Description

本発明は、道路の中央分離帯に設けられる防護柵に関する。   The present invention relates to a protective fence provided in a median strip of a road.

従来、道路の中央分離帯等に設けられる防護柵としては、例えば、特許文献1〜2の開示技術が提案されている。   Conventionally, for example, the disclosed technology of Patent Documents 1 and 2 has been proposed as a protective fence provided in a median strip or the like of a road.

特許文献1に開示された防護柵は、形鋼支柱の項部に取付プレートを固着し、取付プレート上に角型鋼管ビームを載置し、角型鋼管ビームの接続部にスリーブを挿入するとともにその接続部を取付プレート上に位置させ、かつ角型鋼管ビーム、スリーブ及び取付プレートにボルトを貫通してナットで緊締してあることを特徴とする。これにより、特許文献1に開示された防護柵は、表裏の違いがないため、中央分離帯の防護柵として設置することができる。   In the protective fence disclosed in Patent Document 1, a mounting plate is fixed to a neck portion of a shaped steel column, a square steel pipe beam is placed on the mounting plate, and a sleeve is inserted into a connecting portion of the square steel pipe beam. The connecting portion is located on the mounting plate, and the square steel pipe beam, the sleeve and the mounting plate are penetrated with bolts and tightened with nuts. As a result, the protective fence disclosed in Patent Document 1 can be installed as a protective fence for the median strip because there is no difference between the front and back sides.

しかし、特許文献1に開示された防護柵は、角型鋼管ビーム、スリーブ及び取付プレートにボルトを貫通してナットで緊締してあることにより、災害や事故等の緊急時には、中央分離帯に車両が通行可能な区間を形成することができないという問題があった。   However, since the protective fence disclosed in Patent Document 1 penetrates the square steel pipe beam, the sleeve, and the mounting plate with bolts and is tightened with nuts, the vehicle is installed in the median strip in an emergency such as a disaster or accident. However, there was a problem that it was not possible to form a section where traffic could pass.

特許文献2に開示された中央分離帯用防護柵は、移動側防護柵を固定側防護柵に着脱自在に連結する連結部を備えている。移動側防護柵は、前記道路の上を移動可能な少なくとも1つの台車部を備える。連結部は、固定側および移動側ビームパイプ間を連結するビームパイプ挿入部材と、当該ビームパイプ挿入部材を移動させる操作部とを備えている。固定側および移動側のビームパイプの端部には、スリットが形成されている。操作部の突出部分は、スリットを通して、当該ビームパイプの外部に突出している。これにより、特許文献2に開示された中央分離帯用防護柵は、災害や事故等の緊急時には、中央分離帯に車両が通行可能な区間を形成することが可能となる。   The protective fence for the median strip disclosed in Patent Document 2 includes a connecting portion that detachably connects the movable protective fence to the fixed protective fence. The moving-side guard fence includes at least one cart that can move on the road. The connecting portion includes a beam pipe inserting member that connects the fixed side and moving side beam pipes, and an operation unit that moves the beam pipe inserting member. Slits are formed at the ends of the fixed and movable beam pipes. The projecting portion of the operation portion projects through the slit to the outside of the beam pipe. Accordingly, the guard fence for the median strip disclosed in Patent Document 2 can form a section through which the vehicle can pass in the median strip in an emergency such as a disaster or an accident.

しかし、特許文献2に開示された中央分離帯用防護柵は、台車部等が設けられることによって、その設置に必要とする幅の広い構成であり、狭小な領域しかない中央分離帯には設置することができないという問題点があった。また、特許文献2に開示された中央分離帯用防護柵は、ボルトとナットの締結を解除してから、ビームパイプ端部のスリット間について、ビームパイプ挿入部材の操作部を移動させることで、ビームパイプの連結を解除する構成であるため、解除に手間がかかり緊急時の対応に時間がかかるという問題点があった。   However, the guard fence for the median strip disclosed in Patent Document 2 has a wide structure required for its installation due to the provision of the trolley and the like, and is installed in the median strip having only a narrow area. There was a problem that I could not do it. In addition, in the protective fence for the median strip disclosed in Patent Document 2, after the fastening of the bolt and the nut is released, the operation portion of the beam pipe insertion member is moved between the slits of the end portion of the beam pipe, Since the configuration is such that the connection of the beam pipe is released, there is a problem in that it takes time to release the beam pipe and it takes time to deal with an emergency.

