Description
本発明は、車止めに関する。さらに詳しくは、本発明は、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車止めに関する。 The present invention relates to a car stop. More specifically, the present invention relates to a car stop that has the function of displaying a prohibited area for automobiles and forcibly stopping the automobile.
特許文献１の従来技術は、駐車場の路盤中にほぼ垂直に植え込まれる二本の杭棒部分と、路盤より突き出た二本の杭棒部分の上端部にほぼ直角に連結された水平連結棒部分とからなる車止め部材である。杭棒部分および水平連結棒部分は鉄筋や鋼棒などを用いた金属棒で構成したものである。
しかるに、この従来技術は、中実の金属棒（鋼棒）を用いるため、重量が重いという欠点がある。
The prior art disclosed in Patent Document 1 consists of two pile rods that are implanted almost vertically into the roadbed of a parking lot, and a horizontal connection that is connected almost perpendicularly to the upper ends of the two pile rods that protrude from the roadbed. This is a car stopper member consisting of a rod part. The pile rod part and the horizontal connecting rod part are made of metal rods using reinforcing bars, steel rods, etc.
However, this conventional technique uses a solid metal rod (steel rod), so it has the disadvantage of being heavy.
特許文献２の従来技術は、金網柵などに用いられる支柱用鋼管であり、補強パイプの外面上における放射位置に多数のスペーサを縦方向に溶接一体化することにより補強部材を形成し、この補強部材を管本体の内部に挿入して、スペーサの下端を管本体の下端開口部を通じてその内面に溶接一体化したものである。
しかるに、この従来技術は、多数のスペーサ（金属円柱）を溶接にて固着するため、製作工数が非常に多くかかるという問題がある。また、溶接付けを用いていることから線膨張係数の異なる材料を使用することができない。さらに、溶接付けした部分は腐食が生じやすいため、腐食を防止するためのメッキ処理または、防サビ剤の塗布が必要になり、手間と製造コストがかかる。
The prior art disclosed in Patent Document 2 is a steel pipe for a support used in a wire mesh fence, etc., and a reinforcing member is formed by vertically welding a large number of spacers at radial positions on the outer surface of a reinforcing pipe. The member is inserted into the tube body, and the lower end of the spacer is integrally welded to the inner surface of the tube body through the lower end opening of the tube body.
However, this conventional technique has a problem in that a large number of spacers (metal cylinders) are fixed by welding, which requires a very large number of manufacturing steps. Furthermore, since welding is used, materials with different coefficients of linear expansion cannot be used. Furthermore, since the welded parts are prone to corrosion, it is necessary to perform plating or apply an anti-rust agent to prevent corrosion, which increases labor and manufacturing costs.
特許文献３の従来技術は、建築鉄骨や道路標識、自転車・バイクのフレームなどに汎用的に用いられる管体の補強材である。
補強材は放射状の板材からなるもので、この補強材を対向して配置した２本の管体の接合部分に挿入して用いられる。
しかるに、この従来技術は補強材を差し込むだけで特別の固定手段は用いられていない。したがって、縦向きで用いられたとき落下の可能性があり、車止めに使った場合に基礎のコンクリートに接触すると、補強材が腐食するという欠点がある。
The prior art disclosed in Patent Document 3 is a reinforcing material for tubular bodies that is commonly used for building steel frames, road signs, bicycle/motorcycle frames, and the like.
The reinforcing material is made of radial plate material, and is used by inserting it into the joining portion of two tubes arranged opposite each other.
However, in this prior art, only the reinforcing material is inserted and no special fixing means is used. Therefore, when used vertically, there is a possibility of falling, and when used as a car stop, the reinforcing material corrodes if it comes into contact with the concrete of the foundation.
本発明は上記事情に鑑み、軽量で製作容易であり腐食を防止できる車止めを提供することを目的とする。 In view of the above circumstances, an object of the present invention is to provide a car stop that is lightweight, easy to manufacture, and capable of preventing corrosion.
