Description

本発明は、車道に沿って設けられ、車道を走行中の車両の積載物が衝突してきた時に受ける衝撃を吸収する衝撃吸収柵に関する。 The present invention relates to an impact absorbing fence that is provided along a roadway and absorbs an impact received when a load of a vehicle traveling on the roadway collides.

高速道路等の高架道路の側端に設置される柵として、従来、例えば特許文献１に記載の落下防止柵が知られている。この落下物防止柵は、道路の側部に設置されたガードレールと、当該ガードレールの更に外側に設置され、道路外に積載物が落下することを防止するフェンスと、を備えており、フェンスには、車両からの落下物をガードレールとの間に導くための膨出部が道路の外側に膨出するように形成されている。 Conventionally, for example, a fall prevention fence described in Patent Document 1 is known as a fence installed at a side end of an elevated road such as an expressway. The fallen object prevention fence includes a guard rail installed on the side of the road and a fence installed on the outer side of the guard rail to prevent the load from falling outside the road. The bulging part for guiding the fallen object from the vehicle to the guard rail is formed so as to bulge outside the road.

ところで、特許文献２には、防護柵に衝突した衝突時のエネルギーを吸収し、その衝撃力を柔らげる機能を備えた防護柵が開示されている。なお、この防護柵は、競輪場等の競技場に設置され、競技者が柵に衝突した際に競技者が受ける怪我の軽減を図ったものであって、道路を走行する車両の衝突を想定したものではない。 By the way, Patent Document 2 discloses a protective fence having a function of absorbing energy at the time of collision with the protective fence and softening the impact force. This protective fence is installed in a stadium such as a bicycle racetrack, and is intended to reduce injuries to the athlete when the athlete collides with the fence, and assumes the collision of a vehicle traveling on the road. It was n’t.

特開２００３−１３８５２６号公報JP 2003-138526 A 特許第３６３５０７７号公報Japanese Patent No. 3635077

特許文献１に開示された落下防止柵は、積載物を有する車両が斜めに衝突してきた場合に車両からの落下物が道路外に飛び出したり或いは道路内に跳ね返ったりするのを防止するものに過ぎず、積載物を有する車両が正面から高速で衝突してきた場合に当該車両の積載物から受ける衝撃を吸収できるものではない。このため、図３５に示すように、例えば、緊急車両や道路管理車両等の出入口また非常駐車帯など、道路１００の外側に張り出したエリアの周囲、なかでも、走行する車両が正面から衝突してくる虞の高い位置２００に設置するのには適さないものであった。特に、道路１００が跨線橋であって、上記エリアの前方に線路３００がある場合、特許文献１の落下防止柵では、積載物の衝突時の衝撃を吸収することができないために、積載物が線路３００内に放出されるのを防ぎきれず、二次災害を招来する虞があった。また、フェンスに膨出部を設ける必要がある分、構成が複雑であった。 The fall prevention fence disclosed in Patent Document 1 is only to prevent the fallen object from the vehicle from jumping out of the road or rebounding into the road when the vehicle having the load collides obliquely. In addition, when a vehicle having a load collides at high speed from the front, it cannot absorb the impact received from the load of the vehicle. For this reason, as shown in FIG. 35, for example, around an area protruding outside the road 100, such as an entrance / exit of an emergency vehicle or a road management vehicle, or an emergency parking zone, a traveling vehicle collides from the front. It was not suitable for installation at the position 200 where there is a high risk of coming. In particular, when the road 100 is an overpass and the track 300 is in front of the above area, the fall prevention fence of Patent Document 1 cannot absorb the impact when the load collides. There was a possibility that secondary discharge could be caused because it could not be prevented from being released into 300. In addition, since the bulge portion needs to be provided on the fence, the configuration is complicated.

このような課題について、特許文献２に開示された衝突時のエネルギーを吸収する防護柵を採用することが考えられるが、特許文献２の防護柵は、あくまでも競輪場等の競技場で用いられる防護柵であり、競技者が防護柵に衝突する程度のエネルギーを吸収する程度のものであるので、到底、積載物を有する車両の衝突に耐え得るものではない。また、仮に採用することができたとしても、衝突時の衝撃を吸収するためにスプリングを用いているため、構成が複雑になり、製造及び設置作業のコストが嵩むといったことが懸念される。 For such a problem, it is conceivable to employ a protective fence that absorbs energy at the time of a collision disclosed in Patent Document 2, but the protective fence of Patent Document 2 is a protection used only in a racetrack such as a bicycle race track. Since it is a fence that absorbs energy to the extent that a competitor collides with a protective fence, it cannot withstand a collision of a vehicle with a load. Even if it can be adopted, since the spring is used to absorb the impact at the time of collision, there is a concern that the configuration becomes complicated and the manufacturing and installation work costs increase.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、簡素な構造でありながらも、高速で走行している車両の積載物との衝突時における衝撃を吸収し得る衝撃吸収柵を提供することにある。 The present invention has been made in view of the above points, and an object of the present invention is to absorb an impact at the time of a collision with a load of a vehicle traveling at a high speed while having a simple structure. It is to provide a shock absorbing rail.

上記目的を達成するために、本発明は次のとおりの構成としている。 In order to achieve the above object, the present invention is configured as follows.