The support column 20 is provided with bolt holes 22a at two positions on the upper end side of the web 22.

支柱20は、図3に示すように、ウェブ22に、鋼板を側面から見てL字状に折り曲げられて形成されるブラケット28が当接されている。このブラケット28は、ウェブ22に当接される面にボルト孔28aが2か所に形成され、後述するビーム材30に当接される面にボルト孔28bが1か所に形成される。この支柱20は、ウェブ22のボルト孔22aと、ブラケット28のボルト孔28aとに、ボルト61の軸を貫通させて、ボルト61の先端にナット62を螺着させることで、ブラケット28がボルト接合されている。   As shown in FIG. 3, the support column 20 is in contact with a web 22 with a bracket 28 formed by bending a steel plate into an L shape when viewed from the side. In this bracket 28, bolt holes 28a are formed at two locations on the surface that contacts the web 22, and bolt holes 28b are formed at one location on the surface that contacts the beam material 30 described below.

支柱20は、中央分離帯の地中に埋設された角型鋼管からなる鞘管29に挿通されて、鞘管29の内面に鋼棒24が近接されるものとなる。これにより、支柱20は、中央分離帯に設置されたとき、ガタツキを抑制することが可能となる。また、支柱20は、載置板23が鞘管29の上端に載置されることで、地面に立設されている。これにより、隣接する支柱20は、載置板23よりも上方のウェブ22の突出高さを揃えることが可能となる。このため、隣接するビーム材30の高さを揃えることが可能となり、連結部材40の取り付けも容易となる。   The column 20 is inserted into a sheath pipe 29 made of a square steel pipe buried in the ground of the median strip, and the steel rod 24 is brought close to the inner surface of the sheath pipe 29. As a result, the column 20 can suppress rattling when installed in the median strip. The support column 20 is erected on the ground by mounting the mounting plate 23 on the upper end of the sheath tube 29. As a result, the adjacent columns 20 can have the same protruding height of the web 22 above the mounting plate 23. Therefore, the heights of the adjacent beam members 30 can be made uniform, and the connection member 40 can be easily attached.

By being screwed on, the bracket 28 is bolted.

図6(a)は、本発明の第1実施形態に係る防護柵1における連結部材40を示す斜視図であり、図6(b)は、その側面図である。   FIG. 6A is a perspective view showing the connecting member 40 in the protective fence 1 according to the first embodiment of the present invention, and FIG. 6B is a side view thereof.

連結部材40は、鋼板の両端が折り曲げられて、道路幅方向Yに沿った鉛直断面形状がコの字状に形成され、下側が開放されている。連結部材40は、道路幅方向Yに向けて間隔をあけて設けられてそれぞれ連結孔42が形成される一対の連結側板41と、一対の連結側板41の上端に連結される連結面板43とを有する。連結側板41は、長手方向が道路延伸方向Xに向けて延長されており、長手方向の両端付近に、連結孔42が形成される。   The connecting member 40 is formed by bending both ends of a steel plate so that the vertical cross-sectional shape along the road width direction Y is U-shaped, and the lower side is open. The connection member 40 includes a pair of connection side plates 41 that are provided at intervals in the road width direction Y and each have a connection hole 42 formed therein, and a connection face plate 43 that is connected to the upper ends of the pair of connection side plates 41.

連結孔42は、図6(b)に示すように、道路延伸方向Xに向けて延長される横孔部42aと、横孔部42aに対して垂直方向の下方に向けて延長される縦孔部42bとで構成され、道路延伸方向Xに沿った鉛直断面形状がL字状に形成される。横孔部42aの道路延伸方向Xにおける延長寸法は、縦孔部42bの上下方向Zにおける延長寸法よりも長くなるように形成される。縦孔部42bは、横孔部42aにおいて、連結部材40の中央に近い側の端部に配置されている。   As shown in FIG. 6B, the connecting hole 42 includes a lateral hole portion 42a extending in the road extending direction X and a vertical hole extending downward in the vertical direction with respect to the lateral hole portion 42a. The vertical cross section along the road extending direction X is formed in an L shape. The extension dimension of the lateral hole portion 42a in the road extending direction X is formed to be longer than the extension dimension of the vertical hole portion 42b in the vertical direction Z. The vertical hole portion 42b is arranged at the end of the horizontal hole portion 42a on the side closer to the center of the connecting member 40.

