[0035] Among them, the pulling piece 400 connects the bridge 200 and the limiting piece 300, and tightens the bridge 200 and the limiting piece 300 through the tensioned pulling piece 400, which can make the bridge 200 and the limiting piece 300 closely fit on one hand, and on the other hand, the pier 100, the limiting piece 300 and the bridge 200 can remain relatively stable, which can effectively reduce the risk of the bridge 200 sliding off the pier 100, and can significantly improve the anti-seismic safety.

[0038] In an optional embodiment, the pulling pieces 400 can be installed on both sides of one bridge 200, and the two pulling pieces 400 are one-to-one connected to the two limiting pieces 300 installed on the bridge pier 100. On the one hand, the two pulling pieces 400 can pull the bridge 200 to prevent the bridge 200 from falling off the bridge pier 100. On the other hand, the two pulling pieces 400 one-to-one pull the two limiting pieces 300, so that the bridge 200 is constrained between the two limiting pieces 300, thereby improving the stability of the bridge 200 relative to the bridge pier 100.

[0039] As shown in Figure 1 and Figure 3 , the pulling piece 400 includes a first connecting piece 410, an anchor chain 420, and a second connecting piece 430.

Wherein, the joint 431 is hinged with the hinged member 432, the anchor chain 420 can swing relative to the hinged member 432 along with the joint 431, and the tension of the anchor chain 420 can make the force of the second connecting member 430 on the limiting member 300 produce a component force pressing the bridge 200, which is beneficial to ensure the reliability of the limiting action of the limiting member 300 on the bridge 200.

[0042] Further, the second connecting member 430 further comprises a plate member 434 and a threaded fastener 435; the plate member 434 is connected with the limiting member 300, the connecting rod 433 passes through the plate member 434, and the connecting rod 433 cooperates with the threaded fastener 435, and the threaded fastener 435 abuts against the plate member 434. By screwing the threaded fastener 435, the sliding of the connecting rod 433 along the axial direction relative to the plate member 434 can be adjusted, and then the tension of the anchor chain 420 can be adjusted.

[0043] In optional embodiments, the plate member 434 can be pre-buried or welded in the limiting member 300.

[0044] In the present embodiment, the limiting member 300 is provided with a mounting groove 301, the plate member 434 is inserted into the mounting groove 301, and the plate member 434 is fixed by pouring concrete in the mounting groove 301, which is convenient for construction and can ensure the stability of the plate member 434.

[0045] As shown in Figure 1 , Figure 2 and Figure 5 , the limiting member 300 comprises a limiting base 310 and a pushing block 320; the limiting base 310 is installed on the top of the pier 100, and the pushing block 320 is installed on the limiting base 310 and abuts against the side surface of the bridge 200.

[0046] Further, from one end of the connecting bridge 200 to one end of the connecting limiting member 300, the pulling member 400 is inclined away from the bridge 200.

[0047] Referring to Figure 2 , two pulling members 400 pull the same limiting member 300 and make the limiting member 300 abut against the side surface of the two bridges 200, and similarly, the other two pulling members 400 pull the other limiting member 300 and make it abut against the side surface of the two bridges 200, so that the two bridges 200 are stably limited on the top of the pier 100.

[0048] As shown in Figure 1 , Figure 2 ,Figure 4 and Figure 5 As shown in the figure, the limiting member 300 further comprises an adjusting rod 330, a movable block 340 and an elastic member 350; the movable block 340 is slidingly fitted to the limiting base 310 along the extending direction of the bridge 200, and the movable block 340 is connected to the pushing block 320; the elastic member 350 is installed between the movable block 340 and the limiting base 310; the adjusting rod 330 is threadedly fitted to the limiting base 310, and the adjusting rod 330 abuts against the movable block 340 along the sliding direction of the movable block 340.

[0049] When the adjusting rod 330 is screwed, the adjusting rod 330 can push the movable block 340 in the axial direction and drive the elastic member 350 to elastically deform; the movable block 340 sliding relative to the limiting base 310 can drive the pushing block 320 to move, thereby adjusting the position of the pushing block 320 relative to the bridge 200 to change the position of the pushing block 320 abutting against the side surface of the bridge 200.

[0050] It should be noted that the pushing block 320 can be made of hard rubber, which is pressed against the side surface of the bridge 200, and the contact position of the pushing block 320 with the bridge 200 can be adjusted, which can increase the position adjustment range of the pushing block 320 for the pushing and limiting action on the bridge 200.

[0055] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