本発明に係る衝撃吸収柵は、車道を走行中の車両の積載物が衝突してきた時に受ける衝撃を吸収するために、前記車道に沿って設けられる衝撃吸収柵であって、前記車道に沿って立設される複数本の支柱と、これら支柱に、表面を前記車道に向けた状態で設けられた板状部材と、前記支柱と前記板状部材との間に介装され、前記支柱間において前記車道側から車道の外側に向かって延びる腕部を有する支持板と、を備え、前記支持板の後端面が、前記支柱の後面側に設けられた支持板取付片に取り付けられるとともに、前記支持板の前端面が前記板状部材の側端部に取り付けられ、前記板状部材が衝撃を受けると、前記支持板が変形して、前記板状部材が前記車道の外側に向けて移動することを特徴とする。 Shock absorbing fence according to the present invention, in order to absorb the impact received when the load of the vehicle traveling the road have collided, a shock absorbing fence provided along the roadway, along the roadway A plurality of support columns that are erected, a plate member that is provided on the support column with the surface facing the roadway, and interposed between the support column and the plate member. and a support plate having an arm portion extending outwardly of the roadway from the roadway side, the rear end surface of the support plate, together with the attached to the support plate mounting tabs provided at the rear side of said post, said support When the front end surface of the plate is attached to the side end portion of the plate-like member and the plate-like member receives an impact, the support plate is deformed, and the plate-like member moves toward the outside of the roadway. It is characterized by.

このような構成であるから、簡素な構造でありながらも、支持板が支柱間において車道側から車道の外側に向かって延びる腕部を有することによって、走行中の車両の積載物が衝突したときの衝撃を吸収することができる。また、衝撃吸収柵に車両の積載物が衝突しても、板状部材は支持板によって車道外の方向に移動可能とされているので、さらに、衝突時の衝撃を吸収することができる。 Since it is such a configuration, when the support plate has an arm portion extending from the roadway side toward the outside of the roadway between the support columns, the load of the traveling vehicle collides with the support plate. Can absorb the shock. Further, even when a vehicle load collides with the shock absorbing fence, the plate-like member can be moved in the direction outside the roadway by the support plate, so that it is possible to further absorb the shock at the time of the collision.

上記の衝撃吸収柵であって、前記板状部材は前記支柱よりも前記車道側に配置されている構成とする。 It is said shock absorption fence, Comprising: Let the said plate-shaped member be the structure arrange | positioned at the said roadway side rather than the said support | pillar .

このような構成であるから、板状部材の幅方向の長さを長く設計することができる。これにより、板状部材の面積を大きくすることができるため、板状部材によって、さらに衝撃を吸収することができる。また、板状部材がポリカーボネート等の透明材料である場合は、板状部材における透明部を広く設計することができるため、衝撃吸収柵の景観性が向上する。 Since it is such a structure, the length of the width direction of a plate-shaped member can be designed long. Thereby, since the area of a plate-shaped member can be enlarged, an impact can be further absorbed by a plate-shaped member. Moreover, since the transparent part in a plate-shaped member can be designed widely when a plate-shaped member is transparent materials, such as a polycarbonate, the landscape property of an impact-absorbing fence improves.

上記の衝撃吸収柵であって、前記支持板は、前記板状部材が衝撃を受けると、前記支持板と前記支持板取付片との間の接合部を起点として前記腕部が変形する構成とする。 The shock absorbing fence described above, wherein the support plate is configured such that when the plate-like member receives an impact, the arm portion is deformed starting from a joint portion between the support plate and the support plate mounting piece. To do.

このような構成であるから、支持板と支持板取付片との接合部を起点として確実に支持板を変形させることができるため、当該変形によって、衝突時の衝撃を確実に吸収することができる。 Since it is such a structure, since a support plate can be reliably deformed from the junction part of a support plate and a support plate attachment piece as the starting point, the impact at the time of a collision can be absorbed reliably by the said deformation | transformation. .

また、本発明に係る衝撃吸収柵は、車道を走行中の車両の積載物が衝突してきた時に受ける衝撃を吸収するために、前記車道に沿って設けられる衝撃吸収柵であって、前記車道に沿って立設される複数本の支柱と、これら支柱に、表面を前記車道に向けた状態で設けられた板状部材と、前記支柱と前記板状部材の側端部との間に介装され、前記支柱間において前記車道側から車道の外側に向かって延びる腕部を有する支持板と、前記板状部材の上端部に取り付けられ、上枠固定部材を介して間接的に前記支柱に連結される上枠と、前記板状部材の下端部に取り付けられて前記支柱のベース部に固定される下枠と、を備え、前記板状部材が衝撃を受けると、前記支持板の前記腕部と前記上枠とが変形することにより、前記板状部材が前記車道の外側に向けて移動することを特徴とする。The impact absorbing fence according to the present invention is an impact absorbing fence provided along the road to absorb an impact received when a load of a vehicle traveling on the road collides. A plurality of struts erected along the plate, a plate-like member provided on the struts with the surface facing the roadway, and a space between the strut and a side end of the plate-like member. A support plate having an arm portion extending from the roadway side toward the outside of the roadway between the support posts and an upper end portion of the plate-like member, and indirectly connected to the support posts via an upper frame fixing member An upper frame that is attached to a lower end portion of the plate-like member and fixed to a base portion of the support column, and when the plate-like member receives an impact, the arm portion of the support plate And the upper frame are deformed, so that the plate-like member is attached to the roadway. Thus being moved toward the side.

このような構成であるから、板状部材の周端部には、支持板、上枠及び下枠が取り付けられているので、板状部材の周端部を確実に覆った状態で板状部材は支柱に取り付けることができる。これにより、衝撃吸収柵が衝撃を受けても、板状部材と支柱との間に間隙が形成されることを防止することができ、衝突によって積載物が車道外に放出されることを阻止することができる。 Since it is such a structure, since the support plate, the upper frame, and the lower frame are attached to the peripheral end portion of the plate-like member, the plate-like member is securely covered with the peripheral end portion of the plate-like member. Can be attached to the column. Thereby, even if the shock absorbing fence receives an impact, it is possible to prevent a gap from being formed between the plate-like member and the support column, and to prevent the load from being released to the outside of the road due to the collision. be able to.

