Description

この発明は、車両用防護柵として代表的なガードレールの技術分野に属し、さらにいえば、緊急時（非常時）の中央分離帯に車両通行できる開口部を形成することが可能なガードレールの連結構造体の技術分野に属する。 The present invention belongs to the technical field of a guardrail typical as a guardrail for a vehicle, and more specifically, a guardrail connecting structure capable of forming an opening through which a vehicle can pass in a median strip in an emergency (emergency). It belongs to the technical field of the body.

車両用防護柵として代表的なガードレールは、確実な車両誘導性、良好な視線誘導性の役割を果たすべく、通常、適度な剛性と靱性を備えた波型ビームと称されるビーム材を隙間なく一連に連結して実施される。 A guardrail, which is a typical guardrail for vehicles, has a beam material called a corrugated beam, which usually has appropriate rigidity and toughness, without gaps in order to play a role of reliable vehicle guidance and good line-of-sight guidance. It is carried out by connecting in a series.

しかし、中央分離帯に設置されるガードレールは、事故等の緊急時に緊急車両が中央分離帯を越えて反対車線へ行き来できる開口部（例えば、５００ｍ毎に４０ｍ程度）を実現可能な構造を要求されるので、当該開口部（開放部）を形成する区間（例えば、前記４０ｍ程度）に設置するガードレールは、前記ビーム材を隙間なく一連に連結して実施することは困難であった。
すなわち、前記開口部に、可動と固定に切り換え可能なガードレール（可動ガードレール）を複数設置することになるが、緊急時の移動作業（開口作業）は、迅速かつ効率良く行うため、各々の可動ガードレールを互いに連結しない構成で（例えば、特許文献１の図１８、図１９のサイドカバー３０ｃを参照）、１０ｃｍ程度の間隔をあけて断続的に設置して実施していた。
加えて、緊急時の移動作業（開口作業）は基本、人力で行うことを前提としているため、１基あたりの可動ガードレールは、取り扱い性等を考慮し、通常の固定ガードレールよりも短スパン（コンパクト）化して実施していた。
よって、中央分離帯の開口部に設置される複数の可動ガードレールは、前記ビーム材を隙間なく一連に連結して実施することは困難であり、短スパン化したビーム材を断続的に設置する構成で実施しているが故に、確実な車両誘導性、良好な視線誘導性の役割を果たしているとは云えず、解決すべき課題となっている。 However, the guardrail installed in the median strip is required to have a structure capable of realizing an opening (for example, about 40 m every 500 m) that allows an emergency vehicle to cross the median strip and move to the opposite lane in an emergency such as an accident. Therefore, it is difficult to carry out a guardrail installed in a section (for example, about 40 m) forming the opening (open portion) by connecting the beam materials in a series without a gap.
That is, a plurality of guardrails (movable guardrails) that can be switched between movable and fixed are installed in the opening, but each movable guardrail is used for quick and efficient movement work (opening work) in an emergency. (For example, refer to the side covers 30c of FIGS. 18 and 19 of Patent Document 1), and the side covers 30c were intermittently installed at intervals of about 10 cm.
In addition, since it is assumed that the movement work (opening work) in an emergency is basically performed manually, the movable guardrail per unit has a shorter span (compact) than the normal fixed guardrail in consideration of handleability etc. ) Was implemented.
Therefore, it is difficult to connect the beam materials in a series without gaps to the plurality of movable guardrails installed in the opening of the median strip, and the beam materials with shortened spans are intermittently installed. Since it is carried out in Japan, it cannot be said that it plays a role of reliable vehicle guidance and good line-of-sight guidance, and it is a problem to be solved.

ところで、特許文献２には、中央分離帯の開口部に、隙間なく一連に連結することを可能とする移動側ビームパイプを備えた中央分離帯用防護柵（ガードパイプ）が開示されてはいるが、ガードレールに関する技術については未だ開発されていないのが現状である。 By the way, Patent Document 2 discloses a guard pipe for a median strip provided with a moving side beam pipe that can be connected in a series without a gap at the opening of the median strip. However, the current situation is that the technology related to guardrails has not yet been developed.

次に、本発明に係るガードレールの連結構造体およびガードレール連結用のスライドビームユニットの実施例を図面に基づいて説明する。 Next, an example of the guardrail connecting structure and the slide beam unit for connecting the guardrail according to the present invention will be described with reference to the drawings.

（ガードレールの連結構造体の全体構成についての説明）
本発明に係るガードレールの連結構造体は、図１Ａ、Ｂに示すように、固定ガードレール２０、２０同士の間の一定区間Ｓに（１つ又は）複数の可動ガードレール１０が一連に配置され、隣接するガードレール２０、１０（又は１０、１０）のビーム材２１、１１（又は１１、１１）同士の間にスライドビームユニット１が跨設されてなる。 (Explanation of the overall configuration of the guardrail connection structure)
In the guardrail connecting structure according to the present invention, as shown in FIGS. 1A and 1B, (one or) a plurality of movable guardrails 10 are arranged in a series in a fixed section S between the fixed guardrails 20 and 20 and adjacent to each other. The slide beam unit 1 is straddled between the beam members 21, 11 (or 11, 11) of the guardrails 20, 10 (or 10, 10).