第１発明の車止めは、中空であり金属製の車止め本体と、前記車止め本体の内部に挿入される補強部材と、該補強部材を保持するための保持材とを備える車止めであって、前記補強部材は、横断面視において点対称の部材であって、中心から外側に向かって放射状に延びる６～１０枚の板材からなり、前記補強部材は、前記車止め本体における地中に埋設される埋設部と地上に露出する露出部とにわたり、かつ前記埋設部ではその１／５～４／５にわたって配置されており、前記補強部材は、その下端部が前記車止め本体の下端部より上位で保持されており、前記保持材は前記車止め本体に差し込まれたピン状の部材または棒状の部材であって、前記補強部材の下端部を支持していることを特徴とする。
第２発明の車止めは、第１発明において、前記補強部材は、横断面視において、前記車止め本体の内壁面に最接近する部分が点当たり形状に形成されていることを特徴とする。
第３発明の車止めは、第１または第２発明において、前記補強部材が、アルミニウムの押出形材であることを特徴とする。
A car stop according to a first aspect of the invention includes a hollow metal car stop main body, a reinforcing member inserted into the inside of the car stop main body, and a holding member for holding the reinforcing member. The member is a point-symmetrical member in a cross-sectional view, and is composed of 6 to 10 plates extending radially outward from the center, and the reinforcing member is a buried portion of the car stopper body that is buried underground. and an exposed part exposed above the ground , and is arranged over 1/5 to 4/5 of the buried part, and the reinforcing member is held such that its lower end is higher than the lower end of the car stop main body. The holding member is a pin-like member or a rod-like member inserted into the car stopper body, and supports the lower end portion of the reinforcing member .
The car stop of a second invention is characterized in that, in the first invention , the reinforcing member is formed in a dotted shape at a portion closest to the inner wall surface of the car stop main body in a cross-sectional view.
A third aspect of the vehicle stopper according to the first or second aspect is characterized in that the reinforcing member is an extruded aluminum member.
第１発明によれば、つぎの効果を奏する。
ａ）補強部材が放射状に延びる６～１０枚の板材を有するので、車止め本体の周りのどの方向から外力が加わっても、大きな抵抗力を発揮することができる。したがって、車止めの強制停止機能を高めることができる。
ｂ）車等の衝突による外力が生じても、補強部材の下端部が地表面より上部に移動することがなく、最も外力が加わる地表面付近の衝突抵抗力を高めることができる。
ｃ）補強部材の下端部が車止め本体の下端部より上位にあることで、埋設部に用いられるコンクリートと補強部材の下端部との間に空間ができ、補強部材がコンクリートに接触することがない。このため、補強部材の材質がアルカリ腐食しやすいものであっても、腐食を防止することができる。
ｄ）補強部材は車止め本体に差し込まれたピン状の部材または棒状の部材によって、その下端部が支えられているので、車止めの施工時に補強部材が落下することはなく作業性が良くなる。また、補強部材を溶接等により車止め本体へ固定する必要がなく生産性が向上する。
第２発明によれば、補強部材の先端部が点接触形状（点当たり形状）であるため、補強部材の先端部と車止め本体の内周面（内壁面）との接点を減らすことができ、補強部材の車止め本体への挿入が容易に行える。
第３発明によれば、アルミニウムの押出形状を用いると、軽量でかつ寸法精度の高い補強部材が得られる。このため、車止めの組立が容易となる。
According to the first invention, the following effects are achieved.
a) Since the reinforcing member has 6 to 10 plates extending radially, it can exert a large resistance force even if external force is applied from any direction around the car stop body. Therefore, the forced stop function of the car stop can be enhanced.
b) Even if an external force is generated due to a collision of a car or the like, the lower end of the reinforcing member does not move above the ground surface, and the collision resistance near the ground surface where the external force is most applied can be increased.
c) By placing the lower end of the reinforcing member higher than the lower end of the car stopper body, a space is created between the concrete used for the buried part and the lower end of the reinforcing member, and the reinforcing member does not come into contact with the concrete. . Therefore, even if the material of the reinforcing member is susceptible to alkali corrosion, corrosion can be prevented.
d) Since the lower end of the reinforcing member is supported by a pin-like member or a rod-like member inserted into the car stopper body , the reinforcing member does not fall during construction of the car stopper, improving workability. Further , there is no need to fix the reinforcing member to the car stopper body by welding or the like, which improves productivity .
According to the second invention, since the tip of the reinforcing member has a point contact shape (point-contact shape), the number of points of contact between the tip of the reinforcing member and the inner peripheral surface (inner wall surface) of the car stop body can be reduced; The reinforcing member can be easily inserted into the car stopper body.
According to the third invention, by using an extruded aluminum shape, a reinforcing member that is lightweight and has high dimensional accuracy can be obtained. Therefore, assembly of the car stop becomes easy.
つぎに、本発明の実施形態を図面に基づき説明する。
（第１実施形態）
図１および図２は、本発明の第１実施形態に係る車止めＡを示している。
この車止めＡは、車止め本体１と補強部材２Ａおよび保持材３とからなる。図示の車止め本体１は、１本の横中空管部１１とその両端に湾曲部分を介して接続された２本の縦中空管部１２，１３とからなる。つまり、図示の車止め本体１は逆Ｕ字形である。ただし、本発明には、車止め本体１の縦中空管部１２，１３の間にさらに横中空管部が接続された車止め本体や、横中空管部の両端に直角に縦中空管部が接続された車止め本体、縦向きに延びる縦中空管のみの車止め本体も含まれる。
Next, embodiments of the present invention will be described based on the drawings.
