以下、本発明の実施形態の構成を、図面を参照して説明する。ただし、本発明の範囲は、図示例に限定されるものではない。   Hereinafter, the configuration of an embodiment of the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples.

図１は、本実施形態に係る車両用防護柵１に用いられる支柱１０を例示する斜視図である。
図１に例示すように、支柱１０は、垂直板２０及びベースプレート３０を有する。支柱１０は、金属部材により構成される。支柱１０は、例えば、溶接により垂直板２０及びベースプレート３０を接合される。支柱１０は、垂直板２０及びベースプレート３０により構成されるため、接合箇所を最小限にすることができ容易に製作することができる。 FIG. 1 is a perspective view illustrating a column 10 used in a vehicle guard fence 1 according to this embodiment.
As illustrated in FIG. 1, the column 10 includes a vertical plate 20 and a base plate 30. The support | pillar 10 is comprised with a metal member. The column 10 is joined to the vertical plate 20 and the base plate 30 by welding, for example. Since the support | pillar 10 is comprised with the vertical board 20 and the baseplate 30, a joining location can be minimized and it can manufacture easily.

垂直板２０は、ビーム取付部２２、貫通孔２４、及び、くびれ２６を有する。
垂直板２０は、水平断面がI字形となるよう構成される。すなわち、垂直板２０は、１枚の金属板であり、フラットな形状を有する。垂直板２０は、上端からベースプレート３０と接合する下端にかけて広くなるように、くびれ２６の有する側壁を傾斜させて形成される。垂直板２０は、くびれ２６の有する側壁とは反対の側壁に、ビーム取付部２２を有する。本実施形態の垂直板２０は、ビーム取付部２２を２ヵ所備えたものを例示して説明する。 The vertical plate 20 has a beam attachment portion 22, a through hole 24, and a constriction 26.
The vertical plate 20 is configured to have an I-shaped horizontal cross section. That is, the vertical plate 20 is a single metal plate and has a flat shape. The vertical plate 20 is formed by inclining the side wall of the constriction 26 so as to increase from the upper end to the lower end joined to the base plate 30. The vertical plate 20 has a beam attachment portion 22 on the side wall opposite to the side wall of the constriction 26. The vertical plate 20 of the present embodiment will be described with an example in which two beam mounting portions 22 are provided.

ビーム取付部２２は、パイプ状の横梁（ビーム５）を取り付けるための設置部である。ビーム取付部２２は、円弧の形状を有しているがこれに限定するものではなく、ビーム５の形状に合わせて設けてよい。また、ビーム取付部２２は、ビーム５を形状加工して取り付けられてもよい。   The beam attachment portion 22 is an installation portion for attaching a pipe-shaped horizontal beam (beam 5). The beam attachment portion 22 has a circular arc shape, but is not limited thereto, and may be provided according to the shape of the beam 5. Further, the beam attachment portion 22 may be attached by processing the shape of the beam 5.

貫通孔２４は、垂直板２０に複数の孔を穿設される。貫通孔２４は、重量の軽減や材料の削減の効果がある。また、貫通孔２４は、衝撃を受けることにより塑性変形を容易にし、塑性変形することによって衝撃をより吸収することが期待できる。貫通孔２４は、孔の形状、孔の数、孔の大きさ及び穿設場所を適宜に変更することができる。   The through hole 24 is formed with a plurality of holes in the vertical plate 20. The through hole 24 has an effect of reducing weight and reducing material. Further, the through-hole 24 can be expected to facilitate plastic deformation by receiving an impact and to absorb the impact more by plastic deformation. The through-hole 24 can change the shape of a hole, the number of holes, the size of a hole, and a drilling place suitably.

くびれ２６は、受け付けた衝撃により垂直板２０を屈曲させるためのものである。くびれ２６は、垂直板２０を局部的に屈曲させることにより、衝撃を軽減することができる。   The constriction 26 is for bending the vertical plate 20 by the received impact. The constriction 26 can reduce the impact by bending the vertical plate 20 locally.

