Description
本発明は、ポールタイプの車止めに関する。さらに詳しくは、自動車の進入禁止区域の表示と自動車の強制停止機能をもたせたポールタイプの車止めに関する。 The present invention relates to a pole-type car stopper. More specifically, the present invention relates to a pole type car stop provided with an indication of a car entry prohibited area and a forced stop function of the car.
ポールタイプの車止めの従来技術として、特許文献1,2および非特許文献1記載の技術がある。
特許文献1の従来技術は、アルミニウム製の円筒状パイプからなる支柱本体と、この支柱本体の上端部に取付けたフック部からなる。支柱本体はアルミニウム製のパイプであることから強度の高いものではない。フック部はチェーンを取付けるための部品であるが、フックだけパイプの外に出て見え、ナットはパイプの内に収容されているので、美麗な外観が得られるというものである。
As a conventional technique of a pole-type car stop, there are techniques described in Patent Documents 1 and 2 and Non-Patent Document 1.
The prior art of Patent Document 1 includes a column main body made of an aluminum cylindrical pipe and a hook portion attached to the upper end of the column main body. The support main body is not strong because it is an aluminum pipe. The hook part is a part for attaching the chain, but only the hook can be seen out of the pipe, and the nut is accommodated in the pipe, so that a beautiful appearance can be obtained.
しかるに、上記特許文献1の従来技術は、パイプ内が空洞であるため、例えば、自動車が衝突する等の強い衝撃が加わった場合、比較的折れ曲りやすいものである。また、フック部にはチェーンは取付けられても手すり等の棒材を取付けることはできない。 However, the prior art disclosed in Patent Document 1 is relatively easy to bend when a strong impact such as a collision of an automobile is applied, for example, because the inside of the pipe is hollow. In addition, even if the chain is attached to the hook portion, a bar such as a handrail cannot be attached.
特許文献2の従来技術は、アルミニウム製の筒体の内部に鋼製のパイプを挿入した車止めと、内部に鋼製の棒体を挿入した車止めである。
しかるに、この特許文献2の従来技術は、(ア)筒体の下端部が地中に埋設されていない場合、筒体と地表面との隙間が生じやすくなり外観が良くないとか、(イ)筒体の下端部を地中に埋設(固定)した場合、化粧材でもある筒体が破損した際に、ハツリ作業等が必要となって交換に手間がかかるという問題がある。
The prior art of Patent Document 2 is a car stopper in which a steel pipe is inserted into an aluminum cylinder and a car stopper in which a steel rod is inserted inside.
However, according to the prior art of this patent document 2, (a) if the lower end of the cylinder is not buried in the ground, a gap between the cylinder and the ground surface is likely to occur, and the appearance is not good (a) In the case where the lower end portion of the cylindrical body is buried (fixed) in the ground, when the cylindrical body which is also a cosmetic material is broken, there is a problem that the operation such as a hatching is required, and the replacement takes time.
非特許文献1の従来技術は、鋼管製のパイプの内部にコンクリートを充填した車止めである。
しかるに、この非特許文献1の従来技術は、鋼管製パイプのみを用いているので、外観上の美感はなく、人目に触れる場所での商品価値は低い。また、外観に傷が付いた場合は、車止め全体を取り除いて交換するしかなく、その場合、パイプ下端部はコンクリート基礎に埋設されているので、ハツリ作業が必要になって多大な工数を要することになる。
The prior art of Non-Patent Document 1 is a car stopper in which concrete is filled in a pipe made of steel pipe.
However, since the prior art of this non-patent document 1 uses only a steel pipe pipe, there is no aesthetic appearance and the commercial value in a place where it is noticeable is low. In addition, when the appearance is damaged, it is only necessary to remove the entire car stop and replace it, in which case the lower end of the pipe is buried in a concrete foundation, requiring a flocking operation and requiring a large number of man-hours become.
本発明は上記事情に鑑み、高い強度を有し、損傷部の交換が容易に行えるポールタイプの車止めを提供することを目的とする。 SUMMARY OF THE INVENTION In view of the above-described circumstances, the present invention has an object to provide a pole type vehicle stopper having high strength and capable of easily replacing a damaged part.

