Abstract
The utility model discloses a non-shoulder dual-block sleeper which is formed to an enblock by connecting two concrete units 2 using a reinforcing steel truss 1; wherein the crosssection of the reinforcing steel truss 1, which is positioned between the two concrete units, presents a M-shape with a middle part fracture; each border of the two parts of the M-shaped section are all welded with reinforcing steels at two ends; the reinforcing steels of the reinforcing steel truss 1 passing through the concrete units 2 are all positioned inside of the concrete units. The utility model has low cost and firm structure, and is mainly used for the tall section of track structure.
Description
Technical field
The utility model relates to the high-speed rail technology field, especially relates to a kind of non-shoulder double-block type sleeper that is applicable to that the high-speed railway ballastless track uses.
Background technology
China railways generally adopts ballasted track, and ballasted track makes railway roadbed lax gradually because of the effect repeatedly of bullet train, smooth-going degree variation, and maintenance activity strengthens, and the high speed development of needed workload of maintenance and time obstruction railway.The domestic track structure that also has the examination shop to be close to no circuit maintenance activity, but because of the operating expenses height, speed of application is slow, and substructure in case distortion trimming difficulty etc. also only limits to some special locations.
Brute force propelling along with China's Line for Passenger Transportation and speed-raising strategy, it is more apparent urgent with the development of construction a complete set of equipment to quicken the ballastless track construction technology, China designs and has produced double-block type sleeper by railway science institute and eight innings of cooperations of middle iron at first, needs at Chinese Railway circuit transmission distance in the process of development have carried out continuous improvement, by research more than a year, design and production, track circuit that is tested to unit plate and the test of railway roadbed leak resistance from single double-block type sleeper, always in continuous improvement, improve the structural performance of double-block type sleeper and to the compliance of track circuit, the transition of the double-block type series of products of present design is finished in guidance, and it is for adapting to a kind of novel ballastless track sleeper structural shape that Chinese track circuit transmission form is researched and developed.
Summary of the invention
It is low that the purpose of this utility model provides a kind of cost, well-set non-shoulder double-block type sleeper.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of non-shoulder double-block type sleeper, this sleeper connects and composes an integral body by a steel bar girder with two concrete blocks, steel bar girder section between two concrete blocks is the M font that the middle part disconnects, the two ends that are separated into two-part every limit in the M font all are welded with reinforcing bar, and the reinforcing bar that passes the steel bar girder of concrete block all is positioned at concrete block.
Described steel bar girder is made of four main reinforcements of two main reinforcements in top and bottom surface, be welded with respectively between steel bar girder top two reinforcing bars in concrete block and the outside, bottom surface two reinforcing bars and be oblique S shape reinforcing bar, on the two inboard reinforcing bars of bottom surface, be welded with the reinforcing bar that is hook-shaped respectively, stretch out outside the steel bar girder upper end of this hook-shaped reinforcing bar, and its lower end is welded on the inboard reinforcing bar of steel bar girder bottom surface.
Be embedded with 2 ambroin sleeve pipes in described each concrete block.
Described sleeper is rested the head on high 220mm, and long 2.5mm is positioned at the thick 240～350mm of railway roadbed board concrete of sleeper bottom.
The utility model is to be embedded in the important structure part that is used for fixing fastener, rail and transmission train load in the ballastless track concrete road bed board, the accuracy of gauge when its high-precision manufacturing requirement can guarantee to lay a railway track, the truss bars that exposes can guarantee to be connected firmly the reliability that is tightly linked with the railway roadbed board concrete; Non-prestressed structure design can reduce STRESS VARIATION complicated in the railway roadbed and reduce the generation of concrete cracks.The main steel bar stress truss of the utility model double-block type sleeper is below sleeper, can not form return curcuit (no circulation steel bar girder) in the certain limit, single truss structure reinforcing bar adopts acyclic special structure treatment of banising muscle can eliminate the influence of the mutual inductance of reinforcing bar and the generation of track circuit electric current to ballastless track circuit transmission length.
The utility model not only can satisfy the structural requirement of ballastless track and construction is simply cheap, and can satisfy the requirement of China's track circuit transmission range; It is simple that this double-block type does not have quarrel sleeper production technology, and cost is low, has the very high use value of applying.This sleeper technological achievement is that China railways reaches the international railway advanced level and has directive function, for solid technical foundation has been established in China's ballastless track technical development.

The specific embodiment
The structure of a kind of non-shoulder double-block type sleeper of the utility model such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: mainly constitute by a steel bar girder 1, two concrete blocks 2, this sleeper connects and composes an integral body by a steel bar girder 1 with two concrete blocks 2, wherein 1 section of the steel bar girder between two concrete blocks is the M font that the middle part disconnects, the two ends that are separated into two-part every limit in the M font all are welded with reinforcing bar, and the reinforcing bar that passes the steel bar girder 1 of concrete block 2 all is positioned at concrete block.Described steel bar girder 1 is made of four main reinforcements of two main reinforcements in top and bottom surface, be welded with respectively between steel bar girder 1 top, two reinforcing bars in concrete block 2 and the outside, bottom surface two reinforcing bars and be oblique S shape reinforcing bar a, on the two inboard reinforcing bars of bottom surface, be welded with the reinforcing bar b that is hook-shaped respectively, stretch out outside the steel bar girder upper end of this hook-shaped reinforcing bar, and its lower end is welded on the inboard reinforcing bar of steel bar girder bottom surface.
Be embedded with 2 ambroin sleeve pipes 3 in each concrete block 2, pre-buried 4 ambroin sleeve pipes are used for fixing rail fastening in the concrete.Described sleeper is rested the head on high 220mm, and long 2.5mm is positioned at the thick 240～350mm of railway roadbed board concrete of sleeper bottom.Use plastic bushing and plastic cushion insulating reinforcing steel bars crosspoint when the sleeper steel bar girder is connected with railway roadbed slab muscles and bones frame in the utility model, and the binding wire assembling reinforcement of use insulation in steel bar girder, the upper and lower layer of road bed board reinforcing bar adopts the treatment measures that insulate between reinforcing bar, and the utility model is used to consider the section to the influence of resonant mode track circuit.
