[0002] During civil construction, steel plates are often laid on temporary roads to form construction access roads. Since the weight and vibration of construction vehicles are often large, it is easy for the edge of the steel plate to sink into the ground when the vehicle drives over it, and squeeze the ground to cause the ground to sink or flow laterally. In particular, when the wheels drive the steel plate to vibrate, the soil in the ground can be loosened and flow laterally, which can lead to insufficient bearing force and sinking of the edge of the steel plate.
[0003] At present, in order to improve the stability of the use of the sidewalk, gravel is often arranged at the bottom of the steel plate to increase the bearing capacity of the stratum and reduce the direct impact of the steel plate on the stratum. The applicant found that when the wheels pass over the edge of the steel plate, they will still transmit greater stress and vibration to the stratum, and the gravel is also prone to sinking. Some of the gravel will also flow from the edge of the steel plate to the upper side of the steel plate.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0027] In the present utility model, if Figure 1-3 As shown, a steel plate walkway vibration reduction and isolation composite supporting device is provided, which is arranged between two adjacent steel plates 3, including: a supporting plate, including a supporting plate body 1, and a vibration isolation layer arranged on the top surface and / or bottom surface of the supporting plate body 1; a connecting rope 2, one end of which is connected to the middle section of the top surface of the supporting plate and the other end is connected to the steel plate 3, and the connecting rope 2 is arranged in this way.
[0028] When installing the supporting device of the utility model, after preliminary leveling of the road surface steel plate 3 paving area, the supporting plate is placed at the edge positions of two adjacent steel plates 3, and the edge of the steel plate 3 is placed at the middle position of the supporting plate, and then the supporting plate and the steel plate 3 are connected together through the connecting rope 2. During the use of the walkway, the vibration generated by the edge of the steel plate 3 is first transmitted to the supporting plate. Since the supporting plate is provided with a vibration isolation layer, the vibration transmitted by the supporting plate to the stratum is weakened, thereby reducing the loose damage of the vibration to the stratum. When the wheel passes over the edge of the steel plate 3, the load of the edge of the steel plate 3 is transmitted to the supporting plate, and the supporting plate is then transmitted downward to the stratum. Since the two edges of the supporting plate are respectively located on the lower side of the two steel plates 3, the horizontal and upward paths of the gravel and soil in the stratum are suppressed. The vertical load generated by the edge of the steel plate 3 can also be dispersed by the supporting plate, further making the stratum at the edge of the steel plate 3 The force is balanced, further reducing the lateral flow and sinking of the stratum at the edge of the steel plate 3 under a large load, and further maintaining the stability of the stratum. In addition, the utility model can make the position of the steel plate 3 and the supporting plate relatively stable by setting a connecting rope 2 to prevent the steel plate 3 and the supporting plate from being misaligned.
[0029] In a preferred embodiment, for the structure of the utility model, a further optimized setting is that a fixing hole is opened at the end of the steel plate 3 near the edge, and the supporting device also includes a fixing rod 4, the fixing rod 4 includes a rod body 401, a ring body 402 connected to the bottom of the rod body, and a cap body 403 connected to the top of the rod body 401, the ring body 402 and the rod body 401 can pass through the fixing hole, and the cap body 403 can abut against the top surface of the steel plate 3 to limit the position; one end of the connecting rope 2 is connected to the ring body 402.
[0030] As shown in the figure, when processing the steel plate 3, it is only necessary to punch a hole in the steel plate 3. When installing the steel plate 3, the connecting rope 2, the ring body 402, and the rod body 401 can be passed through the steel plate 3, so that the cap body 403 abuts against the top surface of the steel plate 3, and then the lower end of the connecting rope 2 is fixed to the supporting plate. In order to maintain the stability of the position of the fixing rod 4 on the steel plate 3, it is preferred to spot weld the cap body 403 and the steel plate 3. For the structure of the fixing rod 4, it is preferred to use a nut welded at the bottom of the bolt.
[0031] In a preferred embodiment, for the structure of the utility model, a further optimized setting is that the top surface of the support plate body 1 is provided with an upper channel steel 5 extending along the transverse direction of the steel plate 3, and the top surface of the support plate body 1 is provided with a vibration isolation layer outside the upper channel steel 5, the height of the vibration isolation layer is higher than the upper channel steel 5, and the vibration isolation layer is connected to the side wall of the upper channel steel 5.
[0032] As shown in the figure, by setting up multiple upper channel steels 5, the vibration isolation layer can be constrained in the lateral direction. The upper channel steels 5 can also play a role in structural reinforcement of the support plate body 1, so as to improve the structural strength of the support plate when the support plate disperses the load pressure on the edge of the steel plate 3, and further improve the uniformity of the load distribution of the support plate body.
[0033] In the illustrated embodiment, a further optimization arrangement of the utility model is that the vibration isolation layer on the top surface of the support plate body 1 is provided with an avoidance groove 6 in the middle section of the support plate body 1; a connecting rod 7 is welded to the side wall of the upper channel steel 5, and a locking buckle 8 that can be connected to the connecting rod 7 is provided at one end of the connecting rope 2 away from the fixing ring 4, and the connecting rope 2 passes through the avoidance groove 6.
[0034] As shown in the figure, after the edge of the steel plate 3 is placed on the supporting plate, the steel plate 3 can be lifted, the connecting rope 2 is stretched at one end of the lock 8 at the position of the connecting rod 7 and connected to the connecting rod 7 through the lock 8, and then the steel plate 3 is put down. By setting the avoidance groove 6, the compression of the steel plate 3 on the connecting rope 2 can be reduced to increase the service life of the connecting rope 2. Preferably, the connecting rope 2 can be a steel strand connecting rope 2.
[0035] In the illustrated embodiment, a further optimized configuration of the utility model is that the side wall of the upper channel steel 5 is provided with a fixing hole 9, and the supporting device includes a fixing nail 10, and the fixing nail 10 is nailed into the vibration isolation layer through the fixing hole 9.

[0037] In the illustrated embodiment, a further optimized setting of the utility model is that the vibration isolation layer includes at least two wooden boards 11, and the two wooden boards 11 are nailed or bonded. Preferably, two layers of waste bamboo and wood templates can be used to form the wooden board 11 structure of the vibration isolation layer to achieve the effect of waste utilization.

As shown in the figure, by providing the upper wooden strips 13, the steel plate 3 can be supported at the position of the upper channel steel 5, and the side wall of the upper channel steel 5 can also be supported by the upper wooden strips 13 to prevent the side wall of the upper channel steel 5 from deforming.

By arranging the lower channel steel 14, the structure of the supporting plate can be further strengthened, and the lower wooden strip 15 can be fixed and constrained. By inserting the lower wooden strip 15 and the lower channel steel 14 into the stratum, the supporting plate can be prevented from moving laterally, so as to further improve the supporting stability of the supporting device.
[0040] In the illustrated embodiment, a further optimized configuration of the present invention is that the lower wooden strip 15 is bonded to the lower channel steel 14 .