(First embodiment)
FIGS. 1 and 2 show a car stop A according to a first embodiment of the present invention.
This car stop A consists of a car stop main body 1, a reinforcing member 2A, and a holding member 3. The illustrated car stop main body 1 consists of one horizontal hollow tube section 11 and two vertical hollow tube sections 12 and 13 connected to both ends thereof via curved portions. That is, the illustrated car stopper body 1 has an inverted U-shape. However, the present invention includes a car stop main body in which a horizontal hollow pipe part is further connected between the vertical hollow pipe parts 12 and 13 of the car stop main body 1, and a vertical hollow pipe at right angles to both ends of the horizontal hollow pipe part. It also includes a car stop body with connected parts and a car stop body with only a vertical hollow tube extending vertically.
車止め本体１の材質としては、鉄やステンレス等の金属や、樹脂などが挙げられ、車止めＡの強度を確保する観点からは、鉄やステンレス等の金属が好ましい。金属を使用する場合、外表面には、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いてもよい。
横中空管部１１および縦中空管部１２，１３は、図１および図２に示したような断面が円形のもの以外に、断面が矩形のものであってもよい。
Examples of the material for the car stopper body 1 include metals such as iron and stainless steel, and resins, and from the viewpoint of ensuring the strength of the car stopper A, metals such as iron and stainless steel are preferable. When metal is used, the outer surface may be coated with plating or polyester powder baking coating for the purpose of preventing rust and the like.
The horizontal hollow tube section 11 and the vertical hollow tube sections 12 and 13 may have a rectangular cross section instead of having a circular cross section as shown in FIGS. 1 and 2.
車止め本体１は、地表面ＧＬより下方の地中に埋設される埋設部１ａと地表面ＧＬより上方の地上に露出する露出部１ｂとに分けられる。埋設部１ａは地中に形成したコンクリート基礎５内に埋め込まれている。
そして、補強部材２Ａは、前記車止め本体１を構成する縦中空管部１２，１３に挿入される。挿入された状態の補強部材２Ａの下端部は保持材３で支えられる（支持される）。
The car stopper main body 1 is divided into a buried part 1a buried in the ground below the ground surface GL and an exposed part 1b exposed above the ground above the ground surface GL. The buried portion 1a is embedded in a concrete foundation 5 formed underground.
Then, the reinforcing member 2A is inserted into the vertical hollow tube parts 12 and 13 that constitute the car stop main body 1. The lower end portion of the reinforcing member 2A in the inserted state is supported by the holding member 3.
車止め本体１の寸法に制限はなく、任意の寸法を採用できるが、代表的には、横幅Ｗ（図１（Ｂ）における左右の幅）が約７００～３０００ｍｍであり、高さＨ（図１（Ｂ）における上下の高さ）が約８００～１０５０ｍｍである。そして、埋設部１ａは約２５０～４００ｍｍである。図１の車止め本体１は、横幅Ｗが２０００ｍｍ、高さＨが８００ｍｍ、埋設部１ａが２５０ｍｍのものを示している。
基礎５は公知の構造であり、コンクリートを打設したコンクリート部５１とクラッシャラン５２とからなる。
There is no limit to the dimensions of the car stopper body 1, and any dimensions can be adopted, but typically the width W (left and right width in Fig. 1 (B)) is approximately 700 to 3000 mm, and the height H (Fig. 1 (Vertical height in (B)) is approximately 800 to 1050 mm. The buried portion 1a is approximately 250 to 400 mm. The car stopper body 1 shown in FIG. 1 has a width W of 2000 mm, a height H of 800 mm, and a buried portion 1a of 250 mm.
The foundation 5 has a known structure and consists of a concrete portion 51 in which concrete is poured and a crusher run 52.
