Abstract
The utility model relates to a novel glass steel hollow sleeper, including the sleeper body, the sleeper body includes cuboid frame construction and at least one nut groove, nut groove installs in the cuboid frame construction. The beneficial effects of the utility model are that through adopting glass fiber reinforced plastic material, strengthened the hardness and the intensity on compound sleeper surface greatly, improved bearing capacity and the heavily loaded anti -fatigue ability of compound sleeper, resistant shearing force greatly. Through the groove that sets up mounting nut in the structure, through mounting nut, glass steel hollow sleeper's bolt resistance to plucking intensity has been improved greatly.
Description
Technical field
The utility model relates to railroad tracks field, particularly relates to a kind of new glass fibre reinforced plastic hollow sleeper.
Background technology
Sleeper is the one of railway casting, plays vital effect in railway construction.In track structure, the effect of sleeper bear transmitted by rail loading, lateral force and longitudinal horizontal force, it spread equably on railway roadbed, meanwhile, sleeper also plays effects such as keeping rail direction, gauge and position.Therefore, require that sleeper will have certain soundness, elasticity and durability, and require that sleeper specification is convenient to fixing rail have the ability of opposing circuit vertical, horizontal displacement.
At present, rail track adopts concrete sleeper and wooden sleeper substantially, but concrete sleeper rigidity is too many, after a long time use, easily there is crackle in product, and wooden sleeper, after the solarization of long-term wind drenches with rain and corrodes, its gauge hold facility significantly declines, and substantially, uses and just must change afterwards for 5 years.Face the decline of the supply of this railroad sleeper high-quality timber and protect forest resources, people start the research of new high-tech product composite sleeper.As the U.S. adopts waste and old PE plastics to make sleeper by surface peening, Korea S is that main material makes sleeper with junked tire, Russia with wood chip for the main research carrying out sleeper, the composite sleeper that Japan is made up of polyurethane foam and glass fiber, the domestic research also starting glass fiber reinforced plastics hollow sleeper.Although these composite sleepers have all had both the processability of wooden sleeper, and its decay resistances etc. are all excellent than wooden sleeper, but its intensity, fatigue performance, bolt pulling test strength, anti-shear performance etc. all only meet the requirement of urban track traffic sleeper, can not meet far away railroad sleeper especially heavy haul railway and high-speed railway for the requirement of the technical indicators such as sleeper carrying and fatigue test.
Utility model content
For the deficiency in current composite sleeper product technology, the purpose of this utility model is to provide a kind of new glass fibre reinforced plastic hollow sleeper, its combination property is far superior to wooden sleeper, and its bearing strength, anti-fatigue performance, bolt pulling test strength, shear strength are far superior to the composite sleeper of current urban track traffic.Effectively can replace wooden sleeper and the composite sleeper of current high-quality.Can railroad bridge be widely used in, especially heavy haul railway and high-speed railway bridge, and extend in the construction of heavy haul railway, high-speed railway, common railway, urban track traffic railway.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of new glass fibre reinforced plastic hollow sleeper, comprise sleeper body, described sleeper body comprises cuboid frame construction and at least one nut groove, and described nut groove is arranged in described cuboid frame construction.
The beneficial effects of the utility model are: by adopting glass-reinforced plastic material, greatly strengthen hardness and the intensity on compound sleeper surface, substantially increasing supporting capacity and heavily loaded anti-fatigue ability, the fingerprinting stress of compound sleeper.
By arranging the groove of mounting nuts in the structure, by mounting nuts, substantially increase the bolt pulling test strength of glass fiber reinforced plastics hollow sleeper.
On the basis of technique scheme, the utility model can also do following improvement:
Further, described nut groove is frame structure, and described frame structure inner surface is provided with the screw thread matched with bolt; The sidewall of described frame structure is fixed on the middle part of described cuboid frame construction inside upper surface.
Further, be provided with 1 ~ n vertical strengthening ribs in described cuboid frame construction, described vertical strengthening ribs to be evenly arranged in described cuboid frame construction and with described cuboid framework upper end and lower end is corresponding connects.
Further, described nut groove is quadra structure, and when described vertical strengthening ribs is even number, the sidewall of described quadra structure is fixed between two described vertical strengthening ribs in the middle part of described cuboid frame construction.
Further, described nut groove is quadra structure, and when described vertical strengthening ribs is odd number, the sidewall of described quadra structure is fixed on the middle part of described cuboid frame construction inside upper surface.
Further, the material of described cuboid frame construction is fiber-reinforced resin matrix compound material.
Further, the sidewall thickness of described cuboid frame construction is 3mm ~ 50mm.
