図１４の形態は、注意喚起板３の基板４と取付部５とが一体化して形成されているものであって、基板４の上端と下端には、正面側の一部が切り欠かれた、横ビーム２の外形に対応した内形の一部切欠円形体からなる取付部５が形成され、又基板４は背面側に開口する箱型となされ、左右側壁４３の一部が中段ビーム２ｂの外形に沿って切り欠かれている。そして上方の取付部５を上段ビーム２ａに嵌め合わせ、又下方の取付部５を下段ビーム２ｃに嵌め合わせ、さらに左右側壁４３の切欠部を中段ビーム２ｂに嵌め合わせることにより、注意喚起板３が横ビーム２に取付けられるようになされている。又、上段ビーム２ａと中段ビーム２ｂ、中段ビーム２ｂと下段ビーム２ｃの各々の間の空間部に底壁が裏面側に突出するようにして基板４の表面に形成された凹部７に再帰性反射体８が収容されている。 In the form of FIG. 14, the substrate 4 and the mounting portion 5 of the attention calling plate 3 are integrally formed, and a part of the front side is notched at the upper end and the lower end of the substrate 4. The mounting portion 5 is formed of a partially cut circular body having an inner shape corresponding to the outer shape of the transverse beam 2, and the substrate 4 is formed in a box shape that opens to the back side, and a part of the left and right side walls 43 is formed in the middle beam 2b. It is cut out along the outer shape. Then, the upper mounting portion 5 is fitted to the upper beam 2a, the lower mounting portion 5 is fitted to the lower beam 2c, and the notch portions of the left and right side walls 43 are fitted to the middle beam 2b. It can be attached to the transverse beam 2. Further, retroreflection is applied to the concave portion 7 formed on the surface of the substrate 4 so that the bottom wall protrudes to the back side in the space between the upper stage beam 2a and the middle stage beam 2b, and the middle stage beam 2b and the lower stage beam 2c. A body 8 is accommodated.
本発明に係る防護柵は、注意喚起板が取付けられているため、従来の防護柵自体の機能に加えて注意喚起が行えると共に、製作が容易であり、任意の位置に表示を施すことができ、且つ既設の防護柵にも適用することができるので、特にＴ字状に道路が交差した箇所に設置されて、ドライバーに対して道路の進行方向等を表し注意喚起を行う防護柵として、好適に利用することができる。 Since the guard fence according to the present invention is provided with a warning board, it can be alerted in addition to the function of the conventional guard fence itself, and can be easily manufactured, and can be displayed at any position. It can also be applied to existing protective fences, so it is particularly suitable as a protective fence that is installed at a location where the road intersects in a T-shape and expresses the direction of the road and alerts the driver. Can be used.