According to the first aspect of the invention, the strength can be enhanced by using a double structure car stop consisting of the inner pillar and the outer pillar extrapolated thereto. Further, by dividing the outer pillar into upper and lower outer pillars, it is possible to replace only the easily damaged upper outer pillar. Therefore, it is possible to easily replace the damaged part without the need for a fry or the like at the time of replacement, and to suppress the cost at the time of replacement. Furthermore, by fixing the lower part of the lower outer column in the ground, a gap can not be made between the ground surface and the outer column, and the appearance is improved because the inner column can not be seen.

In addition, when the plate-like holding portion is positioned between the inner surface of the outer pillar and the outer surface of the inner pillar, rattling of the outer pillar can be suppressed.
つぎに、本発明の実施形態を図面に基づき説明する。
(基本構造)
図1および図2に示すように、本実施形態の車止めAは、金属製の内柱1と化粧用の外柱2とで二重構造に構成される筒体である。内柱1も外柱2も中空の部材であり、その断面形状は円形に限られず、矩形その他の多角形であってもよい。図示の実施形態では、内柱1も外柱2も断面円形の筒体を用いた二重筒体となっている。
Next, an embodiment of the present invention will be described based on the drawings.
(Basic structure)
As shown in FIG. 1 and FIG. 2, a car stop A of the present embodiment is a cylindrical body configured in a double structure by a metal inner column 1 and a cosmetic outer column 2. Both the inner pillar 1 and the outer pillar 2 are hollow members, and the cross-sectional shape thereof is not limited to a circle, but may be a rectangle or other polygons. In the illustrated embodiment, both the inner column 1 and the outer column 2 are double cylinders using cylinders having a circular cross section.
内柱1は、車止めの強度を保持するための部材(芯材)であり、鉄や鋼等が好適である。この内柱1の外表面は、錆等を防止する目的で、メッキやポリエステル粉体焼付塗装などが施されてもよい。内柱1の全長は約700〜1400mmであり、埋設部分の長さが約200〜400mmで、地表面からの長さが約500〜1000mmである。 The inner pillar 1 is a member (core material) for maintaining the strength of the vehicle stop, and iron or steel is suitable. The outer surface of the inner pillar 1 may be plated or baked with polyester powder for the purpose of preventing rust and the like. The total length of the inner pillar 1 is about 700 to 1400 mm, the length of the embedded portion is about 200 to 400 mm, and the length from the ground surface is about 500 to 1000 mm.
外柱2は車止めAを美麗にするための部材であり、アルミニウムの押出し形材が好適である。このアルミニウム製の外柱2の表面には、陽極酸化塗装複合皮膜やアクリル溶剤焼付塗装やポリエステル粉体焼付塗装など任意の仕上げが施される。外柱2の長さは、内柱1の地表面からの長さより若干長い長さであればよく、概ね530〜1060mmである。 The outer pillar 2 is a member for making the car stopper A beautiful, and an extruded shape of aluminum is suitable. The surface of the aluminum outer pillar 2 is subjected to an arbitrary finish such as an anodized coating composite film, an acrylic solvent baking coating, or a polyester powder baking coating. The length of the outer pillar 2 should just be a little longer than the length from the ground surface of the inner pillar 1, and is about 530-1060 mm in general.
図1に示すように、外柱2および内柱1の上部にはキャップ9が取り付けられビス等で固定されている。このキャップ9は内柱1や外柱2内へ雨水が入るのを防止し、車止めAの外観を美しくするための部材である。また、キャップ9に反射材や光源を設けることで、夜間でも車止めAの視認性を高めることができる。 As shown in FIG. 1, a cap 9 is attached to the upper part of the outer pillar 2 and the inner pillar 1 and fixed with screws or the like. The cap 9 is a member for preventing rainwater from entering the inner pillar 1 and the outer pillar 2 and making the appearance of the car stopper A beautiful. Further, by providing the cap 9 with a reflective material or a light source, the visibility of the car stop A can be enhanced even at night.
