Abstract
The utility model belongs to railway technology field, specifically discloses a kind of High-strength concrete sleeper.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 disposed with cushion coat from top to bottom, reinforcing bar stratum reticulare, back-up coat, reinforcing bar stratum reticulare, elastic layer in this structure.The beneficial effects of the utility model: the multi-stratification of structure, improve the intensity of sleeper, reduce the thickness of sleeper entirety simultaneously, decrease sleeper weight, save material; The elastic layer of structure in addition, makes to cross at train to reduce impact shock, alleviates 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 concrete high-intensity performance.
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;
Connector is connected with concrete support block;
The cross section of described concrete support block is U-shaped structure, is disposed with insulating layer from top to bottom, reinforcing bar stratum reticulare, back-up coat, reinforcing bar stratum reticulare, elastic layer in this structure.
Further, described insulating layer adopts electrically insulating material to make.
Further, described reinforcing bar stratum reticulare is form diamond checks network.
Further, described back-up coat adopts steel plate to form.
Further, described elastic layer adopts igelite to form.
The beneficial effects of the utility model are: the multi-stratification of structure, improve the intensity of sleeper, reduce the thickness of sleeper entirety simultaneously, decrease sleeper weight, save material; The elastic layer of structure in addition, makes to cross at train to reduce impact shock, alleviates 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 structural diagram.
In accompanying drawing, the list of parts representated by each label is as follows:
100, concrete support block, 110, insulating layer, 120, reinforcing bar stratum reticulare, 130, back-up coat, 140, reinforcing bar stratum reticulare, 150, elastic layer, 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 disposed with insulating layer from top to bottom, reinforcing bar stratum reticulare, back-up coat, reinforcing bar stratum reticulare, elastic layer in this structure.
Further, described insulating layer adopts electrically insulating material to make.
Further, described reinforcing bar stratum reticulare is form diamond checks network.
Further, described back-up coat adopts steel plate to form.
Further, described elastic layer adopts igelite to form.
As shown in Figure 2, be the utility model concrete support block structural diagram.
The beneficial effects of the utility model are: the multi-stratification of structure, improve the intensity of sleeper, reduce the thickness of sleeper entirety simultaneously, decrease sleeper weight, save material; The elastic layer of structure in addition, makes to cross at train to reduce impact shock, alleviates 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.
