Description

GUARD RAIL FOR A ROAD}

The present invention relates to a structure in which the central separator of various roads is installed to have a predetermined shock-absorbing buffer structure, in particular, which is installed on both left and right sides with a main pillar installed at a constant interval and the main pillar interposed therebetween. In the guard rail, by fixing the shock absorbing bracket of the shape bent in a simple structure on the left and right outer peripheral surface of the main pillar, there is a convenience and economical usefulness according to the installation work and the manufacture of the bracket by installing the guard rail on the bracket, If the vehicle collides with the guard rail in both the left and right directions, the bent shock absorbing bracket expands and absorbs the shock efficiently (i.e. the same as the operation of the leaf spring). Improved function of the cushioned road median for the optional replacement of guard rails Relate to.

In general, fatal accidents can be caused by small carelessness on roads that are rapidly bent or roads that run at high speeds, and when the vehicle is driven in bad weather conditions, the central line may be accompanied by poor visibility and slipping. As the incident occurred, there were many casualties and economic losses due to collision with the oncoming vehicle.

Therefore, the central divider is installed on various roads to promote the safe operation of the vehicle, mainly by selecting the highway or the central line portion of the road in the general national road to install the divider to the concrete structure or one of the two sides of the main pillar of the general guardrail The clamp is connected to both sides of the end of the fixed support member by fastening the guard rail to the pillar using a bolt or by using a bolt on a side or both sides of the pillar. It is practical to attach and use, but in Korea, the median divider on the road is almost never installed, and the steel divider is installed to effectively protect and prevent occupant safety and vehicle destruction in the event of a vehicle crash. It has a very incomplete structure.

That is, the center separator provided with steel is provided to prevent the invasion of the center line of the vehicle, the conventional existing steel center separator can be fixed to the ground and a pair of side-by-side guardrail toward the inside of the driving lane can be installed. After securing a separate support member so that the gap width of each guard rail can be kept constant, a pair of guard rails are positioned at regular intervals, and then the guard rail support members are screwed into the bowl using a clamp. It was.

Since the steel separator is formed with a length of 50cm and 80cm, the width of the road is very narrow in highways and national roads, especially in local roads. Except for wide roads, it is practically very difficult and the speed of the vehicle can be limited by narrowing the width of the left and right roads according to the installation of the central separator.In bad weather, the central separator installed for road safety is rather in contact. It caused the accident.

In addition, the steel central separator using the supporting member and the clamp was very large in the rigidity of the central separator, and it was insufficient to effectively protect the safety of the vehicle occupant and the vehicle destruction by the fixed rigidity of the supporting member. In addition to the excessive use of steel materials, the inconvenience of having to manufacture a support member separately caused an increase in cost and the hassle of manufacturing, and accompanied an excessive demand for construction time.

In addition, the steel central separator is a rigid support member installed on both sides of the main column when the vehicle crashed very strong, so that when the vehicle collides with the central separator, the impact is doubled without absorbing the impact. They were so strong that they often bounced over and overturned, resulting in increased vehicle destruction.

Accordingly, an object of the present invention is to provide a bent bracket having a cushioning function, such as a leaf spring, in place of a support member disposed between the main pillar and the guard rail and installed for maintaining and supporting the gap between the guard rails. The installation has the purpose of making the safety of the occupants and the vehicle as well as the convenience of manufacture and the usefulness of the installation as well as being given sufficient absorbency according to the collision with the vehicle after installation.

In order to achieve the above object, the present invention is to bend the metal plate on the plate maintaining the same height and width as the guard rail in the c-shape, and the end of both side plates to be in close contact with the guardrail at a right angle to the curved cross-sectional structure After forming the inclined groove portion is formed in a shape, the center portion is cut horizontally to both sides for the formation of the groove portion to provide a shock absorbing bracket including a wing formed with a fastening hole, and the bracket Fasten and fasten the bolts so that the back of the plate is in close contact with both sides of the left and right, and then the guard rail is fastened to the front left and right brackets.
