Abstract

The utility model relates to a prestressed concrete sleeper with a strengthened shoulder, comprising a steel fiber concrete sleeper. The point that a sleeper groove which is laid with a steel rail (namely, the shoulder point) is provided with an iron pad. The iron pad has at least 10 round steel bars, and the steel bars are extended into the steel fiber concrete sleeper. Because the shoulder point of the concrete sleeper laid with the steel rails is provided with the iron pad with the round steel bars, partial pressure and impact force stressed by a sleeper supporting groove point can be transferred to the whole sleeper through the steel bars, so that impact force and pressure resistance at the sleeper supporting groove point can be strengthened. Besides, the iron pad can cause the pressure bearing area of the shoulder point of the sleeper supporting groove to be enlarged. Simultaneously, the impact resistance and the pressure resistance of the sleeper can be enhanced, and the service life of the sleeper can be prolonged.

Description

The strengthened shoulder type prestressed reinforced concrete tie

The utility model relates to a kind of sleeper, exactly relates to a kind of strengthened shoulder type prestressed reinforced concrete tie.

The shoulder block place anti-impact force of present concrete sleeper is not strong, usually is subject to damage, and particularly the sweep in the mountain area is little, the place that the gradient is big, and the problems referred to above are more obvious.

The purpose of this utility model overcomes the deficiencies in the prior art exactly, and a kind of strengthened shoulder type prestressed reinforced concrete tie is provided, and it can improve the shock resistance of sleeper, measuring body power energy, thereby has improved the quality of railway, has guaranteed the traffic safety of train.

The purpose of this utility model realizes by following technical proposals, strengthened shoulder type prestressed reinforced concrete tie of the present utility model comprises a steel fibrous concrete pillow, the rail groove position of steel rail laying thereon, promptly be provided with iron gasket at its shoulder block place, described iron gasket has at least 10 round reinforcing bars, and these reinforcing bars are extended to the steel fibrous concrete pillow.

Round reinforcing bar on the above-mentioned iron gasket is a kind of indented bars, and wherein at least 6 round reinforcing bars are perpendicular to and stretch downwards, and at least 4 round reinforcing bars at the iron gasket portion of bending up place is within the oblique concrete crosstie that stretches.

The utility model has the advantages that owing to be arranged at iron gasket with round reinforcing bar at the shoulder block place of the steel rail laying of concrete crosstie, make sleeper rail support groove place be subjected to partial pressure and impact force to be passed to whole sleeper by its reinforcing bar, thereby the anti-impact force and the anti-pressure ability at sleeper rail support groove place have been strengthened, iron chair also makes the pressure-bearing surface at rail support groove shoulder block place increase in addition, the shock resistance and the anti-pressure ability of its sleeper have also been improved simultaneously, the application life of having improved sleeper.

Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein

Fig. 1 is the structural representation of sleeper of the present utility model;

Fig. 2 is the schematic diagram of iron gasket.

Now referring to accompanying drawing 1 and Fig. 2, strengthened shoulder type prestressed reinforced concrete tie of the present utility model comprises a steel fibrous concrete pillow 1, the rail groove place of steel rail laying thereon, promptly be provided with iron gasket 2 at its shoulder block place, described iron gasket 2 has at least 10 round reinforcing bars 3, and these reinforcing bars 3 are extended (burying underground) to steel fibrous concrete and rest the head within 1.In a preferred embodiment, described reinforcing bar 3 is to be provided with like this, and wherein at least 6 reinforcing bars 3 extend vertically downward, and at least 4 reinforcing bars 3 are obliquely extended within the concrete crosstie 1 according to iron gasket 2 portions of bending up place.The reinforcing bar 3 of oblique extension in a preferred embodiment is shorter than the reinforcing bar 3 that extends vertically downward.

Claims

1, a kind of strengthened shoulder type prestressed reinforced concrete tie is characterized in that it comprises a steel fibrous concrete pillow.The rail groove position of steel rail laying promptly is provided with iron gasket at its shoulder block place thereon, and described iron gasket has at least 10 round reinforcing bars, and these reinforcing bars are extended to the steel fibrous concrete pillow.

2, sleeper according to claim 1, it is characterized in that the round reinforcing bar on the above-mentioned iron gasket is a kind of indented bars, wherein at least 6 round reinforcing bars are perpendicular to and stretch downwards, and at least 4 round reinforcing bars at the iron gasket portion of bending up place are within the oblique concrete crosstie that stretches.
