Description

本発明は、道路交通の安全と円滑を図るために路面に設けられる区画線又は道路標示（以下、区画線等という。）に用いられる道路鋲の設置方法に関し、特に仮設的に用いられるものに関する。 The present invention is safe and partition lines or road markings provided on the road surface in order to smooth the road traffic relates method of installing studs used (hereinafter, referred to. Demarcation line, etc.), related to those particular are used Temporary .

道路の路面に設けられる区画線等は、路面に専用塗料をペイントしたり、道路鋲を埋め込んだりしてり施工されている。ところが、これらの施工を直ちに行うことができずに、仮設的に区画線等を施工することがある。また、このような仮設的な施工は、道路工事中に本来の車線とは異なる仮の車線を示すときにも行われている。   The lane markings and the like provided on the road surface are constructed by painting a special paint on the road surface or embedding road fences. However, these constructions cannot be performed immediately, and a lane marking or the like may be temporarily constructed. Such temporary construction is also performed when a temporary lane different from the original lane is shown during road construction.

従来、仮設的な区画線等としては、ペンキ、粘着テープ、カラーコーンなどが代用されてきた。しかし、ペンキや粘着テープを用いた場合には、本設の区画線等を施工する前に、路面上のペンキを削り落としたり、粘着テープを路面から剥ぎ取ったりしなければならず、それらの除去作業に多大な労力がかかっていた。また、カラーコーンを用いた場合には、設置撤去作業の煩雑さは少なく繰り返して使用できるが、車両等との接触や風などによって、動いてしまう恐れがあった。しかも、衝撃が加えられて破損した場合には、繰り返しの使用もできなくなっていた。   Conventionally, paints, adhesive tapes, color cones, and the like have been substituted as temporary marking lines. However, when paint or adhesive tape is used, the paint on the road surface must be scraped off or the adhesive tape must be peeled off from the road surface before constructing the main lane markings. The removal work took a lot of effort. In addition, when a color cone is used, the installation and removal work is less complicated and can be used repeatedly. However, there is a risk of moving due to contact with a vehicle or the wind. Moreover, when it was damaged by impact, it could not be used repeatedly.

また、ゴム、合成樹脂等の弾性材からなる基板の少なくとも一上面を底面に対して傾斜面とする道路標示体が考えられている（例えば、特許文献１参照。）。この道路標示体は、弾性材からなり、破損することなく、路面との摩擦で動かないようにしたものである。
特開平６−１１６９１６号公報 Further, a road marking body is considered in which at least one upper surface of a substrate made of an elastic material such as rubber or synthetic resin is inclined with respect to the bottom surface (see, for example, Patent Document 1). This road marking body is made of an elastic material and is not damaged and is not moved by friction with the road surface.
JP-A-6-116916

しかし、特許文献１に記載の道路標示体では、道路標識のような大きなものに用いる場合には適するかもしれないが、区画線等のような小さなものに用いる場合には、車両等との接触、風又は雨水などの路面上の流水によって動いてしまう恐れがある。   However, the road marking body described in Patent Document 1 may be suitable when used for a large object such as a road sign, but when used for a small object such as a lane marking, it may be in contact with a vehicle or the like. There is a risk of moving by running water on the road surface such as wind or rain water.

本発明の課題は、区画線等として用いる道路鋲において、その破損を防止して繰り返し使用できるようにするとともに、動くことを確実に防止し、かつその設置、撤去を容易にすることである。   SUMMARY OF THE INVENTION An object of the present invention is to prevent damage to road fences used as lane markings or the like so that they can be used repeatedly, reliably prevent movement, and facilitate their installation and removal.

以上の課題を解決するため、請求項１に記載の発明は、例えば図１に示すように、道路の路面８に設置される道路鋲（仮設用道路鋲１）であって、道路に打ち込まれる釘部材（コンクリート釘７）によって路面８上に取り付けられる取付部２と、この取付部２から上方に向かって突出して前記取付部２とで中空部６を形成し、柔軟に弾性変形する弾性変形部３とを備え、前記取付部２には前記釘部材に係止される取付穴２ａが前記中空部６に面して形成され、前記弾性変形部３には前記釘部材が通過可能な開口５ａが前記中空部６に面して形成されていることを特徴とする。   In order to solve the above problems, the invention according to claim 1 is a road fence (temporary road fence 1) installed on a road surface 8 of a road, for example, as shown in FIG. An elastic deformation in which a mounting portion 2 mounted on a road surface 8 by a nail member (concrete nail 7) and a protruding portion 2 projecting upward from the mounting portion 2 form a hollow portion 6 to be elastically deformed flexibly. A mounting hole 2a that is engaged with the nail member is formed facing the hollow portion 6, and the elastic deformation portion 3 is an opening through which the nail member can pass. 5 a is formed so as to face the hollow portion 6.

