Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

3 is an enlarged view of the portion "A" of FIG. 3, and FIG. 5 is a cross-sectional view of the portion "B" of FIG. 3 And FIG. 6 is a view schematically showing an operating state of the shock absorber according to an embodiment of the present invention.

An anti-rocking device according to an embodiment of the present invention is installed at a boundary portion between an inclined plane 10 and a road 20 so as to prevent falling of an inclined plane 10 and comprises a strut beam 100, (200), and support reinforcing wire rope (300).

The beam 100 is formed in the form of a beam such as an I beam or an H beam and is installed perpendicularly to the foundation structure 30 provided at the boundary between the slope 10 and the road 20. The foundation structure 30 may be formed of a concrete structure and is formed long along the edge of the road 20. A plurality of the straddle beams 100 are installed so as to be spaced apart from each other at regular intervals along the road direction.

The blocking wire ropes 200 are installed between the adjacent stanchion beams 100 to connect adjacent stanchion beams 100. The blocking wire ropes 200 are installed in a horizontal direction and a plurality of the blocking wire ropes 200 are vertically spaced from each other. A blocking wire 210 (see FIG. 1) is coupled to the plurality of blocking wire ropes 200 so that the blocking wire 210 together with the blocking wire ropes 200 blocks the falling of the slopes.

The support reinforcing wire rope 300 is installed to reinforce the supporting force of the pillar beam 100. As shown in Fig. 3, one end is connected to the upper end of the pillar beam 100, and the other end is fixed to the slope 10 . The method of fixing the other end of the support reinforcing wire rope 300 to the inclined surface 10 may be performed by inserting the anchor pin 500 into the inclined surface. One end of the support reinforcing wire rope 300 may be connected to the upper end of the strut beam 100 in a variety of ways using a separate fastener 110. At this time, the fastener 110 can be applied as a U-bolt. When the separate fastener 110 such as a U-bolt is used, the fastener 110 is inserted into the holding beam 100 of the existing anti- Reinforced wire rope 300 can be additionally provided. Thus, it is possible to enhance the supporting force by simply adding the support reinforcing wire rope 300 without replacing the existing anti-rocking device.

3 (a), the support reinforcing wire rope 300 is connected to one of the support beam 100 and the support reinforcing wire rope (not shown) extending in the biaxial direction by using one fastener 110 300). Reinforced wire rope 300 extending in the biaxial direction is combined with the support beam 100 so that the two support reinforcing wire ropes 300 are combined with one strut beam 100, Can be further strengthened. The support reinforcing wire rope 300 may also be combined with one support beam 100 as shown in FIG. 3 (b), in which case, 110 is constructed in such a manner that the end of the support reinforcing wire rope 300 is engaged with the fastener 110 to form a fastener ring structure and fastened by another frictional fastener UB . In such a coupling method, since the support reinforcing wire rope 300 is kept in a fixed state by frictional force in a state in which the support reinforcing wire rope 300 is in tight contact with the frictional coupling member UB at the portion where the engagement ring structure is formed, The external impact can be absorbed to a certain extent by the frictional force.

According to this structure, the supporting beam 100 of the anti-rocking device according to the embodiment of the present invention is reinforced by the supporting reinforcing wire rope 300 to the falling rock load, and therefore, The supporting beam 100 can be maintained in a stable structure without being deformed or broken even if the impact load is large and thus the slope 10 can be further strengthened.

At this time, the rockfall generated from the inclined plane 10 is applied to the pillar 100 by the dropping velocity. The impact energy due to the rockfall impact is applied to the support beams 100 and the support beams 100 And transmitted to the reinforcing wire rope 300. If the impact energy is transmitted as it is, the support beam 100 and the support reinforcement wire rope 300 may be damaged. Therefore, the support reinforcement wire rope 300 is provided with the impact absorbing part 400 Is formed.

Since the support reinforcing wire rope 300 reinforces the supporting force of the pillar beam 100 by the tension of its installation structure, the impact absorbing portion 400 absorbs impact transmitted to the support reinforcing wire rope 300 in the tension direction Respectively.

For example, as shown in FIG. 5, the impact absorbing portion 400 includes a winding portion 410 formed in such a manner that the support reinforcing wire rope 300 is wound such that the support reinforcing wire rope 300 has a predetermined reference diameter at an intermediate section, And a frictional coupling member 420 which surrounds the support reinforcing wire ropes 300 at the overlapping portions 410 and fixes the wire ropes 300 in tight contact with each other.

The shock absorbing part 400 having such a structure can absorb an impact due to the mutual frictional force between the overlapped portion of the support reinforcing wire rope 300 and the frictional engagement member 420. 6, an external force is transmitted to the support-reinforcing wire rope 300 in the tensioning direction. At this time, the external force is transmitted to the support-reinforcing wire rope 300 in the direction of the tensile force of the frictional coupling member 420 The support reinforcing wire rope 300 slip in the opposite end directions against the frictional force with respect to the take-up portion 410 (at this time, the reference diameter of the take- And thus the impact on the external force is temporarily absorbed through the friction resistance process.