ベースプレート３０は、垂直板２０を立てた状態で地面に固定するための固定部材である。ベースプレート３０は、路肩上に取り付けるためのボルト孔３２を有し、固定手段としてアンカーボルトやボルト及びナットなどにより固定される。ベースプレート３０は、大きさや形状を適宜に変更することができる。
ベースプレート３０は、高架橋などのコンクリート上に固定されてもよいし、アスファルト上に固定されてもよいし、土に固定されてもよい。すなわち、本例の車両用防護柵１は、高架橋だけでなく、一般のガードレールなどとして利用されてもよい。 The base plate 30 is a fixing member for fixing the vertical plate 20 to the ground in a standing state. The base plate 30 has bolt holes 32 for mounting on the road shoulder, and is fixed by anchor bolts, bolts, nuts, or the like as fixing means. The base plate 30 can be appropriately changed in size and shape.
The base plate 30 may be fixed on concrete such as a viaduct, may be fixed on asphalt, or may be fixed on soil. That is, the vehicle guard fence 1 of this example may be used not only as a viaduct but also as a general guardrail or the like.

図２は、本実施形態に係る車両用防護柵１の設置例を説明する図である。
図３は、図２の側面視を例示する図である。
図２に例示する車両用防護柵１は、ビーム５が連続するように路肩上に設置されるが、便宜上、車両用防護柵１の一部に着目して説明する。
図２及び図３に例示するように、車両用防護柵１は、支柱１０が路肩等の路面上に固定され、固定された支柱１０がビーム５を支持するよう設置される。支柱１０は、ビーム取付部２２を車道側となるように配置され、ボルト３４によって固定される。ビーム取付部２２には、上段にビーム５ａを設置され、下段にビーム５ｂを設置される。ビーム取付部２２は、例えば、ボルトやナットによりビーム５を固定される。
複数のビーム５が端部で連結され、路面から一定の高さで支柱１０により支持された状態で、延伸している。ビーム５の連結は、連結具によってビーム５の端部同士を直接連結してもよいし、支柱１０が２つのビーム５の端部が固定することにより、間接的にビーム５を連結してもよい。 FIG. 2 is a diagram for explaining an installation example of the vehicle fence 1 according to the present embodiment.
FIG. 3 is a diagram illustrating a side view of FIG. 2.
The vehicle fence 1 illustrated in FIG. 2 is installed on the road shoulder so that the beam 5 is continuous. For convenience, the vehicle fence 1 will be described by focusing on a part of the vehicle fence 1.
As illustrated in FIGS. 2 and 3, the vehicle guard fence 1 is installed such that the support column 10 is fixed on a road surface such as a road shoulder, and the fixed support column 10 supports the beam 5. The support column 10 is disposed so that the beam mounting portion 22 is on the roadway side, and is fixed by a bolt 34. The beam mounting portion 22 is provided with the beam 5a at the upper stage and the beam 5b at the lower stage. The beam mounting portion 22 is fixed with the beam 5 by, for example, a bolt or a nut.
A plurality of beams 5 are connected to each other at the end, and are extended in a state where they are supported by the column 10 at a certain height from the road surface. The beam 5 may be connected by directly connecting the ends of the beams 5 with a connector, or the column 5 may be connected indirectly by fixing the ends of the two beams 5. Good.

図４は、衝突後の塑性変形した車両用防護柵を例示する図である。
図５は、車両用防護柵が全体で衝突エネルギーを吸収する様子を模式的に表す図である。
図４に例示するように、車両用防護柵は、車両により衝突される。このとき、ビーム５及び支柱１０は、衝突した衝撃により変形させられる。
ここで、支柱１０は、支柱１０ａ及び支柱１０ｂに区別し、支柱１０ａに着目して説明する。また、車両は、車両用防護柵に対して衝突エネルギーＦの方向に追突したものとして説明する。 FIG. 4 is a diagram illustrating a vehicle guard fence that has undergone plastic deformation after a collision.
FIG. 5 is a diagram schematically illustrating how the vehicular protective fence absorbs collision energy as a whole.
As illustrated in FIG. 4, the vehicle guard fence is collided by the vehicle. At this time, the beam 5 and the support column 10 are deformed by the impact that collided.
Here, the column 10 will be described by focusing on the column 10a while distinguishing between the column 10a and the column 10b. In addition, the vehicle will be described as having collided in the direction of the collision energy F with respect to the vehicle protective fence.

