特開２００６−９７４３０号公報JP 2006-97430 A

特許文献１に示されるように、従来より用いられているアンカーナットはアルミニウム合金などの金属で製造されているため、設置後に道路工事などを行う場合には施工機などを傷つけないように事前に撤去しなければならないという問題があった。   As shown in Patent Document 1, since the anchor nuts that have been used in the past are manufactured from a metal such as an aluminum alloy, when performing road construction after installation, the construction machine or the like is not damaged in advance. There was a problem that it had to be removed.

そこで本発明は、道路工事などに際して上記のような埋設部材の撤去作業が不要な道路用標示体の設置方法を提案するものである。   Therefore, the present invention proposes a method for installing a road marking body that does not require the above-described removal work of the buried member during road construction or the like.

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る道路用標示体の設置方法は、柱形状に形成された本体部と該本体部の下端を支持固定するベース部とを備えた道路用標示体の設置方法であって、
前記ベース部の下端面の中央には円柱形状の凸部が下方に突出して設けられ、
該凸部の中央にはアンカーボルトが雄ねじ部を下方に突出して設けられており、
路面には前記アンカーボルトの雄ねじ部と螺結可能な雌ねじ部が形成された繊維強化樹脂製のアンカーナットが前記雌ねじ部を上方向に向けて埋設固定され、
前記雌ねじ部の上端には前記凸部の形状に対応した円柱形状の凹部が設けられており、
前記凹部に前記凸部を収納させて前記雌ねじ部に前記アンカーボルトを螺結させ、前記アンカーナットの上端部を前記ベース部の下端面に当接させてベース部を路面に固定させたことを特徴としている。 In order to achieve the above object, the present invention is configured as follows.
That is, the road sign object installation method according to the present invention is a road sign object installation method comprising a main body part formed in a columnar shape and a base part that supports and fixes the lower end of the main body part,
At the center of the lower end surface of the base portion, a cylindrical convex portion is provided protruding downward,
An anchor bolt is provided at the center of the convex portion so that the male screw portion projects downward,
On the road surface, an anchor nut made of fiber reinforced resin in which a female thread part that can be screwed with a male thread part of the anchor bolt is embedded and fixed with the female thread part facing upward,
A cylindrical concave portion corresponding to the shape of the convex portion is provided at the upper end of the female screw portion,
The convex portion is stored in the concave portion, the anchor bolt is screwed to the female screw portion, and the upper end portion of the anchor nut is brought into contact with the lower end surface of the base portion to fix the base portion to the road surface. It is a feature.

本発明に係る道路用標示体の設置方法によれば、アンカーナットを繊維強化樹脂で形成するので、埋設固定したアンカーナットの上から工事を行っても施工機を傷つけることがない。
またベース部の下端面に設けた凸部をアンカーナットの凹部に収納し、アンカーボルトをアンカーナットに螺結させて固定するので、路面に固定したベース部に車両などが衝突して横向きの力が加えられたときに、凸部の側壁が凹部の内周壁に当接され、アンカーナットの雌ねじ部に集中しやすい応力が分散されるため、雌ねじ部が破壊されにくくなる。またアンカーナットの上端がベース部の下端面に当接しているので、ベース部に車両などが衝突したときに与えられる下方向の衝撃や荷重などは、アンカーナットの雌ねじ部だけに掛かるのではなくベース部の下端面に当接したアンカーナットの上端部に分散されるため、アンカーナットの雌ねじ部が破壊されにくくなる。 According to the method for installing the road marking body according to the present invention, the anchor nut is formed of fiber reinforced resin, so that the construction machine is not damaged even if construction is performed from above the anchor nut that is buried and fixed.
Also, the convex part provided on the lower end surface of the base part is housed in the concave part of the anchor nut, and the anchor bolt is screwed to the anchor nut and fixed. Is applied, the side wall of the convex part is brought into contact with the inner peripheral wall of the concave part, and stress that tends to concentrate on the female thread part of the anchor nut is dispersed, so that the female thread part is not easily broken. Also, since the upper end of the anchor nut is in contact with the lower end surface of the base part, the downward impact or load applied when a vehicle or the like collides with the base part is not applied only to the female thread part of the anchor nut. Since it is distributed to the upper end portion of the anchor nut in contact with the lower end surface of the base portion, the female thread portion of the anchor nut is less likely to be destroyed.

