow middle section centre of form to cross section lower limb distance is 92.7mm.
With reference to Fig. 6 and Fig. 7, according to sleeper loading characteristic, in described sleeper 10,14 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 broad gage 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.
