Abstract
The utility model discloses a tram ballastless track is short sleeper of concrete for system, include, bear the rail with the installation fastener short sleeper piece and anchor connecting reinforcement, short sleeper piece is the terrace with edge structure, and anchor connecting reinforcement one end is buried underground in short sleeper piece, and the other end sets up inside concrete. The beneficial effects are that: the short sleeper piece of terrace with edge structure can effectively increase the contact force between sleeper and the railway roadbed, has improved the wholeness of railway roadbed, short sleeper piece bottom surface sets up V style of calligraphy slope, and during railway roadbed concrete placement, the accessible vibrates and realizes the requirement of the closely knit degree of concrete, the shaped steel muscle of buckling effectively increases being connected between sleeper and railway roadbed concrete, and it is as an organic whole to make short sleeper and concrete pour, effectively solves short sleeper and is connected the clearance leakage with the concrete concrete, and the railway roadbed appears around the short sleeper crackle, weak point sleeper become flexible the scheduling problem, and structural integrity is better in the track system.
Description
Technical field
The sleeper of the utility model ballastless track system; Particularly relate to the short sleeper of a kind of modern tram ballastless track system.
Background technology
Short sleeper type ballastless track structure is simple, and cost is relatively low, and flexibly, construction precision can ensure, construction costs is lower in field operation construction.The short sleeper of current application does not mate with tram fastener system, and short sleeper exists and loosens, and there is the phenomenon of crackle between short sleeper and solid concrete roabed contact surface around the easy to crack and short sleeper of road bed board.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of combination strengthening short sleeper and solid concrete roabed, improves the globality of railway roadbed, durability and the short sleeper of urban track traffic non-fragment orbit concrete in application life.
The technical scheme that the utility model adopts is: the short sleeper of a kind of tram ballastless track system concrete, comprises, the short sleeper block of carrying rails and fastener for installing and anchor connection reinforcing bar; Described short sleeper block is terrace with edge structure, and anchor connection reinforcing bar one end is embedded in short sleeper block, and the other end is arranged at solid concrete roabed inside.
Described short sleeper block comprises, and the inclined plane of end face, bottom surface and main body both sides, described end face is less than bottom surface, and bottom surface is V-shape slope, and end face both sides are formed with shoulder block.
Be embedded with fastener insulating sleeve in described short sleeper block, around insulating sleeve, be provided with spiral reinforcement.
Described connecting reinforcement is bent; The end face of short sleeper block and plane-parallel.
The beneficial effects of the utility model are: the short sleeper block of terrace with edge structure effectively can increase the contact force between sleeper and railway roadbed, improves the globality of railway roadbed; Short sleeper block bottom surface arranges V-shape slope, during railway roadbed concreting, realizes the requirement of concrete density by vibrating; Bending type reinforcing bar effectively increases the connection between sleeper and railway roadbed concrete, short sleeper and solid concrete roabed are built be integrated, the short sleeper of effective solution is connected not tight with solid concrete roabed concrete, the problems such as the crackle that around short sleeper, railway roadbed occurs, short sleeper loosen, rail system structural integrity is better.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1 to Figure 3, the short sleeper of the utility model tram ballastless track system concrete, comprises, the short sleeper block 1 of carrying rails and fastener for installing and anchor connection reinforcing bar 5; Described short sleeper block 1 is in terrace with edge structure, comprise the inclined plane 3 of end face, bottom surface and main body both sides, end face and plane-parallel, end face is less than bottom surface, that is, the distance towards bottom surface 6 between two inclined planes 3 between end face and bottom surface 6 increases gradually, effectively can increase the contact force of sleeper and railway roadbed, strengthen the combination of short sleeper and railway roadbed, improve the globality of railway roadbed; Bottom surface is V-shape slope, during railway roadbed concreting, realizes the requirement of concrete density by vibrating; Short sleeper block end face both sides are formed with shoulder block 2, and shoulder block wants the requirement that can meet fastener Interface design, also can adjust according to the requirement of different fastener interface.
Anchor connection reinforcing bar 5 one end is embedded in short sleeper block 1, the other end is arranged at solid concrete roabed inside, connecting reinforcement 5 is in bent, bending type reinforcing bar effectively can increase the connection between sleeper and railway roadbed concrete, short sleeper and solid concrete roabed are built be integrated, effectively can solve short sleeper is connected tight with solid concrete roabed concrete, the problems such as the crackle that around short sleeper, railway roadbed occurs, short sleeper are loosening; Fastener insulating sleeve 4 is embedded with in described short sleeper block 1, spiral reinforcement 7 is provided with around insulating sleeve, it is inner that pre-buried insulating sleeve is positioned at short concrete sleeper, and concordant with sleeper surface or the outstanding end face in surface, arranges the uplift force that spiral reinforcement can increase insulating sleeve around insulating sleeve.
The short sleeper agent structure of the utility model is rest pad and anchor connection reinforcing bar, and rest pad profile is simple, and Mold Making is easy, and light structure is convenient to lifting, transport and section of track assembling; Short sleeper be ordinary reinforced concrete without prestressed structure, produce easily prefabricated.
The appearance and size (length, width and height) of short sleeper, the reinforcing bar form size that short sleeper stretches out, and the degree of depth that short sleeper is imbedded in solid concrete roabed can adjust according to user's request.
The short sleeper strength grade of the utility model concrete is C50, be prefabricated in the factory, stretch out anchor connection reinforcing bar bottom short sleeper and can strengthen the connection with solid concrete roabed, between sleeper end face and bottom surface, distance between two inclined sides is increased gradually by the direction of end face towards bottom surface, such terrace with edge structure, effectively can increase the contact force of sleeper and solid concrete roabed, strengthen the combination of short sleeper and solid concrete roabed, improve the globality of solid concrete roabed, durability and application life.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to allow the technology personage being familiar with this field can understand the utility model content and be implemented, can not limit protection domain of the present utility model with this.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.