また、前記のアンカーナットを、ガラス繊維を含有させた、ポリアミド樹脂及び／又はポリブチレンテレフタレート樹脂及び／又はポリエチレンテレフタレート樹脂及び／又はポリアセタール樹脂及び／又はポリファニレンサルファイド樹脂のいずれかを選択または組み合わせた樹脂を主成分として形成すれば、高い強度と耐衝撃性能を備えることができるので、設置した道路用標示体に車両などが衝突してもアンカーナットの雌ねじ部が破壊されにくくなる。   Further, the anchor nut may be selected or combined with any one of a polyamide resin and / or a polybutylene terephthalate resin and / or a polyethylene terephthalate resin and / or a polyacetal resin and / or a polyfanylene sulfide resin containing glass fiber. If the resin is formed as a main component, high strength and impact resistance can be provided, so that even if a vehicle or the like collides with the installed road marking body, the female thread portion of the anchor nut is not easily broken.

本発明に係る道路用標示体の設置方法によれば、埋設固定したアンカーナットを事前に撤去することなく道路工事などを行うことができる。   According to the method for installing a road marking body according to the present invention, road construction and the like can be performed without removing the anchor nut embedded and fixed in advance.

本発明の実施の形態を図面に基づき具体的に説明する。

The main body portion 1 is formed of a cylindrical hollow columnar body, and a reflection sheet 11 having retroreflectivity that reflects outgoing light in parallel to incident light is attached to the upper outer surface thereof. The material of the main body 1 is preferably a thermoplastic polyurethane, a soft polyolefin, an elastomer, or the like in consideration of ease of molding, resilience to treading of a vehicle, durability, and the like.

２は、反射部材である。反射部材２は、帯状の形状をした基材２２に適宜間隔をおいてガラスビーズ製の反射器２１が配設されている。反射器２１は入射光に対して平行に光を反射する再帰反射性が高く、かつ汚れにくく、劣化しにくいガラスビーズ製のものを用いるのが好ましいが、基材２２の表面に反射テープなどを貼着してもよい。基材２２の材質は、鉄鋼、ステンレス、アルミニウムなどの金属などを用いてもよいが、反射器２１を埋め込み形成することを容易にするためにゴム、ウレタン系樹脂、エラストマーなどの弾性の高い合成樹脂を用いるのが好ましく、反射器２１が外れにくくなるように、ポリエチレンやポリプロピレン等、ある程度高い硬度を有する熱可塑性合成樹脂を用いるのがより好ましい。   2 is a reflecting member. The reflecting member 2 is provided with a reflector 21 made of glass beads with an appropriate interval on a strip-shaped base material 22. The reflector 21 is preferably made of glass beads having high retroreflectivity that reflects light parallel to the incident light, and is not easily contaminated or deteriorated. However, a reflective tape or the like is used on the surface of the base material 22. You may stick. The material of the base material 22 may be a metal such as steel, stainless steel, or aluminum. However, in order to make it easy to embed and form the reflector 21, a highly elastic synthetic material such as rubber, urethane resin, or elastomer is used. It is preferable to use a resin, and it is more preferable to use a thermoplastic synthetic resin having a certain degree of hardness, such as polyethylene or polypropylene, so that the reflector 21 is difficult to come off.

