Description

Eye guide rod and its construction method

The present invention relates to a gaze induction rod and a construction method thereof, and more particularly, to a construction method of a gaze induction rod using a gaze induction rod and an auxiliary rod, which can be constructed without a bolt by a hollow inside and a bushing inserted in the insertion part. it's about

In general, gaze guide rods are installed for the purpose of spatially separating traffic flows in the same and opposite directions by assisting road markings in places where the driver's attention is significantly required, such as places with high risk of traffic accidents, and to foretell dangerous sections. For this purpose, it refers to facilities that can induce the driver's gaze.

These gaze guide rods are installed for the purposes of lane guidance and regulation, sidewalk and lane separation markings, safety zone markings, crosswalk markings, separation zone collision prevention, etc. It is installed in a place where movement to the lane is frequent to block illegal U-turns, and is installed for the purpose of regulating entry into the opposite lane in a place with a large turning radius or a high risk of an accident.

The conventional gaze induction rod, Republic of Korea Patent No. 20-0432648, is easily bent by an external force. Such an induction rod is mainly made of a soft material, and returns to its original position even when bent with elasticity. However, a strong external force, such as a traffic accident, easily breaks the guide rod, and in severe cases, the fixing bolt attached to the base is pulled out together or the base is torn and the gaze guide rod collapses.

In this way, when the fixing bolt coupled to the base of the gaze guide rod is pulled out, the gaze guide rod cannot be reinstalled in the same position due to the bolt marks remaining on the ground, and the problem of having to re-pave the ground is caused.

Therefore, it is possible to prevent or minimize the breakage of the holding rod, even if the holding rod is broken, it is necessary to develop a gaze induction rod having a configuration that can be easily replaced without damage to the ground.

In order to solve the above problems, the present invention is to provide a gaze induction rod and a construction method thereof, which can be constructed without bolts to prevent or minimize damage to the gaze induction rod and the ground.

In order to solve the above problems, the gaze guide rod according to the first embodiment of the present invention is a body portion formed in a cylindrical shape having a hollow interior and a length; one or more reflecting plates formed along the outer circumferential surface of the body portion; a locking part inclined downwardly at the lower end of the body part; It may include an insertion part which is hollow inside and is formed in a cylindrical shape at the lower end of the locking part to be inserted into the ground, and a bushing which is fitted in close contact with the insertion part and is formed in a circular tube shape.

In addition, the gaze guide rod may further include a hole formed in the catching portion for discharging the rainwater introduced into the body portion.

In addition, the bushing, when inserted into the ground, includes a bushing protrusion that helps not to fall out from the ground, the bushing protrusion, one or more may be characterized in that formed on the outer surface of the bushing.

In addition, the gaze induction rod further includes an auxiliary rod, which is a tool used when installing the gaze induction rod on the ground, and the auxiliary rod, in a state overlapped with the gaze induction rod, has a lower end caught in the locking part, and the locking part It may be characterized in that the gaze induction rod is installed on the ground by hitting repeatedly.

In addition, the body portion includes a protrusion that can be used when disassembling the gaze guide rod installed on the ground from the ground, and the protrusion includes a housing formed on the inner surface of the body portion; a pressing protrusion that is located inside the housing and that is retractable and retractable so that it protrudes through the body portion when withdrawing; a fixing projection formed on the pressing projection to be fixed to the housing when the pressing projection is drawn in and out; It may include a moving hole formed in the housing in the form of an 'L' shape in which the pressing protrusion, an elastic member positioned inside the housing, and the fixing protrusion can move as the pressing protrusion is drawn in and out.

In addition, the auxiliary rod may include a dismantling hole formed in a 'L' shape at the lower end of the auxiliary rod so that when the gaze guide rod is dismantled from the ground, the pulled out pressing protrusion can be located.

In addition, the body part includes an external thread formed upwardly at the lower end, and the locking part includes an internal thread on the internal surface so as to be coupled to the external thread, characterized in that it can move along the external thread. have.

The protrusion 150 is a configuration that can be used when dismantling the gaze guide rod 10 installed on the ground G from the ground G, and includes a housing 155, a pressing protrusion 151, a fixing protrusion 152, and an elastic member. It may include a 154 and a moving hole 120 .

The housing 155 is formed in a cylindrical shape on the inner surface of the body 110, and the pressing protrusion 151 is located inside the housing 155, and can be drawn in and out. can protrude.

The fixing protrusion 152 is formed on the pressing projection 151 so that it can be fixed to the housing 155 when the pressing projection is drawn in and out, and the elastic member 154 is formed between the pressing projection 151 and the housing 155 . It is located inside and may have a property of being compressed when the pressing protrusion 151 is drawn in, and returned when it is withdrawn.

The moving hole 120 is a hole formed so that the fixing protrusion 152 can move as the pressing protrusion 151 is drawn in and out, and is most preferably formed in the shape of an 'L' in the housing 155, but is not limited thereto. does not

To describe the operation of the protrusion 150 in detail, when the pressing protrusion 151 protruding from the outer surface of the body 110 is pressed, the elastic member 154 is compressed while the fixing protrusion 152 moves through the moving hole 120 . When moving inward along and rotating to the left in a pressed state, the pressing protrusion 151 moves to the left along the moving hole 120 so that the pressing protrusion 151 is fixed in a retracted state. can

Conversely, when withdrawing the retracted pressing protrusion 151 , the elastic member 154 is returned after the pressing protrusion 151 is rotated to the right to move the fixing protrusion 152 to the right along the moving hole 120 . Accordingly, the pressing protrusion 151 may be withdrawn.

In this way, the auxiliary rod 20 may include a dismantling hole 120 so that the protrusion 150 can be used when the gaze guide rod 10 is disassembled from the ground (G).

Referring to FIG. 7 , the dismantling hole 120 has a 'L' shape at the lower end of the auxiliary rod 20 so that when the gaze guide rod 10 is dismantled from the ground (G), the withdrawn pressing protrusion 151 can be located. can be formed in the form.

Accordingly, when dismantling the gaze guide rod 10 from the ground (G), the pressing protrusion 151 is drawn out and then moved along the dismantling hole 120 to be positioned, and the auxiliary rod 20 is applied upward by force. The gaze guide rod 10 may be dismantled from the ground (G).

8 to 10 , the body part 110 according to the first embodiment of the present invention may include an external thread 192 , and the locking part 130 may include an internal thread 191 .

The outer thread 192 is a screw thread formed upwardly at the lower end of the body part 110 , and the inner thread 191 is a thread formed on the inner surface of the engaging part 130 , and the engaging part 130 moves along the external thread 192 . can

Accordingly, when it is necessary to adjust the height of the gaze guide rod 10, it can be adjusted by moving the locking part 130 to the left and right by moving it along the external screw thread 192, and as the locking part 130 moves, the bushing ( 30) can also be moved together.

11 is an exemplary view illustrating the operation of the length extension part of the gaze induction rod according to the second embodiment of the present invention, and FIG. 12 is an enlarged view of the length extension part of FIG. 11 .

11 to 12, the body portion of the gaze induction rod according to the second embodiment of the present invention may include a length extension.