さらに、請求項１に記載の発明は、以上の道路鋲の設置方法であって、前記取付部２を下にして前記道路鋲を路面８上に載置し、前記弾性変形部３を下方に向かって押して弾性変形させ、前記開口５ａを前記取付穴２ａに重なるようにし、前記開口５ａを前記取付穴２ａに重なるようにした状態で、前記釘部材を前記開口５ａから通過させ前記取付穴２ａに挿通させて道路に打ち込み、前記取付穴２ａを前記釘部材に係止させ、前記弾性変形部３をその弾性力によって元の突出した状態に戻して、道路鋲を路面８に設置することを特徴とする。 Furthermore, the invention according to claim 1 is the above-described method for installing the road fence, wherein the road fence is placed on the road surface 8 with the mounting portion 2 facing down, and the elastic deformation portion 3 is directed downward. It is pushed and elastically deformed so that the opening 5a overlaps the mounting hole 2a, and the nail member is passed through the opening 5a with the opening 5a overlapping the mounting hole 2a. And inserting into the road, locking the mounting hole 2a to the nail member, returning the elastically deforming portion 3 to its original protruding state by its elastic force, and installing the road fence on the road surface 8; Features.

このように、道路鋲の取付部２が、道路に打ち込まれる釘部材によって路面８上に取り付けられることにより、車両等との接触や風などによって道路鋲が動かないようにすることができる。また、道路鋲の弾性変形部３が、取付部２から上方に向かって突出して取付部２とで中空部６を形成して柔軟に弾性変形することにより、車両等との接触による衝撃を吸収して、道路鋲が破損しないようにすることができる。通常の使用時には、弾性変形部３はその弾性力により取付部２から突出しており、車両等の運転手からの十分な視認性を確保することができる。   In this way, by attaching the attachment part 2 of the roadside to the road surface 8 by the nail member driven into the road, the roadside can be prevented from moving due to contact with the vehicle or the wind or the like. Further, the elastic deformation portion 3 of the roadway protrudes upward from the attachment portion 2 to form a hollow portion 6 with the attachment portion 2 and flexibly elastically deforms, thereby absorbing an impact caused by contact with a vehicle or the like. Thus, the road fence can be prevented from being damaged. During normal use, the elastic deformation portion 3 protrudes from the mounting portion 2 due to its elastic force, and sufficient visibility from a driver such as a vehicle can be ensured.

そして、中空部６に面して、釘部材に係止される取付穴２ａが取付部２に形成され、釘部材が通過可能な開口５ａが弾性変形部３に形成され、弾性変形部３を下方に向かって押して弾性変形させることにより、弾性変形部３の開口５ａを取付部２の取付穴２ａに重なるようにすることができる。つまり、開口５ａを取付穴２ａに重なるようにした状態で、釘部材を開口５ａから通過させ取付穴２ａに挿通させて道路に打ち込み、取付穴２ａを釘部材に係止させることにより、道路鋲を容易に設置することができる。同様に、開口５ａを取付穴２ａに重ねている状態で、釘部材を引き抜いて道路鋲を容易に撤去することができる。   Then, facing the hollow portion 6, an attachment hole 2 a that is locked to the nail member is formed in the attachment portion 2, and an opening 5 a through which the nail member can pass is formed in the elastic deformation portion 3. By pushing downward and causing elastic deformation, the opening 5 a of the elastic deformation portion 3 can be overlapped with the attachment hole 2 a of the attachment portion 2. That is, with the opening 5a overlapped with the mounting hole 2a, the nail member is passed through the opening 5a, inserted into the mounting hole 2a, driven into the road, and the mounting hole 2a is locked to the nail member. Can be easily installed. Similarly, in a state where the opening 5a is overlaid on the mounting hole 2a, the nail member can be pulled out and the road fence can be easily removed.

