図面を参照して、本発明の実施の形態を説明する。
実施の形態のガードレールは、車道の縁に沿って設けられ、又は、中央分離帯上に設けられる車両用防護柵であり、ステンレス製のコイルを絡み合わせて配列して構成した立体金網板1を、支柱3で支持して成る。
Embodiments of the present invention will be described with reference to the drawings.
The guard rail according to the embodiment is a vehicle guard fence provided along the edge of the roadway or on the central separation band, and includes a three-dimensional wire mesh plate 1 configured by intertwining stainless steel coils. The support 3 is supported.

図1(a)に示す第1の構成例のガードレールでは、立体金網板1の両横端の縦縁部15,15を、支柱3で支持して成る。また、図1(b)に示す第2の構成例のガードレールでは、立体金網板1の両横端の縦縁部15,15、及び、横方向略中央部150を、支柱3で支持して成る。   In the guard rail of the first configuration example shown in FIG. 1A, the vertical edge portions 15, 15 at both lateral ends of the solid metal mesh plate 1 are supported by the columns 3. Moreover, in the guard rail of the 2nd structural example shown in FIG.1 (b), the vertical edge parts 15 and 15 and the horizontal direction substantially center part 150 of both horizontal ends of the solid metal mesh board 1 are supported by the support | pillar 3. Become.

支柱3は、道路上の設置位置に設けられる基礎に固定される基部31と、該基部31から上方へ延設(立設)された長手状の取付部35から成る。この取付部35は、長手状の本体部350と、該本体部350の上下の各端部付近にて本体部表面から同じ方向へ突出するように設けられた支持具355,356と、該支持具355,356に対して着脱自在に設けられる金属製のロッド351とを有する。   The support column 3 includes a base 31 fixed to a foundation provided at an installation position on the road, and a longitudinal attachment 35 extending upward (standing) from the base 31. The attachment portion 35 includes a longitudinal main body portion 350, supports 355 and 356 provided so as to protrude in the same direction from the surface of the main body portion in the vicinity of the upper and lower ends of the main body portion 350, and the support And a metal rod 351 that is detachably attached to the tools 355 and 356.

立体金網板1は、コイル状のステンレス線材を、複数本、同一平面内で絡み合わせることにより配列するとともにコイル径20dに対応する厚み20t(図1(c))を具備せしめて成り、外形輪郭は縦横方形の平板状を成す。ここで、縦方向とは当該のガードレールが設置された状態での略鉛直方向を言い、横方向とは略水平方向を言う。また、立体金網板1では、上縁面から下方(金網内方)を見たとき、各所に下縁面まで貫通する見通し孔16(図1(c)参照)が構成されるように、各コイルが配列されている。特に、本実施の形態では、縦方向と横方向にコイルが配列されており、縦方向に配列されているコイル21(21a,21b)の軸芯21AX(21AXa,21AXb;図2(b)参照)が、見通し孔16の軸芯に略合致されている。   The three-dimensional wire mesh plate 1 is formed by arranging a plurality of coiled stainless wire rods by entwining them in the same plane and having a thickness 20t (FIG. 1 (c)) corresponding to the coil diameter 20d. Is in the form of a vertical and horizontal flat plate. Here, the vertical direction refers to a substantially vertical direction in a state where the guard rail is installed, and the horizontal direction refers to a substantially horizontal direction. Further, in the three-dimensional wire mesh plate 1, each of the line-of-sight holes 16 (see FIG. 1 (c)) penetrating to the lower edge surface is formed in each place when viewed downward (inward of the wire mesh) from the upper edge surface. Coils are arranged. In particular, in the present embodiment, coils are arranged in the vertical direction and the horizontal direction, and the axial cores 21AX (21AXa, 21AXb; see FIG. 2B) of the coils 21 (21a, 21b) arranged in the vertical direction. ) Is substantially matched with the axis of the line-of-sight hole 16.

