Description

Technical Field

[0001] The utility model relates to the field of sleepers, in particular to an integral roadbed. Background Art

[0002] The integral ballast is a ballast made of concrete. Wooden sleepers, concrete sleepers or short concrete sleepers can be pre-buried in the ballast. Fasteners, elastic cushions and rails can also be directly installed on the concrete integral ballast. It is also called an integral track.

[0003] The existing integral roadbed is composed of two prestressed concrete longitudinal beams and their connecting rods, transverse and longitudinal limiters to form a unique "prestressed concrete longitudinal beam + transverse connecting rod" frame structure, which not only eliminates the transverse prestress, but also simplifies the structure and manufacturing process.

[0004] The existing integral roadbed has a simple structure and installation scheme, but some problems will arise after long-term use. The biggest problem is that its shock absorption effect is poor. Therefore, after the track on it is subjected to vibration and pressure for a long time, the weak positions of the track welding are prone to tiny internal cracks under long-term slight vibrations. Once tiny internal cracks appear in the track welding, the noise will increase and there will be greater safety hazards. Therefore, it is necessary to optimize and improve the existing structure. Utility Model Content

[0005] The utility model aims to provide an integral roadbed to solve the problem that no corresponding mechanism is arranged on the existing integral roadbed to deal with the internal cracking of the rail welding position.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An integral track bed comprises two parallel concrete longitudinal beams, wherein the concrete longitudinal beams are connected to a ground foundation, the tops between the concrete longitudinal beams are evenly provided with transverse connecting rods, the lower parts between the concrete longitudinal beams are provided with a horizontal reinforcing rib net, and the tops of the concrete longitudinal beams are also provided with a track weld stabilizing mechanism, wherein the track weld stabilizing mechanism is provided corresponding to the welds of the tracks arranged on the tops of the concrete longitudinal beams.

[0008] A reinforcing rib mesh is set at the lower part between the concrete longitudinal beams to improve the stability between the two longitudinal beams, and a track weld stabilization mechanism is set at the top of the concrete longitudinal beam at the weld of the track. This can effectively protect the weld of the track and effectively improve the problem of tiny cracks that are prone to appear inside the welding joints.

[0009] As a further preferred embodiment of the present invention, longitudinal reinforcing ribs are provided in the concrete longitudinal beam, and both ends of the longitudinal reinforcing ribs are connected to fixing plates anchored in the concrete longitudinal beam structure.

[0010] The overall bearing capacity of the concrete longitudinal beam is improved, and at the same time, the two ends of the longitudinal reinforcement are connected with fixed plates to prevent the ends of the concrete longitudinal beam from cracking.

[0011] As a further preferred embodiment of the present invention, the transverse connecting rod is coated with rubber fiber concrete.

[0012] Rubber fiber concrete is wrapped around the transverse connecting rod to prevent cracking and reduce cracks between the steel pipe and the concrete beam.

[0013] As a further preferred embodiment of the present invention, the rail weld stabilization mechanism includes a flip support rod and a support plate. The flip support rod is arranged on both sides of the rail setting position, one end of the flip support rod is rotatably connected to the concrete longitudinal beam, and the support plate is rotatably arranged at the other end of the flip support rod. A screw-type fastening mechanism is provided in the middle of the flip support rod, and the lower end of the screw-type fastening mechanism passes through the flip support rod and is threadedly connected to an anchor preset at the top of the concrete longitudinal beam.

[0014] Before installing the track, turn the support plate outward. After the track is installed and welded, turn the support plate inward so that its inner end face is close to the vertical support wall of the track, and then tighten and fix it through a screw-type fastening mechanism so that the support plate can continuously apply pressure to the vertical support wall of the track. In this way, the jitter amplitude of the welding point can be greatly reduced, which enhances the stability of the place and reduces the chance of internal damage and the appearance of tiny cracks.

[0015] Compared with the prior art, the utility model can achieve at least one of the following beneficial effects:

[0016] 1. A reinforcing rib net is set at the lower part between the concrete longitudinal beams to improve the stability between the two longitudinal beams, and a track weld stabilization mechanism is set at the top of the concrete longitudinal beam at the weld of the track, which can effectively protect the weld of the track and effectively improve the problem of small cracks easily appearing inside the welding part.

[0017] 2. The overall bearing capacity of the concrete longitudinal beam is improved. At the same time, the two ends of the longitudinal reinforcement are connected with fixed plates to prevent the ends of the concrete longitudinal beam from cracking.

[0018] 3. Rubber fiber concrete is wrapped around the transverse connecting rod to prevent cracking and reduce cracks between the steel pipe and the concrete beam.

[0019] 4. Before installing the track, turn the support plate outward. After the track is installed and welded, turn the support plate inward so that its inner end face is close to the vertical support wall of the track, and then tighten and fix it through a screw-type fastening mechanism so that the support plate can continuously apply pressure to the vertical support wall of the track. In this way, the jitter amplitude of the welding point can be greatly reduced, the stability of the place is enhanced, and the chance of internal damage and the appearance of tiny cracks is reduced.