さらに、釘部材及び取付穴２ａは弾性変形部３によって保護されるため、車両等が乗り上げてもそれらを破損することはなく、道路鋲を確実に動かないようにすることができる。これにより、道路鋲を破損することなく、繰り返し使用したり、容易に移動させたりすることができる。   Furthermore, since the nail member and the mounting hole 2a are protected by the elastic deformation part 3, even if a vehicle etc. rides, they are not damaged and it can prevent a road fence moving reliably. Thereby, it can be used repeatedly or moved easily without damaging the road fence.

本発明によれば、区画線等として用いる道路鋲において、道路に打ち込まれる釘部材によって路面上に取り付けられる取付部と、この取付部から上方に向かって突出して取付部とで中空部を形成し、柔軟に弾性変形する弾性変形部とを備え、取付部には釘部材に係止される取付穴が中空部に面して形成され、弾性変形部には釘部材が通過可能な開口が中空部に面して形成されているので、弾性変形部を下方に向かって押して弾性変形させ、開口を取付穴に重なるようにし、開口を取付穴に重ねている状態で、釘部材を前記開口から通過させ前記取付穴に挿通させて道路に打ち込み、取付穴を釘部材に係止させて、道路鋲を路面に設置することができ、その破損を防止して繰り返し使用することができ、しかも道路鋲が動くことを確実に防止し、かつその設置、撤去を容易にすることができる。   According to the present invention, in a road fence used as a lane marking or the like, a hollow portion is formed by a mounting portion that is mounted on a road surface by a nail member that is driven into the road, and a mounting portion that protrudes upward from the mounting portion. An elastically deformable portion that is elastically deformed flexibly, and the mounting portion is formed with a mounting hole that engages with the nail member facing the hollow portion, and the elastically deformable portion has a hollow opening through which the nail member can pass Since the elastic deformation portion is pushed downward to be elastically deformed so that the opening overlaps the attachment hole, and the opening is overlapped with the attachment hole, the nail member is removed from the opening. It can be passed through and inserted into the mounting hole, driven into the road, the mounting hole is locked to the nail member, the road fence can be installed on the road surface, and it can be used repeatedly, preventing its breakage, and the road To prevent the kite from moving And it is possible to its installation, to facilitate removal.

以下、図を参照して本発明を実施するための最良の形態を詳細に説明する。本実施の形態の道路鋲は、図１に示すように、道路交通の安全と円滑を図るために道路の路面８に設置されるものであり、本設の区画線又は道路標示（以下、区画線等という。）を施工する前に、仮設的に施工される仮設用道路鋲１である。また、区画線のうち車道中央線、車線境界線、車道外側線に用いるのに適したものとして説明している。   Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the road fence of this embodiment is installed on the road surface 8 of the road for safety and smoothness of road traffic. It is a temporary road fence 1 that is temporarily constructed before constructing a line. Moreover, it demonstrates as a thing suitable for using for a lane center line, a lane boundary line, and a lane outside line among division lines.

また、図１（ｂ）、（ｃ）に示すように、この仮設用道路鋲１が設置される道路は、路盤１０上に表層９を形成したアスファルト舗装となっている。なお、道路の構成はこれに限らず、表層９とともに基層が形成されているものでもよいし、コンクリート舗装などであってもよい。   Further, as shown in FIGS. 1B and 1C, the road on which the temporary road fence 1 is installed is asphalt pavement in which the surface layer 9 is formed on the roadbed 10. In addition, the structure of a road is not restricted to this, The base layer may be formed with the surface layer 9, and concrete pavement etc. may be sufficient.

まず、本実施の形態の仮設用道路鋲１について説明する。図１に示すように、仮設用道路鋲１は、道路に打ち込まれる釘部材によって路面８上に取り付けられる取付部２と、この取付部２から上方に向かって突出して取付部２とで中空部６を形成し、柔軟に弾性変形する弾性変形部３とを備えている。   First, the temporary roadway 1 of the present embodiment will be described. As shown in FIG. 1, the temporary road fence 1 includes a mounting portion 2 that is mounted on the road surface 8 by a nail member that is driven into the road, and a mounting portion 2 that protrudes upward from the mounting portion 2 and has a hollow portion. 6 and an elastically deformable portion 3 that is elastically deformed flexibly.

