Document Type and Number:
Japanese Patent JP7399126
Kind Code:
B2
Abstract:
To provide a bumper post being lightweight and capable of preventing corrosion.SOLUTION: A bumper post A comprises: a hollow bumper post body 1; a reinforcement member 2A inserted inside the bumper post body; and a holding material 3 for holding the reinforcement member 2A. The reinforcement member 2A is arranged across a buried part 1a buried in a ground and an exposed part 1b exposed to the ground in the bumper post body 1. The holding material 3 holds the lower end part of the reinforcement member 2A. The reinforcement member 2A is a point-symmetrical member in a cross-sectional view, and has a plurality of plate members 21 to 28 radially extending outward from the center. When the lower end of the reinforcement member 2A is higher than the lower end of the bumper post body 1, there is no contact with the concrete as a space is created between the concrete used for the buried part 1a. Therefore, even when the material of the reinforcement member 2A is susceptible to alkali corrosion, it will not corrode.SELECTED DRAWING: Figure 1
