[0022] Embodiment 1

[0023] like Figure 1 As shown:

[0024] A connection structure of a bridge expansion joint comprises a bridge body 1.

[0025] In this embodiment: the existing {public announcement number}: CN207244443U discloses the connection structure of the bridge expansion joint, and this patent discloses a waterstop. The bridge waterstop 8 in the present application document adopts the same technical means in this prior art. This technical means will not be described here one by one. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the waterstop of the device will age after long-term use, so it needs to be replaced, and the device will have a certain resistance to the replacement of the waterstop due to its complex structure, thereby affecting the normal replacement process". In terms of combined use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve the above problems, connecting plates 2 and side plates 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In combination with the above contents: it also includes a connecting plate 2, a side plate 3, a connecting frame 4, a lifting plate 5, a positioning hole 6, a movable frame 7 and a bridge waterstop 8 arranged on one side of the bridge body 1, the surface of the bridge body 1 and the surface of the connecting plate 2 are fitted and connected, and one side of the connecting plate 2 is also fixedly installed with a side plate 3, and the surface of the side plate 3 and the surface of the connecting frame 4 are slidingly connected, and one side of the connecting frame 4 is also fixedly installed with a lifting plate 5 that is slidingly connected to the surface of the side plate 3, and a positioning hole 6 is opened on the surface of the lifting plate 5, and one side of the connecting frame 4 is also rotatably connected to one end of the movable frame 7, and the surface of the movable frame 7 is also fitted and connected to the surface of the bridge waterstop 8.

[0029] In this embodiment: when it is necessary to replace the bridge waterstop 8 set on the bridge body 1, the two adjacent connecting frames 4 can be lifted from the side panels 3. At this time, the connecting frame 4 will drive the lifting plate 5 and the movable frame 7 to rise along the side panels 3 at the same time. At this time, the connection point of the lifting plate 5 and the movable frame 7 is located in the side panels 3. As the connecting frame 4 is gradually lifted, the movable frame 7 and the bridge waterstop 8 are gradually higher than the surface of the bridge body 1. At this time, the connection point of the connecting frame 4 and the movable frame 7 will also rise from the side panels 3, and the positioning hole 6 will also gradually rise above the surface of the side panels 3. At this time, the connecting frame 4 and the lifting plate 5 can be lifted through the positioning hole 6 by a metal lever The heights of the lifting plate 5 and the movable frame 7 are fixed, and without the restriction of the side plate 3, the movable frame 7 can rotate with the connecting frame 4. When the movable frame 7 rotates to a position away from the bridge waterstop 8, the movable frame 7 will gradually separate from the bridge waterstop 8. At this time, the aged bridge waterstop 8 can be removed from the movable frame 7, and the new bridge waterstop 8 can be installed in the movable frame 7. Subsequently, the metal lever connected to the positioning hole 6 is removed from the positioning hole 6, and the connecting frame 4, the lifting plate 5 and the movable frame 7 are returned to the side plate 3 again, and the replacement of the bridge waterstop 8 is completed.

[0030] Going further:

[0031] In an optional embodiment, the connecting plate 2 and the side plates 3 are symmetrically arranged on both sides of the surface of the bridge body 1 .

[0032] In this embodiment: the connecting plates 2 and side plates 3 symmetrically arranged on both sides of the bridge body 1 can form a connection at the end of the bridge body 1, and can be connected between the two through the bridge waterstop 8, which can effectively improve the stability of the bridge body 1.

[0033] Going further:

[0034] In an optional embodiment, rectangular grooves are formed at equal intervals on the surface of the connecting frame 4 .

[0035] In this embodiment, the grooves formed on the surface of the connecting frame 4 can form a sufficiently large contact surface between the lifting plate 5 and the movable frame 7 and the connecting frame 4, so that the lifting plate 5 and the movable frame 7 have higher stability.

[0036] Going further:

[0037] In an optional embodiment, the width of the lifting plate 5 is the same as the width of the movable frame 7 .

[0038] In this embodiment: the movable frame 7 having the same width as the lifting plate 5 can enable the two to form a stable fit inside the bridge body 1, and can play a good connection and expansion and contraction role for the bridge body 1 under the stability of the connecting frame 4 and the side plate 3.

[0039] Going further:

[0040] In an optional embodiment, the positioning holes 6 are circular in shape, and the positioning holes 6 are symmetrically opened on both sides of the surface of the lifting plate 5 .

[0041] In this embodiment: the positioning holes 6 symmetrically opened on both sides of the surface of the lifting plate 5 enable the height of the lifting plate 5 to be fixed through the positioning holes 6 after being lifted, and then the movable frame 7 can be rotated between the connecting frame 4, so that the bridge waterstop 8 can be easily replaced.

[0042] Going further:

[0043] In an optional embodiment, a groove matching the bridge waterstop 8 is formed on the surface of the movable frame 7 .

[0044] In this embodiment: the groove opened on the surface of the movable frame 7 can provide the bridge waterstop 8 with a stable installation space, so that the bridge waterstop 8 can work normally, and under the action of the two movable frames 7, the stability of the bridge waterstop 8 can be effectively improved.

[0045] The working principle and use process of the utility model are as follows: when it is necessary to replace the bridge waterstop 8 set on the bridge body 1, the two adjacent connecting frames 4 can be lifted from the side panels 3. At this time, the connecting frames 4 will drive the lifting plates 5 and the movable frames 7 to rise along the side panels 3 at the same time. At this time, the connection points of the lifting plates 5 and the movable frames 7 are located in the side panels 3. As the connecting frames 4 are gradually lifted, the movable frames 7 and the bridge waterstop 8 are gradually higher than the surface of the bridge body 1. At this time, the connection points of the connecting frames 4 and the movable frames 7 will also rise from the side panels 3, and the positioning holes 6 will also gradually rise above the surface of the side panels 3. At this time, the connecting frames 4 can be passed through the positioning holes 6 through the metal levers The heights of the connecting frame 4, the lifting plate 5 and the movable frame 7 are fixed, and without the restriction of the side plate 3, the movable frame 7 can rotate with the connecting frame 4. When the movable frame 7 rotates to a position away from the bridge waterstop 8, the movable frame 7 will gradually separate from the bridge waterstop 8. At this time, the aged bridge waterstop 8 can be removed from the movable frame 7, and the new bridge waterstop 8 can be installed in the movable frame 7. Subsequently, the metal lever connected to the positioning hole 6 is removed from the positioning hole 6, and the connecting frame 4, the lifting plate 5 and the movable frame 7 are returned to the side plate 3 again, and the replacement of the bridge waterstop 8 is completed.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