連結部材40は、図2に示すように、ビーム材30の上方から被せられて、ビーム材30の外側に配置されるものとなる。連結部材40は、図3に示すように、一対のビーム側板31に一対の連結側板41が当接されて、近接配置される。また、連結部材40は、上側のビーム面板33に連結面板43が当接されて、近接配置されるものとなる。連結側板41は、一対のビーム側板31に当接された場合にビーム孔32に対応する位置に連結孔42が設けられるものとなる。連結孔42は、ビーム孔32に対して大きさを異ならせて形成されて、本実施形態においては、ビーム孔32よりも小さく形成されているものとしているが、ビーム孔32よりも大きく形成されるものであってもよい。また、本実施形態においては、連結側板41がビーム側板31に当接されて、近接配置されるものを例示したが、本発明における連結側板は、ビーム孔に対応する位置に連結孔が設けられていればよく、ビーム側板31に離間されて、近接配置されていてもよい。   As shown in FIG. 2, the connecting member 40 covers the beam member 30 from above and is arranged outside the beam member 30. As shown in FIG. 3, the connecting member 40 is disposed in proximity to the pair of beam side plates 31 with the pair of connecting side plates 41 contacting each other. Further, the connecting member 40 is arranged in proximity to the upper beam face plate 33 with the connecting face plate 43 abutting on it. The connection side plate 41 is provided with the connection hole 42 at a position corresponding to the beam hole 32 when abutted against the pair of beam side plates 31.

It may be one. Further, in the present embodiment, the connection side plate 41 is in contact with the beam side plate 31 and is arranged in the vicinity, but the connection side plate in the present invention is provided with the connection hole at a position corresponding to the beam hole. The beam side plate 31 may be spaced apart from the beam side plate 31 and may be disposed in close proximity thereto.

なお、図7(a)は、本発明の第1実施形態に係る防護柵1における連結孔42の変形例を示す側面図であり、図7(b)は、連結孔42の他の変形例を示す側面図である。   7A is a side view showing a modification of the connecting hole 42 in the protective fence 1 according to the first embodiment of the present invention, and FIG. 7B is another modification of the connecting hole 42. It is a side view which shows.

連結孔42は、図7(a)に示すように、道路延伸方向Xに向けて延長される横孔部42aと、横孔部42aに対して垂直方向の下方に向けて延長される縦孔部42bとで構成され、道路延伸方向Xに沿った鉛直断面形状がL字状に形成される。この縦孔部42bは、横孔部42aにおいて、連結部材40の長手方向の端部に近い側に配置されている。横孔部42aの道路延伸方向Xにおける延長寸法は、縦孔部42bの上下方向Zにおける延長寸法よりも長くなるように形成される。なお、かかる場合には、連結側板41が一対のビーム側板31に近接配置された場合に、ビーム孔32に対応する位置に連結孔42が設けられるものとなる。即ち、ビーム孔32が、道路延伸方向Xに沿った鉛直断面形状がL字状に形成されるものとなる。   As shown in FIG. 7A, the connecting hole 42 includes a lateral hole portion 42a extending in the road extending direction X and a vertical hole extending downward in the vertical direction with respect to the lateral hole portion 42a. The vertical cross section along the road extending direction X is formed in an L shape. The vertical hole 42b is arranged on the side of the horizontal hole 42a closer to the end of the connecting member 40 in the longitudinal direction. The extension dimension of the lateral hole portion 42a in the road extending direction X is formed to be longer than the extension dimension of the vertical hole portion 42b in the vertical direction Z. In such a case, when the connecting side plate 41 is arranged close to the pair of beam side plates 31, the connecting hole 42 is provided at a position corresponding to the beam hole 32. That is, the beam hole 32 is formed so that the vertical cross-sectional shape along the road extending direction X is L-shaped.

