Abstract
The utility model discloses a concrete sleeper which comprises a sleeper body. The concrete sleeper is characterized in that two prepared holes are respectively arranged inside the both sides of the center of the sleeper body; internal screw threads are arranged in the prepared holes; the internal screw threads in the prepared holes are matched with external screw threads arranged on spike bolts; bushing blocks are embedded on the bottom surfaces of both sides of the center of the sleeper body; the planes of the bottommost ends of the bushing blocks and the plane of the bottommost end of the sleeper body are positioned on the same horizontal plane; the bottom surfaces of the bushing blocks are provided with elastic rubber base plates; the bottom surfaces of the bushing blocks are provided with grooves; the tops of the elastic rubber base plates are provided with bumps; and the grooves are matched with the bumps. The concrete sleeper has the advantages that the concrete sleeper is highly elastic, is difficult to deform and is convenient to disassemble and install; the production cost is reduced; the geometry keeping capacity of the sleeper can be effectively improved; the reinforcement using quantity is reduced; the constructability is improved; the requirement of the sleeper on the crankling resistance capacity is met; and the concrete sleeper is beneficial to popularization and application.
Description
Technical field
The utility model relates to the concrete application, relates in particular to a kind of concrete sleeper.
Background technology
Sleeper is one of vitals in the track structure, is laid on to be used for supporting rail on the railway roadbed.The effect of sleeper is the pressure that bears from rail, and this pressure is spread in railway roadbed, thereby effectively keeps the track geometry of track.Sleeper should supporting rail, and the position that keeps again rail also will pass to railway roadbed to the immense pressure that the rail transmission comes again.It must possess certain pliability and elasticity, and is hard not all right, soft also not all right.Train is through out-of-date, and it can suitably be out of shape with compensator or trimmer pressure, but train must restore to the original state later as far as possible.Yet sleeper of the prior art also exists following shortcoming: rigidity is large, and poor flexibility is yielding, removes and installs difficulty, wastes time and energy, and consumes steel many, has increased cost of production.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this utility model provides a kind of concrete sleeper.
The technical solution adopted in the utility model is:
A kind of concrete sleeper, comprise the sleeper body, inside, both sides, described sleeper body center is equipped with two preformed holes, be provided with internal thread in the described preformed hole, internal thread in the described preformed hole cooperatively interacts with the external screw thread of being located on the railway spike bolt, bottom surface, both sides, described sleeper body center studs with lining, and described lining lowermost end plane and sleeper body lowermost end plane are positioned at same level.
Described lining bottom surface is provided with the elastic caoutchouc backing plate.
Described lining bottom surface is provided with groove, and described elastic caoutchouc backing plate top is provided with projection, and described groove and projection cooperatively interact.
The utility model has the advantages that: good springiness, not yielding, remove and install conveniently, reduced cost of production, but can effectively increase sleeper track geometry hold facility, reduce amount of reinforcement and raising application property, satisfy sleeper bending-twisting Capability Requirement, be conducive to apply.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model lining.
Wherein: 1, sleeper body, 2, preformed hole, 3, internal thread, 4, external screw thread, 5, the railway spike bolt, 6, lining, 7, the elastic caoutchouc backing plate, 8, groove, 9, projection.
The specific embodiment
As illustrated in fig. 1 and 2, a kind of concrete sleeper of the present utility model, comprise sleeper body 1, inside, both sides, described sleeper body 1 center is equipped with two preformed holes 2, be provided with internal thread 3 in the described preformed hole 2, internal thread 3 in the described preformed hole 2 cooperatively interacts with the external screw thread 4 of being located on the railway spike bolt 5, bottom surface, both sides, described sleeper body 1 center studs with lining 6, described lining 6 lowermost end planes and sleeper body 1 lowermost end plane are positioned at same level, described lining 6 bottom surfaces are provided with elastic caoutchouc backing plate 7, described lining 6 bottom surfaces are provided with groove 8, described elastic caoutchouc backing plate 7 tops are provided with projection 9, described groove 8 cooperatively interacts with projection 9, and good springiness is not yielding, remove and install conveniently, reduce cost of production, can effectively increase sleeper track geometry hold facility, but reduce amount of reinforcement and raising application property, satisfy sleeper bending-twisting Capability Requirement, be conducive to apply.
