Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated track plates, in particular to a coupling device of prefabricated track plates. Background Art

[0002] With the rapid development of the rail transit industry, prefabricated track slabs are increasingly being used due to their significant advantages such as rapid on-site construction and excellent prefabrication quality. When prefabricated track slabs are laid along the rail transit line, adjacent prefabricated track slabs need to be connected into a whole, especially the shear force needs to be transferred between the prefabricated track slabs to ensure the smoothness of the line and the stability of the structure.

[0003] At present, the most common method of connecting prefabricated track plates is to use shear hinges, which mainly include top-mounted shear hinges and center-mounted shear hinges. The top-mounted shear hinge is installed at the adjacent position on the upper surface of the prefabricated track plate, while the center-mounted shear hinge is installed at the adjacent position in the middle of the prefabricated track plate. However, whether it is a top-mounted shear hinge or a center-mounted shear hinge, the installation and construction are both relatively troublesome. For the top-mounted shear hinge, its main body is installed on the surface of the prefabricated track plate. Although it is convenient to replace, it undoubtedly occupies space. For the center-mounted shear hinge, when it breaks due to large local force, it is difficult to replace or repair the shear hinge. Summary of the invention

[0004] The purpose of the utility model is to provide a connection device for prefabricated track plates in accordance with the above-mentioned deficiencies of the prior art, by adjusting the plate end thickness of the prefabricated track plates to form a concave-convex shape to connect the steel plates, and by connecting the connecting steel plates to the prefabricated track plates on both sides respectively, so that the prefabricated track plates on both sides are connected into an integral structure through the connecting steel plates, thereby realizing the transmission of shear force.

[0005] The purpose of this utility model is achieved by the following technical solutions:

[0006] A connection device for prefabricated track plates, comprising two prefabricated track plates to be connected, characterized in that: a first groove is provided at the top of a connection side surface of one of the prefabricated track plates, a second groove is provided at the bottom position of a connection side surface of the other prefabricated track plate, a connection steel plate matching the shape and size of the first groove and the second groove is provided between the connection sides of the two prefabricated track plates, a part of the connection steel plate is inserted into the first groove, and another part of the connection steel plate is inserted into the second groove at the same time, and the connection steel plates are respectively fixedly connected to the two prefabricated track plates.

[0007] The connecting steel plate is fixedly connected to the prefabricated track plate by connecting bolts, and the connecting bolts are located at the position of the first groove of one prefabricated track plate or the position of the second groove of another prefabricated track plate.

[0008] A plurality of the connecting bolts are evenly spaced and arranged along the width direction of the prefabricated track slab.

[0009] An embedded sleeve matched with the connecting bolt is embedded in the plate body of the prefabricated track plate at the position of the first groove or the second groove.

[0010] A rubber material buffer layer is arranged between the connecting steel plate and the connecting side surface of the prefabricated track plate.

[0011] The utility model has the advantages of sufficient strength, convenient for the implementation and disassembly of the prefabricated track plate; using conventional materials, easy for implementation; simple and reasonable structure, suitable for the prefabrication of the track plate, and suitable for promotion.

[0014] 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 technicians in the same industry:

[0015] like Figure 1-2 As shown, the marks 1-6 in the figure respectively represent: a first prefabricated track plate 1, a second prefabricated track plate 2, a connecting bolt 3, a connecting steel plate 4, an embedded sleeve 5, and a rubber material buffer layer 6.

[0016] Example: Figure 1 to Figure 2 As shown, the coupling device of the prefabricated track plate in this embodiment is used to couple the first prefabricated track plate 1 and the second prefabricated track plate 2 to form an integral structure. In this embodiment, the first prefabricated track plate 1 and the second prefabricated track plate 2 are two adjacent prefabricated track plates arranged along the line direction, and the remaining prefabricated track plates on the line can also be connected in pairs using the coupling device in this embodiment, so that the prefabricated track plates on the entire line are uniformly connected to form an integral structure.

[0017] Specifically, if Figure 2As shown, a first groove is provided at the top position of the connecting side surface of the first prefabricated track plate 1 (which cannot be reflected due to the snap-in position of the connecting steel plate 4), and a second groove is provided at the bottom position of the connecting side surface of the second prefabricated track plate 2 (which cannot be reflected due to the snap-in position of the connecting steel plate 4). Both the first groove and the second groove are grooves arranged along the width direction of the plate body of the prefabricated track plate.

[0018] A connecting steel plate 4 is provided between the connecting sides of the first prefabricated track plate 1 and the second prefabricated track plate 2, and the connecting steel plate 4 matches the first groove and the second groove respectively, so that a part of the connecting steel plate 4 is inserted into the first groove of the first prefabricated track plate 1, and another part is inserted into the second groove of the second prefabricated track plate 2, so that parts on both sides of the connecting steel plate 4 form partial overlaps with the first prefabricated track plate 1 and the second prefabricated track plate 2 respectively.

[0019] An embedded sleeve 5 is provided at the position where the grooves are respectively provided on the first prefabricated track plate 1 and the second prefabricated track plate 2; by screwing the connecting bolt 4 into the embedded sleeve 5, the connecting steel plate 4 can be respectively connected and fixed to the first prefabricated track plate 1 and the second prefabricated track plate 2 to form a whole, thereby making the first prefabricated track plate 1 and the second prefabricated track plate 2 connected through the connecting steel plate 4 therebetween to form an integral structure and realize the transmission of shear force.

[0020] like Figure 2 As shown, a rubber material buffer layer 6 is provided between the two sides of the connecting steel plate 4 and the connecting side surfaces of the first prefabricated track plate 1 or the second prefabricated track plate 2 to ensure that the force along the line direction can be effectively buffered by the rubber material buffer layer 6 .

[0021] In the specific implementation of this embodiment: Figure 1 As shown, a plurality of connecting bolts 3 are evenly spaced in the width direction of the first prefabricated track plate 1 and the second prefabricated track plate 2, so that the first prefabricated track plate 1 and the second prefabricated track plate 2 can be connected into a stable integral structure in the width direction of the plate.

[0022] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model 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 utility model without departing from the scope of the claims, so they are not described one by one here.