また、連結孔42は、図7(b)に示すように、道路延伸方向Xに向けて延長される横孔部42aと、横孔部42aの中央部付近から垂直方向の下方に向けて延長される縦孔部42bとで構成され、道路延伸方向Xに沿った鉛直断面形状がT字状に形成されてもよい。横孔部42aの道路延伸方向Xにおける延長寸法は、縦孔部42bの上下方向Zにおける延長寸法よりも長くなるように形成される。なお、かかる場合にも、連結側板41が一対のビーム側板31に近接配置された場合に、ビーム孔32に対応する位置に連結孔42が設けられるものとなる。即ち、ビーム孔32が、道路延伸方向Xに沿った鉛直断面形状がT字状に形成されるものとなる。   As shown in FIG. 7B, the connecting hole 42 extends laterally in the road extending direction X, and extends downward from the vicinity of the center of the lateral hole 42a in the vertical direction. The vertical cross-sectional shape along the road extending direction X may be formed in a T shape. The extension dimension of the lateral hole portion 42a in the road extending direction X is formed to be longer than the extension dimension of the vertical hole portion 42b in the vertical direction Z. Even in such a case, when the connecting side plate 41 is arranged close to the pair of beam side plates 31, the connecting hole 42 is provided at a position corresponding to the beam hole 32. That is, the beam hole 32 is formed such that the vertical cross-sectional shape along the road extending direction X is T-shaped.

貫通部材50は、図3に示すように、断面円形状の鋼棒からなり、一対のビーム側板31及び一対の連結側板41に貫通される。換言すれば、貫通部材50は、道路幅方向Yを貫通方向として、ビーム材30及び連結部材40に貫通させる。また貫通部材50は、両端部がそれぞれ同一方向に向けて折り曲げられて形成される一対の係止部51が形成されている。   As shown in FIG. 3, the penetrating member 50 is made of a steel rod having a circular cross section and penetrates the pair of beam side plates 31 and the pair of connecting side plates 41. In other words, the penetrating member 50 penetrates the beam member 30 and the connecting member 40 with the road width direction Y as the penetrating direction. Further, the penetrating member 50 has a pair of locking portions 51 formed by bending both ends in the same direction.

図8は、本発明の第1実施形態に係る防護柵1における貫通部材50を、ビーム材30と連結部材40とに貫通させる状態を示す斜視図である。   FIG. 8 is a perspective view showing a state where the penetrating member 50 in the protective fence 1 according to the first embodiment of the present invention is penetrated through the beam member 30 and the connecting member 40.

防護柵1は、連結部材40が道路幅方向Yに沿った鉛直断面形状がコの字状に形成されることによって、上方からビーム材30に容易に載置することが可能となる。防護柵1は、連結部材40が、ビーム材30の外側に設けられることによって、ビーム孔32と連結孔42との位置を容易に整合することが可能となる。   The protective fence 1 can be easily placed on the beam member 30 from above because the connecting member 40 is formed in a U-shaped vertical cross-sectional shape along the road width direction Y. Since the connecting member 40 is provided outside the beam member 30, the protective fence 1 can easily align the positions of the beam hole 32 and the connecting hole 42.

防護柵1は、ビーム孔32に対応する位置に設けられた連結孔42に、貫通部材50を図中矢印M方向(道路幅方向Y)を貫通方向として、貫通されるものとなる。   The protective fence 1 is penetrated through the connecting hole 42 provided at the position corresponding to the beam hole 32, with the penetrating member 50 as the penetrating direction in the arrow M direction (road width direction Y) in the drawing.

このとき、防護柵1は、係止部51の延長寸法が、横孔部32aの道路延伸方向Xにおける延長寸法及び横孔部42aの道路延伸方向Xにおける延長寸法よりも短く形成される。これにより、貫通部材50を貫通方向(道路幅方向Y)に向けて、横孔部32a、42aから貫通させることが可能となる。   At this time, the protective fence 1 is formed such that the extension dimension of the locking portion 51 is shorter than the extension dimension of the lateral hole portion 32a in the road extension direction X and the extension dimension of the lateral hole portion 42a in the road extension direction X. This allows the penetrating member 50 to pass through the lateral holes 32a and 42a in the penetrating direction (road width direction Y).

図9(a)は、本発明の第1実施形態に係る防護柵1において、ビーム材30と連結部材40とに貫通させた貫通部材50を貫通方向を回転軸として回転させる状態を示す側面図であり、図9(b)は、その道路幅方向Yに沿った鉛直断面図である。   FIG. 9A is a side view showing a state in which the penetrating member 50 penetrating the beam member 30 and the connecting member 40 is rotated about the penetrating direction as a rotation axis in the protective fence 1 according to the first embodiment of the present invention. 9 (b) is a vertical cross-sectional view taken along the road width direction Y.