また、本発明に係る衝撃吸収柵は、車道を走行中の車両の積載物が衝突してきた時に受ける衝撃を吸収するために、前記車道に沿って設けられる衝撃吸収柵であって、前記車道に沿って立設される複数本の支柱と、これら支柱に、表面を前記車道に向けた状態で設けられた板状部材と、前記支柱と前記板状部材との間に介装され、前記支柱間において前記車道側から車道の外側に向かって延びる腕部を有する支持板と、を備え、前記支柱と前記支持板との取り付け箇所、及び、前記板状部材の側端部と前記支持板との取り付け箇所のいずれか一方又は両方を補強する補強部材が備えられている構成とする。 The impact absorbing fence according to the present invention is an impact absorbing fence provided along the road to absorb an impact received when a load of a vehicle traveling on the road collides. A plurality of struts erected along the plate, a plate-like member provided on the struts with the surface facing the roadway, and interposed between the strut and the plate-like member, A support plate having an arm portion extending from the roadway side toward the outside of the roadway, and a mounting position of the support column and the support plate, and a side end portion of the plate-like member and the support plate It is set as the structure provided with the reinforcement member which reinforces any one or both of the attachment location.

このような構成であるから、補強部材によって、板状部材と支持板との取り付けが補強されるため、車両の積載物が衝突により板状部材が衝撃を受けても、板状部材と支持板との支持状態を効果的に維持することができる。 Since the reinforcing member reinforces the attachment between the plate-like member and the support plate, the plate-like member and the support plate can be used even when the plate-like member receives an impact due to a collision with a vehicle load. The support state can be effectively maintained.

上記の衝撃吸収柵であって、前記補強部材は、前記支柱に沿う方向に複数に分割されている構成とする。 It is said shock absorption fence, Comprising: Let the said reinforcement member be the structure divided | segmented into plurality in the direction along the said support | pillar.

このような構成であるから、複数に分割された補強部材は、補強部材が一体である場合と比較して、曲げ応力が小さいので、補強部材が変形しづらくなる。これにより、補強部材が変形されることを防止して補強効果を高めることができる。 Since it is such a structure, since the reinforcement member divided | segmented into plurality has a small bending stress compared with the case where a reinforcement member is integral, a reinforcement member becomes difficult to deform | transform. Thereby, deformation of the reinforcing member can be prevented and the reinforcing effect can be enhanced.

上記の衝撃吸収柵であって、前記支柱と前記支持板との取り付け箇所を補強する第１補強部材が前記支柱に沿う方向に複数に分割されて設けられ、前記支持板と前記板状部材との取り付け箇所を補強する第２補強部材が前記支柱に沿う方向に複数に分割されて設けられ、第１補強部材の分割位置と、第２補強部材の分割位置と、が互いに異なる構成とする。 In the above-described shock absorbing fence, a first reinforcing member that reinforces an attachment portion between the support column and the support plate is divided into a plurality in a direction along the support column, and the support plate and the plate-like member are provided. The second reinforcing member that reinforces the attachment location is provided in a manner divided into a plurality along the column, and the dividing position of the first reinforcing member and the dividing position of the second reinforcing member are different from each other.

このような構成であるから、第１補強部材と第２補強部材とが、それぞれ異なる分割位置で分割されているので、第１補強部材の分割位置の強度が第２補強部材によって補填され、第２補強部材の分割位置の強度が第１補強部材によって補填されるため、補強効果を高めることができる。 Since it is such a structure, since the 1st reinforcement member and the 2nd reinforcement member are each divided | segmented in a different division | segmentation position, the intensity | strength of the division | segmentation position of a 1st reinforcement member is supplemented by the 2nd reinforcement member, Since the strength of the divided positions of the two reinforcing members is compensated by the first reinforcing member, the reinforcing effect can be enhanced.

本発明によれば、簡素な構造でありながらも、高速で走行している車両の積載物との衝突時における衝撃を吸収し得る衝撃吸収柵を提供できる。 ADVANTAGE OF THE INVENTION According to this invention, although it is a simple structure, the impact absorption fence which can absorb the impact at the time of the collision with the load of the vehicle which is drive | working at high speed can be provided.

The plate-like member 3 and the support plate 4 are provided (see FIG. 1).

支柱２は、少なくとも２本から構成されており、各支柱２は、車道に沿って埋め込まれた複数のアンカーを、ベース部２１の孔ｈに嵌めてナット固定することにより、車道に沿ってそれぞれ立設されている。 The struts 2 are composed of at least two, and each strut 2 is fitted along the roadway by fitting a plurality of anchors embedded along the roadway into the holes h of the base portion 21 and fixing them with nuts. It is erected.

板状部材３は、支柱２の側面のうち車道側に臨む側面に設けられており、車道を走行中の車両の積載物が衝突してきた時に受ける衝撃により、板状部材３を車道外方向に向けて変形させるように、支持板４を介して支柱２に支持されている。 The plate-like member 3 is provided on the side face of the support 2 facing the roadway side, and the plate-like member 3 is moved outwardly by the impact received when a load of a vehicle traveling on the roadway collides. It is supported by the column 2 via the support plate 4 so as to be deformed toward the surface.

支持板４は、支柱２と板状部材３との間に介装され、支柱２間において車道側から車道の外側に向かって延びる腕部４ａを有するものである。 The support plate 4 is interposed between the support column 2 and the plate-like member 3, and has an arm portion 4 a extending between the support column 2 from the roadway side toward the outside of the roadway.

