Description

Median strip of highway}

The present invention relates to a road central separator installed in the center of the road to prevent a large traffic accident due to the center line of the vehicle, the upper plate inserted through the support rod is fixed to the upper portion of the lower plate, between the support rod and the lower plate Elastic means for providing an elastic force is provided, when there is an external impact due to a collision by the vehicle, the upper plate flows to the left and right to be able to be restored to the original by the elastic restoring force, it is easily broken even by a vehicle collision The present invention relates to a road divider capable of minimizing impact on a vehicle without being dislodged.

In recent years, traffic has surged due to the rapidly increasing vehicles, and traffic accidents that have killed lives due to contact between the vehicles and the invasion of the central line have soared.

In order to reduce such traffic accidents, various safety traffic facilities are drafted and used.

The central divider of the safety traffic facilities is installed along the center of the road to prevent the vehicle from crossing the other side of the road to prevent large accidents caused by the invasion of the center line, and the driver to recognize the linearity of the road at night It is used as a means to promote safe driving.

1 is a perspective view of a conventional general separator.

As shown in the figure, the conventional common separator is a security barrier (1) that is continuously installed along the center of the road, and a plurality of fixing rods (8) arranged at equal intervals along the top surface (5) of the security barrier (1) ) And a plurality of light shielding plates 9 attached between the fixing rods 8.

The barrier wall 1 is formed of a heavy chain concrete to prevent the vehicle from crossing over to the opposite side of the road, and the lower end portion 2 of the lower side is higher than the height of the tire so that when the vehicle collides, the tire first comes into contact with the vehicle. It is formed to be lower, and to form an inclined portion (3) that is narrowed inward to prevent damage to the vehicle body in the event of a collision of the vehicle leading to the upper side of the lower portion (2), while leading to the upper side of the inclined portion (3) It has a shape having a vertical portion 4 to maintain the height while forming a gentle inclination angle to the top.

In addition, fixing rods 8 are disposed by screwing at equal intervals along the upper end surface 5 of the barrier wall 1, and between the fixing rods 8, light emitted from a vehicle in a relative lane is provided. A light shielding plate 9 made of plastic or steel is installed to prevent the driver's visual disturbance.

In addition, in some cases, fluorescent paints for inducing gaze may be painted on the vertical portion 4 of the barrier wall 1 for safety operation.

However, as described above, the conventional general separator is made of cement, plastic, and the like, and when the vehicle accidentally collides with the separator, it cannot endure the impact and its original shape is destroyed or greatly damaged, and the impact on the vehicle is large. There was a problem that the vehicle body is badly damaged.

In addition, when the conventional center separator is to be installed on the road, it requires a wide space of 1 m or more, so in the case of a narrow road, there is a problem that its installation is not easy.

The present invention is devised to solve the above problems, the object of the present invention is the upper plate is inserted into the support rod is fixed to the upper portion of the lower plate, the elastic means for providing an elastic force between the support rod and the lower plate is provided To prevent the vehicle from crossing over to the other side of the road, and when there is an external impact due to a collision by the vehicle, the upper plate flows to the left and right to be restored to its original state by the elastic restoring force, and the upper plate and the lower plate. This elastic material is made of elastic material such as rubber, urethane, synthetic resin, etc., which prevents damage caused by collision of the vehicle, has excellent resilience, minimizes the impact on the vehicle, and can be installed in a narrow space of the existing road. To provide a median separator.

In addition, the upper plate 50 coupled to the upper portion of the lower plate 20 is formed with a vent hole 90 penetrating through the left and right side to reduce the resistance of the wind blowing from the left and right sides.

Hereinafter, the operation and effects of the present invention will be described in detail.

11 is an operating state diagram showing an operating state of the central separator according to the present invention.

As described above, the central separator for the road according to the present invention includes a plurality of support rods 42 penetrating and inserted into the upper plate 50 between the supports 30 at an upper portion of the lower plate 20 formed of a hollow body. It is fitted into the recess 34 formed in the fixed portion, and the elastic means for providing an elastic force between the support member 26 and the lower end of the support bar 42 in the lower plate 20 is connected.

The central separator configured as described above is installed along the center line of the road, thereby preventing the vehicle from crossing over to the opposite roadway, thereby preventing a large accident due to the center line invasion.

At this time, the center separator is to completely block the center line, thereby fundamentally suppress the driver's lane invasion desire to double the effect.

However, when the central separator is impacted by the vehicle due to the driver's carelessness or the like, as shown in FIG. 11, the upper plate 50 fixed by the support 30 is bent to the left and right. In the lower plate 20, the supporting rod 42 is elastically restored between the support member 26 and the lower end of the supporting rod 42 to be restored to its original position.

That is, as the upper plate 50 is bent, the lower end of the support bar 42 is also bent in one direction, and the support bar 42 is returned to its original position by the elastic restoring force of the elastic body 60 connected to the lower end of the support bar 42. The upper plate 50 is also restored to its original position while being restored to.

At this time, the upper plate 50 and the lower plate 20 and the support 30 is made of an elastic material such as rubber, urethane, synthetic resin with a strong elastic force is prevented from being easily damaged by the collision of the vehicle, to increase the resilience do.

Then, through the drain portion 87 formed in the lower plate 20, as in the third embodiment, rainwater and the like flow smoothly across the center separator, and water is prevented from accumulating on the road, and vent holes 90 are provided on the upper surface. ) Is formed to lower the resistance to wind blowing from the side.

In addition, when fixing the central separator to the road surface through the assembling hole 82 formed in the upper surface of the lower plate 20 can be assembled to the nut 19 inside the lower plate 20 to increase the efficiency of the work, assembly Afterwards, the assembly hole 82 can be simply closed by the hole stopper 84.

And, if you want to install a central separator made of concrete on the road requires a wide space of 1m or more, while the central separator according to the present invention can be manufactured in a small size requires a space of about 30 ~ 40㎝ Since it is possible to install even in the narrow space of the existing road.

As described above, according to the road center separator according to the present invention, the upper plate through which the supporting rod is inserted is fixed to the upper portion of the lower plate, and elastic means for providing an elastic force between the supporting rod and the lower plate is provided, so that the vehicle is on the opposite roadway. To prevent the fall, when the external impact due to the impact of the vehicle, the upper plate flows to the left and right to allow the original recovery by the elastic restoring force, the upper plate and the lower plate is a resilient elastic material Consists of preventing damage caused by a collision, excellent resilience, can minimize the impact on the vehicle, there is an effect that can be installed in a narrow space of the existing road.
