Description

Guard Rail Structure

The present invention relates to a guardrail structure, and more particularly, to a guardrail structure that can be installed between the upper rail and the lower rail to prevent the upper guard rail and the lower guard rail from spreading up and down in a vehicle crash.

In general, the guardrail structure is installed along the center line of the road, that is, along the yellow solid line that defines the driving width of the road. It prevents large-scale collisions in advance or is installed on the edge of roads or bridges to prevent departure of driving vehicles.

Typically, the guardrail structure includes a plurality of struts vertically installed at regular intervals along a center or side of the road, and a W-shaped bumpy guardrail horizontally connecting the struts.

The guardrail structure installed at the center of the road is paired side by side in a state where the guard rails are spaced apart at regular intervals on both sides of the support part, and the guard rail structure installed at the side of the road is installed only on one side of the support part. There are many.

In addition, the guard rail of the guardrail structure is installed at a predetermined distance apart from each of the upper and lower portions of the support so as to protect all the vehicles from a low passenger car to a high vehicle.

However, in the conventional guard rail structure, when the vehicle collides between the support part and the support part, since the guard rail is coupled to the support part, the upper guard rail and the lower guard rail open to the upper side and the lower side, Often times the function did not work properly. In particular, since the guardrail structure on the roadside is composed of only one layer of the guardrail on the strut, when the vehicle collides with the guardrail structure on the roadside, the upper guardrail and the lower guardrail are opened. In particular, the lower guard rail is likely to lead to a large accident because the wheel portion of the vehicle acts as a foothold that can ride off.

The present invention has been made to solve the above problems, an object of the present invention to securely hold between the upper guard rail and the lower guard rail so that the upper guard rail and the lower guard rail does not open during a vehicle crash. The present invention provides a guardrail structure that can be effectively deformed and improves the vehicle protection function by increasing the cushioning performance.

The present invention for achieving the above object, and a plurality of struts vertically installed on the road at regular intervals; An upper guard rail and a lower guard rail which are horizontally connected between the support parts and installed side by side at a predetermined distance apart from each other in the vertical direction; A reinforcement bracket having an upper end fixedly coupled to the upper guard rail, and a lower end fixedly coupled to the lower guard rail, and a buffer part protruding integrally from the upper guard rail and the lower guard rail in the middle part is protruded integrally. Provided is a guardrail structure comprising a.

According to the present invention, since the upper guard rail and the lower guard rail are fixed by the reinforcing bracket, the phenomenon of the upper guard rail and the lower guard rail spreading up and down when the vehicle collides with the upper guard rail and the lower guard rail between the support parts is suppressed. At the same time, the cushioning portion of the reinforcing bracket is crushed to absorb the shock, thereby further improving the cushioning effect and the vehicle protection function.

Hereinafter, exemplary embodiments of the guardrail structure according to the present invention will be described in detail with reference to the accompanying drawings.

First, Figures 1 to 4 show the guardrail structure according to the first embodiment of the present invention, the guardrail structure of the present invention is a plurality of struts 10 are installed vertically at regular intervals on the road and the support The upper guard rail 21 and the lower guard rail 22 which are horizontally connected between the main parts 10 and installed side by side at a predetermined distance apart from each other in the vertical direction to the support part 10, and between the support parts 10. It is disposed in the upper and lower end portion comprises a reinforcing bracket 30 is fixed to the upper guard rail 21 and the lower guard rail 22, respectively.

The support 10 is made of a circular or polygonal beam (beam), is fixed at regular intervals along the center line or road side of the road.

The upper guard rail 21 and the lower guard rail 22 are fixed to the support part 10 by fastening means such as bolts 11. The upper guard rail 21 and the lower guard rail 22 have a shape similar to the known guard rails, in which the upper guard rail 21 and the lower guard rail 22 are approximately 'W' shaped. It consists of a curved elongated metal plate.

The reinforcing bracket 30 has a rectangular plate shape in which both sides are bent at right angles, and fastening holes 33 having long holes are formed at upper and lower ends, respectively. Therefore, the upper and lower ends of the reinforcing bracket 30 are firmly fixed to the upper guard rail 21 and the lower guard rail 22 by fastening the fastening means such as the bolt 35 through the fastening holes 33. . In this way, the reinforcing bracket 30 is connected to the upper guard rail 21 and the lower guard rail 22 integrally to act to reinforce the strength of the portion between the relatively weak holding portions 10.

