Description
本発明は、車線のセンターライン標示、車線誘導標示或いは交通規制誘導標示、また歩道や公園内への車両進入防止等を目的として、路面に単数または複数で固定・配列された状態で用いる車止め支柱に関するものである。 The present invention is a vehicle stop column used in the state of being fixed or arranged on a road surface in a single or plural form for the purpose of lane center line marking, lane guidance marking or traffic regulation guidance marking, and prevention of vehicle entry into a sidewalk or park, etc. It is about.
従来、車止め支柱に関する発明は種々のものが提案されており、例えば特許文献１には、筒状の円柱体、該円柱体下部のフランジ下面を覆うベース本体の外側に嵌合される押さえリングで道路標識を構成し、上記ベース本体の中央部下面には路面に装着されているボルトまたはナットを螺着するナットまたはボルトが取付けられたものが開示されている。 Conventionally, various inventions related to the vehicle stop column have been proposed. For example, Patent Document 1 discloses a cylindrical columnar body and a pressing ring fitted to the outside of a base body that covers the lower surface of the flange at the bottom of the columnar body. A road sign is disclosed, and a nut or bolt to which a bolt or nut attached to a road surface is screwed is attached to the lower surface of the central portion of the base body.
しかしながら、特許文献１に記載の車止め支柱では、ベース本体の中央部下面に、路面に装着されているボルトまたはナットを螺着するナットまたはボルトが取付けられており、例えばボルトがベース本体の中央部下面に取付けられている場合には、路面に装着されたナット（アンカー）にボルトを螺着して車止め支柱を路面に固定するのであるが、ボルトをナットに螺着して固定するのみであるため、車両に踏み付けられたり、歩行者に蹴られたりすることが度重なると、ボルトがナットから緩んでしまう場合が生じることがある。従って、定期的にボルトを増し締めする作業が必要となり手間が発生していた。また、そのボルトが緩んだ状態において、歩行者が車止め支柱に触れ、緩んでいることを認識すると、車止め支柱を更に緩めてナットから取り外し、盗難されてしまうという問題が発生する懸念もあった。 However, in the vehicle stop column described in Patent Document 1, a nut or bolt to which a bolt attached to a road surface or a nut is screwed is attached to the lower surface of the center portion of the base body. When it is attached to the lower surface, a bolt is screwed to a nut (anchor) mounted on the road surface to fix the vehicle stopper column to the road surface, but only a bolt is screwed to the nut and fixed. Therefore, if the vehicle is stepped on or kicked by a pedestrian, the bolt may loosen from the nut. Therefore, it is necessary to periodically tighten and tighten the bolts, which is troublesome. Further, when the bolt is loosened, if the pedestrian touches the vehicle stop column and recognizes that the bolt is loose, there is a concern that the vehicle stop column is further loosened and removed from the nut and stolen.
本発明は上記の課題を解決するためになされたものであり、繰返し車両等に踏み付けられても、緩み難い車止め支柱を提供せんとするものである。 The present invention has been made in order to solve the above-described problems, and is intended to provide a vehicle stop column that is difficult to loosen even when it is repeatedly stepped on a vehicle or the like.
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、本発明に係る車止め支柱は、円筒状の本体の下端にベース部が取付けられ、該ベース部の下面より突出したボルトがアンカーナットに螺着されることにより、ベース部の下面が設置面に当接されて立設されるようになされた車止め支柱であって、前記ベース部にはその下面より突出した前記ボルトの付け根に段部が形成され、アンカーナットは上面が開口された有底筒状体の内部下方にナット部が形成され、該ナット部の上方に空間部が形成され、設置面に埋設固定された前記アンカーナットの開口縁部とベース部の下面との間に筒状のスペーサーを介して、ベース部のボルトがアンカーナットのナット部に螺着されて、アンカーナットの開口縁部とベース部の下面との間に筒状のスペーサーが挟み付けられていると共に、アンカーナットの開口縁部とベース部の下面との間に筒状の前記スペーサーが挟み付けられている状態で、前記アンカーナットの空間部に挿入されたベース部の段部とナット部との間に、ボルトに挿通されたスプリングワッシャがほぼ平坦になるまで締め付けら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.