この見通し孔16にロッド351を挿通した状態で、ロッド351の上下の端部を、支持具355,356で固定する(図1(d)等参照)ことにより、立体金網板1は支柱3に取り付けられる。上述のように、見通し孔16は、上縁面/下縁面の各所に構成されている(横並びに構成されている;図1(c)参照)ため、支柱3は、立体金網板1の両横端の縁部15のみならず、横方向の任意の位置、例えば、図1(b)の如く横方向略中央部150に取り付けることも可能である。このため、例えば、道路状況(カーブ等)等に応じて適宜に湾曲させるとともに、適宜の位置に支柱を増設して強度を確保することも可能となる。また、見通し孔16に挿通したロッド351を支持具355,356で固定することにより立体金網板1を支柱に取り付けるため、支柱回りで外部に出っ張る部材を無くすことができ、当該の出っ張りが歩行者等に危害を及ぼす恐れも無くすことができる。また、車両の衝突等により損傷した場合でも、支柱3を残して立体金網板1のみを取り替えたり、損傷の程度によっては立体金網板1を溶接等の簡易な手法で修復することも可能であるため、コストを低減でき、メンテナンスも容易となる。また、厚さ20tのある立体金網板1を防護壁として用いているため、平面的な金網を用いる場合と比較して、優れた衝撃吸収性能や、耐久性能を発揮できる。また、立体金網板1であるため、波形断面のビーム等を防護壁として用いる場合のような経年劣化による色落ちも無い。また、設置場所の自然環境等に応じて、軟質樹脂等で被覆した線材をコイルに用いることにより、耐久性を更に高めるようにしてもよい。   With the rod 351 inserted into the line-of-sight hole 16, the upper and lower ends of the rod 351 are fixed by the support tools 355 and 356 (see FIG. It is attached. As described above, the line-of-sight holes 16 are configured at various locations on the upper edge surface / lower edge surface (configured side by side; see FIG. 1C). It is possible to attach not only to the edge portions 15 at both lateral ends but also to an arbitrary position in the lateral direction, for example, the substantially central portion 150 in the lateral direction as shown in FIG. For this reason, for example, it is possible to bend appropriately according to the road condition (curve or the like) or the like, and to add strength to an appropriate position to ensure strength. Moreover, since the solid metal mesh board 1 is attached to a support | pillar by fixing the rod 351 inserted in the line-of-sight hole 16 with the support tools 355 and 356, the member protruding outside around the support | pillar can be eliminated, and the said protrusion is a pedestrian. It is possible to eliminate the risk of harm to the like. Further, even when the vehicle is damaged due to a vehicle collision or the like, it is possible to leave the support column 3 and replace only the solid metal mesh plate 1 or to repair the solid metal mesh plate 1 by a simple method such as welding depending on the degree of damage. Therefore, cost can be reduced and maintenance is easy. In addition, since the solid metal mesh plate 1 having a thickness of 20 t is used as a protective wall, superior shock absorbing performance and durability performance can be exhibited as compared with the case of using a flat metal mesh. Moreover, since it is the solid metal mesh board 1, there is no color fading due to aged deterioration as in the case where a beam having a corrugated cross section is used as a protective wall. Further, the durability may be further improved by using a wire coated with a soft resin or the like for the coil in accordance with the natural environment of the installation place.

なお、上記では、金属製のロッド351を用いているが、ロッドに代えて、例えば、樹脂製/金属製/ゴム製/炭素繊維等の繊維強化材製等のケーブルを用いるようにしてもよい。さらには、これらを組み合わせた材質のロッド(棒材)やケーブル若しくはワイヤーロープや、複合材(例:金属と強化ゴムの複合材)製のロッド(棒材)やケーブル若しくはワイヤーロープを用いてもよい。また、棒状材表面が軟質樹脂等で被覆されたり、塗装されたものでもよい。
また、上記では、1支柱当たり1本のロッド351を用いて立体金網板1を支柱3に取り付けているが、支柱3の取付部から張り出すように突設させる支持具355,356の突出量を長くする等して、2本以上のロッドを用いて取り付けるようにして、強度を高めてもよい。
In the above description, the metal rod 351 is used. However, instead of the rod, for example, a cable made of resin / metal / rubber / fiber reinforced material such as carbon fiber may be used. . Furthermore, rods (bars), cables or wire ropes made of a combination of these materials, rods (bars) made of composite materials (eg, composite materials of metal and reinforced rubber), cables or wire ropes may also be used. Good. Further, the surface of the rod-shaped material may be coated or coated with a soft resin or the like.
Further, in the above, the solid metal mesh plate 1 is attached to the support column 3 using one rod 351 per support column, but the protruding amounts of the support tools 355 and 356 that protrude from the mounting portion of the support column 3 are projected. For example, the strength may be increased by increasing the length of the rod by using two or more rods.

