Description
本発明は、道路の路側や歩車道境界等に設置され、夜間における視認性の向上を図るための反射装置が取付けられた防護柵に関するものである。 The present invention relates to a protective fence that is installed on a roadside or on a pedestrian road boundary or the like and to which a reflecting device for improving visibility at night is attached.
従来、反射装置が取付けられた防護柵については、例えば特許文献１には、以下のような防護柵が開示されている。
すなわち、この防護柵は支柱の頭部上に反射装置である視線誘導標が取付けられたものであって、該視線誘導標は、防護柵の支柱の頭部に嵌め込まれるキャップと、前記キャップの上面上に設けられた板状本体と、前記本体に取付けられた視線誘導用反射体とからなり、そして前記本体は、板幅方向に折れ曲がっており、この折れ曲がり方向と略直交する両側面の上部に反射体が取付けられているものである。
Conventionally, with respect to a protective fence to which a reflection device is attached, for example, Patent Document 1 discloses the following protective fence.
That is, the gaze guide is a reflection device mounted on the head of the support post, and the gaze guide is provided with a cap fitted to the head of the support post and the cap. It consists of a plate-like main body provided on the upper surface, and a line-of-sight guiding reflector attached to the main body, and the main body is bent in the plate width direction, and the upper part of both side surfaces substantially orthogonal to the bending direction. Is provided with a reflector.
しかしながら、上述の如き防護柵に取付けられた視線誘導標においては、防護柵の支柱の頭部に嵌め込まれるキャップの上面上に視線誘導用反射体が取付けられているため、既設の防護柵に取付ける場合、既設のキャップを視線誘導標の取付けられているキャップに取り代える必要があり、施工に時間を要していた。 However, in the line-of-sight guide attached to the protective fence as described above, the line-of-sight guide reflector is mounted on the upper surface of the cap that is fitted to the head of the protective fence post, so that it is attached to the existing protective fence. In this case, it is necessary to replace the existing cap with the cap on which the line-of-sight guide is attached, and it takes time for the construction.
また、視線誘導標が支柱の頭部上に取付けられ、車両の通行位置から離れているため、視認性が問題となり、キャップの嵌め込み位置の角度調整が狂うと、車両からのヘッドライトをうまく再帰反射せず、視認性が低下することもあるため、施工に熟練を要していた。 In addition, the line-of-sight guide is mounted on the head of the column and is away from the vehicle's traffic position, so visibility becomes a problem, and if the angle adjustment of the cap insertion position goes wrong, the headlight from the vehicle is recurred well Since it does not reflect and visibility may fall, construction required skill.
そこで本発明は上記の如き問題点を解消し、反射装置の取付けが容易であり、効率的な視認性が期待できる防護柵を提供せんとするものである。 Accordingly, the present invention is intended to solve the above-described problems, provide a protective fence that can be easily attached to a reflection device and that can be expected to be efficiently visible.
上記目的を達成するために、本発明は次のような構成としている。すなわち、本発明に係る防護柵は、支柱の側面に取付けられた支持金具に横ビームが支持されると共に、支持金具に反射装置が取付けられ、前記支持金具は、相互に隙間を開けて連結される２個の横ビームの端部に両端部がそれぞれ挿入されるインナースリーブと、前記隙間においてインナースリーブを覆うと共に支柱の側面に取付けられる取付金具とからなるものであって、前記インナースリーブを覆う取付金具の先端がアール形状に加工され、前記反射装置は前記取付金具の下面に取付ボルトにより取付けられる取付部と、その取付部の一側縁から下方に折曲され再帰反射体が取付けられた反射部とを備え、且つ前記取付部の先端部に、前記取付金具の先端のアール形状に沿うように、前記アール形状のアールに対応した曲率で湾曲させた係合部が形成され、前記取付ボルトの締結時に、前記取付金具の下面に取付けられる前記取付部の先端部が前記取付金具のアール形状と係合して、取付部の回動を阻止するようにな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 has the following configuration. That is, in the protective fence according to the present invention, the transverse beam is supported by the support fitting attached to the side surface of the support column, and the reflection device is attached to the support fitting, and the support fittings are connected with a gap therebetween. The inner sleeve is inserted into the ends of the two transverse beams, and the inner sleeve is covered with the inner sleeve in the gap, and the mounting bracket is attached to the side surface of the support column, and covers the inner sleeve. The tip of the mounting bracket is processed into a rounded shape, and the reflection device is mounted on the lower surface of the mounting bracket with a mounting bolt, and is bent downward from one side edge of the mounting portion to attach the retroreflector. A reflection portion, and the front end of the mounting portion is curved with a curvature corresponding to the round shape of the round shape so as to follow the round shape of the tip of the mounting bracket. An engaging portion is formed, and when the mounting bolt is fastened, the tip of the mounting portion that is attached to the lower surface of the mounting bracket engages with the round shape of the mounting bracket to prevent rotation of the mounting portion. It is characterized by being made to .
