Description

【０００１】
【発明の属する技術分野】
この発明は、丸パイプ柱支持金具、特に、丸パイプ柱を壁面に取り付けるに際し、横ずれや落下を確実に防止することができる丸パイプ柱支持金具に関するものである。
【０００２】
【従来の技術】
従来、道路用安全柵やフェンス等は、地面に構築される以外に、路肩や構造物に構築される場合がある。この場合には、道路用安全柵やフェンス等の支柱は、路肩や構造物の壁に固定することになる。このような場合には、図１６に示すように、支柱４１は、支柱４１に合わせて円弧状に湾曲させた、それぞれ同一形状の上部金具４２と下部金具４３とによって、例えば、構造物の垂直な壁４４に埋め込まれたアンカーボルトにナット４５により固定していた。
【０００３】
また、上部金具４２および下部金具４３の内面に突起（図示せず）を形成したり、図１７に示すように、下部金具４３に底板４６を固定して、支柱４１の落下防止を図っていた。
【０００４】
【発明が解決しようとする課題】
しかしながら、支柱４１の落下防止を図るために、底板４６が固定された下部金具４３を使用すれば、過大な荷重がかかっても確実に支柱４１の落下を防止することができるが、構造が異なる２種類の金具を用意することになり、その分、金具の製造コストの高騰や在庫管理の煩雑さが避けられない。
【０００５】
一方、内面に突起を形成して支柱４１との摩擦抵抗を増加させる上部金具４２および下部金具４３を使用する場合には、ある程度の支柱４１の落下防止効果は得られるが、過大な荷重には耐えられない。
【０００６】
また、ナット４５の締め付け具合によっては、上部金具４２および下部金具４３と支柱４１との間に隙間が生じて支柱４１が横ずれする恐れがある。
【０００７】
従って、この発明の目的は、丸パイプ柱を壁面に取り付けるに際し、横ずれや落下を確実に防止することができる丸パイプ柱支持金具を提供することにある。

In order to fix the column to the vertical corner wall with the above-described round pipe column support fitting for the corner, as shown in FIG. 15, the anchor bolt 13 is embedded in the vertical corner wall 12, and the upper bracket 26 and the anchor bolt 13 are embedded. The lower metal fitting 30 may be temporarily fixed with the nut 14, and then the column (P) may be inserted into the upper metal fitting 26 and the lower metal fitting 30 from above and the nut 14 may be tightened. Since the column (P) is pressed against the corner of the wall 12 by the two metal fittings 26 and 30, it does not shift laterally, and is placed on the drop preventing protrusion 33 of the lower metal fitting 30, so that even if an excessive load is applied. There is no fear of falling.

【The invention's effect】
As described above, according to the present invention, when attaching a round pipe column to a vertical plane wall, a vertical protruding corner wall, or a vertical entering corner wall, it is possible to reliably prevent a lateral displacement or a drop due to an excessive load. The effect is brought about.
