Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit technology, and in particular to a side-mounted shear plate and a side-mounted shear plate connection structure. Background Technology
[0002] Steel spring floating slab tracks are currently the most effective vibration reduction measure for subways and are widely used in major subway lines. To improve the overall integrity of the floating slab track, enhance track smoothness, and reduce relative displacement between adjacent slabs, shear hinges or shear plates are introduced at the joints between the floating slabs. Among these, side-mounted shear plates are a relatively common type of shear plate structure.
[0003] However, this structure suffers from poor fatigue resistance. Due to the low stiffness of the floating slab track itself, coupled with factors such as uneven tunnel settlement and repeated train loading, the structure is prone to bolt breakage and shear plate cracking during long-term use. Once these problems occur, they will increase the train load, causing more shear plate fatigue issues, and posing challenges to train operation safety and the lifespan of the floating slab track.
[0004] Therefore, there is an urgent need for a side-mounted shear plate and a side-mounted shear plate connection structure to solve the above problems. Utility Model Content

[0036] like Figures 1-4As shown, this embodiment provides a side-mounted shear plate for connecting floating slabs in rail transit. The side-mounted shear plate includes a main connecting plate 1, a stiffening plate group 2, and multiple bolts 3. The main connecting plate 1 is used to connect two adjacent floating slabs. The main connecting plate 1 includes a first connecting plate 11 and a second connecting plate 12. One end of the first connecting plate 11 and one end of the second connecting plate 12 are fixedly connected, and the first connecting plate 11 and the second connecting plate 12 are set at an angle. The height direction of the first connecting plate 11 and the height direction of the second connecting plate 12 are both parallel to the height direction of the main connecting plate 1 and both are perpendicular to the length direction of the main connecting plate 1. The main connecting plate 1 is configured such that one side faces the floating slab and the other side faces away from the floating slab. The stiffening plate group 2 is fixedly installed on the side of the main connecting plate 1 away from the floating plate. The stiffening plate group 2 includes a first transverse stiffening plate 21, a second transverse stiffening plate 22 and a vertical stiffening plate 23. The first transverse stiffening plate 21 and the second transverse stiffening plate 22 are spaced apart along the height direction of the main connecting plate 1 and both extend along the length direction of the main connecting plate 1. The first connecting plate 11 and the second connecting plate 12 are both fixedly connected to the first transverse stiffening plate 21 and the second transverse stiffening plate 22. The vertical stiffening plate 23 is fixedly installed at the connection between the first connecting plate 11 and the second connecting plate 12 and extends along the joint between the first connecting plate 11 and the second connecting plate 12. The first connecting plate 11 and the second connecting plate 12 are both fixedly connected to the vertical stiffening plate 23.
[0037] The side-mounted shear plate provided in this embodiment provides lateral support to the main connecting plate 1 through first transverse stiffeners 21 and second transverse stiffeners 22 spaced apart along the height direction of the main connecting plate 1, and strengthens the connection between the first connecting plate 11 and the second connecting plate 12 through vertical stiffeners 23 set at the joint of the first connecting plate 11 and the second connecting plate 12, thereby effectively improving the shear stiffness of the side-mounted shear plate and preventing cracking of the side-mounted shear plate during long-term use.
[0038] Furthermore, such as Figure 1 and Figure 3 As shown, the first transverse stiffener 21 is disposed at the top of the main connecting plate 1, and the second transverse stiffener 22 is disposed at the bottom of the main connecting plate 1, so as to further improve the supporting effect of the first transverse stiffener 21 and the second transverse stiffener 22 on the main connecting plate 1.
[0039] Furthermore, such as Figure 1 and Figure 3 As shown, the top end of the vertical stiffener 23 is fixedly connected to the first horizontal stiffener 21, and the bottom end is fixedly connected to the second horizontal stiffener 22, so that the stiffener group 2 forms a whole and improves the overall support effect of the stiffener group 2 on the main connecting plate 1.
[0040] Specifically, in this embodiment, the first transverse stiffener 21 is welded and fixed to the first connecting plate 11, the second transverse stiffener 22 is welded and fixed to the first connecting plate 11, the vertical stiffener 23 is welded and fixed to the first connecting plate 11, the first transverse stiffener 21 is welded and fixed to the second connecting plate 12, the second transverse stiffener 22 is welded and fixed to the second connecting plate 12, and the vertical stiffener 23 is welded and fixed to the second connecting plate 12. The main connecting plate 1, the first transverse stiffener 21, the second transverse stiffener 22, and the vertical stiffener 23 are all made of steel.
[0041] Optionally, such as Figures 1-4 As shown, the side-mounted shear plate in this embodiment also includes multiple bolts 3. Both the first connecting plate 11 and the second connecting plate 12 are provided with connecting holes 13. The bolts 3 are provided in a one-to-one correspondence with the connecting holes 13. The bolts 3 are used to pass through the corresponding connecting holes 13 to connect the main connecting plate 1 and the floating plate.
[0042] Furthermore, such as Figures 1-4 As shown, both the first connecting plate 11 and the second connecting plate 12 are provided with three connecting holes 13, which are arranged in a triangular pattern. The first connecting plate 11 is connected to the floating plate, and the second connecting plate 12 is connected to the floating plate, each by three bolts 3. That is, the first connecting plate 11 is connected to one of the two adjacent floating plates by three bolts arranged in a triangular pattern, and the second connecting plate 12 is connected to the other of the two adjacent floating plates by three bolts arranged in a triangular pattern. This triangular force-bearing structure is more stable and reliable, and avoids the excessive concentration of the three bolts 3, resulting in more even stress distribution on the three bolts 3 and preventing bolt breakage during long-term use.
[0043] like Figure 5 As shown, this embodiment also provides a side-mounted shear plate connection structure, including the side-mounted shear plate described above, and two floating plates, including a first floating plate 100 and a second floating plate 200 (that is, one of the two floating plates is the first floating plate 100 and the other is the second floating plate 200). A first connecting plate 11 is connected to the first floating plate 100, and a second connecting plate 12 is connected to the second floating plate 200.
[0044] Furthermore, both the first floating plate 100 and the second floating plate 200 are provided with embedded sleeves, which are provided with internal threads, and the bolts 3 are threadedly connected to the embedded sleeves. The embedded sleeves are embedded in the floating plates, and the bolts 3 are stably connected to the floating plates by pre-embedding the sleeves in the floating plates.
[0045] Furthermore, such as Figure 5As shown, a first receiving groove 1001 is provided at one end of the first floating plate 100 near the second floating plate 200, and a second receiving groove 2001 is provided at one end of the second floating plate 200 near the first floating plate 100. A first inclined surface 1002 is provided at the bottom of the first receiving groove 1001, and a second inclined surface 2002 is provided at the bottom of the second receiving groove 2001. A first connecting plate 11 is attached to the first inclined surface 1002 on the side facing the first floating plate 100, and a second connecting plate 12 is attached to the second inclined surface 2002 on the side facing the second floating plate 200.
[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
