Description

Guard rail having a reinforcing agent

The present invention relates to a guard rail having a reinforcement, and more particularly, in the attachment of the guard rail installed at the edge of the road to the support, the vehicle collides with the guard rail by installing a separate reinforcement between the support and the guard rail. When the exposed part of the guardrail support installed buried in the ground due to the impact is bent to the outside, the guardrail plate attached to the upper part of the support is pushed together, and the trajectory of the circle drawn is increased so that the crashed vehicle crosses the guardrail. By preventing them from going, it is possible to prevent them from leading to major accidents.

In general, at the edges of highways and national roads, as well as downtown main roads, vehicles that misalign their driving directions due to inexperienced driving or other reasons are prevented from falling off the road and falling down. Alternatively, guard rails are installed repeatedly to protect the main facilities along the road, and most of these guard rails are partially buried at the base of the ground to the outside of curbs installed for drainage purposes at the edge of the road. A guard rail plate having a corrugated side cross section was bolted directly to the upper part of the post which was installed in a state so that the guard rail plate prevented the vehicle from passing outside the road in the event of an impact of a vehicle trying to leave the road.

However, the conventional guard rail having the structure as described above simply bolts the guard rail plate using a narrow hinge on one side of the upper end of the support, so the position of the guard rail plate is more outward than the road adjacent surface of the curb. When the vehicle is driven away from the normal road driving category, the vehicle is in contact with the curb first, and the other side of the impact part of the vehicle is lifted by the impact. After the collision, the guardrail to which the guardrail is attached is bent to the outside of the road by using the buried part as a point of the vehicle. In this process, the vehicle that impacts the guardrail As you go down the road to the outside of the road was a problem that leads to a large accident.

In the collision of the vehicle against the series of guardrails, the guardrail struts that are shocked due to the installation structure of the conventional guardrails are bent to the buried part, and the trajectory of the circle drawn while the props are bent (rotated) is Since the distance from the ground (road surface) to the top of the guardrail plate was shortened, the vehicle that impacted the guardrail had to easily go outside the road on the guardrail, leading to a large accident.

Therefore, the object of the present invention is to solve the problems of the conventional guard rail by simply assembling a narrow hinge between the guard rail plate on one side of the upper end as described above, the guard rail plate installed on the support After connecting the reinforcement having a certain size (width) to the strut without direct bolt assembly, the guardrail plate is installed on the front side of the connected reinforcement, so that the road facing surface of curbstone installed at the front of the guardrail plate and the road edge is about the same. It is located on the vertical line so that when the vehicle is impacted on the guard rail, the wheels contact the curb surface, and the vehicle body also contacts the guard rail at the same time, thereby preventing the primary lifting phenomenon of the vehicle impacting the curb and the guard rail. Rather, the vehicle is bent out of the road due to the impact of the vehicle, and the trajectory of the circle drawn by the guardrail plate of the prop is enlarged to It is to provide a guardrail having a reinforcement which can effectively prevent the occurrence of a large accident due to the vehicle crash by preventing the vehicle from easily crossing the guardrail by increasing the distance from the top of the guardrail plate.

DESCRIPTION OF SYMBOLS 1 Shore 2 Guardrail plate 3 Reinforcement

In order to achieve the above object, the guard rail having the reinforcing material of the present invention is installed at the edge of the road, the guard rail (A) for preventing the departure of the running vehicle, so that the lower portion is embedded at the edge of the road A separate reinforcement 3 is installed on one side of the upper end of the support 1 to be installed, and a normal guard rail plate 2 is attached to the front side of the reinforcement 3.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

Figure 1 is a partially enlarged side view showing the configuration of the guardrail according to the present invention, Figure 2 is a partially enlarged plan view showing the configuration of the guardrail according to the present invention, Figure 3 is an installation and use state of the guardrail according to the present invention As a side view which shows, the structure consists of a structure which installs the reinforcing material 3 between the support | pillar 1 and the guardrail board 2. As shown in FIG.

The pillar (1) is made of H beam, etc. for the firm installation of the guardrail plate, and the lower part is buried in the ground partly and the upper part is exposed to the outside of a certain length with a certain interval at the edge of the road (4). A number of are installed. At this time, the support (1), the road (4) is installed on the edge of the road (4) selectively curb (5) for preventing the primary departure of the vehicle, or both the road (4) is not installed curb 5 Applicable to, it can be installed at the edge of the road (4) regardless of whether the curb (5) is installed.

The guardrail plate 2 is also a known metal guardrail plate 2 having a substantially corrugated side cross section, and is attached to the support 1 via a reinforcing material 3.

The reinforcement 3 is composed of the same H beam as the support 1, and is attached to one side of the upper end of the support 1 by fixing means 6 such as bolts and nuts, respectively, and at the same time as the front face (road-directed surface). Also, the guard rail plate 2 is attached to and installed by fixing means 6 such as bolts and nuts.

At this time, the material of the reinforcing material (3) is not limited to the H beam of the above-described steel, and can be applied to the reinforcing material (3) made of a synthetic resin material of the same size wood or plastic having a certain strength. It is not specific.

Thus, the guard rail plate (2) is not directly attached to the upper end of the support (1), but the guard rail plate (2) is attached to the upper end of the support (1) via a separate reinforcement (3). 2) The front and the curb faces of the curb (5) are located almost in the same vertical line, so that the wheel part and the body part of the vehicle to the curb plate (2) of the curb (5) and the guard rail (A) during the impact By contacting and impacting at the same time, it is possible to prevent the fall of the vehicle or the vehicle to fall off the road.

In addition, the guard rail plate (2) is attached and installed at a certain distance from the one side of the top of the support (1), so that the upper end of the support (1) when the vehicle impacts bent outwards to the buried part ( As the trajectory of the drawing circle becomes much larger than the conventional guard rail, the height of the guard rail plate 2 can be kept high during the initial post bending step during vehicle impact, thereby impacting the guard rail A. The probability of the vehicle falling over the guardrail A to fall off the road becomes lower that much, so even if an accident that causes the vehicle to impact the guard rail A occurs, the vehicle falls to the outside of the road. It can be prevented in advance.

As described above, although the present invention has been described with reference to the above embodiments, it is not necessarily limited thereto, and various modifications may be made without departing from the scope and spirit of the present invention.

As can be clearly seen from the above description, according to the guardrail having the reinforcement of the present invention, the guardrail plate closer to the road side is provided by attaching and installing the guardrail plate forming the guardrail on the upper end side of the strut with a certain size of reinforcement in between. When the vehicle is impacted by the guardrail, the wheel is contacted with the curb at the edge of the road and the vehicle body is directly impacted by the guardrail plate to prevent the vehicle from falling or overturning. Not only can it be prevented, but the impacted prop has a larger trajectory of the circle that is drawn during the initial bending motion, and the guardrail plate position is kept higher from the road surface. It provides useful effects such as preventing the occurrence of outgoing large accidents in advance.