内柱1には、後述するように、施工時に充填材が充填される(図1には充填材は示されていない)。充填材としては、内柱1の強度が高められるものであれば、とくに制約なく種々の材料を利用できる。たとえば、セメント系材料や、土砂、金属粉、樹脂などを例示できる。 As will be described later, the inner pillar 1 is filled with a filler during construction (the filler is not shown in FIG. 1). As the filler, various materials can be used without any limitation as long as the strength of the inner pillar 1 can be increased. For example, cement-based materials, earth and sand, metal powder, resin and the like can be exemplified.
充填材は、充填後に硬化するものが好ましい。内柱1には後述するボルトキャップ7を配置することで、充填材が硬化するとボルトキャップ7の周囲が硬化した充填材で囲まれて、内柱1内に空間が形成できる。そのため、内柱1内に後述する固定用ボルト8を挿入でき、ボルト固定が行えるようになる。 The filler is preferably one that hardens after filling. By disposing a bolt cap 7 to be described later on the inner pillar 1, when the filler is cured, the periphery of the bolt cap 7 is surrounded by the cured filler, and a space can be formed in the inner pillar 1. Therefore, a fixing bolt 8 to be described later can be inserted into the inner pillar 1 so that the bolt can be fixed.
充填後に硬化する充填材としては、セメント系材料が好ましい。本明細書でいうセメント系材料には、コンクリートやモルタル等種々の材料が含まれる。充填材として圧縮強度の高いセメント系材料を充填すると、外部から衝撃が加えられても、内柱1の屈曲が生じにくくなる。換言すれば、内柱1の外径を大きくせずに強度を向上できる。このようにして、車止めAの直径等の寸法を大きくしなくても対屈曲強度が高くなり、自動車の衝突等の外部からの衝撃によっても、容易には倒壊しない車止めが得られる。
また、施工性およびコストの観点から、充填材としては、車止めAの基礎孔内に充填される材料(コンクリート)と同じ材料であることがより好ましい。
As a filler which hardens after filling, a cement-based material is preferable. The cement-based material referred to in the present specification includes various materials such as concrete and mortar. When a cement-based material having a high compressive strength is filled as the filler, even if an impact is applied from the outside, the inner pillar 1 is hardly bent. In other words, the strength can be improved without increasing the outer diameter of the inner column 1. Thus, even if the dimensions such as the diameter of the vehicle stop A are not increased, the bending strength becomes high, and the vehicle stop which can not be easily collapsed by external impact such as a collision of a car can be obtained.
Moreover, as a filler, it is more preferable that it is the same material as the material (concrete) with which it is filled in the base hole of car stop A from a viewpoint of construction property and cost.
(外柱の交換構造)
図1および図2において、GLは地表面を示している。図1に示すように、外柱2は上外柱3と下外柱4の二つの部材からなり、設置状態で地表面上5〜60mm、好ましくは30〜60mmとなる位置で上外柱3と下外柱4に上下分割されている。上外柱3は内柱1の地表面から上方の露出部分をほぼ覆うが、内柱1の地表面から上方の長さよりも少し短い長さの部材であり、通常は450〜950mmの長さをもっている。下外柱4は地中に埋められる部分と地上に露出する部分をもつ長さの部材であり、通常は80〜110mmの長さをもっている。
(Exterior pillar replacement structure)
In FIG. 1 and FIG. 2, GL indicates the ground surface. As shown in FIG. 1, the outer column 2 consists of two members, an upper outer column 3 and a lower outer column 4, and in the installed state the upper outer column 3 at a position of 5 to 60 mm, preferably 30 to 60 mm. And the lower outer column 4 are divided up and down. The upper outer column 3 substantially covers the exposed upper part of the inner column 1 from the ground surface, but is a member slightly shorter than the upper line from the ground surface of the inner column 1, and usually has a length of 450 to 950 mm. Have The lower outer pillar 4 is a member having a length having a portion buried in the ground and a portion exposed to the ground, and usually has a length of 80 to 110 mm.
下外柱4は内柱1に対しネジ5で固定されており、上外柱3も内柱1に対してネジ5で固定されている。なお、手すり21を取付けるときは固定用ボルト8が内柱1にねじ込まれるが、この固定用ボルト8の詳細については、後述する。 The lower outer column 4 is fixed to the inner column 1 with screws 5, and the upper outer column 3 is also fixed to the inner column 1 with screws 5. Note that the fixing bolt 8 is screwed into the inner pillar 1 when the handrail 21 is attached. Details of the fixing bolt 8 will be described later.
