Abstract

The present invention relates to a guard rail installed on the edge of a road to prevent overturning or leaving of a vehicle, and more particularly, to a shock absorbing guard rail that can effectively cushion a shock generated when a vehicle crashes.

Conventional guard rails use a guard rail consisting of a two-stage steel plate, and the impact rate of the impact energy is very low when the collision of the vehicle is delivered to the driver as the impact of the excessive impact energy generated in the crash as it is endangered life.

Therefore, the present invention is to secure the four-stage guard plate 11 and the buffer rod 15 and the buffer bolt 12 and the shock absorbing nut 16, the guard plate 11 is inserted into the concave-convex shape It is composed of the guard bolt 13, the hinge 19 and the support (10) when the impact on the one side of the guard plate 11 is configured to absorb the shock over four times occurs when the vehicle crashes It is possible to mitigate most of the shocks, and to protect valuable lives from crash accidents, and to make the width of the guard plate 11 wider than the standard type of the guard rail, minimizing the rollover or deviation of the vehicle in the event of a crash. This has the advantage.

Description

Shock-Resistant Guard Rails {A median strip of guid rail}

The present invention relates to a guard rail installed on the edge of the road to prevent overturning or departure of the vehicle, and particularly relates to a shock-reducing guard rail that can effectively cushion the impact generated when the vehicle crashes.

In general, guardrails are installed to minimize road departures that occur when driving on two or more lanes, such as highways, local roads, and car-only roads. The main purpose is to prevent and protect the driver's life.

Such guard rails are mainly made of steel plate guard rails and guard pipe type, guard cable, box type beams, etc. are used depending on the purpose. However, most of the guard rails are impacted by the guard plate 11 and the support 10 when the vehicle collides. The absorption rate of impact energy is very low, so the excessive impact energy generated in a collision is transmitted to the driver as it is, resulting in the endangerment of life.

The present invention was devised in view of the above problems, and an object thereof is to provide a shock-absorbing central separator that can absorb and cushion shock energy generated when a vehicle crashes in stages.

In order to achieve the above object, a feature of the present invention is that the folded metal guard plates 11, which are continuously bent and formed into an uneven shape, are installed in the road length direction, and the shock absorbing rod 15 is absorbed between the guard plates 11. Inserted into the upper and lower portions of the support (10) with the support (10) fitted behind the nut 16 and fixed to the bottom, the buffer bolt 12 and the nut (12a) and the fixing nut (20) fastened through them The hinge 19, which is fixed to the furnace post 10 and inserted into one of the centers of the guard plate 11, passes through them with the post 10 behind, and is fastened to the hinge bolt 18 and the nut 18a. The hinge plate 19 and the guard plate 11 are fastened and fixed by the guard bolt 13 through the holes penetrated by the long holes in the guard plate 11, and the guard plates 11 overlapping the left and right sides of the strut 10. By the shock-absorbing central separator, characterized in that the fastening to the guard bolt (13) through the hole through the long hole in the) It will be achieved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the guard plate 11 which is in direct contact with the vehicle has a metal plate that is continuously bent to form an uneven shape, and the guard plate 11 overlaps the longitudinal direction with the support post 10 behind. Is installed.

Behind the guard plate 11, the support 10 is fixed to the floor of the road at regular intervals, and the shock absorbing rod 15 is provided on one side between the support 10 and one side guard plate 11 to absorb the shock. In addition, the shock absorbing nut (16) is embedded in the shock absorbing rod (15) to effectively absorb the shock during shock, thereby inserting the shock absorbing bolt (12) through the hole penetrated through the guard plate (11) and the support (10). The fixing nut 20 and the nut 12a are fastened and fixed.

As shown in FIG. 4, the shock absorbing nut 16 contained in the shock absorbing rod 15 has a screw thread of the shock absorbing nut 16 fastened to the shock absorbing bolt 12 to be fixed. Shear stress is weak compared to the nut (12a) to absorb the shock while shearing first, and to increase and narrow the boiled width of the material and the thread of the shock absorbing nut 16, it is possible to adjust the shock absorption rate arbitrarily.

Behind the guard plate 11 is a support (10) is installed and fixed to the floor of the road and the support (10) connecting the support 10 and the guard plate 11 behind the support (10) and one side guard plate (11) It is inserted to one side and is fastened by the nut 18a by fastening the bolt bolt 18 through a hole penetrated by the hinge 19 and the support 10, and penetrated through the guard plate 11 and the hinge 19 The connection bolt 14 is fastened through the long hole to be fixed with the nut 14a.

At this time, the excessive force is generated in the hinge 19 and both wings of the hinge 19 are extended, so as to absorb the shock.

The guard plate 11 is fixed to the upper side of the support 10, the lower portion of the support 10 is buried in the bottom of the center line of the road is firmly fixed by the mortar and fixing reinforcement.

The guard plate 11 is bent in four stages to improve the bending stress and strength of the guard plate 11 and to widen the width of the guard plate 11 to minimize the departure or rollover of the vehicle during a collision.

The present invention made of the above-described configuration absorbs the first shock when the impact absorbing nut 16 breaks the initial shock when the vehicle collides with the one side guard plate 11, and the shock absorbing rod 15 is secondarily compressed. While absorbing, and absorbs the shock while the wings of the hinge 19 is spread three times, at this time guard plate 11 is spread between the first and third, depending on the bending stress and strength of the guard plate 11 Absorb the shock. Finally, the pillars fixed by the mortar and reinforcing bar can be absorbed and pushed back, so as to mitigate most of the impacts that occur during the crash, thus protecting valuable lives from crash accidents.

In addition, the projections of the both side guard plate 11 is formed of a concave-convex shape so that a high brightness reflector or a teleliner can be attached to enable direction indication or reflection, so that drivers can drive more safely.

The present invention as described above is the one side guard plate 11 formed in the concave-convex shape and the buffer rod 15 and the buffer bolt 12 and the shock absorbing nut 16 and the guard plate 11 inserted behind them It consists of a guard bolt (13) and a hinge (19) and the support (10) for fixing the shock absorber in four stages when the impact on one side of the guard plate (11) It is possible to mitigate most of the shocks generated during the crash, and to protect valuable lives from crash accidents, and to make the width of the guard plate 11 wider than the standard type of the guard rail, when the vehicle collides and rolls over. This has the advantage of minimizing accidents.