防護柵1は、図9(a)に示すように、横孔部32a、42aから貫通させた貫通部材50を、貫通方向(道路幅方向Y)を回転軸として図中矢印R方向に向けて回転させる。   As shown in FIG. 9A, the protective fence 1 has a penetrating member 50 penetrating from the lateral holes 32a and 42a in a direction of an arrow R in the drawing with the penetrating direction (road width direction Y) as a rotation axis. Rotate.

このとき、防護柵1は、図9(b)に示すように、係止部51の延長寸法が、縦孔部32bにおける上下方向の延長寸法及び縦孔部42bの上下方向の延長寸法よりも長く形成される。これにより、防護柵1は、貫通部材50が縦孔部32b、42bにおいて貫通方向(道路幅方向Y)に向けて引き抜かれるのを防止することが可能となる。   At this time, in the protective fence 1, as shown in FIG. 9B, the extension dimension of the locking portion 51 is larger than the extension dimension of the vertical hole portion 32b in the vertical direction and the extension dimension of the vertical hole portion 42b in the vertical direction. Formed long. Accordingly, the protective fence 1 can prevent the penetrating member 50 from being pulled out in the penetrating direction (road width direction Y) at the vertical hole portions 32b and 42b.

なお、防護柵1は、図9(a)に示すように、連結孔42が、ビーム孔32と大きさを異ならせて形成されることによって、隣接するビーム材30の間隔に施工誤差が生じた場合であっても、その誤差を吸収することが可能となり、貫通部材50をビーム孔32及び連結孔42に貫通させることが可能となる。   As shown in FIG. 9A, in the protective fence 1, the connecting hole 42 is formed with a size different from that of the beam hole 32, so that a construction error occurs in the interval between the adjacent beam members 30. Even in the case, the error can be absorbed, and the penetrating member 50 can penetrate the beam hole 32 and the connecting hole 42.

図10は、本発明の第1実施形態に係る防護柵1において、ビーム材30と連結部材40とに貫通させた貫通部材50を上下方向Zに向けて移動させる状態を示す側面図である。   FIG. 10 is a side view showing a state in which the penetrating member 50 penetrating the beam member 30 and the connecting member 40 is moved in the vertical direction Z in the protective fence 1 according to the first embodiment of the present invention.

防護柵1は、図10に示すように、縦孔部32b、42bが、下方に向けて延長されていることによって、貫通部材50が図中矢印P方向(上下方向Z)に向けて移動可能に構成されて、縦孔部32b、42bに貫通されるものとなる。このとき、防護柵1は、係止部51が重力の作用を受けて下方に向けて延長されることとなり、連結部材40に係止される。   In the protective fence 1, as shown in FIG. 10, the vertical holes 32b and 42b are extended downward, so that the penetrating member 50 can move in the direction of arrow P (up and down direction Z) in the figure. The vertical holes 32b and 42b are penetrated. At this time, the protective fence 1 is extended downward by the engagement portion 51 under the action of gravity, and is engaged with the connecting member 40.

このように、防護柵1は、貫通部材50を貫通方向(道路幅方向Y)に向けてビーム材30と連結部材40とに貫通させ、貫通方向を回転軸として回転させ、さらに下方(上下方向Z)に向けて移動させることによって、隣接するビーム材30が連結部材40に連結されるものとなる。   In this way, the protective fence 1 penetrates the beam member 30 and the connecting member 40 in the penetrating direction (road width direction Y) in the penetrating member 50 and rotates the beam member 30 and the connecting member 40 with the penetrating direction as a rotation axis and further downward (vertical direction By moving the beam member 30 toward Z), the adjacent beam members 30 are connected to the connecting member 40.

また、防護柵1は、連結部材40をビーム材30から取り外すには、上述した手順とは逆の手順で、貫通部材50を動作させる。即ち、防護柵1は、貫通部材50を縦孔部32b、42b内で上方に移動させた状態で、係止部51の延長方向を、横孔部32a、42aの延長方向に揃えるように回転させ、横孔部32a、42aから引き抜かれる。これにより、防護柵1は、連結部材40をビーム材30から容易に取り外すことが可能となる。   In addition, in order to remove the connecting member 40 from the beam member 30, the protective fence 1 operates the penetrating member 50 in a procedure reverse to the above-described procedure. That is, the protective fence 1 rotates so that the extension direction of the locking portion 51 is aligned with the extension direction of the horizontal holes 32a, 42a in a state where the penetrating member 50 is moved upward in the vertical holes 32b, 42b. Then, the horizontal holes 32a and 42a are pulled out. As a result, the protective fence 1 can easily remove the connecting member 40 from the beam member 30.

