JP 2010-168897 A

  In FIG. 4 and the like of Patent Document 1, an anchor member 9 is inserted into a hole excavated on the road surface R and embedded with an adhesive 8 such as an epoxy resin adhesive, and the base 2 is embedded in the embedded anchor member 9. A configuration is shown in which a road sign post A is fixedly installed on a road surface R in a vertical standing posture by screwing a bolt 5 protruding downward. However, when an excessive force is applied to the road sign pillar A or when the road surface R or the adhesive 8 is deteriorated, the road surface R or the adhesive 8 is destroyed and the anchor member 9 is moved into the hole of the road surface R. There is concern about the possibility that the road sign pillar A will fall down.

  Therefore, the present invention provides an installation structure in which an anchor nut to which an anchor bolt of a marker pillar is screwed is difficult to be removed from a buried hole.

In order to achieve the above object, the present invention is configured as follows.
In other words, the sign post installation structure according to the present invention includes an anchor nut that is housed in an embedding hole formed in the upper surface of the base and is embedded in the base with a fixing material filled in the embedding hole. It is an installation structure of a marker pillar that is erected by a male screw of an anchor bolt part protruding downward,
Between the base upper surface and the base, a base member formed separately from the base is disposed and installed on the base upper surface,
The pedestal member includes a through hole through which the male screw of the anchor bolt portion can be inserted, and a fixing portion fixed to the upper surface of the base, and the fixing portion is fixed to the upper surface of the base on the side of the embedded hole. The member is installed on the upper surface of the base, and the anchor bolt portion inserted into the through hole of the pedestal member is screwed to the anchor nut in the embedded hole, so that the marker column is erected above the pedestal member. It is characterized by that.

According to the installation structure of the marker column according to the present invention, the anchor bolt portion protruded downward from the lower surface of the marker column base to the anchor nut embedded and fixed by the fixing material filled in the embedded hole drilled in the upper surface of the base. Since the marker column is erected by screwing the male screw, the marker column can be easily removed and repaired or replaced by removing the anchor bolt portion from the anchor nut.
Further, a base member formed separately from the base is disposed between the base upper surface and the base, and the male screw of the anchor bolt portion inserted through the through hole of the base member is screwed into the anchor nut. Since the sign pillar is erected above the pedestal member, the pedestal member does not become an obstacle to the work of installing or removing the sign pillar and can be used easily.
Further, since the fixing portion of the pedestal member is fixed to the upper surface of the base on the side of the buried hole and the pedestal member is installed on the upper surface of the base, an excessive force is exerted on the marker pillar standing above the pedestal member In such a case, the force transmitted to the anchor nut in the buried hole is dispersed and reduced by the fixing portion of the base member, so that the fixing material filled in the buried hole and the base around the buried hole are destroyed. This makes it difficult for the anchor nut to come out of the buried hole.

  In addition, if the fixing portion of the pedestal member is disposed at least directly below the outer edge of the base or outward from the outer edge of the base, an excessively large marker column is provided above the pedestal member. In the case where a force is applied, the force transmitted to the anchor nut in the previous buried hole is more efficiently distributed to the fixing portion of the pedestal member and is further reduced, so the anchor nut is less likely to be removed from the buried hole. preferable.

  Further, if the fixed portion of the pedestal member is formed in a wedge shape, the fixed portion is inserted into the base from above, and the base member is installed on the top surface of the base, the base member can be easily placed on the top surface of the base. It is preferable because the anchor nut can be prevented from being pulled out from the buried hole.

  Further, if the adhesive applied to the lower surface of the pedestal member is used as the fixing portion and the pedestal member is bonded and fixed to the upper surface of the base, the pedestal member can be easily installed on the upper surface of the base, and the anchor nut is embedded. Since it is possible to suppress the removal from the hole, it is preferable.

  According to the marker column installation structure of the present invention, the anchor nut to which the anchor bolt is screwed can be prevented from being pulled out from the buried hole, and the marker column standing state can be maintained.

A circular through hole 22 is formed in the center of the base member 2.
The through hole 22 is formed in a size that allows the male screw 16a of the anchor bolt portion 16 of the marker column 1 to be inserted, and is formed in a size that allows the convex portion 14 of the marker column 1 to be inserted.
Further, the through hole 22 is formed in a size that the anchor nut 3 cannot be inserted. Specifically, the through hole 22 is formed to have a size smaller than the planar shape of the anchor nut 3, and more specifically, outside the upper end of the anchor nut 3 formed in a substantially cylindrical shape opening upward. The inner diameter is smaller than the diameter.

The pedestal member 2 is formed with a fixing portion 21 for fixing to the base upper surface 5a.
The fixing portion 21 is composed of an adhesive layer applied to the lower surface of the pedestal member 2, and is formed over the entire lower surface of the pedestal member 2.
The pedestal member 2 is provided so as to be attached to the base 5 by bonding and fixing the fixing portion 21 to the base upper surface 5a.

As shown in FIG. 5, by placing the base member 2 between the base 5 and the base 13 and fixing the base member 2 to the base 5, the anchor nut 3 is detached from the base 5 when a large force is applied to the marker column 1. It becomes difficult to pull out.
Specifically, when a large force is applied to the marker column 1 and a force for pulling the anchor nut 3 upward is applied, the upper end of the anchor nut 3 or the upper surface of the fixing member F that contacts the lower surface of the pedestal member 2 is applied. The force is transmitted to the pedestal member 2. And since the upward force transmitted to the base member 2 is distributed to the base 5 via the fixing plate 21a that fixes the base member 2 to the base upper surface 5a and the fixing part 21 composed of the anchor body 21b, The force is less likely to concentrate near the anchor nut 3, and the destruction of the fixing material F near the anchor nut 3 and the destruction of the base 5 near the buried hole H are suppressed.
Moreover, as shown in FIG. 5, since the said fixing | fixed part 21 of the base member 2 is arrange | positioned further outward than the outer edge of the base 13 of the marker pillar 1, a big force is applied to the marker pillar 1, and the anchor nut 3 is attached. When a force for pulling upward is applied, the force transmitted to the base member 2 and dispersed to the foundation 5 through the fixing portion 21 is dispersed to the base 5 at a position further away from the buried hole H. For this reason, the force to concentrate on the vicinity of the anchor nut 3 arranged just below the center of the base 13 can be more efficiently dispersed. Therefore, the fixing material F near the anchor nut 3 can be broken or buried holes H can be broken. The destruction of the nearby substrate 5 can be suppressed.

  In addition, the installation structure of the marker pillar which concerns on this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

  For example, the base member 2 shown in FIG. 6 has the anchor body 21b of the fixing portion 21 formed separately from the fixing plate portion 21a, but is not limited thereto. For example, the anchor body 21b may be integrated with the fixed plate portion 21a and formed on the pedestal member 2 so that the wedge portion 26 inserted into the base 5 can be inserted without rotating.

  Further, the pedestal member 2 shown in FIG. 6 is formed with two fixing plate portions 21a of the fixing portion 21, but is not limited to this, and may be formed with three or more. When a plurality of the fixed plate portions 21a are formed on the outer edge of the pedestal member 2, the anchor plate 21b attached to the specific fixed plate portion 21a is provided by being arranged at equal intervals in the circumferential direction as shown in FIG. This is preferable because the force applied to the marker column 1 is less likely to concentrate.

  Further, the pedestal member 2 shown in FIG. 2 is formed in a circular plate shape having the same size as the outer diameter of the lower surface of the base 13 of the marker column 1, but is not limited to this, and the anchor nut 3 is fixedly embedded.
