Description

本発明は、車道境界などに設置される防護柵に関し、特に上端開口にキャップが取り付けられた支柱を備えた防護柵に関する。   The present invention relates to a protective fence installed at a roadway boundary or the like, and more particularly, to a protective fence including a column having a cap attached to an upper end opening.

一般に、防護柵、ガードフェンス等に用いられる支柱は、管状の鋼材が多く用いられ、支柱上端の開口を塞ぐために、様々なキャップが提案されている。そして、キャップの支柱への取り付け方法としては、ボルト、ネジ、リベット等で接合する方法がある。しかしながら、このようなボルト等で接合する方法では、現場施工に時間がかかってしまう。また、接合した後にボルト等が支柱表面に突設されるため、車両や歩行者が引っ掛かる可能性があり、非常に危険である。   In general, a tubular steel material is often used for a support column used in a protective fence, a guard fence, and the like, and various caps have been proposed to close the opening at the upper end of the support column. As a method of attaching the cap to the support column, there is a method of joining with a bolt, a screw, a rivet or the like. However, in such a method of joining with bolts or the like, it takes time for on-site construction. In addition, since the bolts and the like are projected from the surface of the support after joining, there is a possibility that a vehicle or a pedestrian may be caught, which is very dangerous.

このような問題に対して、ボルト等で接合しない取り付け方法が種々提案されている。例えば特許文献１のキャップでは、支柱とキャップのどちらか一方に取り付けられた弾性体が他方に係止されて、防護柵支柱の上端にキャップが取り付けられている。   In order to solve such a problem, various attachment methods that do not use bolts or the like have been proposed. For example, in the cap of Patent Document 1, an elastic body attached to one of the support column and the cap is locked to the other, and the cap is attached to the upper end of the protective fence support column.

A tubular beam member, which is installed between the plurality of support columns and whose longitudinal end is in contact with the support columns, and a through-hole that penetrates the tube wall of the main body unit, is provided inside the tube of the beam material. And a bolt for attaching the beam material to the support column, and the cap has a head that covers an opening at an upper end of the main body, and a hanging piece that is suspended from the head and inserted into the opening. The hanging piece is formed with a hole into which a bolt inserted into the through hole is inserted.

また、前記キャップは、前記本体部の周方向に回転可能であり、前記垂下片に形成された孔は、前記本体部の周方向に長手方向を持つ長孔であり、前記長孔は、前記本体部の周方向に２つ並んで形成されてもよい。 Further, the cap is rotatable in the circumferential direction of the main body, the hole formed in the hanging piece is a long hole having a longitudinal direction in the circumferential direction of the main body, and the long hole is Two may be formed side by side in the circumferential direction of the main body.

The beam members 30 may be sequentially arranged. In this case, as shown in FIG. 4, the fixing of the two beam members 30 to the main body 11 is performed using separate bolts 20a and 20b, and T bolts or the like can be used as the bolts 20a and 20b.

図４の構成においては、一のビーム材３０の連結片３１の壁の貫通孔及び本体部１１の貫通孔にボルト２０ａを挿通し、挿通したボルト２０ａにナット２１ａを螺結することで、一のビーム材３０が本体部１１に固定される。そして、他のビーム材３０の連結片３１の壁の貫通孔及び本体部１１の貫通孔にボルト２０ｂを挿通し、挿通したボルト２０ｂにナット２１ｂを螺結することで、他のビーム材３０が本体部１１に固定される。キャップ１２の垂下片１４の２つの長孔はそれぞれ周方向に長手方向を持つため、図３のような２つのビーム材３０の長手方向が平行な構成のみならず、図４のような２つのビーム材３０の長手方向が交差する構成においても、ボルト２０ａ及び２０ｂを垂下片１４の長孔に挿通させ、ボルト２０ａ及び２０ｂによりキャップ１２を本体部１１に固定することができる。   In the configuration of FIG. 4, the bolt 20 a is inserted into the through hole in the wall of the connecting piece 31 of the beam member 30 and the through hole of the main body 11, and the nut 21 a is screwed into the inserted bolt 20 a. The beam member 30 is fixed to the main body 11. Then, the bolt 20b is inserted into the through hole in the wall of the connecting piece 31 of the other beam member 30 and the through hole of the main body 11, and the nut 21b is screwed into the inserted bolt 20b, whereby the other beam member 30 is It is fixed to the main body 11. Since the two long holes of the hanging piece 14 of the cap 12 each have a longitudinal direction in the circumferential direction, not only the configuration in which the longitudinal directions of the two beam members 30 are parallel as shown in FIG. Even in the configuration in which the longitudinal directions of the beam members 30 intersect, the bolts 20a and 20b can be inserted into the elongated holes of the hanging piece 14, and the cap 12 can be fixed to the main body 11 by the bolts 20a and 20b.

この構成により、道路の曲がり具合に応じて、所定の角度をもってビーム材３０を配置する場合、本体部１１の２つの貫通口の位置を調整するだけで、対応することができる。すなわち、道路の曲がり具合に応じて、キャップ１２の仕様を変更する必要がないため、製造コストが安価で、かつ、納期面で有利な防護柵１を実現することができる。 With this configuration, when the beam member 30 is arranged at a predetermined angle according to the degree of bending of the road, it can be dealt with only by adjusting the positions of the two through holes of the main body 11. That is, since it is not necessary to change the specifications of the cap 12 according to the curve of the road, it is possible to realize the protective fence 1 that is inexpensive in manufacturing and advantageous in terms of delivery time.

本発明は、防護柵の支柱に取り付けられるキャップ等において広く利用することができる。   The present invention can be widely used in a cap or the like attached to a support fence post.