補強部材２Ａは、既述のとおり縦中空管部１２，１３の下端部より挿入され、車止め本体１における埋設部１ａと露出部１ｂ（具体的には、縦中空管部１２，１３における埋設部１ａと露出部１ｂ）とにわたって配置される。そして、補強部材２Ａの下端部は、保持材３により車止め本体１の下端部（具体的には、縦中空管部１２，１３の下端部）よりも上位で保持されている。換言すれば、縦中空管部１２，１３の埋設部１ａを取りまく基礎のコンクリートと接触しないようにされている。
たとえば、補強部材２Ａの下端部と縦中空管部１２，１３の下端部との間は、５０ｍｍ以上であることが好ましく、１００ｍｍ以上であることがより好ましく、１５０ｍｍ以上であることがさらに好ましい。
The reinforcing member 2A is inserted from the lower end of the vertical hollow tube portions 12 and 13 as described above, and is inserted into the buried portion 1a and the exposed portion 1b of the vehicle stopper body 1 (specifically, between the vertical hollow tube portions 12 and 13). It is arranged across the buried part 1a and the exposed part 1b). The lower end portion of the reinforcing member 2A is held by the holding member 3 above the lower end portion of the car stopper body 1 (specifically, the lower end portions of the vertical hollow tube portions 12 and 13). In other words, the buried portions 1a of the vertical hollow tube portions 12 and 13 are prevented from coming into contact with the concrete of the foundation surrounding them.
For example, the distance between the lower end of the reinforcing member 2A and the lower end of the vertical hollow tube parts 12, 13 is preferably 50 mm or more, more preferably 100 mm or more, and even more preferably 150 mm or more. .
また、車止めＡの強度（強制停止機能）を高めるという観点から、補強部材２Ａの下端部と地表面ＧＬとの間（補強部材２Ａが埋設部１ａに配置される長さ）は、５０ｍｍ以上であることが好ましく、１００ｍｍ以上であることがより好ましく、１５０ｍｍ以上であることがさらに好ましい。補強部材２Ａがこのような位置で配置されていると、車等の衝突による外力が生じても、補強部材２Ａの下端部が地表面より上部に移動することがない。そのため、最も外力が加わる地表面付近の衝突抵抗力を高めることができる。 In addition, from the viewpoint of increasing the strength of the car stopper A (forced stop function), the distance between the lower end of the reinforcing member 2A and the ground surface GL (the length of the reinforcing member 2A placed in the buried part 1a) should be 50 mm or more. The length is preferably 100 mm or more, more preferably 150 mm or more. When the reinforcing member 2A is arranged in such a position, even if an external force is generated due to a collision with a car or the like, the lower end of the reinforcing member 2A will not move above the ground surface. Therefore, it is possible to increase the collision resistance near the ground surface where the external force is most applied.
したがって、本実施形態において、補強部材２Ａは、補強部材２Ａの下端部と地表面ＧＬとの間が５０ｍｍ～２００ｍｍとなる位置で配置することが好ましい。換言すれば、埋設部１ａの１／５～４／５程度にわたって補強部材２Ａを配置することが好ましい。 Therefore, in this embodiment, the reinforcing member 2A is preferably arranged at a position where the distance between the lower end of the reinforcing member 2A and the ground surface GL is 50 mm to 200 mm. In other words, it is preferable to arrange the reinforcing member 2A over about 1/5 to 4/5 of the buried portion 1a.
補強部材２Ａは、図４に示すように、中心０から外側に向かって放射状に延びる複数枚の板材を有する。その形状は横断面視において点対称の部材である。本明細書で「点対称」とは、補強部材の横断面の中心に対称点が存することを意味する。
本実施形態の補強部材２Ａは、横断面視で８枚の板材２１～２８が中心０（対称点）から外側に向かって放射状に延びた形状である。
As shown in FIG. 4, the reinforcing member 2A includes a plurality of plates extending radially outward from the center 0. Its shape is a member that is point symmetrical in cross-sectional view. As used herein, "point symmetry" means that a point of symmetry exists at the center of the cross section of the reinforcing member.
The reinforcing member 2A of this embodiment has a shape in which eight plates 21 to 28 extend radially outward from the center 0 (point of symmetry) when viewed in cross section.
この構造であると、車の衝突によって加わる外力が縦中空管部１２，１３の円周方向におけるどの位置から加わっても、充分大きな抵抗力を発揮する。
仮に、１枚の板材２１に真向から外力が加わると、その板材２１の座屈抵抗で外力を受け止めるが、座屈抵抗は大きいので、大きな抵抗力を発揮する。
また、２枚の板材２１，２２の間に外力が加わると、２枚の板材２１，２２の屈曲抵抗で外力を受け止めるが、屈曲抵抗の２枚分は大きいので、大きな抵抗力を発揮する。
With this structure, a sufficiently large resistance force is exerted even if the external force applied due to a car collision is applied from any position in the circumferential direction of the vertical hollow tube parts 12 and 13.
If an external force is applied directly to one plate 21, the external force will be absorbed by the buckling resistance of the plate 21, but since the buckling resistance is large, a large resistance force will be exerted.