取付部２は、図１（ａ）に示すように、長方形板状に形成されている。具体的には、例えば長さ７０ｍｍ、幅５０ｍｍ程度のものである。この取付部２には、図１（ｂ）に示すように、釘部材によって係止される取付穴２ａが中空部６に面して形成されている。取付穴２ａは、取付部２の各長辺端部付近に配置され、釘部材の軸部が挿通され頭部で係止される大きさになっている。   As shown in FIG. 1A, the attachment portion 2 is formed in a rectangular plate shape. Specifically, for example, the length is about 70 mm and the width is about 50 mm. As shown in FIG. 1B, the mounting portion 2 is formed with a mounting hole 2 a that is locked by a nail member so as to face the hollow portion 6. The mounting hole 2a is disposed in the vicinity of each long side end portion of the mounting portion 2, and has a size such that the shaft portion of the nail member is inserted and locked at the head portion.

弾性変形部３は、図１（ａ）、（ｂ）に示すように、取付部２の長さ方向に相対する辺から上方に傾斜して延びる一対の長方形板状の傾斜部４と、取付部２の幅方向に相対する辺から上方に垂直に延びる一対の三角形板状の側壁部５とからなっている。具体的には、例えば三角形の頂点の高さが５０ｍｍ程度のものである。また、中空部６は、取付部２、一対の傾斜部４及び一対の側壁部５とで囲まれた空間となっている。   As shown in FIGS. 1A and 1B, the elastically deforming portion 3 includes a pair of rectangular plate-like inclined portions 4 extending obliquely upward from sides facing the length direction of the attaching portion 2, and an attaching portion. It consists of a pair of triangular plate-like side wall portions 5 extending vertically upward from the sides facing the width direction of the portion 2. Specifically, for example, the height of the apex of the triangle is about 50 mm. The hollow portion 6 is a space surrounded by the attachment portion 2, the pair of inclined portions 4, and the pair of side wall portions 5.

ここで、弾性変形部３の材質としては、柔軟に弾性変形するものであればよく、例えば軟質ゴムなどが挙げられる。また、取付部２の材質を弾性変形部３のものと同一として、取付部２と弾性変形部３を一体的に形成してもよい。   Here, the material of the elastic deformation portion 3 may be any material that can be elastically deformed flexibly, and examples thereof include soft rubber. Further, the material of the attachment part 2 may be the same as that of the elastic deformation part 3, and the attachment part 2 and the elastic deformation part 3 may be formed integrally.

各傾斜部４の上面には、矢印４ａ等の表示がなされている。この表示は、粘着テープの貼着、塗料の塗布などにより行うことができる。粘着テープ、塗料には、蓄光（夜光）、蛍光、反射の性質を有するものを用いることができる。また、矢印４ａは、それぞれ傾斜部４において下から上に向かって表示されている。   On the upper surface of each inclined portion 4, an arrow 4a or the like is displayed. This display can be performed by attaching an adhesive tape, applying a paint, or the like. As the adhesive tape and the paint, those having properties of phosphorescence (nightlight), fluorescence, and reflection can be used. Further, the arrows 4a are displayed from the bottom to the top in the inclined portion 4, respectively.

さらに、各側壁部５には、釘部材が通過可能なほぼ半円形の開口５ａが中空部６に面して形成されている。これらの開口５ａは、側壁部５の取付穴２ａ付近の下端部に配置されている。   Further, each side wall portion 5 is formed with a substantially semicircular opening 5 a through which the nail member can pass so as to face the hollow portion 6. These openings 5 a are arranged at the lower end of the side wall 5 near the mounting hole 2 a.

次に、上記仮設用道路鋲１を用いた仮設用道路鋲１の設置方法について説明する。図１（ｃ）に示すように、最初に、取付部２を下にして仮設用道路鋲１を路面８上に載置する。仮設用道路鋲１の向きは、取付部２の長さ方向、すなわち表示された矢印４ａの向きが、道路延長方向（自動車の進行方向）に平行になるようにする。   Next, a method for installing the temporary road fence 1 using the temporary road fence 1 will be described. As shown in FIG. 1 (c), first, the temporary road fence 1 is placed on the road surface 8 with the mounting portion 2 facing down. The direction of the temporary road fence 1 is set so that the length direction of the mounting portion 2, that is, the direction of the displayed arrow 4a is parallel to the road extension direction (the traveling direction of the automobile).

