  • the sign post In general, when a car collides with a sign post (not applicable to the present invention) and a large external force (bending moment force) is applied from the outside, the sign post will buckle and bend at a position approximately 10 mm above the ground surface. There are many. Therefore, the cross-section secondary moment of the marker column at a position approximately 10 mm above the ground surface is increased (to increase the strength against the bending moment force) to prevent buckling, and the marker column can bend gently without breaking. It is preferable to configure. When the sign pillar is gently bent, it can be restored relatively easily to the original upright state by a sign raising machine or the like.
  • the sign post when a sign post (not applicable to the present invention) buckles at a position approximately 10 mm above the ground surface, the sign post may have wrinkles along the horizontal direction (horizontal direction). This wrinkle is caused by the depression of the marker column in the inner direction (the direction of the center of the circular cross section).
  • the thickness of the marker column is increased at a position approximately 10 mm above the ground surface, or if another reinforcing member (reinforcing member) inside the marker note is disposed, the marker column is less likely to be recessed inward. As a result, wrinkles are less likely to occur. That is, buckling is difficult to occur at this position.

Even when a car collides with a sign post (not applicable to the present invention) and a large external force (bending moment force) is applied from the outside, a predetermined distance L at which the sign post does not buckle and bend is defined as Lmax. .

  • ⁇ Effective buckling length (0.7 when the lower end is completely fixed and the upper end pin is supported)
  • E Young's modulus
  • ⁇ Y Yield stress
  • Lmax depends on the thickness t of the marker column and does not depend on the outer diameter of the marker column. Therefore, it can be seen that the local buckling accompanied by plastic deformation can be substantially prevented by increasing the thickness of the marker column at a position below Lmax from the ground surface.
  • the weight of the sign post can be reduced by setting the range where the thickness of the sign post is large to Lmax or less from the ground surface.

  • Lmax is 120.9 mm.
  • Lmax is 138.2 mm.
  • the outer diameter of the marker column 2 is constant and has a simple cylindrical shape in appearance. Therefore, no extra space is required at the place where the sign post 2 is installed. It is possible to select an installation location with a high degree of freedom in the same way as a general sign post. In addition, even after the sign post 2 is installed, there are no members that obstruct the passage when a passerby passes near the sign post 2. Therefore, the passability of passers-by can be improved.

L'invention concerne une structure de panneau de signalisation (2c), dans laquelle le panneau de signalisation (2c) est un élément de tube creux dont le diamètre externe (D) est un diamètre externe fixe prédéterminé, dont le diamètre interne (d) est un diamètre interne prédéterminé et dont l'épaisseur (t) est une épaisseur prédéterminée. Lorsque le panneau de signalisation (2c) est enterré dans le sol (4), l'épaisseur prédéterminée est constante dans une première zone (5) d'une première position (P1) qui est inférieure à la surface du sol (4a) jusqu'à une seconde position (P2) au-dessus de la surface du sol (4a) d'une distance prédéterminée (L), et des granulés (8) sont disposés dans l'intérieur creux (6) dans la première zone (5) afin de renforcer la résistance à la flexion du panneau de signalisation (2c).
