Abstract
The utility model provides a sleeper for a ballast track. The sleeper comprises a main sleeper body. The main sleeper body is provided with through holes, fixing reinforcing steel bars can be penetratingly arranged in the through holes, and the through holes transversely penetrate through the main sleeper body. The sleeper has the advantage that the problem of instability of a sleeper for a ballastless track in the prior art is effectively solved.
Description
Technical field
The utility model is specifically related to a kind of non-fragment orbit sleeper.
Background technology
The non-fragment orbit structure that high-speed railway of the prior art generally adopts, it is strong that non-fragment orbit has durability, maintenance load is few, maintenance cost is low, advantages such as track structure stability, continuity and ride comfort are good, but situations such as non-fragment orbit in use occurs easily with sleeper and adhesive surface gap, the sleeper of concrete road bed board are loosening, cracking cause occurring the non-fragment orbit unsteady problem of sleeper.
The utility model content
The utility model aims to provide a kind of non-fragment orbit sleeper, to solve the non-fragment orbit unsteady problem of sleeper in the prior art.
To achieve these goals, the utility model provides a kind of non-fragment orbit sleeper, and sleeper comprises the sleeper main part, and the sleeper main part has be used to wearing the fixedly through hole of reinforcing bar, and through hole is along laterally running through the sleeper main part.
Further, the sleeper main part has the end face for carrying, and sleeper also comprises the built-in fitting that is installed on the sleeper main part, and an end of built-in fitting is positioned at the sleeper main part, and its other end protrudes from end face.
Further, be provided with reinforcing rib in the sleeper main part, reinforcing rib is located in the sleeper main part along the bearing of trend of sleeper main part, and stretch out from two end faces of sleeper main part respectively at the two ends of reinforcing rib.
Further, reinforcing rib is compressor wire or plain bars.
Further, through hole is a plurality of and distributes along the bearing of trend of sleeper main part.
Use the technical solution of the utility model, non-fragment orbit sleeper, sleeper comprise the sleeper main part, and the sleeper main part has be used to wearing the fixedly through hole of reinforcing bar, and through hole is along laterally running through the sleeper main part.Be used for wearing the fixedly through hole of reinforcing bar by what the sleeper side arranged reservation, when the road bed board was constructed, sleeper was embedded in the cast-in-place railway roadbed, after reinforcing bar passes through hole, reinforced concrete works pours into bed board, has increased adhesive property between sleeper and the concrete road bed board like this, makes sleeper more firm.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shows non-fragment orbit of the present utility model and looks schematic diagram with the master of the embodiment of sleeper;
Fig. 2 shows the schematic top plan view of the non-fragment orbit usefulness sleeper of Fig. 1;
Fig. 3 shows the schematic side view of the non-fragment orbit usefulness sleeper of Fig. 1.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
The utility model provides the embodiment of non-fragment orbit with sleeper, and specifically referring to Fig. 1 to Fig. 3, sleeper comprises sleeper main part 10, and sleeper main part 10 has be used to wearing the fixedly through hole 11 of reinforcing bar, and through hole 11 is along laterally running through sleeper main part 10.
By the sleeper side through hole 11 of reservation is set, during the construction of road bed board, sleeper is embedded in the cast-in-place railway roadbed, after reinforcing bar passes through hole 11, reinforced concrete works pours into bed board, has increased adhesive property between sleeper and the concrete road bed board like this, makes sleeper more firm.
Sleeper main part 10 has the end face for carrying, and sleeper also comprises the built-in fitting 20 that is installed on the sleeper main part 10, and built-in fitting 20 parts are positioned at sleeper main part 10 and protrude from end face.Sleeper links to each other with fastener by built-in fitting 20, has improved the lateral bearing power of non-fragment orbit structure, and fastener is the link that forms the section of track between rail and the sleeper, and built-in fitting is generally connectors such as preburied iron base, sleeve pipe.
Be provided with reinforcing rib 30 in the sleeper main part 10, reinforcing rib 30 is located in the sleeper main part 10 along the bearing of trend of sleeper main part 10, and stretch out from two end faces of sleeper main part 10 respectively at the two ends of reinforcing rib 30.The both ends of the surface of sleeper main part can strengthen being connected of sleeper and concrete road bed board by reinforcing rib, and the reinforcing rib 30 of present embodiment is compressor wire, and in other unshowned embodiment, reinforcing rib is plain bars etc.
Present embodiment further preferably, through hole 11 is for a plurality of and evenly distribute along the bearing of trend of sleeper main part 10.Sleeper still can satisfy the requirement of heavy haul railway non-fragment orbit circuit except satisfying common railway, high-speed railway, subway and light rail, and is applicable to various gauges laying 60kg/m, 75kg/m or other degree type rail.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
