Description
Technical Field
[0001] The utility model relates to the technical field of railway tracks, and more specifically, to a track floating plate. Background Art
[0002] Floating slabs are a support structure for railway tracks, usually used to support the tracks and fix the track positions.

The upper end surface of the limiting ring 14 and the middle position are provided with a avoiding groove 16, and the inside of the avoiding groove 16 is fixed with a vertical plate 17.
[0030] More specifically, the user can first insert the plug block 3 into the plug hole 2, and then connect the multiple plate bodies 1 through the countersunk screws 6 to support railway tracks of different lengths, and then guide the concrete into the through hole 7 through the pouring hole 9. At this time, the concrete in the through hole 7 will flow inside the multiple plate bodies 1 through the guide tube 8. When the concrete solidifies, the connection strength between the plate bodies 1 can be further enhanced.
[0031] See also Figure 1 and Figure 2 As an implementation method for installing the plate body 1 and the backfill layer 18: the backfill layer 18 is provided on the lower end surfaces of the two plate bodies 1, and limit blocks 19 are fixedly provided at the front and rear ends of the plate body 1, and the lower end surfaces of the limit blocks 19 are fixedly provided with limit columns 20, and the limit columns 20 are deeply buried in the backfill layer 18, and the front and rear end surfaces of the plate body 1 and the middle position are fixedly provided with external plates 21, and the upper end surfaces of the external plates 21 are opened with circular holes 22, and the inside of the circular holes 22 are slidably provided with grounding cones 23, and the upper ends of the grounding cones 23 pass through the circular holes 22 and are fixed with downward pressing blocks 24.

[0033] Please refer to Figure 2 As a further implementation method for enhancing the gripping ability of the grounding cone 23 , a pawl 25 is fixedly provided on the outer wall of the grounding cone 23 and at the lower end. The pawl 25 is arranged to be inclined upward and is deeply buried in the backfill layer 18 .
[0034] Specifically, the pawl 25 can be provided to increase the ground gripping ability of the ground cone 23 and prevent it from falling out.
[0035] To sum up, when the overall device is in use: when the user needs to connect multiple plate bodies 1, the plug-in block 3 on the plate body 1 can be first inserted into the plug-in hole 2 on another plate body 1, and then the countersunk screw 6 can be screwed into the connection hole 4 and the mounting hole 5 for fixing, and then the concrete is filled into the through hole 7 through the pouring hole 9. At this time, the concrete in the through hole 7 will flow through the guide tube 8 inside the multiple plate bodies 1. When the concrete solidifies, the connection strength between the plate bodies 1 can be further enhanced. Finally, the external threaded column 13 is screwed into the internal threaded hole 11 through the vertical plate 17 to make the first A conical surface 10 enters into the interior of the second conical surface 12, and then seals the pouring hole 9 to prevent external dust or rainwater from entering, thereby increasing the service life of the plate body 1. When it is necessary to fix the plate body 1 and the backfill layer 18, downward pressure can be applied to the lower pressing block 24 to allow the grounding cone 23 and the ratchet 25 to enter into the backfill layer 18, thereby making the plate body 1 and the backfill layer 18 more firmly installed to prevent displacement problems in the later stage. In addition, by setting the limit block 19 and the limit column 20, the friction between the plate body 1 and the backfill layer 18 can be increased to prevent the train from shaking when traveling on the upper end of the plate body 1.
[0036] When the user needs to connect multiple boards 1, the user can first insert the plug-in block 3 on the board 1 into the plug-in hole 2 on another board 1, and then screw the countersunk screw 6 into the connection hole 4 and the mounting hole 5 to fix it.
[0037] When pouring is required, concrete can be filled into the through hole 7 through the pouring hole 9. At this time, the concrete in the through hole 7 will flow inside the multiple plate bodies 1 through the guide tube 8. After the concrete solidifies, the connection strength between the plate bodies 1 can be further enhanced.
[0038] When the plate body 1 needs to be fixed, downward pressure can be applied to the pressing block 24 to allow the grounding cone 23 and the ratchet 25 to enter the backfill layer 18, thereby making the plate body 1 and the backfill layer 18 more firmly installed to prevent displacement problems in the later stage. In addition, by setting the limit block 19 and the limit column 20, the friction between the plate body 1 and the backfill layer 18 can be increased to prevent the train from shaking when running on the upper end of the plate body 1.
