10. With the mounting member attached to the mounting portion, it is temporarily fixed to the support column body using screws. The support column according to claim 1.
11. A method for fixing a support column according to claim 1 to the ground or floor surface, The support column body is placed in a recess formed in the ground or floor surface, With the mounting member attached to each of the two or more mounting portions, the inclination of the support column body relative to the ground or floor surface is adjusted by supporting the support column body with respect to the ground or floor surface using the adjustment member. The support column is fixed to the ground or floor surface by filling the recess with a filler and allowing it to harden. How to fix the pillar.

Description

This invention relates to a support column and a method for fixing the support column. Traditionally, lighting has been installed in roads and parks. For example, these lights are fixed in place by embedding part of a support pole in the ground, with a light fixture such as an LED (Light Emitting Diode) mounted on top of the pole. Furthermore, it is crucial to prevent the collapse of lighting fixtures installed in roads, parks, and other public spaces due to corrosion or deterioration of their support poles over time. For example, replacing lighting fixtures (or their support poles) that show signs of corrosion or deterioration over time, or replacing them if they are damaged in an accident, are all possible solutions. For example, Patent Document 1 discloses a technique for quickly fixing an existing pole to the ground by cutting it at the base, leaving the base intact, erecting a new pole in the hollow portion of the remaining base, injecting a filler material between the base and the new pole, and then securing the new pole to the ground. Furthermore, Patent Document 2 discloses a technology relating to a pole adjustment fitting for adjusting the axial position of a novel cylindrical structure relative to the ground.

The embodiments of the present invention will be described below with reference to the drawings. The embodiments described below are merely examples of how to implement the present invention and are not intended to limit the scope of the invention. Furthermore, to facilitate understanding of the explanation, the same reference numerals are used for identical components in each drawing whenever possible, and redundant explanations may be omitted. <First Embodiment> Figure 1 shows how a support column 100 according to the first embodiment of the present invention is fixed to the ground. As shown in Figure 1, a support column 10, which was fixed in the ground with a portion buried in it, is cut at the base, and a support column 100 is to be fixed to the remaining portion 11 of the support column 10. The support column 10 was originally fixed in place with a portion buried in the ground, and for example, it was equipped with a light fixture such as an LED at the top, functioning as lighting for roads and parks. The support column 10 is cylindrical, and cables or other equipment may be arranged within its internal space. The support column 100 comprises a support column body 110 and a mounting member 120 (including an adjustment member 130) attached to the support column body 110. It is intended to be replaced, for example, due to deterioration of the support column 10 over time. The support column body 110 is, for example, cylindrical in shape, with an outer diameter smaller than the inner diameter of the support column 10, allowing it to be inserted into the remaining portion 11 of the cut support column 10. Furthermore, cables for lighting may be arranged within the cylindrical internal space of the support column body 110. Since