前記上外柱3と下外柱4との間には、位置決め部材10が介装されている。
この位置決め部材10は、合成樹脂製の部材であり、ASA樹脂やABS樹脂等の合成樹脂が好適である。
A positioning member 10 is interposed between the upper outer column 3 and the lower outer column 4.
The positioning member 10 is a synthetic resin member, and a synthetic resin such as an ASA resin or an ABS resin is preferable.
図3および図4に示すように、この位置決め部材10は、枠材11とこの枠材11に設けられた保持部12とからなる。枠材11の形状は、図示の実施形態では環状であるが、内柱1や外柱2が断面多角形であれば、それに合った多角形状とされる。 As shown in FIGS. 3 and 4, the positioning member 10 includes a frame member 11 and a holding portion 12 provided on the frame member 11. The shape of the frame member 11 is an annular shape in the illustrated embodiment, but if the inner pillar 1 or the outer pillar 2 is a polygon in cross section, it is a polygonal shape suitable for it.
上記枠材11は上外柱3の下端縁と下外柱4の上端縁との間で挟持される。本実施形態において、保持部12は枠材11上に4カ所設けられており、円周方向等間隔に、つまり90°間隔に枠材11上で形成されている。なお、保持部12は3カ所でもよく、5カ所以上設けてもよいが、保持部12は枠材11に対し等間隔で設けることが望ましい。また、保持部12は、環状に連続して形成したものであってもよい。 The frame member 11 is sandwiched between the lower end edge of the upper outer column 3 and the upper end edge of the lower outer column 4. In the present embodiment, the holding portions 12 are provided at four places on the frame member 11 and are formed on the frame member 11 at equal intervals in the circumferential direction, that is, at intervals of 90 °. In addition, although the holding part 12 may be three places and may be provided five or more places, it is desirable to provide the holding parts 12 with respect to the frame material 11 at equal intervals. Further, the holding portion 12 may be continuously formed in a ring shape.
図5に示すように、前記枠材11の幅寸法W1は、上外柱3および下外柱4の幅寸法W2よりやや大きい寸法となっている。この結果、組み立てられた状態で、枠材11の外端面は上外柱3および下外柱4の外表面よりも、少し半径方向外側に突出することになる。さらに、枠材11の外端部は他の部分と比べて厚み(図4(B)に示す符号h11)がやや大きい寸法となっている。そのため、上外柱3および下外柱4の切断小口(上外柱3の下端面および下外柱4の上端面)を隠すことができ、外観が良くなる。また、切断小口の端面を処理しなくて済むので、加工の手間が省け、コストが下がる。 As shown in FIG. 5, the width dimension W1 of the frame member 11 is slightly larger than the width dimension W2 of the upper outer column 3 and the lower outer column 4. As a result, in the assembled state, the outer end face of the frame member 11 slightly protrudes radially outward from the outer surfaces of the upper outer pillar 3 and the lower outer pillar 4. Furthermore, the outer end portion of the frame member 11 has a slightly larger dimension (the symbol h11 shown in FIG. 4B) than the other portions. Therefore, the cutting edge of the upper outer column 3 and the lower outer column 4 (the lower end surface of the upper outer column 3 and the upper end surface of the lower outer column 4) can be hidden, and the appearance is improved. In addition, since it is not necessary to process the end face of the cutting edge, it is possible to save processing time and cost.
図示の保持部12は四角形の板状に形成されている。保持部12の厚さ(図4(B)に示す符号t12)は枠材11の断面厚さ(図4(B)に示す符号t11)の約半分位であって、保持部12の内面は枠材11の内面と面一になっており、保持部12の外面は枠材11の厚さ方向の中間位置から立上っている。 The illustrated holding portion 12 is formed in a rectangular plate shape. The thickness of the holding portion 12 (symbol t12 shown in FIG. 4B) is about half of the cross-sectional thickness of the frame member 11 (symbol t11 shown in FIG. 4B), and the inner surface of the holding portion 12 is The inner surface of the frame member 11 is flush with the inner surface of the frame member 11, and the outer surface of the holding portion 12 rises from an intermediate position in the thickness direction of the frame member 11.
