Abstract
The utility model discloses a kind of High-strength concrete sleeper, belong to railway technology field, it comprises: concrete support block and connector, and connector is connected with concrete support block; The cross section of described concrete support block is U-shaped structure, is provided with band double-layer plate with dissection in this structure, is provided with several inverted triangle steel plates and is connected composition between this steel plate; The beneficial effects of the utility model: sleeper adopts wider bottom surface structure to contact with railway roadbed, increases lifting surface area, and be provided with two-layer bar construction in the concrete of this wider portion, improve the intensity of sleeper, reduce the thickness of sleeper entirety simultaneously, decrease sleeper weight, save material; Be fixedly connected with elastic layer in the bottom surface of horizontal mounting arm in addition, make to cross at train to reduce impact shock, alleviate the impact force to railway roadbed, reduce noise simultaneously.
Description
Technical field
The utility model relates to a kind of railway equipment technical field, particularly relates to a kind of High-strength concrete sleeper
Background technology
Modern railways transport is more and more stricter to the requirement of track, as high ride, high stability, high-durability, and improve constantly along with existing railway construction level, the use standard tackling railway roadbed mutually also constantly strengthens, as high planarization, low deformability, the high-performance of railway roadbed itself is that rail transport provides favourable condition; And for the higher railway roadbed of planarization, existing sleeper is not well suited for, sleeper forced position settles rail place at two ends, and mid portion plays the effect of reinforcement unitarity sleeper, but there is the wasting of resources for the good railway roadbed of planarization.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of High-strength concrete sleeper, realizes alleviating sleeper weight, economizes on resources, and realizes the holding capacity strengthening sleeper.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of High-strength concrete sleeper, comprising: concrete support block and connector;
Described connector is connected with concrete support block;
The cross section of described concrete support block is U-shaped structure, is provided with band double-layer plate with dissection in this structure, is provided with several inverted triangle steel plates and is connected composition between described double-layer plate.
Further, described concrete support block bottom surface is provided with elastic layer.
Preferably, described elastic layer adopts foamed thermoplastic material.
The beneficial effects of the utility model are: sleeper adopts wider bottom surface structure to contact with railway roadbed, increases lifting surface area, and be provided with two-layer bar construction in the concrete of this wider portion, improve the intensity of sleeper, reduce the thickness of sleeper entirety simultaneously, decrease sleeper weight, save material; Be fixedly connected with elastic layer in the bottom surface of horizontal mounting arm in addition, make to cross at train to reduce impact shock, alleviate the impact force to railway roadbed, reduce noise simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model concrete support block structure schematic diagram.
In accompanying drawing, the list of parts representated by each label is as follows:
100, concrete support block, 110, steel plate, 120, inverted triangle steel plate, 130, steel plate, 200, connector.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of High-strength concrete sleeper, comprising: concrete support block and connector;
Described connector is connected with concrete support block;
The cross section of described concrete support block is U-shaped structure, is provided with band double-layer plate with dissection in this structure, is provided with several inverted triangle steel plates and is connected composition between described double-layer plate.
Further, described concrete support block bottom surface is provided with elastic layer.
Preferably, described elastic layer adopts foamed thermoplastic material.
As shown in Figure 2, the utility model concrete support block structural diagram.
Compared with prior art, the beneficial effects of the utility model are: sleeper adopts wider bottom surface structure to contact with railway roadbed, increase lifting surface area, and in the concrete of this wider portion, be provided with two-layer bar construction, improve the intensity of sleeper, reduce the thickness of sleeper entirety simultaneously, decrease sleeper weight, save material; Be fixedly connected with elastic layer in the bottom surface of horizontal mounting arm in addition, make to cross at train to reduce impact shock, alleviate the impact force to railway roadbed, reduce noise simultaneously.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
