Description

A guide rail of triple sheet of steel structure having a crash suction ability and method of guide rail with various absorption functions in a vehicle crash

The present invention relates to a guard rail of a triple iron plate structure having various absorption functions during a vehicle crash and a method of manufacturing the same. Particularly, when a vehicle collides with a guard rail, the guard rail absorbs a shock three times. It is easy to bend and in case of the second impact, the triple sheet plate absorbs the impact of the vehicle, thereby effectively protecting the vehicle collision and at the same time, the triple sheet plate part more firmly prevents the vehicle from falling off. The present invention relates to a guard rail of a triple iron plate structure having a function and a method of manufacturing the same.

In general, guardrails are installed on the side of a central divider or shoulder, such as a highway or national road, and these guardrails are installed at a certain interval so that a plurality of shores are buried in the ground, and then one side of the shores or By installing rails having bent buffer surfaces on both sides, it is possible to prevent the vehicle from escaping.

1 is a perspective view of a guard rail structure in which a guard rail is coupled to a support according to the related art, and FIG. 2 is a view illustrating cross-sectional shapes of guard rails coupled to the support shown in FIG. 1, respectively.

As shown in Figures 1 and 2, the guardrail structure is a guard rail 11 that absorbs the impact energy from the impacted vehicle, and the secondary absorbs the impact energy transmitted from the guard rail 11 and fixed to the ground It is composed of a support (10) and the fastening member 12 for fastening and fixing the guard rail 11 to the support (10). In the guardrail structure configured as described above, the guard rail 11 has various cross-sectional shapes to effectively absorb impact energy. Generally, the guardrail 11 used includes the W beam shown in FIG. 2A and the tree beam shown in FIG. 2B.

The W-beam is a cross-sectional width (W1) 350mm, corrugation width (C1) 50-75mm, plate thickness 3-5mm, mainly used in the guardrail structure installed in Korea. The tree beam is a cross-sectional shape having a cross section width (W2) of 460 mm, a corrugation width (C2) of 69 mm, and a sheet thickness of 3-5 mm.

In addition, the tri-beam is designed to cope with the height of a variety of vehicles from small cars to large cars, and recently used in the guardrail structure of the road like the W beam.

The guard rail 11 according to the related art, such as the W beam and the tree beam, absorbs the impact energy while deforming a rounded wave portion, and the coupling portion between the wave form and another wave form is fixed to the support 10 or another connecting member.

In the guard rail 11, the corrugated portion preferably has a performance of effectively absorbing impact energy while the shape thereof changes depending on the tension and rigidity of the guard rail 11 in the traveling direction of the colliding vehicle.

On the other hand, since the guardrail made of molded steel is highly rigid, improper cushioning (shock absorption) has occurred, resulting in more severe vehicle damage than the formed steel sheet. As a result, the shock is transmitted to the driver and the occupant as it is, causing serious injury. There was a problem.

In order to improve such a problem, the Republic of Korea Utility Model Publication No. 20-0295900 shown in Figure 3 is attached to the guard rail panel on one side of the pillar in the normal guard rail fastening with bolts and nuts A composite material consisting of a composite guardrail panel having a fluorescent layer formed on its surface, a hybrid strut divided into a composite shell and a core material, and a composite buffer member having a predetermined thickness mounted between the pillar and the composite guardrail panel. A guardrail is shown.

In the registration room as described above, the composite guardrail panel, hybrid strut, and the composite buffer member all have excellent effects in absorbing and mitigating impact. However, when the composite guardrail panel is damaged due to the impact of elastic deformation or more, There was a problem that could be a large accident falling into the cliff of the other lane, sidewalks, even under the bridge as well as cliffs.

In addition, the Republic of Korea Patent Registration No. 10-0478897 shown in Figure 4 is provided as a composite material as a whole and at least one steel wire, aramid bar, high tensile bar, etc. in the longitudinal direction of the buried installation of the composite material primarily impact This suggests that the guardrail can be alleviated and the inner wire inside the composite member prevents the secondary from overriding the guardrail. The production of the guardrail becomes very difficult because the wire must be mounted inside the guardrail. There was this.

An object of the present invention has been researched and developed in order to solve the above-mentioned conventional problems, to provide a guard rail to alleviate the collision of the vehicle over three times, and at the same time the third iron plate is firmly prevented from leaving the vehicle The rail is composed of a primary protective panel consisting of a single steel plate, a secondary protective panel consisting of a triple iron plate, and a tertiary protective panel consisting of a protruding rectangular panel, wherein the single layered steel sheet and the triple iron plate are made of one iron plate. The object of the present invention is to provide a guard rail that can be bent to be manufactured to absorb shocks three times and increase convenience of manufacturing.

As a means for achieving the above object,

The present invention is a primary defense panel formed of two or more triangular, trapezoidal or semicircular form; It is installed in the middle of the primary defense panel, respectively formed on both sides and connected integrally with the primary defense panel, and the secondary defense panel consisting of triple iron plate of obtuse angle shape with a slanted shape and a vertical plane around the bending point. and; A third defense panel installed at a center point of the second defense panel in a triangular, square, trapezoidal or semicircular form and absorbing a third impact; Fixing means installed through the triple iron plate of the secondary defense panel to fix the triple iron plate; It characterized in that it comprises a guard rail coupling means for connecting the triple iron plate and the support rod to the guard rail is coupled to the support rod.