That is, the wheel stopper column according to the present invention has a base portion attached to the lower end of a cylindrical main body, and a bolt projecting from the lower surface of the base portion is screwed to the anchor nut so that the lower surface of the base portion is installed on the installation surface. The base is formed with a step at the base of the bolt protruding from the lower surface thereof , and the anchor nut has a bottom with an upper surface opened. A nut portion is formed below the inside of the tubular body, a space portion is formed above the nut portion, and a tubular shape is formed between the opening edge portion of the anchor nut embedded and fixed on the installation surface and the lower surface of the base portion. spacer via the base portion of the bolt is screwed into the nut portion of the anchor nut with cylindrical spacer is sandwiched between the lower surface of the opening edge portion and the base portion of the anchor nut anchor In a state where the cylindrical spacer is sandwiched between the opening edge of the nut and the lower surface of the base portion, the gap between the step portion of the base portion and the nut portion inserted into the space portion of the anchor nut The spring washer inserted through the bolt is tightened until it is substantially flat .
本発明によれば、ベース部にはボルトの付け根に段部を形成し、アンカーナットは上面が開口した有底筒状体の内部下方にナット部を形成し、ナット部の上方に空間部を形成し、設置面に埋設固定したアンカーナットの開口縁部とベース部の下面との間に筒状のスペーサーを介して、ベース部のボルトをアンカーナットのナットに螺着し、且つアンカーナットの空間部に挿入したベース部の段部とナット部との間に、ボルトに挿通したスプリングワッシャをほぼ平坦になるまで締め付けるようにしているので、繰返し車両等に踏み付けられても、スプリングワッシャのスプリング作用によってボルトが緩み難く、ボルトの増し締め作業を低減することができる。また、歩行者等が車止め支柱に触れた際に、緩みが殆ど無く、少々力を入れて廻しても回転しないため、盗難を防止することができる。更に、例えば設置面に穿設した取付孔に液体状の接着剤を流し込み、ベース部の下面より突出したボルトに螺着されたアンカーナットを、前記取付孔に挿入しベース部下面を設置面に当接して車止め支柱を取付けた際に、筒状のスペーサーを介してベース部のボルトをアンカーナットのナット部に螺着しているため、アンカーナットの空間部に接着剤が侵入するのを阻止することができ、よってアンカーナットの空間部に固定されるスプリングワッシャやベース部の段部に接着剤が付着することが無く、円筒状の本体が破損する等して車止めを取替える時に、車止めの交換作業を効率よく実施することができる。 According to the present invention, the base portion is formed with a step at the base of the bolt, the anchor nut is formed with a nut portion below the bottomed cylindrical body having an open top surface, and the space portion is formed above the nut portion. The bolt of the base part is screwed to the nut of the anchor nut via a cylindrical spacer between the opening edge of the anchor nut formed and fixed on the installation surface and the lower surface of the base part, and the anchor nut Since the spring washer inserted through the bolt is tightened between the stepped part of the base part inserted into the space part and the nut part until it becomes almost flat, the spring of the spring washer can be used even if it is repeatedly stepped on the vehicle etc. The bolt is not easily loosened by the action, and the tightening work of the bolt can be reduced. Further, when a pedestrian or the like touches the vehicle stop column, there is almost no looseness, and since it does not rotate even if a little force is applied, theft can be prevented. Further, for example, a liquid adhesive is poured into a mounting hole drilled in the installation surface, and an anchor nut screwed to a bolt protruding from the lower surface of the base portion is inserted into the mounting hole so that the lower surface of the base portion is used as the installation surface. When the car stopper post is installed in contact, the bolt on the base is screwed into the nut of the anchor nut via the cylindrical spacer, preventing the adhesive from entering the space of the anchor nut. Therefore, there is no adhesion of adhesive to the spring washer fixed to the space of the anchor nut and the stepped portion of the base, and when the car stopper is replaced due to damage to the cylindrical main body, etc. Exchange work can be performed efficiently.
本発明に係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。
図１は、本発明に係わる車止め支柱の実施の一形態を示すもので、車止め支柱の形成を示す説明図である。図２は、形成された車止め支柱要部の一部切欠断面を示す断面図である。
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.
FIG. 1 shows an embodiment of a vehicle stop strut according to the present invention, and is an explanatory view showing the formation of a vehicle stop post. FIG. 2 is a cross-sectional view showing a partially cut-away cross section of the main portion of the formed vehicle stopper post.
