BUMPER POST
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
【課題】軽量であり腐食を防止できる車止めを提供する【解決手段】中空の車止め本体１と、車止め本体の内部に挿入される補強部材２Ａと、補強部材２Ａを保持するための保持材３とを備える車止めＡであって、補強部材２Ａは、車止め本体１における地中に埋設される埋設部１ａと地上に露出する露出部１ｂとにわたって配置され、保持材３は補強部材２Ａの下端部を支持している。補強部材２Ａは、横断面視において点対称の部材であって、中心から外側に向かって放射状に延びる複数の板材２１～２８を有している。補強部材２Ａの下端部が車止め本体１の下端部より上位にあると埋設部１ａに用いられるコンクリートとの間に空間ができるので、コンクリートと接触することがない。このため、補強部材２Ａの材料がアルカリ腐食しやすいものであっても、腐食することはない。【選択図】図１