上述したような、貫通部材50の動作は、人の手で行わることにより、容易に行うことが可能となる。従って、防護柵1は、貫通部材50をビーム材30及び連結部材40に貫通させることによって、工具を用いることなく、隣接するビーム材30の連結及び解除を容易に行うことが可能となる。また、防護柵1は、貫通部材50が、それぞれ同一方向に向けて折り曲げられて形成された係止部51を有することによって、貫通部材50を横孔部32a、42aに貫通させるのを容易なものとしながら、縦孔部32b、42bに配置されたときに、貫通方向に向けて引き抜かれるのを防止することが可能となる。   The operation of the penetrating member 50 as described above can be easily performed by performing it manually. Therefore, in the protective fence 1, by penetrating the penetrating member 50 into the beam member 30 and the connecting member 40, it is possible to easily connect and disconnect the adjacent beam members 30 without using a tool. Further, the protective fence 1 has the engaging portions 51 formed by bending the penetrating members 50 in the same direction, so that the penetrating member 50 can be easily penetrated through the lateral holes 32a and 42a. However, when arranged in the vertical holes 32b and 42b, it is possible to prevent the pull-out in the penetrating direction.

また、この防護柵1は、ビーム材30と連結部材40との連結を解除するための手順を踏まなければ、その連結を解除することができないものとなる。即ち、防護柵1は、車両等に衝突された場合、上述したような連結解除手順で貫通部材50が動作されることはほとんど起こりえない。このため、防護柵1は、車両等に衝突された場合であっても、ビーム材30が連結部材40に連結された状態を保つことが可能となる。その結果、防護柵1は、車両等に衝突されたときに防護柵として用いられる部材(連結部材40や貫通部材50等)が道路上に飛散するのを防止する機能を発揮することが可能となる。   In addition, the protective fence 1 cannot be released unless the procedure for releasing the connection between the beam member 30 and the connecting member 40 is performed. That is, when the protective fence 1 is collided with a vehicle or the like, it is almost impossible for the penetrating member 50 to be operated in the above-described disconnection procedure. Therefore, the protective fence 1 can keep the beam member 30 connected to the connecting member 40 even when the protective fence 1 is collided with a vehicle or the like. As a result, the protective fence 1 can exhibit the function of preventing the members (the connecting member 40, the penetrating member 50, etc.) used as the protective fence from being scattered on the road when the vehicle is collided. Become.

図11(a)は、本発明の第1実施形態に係る防護柵1において、連結部材40がビーム材30から取り外された状態を示す側面図であり、図11(b)は、ビーム材30が中央分離帯から取り外された状態を示す側面図である。   FIG. 11A is a side view showing a state in which the connecting member 40 is removed from the beam member 30 in the protective fence 1 according to the first embodiment of the present invention, and FIG. 11B is a beam member 30. FIG. 4 is a side view showing a state in which is removed from the median strip.

防護柵1は、図11(a)に示すように、連結部材40がビーム材30から取り外されて、ビーム材30がブラケット28を介して支柱20に支持されたものとなる。そして、防護柵1は、図11(b)に示すように、地中に設けられる鞘管29に挿入される支柱20を引き抜くことによって、ビーム材30を支柱20及びブラケット28に一体化された状態で、図中矢印Q方向に向けて、中央分離帯から取り外すことが可能となる。   As shown in FIG. 11A, the protective fence 1 is such that the connecting member 40 is removed from the beam member 30 and the beam member 30 is supported by the column 20 via the bracket 28. Then, in the protective fence 1, as shown in FIG. 11B, the beam member 30 is integrated with the support column 20 and the bracket 28 by pulling out the support column 20 inserted into the sheath pipe 29 provided in the ground. In this state, it can be removed from the central separator in the direction of arrow Q in the figure.

防護柵1は、図1に示すように、区間Sが、ビーム材30の道路延伸方向Xにおける延長寸法をL1とする区間S1と、ビーム材30の道路延伸方向Xにおける延長寸法をL2とする区間S2とを有し、中央分離帯に設置される。   As shown in FIG. 1, the protective fence 1 has a section S1 in which a section S1 has an extension dimension L1 in the road extension direction X of the beam 30 and an extension dimension L2 in the road extension direction X of the beam material 30. It has a section S2 and is installed in the median strip.

