Description

The present invention relates to an overcoming device used for overcoming a step or a gap generated in a road.

For example, at a disaster site or a construction site, if there are steps or gaps that cross the road, a boarding board is placed on these steps or gaps, and the vehicle runs on these steps or gaps to eliminate the steps or gaps. I am trying to pass through.

As a boarding plate of this type, a thick plate-shaped transfer plate formed by sandwiching a plurality of columnar reinforcing members extending in the longitudinal direction between a rectangular upper plate and a lower plate has been conventionally proposed (patented). Reference 1). Since this transfer plate is made of fiber reinforced plastic and is lightweight, it can be transported manually, and even if the work vehicle cannot proceed due to a disaster, it can be quickly transported to the site and installed. There is.

FIG. 8 is a schematic view showing how the conventional transfer board is arranged in a gap of a road. As shown in FIG. 8, the transfer plate 101 is arranged so as to bridge the gap G that crosses the road, and then sandbags 102 and 102 are arranged at both ends to fix the transfer plate 101 and the transfer plate 101. It is possible for vehicles to easily enter by relaxing the steps caused by the thickness of the sandbag.

JP-A-2017-43989

However, in the conventional transfer plate 101, the sandbag 102 that fixes both ends is easily deformed or damaged as the vehicle passes through, and there is a disadvantage that the transfer plate 101 easily moves. At a disaster site or a construction site, a relatively large number of large work vehicles travel, so that the sandbag 102 tends to deteriorate, and the transfer plate 101 easily moves because it frequently receives a relatively large driving force of the wheels. When the transfer plate 101 moves, the transfer plate 101 and the vehicle may fall into the gap G. Further, when the transfer plate 101 is arranged so as to get over the step, if the transfer plate 101 moves, the transfer plate 101 falls on the lower road surface forming the step, and there is a disadvantage that the effect of eliminating the step is lost. .. Further, when the sandbag 102 that fixes the passing plate 101 deteriorates, a step is generated between the passing plate 101 and the road surface, which causes a disadvantage that the riding comfort of the vehicle is deteriorated. In addition, the deterioration of the sandbag 102 causes the internal soil to leak out, which has the disadvantage of deteriorating the surrounding environment.

Therefore, an object of the present invention is to provide an overcoming device that can effectively prevent movement of a vehicle as it travels. Another object of the present invention is to provide an overcoming device that does not deteriorate the surrounding environment even if the use is continued.

Become. Here, since the engaging body connected to the plate-shaped body engages with the gap or the step, even if the vehicle repeatedly travels on the plate-shaped body, the movement of the overcoming device can be effectively prevented. .. Therefore, it is possible to effectively prevent the inconvenience of falling into a gap like a conventional transfer plate and the inconvenience of falling to a side having a low step. Further, since the overcoming device of the present invention does not require a sandbag for fixing, the sandbag deteriorates as the vehicle travels, and the soil does not leak from the sandbag to deteriorate the surrounding environment.

Further, since the position of the engaging body connected to the plate-shaped body can be changed in the traveling direction of the vehicle, the engaging body can be connected to an appropriate position according to the shape of the gap or the step. Therefore, this overcoming device can be used to overcome gaps and steps of various widths and shapes, and can effectively prevent movement. Here, the engaging body may be directly connected to the plate-shaped body, or may be indirectly connected to the plate-shaped body via another member.

The outer surface of the plate-shaped portion of the support main body 10 of the support member 7 is a surface that becomes an end surface of the frame 3 when grounded, and is a surface that faces the slope member 4 connected to the end portion of the frame 3. Since the rubber plate 13 is fixed to this surface, even if the slope member 4 vibrates when the vehicle passes over the slope member 4, the rubber plate 13 causes an impact generated on the slope member 4 and the frame 3. Noise can be effectively suppressed. In addition to the rubber plate 13, another elastic body such as a resin plate may be provided on the outer surface of the plate-shaped portion of the support main body 10.

As described above, in the overcoming device 1 of the present embodiment, the frame 3 is composed of a separable support member 7 and a side angle member 8, the plate-like body 2 is composed of a plurality of divided plates 20, and the slope member 4 is formed. Since the members are separably formed from the frame 3, the members separated from each other are light enough to be transported by human power. Therefore, the constituent members of the overcoming device 1 can be easily carried into a position where heavy machinery and work vehicles cannot enter due to a disaster or the like. Further, each member can be assembled by an operator who is arranged one by one on each floor slab D1 and D2, and no heavy machine or special tool is required. Therefore, even if it is difficult to procure heavy machinery or special tools due to a disaster or the like, the overcoming device 1 can be quickly assembled to restore a road having a gap or a step.

Further, in the overcoming device 1 of the present embodiment, since the two stoppers 9 connected to the frame 3 engage with the end faces of the floor slabs D1 and D2 forming the gap G, even if the vehicle passes through. It is possible to effectively prevent the inconvenience that the overcoming device 1 moves in the traveling direction of the vehicle.

Further, in the overcoming device 1 of the present embodiment, slope members 4 are arranged at both front and rear ends of the plate-shaped body 2, and the slope members 4 guide the vehicle from the road surface onto the plate-shaped body 2, so that sandbags as in the conventional case are used. Is unnecessary. Therefore, it is possible to effectively prevent the inconvenience that the sandbag deteriorates as the vehicle passes and the soil in the sandbag leaks and the surrounding environment deteriorates. In addition, inconveniences caused by sandbags, such as deterioration of vehicle riding comfort due to deformation of sandbags, can be reliably prevented.

In the above embodiment, the overcoming device 1 has the stopper 9 as an engaging body connected to the side angle member 8 of the frame 3, but may be connected to another member. Further, the engaging body may be connected to the plate-shaped body. In short, the engaging body may be installed anywhere as long as it can prevent the plate-shaped body from moving over a gap or a step.

Further, in the above embodiment, the frame 3 of the overcoming device 1 is fixed to the floor slabs D1 and D2 by anchors via the anchor connecting portion 11, but the fixing of the frame 3 by the anchors may be omitted. In this case, the support member 7 does not have to be provided with the anchor connecting portion 11.

Further, the overcoming device 1 of the above embodiment was used to bridge between the floor slab D1 and the floor slab D2 in which the gap G and the step were formed, but was used to bridge between the floor slab and the abutment. You may. Further, the overcoming device 1 may be installed to overcome either the gap or the step.

Further, although the overcoming device 1 of the above embodiment was used at a disaster site caused by an earthquake on an elevated road, it may be used at another disaster site. Further, in addition to the elevated road, the overcoming device 1 can be used when a gap or a step is generated in various bridge roads, embankment roads, and general ground surface roads. Further, the overcoming device 1 may be used at the construction site.

The present invention is not limited to the embodiments described above, and many modifications are possible by those who have ordinary knowledge in the art within the technical idea of the present invention.
