Description

本発明は、道路、歩道橋、公園、駅前広場、遊歩道あるいはその他の道路等の道路柵として、好適に使用される防護柵に関するものである。   The present invention relates to a protective fence that is suitably used as a road fence for roads, pedestrian bridges, parks, station squares, promenades, or other roads.

路側に間隔をあけて立設した各支柱の上端部の車道側の面に又は支柱上端に取り付けたキャップの車道側の面に、それぞれブラケットを介して円筒状のインナースリーブをビームパイプ長手方向の向きで取り付け、各インナースリーブに円筒状のビームパイプの端部をそれぞれ外嵌させ、この外嵌部を貫通するボルト及びこれに螺合させたナットにより、各ビームパイプをインナースリーブに固定してなる防護柵において、キャップの上端部分が傾斜した平面となされ、該平面がブラケットの上面と連続して設けられている構成が開示されている（例えば特許文献１）。   Cylindrical inner sleeves in the longitudinal direction of the beam pipe are respectively attached to the road-side surface of the upper end of each column that is erected on the road side or on the road-side surface of the cap attached to the upper end of the column via a bracket. The end of the cylindrical beam pipe is externally fitted to each inner sleeve, and each beam pipe is fixed to the inner sleeve by a bolt penetrating this external fitting part and a nut screwed to this. In such a protective fence, a configuration is disclosed in which the upper end portion of the cap is an inclined plane, and the plane is provided continuously with the upper surface of the bracket (for example, Patent Document 1).

特開２００６−１０４７５６号公報JP 2006-104756 A

しかしながら、特許文献１に記載のような防護柵では、キャップの上端全体が平面となされているので、第一の継手金具として支柱と同程度の幅の継手金具を用いる必要があり、通常のガードパイプに用いられる継手金具を用いた場合にはキャップ上平面の両側部付近と継手上平面とが連続せず、継手金具とキャップとの一体感が得られにくくなるものであった。またキャップ上平面が単なる平坦面となされていることで、とりわけキャップが合成樹脂等の比較的機械的強度が小さい材料から形成されている場合には、キャップ上平面に衝撃が加わると凹む等の変形をする恐れのあるものであった。   However, in the protective fence as described in Patent Document 1, since the entire upper end of the cap is flat, it is necessary to use a joint fitting having the same width as that of the support as the first joint fitting. When a joint fitting used for a pipe is used, the vicinity of both sides of the upper plane of the cap and the upper plane of the joint are not continuous, making it difficult to obtain a sense of unity between the joint fitting and the cap. In addition, since the upper surface of the cap is a simple flat surface, particularly when the cap is formed of a material having a relatively low mechanical strength such as a synthetic resin, the cap surface is recessed when an impact is applied. There was a risk of deformation.

本発明は上記の如き課題に鑑みてなされたものであり、継手金具の幅が支柱の幅より大幅に小さい場合でも、支柱上端付近において継手金具からキャップまでの一体感を得ることができ、またキャップに衝撃が加えられた場合でもキャップの上面が変形する恐れを小さくすることができる防護柵を提供せんとするものである。   The present invention has been made in view of the problems as described above, and even when the width of the fitting is significantly smaller than the width of the column, it is possible to obtain a sense of unity from the fitting to the cap near the upper end of the column. An object of the present invention is to provide a protective fence that can reduce the risk of deformation of the upper surface of the cap even when an impact is applied to the cap.