また、支持板４は、支持板取付片２３を介して間接的に支柱２に取り付けられており、前記衝撃を受けることにより、支持板４と支持板取付片２３との間の接合部を起点として変形するものである。（図２参照）。 Further, the support plate 4 is indirectly attached to the support column 2 via the support plate attachment piece 23, and the joint between the support plate 4 and the support plate attachment piece 23 starts from receiving the impact. It is deformed as (See FIG. 2).

さらに、支持板４及び板状部材３は、それぞれ、支柱２よりも先に変形するように支柱２に取り付けられている。 Further, the support plate 4 and the plate-like member 3 are each attached to the support column 2 so as to be deformed before the support column 2.

さらに、板状部材３は、その上端部及び下端部が、支柱２間に設けられた上枠５及び下枠６によりそれぞれ支持されている。 Further, the upper end portion and the lower end portion of the plate-like member 3 are supported by an upper frame 5 and a lower frame 6 provided between the columns 2, respectively.

さらに、支柱２と支持板４との取り付け箇所には、２つの分割体によって構成された支持板固定補強部材７４が設けられ、支持板４と板状部材３との取り付け箇所には、３つの分割体によって構成された支持板押え部材７１が設けられている。つまり、支持板固定補強部材７４の分割位置と、支持板押え部材７１の分割位置が、互いに異なる態様で補強されている。 Further, a support plate fixing / reinforcing member 74 composed of two divided bodies is provided at the attachment location between the support column 2 and the support plate 4, and three attachment locations between the support plate 4 and the plate-like member 3 are provided. A support plate pressing member 71 constituted by a divided body is provided. That is, the dividing position of the support plate fixing reinforcing member 74 and the dividing position of the support plate pressing member 71 are reinforced in different modes.

次に、この衝撃吸収柵の組み立て方法を説明する。 Next, a method for assembling the shock absorbing fence will be described.

各支柱２に、それぞれ、支持板４を取り付ける（図７参照）。支持板４の支柱２への取り付けは、支持板取付片２３と、支持板４と、支持板固定補強部材７４と、を一体とし、各部材の孔ｈ位置を合致させた状態で、各孔ｈにボルトを差し入れてナット固定する。 A support plate 4 is attached to each column 2 (see FIG. 7). The support plate 4 is attached to the support column 2 with the support plate mounting piece 23, the support plate 4, and the support plate fixing reinforcing member 74 being integrated with each other, and the positions of the holes h of each member being matched. Insert bolts into h and fix with nuts.

支柱２を立設した後、各支柱２の下端部に、下枠６を取り付ける（図８参照）。下枠６の取り付けは、下枠取付片２４の下方から下枠６の孔ｈに向けてボルトを差し入れてナット固定する。なお、本実施形態では、下枠６と支柱２との間の補強に補強部材を取り付けていないが、補強部材を下枠６と支柱２との間に取り付けてもよい。 After the support column 2 is erected, the lower frame 6 is attached to the lower end of each support column 2 (see FIG. 8). The lower frame 6 is attached by inserting a bolt from below the lower frame attaching piece 24 toward the hole h of the lower frame 6 and fixing the nut. In the present embodiment, the reinforcing member is not attached to the reinforcement between the lower frame 6 and the column 2, but the reinforcing member may be attached between the lower frame 6 and the column 2.

下枠６を支柱２に取り付けた後、各支柱２の上端部に、上枠５を取り付ける（図５及び図９参照）。上枠本体５１上に上枠固定部材５２を載置した後に（図５参照）、上枠本体５１の後端面５１３と、上枠固定部材５２の後端面５２２とをボルト及びナット固定する。次に、上枠固定部材５２上に、上枠カバー部材５３と、上枠補強部材５４とを、この順番で載置し、各部材の孔ｈ位置を合致させた状態で、支柱２の上枠取付片２２の下方から上枠５の各部材の孔ｈに向けてボルトを差し入れて、上枠補強部材５４のＵ字状の底面でナット固定する。このとき、ボルトは上枠本体５１の切欠ＳＰを通り抜けるため、上枠本体５１と支柱２とは直接的に接続されておらず、上枠本体５１は、上枠固定部材５２を介して間接的に支柱２に取り付けられる。 After the lower frame 6 is attached to the support 2, the upper frame 5 is attached to the upper end of each support 2 (see FIGS. 5 and 9). After the upper frame fixing member 52 is placed on the upper frame main body 51 (see FIG. 5), the rear end surface 513 of the upper frame main body 51 and the rear end surface 522 of the upper frame fixing member 52 are fixed with bolts and nuts. Next, the upper frame cover member 53 and the upper frame reinforcing member 54 are placed on the upper frame fixing member 52 in this order, and the positions of the holes h of the respective members are matched with each other. Bolts are inserted from below the frame mounting pieces 22 toward the holes h of the respective members of the upper frame 5, and nuts are fixed on the U-shaped bottom surface of the upper frame reinforcing member 54. At this time, since the bolt passes through the notch SP of the upper frame main body 51, the upper frame main body 51 and the support column 2 are not directly connected, and the upper frame main body 51 is indirectly connected via the upper frame fixing member 52. Is attached to the column 2.

支柱２に、支持板４、上枠５及び下枠６をそれぞれ取り付けた後に、この支持板４、上枠５及び下枠６に板状部材３を取り付ける。 After attaching the support plate 4, the upper frame 5, and the lower frame 6 to the support 2, the plate member 3 is attached to the support plate 4, the upper frame 5, and the lower frame 6.