ところで、上述のように、本実施の形態では、コイルを縦方向と横方向に配列しているが、縦横に配列する手法としては、図3(b)のように、縦方向と横方向に密に配列する手法、即ち、縦方向のコイルの全てを隣接する縦方向のコイルとコイル縁部205で絡み合わせるとともに横方向のコイルの全てを隣接する横方向のコイルとコイル縁部205で絡み合わせる手法の他、図3(c)のように縦方向の配列に隙間(縦方向のコイルを設けない部位)を設ける手法、図3(d)のように横方向の配列に隙間(横方向のコイルを設けない部位)を設ける手法、図3(e)のように縦方向と横方向の配列に隙間を設ける手法がある。このように、適宜に隙間を設けることもできるため、それにより、ガードレールの向こう側の景色等の視認性を向上させることができ、観光地等では、必要に応じて適宜の部位に隙間を設けたガードレールを用いることができる。
また、隙間を設ける手法は、上記手法に限らず、例えば、徐々に隙間の設け方を変化させることにより、上方側の視認性が徐々に高く、下方側の視認性が徐々に低くなるようにグラデーションを設ける手法であってもよい。
なお、本実施の形態とは異なり、コイルを縦横方向ではなく斜め方向に配列する場合には、斜め方向に於いて上記と同様に隙間を設けることができる。
Incidentally, as described above, in this embodiment, the coils are arranged in the vertical direction and the horizontal direction. However, as a method of arranging the coils in the vertical direction and the horizontal direction, as shown in FIG. Closely arranged, that is, all longitudinal coils are entangled with adjacent longitudinal coils and coil edges 205 and all lateral coils are entangled with adjacent lateral coils and coil edges 205. In addition to the matching method, a method of providing gaps (portions where no vertical coils are provided) in the vertical arrangement as shown in FIG. 3C, and a gap (horizontal direction) in the horizontal arrangement as shown in FIG. There are a method of providing a portion where no coil is provided, and a method of providing a gap in the vertical and horizontal arrangements as shown in FIG. As described above, since a gap can be provided as appropriate, it is possible to improve the visibility of the scenery or the like beyond the guardrail, and in a sightseeing spot or the like, a gap is provided at an appropriate part as necessary. A guardrail can be used.
Further, the method of providing the gap is not limited to the above method, and for example, by gradually changing the method of providing the gap, the upper visibility is gradually increased and the lower visibility is gradually decreased. A technique of providing gradation may also be used.
Unlike the present embodiment, when the coils are arranged in an oblique direction rather than a longitudinal and lateral direction, a gap can be provided in the oblique direction as described above.