そして、弾性変形部３を下方に向かって押して弾性変形させ、弾性変形部３の側壁部５を内側に倒すようにして、開口５ａを取付穴２ａの上に重なるようにする。このとき、取付穴２ａが外部に対して露出した状態となる。   Then, the elastic deformation portion 3 is pushed downward to be elastically deformed, and the side wall portion 5 of the elastic deformation portion 3 is tilted inward so that the opening 5a overlaps the mounting hole 2a. At this time, the mounting hole 2a is exposed to the outside.

次に、開口５ａを取付穴２ａに重なるようにした状態のまま、コンクリート釘７（釘部材）を開口５ａから通過させ取付穴２ａに挿通させて道路に打ち込み、取付穴２ａをコンクリート釘７に係止させる。具体的には、コンクリート釘７の軸部を取付穴２ａに挿通し、その頭部で取付穴２ａを係止している。   Next, with the opening 5a overlapped with the mounting hole 2a, the concrete nail 7 (nail member) is passed through the opening 5a, inserted into the mounting hole 2a and driven into the road, and the mounting hole 2a is made into the concrete nail 7. Lock. Specifically, the shaft portion of the concrete nail 7 is inserted into the mounting hole 2a, and the mounting hole 2a is locked at the head.

なお、釘部材としては、道路の表層９に打ち込むことができ、取付穴２ａを係止することができれるものであればよく、例えばコンクリート釘７などが挙げられる。   The nail member may be any member that can be driven into the surface layer 9 of the road and can lock the mounting hole 2a, such as a concrete nail 7.

次に、弾性変形部３を押すのをやめて、弾性変形部３をその弾性力によって元の突出した状態に戻す。全ての取付穴２ａにコンクリート釘７を打込むことにより、一つの仮設用道路鋲１の設置が完了する。   Next, pressing of the elastic deformation part 3 is stopped, and the elastic deformation part 3 is returned to the original protruding state by its elastic force. By placing concrete nails 7 in all the mounting holes 2a, the installation of one temporary road fence 1 is completed.

そして、複数の仮設用道路鋲１を一定間隔で路面８に設置して、車道中央線、車線境界線、車道外側線などが形成される。このとき、傾斜部４の矢印４ａの色を黄色と白色とで色を変えて、車道中央線と車道外側線とを分けて示すことができる。また、仮設用道路鋲１を撤去する場合には、同様に開口５ａを取付穴２ａに重なるようにし、コンクリート釘７を引き抜くことで行う。   A plurality of temporary road fences 1 are installed on the road surface 8 at regular intervals to form a roadway center line, a lane boundary line, a roadway outer line, and the like. At this time, the color of the arrow 4a of the inclined portion 4 can be changed between yellow and white, and the road center line and the road outer line can be shown separately. Further, when removing the temporary road fence 1, the opening 5 a is similarly overlapped with the mounting hole 2 a and the concrete nail 7 is pulled out.

以上の実施の形態によれば、仮設用道路鋲１の取付部２を、道路に打ち込まれるコンクリート釘７によって路面８上に取り付けるので、車両等との接触や風などによって仮設用道路鋲１が動かないようにすることができる。また、仮設用道路鋲１の弾性変形部３が、取付部２から上方に向かって突出して取付部２とで中空部６を形成して柔軟に弾性変形することにより、車両等との接触による衝撃を吸収して、仮設用道路鋲１が破損しないようにすることができる。通常の使用時には、弾性変形部３はその弾性力により取付部２から突出しており、傾斜部４が車両等の運転手に相対しているので、十分な視認性を確保することができる。   According to the above embodiment, the attachment part 2 of the temporary road fence 1 is attached on the road surface 8 by the concrete nails 7 driven into the road, so that the temporary road fence 1 is brought into contact with a vehicle or the like by wind or the like. It can be prevented from moving. Further, the elastic deformation portion 3 of the temporary road fence 1 protrudes upward from the attachment portion 2 and forms a hollow portion 6 with the attachment portion 2 so as to be elastically deformed flexibly, thereby being brought into contact with a vehicle or the like. It is possible to absorb the impact and prevent the temporary road fence 1 from being damaged. During normal use, the elastic deformation portion 3 protrudes from the attachment portion 2 due to its elastic force, and since the inclined portion 4 faces the driver of a vehicle or the like, sufficient visibility can be ensured.

