[0023] Example
[0024] See also Figure 1-Figure 4As shown, this embodiment provides a device for dispersing heavy vehicle loads to ensure safe operation of a bridge, including an installation component 10, the installation component 10 includes a bridge body 11, a paving surface 12 is provided on the top of the bridge body 11, a buffer component 20 is fixedly connected to the top of the paving surface 12, a driving steel plate 30 is provided on the top of the buffer component 20, the buffer component 20 is used to absorb the energy generated by vehicle braking, discharge the accumulated water on the top of the paving surface 12 through the driving steel plate 30, and at the same time avoid the driving steel plate 30 itself from being too heavy, thereby increasing the load-bearing burden of the bridge body 11.
[0025] Working principle: When the device for dispersing heavy vehicle loads to ensure safe bridge operation is used, the buffer assembly 20 provided by the utility model absorbs the energy generated by vehicle braking, and the accumulated water on the top of the pavement surface 12 is discharged through the driving steel plate 30, while preventing the driving steel plate 30 from being too heavy, thereby increasing the load-bearing burden of the bridge body 11.
[0026] In order to absorb the energy generated by vehicle braking, the buffer assembly 20 includes a plurality of rubber gaskets 21 arranged side by side and fixedly connected to the top of the pavement surface 12. The spacing between the plurality of rubber gaskets 21 is 1 meter. The top of the rubber gasket 21 is provided with a plurality of bolt holes 22. The cross section of the rubber gasket 21 is a trapezoid with a small top and a large bottom. The rubber gasket 21 adopts a trapezoidal structure design, with a wider bottom and a narrower top. This design can effectively disperse the load transmitted from the driving steel plate 30 to the wider area at the bottom, thereby reducing the pressure per unit area.
[0027] Considering the need to drain the accumulated water on the top of the pavement surface 12 and to prevent the driving steel plate 30 from being too heavy, a plurality of grid holes are provided on the top of the driving steel plate 30; the grid-type driving steel plate 30 has a large number of grid holes, forming a grid-like structure, so that the pressure is not concentrated on a single point or area, but is dispersed over the entire surface of the driving steel plate 30. This design of large-area load dispersion can effectively reduce the pressure on a single point or area.
[0028] In order to facilitate the connection between the rubber gasket 21 and the driving steel plate 30, bolts are provided at positions corresponding to the bolt holes 22 at the bottom of the driving steel plate 30, and the driving steel plate 30 is fixedly connected to the rubber gasket 21 through the bolts and the bolt holes 22; during installation, it is only necessary to align the bolts of the driving steel plate 30 with the bolt holes 22 on the rubber gasket 21, and tighten the bolts to fix the driving steel plate 30 and the rubber gasket 21, thereby absorbing the energy generated by the braking of a heavy vehicle when it passes through the bridge deck.
[0029] The device for dispersing heavy vehicle loads and ensuring safe operation of bridges provided in the utility model absorbs the energy generated by vehicle braking through the buffer assembly 20 provided during specific use. Specifically, the cross section of the rubber gasket 21 is a trapezoid with a small top and a large bottom; the rubber gasket 21 adopts a trapezoidal structure design, with a wider bottom and a narrower top. This design can effectively disperse the load transmitted from the driving steel plate 30 to the wider area at the bottom, thereby reducing the pressure per unit area; the accumulated water on the top of the pavement surface 12 is discharged through the driving steel plate 30, while avoiding the excessive weight of the driving steel plate 30 itself, thereby increasing the load-bearing burden of the bridge body 11. Specifically, the grid-type driving steel plate 30 has a large number of grid holes, forming a grid-like structure, so that the pressure will not be concentrated on a single point or area, but dispersed to the entire surface of the driving steel plate 30. This design of dispersing loads over a large area can effectively reduce the pressure on a single point or area.