先述の「複数本のコイルを同一平面内で絡み合わせることにより配列する」とは、例えば、図2(a)の如く横方向に隣接して設けたコイル22a,22bを両者のコイル縁部205で絡み合わせて横方向に配列することや、図2(b)の如く縦方向に隣接して設けたコイル21a,21bを両者のコイル縁部205で絡み合わせて縦方向に配列することを言い、斜め方向に於いて同様に絡み配列したものであってもよい。これら交差する方向のコイル群内の任意のコイルと任意のコイルは、さらに、図2(c)の如くそれぞれの絡み位置22i,21iにて重複して絡み合わせられており、それにより、重複絡み位置20ipが構成されている。なお、各コイル状線材は、その端部で折り返されて、当該のコイルと交差する方向のコイル(最縁側のコイル)に係止されている。このように構成されて、立体金網板1は、コイル径20dに相当する厚み20tを有する平板状の外形輪郭を成す。なお、真円筒の周面上に巻回して成る形状のコイルの場合は厚み20tはコイル径20dと略同等であるが、楕円筒の周面上に巻回して成る形状のコイルの場合は、楕円の形状に応じて決まる厚みとなることは勿論である。   The above-mentioned “arranging a plurality of coils by intertwining them in the same plane” means that, for example, coils 22 a and 22 b provided adjacent in the horizontal direction as shown in FIG. 2 and the coils 21a and 21b provided adjacent to each other in the vertical direction as shown in FIG. 2B are entangled at both coil edges 205 and arranged in the vertical direction. In the diagonal direction, they may be similarly entangled. The arbitrary coil and the arbitrary coil in the coil group in the intersecting direction are further entangled at the respective entanglement positions 22i and 21i as shown in FIG. 2C. A position 20ip is configured. In addition, each coil-shaped wire is folded back at an end portion thereof, and is locked to a coil (an outermost coil) in a direction intersecting with the coil. Configured in this way, the solid metal mesh plate 1 forms a flat plate-like outer contour having a thickness 20t corresponding to the coil diameter 20d. In the case of a coil formed on the circumference of a true cylinder, the thickness 20t is substantially the same as the coil diameter 20d. However, in the case of a coil formed on the circumference of an elliptic cylinder, Of course, the thickness is determined according to the shape of the ellipse.

本実施の形態では、図2(a)のように横方向に配列したコイル群と、図2(b)のように縦方向に配列したコイル群を、図2(c)のように両者の各絡み位置22i,21iで更に絡み合わせる(重複して絡み合わせて重複絡み位置20ipを構成している)ことにより、立体金網板1を構成している。このため、平板面に直交する方向から見ると、図4のように、略方形を成す編み目が、垂直方向/水平方向に対して略45°傾斜した構成を成す。このため、編み目が傾斜しないように構成する場合で且つ立体金網板の縦横サイズを同じに構成した立体金網板と比較して、編み目の総数が少なくなり(=編み目の総面積が広くなり)、立体金網板の向う側の視認性が向上する。なお、重複絡み位置20ipの具体的態様については、図5(a)(b)を参照されたい。   In the present embodiment, a coil group arranged in the horizontal direction as shown in FIG. 2A and a coil group arranged in the vertical direction as shown in FIG. Further entanglement is performed at each of the entanglement positions 22i and 21i (overlapping entanglement forms the overlapping entanglement position 20ip), thereby configuring the solid metal mesh plate 1. For this reason, when viewed from the direction orthogonal to the flat plate surface, as shown in FIG. 4, the stitches forming a substantially rectangular shape are inclined by approximately 45 ° with respect to the vertical / horizontal directions. For this reason, the total number of stitches is reduced (= the total area of the stitches is widened) when compared with a solid wire mesh plate in which the stitches are configured so as not to be inclined and the vertical and horizontal sizes of the solid metal mesh plates are the same. Visibility on the opposite side of the solid metal mesh plate is improved. Refer to FIGS. 5A and 5B for the specific mode of the overlapping entanglement position 20ip.

また、本実施の形態では、上述のように立体金網板1を構成している結果、先述したように「縦方向に配列されているコイル21(21a,21b)の軸芯21AX(21AXa,21AXb;図2(b)参照)が見通し孔16の軸芯に略合致される」ため、ロッド351を直接的に支持するコイルは単一のコイル(例えば、コイル21a)となる。このため、車両衝突等により立体金網板1に衝撃力が加わった場合、ロッド351に対しては単一のコイルから衝撃力が分散されて伝達されることとなり、局所的に強い衝撃力が加わることが防止される。これに対して、複数本のコイルがロッド351を直接的に支持するような構成(例えば、コイルを斜め方向に配列した場合には、上下方向の一つの見通し孔が、複数のコイルによって構成される)では、衝撃力の加わる部位によっては複数本のコイルの中の何れか少数のコイルを介して衝撃力が伝達される場合も生じ得るため、場合によってはロッド351の破壊等の恐れも生ずるが、本実施の形態では、そのような不具合は低減されている。   Further, in the present embodiment, as a result of configuring the solid metal mesh plate 1 as described above, as described above, “the axial cores 21AX (21AXa, 21AXb of the coils 21 (21a, 21b) arranged in the vertical direction”. FIG. 2 (b) is substantially matched with the axis of the line-of-sight hole 16, ”the coil that directly supports the rod 351 becomes a single coil (for example, the coil 21a). For this reason, when an impact force is applied to the solid metal mesh plate 1 due to a vehicle collision or the like, the impact force is distributed and transmitted from the single coil to the rod 351, and a strong impact force is locally applied. It is prevented. On the other hand, a configuration in which a plurality of coils directly support the rod 351 (for example, when the coils are arranged in an oblique direction, one line-of-sight hole in the vertical direction is configured by the plurality of coils. However, depending on the part where the impact force is applied, the impact force may be transmitted via any one of the plurality of coils, so that the rod 351 may be broken in some cases. However, in the present embodiment, such a problem is reduced.

