Abstract
A structure of a sign pole is provided. The sign pole includes a tubular member that has a predetermined outer diameter, a predetermined inner diameter, and a predetermined thickness. In a state in which the sign pole is embedded in a ground, the sign pole includes a reinforcement portion having a thickness different from the predetermined thickness while maintaining the predetermined outer diameter in a first range from a first position equal to or lower than a level of a ground surface to a second position located a predetermined distance above the level of the ground surface. The reinforcement portion has a thickness larger than the predetermined thickness.
Claims9
A structure of a sign pole used in a state planted on a ground in an upright state, comprising:
- a sign pole which is formed by a tubular member having a first outer diameter, a first inner diameter, and a first thickness, the first outer diameter having a substantially constant value;
- and
- a flange portion which is formed outside of an outer periphery of the sign pole,
- wherein the sign pole includes a first thick portion having a second thickness larger than the first thickness while maintaining the first outer diameter in a first range from a first position near a level of a ground surface to a second position located a predetermined distance above the level of the ground surface, and
- wherein the sign pole includes a portion that has a thickness gradually decreasing in an upward direction from a thickness of the second position to the first thickness in a position above the second position.