図12は、区間S1に設置された本発明の第1実施形態に係る防護柵1が、中央分離帯から取り外された状態を示す側面図であり、図13は、その平面図である。   FIG. 12 is a side view showing a state in which the protective fence 1 according to the first embodiment of the present invention installed in the section S1 is removed from the median strip, and FIG. 13 is a plan view thereof.

防護柵1は、区間S1に設けられるビーム材30の延長L1を、例えば、1.0m程度に設定することによって、工具を用いることなく、連結部材40をビーム材30から人力で取り外し可能なものとしながら、支柱20と一体化された状態でビーム材30を人力で中央分離帯から取り外すことが可能となる。防護柵1は、区間S1に設けられるビーム材30を、図1に示すように、例えば、5本連結させることによって、この区間S1が5.0m程度に開放可能に構成されるものとなる。その結果、防護柵1は、図13に示すように、事故や災害等の緊急時に早急に反対車線に向けて車両を誘導することが可能となる。   The guard fence 1 is one in which the connecting member 40 can be manually detached from the beam member 30 without using a tool by setting the extension L1 of the beam member 30 provided in the section S1 to about 1.0 m, for example. However, the beam member 30 can be manually removed from the median strip while being integrated with the support column 20. As shown in FIG. 1, the guard fence 1 is configured such that, for example, by connecting five beam members 30 provided in the section S1, the section S1 can be opened to about 5.0 m. As a result, the protective fence 1 can promptly guide the vehicle toward the opposite lane in an emergency such as an accident or a disaster as shown in FIG.

また、防護柵1は、区間S2に設けられるビーム材30の延長L2を、例えば、2.0m程度と、L1より長く設定することによって、工具を用いることなく、連結部材40をビーム材30から人力で取り外し可能なものとしながら、クレーン等の楊重機械を用いて、支柱20と一体化された状態でビーム材30を中央分離帯から取り外すことが可能となる。このように、区間Sが、例えば、20m程度に設定されることによって、物資等を運搬するトレーラー等の大型車両を反対車線に向けて転回させることも可能となる。   Further, in the protective fence 1, by setting the extension L2 of the beam member 30 provided in the section S2 to be longer than L1 such as about 2.0 m, the connecting member 40 can be removed from the beam member 30 without using a tool. It is possible to remove the beam member 30 from the median strip in a state of being integrated with the support column 20 by using a toothed machine such as a crane while making it removable by human power. Thus, by setting the section S to, for example, about 20 m, it becomes possible to turn a large vehicle such as a trailer that transports goods and the like toward the opposite lane.

なお、防護柵1は、例えば、既存の技術のような台車等を用いることなく、図12及び図13に示すように、ビーム材30と、連結部材40とを順次道路延伸方向Xに向けて延伸させて、中央分離帯に着脱自在に設置されるものとなる。防護柵1は、その設置に際し、中央分離帯を道路幅方向Yに向けて幅広く構成される必要はなく、狭小な領域の中央分離帯に設置することが可能なものとなる。   In addition, the guard fence 1 is configured such that the beam member 30 and the connecting member 40 are sequentially directed in the road extension direction X as shown in FIGS. It will be stretched and removably installed in the median strip. When the guard fence 1 is installed, the median strip does not need to be wide in the width direction Y of the road, and can be installed in the median strip in a narrow area.

このように、防護柵1は、道路幅方向Yにおける中央分離帯の幅が狭小であっても、支柱20を鞘管29に挿通、引き抜きを行うことによって、中央分離帯に容易に設置、取り外しを行うことが可能となる。また、防護柵1は、道路延伸方向Xを中心として、正面側と背面側とで対称に構成されるものとなる。このため、防護柵1は、正面側、又は背面側の何れか側から車両に衝突された場合であっても、車線から外れて防護柵に衝突した車両を元の車線に誘導することが可能となり、中央分離帯の防護柵として機能するものとなる。   Thus, even if the width of the median strip in the road width direction Y is narrow, the protective fence 1 can be easily installed and removed from the median strip by inserting the column 20 into the sheath pipe 29 and pulling it out. It becomes possible to do. Further, the protective fence 1 is configured so that the front side and the back side are symmetrical about the road extending direction X. Therefore, even if the protective fence 1 collides with the vehicle from either the front side or the rear side, it is possible to guide the vehicle that has left the lane and collided with the protective fence to the original lane. And will function as a protective fence for the median strip.