上記では、車道の縁に沿って設けられ、又は、中央分離帯上に設けられる場合を述べているが、本発明はかかる場合に限定されず、例えば、船舶の甲板の縁等の防護柵として用いたり、サーキット場の防護柵として用いることも可能である。また、サーキット場等では、コイルの線材として強化ゴムを用いることにより、十分な弾力性を付与して、さらに安全性を高めるようにしてもよい。
また、上記では、ステンレス製のコイルを用いた構成例を述べているが、他の金属製のコイルは勿論、樹脂製、ゴム製、炭素繊維等の繊維強化材製、或いは、これらを組み合わせた素材製、さらには、複合材(例:金属と強化ゴムの複合材)製のコイルを用いてもよい。また、これらを立体網板内の適宜部位で組み合わせて構成してもよい。また、コイルを中空のパイプとして構成し、中に湯や加熱蒸気等を通すようにして冬季の積雪対策としてもよい。
また、上記では、編み目のサイズ/ピッチや、線材のサイズ(太さ/径)については言及していないが、必要とされる強度等に応じて、適宜の値にしてよい。また、これらの値を徐々に変化させて、視認性に適宜のグラデーションを設けてもよい。
また、上記では、立体金網板1により優れた衝撃吸収性能を達成しているが、立体金網板1の内部に衝撃吸収材を配する等して、さらに衝撃吸収性能を高めてもよい。
また、上記では、立体金網板の見通し孔に支柱の棒状材を挿通して立体金網板に係合させているが、見通し孔は、別の用途に用いることもできる。例えば、道路標識の支柱を挿通することにより、簡易に、道路標識を設置することができる。
In the above, the case where it is provided along the edge of the roadway or provided on the median strip is described, but the present invention is not limited to such a case, for example, as a protective fence such as an edge of a ship deck. It can also be used as a guard fence for circuit fields. In a circuit field or the like, sufficient elasticity may be imparted by using reinforced rubber as a coil wire, thereby further improving safety.
In the above, a configuration example using a stainless steel coil has been described. Of course, other metal coils, as well as resin, rubber, carbon fiber, or other fiber reinforcing materials, or a combination thereof are used. A coil made of a material or a composite material (eg, a composite material of metal and reinforced rubber) may be used. Moreover, you may comprise combining these in the suitable site | part in a solid net | network board. Alternatively, the coil may be configured as a hollow pipe, and hot water, heated steam, or the like may be passed therethrough as a countermeasure against snow accumulation in winter.
In the above description, the size / pitch of the stitches and the size (thickness / diameter) of the wire are not mentioned, but may be set to appropriate values depending on the required strength and the like. Also, these values may be gradually changed to provide an appropriate gradation for visibility.
Further, in the above description, excellent shock absorbing performance is achieved by the solid wire netting plate 1, but shock absorbing performance may be further improved by arranging an impact absorbing material inside the solid metal netting plate 1.
Moreover, in the above, the rod-shaped member of the support is inserted into the line-of-sight hole of the solid wire netting plate and engaged with the solid wire netting plate, but the line-of-sight hole can also be used for other purposes. For example, a road sign can be easily installed by inserting a post of a road sign.
