The gaze guide rod 200 is embedded in a buried groove (G) formed on the road surface, an insertion portion 320 having a seating end 322 is formed inside the upper portion, and a coupling end 340 is provided at the center bottom. The formed buried support 300, a hollow tube-shaped fixing part having an inclined surface 522, and an induction rod body 400 fitted to the seating end 322 with the lower end fitted to the insertion portion 320, and 520) is provided with a fixed member 500 seated on the coupling end 340, and a pressing inclined surface 622 inclined at a greater angle than the close inclined surface 522 based on the virtual vertical line is formed on the outer peripheral surface, fastening It comprises a pressing member 600 coupled to the coupling end 340 with the fixing member 500 by the member 700.

This will be described in more detail.

3 to 5, the buried support 300 is buried in the buried groove G formed in the road surface, and an insertion portion 320 having a seating end 322 is formed inside the upper portion, A coupling end 340 is formed at the center bottom. That is, the buried support 300 is made of a cylindrical shape with a bottom, a seating end 322 is provided on the inner upper part, and an inserting part 320 that is opened upward is formed, and the inner floor has a height equal to the height of the seating end 322. The furnace coupling end 340 has a structure formed to protrude. At this time, a through hole 342 for the fastening member 700 to pass through is formed in the center of the coupling end 340, and the insertion part 320 is prevented from being detached when being embedded in the buried groove G formed in the road surface. The outer diameter is formed larger toward the lower portion, and a locking jaw 360 is formed at a lower portion of the outer circumferential surface. As described above, the locking jaw 360 is formed in an annular shape in the lower region of the outer circumferential surface, and the outer circumferential surface of the inserting portion 320 is formed larger toward the locking jaw 360, so that the filling material is filled in the state inserted into the buried groove G. After curing, the outer circumferential surface and the engaging jaw 360 are caught, so that separation may be prevented.

Meanwhile, the seating end 322 and the engaging end 340 are formed at the same height as shown in FIGS. 5 and 6, and when the fixing member 500 is coupled to the buried support 300, the fixing member 500 The bottom center portion is seated on the upper surface of the coupling end 340 and the bottom edge is seated on the upper surface of the seating end 322. At this time, the seating end 322 and the engaging end 340 need not be formed at the same height, the engaging end 340 may be formed lower, or the seating end 322 may be formed lower. However, it is preferable that the seating end 322 and the engaging end 340 are formed at the same height so that the fixing member 500 is stably seated. As the fixing member 500 is seated on the seating end 322 and the coupling end 340 as described above, the guide rod 400 is provided between the inner circumferential surface of the insertion portion 320 and the outer circumferential surface of the fixing portion 520 of the fixing member 500. A fitting groove (S) for fitting the lower end portion is formed.

The fitting groove (S) is narrowed according to the degree of pressing the pressing member 600, because the fixing portion 520 of the pressing member 500 is extended outward by the pressing force of the pressing member 600, This means that the fixing member 520 is fixed by pressing the lower end of the guide rod 400 more strongly.

The buried support 300 may be made of a hard synthetic resin material or a metal material.

The guide rod 400 is formed in a hollow tubular shape, and the lower end is fitted into the insertion portion 320 to be seated at the seating end 322, and is formed of a synthetic resin material, and a reflective tape 450 is attached to the outer circumferential surface. In addition, the guide rod 400 is made of a conical shape to have structural stability, uprightness and self-stiffness. That is, the diameter of the lower portion is formed larger than the diameter of the upper portion. This guide rod 400, as shown in Figure 3, may be composed of a closed cross-section, as shown in Figure 4 (a) and (b), non-closed cross-section or to be formed in a partially closed cross-section Can.

In this embodiment, it will be described based on the guide rod 400 is formed as a non-closed section or a partially closed section.

The guide rod 400 having a non-closed cross-section or a partially closed cross-section, as illustrated in FIGS. 4 to 7, is cut off at the upper region A2 of the rear surface of the guide rod 400 to absorb external force to absorb external force. The absorption opening 420 is formed, and a plurality of deformation induction holes 440 are formed in the middle and lower regions A1 of the rear surface to easily deform when an external force is generated. In addition, the upper end is cut to form an upper opening 430 connected to the external force absorbing opening 420.