図5において、内柱1と位置決め部材10は実線で示し、上外柱3は位置決め部材10の上に配置された状態を想像線で示している。なお、下外柱4は位置決め部材10の下方で上外柱3と同じ位置に配置されることになる。この図5に示すように、保持部12はその外面が上外柱3の下部内周面3aに接触し(同様に下外柱4の上部内周面にも接触し)、またこの保持片12の内面が内柱1の外周面1aに接触するように枠材11に設けられている。このように保持部12が接触することにより、内柱1に対して、上外柱3および下外柱4のガタツキを抑えることができる。 In FIG. 5, the inner pillar 1 and the positioning member 10 are indicated by solid lines, and the upper and outer pillars 3 are indicated by imaginary lines in a state of being disposed on the positioning member 10. The lower outer pillar 4 is disposed at the same position as the upper outer pillar 3 below the positioning member 10. As shown in FIG. 5, the holding portion 12 has an outer surface that contacts the lower inner peripheral surface 3a of the upper outer column 3 (also contacts the upper inner peripheral surface of the lower outer column 4). The frame member 11 is provided so that the inner surface 12 of the frame 12 contacts the outer peripheral surface 1 a of the inner column 1. In this way, the holding portion 12 comes into contact with the inner pillar 1, and the backlash of the upper outer pillar 3 and the lower outer pillar 4 can be suppressed.
位置決め部材10は合成樹脂製であって、アルミニウム等の金属に対し若干の変形をすることで密着することができる。つまり、上外柱3の重みによって、上外柱3の下端縁と下外柱4の上端縁に対してなじむ程度の変形が生じるので、上外柱3をガタつかせずに保持することができる。しかも、このように密着することによって、粉塵や雨水の侵入も抑止して内柱1の腐食を防止できる。 The positioning member 10 is made of synthetic resin, and can be brought into close contact with a metal such as aluminum by being slightly deformed. That is, the weight of the upper outer pillar 3 causes a deformation that is compatible with the lower edge of the upper outer pillar 3 and the upper edge of the lower outer pillar 4, so that the upper outer pillar 3 can be held without rattling. it can. In addition, the close contact makes it possible to prevent dust and rain water from entering and prevent the inner pillar 1 from corroding.
図1に示すように、下外柱4は内柱1にネジ5で固定されており、その上下方向の中心部が地表面GLに位置している。つまり、下外柱4は地中に埋設された部分と地上に露出した部分が存するように施工される。このようにすることで、勾配地盤であっても、地表面と外柱2の間に隙間が出来ず内柱1が見えないので外観が良くなる。 As shown in FIG. 1, the lower outer column 4 is fixed to the inner column 1 with a screw 5, and the vertical center of the lower outer column 4 is located on the ground surface GL. That is, the lower outer pillar 4 is constructed so that there is a portion buried in the ground and a portion exposed to the ground. By doing this, even in the case of graded ground, a gap can not be formed between the ground surface and the outer column 2, and the inner column 1 can not be seen, so the appearance is improved.
図1および図2に示す下外柱4の上端縁の高さ(外柱2の分割位置)hは、地表面GLから5〜60mmの間とするのが好ましく、30〜60mmの間とするのがより好ましい。
この寸法hは、地表面が傾斜している場合は、一番低い地表面からの高さである。この寸法hを大きくすれば、設置場所が傾斜している場合に傾斜角度が大きくても上外柱3のみの交換ができるが、むやみにh寸法を大きくすると、損傷部分が下外柱4に残る可能性が増え、上外柱3の交換による美観回復ができにくくなる。このような理由から、上記h寸法内であることが好ましく、この場合には交換による美観回復範囲が実用上充分大きくとれることになる。
The height (the dividing position of the outer column 2) h of the upper end of the lower outer column 4 shown in FIGS. 1 and 2 is preferably between 5 and 60 mm from the ground surface GL, and is between 30 and 60 mm. Is more preferable.
This dimension h is the height from the lowest ground surface when the ground surface is inclined. If this dimension h is increased, even if the installation location is inclined, even if the inclination angle is large, only the upper outer column 3 can be replaced, but if the h dimension is increased unreasonably, the damaged portion becomes the lower outer column 4 The possibility of remaining is increased, and it becomes difficult to recover the appearance by replacing the upper outer pillar 3. For these reasons, it is preferable to be within the h dimension. In this case, the aesthetic recovery range by replacement can be sufficiently large in practice.
