Shock-absorbing protective structure for roads {PROTECTION STRUCTURE OF SHOCK-ABSORBING FOR ROAD}

The present invention relates to a shock absorbing protective structure for a road, and more particularly, to a shock absorbing protective structure for a road, the parts are simplified to improve the absorbing power to the impact generated during a vehicle crash.

Generally, on the road, the vehicle may leave the road due to a driving error or an unexpected obstacle while driving. In such a case, it is necessary to minimize the injuries of the occupants and the damage of the vehicle and to return the vehicle to the normal traveling direction while preventing the vehicle from escaping from the set road.

In this way, safety facilities such as barriers, guards, and guard rails are installed on the road to prevent the vehicle from crossing the center line of the road or passing through the edge of the road. For example, in the related art, an elastic rotary shock alleviator is disclosed and is in progress.

The conventional technology prevents the vehicle from leaving the road while the elastic rotating roller rotates about the rotation support shaft when the vehicle collides with the elastic rotating roller, and the elastic rotating roller itself also absorbs the impact of the vehicle.

However, in the prior art as described above, the elastic rotary roller is placed in close contact with the ground on the road, so that the elastic rotary roller is hardly rotated by friction with the ground depending on the colliding angle. There is a problem that is broken itself.

And, in the prior art, the elastic rotary roller is to be relatively rotated with the rotary support shaft, there is a problem that the elastic rotary roller is easily damaged by friction between the elastic rotary roller and the rotary support shaft. In particular, the elastic rotating roller is preferably made of a material that is easy to elastically deform, but it is disadvantageous to use a material that is easily elastically deformed in order to prevent damage due to relative friction between the elastic rotating roller and the support shaft. There is also.

When the third support reinforcement unit is installed on a plurality of struts spaced apart from each other, when the third support reinforcement unit installed in one support and the other support adjacent to it is repeatedly unit-arranged from the support posts, the insertion hole of one side of the third support reinforcement is The right side facing the gap between the front and rear joining plates formed on the left side or the right side of the third supporting force reinforcing body so that the formed right side and the right side where the insertion hole of the other third supporting force reinforcing body is closely overlapped with each other, or The shock absorbing protective structure for a road, characterized in that it is formed to have a larger gap than the gap between the front and rear coupling plate of the left portion. delete The method of claim 1,
The coupling between the upper side of the upper safety rail and the upper side of the revolving roller corresponding to the struts while being coupled to each other and coupled to the struts adjacent to the struts, respectively, coupled to one side of each side of the struts The second connecting piece is connected at each end of the piece and the coupling piece and symmetrically extended to each other in a predetermined inclination and the other end of the second connecting piece is curved to each other to form a third curved portion of the other side formed with a second fastening hole in the center A fourth supporting force reinforcing body having an integral structure is further included, wherein a third curved portion adjacent to each of the fourth supporting force reinforcing bodies respectively disposed symmetrically between the support and the support is interviewed to fasten the fastening means to the second fastening hole. Shock absorbing protective structure for the road, characterized in that the fixing. The method of claim 1,
It is disposed on the upper side of the upper safety rail and the upper portion of the elastic rotating roller and the upper side of the lower safety rail and the upper portion of the elastic rotating roller, respectively, to surround the outer circumferential surface of the support so as to connect and couple between the support and the neighboring support. Both ends of the first binding portion having a shape corresponding to the outer circumferential surface of the support and the first binding portion extend forward and backward symmetry of a predetermined inclination and are connected to the first reinforcing portion and the first reinforcing portion which are connected to each other by being overlapped with each other. A second binding having a shape corresponding to an outer circumferential surface of the support such that the second reinforcement and the second reinforcement extending in a forward and backward symmetry of a predetermined slope are connected to each other to be interviewed with the other surface of the support adjacent to the support; Shock absorbing protective structure for a road, characterized in that further comprising a fifth supporting force reinforcing body composed of a portion. The method of claim 1,
The lower safety rails coupled to the lower both sides of the support are not directly coupled to each other, and the front lower safety rails and the rear lower safety rails respectively coupled to the lower both sides of the support are coupled back and forth symmetrically with each other. And a second buffer space therein so as to have a structure that is integrally coupled with each other, the one end is interviewed on the shore, and the other end is joined to the rear side of the lower safety rail. Shock absorbing protective structure for the road, characterized in that the buffer reinforcement further comprises.