As described above, since the opening portion 420 for absorbing external force and the upper opening portion 430 and the deformed induction hole 440 are formed on the rear surface of the induction rod body 400 to have a non-closed section or a partially closed section, the guide rod 400 ) When the external force is applied, it is deformed while absorbing the external force, so damage can be prevented or minimized. That is, the rear portion (upper region) of the guide rod 400 is cut to form an open portion 420 and an upper open portion 430 for absorbing external force, so that they do not have rigidity, so that deformation is easily performed when an external force is applied. Therefore, damage caused by external force can be minimized or prevented. In other words, the gaze guide rod according to the prior art is formed in a hollow cylindrical shape, so it is not easily deformed and easily damaged when an external force is applied. However, the guide rod 400 according to the present invention has an open portion 420 for absorbing external force and a top Since the open portion 430 is formed and does not have rigidity, even when an external force is applied, it is easily deformed and absorbs the external force, thereby minimizing or preventing damage.

In addition, a plurality of deformation guide holes 440 are formed in the rear lower region A1 of the guide rod 400, so that when an external force is applied from the front side to the rear side of the guide rod 400, a plurality of deformation guide holes 440 The lower portion (A1) of the formed rear side is easily deformed by the deforming guide holes 440, and the guide rod 400 is bent toward the rear side. That is, when an external force is applied, the region where each deformation guide hole 440 is formed is easily deformed by each deformation guide hole 440, so that the guide rod 400 can be bent toward the rear side. Therefore, the guide rod 400 is not deformed but damaged even when an external force is applied. In addition, since the opening portion 420 or the deformation guide hole 440 for absorbing external force is not formed in the front portion of the guide rod 400, when the external force is extinguished after being deformed by the external force, a restoring force is generated to restore the original state again. . As described above, since the opening portion 420 for absorbing external force and the deformation inducing hole 440 are formed only on the rear side, deformation to the rear side is easily achieved and is immediately restored upon the disappearance of external force. Therefore, the structure in which the opening portion 420 for absorbing external force and the deformation guide hole 440 are formed only on the rear surface is a factor for improving the durability of the guide rod 400.

The above-described deformation induction hole 440 is formed in the lower region (A1) and the external force absorption opening portion 420 is formed and the range may be variously configured according to the size and shape of the guide rod 400.

The fixing member 500 is for fixing to the buried support 300 by pressing the lower end of the guide rod 400 when the pressing member 600 is pressed, as shown in FIG. 3, an inclined surface in close contact with the inner surface ( The fixing part 520 having 522 is provided in an annular shape and seated on the coupling end 340. The fixing member 500, as shown in Figure 3, through the fastening member 700 is formed in the through-hole for penetrating, and deformed to the outside when the pressing member 600 is pressed, rubber or synthetic resin material Is made of

The fixing member 500 is not shown in the drawing, but may be made of a metal material. In the case of a metal material, an incision is formed in the annular (cylindrical) fixing portion 520 from the top to the bottom. Since the incision is formed by at least one or more numbers at regular intervals, the fixing part 520 may be formed of at least one pressing piece. Due to this structure, when the pressing member 600 moves downward and presses, the upper end of each pressing piece is deformed to the outside, and the inner surface of the lower end of the guide rod 400 is pressed against the inner surface of the insertion portion 320 to be firm. Can be fixed.

The pressing member 600 is intended to expand and deform by pressing the fixing portion 520 of the fixing member 500 to the outside while moving downward (towards the coupling end) by the fastening force of the fastening member 700, a virtual vertical line A pressure inclined surface 622 inclined at a larger angle than the close inclined surface 522 based on (L) is formed on the outer circumferential surface, and coupled to the coupling end 340 together with the fixing member 500 by the fastening member 700 do. The pressing member 600 is made of a metal material or a hard synthetic resin material, and a ring-shaped pressing end 620 is formed at an edge at an oblique inclination upward and outward, and a pressing inclined surface at the outer circumferential surface of the pressing end 620 ( 622) is formed. The pressing inclined surface 622 of the pressing end 620 is for expanding and deforming the fixing portion 520 by pushing it outward. At this time, the diameter of the pressing member 600 is formed to be larger than the inner diameter of the fixing member 500 so that when the pressing member 600 is fastened to the fastening member 700, it moves downward and expands the fastening member 500 to the outside. It can be pressurized. That is, even if the pressing inclined surface 622 is not formed larger than the close contact inclined surface 522, the diameter of the pressing member 600 is formed larger than the diameter of the fixing member 500 can expect the same action.

The gaze guide rod 200 configured as described above, when an external force is applied to the guide rod 400 from the front side as shown in FIG. 7, the lower region A1 of the rear side is easily deformed by the respective deformation guide holes 440 It is not broken, so it is bent toward the rear. However, since the external force applied to the guide rod 400 is absorbed while the lower region A1 in which each deformation guide hole 440 is formed is bent and deformed, the guide rod 400 is not damaged. That is, the guide rod 400 is easily deformed by the open portion 420 for absorbing external force and the deformation guide holes 440, so that it is not damaged even if an external force is applied.