The reinforcing bracket 30 is integrally formed in the middle portion of the buffer unit 31 protruding into the space between the upper guard rail 21 and the lower guard rail 22 integrally. The buffer part 31 may be made by pressing the reinforcement bracket 30. The buffer part 31 protrudes through the space between the upper guard rail 21 and the lower guard rail 22 so that the shock absorbing part 31 comes into direct contact with the vehicle when the vehicle collides with the guard rail structure. . As such, the shock absorbing portion 31 acts as a shock absorber while causing the deformation to collapse during a vehicle crash.

In this embodiment, the shock absorbing portion 31 has a rectangular parallelepiped shape, and each of the upper and lower surfaces has a structure in which the opening portion 32 communicates inward and outward. As such, when the open part 32 is formed in the shock absorbing part 31, the shock absorbing part 31 may be smoothly crushed while the vehicle collides to absorb the shock.

Of course, in this embodiment the opening 32 is formed at the top and bottom of the buffer 31, but as shown in Figs. 5 and 6 the opening 32 is provided on both sides of the buffer 31 It may be formed.

In addition, in the above-described embodiments, the buffer part 31 may have a rectangular parallelepiped shape, but may be formed in various forms. For example, as illustrated in FIGS. 7 and 8, the buffer part 31 of the reinforcing bracket 30 may have a triangular prism shape in which one surface is inclined and an opening part 32 is formed on the upper and lower surfaces thereof. . Here, the inclined surface of the shock absorbing portion 31 is preferably inclined in a direction facing the traveling direction of the vehicle, which is to protect the vehicle by hitting the inclined surface of the shock absorbing portion 31 as much as possible It is intended to be crushed.

In addition, as shown in FIGS. 9 and 10, one surface may be formed to be inclined and may have a triangular prism form in which opening portions 32 are formed at both sides. In addition, any variety of shapes, such as cylindrical form, will be possible.

In addition, although the buffer portions 31 of the reinforcing bracket 30 according to the above-described embodiment are formed in a single shape, as shown in FIGS. 11 and 12, an open portion 32 is formed on the upper and lower surfaces thereof. A plurality of shock absorbing portions 31 may be formed (two in this embodiment).

In addition, as shown in FIGS. 13 and 14, a plurality of buffer portions 31 (two in this embodiment) may be formed in the form of a rectangular parallelepiped in which opening portions 32 are formed on both sides.

Although the above-described buffer part 31 of the reinforcing bracket 30 has a structure in which the opening part 32 is formed at the upper side, the lower side, or the side surface, the shock absorbing part as shown in another embodiment in FIGS. 15 to 21. An open portion may not be formed at 31 and may have a completely closed form. 15 and 16 show that the shock absorbing portion 31 of the reinforcing bracket 30 has a rectangular parallelepiped shape, and FIGS. 17 and 18 show that the shock absorbing portion 31 has a dome shape. 19 to 21 show a structure in which the buffer part 31 is divided into a plurality.

In addition, in the above-described embodiment, only one reinforcing bracket 30 is configured between the holding portions 10 (see FIG. 1), but alternatively, a plurality of reinforcing brackets 30 may be installed at predetermined intervals.

As described above, in the guard rail structure of the present invention, since the reinforcing bracket 30 is fixedly coupled to the upper guard rail 21 and the lower guard rail 22 between the support parts 10, the vehicle is connected between the support parts 10. When the upper guard rail 21 and the lower guard rail 22 collide with each other, the phenomenon in which the upper guard rail 21 and the lower guard rail 22 spread upward and downward is suppressed. Therefore, the vehicle is prevented from being separated from the guardrail structure to cause a large accident. In addition, when the vehicle collides with the guardrail structure, the vehicle collides with the shock absorbing portion 31 of the reinforcing bracket 30 to absorb the shock while the shock absorbing portion 31 is distorted, thereby obtaining a further improved shock absorbing effect.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. In addition, it is apparent that any person having ordinary knowledge in the technical field to which the present invention belongs may make various modifications and imitations without departing from the scope of the technical idea of the present invention.