まず、板状部材３と上枠５との取り付けについて詳説する（図１及び図１０参照）。板状部材３の上端を、上枠カバー部材５３のカバー部５３２の溝部分に嵌入し、この状態で、板状部材３と上枠本体５１との間にパッキン（不図示）を介在させる。これとともに、板状部材３の前方に上枠押え部材７３を上枠５に沿って配置し、これらすべての部材の孔ｈを合致させた状態で、上枠押え部材７３の前方からボルトを挿通し、上枠本体５１のネジ溝ＳＧと螺合させる。これにより、板状部材３及び上枠押え部材７３が上枠５に取り付けられる。 First, the attachment of the plate-like member 3 and the upper frame 5 will be described in detail (see FIGS. 1 and 10). The upper end of the plate-like member 3 is fitted into the groove portion of the cover portion 532 of the upper frame cover member 53, and a packing (not shown) is interposed between the plate-like member 3 and the upper frame main body 51 in this state. At the same time, an upper frame pressing member 73 is disposed along the upper frame 5 in front of the plate-like member 3, and a bolt is inserted from the front of the upper frame pressing member 73 in a state where the holes h of all these members are matched. Then, it is screwed with the thread groove SG of the upper frame body 51. Thereby, the plate-like member 3 and the upper frame pressing member 73 are attached to the upper frame 5.

次に、板状部材３と下枠６との取り付けについて詳説する（図１及び図１０参照）。板状部材３と下枠６との間にパッキン（不図示）を介在させる。板状部材３の前方に下枠押え部材７２を下枠６に沿って配置し、これらすべての部材の孔ｈを合致させた状態で、下枠押え部材７２の前方からボルトを挿通し、下枠６のネジ溝ＳＧに螺合させる。これにより、板状部材３及び下枠押え部材７２が下枠６に取り付けられる。 Next, the attachment of the plate-like member 3 and the lower frame 6 will be described in detail (see FIGS. 1 and 10). A packing (not shown) is interposed between the plate-like member 3 and the lower frame 6. A lower frame presser member 72 is disposed along the lower frame 6 in front of the plate-like member 3, and bolts are inserted from the front of the lower frame presser member 72 with the holes h of all these members matched. Screwed into the thread groove SG of the frame 6. Thereby, the plate-like member 3 and the lower frame pressing member 72 are attached to the lower frame 6.

次に、板状部材３と支持板４との取り付けについて詳説する（図１及び図１０参照）。板状部材３と支持板４との間にパッキン（不図示）を介在させる。これとともに、板状部材３の前方に３つに分割された支持板押え部材７１を支持板４に沿って配置し、支持板押え部材７１と板状部材３との間に別のパッキンを介在させる。これらすべての部材の孔ｈを合致させた状態で、支持板押え部材７１の前方からボルトを挿通し、支持板４のネジ溝ＳＧに螺合させる。これにより、板状部材３及び支持板押え部材７１が支持板４に取り付けられる。 Next, attachment of the plate-like member 3 and the support plate 4 will be described in detail (see FIGS. 1 and 10). A packing (not shown) is interposed between the plate-like member 3 and the support plate 4. At the same time, a support plate pressing member 71 divided into three parts is arranged along the support plate 4 in front of the plate member 3, and another packing is interposed between the support plate pressing member 71 and the plate member 3. Let With the holes h of all these members matched, a bolt is inserted from the front of the support plate pressing member 71 and screwed into the screw groove SG of the support plate 4. As a result, the plate-like member 3 and the support plate pressing member 71 are attached to the support plate 4.

以上の組み立て方法によって、本発明に係る衝撃吸収柵１を組み立てることができる（図１及び図２参照）。 By the above assembling method, the shock absorbing fence 1 according to the present invention can be assembled (see FIGS. 1 and 2).

なお、本実施形態では、２本の支柱２を用いて１つの衝撃吸収柵１を車道に設置する例を説明したが（図１及び図２参照）、図１１に示すように、４本の支柱２を用いて３つの衝撃吸収柵１を車道に設置しても良いし、この実施形態に限らず、３本の支柱２を用いて２つの衝撃吸収柵１としても、５本以上の支柱２を用いて４つ以上の衝撃吸収柵１としてもよい。 In the present embodiment, an example in which one shock absorbing fence 1 is installed on a roadway using two support columns 2 (see FIGS. 1 and 2), as shown in FIG. Three shock absorbing fences 1 may be installed on the roadway using the pillars 2, and the present invention is not limited to this embodiment, and the two shock absorbing fences 1 using the three pillars 2 may be five or more pillars. It is good also as four or more shock absorption fences 1 using 2.

−衝撃吸収柵の作用効果−
次に、本実施形態の衝撃吸収柵に、車道を走行中の車両の積載物が衝突した際の衝撃吸収柵の作用について、図１２及び図１３を参照しながら説明する。図１２は、本発明に係る衝撃吸収柵が衝撃を受けた状態を示す斜視図、図１３は、図１２におけるＢ−Ｂ線に沿う断面図である。 -Effects of shock absorbing fence-
Next, the action of the shock absorbing fence when the load of the vehicle traveling on the roadway collides with the shock absorbing fence of the present embodiment will be described with reference to FIGS. 12 is a perspective view showing a state in which the shock absorbing fence according to the present invention receives an impact, and FIG. 13 is a sectional view taken along line BB in FIG.