３は、ベース部である。ベース部３は円柱形状をしており、その上面には本体部１を挿入する環状溝３１が形成されている。本体部１はその下端を環状溝３１に挿入され融着されて固定されている。
ベース部３の側壁には、帯状の反射部材２を取り付けるための側壁溝部３５が全周に亘って形成されている。ベース３の材質は、成形の容易さおよび車両等の踏みつけに対する復元性、耐久性等を考慮すると、熱可塑性ポリウレタンや軟質ポリオレフィン、エラストマーなどが好適である。また、耐衝撃性に優れる塩化ビニル、ＡＳＡ樹脂、ＡＢＳ樹脂なども好適に用いることができる。
帯状の反射部材２は、ベース部３の側壁溝部３５に巻回されて取り付けられている。反射部材２は、側壁溝部３５に巻回させることで外れにくくなると共に、反射器２１をベース部３の外面からそれ程突設させることなく設けることができ、また上下方向への位置ずれを防ぐことができ好ましい。また、ベース部３の外周への反射部材２の取り付けは、側壁溝部３５を設けずに行っても良い。また、反射部材２は、反射テープをそのまま貼着してもよく、ガラス製の反射器をそのままベース部３の外周に埋め込むように取り付けてもよい。
また、本実施形態ではベース部３は円柱形状に形成しているが、これに限るものではなく円錐台形状など他の形状に形成してもよい。 3 is a base part. The base portion 3 has a cylindrical shape, and an annular groove 31 into which the main body portion 1 is inserted is formed on the upper surface thereof. The lower end of the main body 1 is inserted into the annular groove 31 and fused and fixed.
On the side wall of the base portion 3, a side wall groove portion 35 for attaching the band-like reflecting member 2 is formed over the entire circumference. The material of the base 3 is preferably a thermoplastic polyurethane, a soft polyolefin, an elastomer, or the like in view of ease of molding, resilience to treading of a vehicle, durability, and the like. Moreover, vinyl chloride, ASA resin, ABS resin, etc. which are excellent in impact resistance can also be used suitably.
The belt-like reflecting member 2 is wound around and attached to the side wall groove portion 35 of the base portion 3. The reflecting member 2 is not easily detached by being wound around the side wall groove portion 35, and the reflector 21 can be provided without projecting so much from the outer surface of the base portion 3, and also prevents displacement in the vertical direction. This is preferable. Further, the reflection member 2 may be attached to the outer periphery of the base portion 3 without providing the side wall groove portion 35. Further, the reflecting member 2 may be attached with a reflecting tape as it is, or may be attached so that a glass reflector is embedded in the outer periphery of the base portion 3 as it is.
Moreover, in this embodiment, although the base part 3 is formed in the column shape, you may form not only in this but in other shapes, such as a truncated cone shape.

ベース部３の下端面３２の中央には円柱形状の凸部３３が下方に突出して設けられている。またその中央にはアンカーボルト５が雄ねじ部５１を下方に向けて固定されている。   At the center of the lower end surface 32 of the base portion 3, a cylindrical convex portion 33 is provided so as to protrude downward. In addition, an anchor bolt 5 is fixed at the center with the male screw portion 51 facing downward.

アンカーナット４は、片方の端部が開口した有底筒状の形状に形成されており、その外周部分には路面に埋設固定したときに容易に抜けて外れないように切欠き部４４が形成されている。
アンカーナット４は、ベース３を設置する路面６に穿設された埋設穴に挿入された状態で、その周囲の埋設穴との隙間にモルタル材やセメントなどの固定材７が充填されて、固定される。 The anchor nut 4 is formed in a bottomed cylindrical shape with one end opened, and a cutout portion 44 is formed on the outer peripheral portion thereof so that the anchor nut 4 is not easily detached when it is embedded and fixed on the road surface. Has been.
The anchor nut 4 is inserted into a buried hole drilled in the road surface 6 where the base 3 is installed, and a fixing material 7 such as mortar or cement is filled in a gap between the anchor nut 4 and the surrounding buried hole. Is done.