本発明は、図１Ｂが分かりやすいように、主として中央分離帯用のガードレールに適用される。ただし、本発明に係るスライドビームユニット１は、隣接するガードレールのビーム材同士の連結に用いられるので、路側用のガードレールにも適用可能である。 The present invention is mainly applied to guardrails for medians so that FIG. 1B is easy to understand. However, since the slide beam unit 1 according to the present invention is used for connecting the beam materials of adjacent guardrails, it can also be applied to a roadside guardrail.

前記固定ガードレール２０は、従来から使用されているものをそのまま利用できる。言い換えると、本発明は、従来から使用されている固定ガードレール全般に適用可能である。ちなみに、図１、図３に係る固定ガードレール２０は、一例として、道路延長方向に所定の間隔をあけて地面にモルタル２４等で立設（固設）される支柱部２２と、各支柱部２２を間に挟むように固定されるビーム取付部材２３と、道路延長方向に沿って設けられるビーム材２１とをボルト接合手段等によって一体的に組み立てて構成されている。 As the fixed guardrail 20, those conventionally used can be used as they are. In other words, the present invention is applicable to all conventional fixed guardrails. Incidentally, the fixed guardrail 20 according to FIGS. 1 and 3 includes, as an example, a support column 22 that is erected (fixed) on the ground with a mortar 24 or the like at a predetermined interval in the road extension direction, and each support column 22. The beam mounting member 23, which is fixed so as to sandwich the two, and the beam material 21 provided along the road extension direction are integrally assembled by a bolt joining means or the like.

前記可動ガードレール１０もまた、従来から使用されているものをそのまま利用できる。一般的に、可動ガードレールは、図１に示したようなキャスター付きの可動ガードレール１０と、図９、図１０に示したようなキャスター無しの可動ガードレール１０’とに大別されるが、本発明は、これらの可動ガードレール１０、１０’全般に適用可能である。要するに、本発明が適用可能な可動ガードレールは、所定のビーム材を備えた移動可能な構成であればよく、種々のバリエーションが存在する。
ちなみに、図１に係る可動ガードレール１０は、台車部１２と、前記台車部１２から立ち上がる第１の支柱部１３と、第２の支柱部１４と、前記第１と第２の支柱部１３、１４に取り付けられるビーム材１１と、前記第２の支柱部１４に内嵌され、地面に埋設された外管１６内に挿入可能な内管１５とからなり、前記内管１５の抜き差し操作により可動又は固定のガードレールに切り換え可能な構成で実施されている（図２〜図５も参照）。ただし、従来、可動ガードレールの端部に設けられていたサイドカバー３０ｃ（上記特許文献１の図１８、図１９参照）に相当する部材は使わない。 As for the movable guardrail 10, the one that has been conventionally used can be used as it is. Generally, the movable guardrail is roughly classified into a movable guardrail 10 with casters as shown in FIG. 1 and a movable guardrail 10'without casters as shown in FIGS. 9 and 10. Is applicable to all of these movable guardrails 10, 10'. In short, the movable guardrail to which the present invention can be applied may have a movable configuration provided with a predetermined beam material, and there are various variations.
Incidentally, the movable guardrail 10 according to FIG. 1 includes a bogie portion 12, a first strut portion 13 rising from the bogie portion 12, a second strut portion 14, and the first and second strut portions 13, 14 The beam material 11 to be attached to the inner pipe 15 and the inner pipe 15 which is fitted into the second support column 14 and can be inserted into the outer pipe 16 embedded in the ground, and can be moved or moved by the insertion / removal operation of the inner pipe 15. It is implemented in a configuration that can be switched to a fixed guardrail (see also FIGS. 2 to 5). However, conventionally, a member corresponding to the side cover 30c (see FIGS. 18 and 19 of Patent Document 1 above) provided at the end of the movable guardrail is not used.

前記一定区間Ｓは、通常時は、前記可動ガードレール１０の連結構造体が防護柵の役割を果たし、緊急時（非常時）は、前記連結構造体が移動（撤去）され、車両通行可能な開口部が形成される。具体的に、前記一定区間Ｓは、４０ｍ程度の長さに設定されているものが多く、通常時は、１基あたり２．５ｍ〜３．０ｍスパンのビーム材１１（１１’）を備えた可動ガードレール１０（１０’）を、道路延長方向に沿って１４基程度設けている。ちなみに、図１では、すべてキャスター付きの可動ガードレール１０で実施しているが、図９に示すように、キャスター無しの可動ガードレール１０’との混合体で実施することも勿論できるし、すべてをキャスター無しの可動ガードレール１０’で実施することも勿論できる。 In the fixed section S, the connecting structure of the movable guardrail 10 normally serves as a guard fence, and in an emergency (emergency), the connecting structure is moved (removed) to allow vehicles to pass through. The part is formed. Specifically, the fixed section S is often set to a length of about 40 m, and normally, each unit is provided with a beam material 11 (11') having a span of 2.5 m to 3.0 m. About 14 movable guardrails 10 (10') are provided along the road extension direction. By the way, in FIG. 1, all are carried out with the movable guardrail 10 with casters, but as shown in FIG. 9, of course, it can be carried out with a mixture with the movable guardrail 10'without casters, and all are carried out with casters. Of course, it can also be carried out with a movable guardrail 10'without it.