本実施形態の衝撃吸収柵１に、車道を走行中の車両の積載物が衝突した場合、その衝撃の大部分は、板状部材３にかかる。板状部材３は、支柱２間において車道側から車道の外側に向って延びる腕部４ａを有する支持板４によって支持されているので、この支持板４により、板状部材３が受けた衝撃を吸収することができる。また、支持板４の腕部４ａの長さが長いほど、腕部４ａの変形量を大きくすることができるため、板状部材３が受けた衝撃を吸収する効果を高めることができる。 When a load of a vehicle traveling on a roadway collides with the shock absorbing fence 1 of the present embodiment, most of the impact is applied to the plate-like member 3. Since the plate-like member 3 is supported by the support plate 4 having the arm portion 4a extending from the roadway side toward the outside of the roadway between the columns 2, the impact received by the plate-like member 3 by the support plate 4 is supported. Can be absorbed. Moreover, since the deformation amount of the arm portion 4a can be increased as the length of the arm portion 4a of the support plate 4 is increased, the effect of absorbing the impact received by the plate-like member 3 can be enhanced.

また、板状部材３は、車道外方向に向けて変形させて衝撃を吸収することができるように支柱２に支持されているため、衝突時の衝撃をさらに吸収することができる。 Further, since the plate-like member 3 is supported by the support column 2 so as to be deformed toward the outside of the roadway and absorb the impact, the impact at the time of collision can be further absorbed.

さらに、板状部材３は、支柱２の側面のうち車道側に臨む側面に設けられているため、板状部材３は支柱２よりも車道側に配置されている。これにより、板状部材３の幅方向の長さを、各支柱２間の長さよりも長く設計することができる。つまり、板状部材３の面積を比較的大きく設計できるため、板状部材３が受ける衝撃を、さらに吸収することができる。また、板状部材３がポリカーボネート等の透明材料である場合は、板状部材３における透明部を広く設計することができるため、衝撃吸収柵１の景観性が向上する。 Furthermore, since the plate-like member 3 is provided on the side face of the support 2 facing the roadway, the plate-like member 3 is arranged on the roadway side of the support 2. Thereby, the length of the width direction of the plate-shaped member 3 can be designed longer than the length between each support | pillar 2. That is, since the area of the plate-like member 3 can be designed to be relatively large, the impact received by the plate-like member 3 can be further absorbed. Moreover, since the transparent part in the plate-shaped member 3 can be designed widely when the plate-shaped member 3 is transparent materials, such as a polycarbonate, the scenic property of the shock absorption fence 1 improves.

さらに、板状部材３の周端部には、支持板４の他に、上枠５及び下枠６が取り付けられて、板状部材３の周端部が覆われているので、衝撃吸収柵１が衝撃を受けても、板状部材３と支柱２との間に間隙が形成されることを防止することができ、衝突によって積載物が車道外に放出されることを阻止することができる。 In addition to the support plate 4, an upper frame 5 and a lower frame 6 are attached to the peripheral end portion of the plate-like member 3 so that the peripheral end portion of the plate-like member 3 is covered. Even if 1 receives an impact, it is possible to prevent a gap from being formed between the plate-like member 3 and the column 2 and to prevent the load from being released outside the roadway due to a collision. .

さらに、上枠５は、上枠本体５１と、上枠固定部材５２とから構成されており、上枠本体５１は、支柱２と直接的に接続されておらずに、上枠固定部材５２を介して間接的に支柱２に取り付けられている。つまり、この上枠本体５１及び上枠固定部材５２を介して板状部材３が支柱２に取り付けられているため、板状部材３が衝撃を受けても上枠本体５１及び上枠固定部材５２によって、板状部材３が受けた衝撃を各支柱２に伝えにくくしている。これにより、支柱２には、板状部材３が受けた衝撃がかかりにくくなるため、衝撃吸収柵１の破壊を効果的に防止することができる。 Further, the upper frame 5 includes an upper frame main body 51 and an upper frame fixing member 52, and the upper frame main body 51 is not directly connected to the support column 2, It is attached to the support | pillar 2 indirectly. That is, since the plate-like member 3 is attached to the column 2 via the upper frame main body 51 and the upper frame fixing member 52, the upper frame main body 51 and the upper frame fixing member 52 even when the plate-like member 3 receives an impact. This makes it difficult for the impact received by the plate-like member 3 to be transmitted to each column 2. Thereby, since it becomes difficult to receive the impact which the plate-shaped member 3 received to the support | pillar 2, destruction of the shock absorption fence 1 can be prevented effectively.

さらに、支持板４及び板状部材３は、それぞれ、支柱２よりも先に変形するように支柱２に取り付けられているため、衝撃吸収柵１に車両の積載物が衝突しても、支柱２の立設状態を保ったまま支持板４及び板状部材３がそれぞれ変形するので、衝突時の衝撃を吸収することができる。 Further, since the support plate 4 and the plate-like member 3 are each attached to the support column 2 so as to be deformed before the support column 2, even if the load of the vehicle collides with the shock absorbing fence 1, the support column 2. Since the support plate 4 and the plate-like member 3 are deformed while maintaining the upright standing state, it is possible to absorb the impact at the time of collision.

さらに、支持板４は、支持板取付片２３を介して支柱２に取り付けられており、前記衝撃を受けることによって支持板４と支持板取付片２３との間の接合部を起点として変形するため、当該接合部から確実に変形させて板状部材３が受けた衝撃を吸収することができる。 Further, the support plate 4 is attached to the support column 2 via the support plate attachment piece 23, and is deformed starting from the joint between the support plate 4 and the support plate attachment piece 23 by receiving the impact. The impact received by the plate-like member 3 can be absorbed by being reliably deformed from the joint.