１は円筒状の本体であって、ポリウレタン系エラストマーにより押出成形され、円筒状で内部が中空部１１となされ、本体１の上端及び下端にそれぞれ、本体１より硬度の高いポリウレタン樹脂を射出成形することで形成した頭部２及びベース部３が取付けられて車止め支柱Ｐが形成される。 Reference numeral 1 denotes a cylindrical main body, which is extrusion-molded by a polyurethane-based elastomer, has a cylindrical shape and has a hollow portion 11, and a polyurethane resin having higher hardness than the main body 1 is injection-molded at the upper end and lower end of the main body 1, respectively. The head 2 and the base 3 formed in this way are attached to form the vehicle stop column P.
頭部２は下方に向かって円筒状の突出部２１が設けられ、突出部２１が中空部１１へ挿入されて、突出部２１の外側面と本体１の内側面とが融着されて頭部２が本体１に取付けられる。また頭部２には、合成樹脂成形体に球形のガラスビーズを埋設した円盤状の反射体Ｒ１が予め嵌着されて取付けられている。 The head 2 is provided with a cylindrical protrusion 21 downward, the protrusion 21 is inserted into the hollow portion 11, and the outer surface of the protrusion 21 and the inner surface of the main body 1 are fused to form a head. 2 is attached to the body 1. In addition, a disc-shaped reflector R1 in which spherical glass beads are embedded in a synthetic resin molded body is fitted and attached to the head 2 in advance.
ベース部３は、上方に向けて円筒状の取付部３１と本体１の下端付近での挫屈度合いを小さくする補強材３２が一体に形成され、またベース部３の下面より突出したボルト４の付け根に段部３３が形成され、更に本体１より硬度の高いポリウレタン樹脂を押出成形することで形成された芯材５が突設されており、頭部２と同様に取付部３１の外側面と本体１の内側面とが融着されて本体１にベース部３が取付けられる。 The base portion 3 is formed integrally with a cylindrical mounting portion 31 and a reinforcing member 32 that reduces the degree of buckling in the vicinity of the lower end of the main body 1, and the bolt 4 protruding from the lower surface of the base portion 3. A step portion 33 is formed at the base, and a core material 5 formed by extruding a polyurethane resin having a hardness higher than that of the main body 1 is protruded from the outer surface of the mounting portion 31 in the same manner as the head portion 2. The base 3 is attached to the main body 1 by fusing the inner surface of the main body 1.
６は上面が開口された有底筒状体の内部下方にナット部６１が形成され、該ナット部６１の上方に空間部６２が形成されたアンカーナットであり、設置面ＧＬに埋設固定されたアンカーナット６の開口縁部６３とベース部３の下面との間に筒状のスペーサー７を介して、ベース部３のボルト４がアンカーナット６のナット部６１に螺着され、且つアンカーナット６の空間部６２に挿入されたベース部３の段部３３とナット部６１との間に、ボルト４に平ワッシャ８とスプリングワッシャ９とを挿通し、該スプリングワッシャ９がほぼ平坦になるまで締め付けられている。かようになすことで、設置面ＧＬにベース部３より下部が埋設されて車止め支柱が固定された際に、スプリングワッシャ９のスプリング作用によって、ベース部３に突設されたボルト４が緩むのを防止することができる。 Reference numeral 6 denotes an anchor nut in which a nut portion 61 is formed inside the bottomed cylindrical body whose upper surface is opened, and a space portion 62 is formed above the nut portion 61. The anchor nut is embedded and fixed in the installation surface GL. The bolt 4 of the base portion 3 is screwed to the nut portion 61 of the anchor nut 6 via the cylindrical spacer 7 between the opening edge portion 63 of the anchor nut 6 and the lower surface of the base portion 3, and the anchor nut 6 A flat washer 8 and a spring washer 9 are inserted into the bolt 4 between the step portion 33 of the base portion 3 and the nut portion 61 inserted into the space portion 62, and tightened until the spring washer 9 becomes substantially flat. It has been. By doing so, when the lower part of the installation surface GL is buried below the base portion 3 and the vehicle stop column is fixed, the bolt 4 protruding from the base portion 3 is loosened by the spring action of the spring washer 9. Can be prevented.
