Reference numeral 1 denotes a post such as a car stop that is erected on an installation surface G according to the present invention, and a tubular body 2 that is embedded in an installation surface G, which will be described later, and an erection on the installation surface G through the tubular body 2 The support column body 11 is provided. The column main body 11 includes a pole portion 12 and a base portion 13 disposed below the pole portion 12, and a bolt B projects from the bottom surface 14 of the column main body 11.

  The column main body 11 is an elastically deformable cylinder (in this embodiment, an elastically deformable cylinder), and is made of an elastically deformable synthetic resin material such as polyurethane synthetic resin, silicon resin, or elastomer. With this configuration, the column main body 11 is configured to bend when a strong external force such as a collision of a vehicle or bicycle or a stepping on a person is applied, and to be restored to its original state by its elasticity when the external force is removed. . In addition, the support | pillar 1 may be a thing which can be elastically deformed, and may be formed with a metal and cannot be elastically deformed.

  On the outer periphery of the base portion 13, a band-like reflector R in which spherical glass beads are embedded in a synthetic resin is fitted and attached to a groove formed in the base portion 13.

  Reference numeral 2 denotes a tubular body embedded substantially flush with the installation surface G, and a bolt B suspended from a columnar leg portion 15 projecting from the bottom surface 14 of the column body 11 on the tubular body 2. An upper surface plate 22 having a circular through hole 21 through which is inserted is attached, and a support portion 24 having a female screw portion 23 is provided below the upper surface plate 22, and the female screw portion 23. The column B is screwed into the column 1 and the column 1 is erected on the installation surface G. The support portion 24 is formed in a U-shape opening upward and is attached to the lower surface of the upper surface plate 22. A hole 242 is formed in the bottom plate portion 241 of the support portion 24, and a female screw is cut into the inner peripheral surface of the hole 242 to form a female screw portion 23.

  When the support column 1 is installed on the installation surface G, the insertion hole 3 having a diameter smaller than the outer diameter of the upper surface plate 22 is dug up at the installation location, and the bolt B protruding from the bottom surface 14 of the support column body 11 as shown in FIG. The tubular body 2 is preliminarily attached to the bottom surface 14 of the column main body 11 by screwing into the female screw portion 23, and then the tubular body 2 is substantially faced to the installation surface G in the insertion hole 3 formed in the installation surface G. By embedding and fixing in one, the construction of the support column 1 is completed. As shown in FIG. 3, if the insertion hole 3 is dug up to form the insertion hole 3, the mortar M is poured into the insertion hole 3, and the tubular body 2 is inserted into the insertion hole 3, the installation surface G is more firmly formed. The support 1 can be erected and is preferable.

  Further, as shown in FIG. 4, an insertion hole 3 having a diameter smaller than the outer diameter of the upper surface plate 22 is dug up at the installation location, and the tubular body 2 is first substantially flush with the installation surface G in the insertion hole 3 formed in the installation surface G.

The support column 1 may be erected on the surface G.

  As shown in FIG. 1 (a), the through hole 21 formed in the upper surface plate 22 of the tubular body 2 has a slightly larger diameter than the leg portion 15 of the support column 1 and is erected on the installation surface G. When an external force is applied to the support column 1 and elastically deformed, the side surface of the leg portion 15 comes into contact with the inner peripheral surface of the through hole 21 to prevent the support column 1 from being extremely tilted.

  Thus, the bolt B projecting from the bottom surface 14 of the support column 1 is screwed into the female screw portion 23 of the tubular body 2 embedded substantially flush with the installation surface G, and the support column 1 is set up on the installation surface G. By installing, it is possible to stand the column 1 on the installation surface that cannot be constructed using an adhesive, and it is not necessary to cure the adhesive, so the construction period of the column 1 is shortened. In addition, it is easy to attach and detach the support column 1.

  In this embodiment, the tubular body 2 is directly embedded in the installation surface G and the support column 1 is erected. However, the present invention is not particularly limited to this configuration, and a so-called concrete foundation block is used. The support column 1 may be installed. That is, a foundation block having an insertion hole formed in the center in the longitudinal direction is embedded substantially flush with the installation surface G, and there is a gap between the inner circumferential surface of the foundation block and the outer circumferential surface of the tubular body 2. In this case, the gap is filled with mortar M or the like, the tubular body 2 attached to the lower portion of the support column 1 is inserted into the insertion hole 3, the support column 1 is erected on the installation surface G, and the mortar M is dried. You may make it solidify and finish the construction of the support | pillar 1. FIG.