（本発明に係るスライドビームユニットについての説明）
前記スライドビームユニット１は、図６Ａ、Ｂ等に示したように、スライドビーム部材２とロックピン部材３とからなる。
前記スライドビーム部材２は、スライドビーム本体２ａに、前記隣接するガードレール２０、１０（又は１０、１０）のビーム材２１、１１（又は１１、１１）の上部と下部にそれぞれ掛け留め可能な掛け留め部材２ｂと、前記ビーム材２１、１１（又は１１、１１）の既設孔１９（図７、図８参照）と芯が一致する貫通孔２ｃとを備え、前記ビーム材２１、１１（又は１１、１１）に沿ってスライド可能な構成とされる。
そして、図８Ａ〜図８Ｃに段階的に示したように、前記隣接するガードレール２０、１０（又は１０、１０）のビーム材２１、１１（又は１１、１１）に前記スライドビーム部材２が略均等に跨った状態で、芯が一致した前記既設孔１９及び貫通孔２ｃに、前記ロックピン部材３が差し込まれることで当該隣接するガードレール同士２０、１０（又は１０、１０）が連結されている。 (Explanation of Slide Beam Unit According to the Present Invention)
As shown in FIGS. 6A, 6B, etc., the slide beam unit 1 includes a slide beam member 2 and a lock pin member 3.
The slide beam member 2 can be fastened to the slide beam main body 2a on the upper and lower portions of the beam members 21, 11 (or 11, 11) of the adjacent guardrails 20, 10 (or 10, 10), respectively. The beam material 21, 11 (or 11, 11) is provided with a member 2b and a through hole 2c whose core coincides with the existing hole 19 (see FIGS. 7 and 8) of the beam material 21, 11 (or 11, 11). It is configured to be slidable along 11).
Then, as shown stepwise in FIGS. 8A to 8C, the slide beam member 2 is substantially equal to the beam members 21, 11 (or 11, 11) of the adjacent guardrails 20, 10 (or 10, 10). By inserting the lock pin member 3 into the existing holes 19 and through holes 2c having the same cores, the adjacent guardrails 20, 10 (or 10, 10) are connected to each other.

本実施例に係る前記スライドビーム本体２ａは、金属製であり、図７が分かりやすいように、適用対象であるビーム材１１（２１）の外面形状に沿って屈曲するように、より具体的には前記ビーム材１１（２１）の断面形状と略一致する波型断面に形成されている。ちなみに本実施例に係るスライドビーム本体２ａは、一例として、縦寸３５０ｍｍ、横寸７００ｍｍ、波高７５ｍｍで実施されている。
なお、前記ビーム材１１（２１）の形態には種々のバリエーションがあるが、そのほとんどが２山ビーム、３山ビームと称される波型ビームであり、本発明（に係る前記スライドビーム本体２ａ）はこれら波型ビームを含むビーム材のすべてに適用可能である。 The slide beam main body 2a according to the present embodiment is made of metal, and more specifically so as to bend along the outer surface shape of the beam material 11 (21) to be applied so that FIG. 7 can be easily understood. Is formed in a corrugated cross section that substantially matches the cross-sectional shape of the beam material 11 (21). Incidentally, the slide beam main body 2a according to this embodiment is implemented as an example with a vertical dimension of 350 mm, a horizontal dimension of 700 mm, and a wave height of 75 mm.
There are various variations in the form of the beam material 11 (21), but most of them are wave-shaped beams called two-mountain beam and three-mountain beam, and the slide beam main body 2a according to the present invention (related to the present invention). ) Is applicable to all beam materials including these wavy beams.

本実施例に係る前記掛け止め部材２ｂも金属製であり、所定の幅寸（例えば、３２０ｍｍ）を有する断面フック状に形成され、前記スライドビーム本体２ａの内側面における上部の左右に２か所、及び下部の左右に２か所の計４つ、溶接等の接合手段で設けられている。
前記掛け止め部材２ｂは、前記スライドビーム本体２ａが前記ビーム材１１（２１）に沿って良好に安定状態でスライドできるように掛け止めることができれば、どのような形態であってもよい。例えば、本実施例では、前記貫通孔２ｃと芯が一致する部位に同形状の貫通孔を形成して実施しているが、前記掛け止め部材２ｂよりも狭い幅寸で、前記貫通孔を避けた位置に所定の間隔をあけて設けることも勿論可能である。
前記掛け留め部材２ｂを前記スライドビーム本体２ａの内側面に設けた意義は、掛け留め部材２ｂとスライドビーム本体２ａとの継ぎ目を外部に晒さないで、安全性及び良好な視線誘導性をより高めるためである。
