Description

Technical Field

[0001] The utility model relates to the technical field of pre-supported track plates, in particular to a slot-type prefabricated track plate. Background Art

[0002] Currently, precast track slabs typically have gaps between them, and then bosses are placed between them to limit the position of the slabs on either side, ensuring their accurate positioning. However, this creates a barrier between adjacent slabs, resulting in poor integrity between the slabs. Summary of the Invention

[0003] The purpose of the utility model is to provide a slot-type prefabricated track plate based on the above-mentioned deficiencies of the existing technology, which realizes the rapid connection of the prefabricated track plate by setting a concave-convex structure when the prefabricated track plate is prefabricated, while improving the integrity of the prefabricated track plate.

[0004] The purpose of this utility model is achieved by the following technical solutions:

[0005] A slot-type prefabricated track plate comprises a prefabricated track plate body, characterized in that grooves and protrusions are respectively provided on two side surfaces of the prefabricated track plate body perpendicular to the line direction, and the grooves and protrusions on adjacent side surfaces of adjacent prefabricated track plate bodies match each other, that is, the grooves and protrusions on the side surfaces of the prefabricated track plate body on one side match the protrusions and grooves on the side surfaces of the prefabricated track plate body on the other side, and adjacent prefabricated track plate bodies are connected via the concave-convex structure of the grooves and protrusions.

[0006] An elastic material buffer layer is adhered to the interior of the groove.

[0007] The buffer layer is a rubber buffer layer or a polyurethane buffer layer.

[0008] Two groups of grooves and protrusions are respectively provided on two side surfaces of the prefabricated track plate body perpendicular to the track direction, and the grooves and protrusions are arranged in an alternating manner.

[0009] The utility model has the advantages of simple and reasonable structure, high degree of prefabrication, convenient installation and disassembly, ability to ensure good integrity of multiple prefabricated track plates, and suitability for promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0014] like Figure 1-3 As shown, the marks 1-4 in the figure respectively represent: prefabricated track plate 1, protrusion 2, groove 3, elastic material buffer layer 4.

[0015] Example: Figures 1 to 3 As shown, the slot-type prefabricated track plate in this embodiment includes a prefabricated track plate 1 body, and protrusions 2 and grooves 3 are provided on the two sides of the prefabricated track plate 1 perpendicular to the track direction. Figure 3 As shown, taking one side of the prefabricated track plate 1 as an example, there are two protrusions 2 and two grooves 3 arranged at staggered intervals. From left to right in the horizontal direction of the track, there is one groove 3, one protrusion 2, one groove 3 and one protrusion 2. On the other side of the prefabricated track plate 1, there are grooves 3 and protrusions 2 that match the two protrusions 2 and the two grooves 3 respectively. Figure 3 For example, the other side surface of the prefabricated track plate 1 should be arranged in an arrangement of one protrusion 2, one groove 3, one protrusion 2 and one groove 3.

[0016] During use, the protrusions 2 and grooves 3 provided on adjacent side surfaces of adjacent prefabricated track plates 1 are matched and matched, so that adjacent prefabricated track plates 1 can be plugged in, that is, adjacent prefabricated track plates 1 can be spliced ​​through the concave-convex connection structure between the protrusions 2 and the grooves 3, thereby realizing the connection between the prefabricated track plates 1, thereby improving the integrity between the multiple prefabricated track plates 1.

[0017] In this embodiment, both the protrusions 2 and grooves 3 are prefabricated structures prefabricated on the sides of the prefabricated track slab 1. Their structural dimensions apply only to the sides of the prefabricated track slab 1 (not to the top and bottom surfaces), thereby ensuring the overall structural performance of the prefabricated track slab 1, particularly the flatness of the top surface. Furthermore, the staggered arrangement of adjacent prefabricated track slabs 1 ensures a secure and stable connection after assembly. This further facilitates the prefabrication of the prefabricated track slab 1, avoiding the inconvenience of having only grooves or protrusions on a single side of the prefabricated track slab 1.

[0018] like Figure 2 As shown, a 10 mm thick elastic material buffer layer 4 made of rubber or polyurethane material is adhered in the groove 3, thereby improving the integrity between the prefabricated track plates 1 while achieving buffering between adjacent prefabricated track plates 1, especially avoiding local damage to the local concave-convex structure when the force is transmitted.

[0019] Although the above embodiments have described the concepts and embodiments of the present invention in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, so they are not described here one by one.