上記目的を達成するため、本発明は以下のような構成としている。すなわち、本発明に係わる防護柵は、適宜間隔をおいて立設した支柱の車道側に継手金具を用いてビームが取り付けられ、前記支柱の上端にキャップが取り付けられ、前記ビームを支柱に取り付ける最上段の継手金具である第一の継手金具と前記キャップとが近接して設けられている防護柵であって、前記キャップの上面に設けられた平面状のキャップ上平面と、前記第一の継手金具の上面で平面状となされた継手上平面とが略連続して設けられ、前記継手金具の幅が支柱の幅の三分の二以下となされると共に、前記継手金具の幅と前記上端平面の幅とが略同一となされ、前記キャップの上面に更にキャップ上平面の周縁から前記継手上平面に続く部分を除いて、支柱の外側縁に向かって下がる平面状の傾斜面が形成されていることを特徴とするものである。   In order to achieve the above object, the present invention is configured as follows. In other words, the guard fence according to the present invention has a beam attached to the roadway side of the support column that is erected at an appropriate interval using a fitting, a cap is attached to the upper end of the support column, and the beam is attached to the support column. A protective fence in which a first joint fitting which is an upper joint fitting and the cap are provided close to each other, the planar upper surface of the cap provided on the upper surface of the cap, and the first joint And a joint upper plane formed in a flat shape on the upper surface of the metal fitting, and the width of the joint metal fitting is less than two-thirds of the width of the column, and the width of the joint metal fitting and the upper end plane. A flat inclined surface is formed on the upper surface of the cap, except for a portion continuing from the peripheral edge of the upper surface of the cap to the upper surface of the joint, toward the outer edge of the column. With features Is shall.

本発明に係わる防護柵によれば、キャップ上平面と継手上平面とが略連続され且つ幅が略同一となされていることで、継手金具の幅が支柱の幅より大幅に小さい場合でも、支柱上端付近において継手金具からキャップまでの一体感を得ることができる。またキャップの上面において、キャップ上平面から支柱の外側縁に向かって下る傾斜面が形成されていることで、キャップ上平面と傾斜面との間にリブが形成され、キャップに衝撃が加わった場合でもキャップの上面が変形する恐れを小さくすることができる。   According to the protective fence according to the present invention, the upper surface of the cap and the upper surface of the joint are substantially continuous and have substantially the same width, so that even when the width of the joint metal fitting is significantly smaller than the width of the pillar, A sense of unity from the fitting to the cap can be obtained in the vicinity of the upper end. In addition, a rib is formed between the upper surface of the cap and the inclined surface by forming an inclined surface that descends from the upper surface of the cap toward the outer edge of the column, and an impact is applied to the cap. However, the risk of the upper surface of the cap being deformed can be reduced.

However, the risk of the upper surface of the cap being deformed can be reduced.

本発明に係わる最良の実施の形態について、図面に基づき以下に具体的に説明する。   BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.

図１は、本発明に係わる防護柵の、実施の一形態を示すもので、（ａ）は防護柵全体を車道側から見た状態を示す正面図、（ｂ）は防護柵の支柱付近の詳細を示す斜視図である。まず（ａ）において、防護柵１０は、標準的には２ｍ又は３ｍといった適宜の間隔をおいて立設した支柱３の車道側に、最上段の継手金具２及びその他の継手金具２Ａを用いて上下方向に三段のビーム４が取り付けられ、継手金具２と継手金具２Ａとは同一のものであり、継手金具２の幅Ｗ１は支柱３の幅Ｗ２の約半分程度となされている。支柱３は、継手金具２が取り付けられている支柱３Ａと、下方からビーム４を支持する受け金具５のみが取り付けられた支柱３Ｂとが交互に配置されている。   1A and 1B show an embodiment of a protective fence according to the present invention, in which FIG. 1A is a front view showing the entire protective fence as viewed from the roadway side, and FIG. It is a perspective view showing details. First, in (a), the protective fence 10 uses the uppermost fitting fitting 2 and other fitting fittings 2A on the side of the roadway of the column 3 that is erected with an appropriate interval of 2 m or 3 m as a standard. Three-stage beams 4 are attached in the vertical direction, and the fitting 2 and the fitting 2A are the same, and the width W1 of the fitting 2 is about half of the width W2 of the support column 3. As for the support | pillar 3, the support | pillar 3A to which the coupling metal fitting 2 is attached, and the support | pillar 3B to which only the receiving metal fitting 5 which supports the beam 4 from the downward direction are arrange | positioned alternately.