本発明によれば、反射装置の取付けは取付ボルトを締結して行うことから、防護柵への反射装置の取付けが容易であり、且つ反射装置の取付部の回動を阻止する係合部が形成されていることから、細かい角度調整等は不要であり、熟練を要することなく取付けることができる。 According to the present invention, since the reflection device is attached by fastening the attachment bolts, the attachment of the reflection device to the protective fence is easy, and the engagement portion that prevents the reflection device from rotating is provided. Since it is formed, fine angle adjustment or the like is unnecessary, and it can be attached without skill.
本発明において、前記再帰反射体は、互いに平行な上辺と下辺が上下方向に延びる正面視横台形状で形成され、且つ前記上辺と下辺とにおいて、上辺よりも長さの長い下辺が支柱寄りに配置されると共に、支柱に対して下辺よりも外方に配置される上辺が横ビームから突出しない幅で形成されているようにしてもよい。かようにすれば、車両等が接触して破損しないよう横ビームから突出しない幅で再帰反射体を形成する場合、円形状に形成したものに比べ、再帰反射する面積を大きくすることができ、視認性を向上させることができるためである。更には、車両の進行方向を指し示す方向の台形状であるので、優れた視線誘導効果も期待できる。 In the present invention, the retroreflector is formed in a horizontal trapezoidal shape in which the upper side and the lower side parallel to each other extend in the vertical direction, and the lower side that is longer than the upper side is closer to the support column at the upper side and the lower side. The upper side arranged outside the lower side with respect to the support may be formed with a width that does not protrude from the transverse beam . In this way, when the retroreflector is formed with a width that does not protrude from the lateral beam so that the vehicle or the like does not touch and break, the area for retroreflecting can be increased compared to the circular reflector, This is because visibility can be improved. Furthermore, since it has a trapezoidal shape in the direction indicating the traveling direction of the vehicle, an excellent gaze guidance effect can be expected.

FIG. 3 (a) is a top view of a partially cutout of the reflecting device, (b) is a front view, (c) is a right side view, (d) is a left side view, and FIG. 4 is a reflecting device. It is explanatory drawing which looked at from the upper surface.
Ｐは道路等に設置される防護柵であって、１は地面に一定の間隔をおいて立設された支柱、２は支柱１の側面に取付けられた支持金具、３は支持金具２に架設された３段の横ビームであり、支持金具２は相互に隙間を開けて連結される２個の横ビーム３の端部に両端部がそれぞれ挿入されるインナースリーブ２１と、前記隙間においてインナースリーブ２１を覆うと共に支柱１の側面に取付けられ先端がアール形状に加工された取付金具２２とから構成され、取付金具２２に締着された１個の取付ボルト４は、インナースリーブ２１の中央部を貫通しており、横ビーム３とインナースリーブ２１は、インナースリーブ２１を貫通する取付ボルト４の左右に、２個ずつの固定ボルト５により締着されている。これらは、防護柵Ｐに必要な所定の強度を満足するよう、金属材料で形成されている。 P is a protective fence installed on a road or the like, 1 is a support column erected on the ground at a certain interval, 2 is a support bracket attached to the side of the support column 1, and 3 is installed on the support bracket 2. The support bracket 2 has an inner sleeve 21 whose both ends are respectively inserted into end portions of two transverse beams 3 that are connected with a gap therebetween, and an inner sleeve in the gap. 21 and a mounting bracket 22 which is attached to the side surface of the support column 1 and whose tip is processed into a rounded shape. One mounting bolt 4 fastened to the mounting bracket 22 has a central portion of the inner sleeve 21. The transverse beam 3 and the inner sleeve 21 are fastened to the left and right of the mounting bolt 4 that penetrates the inner sleeve 21 by two fixing bolts 5. These are formed of a metal material so as to satisfy a predetermined strength required for the protective fence P.
６は、３段の横ビーム３の最下段の横ビーム３を支持する支持金具２を構成する取付金具２２の下面に取付けられた反射装置であり、該反射装置６は前記取付金具２２に取付ボルト４により取付られる取付部６１と、その取付部６１の一側縁から下方に折曲され再帰反射体６２が取付けられた反射部６３とを備え、前記取付部６１の先端部に取付金具２２と係合して、取付ボルト４の締結時に取付部６１の回動を阻止する係合部６４が形成されている。 Reference numeral 6 denotes a reflecting device attached to the lower surface of the mounting bracket 22 that constitutes the support bracket 2 that supports the lowermost transverse beam 3 of the three-stage transverse beam 3, and the reflecting device 6 is attached to the mounting bracket 22. An attachment portion 61 attached by the bolt 4 and a reflection portion 63 bent downward from one side edge of the attachment portion 61 and attached with a retroreflector 62 are provided. And an engaging portion 64 that prevents the mounting portion 61 from rotating when the mounting bolt 4 is fastened.