アンカーナット４の内周部分には、アンカーボルト５の雄ねじ部５１と螺結可能な雌ねじ部４２が形成されている。また、アンカーナット４の開口端付近の内周部分には、前記凸部３３に対応した円柱形状の凹部４１が凸部３３を収納可能に形成されている。
アンカーナット４は、繊維強化樹脂を材料として射出成形により形成されている。繊維強化樹脂の種類としては、成形性の容易さ、耐衝撃性能の良好さなどから、ガラス繊維を含有した、ポリアミド樹脂、ポリブチレンテレフタレート樹脂、ポリエチレンテレフタレート樹脂、ポリアセタール樹脂、ポリファニレンサルファイド樹脂のいずれかを選択または組み合わせた樹脂などを好適に用いることができる。これらの繊維強化樹脂を用いてアンカーナット４を形成することで、路面にアンカーナット４を埋設した状態で路面の切断、研磨、穿孔などを伴う工事を行っても、アンカーナット４自体が砕けるので施工機を傷つけたり損なう恐れがない。また同様の目的で、繊維強化樹脂以外の、セラミックなどの陶器を材料としてアンカーナット４を形成することも可能である。 On the inner peripheral portion of the anchor nut 4, a female screw portion 42 that can be screwed with the male screw portion 51 of the anchor bolt 5 is formed. A cylindrical recess 41 corresponding to the projection 33 is formed in the inner peripheral portion near the opening end of the anchor nut 4 so as to accommodate the projection 33.
The anchor nut 4 is formed by injection molding using a fiber reinforced resin as a material. The types of fiber reinforced resins include polyamide resins, polybutylene terephthalate resins, polyethylene terephthalate resins, polyacetal resins, and polyphenylene sulfide resins that contain glass fibers because of their ease of moldability and good impact resistance. Resins or the like in which any one is selected or combined can be suitably used. By forming the anchor nut 4 using these fiber reinforced resins, the anchor nut 4 itself is crushed even if the road surface is cut, polished, drilled, or the like with the anchor nut 4 embedded in the road surface. There is no risk of damaging or damaging the construction machine. For the same purpose, it is also possible to form the anchor nut 4 using ceramics or other ceramics other than the fiber reinforced resin.

アンカーナット４は凹部４１を上方向に向けて路面に埋設固定される。
このアンカーナット４の雌ねじ部４２に雄ねじ５１を螺入して締結させると、凸部３３が凹部４１に収納されて、ベース部３が路面に固定される。
このような状態でベース部３が固定されるので、車両などが衝突してベース部３に横向きの力が加えられたときには、凸部３３の側壁が凹部４１の内周壁に当接されるため、雌ねじ部４２と雄ねじ部５１との螺結部分の根本に集中しやすい応力が分散されアンカーナット４の雌ねじ部４２が破壊されにくくなる。 The anchor nut 4 is embedded and fixed on the road surface with the concave portion 41 facing upward.
When the male screw 51 is screwed into the female screw portion 42 of the anchor nut 4 and fastened, the convex portion 33 is accommodated in the concave portion 41 and the base portion 3 is fixed to the road surface.
Since the base portion 3 is fixed in such a state, the side wall of the convex portion 33 comes into contact with the inner peripheral wall of the concave portion 41 when a vehicle or the like collides and a lateral force is applied to the base portion 3. The stress that tends to concentrate on the root of the threaded portion between the female screw portion 42 and the male screw portion 51 is dispersed, and the female screw portion 42 of the anchor nut 4 is not easily broken.

また雌ねじ部４２に雄ねじ５１を螺結させたときには、アンカーナット４は、その上端部４３をベース部３の下端面３２に当接してベース部３を固定する。このため、車両などが衝突してベース部３に下向きの力が加えられたときには、アンカーナット４の雌ねじ部４２に全ての力が加わらず、ベース部３の下端面３２に当接したアンカーナット４の上端部４３で分散されるため、アンカーナット４の雌ねじ部４２が破壊されにくくなる。   When the male screw 51 is screwed into the female screw portion 42, the anchor nut 4 abuts the upper end portion 43 against the lower end surface 32 of the base portion 3 and fixes the base portion 3. Therefore, when a downward force is applied to the base portion 3 due to a vehicle collision or the like, all the force is not applied to the female screw portion 42 of the anchor nut 4 and the anchor nut that is in contact with the lower end surface 32 of the base portion 3. 4, the internal thread portion 42 of the anchor nut 4 is hardly broken.