Therefore, in the anti-rocking device according to the embodiment of the present invention, the supporting force of the strut beam 100 is strengthened by the supporting reinforcing wire rope 300, and at the same time, the impact absorbing part 400 is formed in the supporting reinforcing wire rope 300 Therefore, it is possible to absorb the rockfall impact, thereby more completely preventing the damage of the beam 100 due to the impact, and thus, the safer rockfall prevention function can be performed.

FIG. 7 is an exemplary view showing various forms of the shock absorber according to an embodiment of the present invention.

The impact absorbing portion 400 formed on the support reinforcing wire rope 300 may be formed to include the winding portion 410 and the friction engaging member 420 as described above, Two or more shock absorbers 400 may be formed in the support reinforcing wire rope 300, and the shock absorbers 400 may have different impact energy sizes. When a plurality of shock energy absorbing portions 400 are formed in different shapes, shock absorption functions are sequentially or simultaneously performed by the shock absorbing portions 400, The function is further enhanced.

For example, two shock absorbing parts 400 may be formed on the support reinforcing wire rope 300 as shown in FIG. 7. First, as shown in FIG. 7 (a) Two winding sections 410a and 410b having different reference diameters may be formed in the first and second winding sections 300 and 300, respectively. In the case where two winding sections 410a and 410b having different reference diameters, that is, the first winding section 410a and the second winding section 410b, are formed as described above, an external shock is applied to the support reinforcing wire rope 300 The frictional resistance slip movement occurs in such a manner that the reference diameters of the first and second winding portions 410a and 410b are simultaneously reduced. As the process proceeds, the reference diameter of the first winding portion 410a becomes smaller than the reduction limit The frictional resistance slip movement continues to occur in such a manner that the reference diameter of the second winding part 410b is reduced. In this manner, the shock absorbing function is continuously and sequentially exhibited in this manner.

7 (b), the impact-absorbing portion 400 is formed in such a manner that two winding portions 410a and 410b having the same reference diameter at different positions in the support-reinforcing wire rope 300 are formed . At this time, the tight fitting forces of the friction engagement members 420 in the respective winding sections 410a and 410b, i.e., the first winding section 410a and the second winding section 410b, are different from each other. That is, the magnitudes of the frictional forces generated in the respective winding portions 410a and 410b are formed to be different from each other. In this case, for example, when the magnitude of the frictional force generated in the second winding part 410b is larger than the magnitude of the frictional force generated in the first winding part 410a, an external shock is applied to the supporting reinforcing wire rope 300 The frictional resistance slip movement occurs in such a manner that the reference diameter of the first winding section 410a having a small frictional force is small, and as the process proceeds, the reference diameter of the first winding section 410a is reduced When the limit point is reached, thereafter, the frictional resistance slip movement continues to occur in such a manner that the reference diameter of the second takeup portion 410b is reduced. The shock absorbing function is successively achieved through the sequential frictional resistance slip movement.

8 is a view schematically showing a structure of a strength reinforcing means according to an embodiment of the present invention.

In the strut beam 100 according to an embodiment of the present invention, an intensity reinforcing unit 600 is installed in an intermediate region of the strut beam 100 to reinforce the bending strength of the strut beam 100 with respect to a fall load.

The above-described support reinforcing wire rope 300 reinforces the supporting beams of the pillar beams 100 and at the same time absorbs the impact of the pillar beams to complement the pillar beams 100. The reinforcing wire ropes 300, 600 reinforce the bending strength of the pillar beam 100 to compensate for the stiffness of the pillar beam 100 itself due to the fall impact and load.

The strength reinforcing means 600 includes a strength reinforcing wire rope 610 having both ends connected to the upper and lower ends of one side of the side surface of the strut beam 100 facing the sloping surface 10 and the strength reinforcing wire rope 610, And a support member 620 protruding from the middle portion of one side of the strut beam 100 so as to support the stop portion of the strut beam 100.

According to this structure, if a rockfall occurs from the inclined plane 10 and a downfalling load acts on the beam 100, as shown in FIG. 2, the beam 100 receives a bending load bent in the direction of the road 20 At this time, in addition to the support beam 100 being supported through the support reinforcing wire rope 300, an opposite support force against the bending load on the road 20 side is generated due to the tension of the strength reinforcement wire rope 610, The bending strength of the beam 100 is reinforced.

At this time, the strength reinforcing wire rope 610 may be configured to be loose so that tension is generated only when a dropping impact occurs, but it may be configured to have a tension of a constant size at all times. Also, the tension of the strength reinforcing wire rope 610 may be configured to be adjusted according to the user's need, which may be configured in such a way as to adjust the projecting height of the support member 620.

The method of adjusting the protrusion height of the support member 620 can be configured in various ways through various mechanical elements such as using a mechanical element in which the support member 620 linearly moves according to a user's rotation operation.