さらに、支柱２と支持板４との取り付け位置、及び、板状部材３と支持板４との取り付け位置には、その取り付け状態を補強する補強部材（支持板押え部材７１及び支持板固定補強部材７４）が備えられているため、板状部材３と支持板４との取り付けが補強され、衝撃によっても板状部材３と支持板４との支持状態を、より効果的に維持することができる。 Further, at the mounting position of the support column 2 and the support plate 4 and the mounting position of the plate-like member 3 and the support plate 4, there are reinforcing members (support plate pressing member 71 and support plate fixing reinforcing member) that reinforce the mounting state. 74), the attachment of the plate-like member 3 and the support plate 4 is reinforced, and the support state of the plate-like member 3 and the support plate 4 can be more effectively maintained even by an impact. .

さらに、補強部材（支持板押え部材７１及び支持板固定補強部材７４）は、支柱２に沿う方向に複数に分割されているため、補強部材が一体である場合と比較して曲げ応力が小さいので、補強部材が変形しづらくなる。これにより、補強部材が変形されることを防止して補強効果を高めることができる。 Further, since the reinforcing members (the support plate pressing member 71 and the support plate fixing reinforcing member 74) are divided into a plurality in the direction along the support column 2, the bending stress is small compared to the case where the reinforcing members are integrated. The reinforcing member is difficult to deform. Thereby, deformation of the reinforcing member can be prevented and the reinforcing effect can be enhanced.

さらに、支持板押え部材７１（第１補強部材）と支持板固定補強部材７４（第２補強部材）とが、それぞれ異なる分割位置で分割されているので、支持板押え部材７１（第１補強部材）の分割位置の強度が支持板固定補強部材７４（第２補強部材）によって補填され、支持板固定補強部材７４（第２補強部材）の分割位置の強度が支持板押え部材７１（第１補強部材）によって補填されるため、補強効果を高めることができる。 Further, since the support plate pressing member 71 (first reinforcing member) and the support plate fixing reinforcing member 74 (second reinforcing member) are divided at different division positions, the supporting plate pressing member 71 (first reinforcing member) is divided. ) Is supplemented by the support plate fixing reinforcing member 74 (second reinforcing member), and the strength of the dividing position of the supporting plate fixing reinforcing member 74 (second reinforcing member) is the support plate pressing member 71 (first reinforcing member). Therefore, the reinforcing effect can be enhanced.

なお、本実施形態では、支持板押え部材７１及び支持板固定補強部材７４のみ分割体としているが、上枠押え部材７３及び下枠押え部材７２が複数の分割体によって構成されていても良い。 In the present embodiment, only the support plate pressing member 71 and the support plate fixing reinforcing member 74 are divided, but the upper frame pressing member 73 and the lower frame pressing member 72 may be configured by a plurality of divided bodies.

−支持板の変形例５−
図２１は、支持板４のさらに他の変形例を示す断面図である。本変形例では、支柱２の奥行き方向が、車道外に向けて長く設計されており、これに伴って、平面視における支持板４の腕部４ａの長さが、図２に示した形態と比較して長く設計されている。 -Modification of support plate 5-
FIG. 21 is a cross-sectional view showing still another modification of the support plate 4. In this modification, the depth direction of the support column 2 is designed to be long toward the outside of the roadway. Accordingly, the length of the arm portion 4a of the support plate 4 in plan view is the same as that shown in FIG. It is designed to be long compared.

この変形例の構成によると、平面視における支持板４の腕部４ａの長さが、図２に示した形態よりも長いため、衝突時において支持板４がさらに変形するので、当該衝撃を吸収することができる。 According to the configuration of this modified example, since the length of the arm portion 4a of the support plate 4 in plan view is longer than that shown in FIG. 2, the support plate 4 is further deformed at the time of collision, so that the shock is absorbed. can do.

Next, a modification of the upper frame in the shock absorbing fence of the present embodiment will be described with reference to FIGS. In addition, about the same component, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図２７は、上枠の変形例を示す断面図、図２８は、図２７の矢符Ｃ側からみた上枠の側面図、図２９は、上枠の他の変形例を示す断面図、図３０は、図２９の矢符Ｄ側からみた上枠の側面図、図３１は、上枠のさらに他の変形例を示す断面図、図３２は、図３１の矢符Ｅ側からみた上枠の側面図である。 27 is a cross-sectional view showing a modification of the upper frame, FIG. 28 is a side view of the upper frame viewed from the arrow C side in FIG. 27, and FIG. 29 is a cross-sectional view showing another modification of the upper frame. 30 is a side view of the upper frame as viewed from the arrow D side in FIG. 29, FIG. 31 is a cross-sectional view showing still another modification of the upper frame, and FIG. 32 is an upper frame as viewed from the arrow E side in FIG. FIG.

本変形例における上枠５は、上枠固定部材５２のみで構成されており、支柱２の上枠取付片２２は、支柱２の側面のうち、隣接する支柱２が対峙する側面の車道外側に設けられている（図２７及び図２８参照）。つまり、上枠取付片２２が、図９の実施形態と比較して、車道外側に設けられている。 The upper frame 5 in this modification is composed of only the upper frame fixing member 52, and the upper frame mounting piece 22 of the support column 2 is on the outer side of the roadway on the side surface of the support column 2 facing the adjacent support column 2. (See FIGS. 27 and 28). That is, the upper frame attaching piece 22 is provided on the outer side of the roadway as compared with the embodiment of FIG.

よって、この変形例の構成であっても、板状部材３と支柱２とを連結する上枠固定部材５２によって、板状部材３が受けた衝撃を各支柱２に伝えにくくできる。 Therefore, even in the configuration of this modified example, the upper frame fixing member 52 that connects the plate member 3 and the column 2 can hardly transmit the impact received by the plate member 3 to each column 2.

