When assembling the two sidewalk panels, the extended threaded rod is inserted into the inner wall of the cylinder of the adjacent sidewalk panel body, connecting the two adjacent sidewalk panels. This helps to prevent gaps between the panels and the panels from separating from the road surface. However, when vehicles pass on the road adjacent to the sidewalk, the gaps between the prefabricated blocks will generate noise.

[0004] Therefore, we provide a prefabricated concrete multifunctional sidewalk to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a prefabricated concrete multifunctional sidewalk to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a prefabricated concrete multifunctional sidewalk, comprising a sidewalk body and a working mechanism, wherein a shell is threadedly connected to the surface of the sidewalk body, and the working mechanism is installed inside the sidewalk body;

[0007] The working mechanism includes a connecting component, a fixing component, a shock-absorbing component and a plug-in component.

[0010] Preferably, the shock absorbing assembly includes a support pad and a lead column, the support pad is installed on one side of the steel plate, and the lead column is installed inside the support pad.

[0011] Preferably, the plug-in assembly includes a slide groove and a slide rod, the slide groove is provided on the outer side of the walkway body, and the slide rod is slidably connected to the inner side of the slide groove.

[0012] Preferably, the support pad is made of rubber, and the support pad is adhesively connected to the steel plate.

[0015] 1. Through the setting of the working mechanism, the connecting plate is fixed by fixing bolts and tightened by nuts, so that the steel plate and the connecting plate can be connected, and then the support pad is connected to the main body of the sidewalk. When subjected to vibration, the rubber support pad layer will deform due to its elasticity, thereby reducing the impact caused by the seismic wave directly transmitted to the main body of the sidewalk. The presence of the lead core increases the damping ratio of the support. When the seismic force exceeds a certain threshold, the lead core begins to plastically deform. The plastic deformation process of the lead core is actually an energy dissipation process. It effectively reduces the response of the sidewalk by converting seismic energy into heat energy, thereby improving the stability of the connection between the main bodies of the sidewalk and reducing the generation of noise.

[0016] 2. By setting up the plug-in components, the sliding rods are inserted into the slide grooves, so that the modular sidewalk units can be connected quickly and accurately.

[0027] Furthermore, the fixing assembly 32 includes a nut 321 and a steel plate 322 . The outer side of the fixing bolt 312 is threadedly connected to the nut 321 , and one side of the fixing bolt 312 is fixedly connected to the steel plate 322 . The nut 321 ensures a stable connection between the fixing bolt 312 and the connecting plate 311 .

[0028] Furthermore, the shock absorbing assembly 33 includes a support pad 331 and a lead column 332. The support pad 331 is installed on one side of the steel plate 322, and the lead column 332 is installed inside the support pad 331. The lead column 332 provides additional damping effect to absorb and dissipate vibration energy.

[0029] Furthermore, the plug-in component 34 includes a slide groove 341 and a slide rod 342. The slide groove 341 is provided on the outside of the sidewalk body 1, and the slide rod 342 is slidably connected to the inside of the slide groove 341. The slide rod 342 is inserted into the slide groove 341 to splice the modular sidewalk bodies 1.

[0030] Furthermore, the support pad 331 is made of rubber, and the support pad 331 and the steel plate 322 are adhesively connected. The support pad 331 absorbs vibrations through the rubber and plays a buffering role.

[0031] Example 2

[0032] See also Figure 1 As shown, in comparative example 1, as another embodiment of the present invention, an anti-skid component 4 is installed at the top of the sidewalk body 1. The anti-skid component 4 includes a base 41 and an anti-skid plate 42.

The second step is to fix the connecting plate 311 with the fixing bolt 312 and tighten it with the nut 321. In this way, the steel plate 322 can be connected to the connecting plate 311. Then, the support pad 331 is connected to the sidewalk body 1. When subjected to vibration, the rubber support pad 331 layer will deform due to its elasticity, thereby reducing the impact caused by the seismic wave directly transmitted to the sidewalk body 1. The presence of the lead core increases the damping ratio of the support. When the seismic force exceeds a certain threshold, the lead core begins to plastically deform. The plastic deformation process of the lead core is actually an energy dissipation process. It effectively reduces the response of the sidewalk by converting seismic energy into heat energy, thereby improving the stability of the connection between the sidewalk bodies 1 and reducing the noise generation. In this way, the use process of a prefabricated concrete multifunctional sidewalk is completed.
