Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. Further, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art. The shape and size of elements in the drawings may be exaggerated for clarity.

Hereinafter, a pillar structure for a guardrail according to an embodiment of the present invention will be described in detail with reference to the drawings.

3, the girder structure for guard rails according to an embodiment of the present invention may include a strut 100, a rigid stiffener 200, and a bending guide 300.

The present invention relates to a girder structure for a guardrail installed on a ground G and includes a support 100 in which a lower portion is embedded in the ground G and a stiffener 100 which is inserted into the support 100, The stiffness stiffener 200 is provided so as to reinforce the ground structure H and is provided over the position of the ground surface H. The rigid stiffener 200 is provided to have a relatively small sectional rigidity in the stucture structure, And a folding guide part 300 for guiding the folded guide part 300 to fold.

The pillar 100 is a member provided around the road to prevent the vehicle V and the like from supporting the impact load caused by a collision or the like and preventing the vehicle V from being released to the outside of the road.

3, a guard rail 30 is provided on the upper side of the support 100 to prevent the vehicle V and the like from being released to the outside, and the impact load transmitted to the guard rail 30 Can be transferred to the holding structure.

The pillar structure of the present invention can be embedded in the ground G of the embankment so that the downward inclination is formed toward the outer side of the road.

The rigid stiffener 200 is inserted into the support 100 and reinforces the rigidity of the support 100.

The rigid stiffener 200 may be installed over an upper region and a lower region of the ground surface G of the ground G to reinforce the rigidity of the strut 100. [

3, the rigid stiffener 200 is inserted into the strut 100, and the rigid stiffener 200 is disposed on the upper side and the lower side of the ground 100 with respect to the ground surface H of the ground G on which the struts 100 are buried, As shown in FIG.

When the impact load of the columnar structure is applied by the vehicle V or the like, the columnar structure H may be bent and the vehicle V may be detached from the ground surface H. The rigid stiffener 200 may be provided on the surface H of the columnar structure. It is possible to prevent the pillar structure from bending at the ground surface H and to improve the protection performance of the vehicle V. [

The bending guide portion 300 may be formed in the rigid stiffener 200 and the position of the bending guide portion 300 may be determined according to a heightwise installation position of the rigid stiffener 200 inserted into the support 100. [

Since the bending guide portion 300 is formed on the rigid stiffener 200 as described above, the stiffener 200 can reinforce the stiffener 100 and the rigid stiffener 200 can be stiffened inside the stiffener 100 The installation position of the bending guide 300 can be adjusted at the construction site, thereby improving workability in the field.

The bending guide portion 300 is a portion that absorbs impact energy while strain energy is consumed as plastic energy while the column structure is deformed when an impact load exceeding the elastic limit is applied to the column structure.

The present invention has the effect that the bending guide portion 300 is formed in the column structure and the impact load is stepwise supported by the buffering force of the ground G and the bending due to the bending of the column structure.

The bending guide portion 300 may be provided in a heightwise direction of the columnar structural body on which the rigid stiffener 200 is installed and may be embedded in the ground G and have a relatively small sectional rigidity in the columnar structural body.

The bending guide portion 300 is disposed inside the ground G in which the support 100 is embedded and the burying depth of the bending guide portion 300 can be adjusted according to the supporting force of the ground G. [

For example, the bending guide portion 300 may be formed on the rigid stiffener 200 and may be installed in the embedded position of the ground G.

At this time, when the rigid stiffener 200 is inserted into the support 100, the height direction installation position of the rigid stiffener 200 formed with the bending guide 300 inside the support 100 is adjusted, ) Can be adjusted.

The pillar structure supports the impact load primarily by the support force of the ground G within the set first target load, and when the impact load exceeds the first target load, the pillar guidance structure 300 is set The impact load can be secondarily supported while the position is folded.

That is, the impact load applied to the columnar structural body by the impact of the vehicle V or the like is primarily supported by the supporting force of the ground G, and when an impact load exceeding the supporting force of the ground G is applied, The impact load can be buffered and supported by folding the columnar structure.

For example, the impact load can be primarily supported by the supporting force of the ground G including the ground surface H to the bending guide portion 300.

That is, when an impact load exceeding the first target load, which is primarily supported by the supporting force of the ground G, acts, the impact load to the target load is supported by the ground G, And the impact load can be secondarily cushioned and supported while the predetermined position of the bending guide portion 300 is folded by the load.

The rigid stiffener 200 may include a first stiffness enhancing member 210, a second stiffness enhancing member 230, and a connection reinforcing member 250.

The rigid stiffener 200 includes a first rigid reinforcing member 210 formed on an upper region of the rigid stiffener 200 to reinforce the rigidity of the strut 100 and a second rigid reinforcing member 210 formed on the lower region of the rigid stiffener 200 A second rigid reinforcing member 230 for reinforcing the rigidity of the strut 100 and a second rigid reinforcing member 230 connecting between the first rigid reinforcing member 210 and the second rigid reinforcing member 230, The rigid reinforcing member 210 and the connection reinforcing member 250 having a relatively small sectional rigidity as compared with the second rigid reinforcing member 230 can be provided.

The first stiffening member 210 may be installed over the upper region and the lower region with respect to the ground surface H of the ground G. [

The second rigid reinforcing member 230 may be installed at a position embedded in the ground G and may be connected to the first rigid reinforcing member 210 in a state of being separated from the first rigid reinforcing member 210 by the connection reinforcing member 250.

The connection reinforcing member 250 is provided to have a relatively small sectional rigidity as compared with the first rigidity reinforcing member 210 and the second rigidity reinforcing member 230 so that the connection reinforcing member 250 can be easily bent May be formed.

The first stiffness enhancing member 210 may be installed on the upper region and the lower region with respect to the ground surface H and the connection reinforcing member 250 may be installed at a position buried below the ground surface H .

The upper end of the connection reinforcing member 250 may be connected to the lower side of the first rigid reinforcing member 210 and the lower end of the connection reinforcing member 250 may be connected to the upper side of the second rigid reinforcing member 230.

For example, the connection reinforcing member 250 may be formed of the same material as the first and second rigid reinforcing members 210 and 230, but may have a shape having a relatively small second moment of inertia .

The moment of inertia of the cross section indicates the difficulty of bending or bending easily when the bending force acts on the material. The material having a large second moment is strong against bending, The material of the shape is weakened by bending.

At this time, when the impact load generated when the vehicle V or the like is dispatched to the guard rail 30 is applied and the impact load exceeds the set target load, the portion where the connection reinforcing member 250 is disposed is folded, It can be buffered secondarily.

The connection reinforcing member 250 may be made of a material having the same sectional size as the first rigid reinforcing member 210 and the second rigid reinforcing member 230 but having a relatively small bending strength.