本発明の車止めAでは、外柱2を上下に分割した構造を採ったため、車止めAを施工した後、経年変化や事故等により上外柱3に傷がついたり損傷が生じた場合は、古い上外柱3のみを抜き取って新しい上外柱3のみを差し込めばよい。このように新旧の上外柱3を交換することで、車止めAを美麗な状態に維持することができる。 In the car stop A of the present invention, since the outer pillar 2 is divided into upper and lower parts, when the upper outer pillar 3 is damaged or damaged due to secular change or accident after construction of the car stop A, it is old Only the upper outer pillar 3 may be removed and only the new upper outer pillar 3 may be inserted. By exchanging the old and new upper and outer pillars 3 in this way, the car stopper A can be maintained in a beautiful state.
上記のように、外柱2のうち上外柱3のみを下外柱4を残して取外すと、外柱2に傷が付いたときの交換が容易に行え、また埋設部分のハツリ工事が不要となり、設置場所が勾配地盤であっても上外柱3のみの交換で美感を維持できる。
しかも、下外柱4の下部が地中に固定されていることで、地表面と外柱2の間に隙間が出来ず内柱1が見えないので外観が良くなる。
As described above, when only the upper outer pillar 3 of the outer pillars 2 is removed except the lower outer pillar 4, replacement when the outer pillar 2 is damaged can be easily performed, and there is no need for a hatching work of the buried portion Thus, even if the installation location is a sloped ground, the aesthetics can be maintained by replacing only the upper and outer pillars 3.
Moreover, since the lower part of the lower outer pillar 4 is fixed to the ground, a gap can not be formed between the ground surface and the outer pillar 2 and the inner pillar 1 can not be seen, so the appearance is improved.
つぎに、図8に基づき車止めAの施行方法を説明する。
(車止めの施工方法)
(1)図8(1)は施工前の内柱1を示している。内柱1の上方部分には、縦方向に間隔をあけて2カ所のネジ孔が形成されている。図6にも示すように、このネジ孔に仮止めボルト6を螺合させることができる。手すり等を取り付ける予定のある場合は、図8(1)に示すように、内柱1のネジ孔に仮止めボルト6を螺合しておくとよい。
Below, the enforcement method of the vehicle stop A is demonstrated based on FIG.
(Construction method of car stopper)
(1) FIG. 8 (1) shows the inner pillar 1 before construction. Two screw holes are formed in the upper part of the inner pillar 1 at intervals in the vertical direction. As shown in FIG. 6, the temporary fixing bolt 6 can be screwed into the screw hole. If a handrail or the like is to be attached, it is preferable to screw the temporary fixing bolt 6 into the screw hole of the inner column 1 as shown in FIG. 8 (1).
(2)そして、図8(2)および図6に示すように、仮止めボルト6のネジ部にボルトキャップ7を取り付ける。 (2) Then, as shown in FIG. 8 (2) and FIG. 6, the bolt cap 7 is attached to the screw portion of the temporary fixing bolt 6.
(3)ついで、図8(3)に示すように、この内柱1に、下外柱4を固定し、位置決め部材10を取り付ける。また、内柱1の下端部に底板(図示省略)を取り付ける。
図6にも示すボルトキャップ7は、軟質塩化ビニル等の樹脂製の筒状のキャップであり、その内周面には雌ネジが切られた雌ネジ部7aを有している。そのため、後述の充填材を充填する際に、ボルトキャップ7が仮止めボルト6から抜け落ちるのを防止することができる。
さらに、基礎孔に内柱1を設置し、内柱1の内部にコンクリート(充填材a)を充填し、さらに図示してないが基礎孔にもコンクリートを充填する。
(3) Next, as shown in FIG. 8 (3), the lower outer pillar 4 is fixed to the inner pillar 1, and the positioning member 10 is attached. Further, a bottom plate (not shown) is attached to the lower end portion of the inner column 1.