Further, when an external force is applied between the two plates 21 and 22, the external force is received by the bending resistance of the two plates 21 and 22, but since the bending resistance of the two plates is large, a large resistance force is exerted.
補強部材２Ａを構成する板材の枚数は座屈抵抗の観点から、偶数であることが好ましい。
たとえば、板材の枚数は４枚から１２枚が好ましく、６～１０枚がより好ましく、８枚がさらに好ましい。板材がこのような枚数であると、高い衝突抵抗力を外力の方向に依存せずに発揮することができる。なお、板材の枚数が、４枚より下回ると対抗力に方向依存性が出てしまい、１２枚を越えると、重量が嵩み、コストが増加してしまう。
The number of plates constituting the reinforcing member 2A is preferably an even number from the viewpoint of buckling resistance.
For example, the number of plates is preferably 4 to 12, more preferably 6 to 10, and even more preferably 8. With such a number of plate materials, a high collision resistance force can be exerted without depending on the direction of external force. Note that if the number of plates is less than 4, the counterforce will be directionally dependent, and if it exceeds 12, the weight will increase and the cost will increase.
また、各板材２１～２８の先端部、つまり車止め本体１（縦中空管部１２，１３）の内壁面に最接近する部分は、点当たり形状に構成されている。
本明細書において点当たり形状とは、面当たりで接触する場合の接触面積よりも狭い面積で接触する形状をいう。補強部材２Ａ（具体的には、各板材２１～２８）の先端部を点当たり形状とすることで、補強部材２Ａの先端部と車止め本体１の内壁面との接点を減らすことができ、補強部材２Ａの車止め本体１（縦中空管部１２，１３）への挿入が容易に行える。
図４に示す本実施形態では、各板材２１～２８の先端部の横断面形状は、半円形に近い丸みを帯びた形状であるが、このほか三角形や台形状などであってもよい。
補強部材２Ａは、長さが約５００～７５０ｍｍであり、外径が縦中空管部１２，１３の内径（内壁面間の距離）より少し小さい大きさである。図１の補強部材２Ａは、長さが５００ｍｍのものを示している。
Further, the tip end portions of each of the plate members 21 to 28, that is, the portions closest to the inner wall surface of the car stopper body 1 (vertical hollow tube portions 12, 13) are configured in a dotted shape.
In this specification, the term "point-contact shape" refers to a shape that makes contact in an area narrower than the contact area in the case of surface-contact contact. By making the tip of the reinforcing member 2A (specifically, each plate material 21 to 28) into a dotted shape, the number of points of contact between the tip of the reinforcing member 2A and the inner wall surface of the car stopper body 1 can be reduced, and the reinforcement The member 2A can be easily inserted into the car stopper main body 1 (vertical hollow tube parts 12, 13).
In the present embodiment shown in FIG. 4, the cross-sectional shape of the tip of each of the plates 21 to 28 is a rounded shape close to a semicircle, but it may also be triangular, trapezoidal, or the like.
The reinforcing member 2A has a length of about 500 to 750 mm, and an outer diameter slightly smaller than the inner diameter (distance between inner wall surfaces) of the vertical hollow tube sections 12 and 13. The reinforcing member 2A in FIG. 1 has a length of 500 mm.
補強部材２Ａは、材料はアルミニウムで、製法は押出成形が好ましく用いられる。アルミニウムの押出形材は、重量が軽く、製造コストが低廉で、寸法精度が高いという利点がある。 The material of the reinforcing member 2A is aluminum, and extrusion molding is preferably used as the manufacturing method. Extruded aluminum profiles have the advantages of light weight, low manufacturing costs, and high dimensional accuracy.
保持材３は、図示の例はピン状の部材であるが、ナットの螺合が可能なボルト等の棒状の部材であってもよい。また、縦中空管部１２，１３内に挿入して基礎５の上面に置いただけの置物であってもよい。さらに、縦中空管部１２，１３の下端部を覆う蓋やキャップのような部材であってもよい。これらの保持材３の材料は、コンクリートに接触しても腐食しない材料であればよく任意に使用できる。これらの材料にはステンレス鋼や、プラスチックなどの樹脂製のものを例示できる。 The holding member 3 is a pin-shaped member in the illustrated example, but it may also be a rod-shaped member such as a bolt into which a nut can be screwed. Alternatively, the ornament may be simply inserted into the vertical hollow tube parts 12 and 13 and placed on the upper surface of the foundation 5. Furthermore, a member such as a lid or a cap that covers the lower end portions of the vertical hollow tube portions 12 and 13 may be used. Any material can be used for these holding members 3 as long as it does not corrode even when it comes into contact with concrete. Examples of these materials include stainless steel and resins such as plastics.