芯材５の外径は本体１の内径より小さくなされており、ベース部３の周囲には合成樹脂に球形のガラスビーズを埋設した帯状の反射体Ｒ２がベース部３に刻設された溝に嵌着されて予め取付けられ、更にベース部３の底面より下方に向けて路面への取付用のボルト４が突設されている。また、本体１の上部には間隔をあけて２ヶ所に本体１の全周に亘って反射シートである反射体Ｒ３が貼着されている。 The outer diameter of the core material 5 is smaller than the inner diameter of the main body 1, and a belt-like reflector R <b> 2 in which spherical glass beads are embedded in a synthetic resin around the base portion 3 is formed in a groove formed in the base portion 3. The bolts 4 are fitted in advance and attached, and further, bolts 4 for attaching to the road surface are projected downward from the bottom surface of the base portion 3. In addition, a reflector R3, which is a reflection sheet, is attached to the upper portion of the main body 1 at two locations over the entire circumference of the main body 1 at intervals.
ここで本体１の硬度は、歩行者や自転車が接触した際に痛みを感じる度合いを小さくしまた負傷する恐れの小さい程度の硬度であり、かかる硬度を発現する合成樹脂は、具体的にはＪＩＳ Ｋ ７２１５（プラスチックのデュロメータ硬さ試験方法）のタイプＡに基づく試験において、約７０〜９０、より好ましくは約７５〜８５となされたものである。また頭部２及びベース部３については、本体１より硬度の高い合成樹脂を用いればよいが、硬度が高すぎると破損の恐れが高まることから、本体１と同じ試験において９５〜１００程度の硬度となされたものが好ましい。 Here, the hardness of the main body 1 is such a hardness that the degree of feeling pain when contacting a pedestrian or a bicycle is small and the risk of injury is small. Specifically, a synthetic resin that expresses such hardness is JIS. In the test based on Type A of K 7215 (Plastic Durometer Hardness Test Method), it is about 70 to 90, more preferably about 75 to 85. For the head 2 and the base 3, a synthetic resin having a hardness higher than that of the main body 1 may be used. However, if the hardness is too high, the risk of breakage increases. Are preferred.
車止め支柱Ｐの、本体１の中空部１１に挿入された芯材５は、その外径が本体１の内径よりも小さくなされていることで、芯材５の周囲と本体１との間には空間Ｋが設けられることとなる。また芯材５は、その下端部５１がベース部３の補強材３２内に挿入され、下端部５１とベース部３の上面とが回転融着されて一体化されている。空間Ｋが設けられていることで、歩行者や自転車が本体１に接触した際に、硬度の低い本体１が空間Ｋ分だけ撓むことができ、芯材５程度の硬度の車止め支柱に接触した場合と較べ、歩行者等が感じる痛みや負傷の恐れを小さいものとできる。また芯材５の高さはは、設置時に自動車のバンパーの高さよりやや高い位置となる５００ｍｍ〜６００ｍｍとし、自動車の衝突時に芯材５に当たる衝撃を自動車の運転者に与えるようにすれば自動車に対する進入防止効果が高められ好ましい。 The core material 5 inserted into the hollow portion 11 of the main body 1 of the vehicle stopper post P has an outer diameter smaller than the inner diameter of the main body 1, so that the space between the periphery of the core material 5 and the main body 1 is between A space K is provided. Further, the lower end portion 51 of the core member 5 is inserted into the reinforcing member 32 of the base portion 3, and the lower end portion 51 and the upper surface of the base portion 3 are rotationally fused and integrated. Since the space K is provided, when a pedestrian or a bicycle contacts the main body 1, the main body 1 having low hardness can be bent by the space K, and contact the car stopper column having a hardness of about the core material 5. Compared with this case, the risk of pain and injury felt by pedestrians and the like can be reduced. Further, the height of the core material 5 is set to 500 mm to 600 mm which is slightly higher than the height of the bumper of the automobile at the time of installation, and an impact on the core material 5 is given to the automobile driver when the automobile collides. This is preferable because the effect of preventing entry is enhanced.