The bolt cap 7 also shown in FIG. 6 is a cylindrical cap made of a resin such as soft vinyl chloride, and has an internal thread 7a having an internal thread cut on the inner peripheral surface thereof. Therefore, it is possible to prevent the bolt cap 7 from falling off from the temporary fixing bolt 6 when filling a filler described later.
Furthermore, the inner column 1 is installed in the foundation hole, the inside of the inner column 1 is filled with concrete (filling material a), and the foundation hole is also filled with concrete although not shown.
(4)コンクリートが硬化した後、図8(4)に示すように内柱1に上外柱3を固定する。手すり等を取り付ける場合は、上外柱3を固定する前に、仮止めボルト6を抜き取っておく。この場合、ボルトキャップ7のみ内柱1内に残留している状態となる。
通常は内柱1内にコンクリート(充填材a)を充填すると、ボルトを挿入するための空間が無くなるため、ボルト固定は困難となる。しかしながら、本実施形態のように、ボルトキャップ7を内柱1内に残留させておくことで、手すり等を固定するためのボルトを挿入するための空間が確保でき、ボルト固定が容易に行える。
(4) After the concrete is hardened, the upper and outer pillars 3 are fixed to the inner pillar 1 as shown in FIG. When attaching a handrail or the like, the temporary fixing bolt 6 is removed before the upper outer pillar 3 is fixed. In this case, only the bolt cap 7 remains in the inner column 1.
Normally, when concrete (filling material a) is filled in the inner pillar 1, there is no space for inserting bolts, so bolt fixing becomes difficult. However, as in the present embodiment, by leaving the bolt cap 7 in the inner column 1, a space for inserting a bolt for fixing a handrail or the like can be secured, and the bolt can be fixed easily.
(5)内柱1内にはボルトキャップ7により、固定用ボルト8を挿入するための空間が形成されているので、車止めAに手すり21等を取付ける必要が生じたときは、手すり21のブラケット22と外柱2の挿通孔に固定用ボルト8を通し、この固定用ボルト8を内柱1のネジ孔にねじ込むことができる。このようにして図8(5)に示すように、いつでも手すり21等の取付けが可能となる。 (5) Since a space for inserting the fixing bolt 8 is formed by the bolt cap 7 in the inner column 1, when it becomes necessary to attach the handrail 21 or the like to the car stop A, the bracket of the handrail 21 The fixing bolt 8 can be passed through the insertion holes 22 and 22 of the outer column 2 and screwed into the screw holes of the inner column 1. In this way, as shown in FIG. 8 (5), the handrail 21 or the like can be attached at any time.
図7は、手すり21を取付けた状態の車止めAを示している。図示のごとく、本実施形態によれば、固定用ボルト8は内柱1に形成されているネジ孔にねじ込むことで固定される。なお、固定ボルト8の先端のネジ部はボルトキャップ7内に挿入される。このボルトキャップ7は樹脂製であるので、固定用ボルト8のネジ溝より柔らかく、ある程度の変形が可能なため、固定用ボルト8となじみやすく固定用ボルト8の挿入が容易に行える。 FIG. 7 shows the car stop A with the handrail 21 attached. As illustrated, according to the present embodiment, the fixing bolt 8 is fixed by being screwed into a screw hole formed in the inner pillar 1. The screw portion at the tip of the fixing bolt 8 is inserted into the bolt cap 7. Since the bolt cap 7 is made of resin, it is softer than the screw groove of the fixing bolt 8 and can be deformed to some extent. Therefore, the bolt cap 7 can easily fit into the fixing bolt 8 and can be easily inserted.
このようにして、車止めAに手すり21を取付けることができる。この手すり21の取付けは、車止めAの施工時にも行えるが、車止めA施工後において事後的にも行える。 Thus, the handrail 21 can be attached to the car stop A. Although this handrail 21 can be attached at the time of construction of the car stopper A, it can also be performed after the construction of the car stopper A.
本発明の車止めは、自動車の進入禁止区域の表示や自動車の強制停止機能を主たる用途とするが、これら以外にも、自動車等の転落防止(立体駐車場や海岸)など様々な用途に利用することができる。 The car stop according to the present invention is mainly used to display the entry prohibited area of the car and the forced stop function of the car, but in addition to these, it is used for various uses such as prevention of falling of cars etc. be able to.