また、他の変形例として、上枠取付片２２を設けずに、支柱２の側面のうちの車道側の側面に、直接、上枠取付片２２が固定ボルトによって固定されていてもよい（図２９及び図３０参照）。 As another modification, the upper frame attachment piece 22 may be directly fixed to the side surface on the roadway side of the side surface of the support column 2 by a fixing bolt without providing the upper frame attachment piece 22 (see FIG. 29 and FIG. 30).

−下枠の変形例の説明−
次に、図３３及び図３４を参照しながら、本実施形態の衝撃吸収柵における下枠の変形例について説明する。なお、同一の構成要素については、同一符号を付してその説明を省略する。 -Description of modified examples of the lower frame-
Next, a modified example of the lower frame in the shock absorbing fence according to the present embodiment will be described with reference to FIGS. 33 and 34. In addition, about the same component, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図３３は、下枠の変形例を示す断面図、図３４は、図３３の矢符Ｆ側からみた下枠の側面図である。 33 is a cross-sectional view showing a modification of the lower frame, and FIG. 34 is a side view of the lower frame as seen from the arrow F side in FIG.

本変形例における下枠６は、下枠本体６３と下枠固定部材６４とから構成されている。また、支柱２の下枠取付片２４は、支柱２の両側面からそれぞれ突出して設けられている。 The lower frame 6 in this modified example is composed of a lower frame main body 63 and a lower frame fixing member 64. The lower frame mounting pieces 24 of the support column 2 are provided so as to protrude from both side surfaces of the support column 2.

下枠本体６３は、平板状の本体部６３１と、本体部６３１の前端から上方に突出する前端面６３２と、本体部６３１の後端から下方に突出する後端面６３３と、を備えている（図３４参照）。前端面６３２には、板状部材３をボルト固定するためのネジ溝（不図示）が幅方向（左右方向）に沿って備えられ、後端面６３３には、下枠固定部材６４をボルト固定するための孔（不図示）が幅方向（左右方向）に沿って備えられている。 The lower frame main body 63 includes a flat plate-like main body portion 631, a front end surface 632 protruding upward from the front end of the main body portion 631, and a rear end surface 633 protruding downward from the rear end of the main body portion 631 ( (See FIG. 34). The front end surface 632 is provided with a screw groove (not shown) for bolting the plate-like member 3 along the width direction (left and right direction), and the lower frame fixing member 64 is bolted to the rear end surface 633. Holes (not shown) are provided along the width direction (left-right direction).

下枠固定部材６４は、側面視逆Ｌ字状のプレートであり、支柱２とボルト固定される本体部６４１と、本体部６４１の後端から下方に突出する後端面６４２と、を備えている（図３４参照）。本体部６４１の両側端部には、それぞれ、下枠固定部材６４を各支柱２にボルト固定するための孔（不図示）が備えられている。後端面６４２には、下枠本体６３をボルト固定するための孔（不図示）が幅方向（左右方向）に沿って備えられている。 The lower frame fixing member 64 is an inverted L-shaped plate in side view, and includes a main body portion 641 fixed to the support column 2 and a bolt, and a rear end surface 642 protruding downward from the rear end of the main body portion 641. (See FIG. 34). Holes (not shown) for bolting the lower frame fixing member 64 to each support column 2 are provided at both end portions of the main body portion 641. The rear end surface 642 is provided with holes (not shown) for fixing the lower frame body 63 with bolts along the width direction (left-right direction).

これら下枠６の組み立てを説明する。下枠固定部材６４上に下枠本体６３を所定間隔開けて配置した後に、下枠本体６３の後端面６３３と下枠固定部材６４の後端面６４２とをボルト及びナットによって固定する。その後、支柱２の下枠取付片２４の上方から下枠固定部材６４に向けてボルトを差し入れてナット固定する。これにより、下枠本体６３と支柱２とが直接的に接続されておらず、下枠本体６３は、下枠固定部材６４を介して間接的に支柱２に取り付けられている。 The assembly of these lower frames 6 will be described. After the lower frame main body 63 is arranged on the lower frame fixing member 64 at a predetermined interval, the rear end surface 633 of the lower frame main body 63 and the rear end surface 642 of the lower frame fixing member 64 are fixed with bolts and nuts. Thereafter, the nut fixing pledged bolt toward the lower frame fixing member 64 from the upper side of the lower frame mounting piece 24 of the tower 2. Thereby, the lower frame main body 63 and the column 2 are not directly connected, and the lower frame main body 63 is indirectly attached to the column 2 via the lower frame fixing member 64.

この変形例の構成によると、板状部材３は、下枠本体６３及び下枠固定部材６４を介して支柱２に取り付けられているので、下枠本体６３及び下枠固定部材６４によって、板状部材３が受けた衝撃を各支柱２に伝えにくくしている。これにより、支柱２には、板状部材３が受けた衝撃がかかりにくくなるため、衝撃吸収柵１の破壊を効果的に防止することができる。 According to the configuration of this modification, the plate-like member 3 is attached to the support column 2 via the lower frame main body 63 and the lower frame fixing member 64, so that the plate-like member 3 is plate-like by the lower frame main body 63 and the lower frame fixing member 64. The impact received by the member 3 is made difficult to be transmitted to each column 2. Thereby, since it becomes difficult to receive the impact which the plate-shaped member 3 received to the support | pillar 2, destruction of the shock absorption fence 1 can be prevented effectively.

なお、今回開示した実施形態及び変形例は、すべての点で例示であって、限定的な解釈の根拠となるものではない。したがって、本発明の技術的範囲は、上記した実施形態及び変形例のみによって解釈されるものではなく、特許請求の範囲の記載に基づいて画定される。また、本発明の技術的範囲には、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。 Note that the embodiments and modifications disclosed this time are examples in all respects and do not serve as a basis for limited interpretation.