ビーム５は、車両が衝突した場合に、連続して横設されることによって柔軟性を高められ、衝突エネルギーＦを軽減させる。この時、ビーム５は、防護ネットのような役割を担う。
より具体的には、ビーム５を支持する支柱１０は、I字形状を有するため、ビームが連続する方向に変形しやすい。そのため、図５に示すように、連続する複数のビーム５全体が衝突エネルギーＦによって衝突位置に引っ張られ、支柱１０が、このビーム５の引っ張りに対して、柔軟に変形し（すなわち、ビームの連続方向に曲がり）、車両用防護柵１全体で衝突エネルギーＦを吸収する。
さらに、衝突位置の近傍にある支柱１０のくびれ２６は、局部的に屈曲させられることにより衝撃を軽減する。また、貫通孔２４は、孔の形状を変形させられることにより衝撃を軽減する。 When the vehicle collides, the beam 5 is continuously laid sideways to increase flexibility and reduce the collision energy F. At this time, the beam 5 plays a role like a protective net.
More specifically, since the column 10 that supports the beam 5 has an I shape, it is likely to be deformed in the direction in which the beam continues. Therefore, as shown in FIG. 5, the entire plurality of continuous beams 5 are pulled to the collision position by the collision energy F, and the column 10 is deformed flexibly with respect to the tension of the beam 5 (that is, the continuation of the beams). Bend in the direction), and the vehicle's protective fence 1 as a whole absorbs the collision energy F.
Furthermore, the constriction 26 of the support | pillar 10 in the vicinity of a collision position reduces an impact by being bent locally. Moreover, the through-hole 24 reduces an impact by changing the shape of the hole.

このように、支柱１０を効率的に製作することにより、車両用防護柵１を屈曲しやすくすることができる。また、車両用防護柵を屈曲性の向上により車両の衝突時の衝撃を軽減し、車両の破損や車両乗員の障害を最小限に抑えることができる。   Thus, by efficiently manufacturing the column 10, the vehicle guard fence 1 can be easily bent. In addition, by improving the flexibility of the vehicular protective fence, it is possible to reduce the impact at the time of the collision of the vehicle, and to minimize the damage of the vehicle and the obstacle of the vehicle occupant.

以上説明したように、本実施形態に係る車両用防護柵１によれば、支柱１０を垂直板２０及びベースプレート３０で製作することにより、接合箇所の軽減や製作時間の短縮を実現することができる。また、車両用防護柵は、垂直板２０に貫通孔２４を穿設されることにより、軽量化を図れるとともに屈曲性を向上させ衝撃を軽減することができる。また、車両用防護柵は、支柱１０を垂直板２０及びベースプレート３０で製作することにより、変形後の交換も素早く行うことができる。
以上、本発明に係る実施形態について説明したが、これらに限定されるものではなく、発明の趣旨を逸脱しない範囲内において、種々の変更、追加等が可能である。 As described above, according to the guard fence 1 for a vehicle according to the present embodiment, it is possible to reduce the number of joints and the manufacturing time by manufacturing the support column 10 with the vertical plate 20 and the base plate 30. . In addition, the vehicular guard fence can be reduced in weight by being provided with the through hole 24 in the vertical plate 20, and can be improved in flexibility and reduced in impact. Moreover, the protection fence for vehicles can also perform the replacement | exchange after a deformation | transformation quickly by manufacturing the support | pillar 10 with the vertical board 20 and the base plate 30.