The fastening member 700 is for fixing the lower end of the guide rod 400 by coupling the pressing member 600 and the fixing member 500 to the coupling end 340, and is made of bolts and provided in the buried support 300 It can be fastened to a nut or a fastening hole, or made of a nut to be fastened to a bolt provided on the buried support 300.

The method of constructing the gaze guide rod 200 configured as described above will be described based on FIGS. 3 to 7 and FIG. 8 below.

Among the accompanying drawings, FIGS. 8A and 8B are schematic block diagrams illustrating a method of constructing the gaze guide rod shown in FIG. 3 and schematic block diagrams illustrating a method of replacing the guide rod.

3 to 7 and 8 (a), the construction method for embedding the gaze guide rod 200 according to the present invention on the road surface is as follows.

(a) Gaze guide rod assembly step (S1)

In order to embed the gaze guiding rod 200, the gaze guiding rod 200 is first assembled. That is, the lower end of the guide rod 400 is fitted to the insertion portion 320 of the buried support 300 to be seated at the seating end 322. Subsequently, the fixing member 500 having the fixing portion 520 is mounted on the upper surface of the seating end 322 and the pressing member 600 is mounted on the upper surface of the fixing member 500. When the pressing member 600 is seated on the upper surface of the fixing member 500, the fastening member 700 is fastened to the nut provided on the buried support 300 through the pressing member 600 and the fixing member 500. When the fastening member 700 is fastened to the nut, the pressing member 600 presses downward (toward the coupling end) of the fixing member 500, so that the fixing part 520 is expanded and deformed to the outside, and the guide rod 400 ) The bottom of the insertion portion 320 is fixed to the inner circumference. At this time, the fixing part 520, the pressing inclined surface 622 of the pressing member 600 is expanded and deformed to the outside as pressing the close inclined surface 522, the lower end inner surface of the guide rod 400, the insertion part 320 Strongly in close contact with the inner surface of the guide rod 400 is coupled to the buried support (300).

In this process, the assembly of the buried support 300, the guide rod 400, the pressing member 600 and the fixing member 500 is completed and integrated.

(b) Landfill groove formation step (S2)

When the assembly of the gaze guiding rod 200 is completed through the above-described process, a buried groove G is formed on the road surface on which the gaze guiding rod 200 having been assembled is installed. This operation is to form a buried groove G in a size (diameter and depth) in which the buried support 300 is inserted into the road surface as a coring operation. At this time, the depth of the buried groove (G) is greater than or equal to the height of the buried support (300). This is to prevent the upper end of the insertion portion 320 of the buried support 300 from protruding more than the road surface when the buried support 300 is buried. If, when the upper end of the insertion portion 320 is more protruding than the road surface, because the damage to the tire of the vehicle may interfere with the driving of the vehicle, the depth of the buried groove (G) of the buried support (300) It is desirable to form it deeper or equal to the height.

(c) Filling material filling step (S3)

When the buried groove G is formed on the road surface by the above-described buried groove forming step, the buried support 300 of the gaze guide rod 200, which has been assembled, is inserted into the buried groove G. That is, the gaze guide rod 200 is erected and inserted into the buried groove G. In this process, the buried support 300 is inserted in the erected state in the buried groove (G). Subsequently, the filling material 300 is filled with a filling material in the filling groove G into which the filling support 300 is inserted, and cured to complete the construction of the gaze guide rod 200. Here, the filling material may use a non-shrinkable mortar, but is not limited thereto, and various materials may be applied.

When the filling material is cured by the above-described process, the engaging support 360 of the filling support 300 is caught by the cured filling material, so that the filling support 300 is not separated.

As described above, assembling the gaze guide rod 200 and forming a buried groove G to insert the buried support 300 and then filling the filling material, the reclamation construction of the gaze guide rod 200 is completed. At this time, the construction may be performed by forming a buried groove G first and assembling the gaze guide rod 200.

On the other hand, after the completion of the construction of the gaze guide rod 200, the method for replacing the gaze guide rod 200 in case of damage to the gaze guide rod 200, from among the attached drawings, FIGS. 3 to 7 and 8 ( b).

