Description

本発明は、道路柵、防護柵などの柵や手摺等のビームの取付構造に関し、特に支柱に所要の角度で連結する柵や手摺等のビームの取付構造に関する。   The present invention relates to a beam attachment structure such as a fence such as a road fence and a protection fence and a handrail, and more particularly to a beam attachment structure such as a fence and a handrail connected to a column at a required angle.

従来、道路柵、防護柵などの柵において、この柵に用いられるビームを支柱に支持する方法として種々の方法が考えられている。例えば、ビームを支柱に溶接する方法、あるいは実公昭５８−２４９７２公報に記載されているように、支柱に形成した貫通孔の両側からビームの端部を扁平状に形成した連結部を挿入し、その連結部どうしをボルト・ナットで連結して支柱に固定するという方法が提案されている。
しかし、上記のようにビームを支柱に溶接する方法は、現場にて溶接することが必要であるために溶接装置の搬送やセッティングなどが面倒であり、その操作に熟練を要すると共にコスト高ともなっていた。また、ビームの端部を扁平状に形成した連結部どうしを連結する方法は、その連結部が扁平状であるために強度上弱くなり、また扁平状の部分がパイプ状のビームと太さや外形が相違し、全体の見映えの点でも問題があった。 Conventionally, in a fence such as a road fence and a protective fence, various methods have been considered as a method of supporting a beam used for the fence on a support column. For example, a method of welding the beam to the column, or, as described in Japanese Utility Model Publication No. 58-24972, insert a connecting portion in which the end of the beam is formed flat from both sides of the through hole formed in the column, There has been proposed a method in which the connecting portions are connected to each other by bolts and nuts and fixed to a column.
However, the method of welding the beam to the column as described above requires welding on site, so that the conveyance and setting of the welding apparatus are troublesome, and the operation requires skill and high cost. It was. In addition, the method of connecting the connecting portions in which the end portions of the beam are formed in a flat shape is weak in strength because the connecting portions are flat, and the flat portion has a thickness and outer shape similar to that of a pipe-shaped beam. However, there was a problem in terms of overall appearance.

更に、実公平４−３９２８５公報に開示されているように、柵を水平面内、垂直面内及びこれらの両方の面内において自在に斜めに位置することができるようにビームを支柱に支持する方法も提案されている。この方法は、支柱の周囲に係合するリング状の支柱挟持部とビームに連結するビーム挟持部を有する一対のブラケットを設け、このブラケットをボルト・ナットで固定し、ボルト・ナットを調整することによってビームを自由な方向に向けるようにしたものである。
しかし、この方法も、リング状の支柱挟持部が強度上弱く、またブラケットとビームの太さや形状等が相違し、外観上においても問題があった。 Further, as disclosed in Japanese Utility Model Publication No. 4-39285, a method of supporting a beam on a support so that a fence can be freely positioned in a horizontal plane, a vertical plane, and both planes. Has also been proposed. This method includes providing a pair of brackets having a ring-shaped column holding part that engages with the periphery of the column and a beam holding unit connected to the beam, fixing the bracket with a bolt and nut, and adjusting the bolt and nut. Is intended to direct the beam in any direction.
However, this method also has a problem in appearance because the ring-shaped column holding portion is weak in strength and the thickness and shape of the bracket and the beam are different.