次に（ｂ）において、支柱３の上端に取り付けられたキャップ１は、合成樹脂を用いて一体に成形されたものであり、最上段のビーム４を支柱３に取り付けている第一の継手金具２は、支柱３の上端に取り付けられたキャップ１に近接して設けられている。キャップ１の上面には、馬蹄状の形状となされた平面状であるキャップ上平面１１が形成され、第一の継手金具２はビーム４に挿通されたインナースリーブ６を把持する形状のブラケット状となされ、第一の継手金具２の上面には同じく平面状となされた継手上平面２１が設けられている。継手金具２及び２Ａは、支柱３に挿通された取付ボルトＢ１により支柱３にボルト止めされて取り付けられ、取付ボルトＢ１は更にキャップ１の支柱３内に挿入された部分（図示せず）にも挿通されることで、支柱３からキャップ１が抜けるのを防止している。また継手金具２及び２Ａにはインナースリーブ６が挿通されて取付ボルトＢ２によりボルト止めされ、インナースリーブ６はビーム４内に挿通されると共に取付ボルトＢ３によりボルト止めがなされている。   Next, in (b), the cap 1 attached to the upper end of the support column 3 is integrally formed using a synthetic resin, and the first joint fitting for attaching the uppermost beam 4 to the support column 3 is shown. 2 is provided close to the cap 1 attached to the upper end of the column 3. On the upper surface of the cap 1, a flat upper surface 11 having a horseshoe shape is formed, and the first joint fitting 2 has a bracket shape that holds the inner sleeve 6 inserted into the beam 4. The upper surface of the first joint fitting 2 is provided with a joint upper surface 21 that is also flat. The joint fittings 2 and 2A are bolted and attached to the support column 3 by mounting bolts B1 inserted through the support column 3, and the installation bolt B1 is also attached to a portion (not shown) inserted into the support column 3 of the cap 1. By being inserted, the cap 1 is prevented from coming off from the column 3. An inner sleeve 6 is inserted into the joint fittings 2 and 2A and is bolted by a mounting bolt B2. The inner sleeve 6 is inserted into the beam 4 and is bolted by a mounting bolt B3.

このキャップ上平面１１の馬蹄状を形成する幅Ｗ３と第一の継手金具２の幅Ｗ２とは略同一となされると共に、キャップ上平面１１と継手上平面２１との高さも略同一となされることで、キャップ上平面１１と継手上平面２１とは略連続して設けられて、キャップ１と第一の継手金具２との間に一体感が生じるようになされている。キャップ１の上面には、更にキャップ上平面１１を形成する馬蹄状の、継手上平面２１に続く部分を除いて、キャップ上平面１１を囲んで支柱３の外側縁３１に向かって下がる平面状の傾斜面１２が形成されている。傾斜面１２はキャップ上平面１１に対して約１５゜の傾斜となされることで、それ程違和感が生じることなくキャップ上平面１１と傾斜面１２との間が屈曲されてリブ１３となされる。このリブ１３により、キャップ１の上面が単なる平坦面となされている場合と比較してはるかに衝撃等により変形が生じる恐れが小さくなされている。   The width W3 forming the horseshoe shape of the upper cap surface 11 and the width W2 of the first joint fitting 2 are substantially the same, and the heights of the cap upper surface 11 and the joint upper surface 21 are also substantially the same. Thus, the cap upper plane 11 and the joint upper plane 21 are provided substantially continuously so that a sense of unity is produced between the cap 1 and the first joint fitting 2. On the upper surface of the cap 1, except for a horseshoe-shaped surface that forms the cap upper plane 11, the flat surface that surrounds the cap upper plane 11 and descends toward the outer edge 31 of the column 3 except for the portion following the joint upper plane 21. An inclined surface 12 is formed. The inclined surface 12 is inclined by about 15 ° with respect to the cap upper surface 11, so that the rib 13 is bent between the cap upper surface 11 and the inclined surface 12 without much discomfort. The rib 13 reduces the possibility of deformation due to impact or the like as compared with the case where the upper surface of the cap 1 is a simple flat surface.
