Description

A Guard Rail using fense with U section formation for vehicle}

The present invention relates to a vehicle protection fence using a cross beam having a "U" cross-sectional structure, and more specifically, to a closed end of a "U" cylindrical structure rather than a twin structure manufactured by bending or forming a cross beam of a vehicle protection fence. It is composed of a surface to maximize the strength, and a shock absorbing effect in the case of external impact by the vehicle, and a high impact strength vehicle protection fence.

In general, protection fences are facilities installed on bridges or roadsides or in the centers to prevent vehicle misaligned in the direction of driving during departure, and to protect the occupants and vehicles safely. It is used to restore the driver's eyes to normal driving direction and to induce the driver's gaze and to suppress the pedestrian crossing.

The conventional protective fence is attached to the strut separately, so that only the attachment part acts as a buffer, and the cross beam is used to open the round pipe or the sheet bending, so it is not a closed section when impacted by an external vehicle. This has the disadvantage of returning to its original state.

The present invention has been devised to solve the above drawbacks, and by maximizing strength by constructing the closed section of the "U" cylindrical structure, rather than the open structure of bending or forming the cross beam of the vehicle protection fence. It is an object of the present invention to provide a vehicle protective fence using cross beams having a "U" cross-sectional structure with a large cushioning effect and high impact strength during external impact by the impact.

The present invention is a vehicle protection fence, the cross section between the cross beam 30 having a closed cross-section of the "U" -shaped cylindrical structure, and the support (20) coupled with the cross beam 30, the tab (TAP) with a metal material 31 ) The welding is welded and the bolt 32 is configured to be fastened in the support 20, and the support 20 is characterized in that the front lower end is bent to "L" to increase the lower strength.

Vehicle protection fence using a cross beam having the present invention "U" cross-sectional structure to achieve the object as described above and to remove the drawbacks of the prior art is not a twin structure that the cross beam is bent or formed (forming) It has a "U" cylindrical structure (closed section) to maximize the strength and effectively combines the compressive strength of tensile strength with a metal material, which is resistant to external shocks and the exterior is beautifully plated and coated metal material, and corrosion occurs. It is semi-permanent and easy to install as a prefabricated member because it maintains the initial state as it is.

Referring to the configuration and the operation of the embodiment of the present invention in detail with reference to the accompanying drawings as follows.

1 is a perspective view of a vehicle fence using a cross beam having a "U" cross-sectional structure according to the present invention,

The present invention has a cross-section of the cross beam 30 having a "U" cylindrical structure in the construction of the material for the fence fence device consisting of the support 20, cross beam 30, the base plate 10, The strut 20 is a structure having a lower front portion by bending the lower portion "L".

2 is a left side view of a vehicle protection fence using a crossbeam having a "U" cross-sectional structure according to the present invention,

The present invention is a cross-section "U" -shaped cylindrical structure having a closed cross-section between the cross beam 30, and the support (20) coupled to the cross beam 30, the tab (TAP) processing welded with a metal material 31 and the support ( 20 shows the structure in which the bolt 32 is fastened.

As described above, the tabs are welded between the struts 20 coupled to the inner side of the cross beams 30 with a metal material 31 to have a strong structure, and the nut protrudes by fastening bolts in the direction of the cross beams 30 from the struts 20. There is no aesthetic appearance and easy construction.

Figure 3 is a cross-sectional view of the lower front end of the strut according to the present invention,

The vehicle fence fence strut 20 of the present invention is a structure bent in front of the lower end portion "L". Conventionally, there was a disadvantage in that the cost is increased by coupling another plate in the middle of the base plate 10 and the support 20, and the present invention removes the intermediate plate and the support by bending the front lower end of the support by the letter "L". Can increase the strength and reduce the cost.

The present invention configured as described above has a buffering effect until the outer surface contacts the inner side when the outer vehicle contacts the outer side of the cross beam, so there is no need for a shock absorbing device, and the support interval of the inner side of the cross beam is narrow and the supporting surface is impacted by four places High strength In addition, it is possible to have a sturdy structure by tapping and welding the cross beam side coupled to the support with a thick steel, and there is no nut protruding and only the bolt head is exposed by fastening only the bolt in the support, there is a good aesthetic and easy construction.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

The vehicle protection fence using the horizontal beam having the present invention "U" cross-sectional structure configured as described above is effectively combined with the compressive strength of the tensile strength of the metal material to cushion the outer surface to contact the inner surface when the outer vehicle contact the outer surface of the horizontal beam. There is no need for a shock absorber, and the lower part of the front part of the strut is bent by "L" to raise the lower strength, so there is no need to fasten another plate between the strut and the base plate, resulting in cost reduction and combining with the strut. It has strong structure by tapping and welding the cross beam side with thick steel, and it is strong against external impact because there is no nut protruding by fastening bolts from the support when installing, and the exterior is made of metal material coated and coated. Useful design that is semi-permanent and easy to install as a prefabricated member because it is maintained as it is to be.