かかる車止め支柱Ｐは、設置面ＧＬに穿設された取付孔Ｈに接着剤Ｓを流し込み、アンカーナット６を接着剤Ｓが充填された取付孔Ｈに装着して、接着剤Ｓが固化するまで養生して、設置面ＧＬへの取付けが終了する。ここで、上記のように、筒状のスペーサー７を介してベース部３のボルト４をアンカーナット６のナット部６１に螺着しているため、アンカーナット６の空間部６２に接着剤Ｓが侵入するのを阻止することができ、よってアンカーナット６の空間部６２に固定されるスプリングワッシャ９やベース部３の段部３３に接着剤が付着することが無いので、車止めの交換作業を効率よく実施することができる。 Such a car stopper column P is poured until the adhesive S is poured into the mounting hole H formed in the installation surface GL, and the anchor nut 6 is mounted in the mounting hole H filled with the adhesive S until the adhesive S is solidified. Curing is completed and the attachment to the installation surface GL is completed. Here, since the bolt 4 of the base portion 3 is screwed to the nut portion 61 of the anchor nut 6 via the cylindrical spacer 7 as described above, the adhesive S is applied to the space portion 62 of the anchor nut 6. It is possible to prevent intrusion, and therefore, no adhesive adheres to the spring washer 9 fixed to the space portion 62 of the anchor nut 6 or the step portion 33 of the base portion 3, so that the vehicle stopper replacement operation is efficient. Can be implemented well.
本体１を形成する材料は、頭部２やベース部３より硬度の低いものであればポリウレタン系エラストマーに限定されるものではないが、車両等の衝突により曲がり且つ復元することで耐久性が高められるよう可撓性に富む材料を用いるのが好ましく、天然ゴムやブタジエンスチレンゴム、ネオプレン、ブタジエンアクリロニトリルゴム、クロロプレン重合体、ブチルゴム等の合成ゴム類、ポリウレタン樹脂、ポリイソブチレン樹脂、エチレン酢酸ビニル共重合体、シリコン樹脂、オレフィン系やウレタン系等エラストマーといった合成樹脂類を好適に用いることができ、これらを発泡させることなく成形し空隙からの千切れを防止するのが好ましい。また上記の硬度約７０〜９０において、車両の衝突や歩行者等の接触に対して十分なたわみを確保するには、本体１の厚みは２ｍｍ〜６ｍｍ程度としておくのが好ましい。 The material forming the main body 1 is not limited to the polyurethane-based elastomer as long as it has a lower hardness than the head 2 and the base 3, but durability is improved by bending and restoring due to a collision of a vehicle or the like. It is preferable to use a material that is highly flexible, such as natural rubber, butadiene styrene rubber, neoprene, butadiene acrylonitrile rubber, chloroprene polymer, butyl rubber, synthetic rubbers, polyurethane resin, polyisobutylene resin, ethylene vinyl acetate copolymer Synthetic resins such as coalescence, silicon resin, olefin-based and urethane-based elastomers can be suitably used, and it is preferable to form them without foaming to prevent tearing from voids. In addition, in the above-described hardness of about 70 to 90, it is preferable that the thickness of the main body 1 is about 2 mm to 6 mm in order to ensure sufficient deflection against a vehicle collision or pedestrian contact.
頭部２、ベース部３及び芯材５を形成する材料は、本体１より硬度の高いものであればポリウレタン樹脂に限定されるものではないが、車両の衝突や衝撃により路面へ叩きつけられたり、車両に踏み付けられる等する恐れがあることから、硬度が高すぎると容易に破損するものとなり耐久性が低下することから、上記の硬度９５〜１００程度のものが好ましく、本体１において挙げた材料で重合度を高める等で硬度を高めたものや、ある程度の弾性を有するポリエチレン樹脂、軟質及び硬質塩化ビニル樹脂等の合成樹脂類を用いることができる。 The material forming the head part 2, the base part 3 and the core material 5 is not limited to polyurethane resin as long as it is harder than the main body 1, but it can be struck against the road surface by a vehicle collision or impact, Since there is a risk of being stepped on the vehicle and the hardness is too high, the material is easily damaged and the durability is lowered. Therefore, the material having the above hardness of about 95 to 100 is preferable. Those having increased hardness by increasing the degree of polymerization or the like, or synthetic resins such as polyethylene resin having a certain degree of elasticity, soft and hard vinyl chloride resin can be used.
また頭部２及びベース部３を本体１に取付けるには、回転融着法が融着部が目立つことなく均一で強固な固着力を得ることができ好適であるが、特に回転融着法に限定されるものではなくその他の熱融着、接着、リベット等を用いた締結を行ってもよい。回転融着を行う場合には、本体１と、頭部２及びベース部３とは相溶性を有する材料としておくことが固着力を高める上で好ましい。また芯材５の下端部５１とベース部３の上面とを固着するには回転融着が固着力を高める上で好ましいが、回転融着に限定されるものではなく、他の熱融着や接着、締結手段等を用いてもよい。 In order to attach the head 2 and the base 3 to the main body 1, the rotational fusion method is preferable because a uniform and strong fixing force can be obtained without making the fusion part conspicuous. There is no limitation, and fastening using other heat fusion, adhesion, rivets, or the like may be performed. In the case of performing rotational fusion, it is preferable that the main body 1, the head 2 and the base 3 are made of compatible materials in order to increase the fixing force. Further, in order to fix the lower end portion 51 of the core material 5 and the upper surface of the base portion 3, rotational fusion is preferable in order to increase the fixing force, but it is not limited to rotational fusion, and other thermal fusion or Adhesion, fastening means, etc. may be used.