そして、中空部６に面して、コンクリート釘７に係止される取付穴２ａが取付部２に形成され、コンクリート釘７が通過可能な開口５ａが弾性変形部３の側壁部５に形成され、弾性変形部３を下方に向かって押して側壁部５を内側に倒すようにして弾性変形させることにより、弾性変形部３の側壁部５の開口５ａを取付部２の取付穴２ａに重なるようにすることができる。つまり、開口５ａを取付穴２ａに重なるようにした状態で、コンクリート釘７を開口５ａから通過させ取付穴２ａに挿通させて道路に打ち込み、取付穴２ａをコンクリート釘７に係止させることにより、仮設用道路鋲１を容易に設置することができる。同様に、開口５ａを取付穴２ａに重なるようにしている状態で、コンクリート釘７を引き抜いて仮設用道路鋲１を容易に撤去することができる。   Then, facing the hollow portion 6, a mounting hole 2 a locked to the concrete nail 7 is formed in the mounting portion 2, and an opening 5 a through which the concrete nail 7 can pass is formed in the side wall portion 5 of the elastic deformation portion 3. Then, the elastic deformation portion 3 is pushed downward to be elastically deformed by tilting the side wall portion 5 inward, so that the opening 5a of the side wall portion 5 of the elastic deformation portion 3 overlaps the mounting hole 2a of the mounting portion 2. can do. That is, with the opening 5a overlapping the mounting hole 2a, the concrete nail 7 is passed through the opening 5a, inserted into the mounting hole 2a and driven into the road, and the mounting hole 2a is locked to the concrete nail 7, The temporary road fence 1 can be easily installed. Similarly, with the opening 5a overlapped with the mounting hole 2a, the concrete nail 7 can be pulled out and the temporary road fence 1 can be easily removed.

さらに、コンクリート釘７及び取付穴２ａは弾性変形部３によって保護されるため、車両等が乗り上げてもそれらを破損することはなく、仮設用道路鋲１を確実に動かないようにすることができる。これにより、仮設用道路鋲１を破損することなく、繰り返し使用したり、容易に移動させたりすることができる。   Furthermore, since the concrete nail 7 and the mounting hole 2a are protected by the elastic deformation part 3, even if a vehicle etc. rides, they will not be damaged and it can prevent moving the temporary road fence 1 reliably. . Thereby, it can be repeatedly used or moved easily without damaging the temporary road fence 1.

なお、以上の実施の形態においては、道路鋲を仮設用としたが、本発明はこれに限定されるものではなく、本設用としても良い。また、車道中央線、車線境界線、車道外側線に用いることとしたが、その他の区画線、追越禁止、横断歩道などの道路標示に用いてもよい。また、道路鋲の外形は、例えば、取付部を円形板状とし弾性変形部を半球状としてもよいし、取付部を長方形板状とし弾性変形部を台座状としてもよい。また、開口を側壁部に形成しているが、傾斜部に形成してもよく、弾性変形部が半球状、台座状であればその頂部に形成してもよい。その他、傾斜部、取付穴、開口、表示などの形状、数なども任意であり、具体的な細部構造等についても適宜に変更可能であることは勿論である。   In the above embodiment, the road fence is used for temporary installation, but the present invention is not limited to this and may be used for permanent installation. In addition, although it is used for the roadway center line, the lane boundary line, and the roadway outside line, it may be used for road markings such as other lane markings, overtaking prohibitions, and pedestrian crossings. In addition, the outer shape of the road fence may be, for example, a circular plate shape of the attachment portion and a hemispherical shape of the elastic deformation portion, or a rectangular plate shape of the attachment portion and a base shape of the elastic deformation portion. Moreover, although the opening is formed in the side wall portion, it may be formed in the inclined portion, or may be formed in the top portion if the elastic deformation portion is hemispherical or pedestal. In addition, the shape, number, and the like of the inclined portion, the mounting hole, the opening, and the display are arbitrary, and it is needless to say that the specific detailed structure can be changed as appropriate.
