  The present invention provides a base portion fixed to the installation surface, a marker column main body portion placed on the base portion, and a flange formed at a lower portion of the marker column main body portion. The present invention relates to a road sign post provided with a ring-shaped fixing member for fixing.

  Such road sign pillars are installed on roads and sidewalks, and are used as signs for preventing intrusion of automobiles (for example, Patent Document 1 below). FIG. 4 shows a general attachment structure when attaching such a road sign post to an installation surface such as a road or a sidewalk. In FIG. 4, the lower left half is a cross-sectional view, and the other part is an external view.

  The road sign pillar A includes a base part 100 fixed to the installation surface B, a sign post main part 101 placed on the base part 100, and the sign post main part 101 as a base part 100. And a ring-shaped fixing member 102 for fixing. A reflection sheet 103 is wound around and fixed to the outer periphery of the sign post body 101 so that the road sign post A can be easily recognized at night. A flange 101 a is formed in the lower part of the sign post body 101, and the flange 101 a is fixed so as to be pressed by a fixing member 102. The fixing member 102 is fixed by fastening with a bolt 104 from the installation surface B side of the base part 100. The reason why the bolt 104 is coupled from the installation surface B side is to prevent the bolt 104 from being seen from the outside.

  An anchor 105 is embedded in the ground, and the road sign pillar A is fixed to the installation surface B by an anchor bolt 106 provided at the center of the base 100. Further, as a method of fixing the road sign pillar A to the installation surface B, in addition to the method shown in FIG. 4, anchor bolts are embedded in the installation surface B with the tip protruding, and provided on the bottom surface of the base portion 100. There is a method of screwing the formed nut to the tip of the anchor bolt (hole-in anchor type). Furthermore, there is also a method of bonding the bottom surface of the base part 100 to the installation surface B with an adhesive without using anchor bolts (adhesive type).

  In such a case, the sign post body 101 has a large area exposed to the outside, and is often damaged due to collision of a car or a bicycle. In that case, it is necessary to replace the sign post body 101 with a new one. However, in the case of the mounting structure of FIG. 4, it is necessary to release the coupling by the bolt 104 in order to remove the sign post main body 101. For this purpose, it is necessary to remove the entire road sign post A from the anchor 105. Therefore, a jig for rotating the road sign pillar A around the axis of the anchor bolt 106 is also necessary, and the maintenance work is troublesome. Similarly, in the case of the hole-in anchor type, it is necessary to remove the entire road sign post A from the anchor bolt. In the case of the adhesive type, it is necessary to peel off the entire road sign post A from the installation surface B. Furthermore, since the installation surface B on which the base unit 100 is fixed is in a low place, there is also a problem that the replacement work is difficult.

  This invention is made | formed in view of the said situation, The subject is providing the road sign pillar which can shorten the working time at the time of replacing | exchanging a sign pillar main-body part.

In order to solve the above problems, the road sign pillar according to the present invention is:
A base fixed to the installation surface;
A sign post body placed on the base,
A ring-shaped fixing member for fixing a flange formed at the lower part of the sign post main body part to the base part, and a road sign post comprising:
A first through hole in the vertical direction is formed in the fixing member, a second through hole in the vertical direction is formed in the flange, and a nut is embedded in the upper surface of the base part.
In a state where the flange is positioned at a predetermined fixing position of the base portion by a positioning mechanism provided between the marker column main body portion and the base portion, the bolt is first above the fixing member. The through hole and the second through hole are inserted and screwed into the nut.

  The effect of the road sign pillar by this structure is demonstrated. A flange is formed in the lower part of the sign post body part, and the sign post body part is fixed to the base part by fixing the flange to the base part by a fixing member. A first through hole and a second through hole are formed in the fixing member and the flange, respectively, and a nut is embedded in the upper surface of the base portion, so that the bolt is inserted from above the fixing member into the first through hole and the second through hole. The flange can be fixed to the base portion by the fixing member by screwing into the nut of the base portion through the hole. At this time, the road sign post of the present invention can position the flange at a predetermined fixed position of the base portion by the positioning mechanism, so that the second through hole of the flange and the nut of the base portion can be easily aligned. be able to.

  On the other hand, when replacing the sign post main body, the fixing of the flange by the fixing member can be released by removing the bolt from above, and the sign post main body can be removed from the base. In this case, since the base part may remain fixed to the installation surface, the work time when the sign post body part is replaced can be shortened. In addition, when attaching a new sign post body part, for example, even if the installation surface where the base part is fixed is low, the position of the second through-hole of the flange and the nut of the base part is determined by the positioning mechanism described above. Therefore, the marker column main body can be easily fixed to the base. As a result, it is possible to provide a road sign post that can shorten the work time when exchanging the sign post main body.

  In the road marking pillar of the present invention, it is preferable that the positioning mechanism is configured by the nut having a tip projecting from the upper surface of the base portion and the second through hole into which the tip is fitted. .

  According to this configuration, since the second through hole of the flange is fitted to the tip of the nut of the base part, the position of the second through hole and the nut can be easily adjusted. It can be easily fixed at a predetermined fixing position of the base part. Furthermore, since the positioning mechanism can be configured without adding a new member, the cost can be reduced.

  In the road marking pillar of the present invention, it is preferable that the nut is an insert nut embedded in a recess provided on an upper surface of the base portion.

  According to this configuration, the nut can be easily embedded in the upper surface of the base portion, and further, the insert nut longer than the depth of the concave portion is embedded in the concave portion, so that the tip end portion of the nut can be embedded in the upper surface of the base portion. It is also easy to protrude from.