かかる車止め支柱Ｐに対し、車両が衝突する際において、本体１は車両のバンパーにより曲折されるが、ここで変形するのは本体１及び芯材５であり、本体１より硬度の高い頭部２及びベース部３は変形することが少なく、本体１及び芯材５は下端でベース部３に固着され、補強材３２により下端付近の挫屈度合いが小さくなされていることで全体に均一に曲がることができ、一定箇所のみが折れ曲がって本体１及び芯材５に曲がり癖が付くのを防ぐようになされている。 When the vehicle collides with the stop column P, the main body 1 is bent by a bumper of the vehicle. However, the main body 1 and the core material 5 are deformed, and the head 2 having higher hardness than the main body 1 is deformed. And the base part 3 is hardly deformed, and the main body 1 and the core material 5 are fixed to the base part 3 at the lower end, and the buckling degree near the lower end is made small by the reinforcing material 32, so that the entire body 1 and the core part 5 are bent uniformly. It is possible to prevent the main body 1 and the core material 5 from bending and wrinkling only at certain points.
車止め支柱Ｐは、車道と歩道との境界付近に設置される場合、予め歩道に埋設されたアンカーナット６に、ベース部３の下面より突設したボルト４が螺着されて歩道上に固着される。かかる車止め支柱Ｐを車道と歩道との境界付近に連続的に設置することで、車両の運転者に対し歩道への進入を心理的に防止すると共に、やむを得ない事情で車両が歩道に乗り上げた際にも、車両を傷つける度合いを金属製のものより格段に小さいものとできる。 When the car stopper post P is installed near the boundary between the roadway and the sidewalk, the bolt 4 protruding from the lower surface of the base portion 3 is screwed to the anchor nut 6 embedded in the sidewalk in advance and is fixed on the sidewalk. The When the vehicle stop strut P is continuously installed in the vicinity of the boundary between the roadway and the sidewalk, the vehicle driver is psychologically prevented from entering the sidewalk, and when the vehicle rides on the sidewalk due to unavoidable circumstances. In addition, the degree of damage to the vehicle can be made much smaller than that made of metal.
本発明に係る車止め支柱は、ベース部にはボルトの付け根に段部を形成し、アンカーナットは上面が開口した有底筒状体の内部下方にナット部を形成し、ナット部の上方に空間部を形成し、設置面に埋設固定したアンカーナットの開口縁部とベース部の下面との間に筒状のスペーサーを介して、ベース部のボルトをアンカーナットのナットに螺着し、且つアンカーナットの空間部に挿入したベース部の段部とナット部との間に、ボルトに挿通したスプリングワッシャをほぼ平坦になるまで締め付けるようにしているので、繰返し車両等に踏み付けられても、スプリングワッシャのスプリング作用によってボルトが緩み難く、ボルトの増し締め作業を低減することができる。また、歩行者等が車止め支柱に触れた際に、緩みが殆ど無く、少々力を入れて廻しても回転しないため、盗難を防止することができる車止め支柱として好適に利用することができる。The vehicle stop strut according to the present invention has a base portion with a stepped portion at the base of the bolt, and the anchor nut has a nut portion formed inside the bottomed tubular body having an open top surface, and a space above the nut portion. The bolt of the base part is screwed onto the nut of the anchor nut through a cylindrical spacer between the opening edge of the anchor nut embedded and fixed to the installation surface and the lower surface of the base part. The spring washer inserted through the bolt is tightened between the stepped part of the base part inserted into the nut space and the nut part until it becomes almost flat. Due to the spring action, the bolt is difficult to loosen, and the bolt tightening operation can be reduced. Further, when a pedestrian or the like touches the vehicle stop column, there is almost no looseness and it does not rotate even if a little force is applied, so that it can be suitably used as a vehicle stop column that can prevent theft.