Components of the guardrail 100 of the present invention includes a primary defense panel 10 formed of two or more triangular, trapezoidal, or semicircular shapes;

A secondary defense panel 20 formed on both sides of the primary defense panel and being integrally connected to the primary defense panel and integrally connected to the primary defense panel, the second defense panel being made of a triple iron plate obliquely shaped and having a bent shape around a bending point;

A third defense panel 30 installed at a center point of the second defense panel in a triangular, square, trapezoidal, or semicircular shape and absorbing a third impact;

A triple iron plate fixing means 120 installed while penetrating the triple iron plate of the secondary defense panel to fix the triple iron plate;

It comprises a guard rail coupling means 110 for connecting the triple iron plate and the support rod to the guard rail is coupled to the support rod.

Two or more primary defense panels 10 are installed around the support rods, and preferably two or three are configured in the form of triangles. In the drawing, the first defense panel is formed in the form of a general mountain and is composed of two mountains in total. However, three or more mountains can be installed as necessary, as well as a trapezoidal shape or a semicircular shape in which both sides are inclined and the center is straight. It can be configured as.

The primary defense panel 10 may minimize the impact applied to the vehicle while preventing the vehicle from progressing while the vehicle is primarily folded when the vehicle collides with the guide rail. If the vehicle is small and the speed is low, the vehicle is stopped while the primary defense panel is bent when the vehicle collides. At this time, the primary defense panel 10 is easily bent to minimize the impact on the vehicle. As a result, the impact on the occupant of the vehicle can be minimized.

The secondary defense panel 20 is installed at the intermediate point of the primary defense panel, when the first defense panel 10 is composed of two mountains, the secondary defense panel is installed at one point, and three When the mountain constitutes the primary defense panel 10, the secondary defense panel is installed at two points. If the primary defense panel 10 is composed of four mountains, the secondary defense panel is installed at three points. Therefore, it can be seen that the secondary defense panel 20 is installed by one less than the number of mountains of the primary defense panel.

The secondary defense panel 20 is made of a triple iron plate, is integrally connected to the primary defense panel 10, is installed on the edge of the primary defense panel.

At this time, the secondary defense panel 20 is installed on both sides of the primary defense panel, respectively, in the form of a needle-shaped around the bending point to install a vertical surface inclined so that the obtuse angle as a whole.

Since the secondary defense panel 20 is composed of a triple iron plate, it serves to block the flow of the vehicle more strongly when the vehicle proceeds continuously in a state in which the primary defense panel 10 is bent.

In particular, since the secondary defense panel 20 is composed of triple, it is possible to block the flow of the vehicle with three times or more strength compared to the primary defense panel 10, and thus a medium or large vehicle or a small and speed The fast vehicle bends the first defense panel 10 and proceeds again to bend the second defense panel. At this time, since the second defense panel 20 is composed of triple iron plates, the vehicle is strongly prevented from flowing. You can do it.

In addition, by using a bolt and nut as a means for fixing the triple iron plate every fixed point, thereby fundamentally preventing the configuration of the triple iron plate.

If the fixing means for fixing the triple iron plate is not added, the triple structure may be dismantled in a collision, which makes it difficult to stop the strong collision. Therefore, in the present invention, a fixing means for fixing the triple iron plate is added to prevent the triple structure from being dismantled.

The third defense panel 30 is installed in a triangular, square, trapezoidal or semi-circular form at the center point of the secondary defense panel to absorb the vehicle shock in the third.

In the present invention, a rectangular protrusion is proposed as a preferred form, and when the vehicle proceeds while completely bending the secondary defense panel, the third defense panel finally blocks the flow of the vehicle and distributes the impact caused by the collision of the vehicle. Allow the rail to absorb shocks smoothly.

That is, when all of the secondary defense panel 20 is bent, the third defense panel is finally in contact with the vehicle. At this time, since the third defense panel 30 is protruded, it is bent while colliding with the vehicle at the last. The vehicle absorbs the shock, thereby reducing the impact on the vehicle occupant as well as reducing the impact on the outside of the vehicle by absorbing the impact of the tertiary defense panel 30.

As a result, the present invention absorbs the impact caused by the first vehicle collision through the primary defense panel 10, and when the vehicle breaks through the primary defense panel 10, through the secondary defense panel 20 made of triple iron plates. Absorbing the impact caused by the collision of the vehicle strongly prevents the progress of the vehicle, and after the vehicle rushes in a state in which the secondary defense panel 20 is fully bent, the third defense panel 30 that finally formed a protrusion is the vehicle By absorbing the shock of the vehicle to absorb the shock of the vehicle three times, so that the shock to the outside of the vehicle can be absorbed as much as possible, and the impact inside the vehicle can be minimized to protect the driver.

The guardrail coupling means 110 is to connect the support rod to the secondary defense panel 20 made of a triple iron plate so that the guard rail 100 is coupled to the support rod 200, of the secondary defense panel 20 Since the two points are joined to the support rods, a stronger bond is maintained, allowing the guardrail to be securely fixed to the support rods.

The manufacturing method of the guardrail shock absorption panel of this invention is as follows.

First, prepare a rectangular panel.

Thereafter, the center point is formed into a protruding rectangular panel, and triple iron plates are formed on both sides of the protruding rectangular panel.

Thereafter, both sides of the triple iron plate are bent at an obtuse angle, so that one layer of iron plate continuously constitutes two acids.

Thereafter, the triple iron plate is fixed with the triple iron plate fixing means 120, and when the manufacture of the panel is completed, the support rod 200 is contacted and then fixed from the triple iron plate portion to the support rod by the guard rail coupling means 110. .