(d) Pressure release step (S4)

When the guide rod 400 of the gaze guide rod 200 is damaged and needs to be replaced, the pressing member 600 is released by releasing the fastening member 700. When the pressing force of the pressing member 600 is released, since the fixing part 520 is spaced apart from the insertion part 320, the remaining guide rod 400 may be separated from the fitting groove S. When the remaining guide rod 400 is removed through this process, a fitting groove S is secured between the fixing portion 520 and the inner circumferential surface of the insertion portion 320.

(e) A Assembly step (S5)

After performing the aforementioned pressing force release step (S4) to secure the fitting groove (S) wide, the lower end of the new guide rod 400 is secured between the inner circumferential surface of the fixing part 520 and the inserting part 320. It is inserted into (S) and seated on the seating end 322.

f) Replacement completion step (S6)

In the state that the lower end of the guide rod 400 is fitted into the fitting groove S by the above-mentioned provisional assembly step (S5), the upper opening portion 430 and the external force absorbing opening portion 420 of the guide rod 400 are inserted.

At this time, the shape of the opening portion 420 for absorbing external force or the deformation induction hole 440, the formation position, etc. is not limited. That is, the guide rod 400 may have a non-closed section or a partially closed section by forming holes or openings capable of absorbing shock and inducing deformation.

Thus, by forming the opening portion 420 or the deformation guide hole 440 for absorbing external force in the guide rod 400, the guide rod 400 has a non-closed or partially closed cross-section, thereby minimizing damage due to external force. .

That is, when an external force is applied to the induction rod 400, the induction rod body is induced to deform the induction rod body 400 while absorbing the external force (shock) applied by the opening portion 420 or the deformation induction hole 440 for absorbing the external force. 400 is easily deformed. Therefore, damage to the guide rod 400 having a non-closed cross-section or partially closed cross-section can be prevented or minimized.

Particularly, when an opening or a deformed induction hole is formed on the front and rear surfaces of the guide rod 400, the guide rod 400 may correspond to an external force applied from the front or rear, and an opening or a portion of the front and rear and both sides When the deformation guide hole is formed, the guide rod 400 can not only respond to the external force applied from the front and rear sides, but also to the external force applied from the side.

In addition, the guide rod 400 having a non-closed cross-section or a partially closed cross-section as described above is a buried groove G of the road surface by a buried assembly consisting of the above-described buried support 300, a fixing member 500, and a pressing member 600. ), or may be installed on the road surface by an anchor type base member (A). That is, it can be applied to the anchor method or the reclamation method.

At this time, the light emitting means 800 is preferably made of an LED (LED), but is not limited to this, the power source itself is made of a rechargeable battery provided on the solar panel and the buried support 300, etc. provided in the induction rod 400 It may be supplied from a photovoltaic device, or as shown in FIG. 10, an external power source supplied from a street light or a separate external photovoltaic device installed on the roadside may be supplied. 10 illustrates that the light emitting means 800 is supplied with power from the outside by a power supply line 810.

And the light-emitting means 800, as shown in Figure 10, is provided on the upper surface of the pressing member 600 may emit light to illuminate the inner circumferential surface (inner) of the guide rod 400, Figure 11 As shown, the light provided by the buried support 300 can emit light to illuminate the outer circumferential surface (outside) of the guide rod 400. When the light emitting means 800 is provided on the buried support 300, as shown in FIG. 11, the light emitting means 800 may be buried and installed at the upper end of the insertion part 320. Of course, the light emitting means 800 may be installed in a buried assembly at a lower position than the road surface.

On the other hand, the light emitting means 800 may be operated so as to emit a flashing light if necessary by a built-in circuit.

In addition, the light emitting means 800 may be formed in a circular shape. This may cause light emitted to uniformly illuminate the entire inner or outer circumferential surface of the guide rod 400.

As described above, the light emitting means 800 is provided on the upper surface of the pressing member 600 or the buried assembly including the pressing member 600, and is positioned lower than or equal to the road surface, thereby being driven by the vehicle or by pedestrians. It is not damaged by the generated external force. Therefore, the maintenance cost of the light emitting means 800 can be significantly reduced.

In addition, since the light emitting means 800 is provided inside the buried support 300, the light emitting means 800 is not damaged even if the guide rod 400 is damaged.

Meanwhile, FIG. 12 shows an example of the gaze guide rod 200 to which the light emitting means 800 is applied. As illustrated in FIG. 12, when power is supplied while the light emitting means 800 is provided in the buried assembly, light emitted from the light emitting means 800 illuminates the inner circumferential surface of the induction rod 400. Accordingly, since the entire guide rod 400 made of an orange or yellow-based synthetic resin material is brightly illuminated by the light of the light emitting means 800, visibility, which can give attention to drivers or pedestrians at night as well as during the day, is significantly improved.
