In addition, traditional expansion joints may experience wear and deformation after long-term dynamic loads, which increases the maintenance difficulty and life cycle cost of bridges.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a self-stabilizing and quick-installation bridge expansion joint, comprising:

[0008] The support unit includes a bridge body and a grouting groove hollowed out inside the bridge body, wherein an insertion groove is hollowed out inside the bridge body.

[0009] The insertion and installation unit includes an insertion plate inserted into an insertion slot and an upper connecting plate fixedly connected to one side of the insertion plate.

[0029] Reference Figure 1 - Figure 4 This invention provides a self-stabilizing and quick-installation bridge expansion joint, comprising a support unit 100 and a plug-in installation unit 200.

[0030] The support unit 100 includes a bridge body 101 and a grouting groove 103 hollowed out in the bridge body 101. An insertion groove 104 is hollowed out in the bridge body 101. A threaded groove 102 is hollowed out on the upper surface of the bridge body 101. An interlocking block 105 is fixedly connected in the grouting groove 103. The interlocking block is made of ultra-high performance concrete. There are two sets of bridge bodies 101, and both sets of bridge bodies 101 are symmetrical about the upper connecting plate 202 and the lower connecting plate 208.

[0031] The insertion and installation unit 200 includes an insertion plate 201 inserted into an insertion slot 104 and an upper connecting plate 202 fixedly connected to one side of the insertion plate 201. A lower connecting plate 208 is slidably connected to the lower surface of the upper connecting plate 202. A sliding groove 203 is hollowed out in the upper connecting plate 202. A limit plate 207 is fixedly connected in the sliding groove 203. An auxiliary T-shaped rod 206 is engaged with the upper surface of the lower connecting plate 208. A moving groove 209 is hollowed out on the upper surface of the lower connecting plate 208. A first spring 210 is fixedly connected in the moving groove 209. A connecting block 213 is fixedly connected to one end of the first spring 210. The upper surface of the connecting block 213 is fixedly connected to the lower surface of the upper connecting plate 202.

[0032] A fixing bolt 204 is threaded into the threaded groove 102. The insertion plate 201 is fixedly connected to the bridge body 101 by the fixing bolt 204. There are several T-shaped rods 206, which are evenly distributed on the upper surface of the lower connecting plate 208. The interlocking block 105 has a hollowed-out expansion groove 215. A second spring 212 is fixedly connected to one side of the expansion groove 215. A waterstop plate 211 is fixedly connected to the other end of the second spring 212. A fixing frame 217 is fixedly connected to the upper surface of the waterstop plate 211. A third spring 216 is fixedly connected inside the fixing frame 217. A support plate 218 is fixedly connected to the other end of the third spring 216. The upper surface of the 8 is fixedly connected to the lower connecting plate 208. The side of the fitting block 105 is fixedly connected to the rubber telescopic plate 219. During the pouring process, the fitting block 105 needs to reserve a telescopic groove 215 inside, and use the reserved telescopic groove 215 to allow the waterstop plate 211 to slide in it. The inner surface of the threaded groove 102 is hollowed out with a drainage groove 205. The lower surface of the fitting block 105 is fixedly connected to the inclined insertion block 214.

The inclined insertion block 214 is snapped into the bridge body 101.

[0033] When the equipment is working normally, the bridge body 101 will expand and contract when the bridge is affected by external factors such as temperature changes and traffic loads. The self-stabilizing quick-installation bridge expansion device of this utility model transmits the deformation of the bridge body 101 to the insertion installation unit 200 through the insertion connection of the insertion plate 201 and the insertion groove 104. The upper connecting plate 202 and the lower connecting plate 208 achieve relative sliding through the sliding groove 203 and the limiting plate 207, thereby allowing the bridge body 101 to expand and contract freely in the longitudinal direction.

[0034] Meanwhile, the elastic elements such as the first spring 210, the second spring 212 and the third spring 216 play a role in buffering and automatic adjustment in the device. When the bridge body 101 undergoes expansion and contraction deformation, these springs can absorb some of the deformation energy and reduce the impact load on the device. In addition, the insertion plate 201 is fixedly connected to the bridge body 101 by the fixing bolt 204, which ensures the stability of the device during long-term use.

[0035] In terms of waterproofing, the expansion groove 215 and waterstop 211 in the interlocking block 105 form a multi-layer waterproof barrier, effectively preventing water from seeping into the bridge interior. The rubber expansion plate 219 further enhances the waterproof performance of the device. The design of the drainage groove 205 allows the water inside the device to be discharged in time, avoiding corrosion and damage caused by water accumulation.