そして、この反射装置６を取付金具２２に取付ける際には、取付部６１に形成された取付孔６５に、前記取付ボルト４を挿通させて締着させるのであるが、先端がアール形状に形成された取付金具２２の外形に沿うように、取付部６１の先端部を前記アールに対応した曲率で湾曲させた係合部６４としており、取付ボルト４を締結する際、前記係合部６４が取付金具２２先端のアール形状に沿うことにより、反射装置６は回動することなく簡単に取付金具２２に取付けることができるようになされている。尚、取付孔６５の形状は、丸形状でもよいが、係合部６４を取付金具２２先端のアール形状に沿わせやすいように、係合部６４に向かって長孔形状となされてもよく、また、取付ボルト４を外さないで反射装置６が取付けられるように、取付ボルト４のボルト径よりやや大きな幅でＵ字状に取付部６１を係合部６４に沿って切欠いた切欠となしてもよい。 When the reflection device 6 is mounted on the mounting bracket 22, the mounting bolt 4 is inserted into the mounting hole 65 formed in the mounting portion 61 and tightened, but the tip is formed in a round shape. The fitting portion 64 has a distal end portion curved with a curvature corresponding to the radius so as to follow the outer shape of the fitting fitting 22, and when the fitting bolt 4 is fastened, the engagement portion 64 is attached to the fitting portion 64. By following the round shape at the tip of the metal fitting 22, the reflecting device 6 can be easily attached to the attachment metal fitting 22 without rotating. The mounting hole 65 may have a round shape, but may have a long hole shape toward the engaging portion 64 so that the engaging portion 64 can easily follow the round shape at the tip of the mounting bracket 22. Further, the mounting portion 61 is notched along the engaging portion 64 in a U shape with a width slightly larger than the bolt diameter of the mounting bolt 4 so that the reflection device 6 can be mounted without removing the mounting bolt 4. Also good.
また、反射部６３は、取付部６１に対して５〜１５°の角度で折曲されており、そして取付部６１が支持金具２に取付けられる際には、反射部６３の再帰反射体の向きａが横ビーム３の延設方向ｂに対して５〜１５°の角度θで取付けられるようになされている。これは、車道を走行する車両の方向に再帰反射体６２を向けることによって、車両のヘッドライトの光を効率的に反射させるためである。 In addition, the reflection portion 63 is bent at an angle of 5 to 15 ° with respect to the attachment portion 61, and when the attachment portion 61 is attached to the support bracket 2, the direction of the retroreflector of the reflection portion 63 a is attached at an angle θ of 5 to 15 ° with respect to the extending direction b of the transverse beam 3. This is because the light of the headlight of the vehicle is efficiently reflected by directing the retroreflector 62 toward the vehicle traveling on the roadway.
再帰反射体６２としては、ポリエチレン樹脂、ＡＢＳ樹脂等の熱可塑性合成樹脂の成形体にガラスビーズを半埋込状態に埋設して配設したガラスビーズ埋設反射体が好適に用いられるが、特に限定されたものではなく、レンズ反射体や、多数の反射素子群を形成しその反射素子群の裏面にアルミニウムのような金属の薄膜を金属蒸着法等により積層して反射性能を高めたプリズム状のものや、ガラスビーズやプリズム反射体を表面に配置した反射シート等を適宜用いることができる。 As the retroreflector 62, a glass bead embedded reflector in which a glass bead is embedded in a semi-embedded state in a molded body of a thermoplastic synthetic resin such as a polyethylene resin or an ABS resin is preferably used. It is not a lens-shaped reflector, or a prism-like structure in which a large number of reflective element groups are formed and a thin film of metal such as aluminum is laminated on the back surface of the reflective element groups by a metal vapor deposition method or the like. A reflective sheet having a glass bead or prism reflector disposed on the surface thereof can be used as appropriate.
また、本形態において、再帰反射体６２を正面視台形状に形成しているが、これは、車両等が接触して破損しないよう横ビームから突出しない幅で再帰反射体６２を形成する場合、円形状に形成したものに比べ、再帰反射する面積を大きくすることができ、視認性を向上させることができるためである。更には、車両の進行方向を指し示す方向の台形状とすれば、視線誘導効果も期待できる。 In this embodiment, the retroreflector 62 is formed in a trapezoidal shape when viewed from the front. This is because when the retroreflector 62 is formed with a width that does not protrude from the lateral beam so that the vehicle or the like does not touch and break, This is because the retroreflected area can be increased and the visibility can be improved as compared with a circular shape. Furthermore, if it is trapezoidal in a direction indicating the traveling direction of the vehicle, a line-of-sight guidance effect can also be expected.