連結部材140は、鋼板で構成され、道路幅方向Yに沿った鉛直断面形状が矩形状に形成され、一対の連結側板141と、一対の連結側板141の上端に連結される上側の連結面板143と、一対の連結側板141の下端に連結される下側の連結面板144とを有する。   The connecting member 140 is made of a steel plate, has a rectangular vertical cross-section along the road width direction Y, and has a pair of connecting side plates 141 and an upper connecting face plate 143 connected to the upper ends of the pair of connecting side plates 141. And a lower connecting face plate 144 connected to the lower ends of the pair of connecting side plates 141.

連結側板141は、長手方向が道路延伸方向Xに向けて延長されており、連結側板141の長手方向の両端付近に、連結孔142を有する。   The connecting side plate 141 has a longitudinal direction extending in the road extending direction X, and has connecting holes 142 near both ends in the longitudinal direction of the connecting side plate 141.

連結孔142は、道路延伸方向Xに向けて延長される横孔部142aと、横孔部142aに対して垂直方向の下方に向けて延長される縦孔部142bとで構成され、道路延伸方向Xに沿った鉛直断面形状がL字状に形成される。横孔部142aの道路延伸方向Xにおける延長寸法は、縦孔部142bの上下方向Zにおける延長寸法よりも長くなるように形成される。縦孔部142bは、横孔部142aにおいて、連結部材140の中央に近い側に配置されている。   The connecting hole 142 includes a lateral hole portion 142a extending in the road extending direction X and a vertical hole portion 142b extending downward in the vertical direction with respect to the lateral hole portion 142a. The vertical cross-sectional shape along X is formed in an L shape. The extension dimension of the lateral hole portion 142a in the road extending direction X is formed to be longer than the extension dimension of the vertical hole portion 142b in the vertical direction Z. The vertical hole portion 142b is arranged near the center of the connecting member 140 in the horizontal hole portion 142a.

防護柵1は、断面矩形状に形成された連結部材140の内部にビーム材30が挿通される、即ち、連結部材140がビーム材30の外側に配置されるものとなる。これにより、防護柵1は、ビーム孔32と、連結孔142とを整合させるのを容易に行うことが可能となる。また、これにより、防護柵1は、車両等に衝突されたとき、連結部材140がビーム材30から飛散するのを防止する効果をより発揮することが可能となる。   In the protective fence 1, the beam member 30 is inserted into the inside of the connecting member 140 having a rectangular cross section, that is, the connecting member 140 is arranged outside the beam member 30. As a result, the protective fence 1 can easily align the beam hole 32 and the connecting hole 142. Further, as a result, the protective fence 1 can further exert the effect of preventing the connecting member 140 from scattering from the beam member 30 when the vehicle is hit by a vehicle or the like.

このとき、防護柵1は、連結部材140がビーム材30の外側面に当接されて、近接配置されるものとなる。防護柵1は、連結部材140を図中矢印T方向に向けて移動させることで、ビーム孔32に対応する位置に連結孔142が設けられるものとなる。かかる場合においても、本発明を適用した防護柵1は、上述した作用効果を奏するものとなる。   At this time, the protective fence 1 is arranged in close proximity with the connecting member 140 abutting on the outer surface of the beam member 30. In the protective fence 1, the connecting hole 142 is provided at a position corresponding to the beam hole 32 by moving the connecting member 140 in the direction of arrow T in the figure.

防護柵1は、断面矩形状に形成された連結部材140がビーム材30の内側に挿通され、連結部材140がビーム材30の内側に配置されるものとなる。これにより、防護柵1は、車両等に衝突されたとき、連結部材140がビーム材30から飛散するのを防止する効果をより発揮することが可能となる。   In the protective fence 1, a connecting member 140 having a rectangular cross section is inserted inside the beam member 30, and the connecting member 140 is arranged inside the beam member 30. As a result, the protective fence 1 can more effectively exhibit the effect of preventing the connecting member 140 from scattering from the beam material 30 when the vehicle is collided with.

このとき、防護柵1は、連結部材140をビーム材30の内側面に当接されて、近接配置されるものとなる。防護柵1は、連結部材140を図中矢印T方向に向けて移動させることで、ビーム孔32に対応する位置に連結孔142が設けられるものとなる。かかる場合においても、本発明を適用した防護柵1は、上述した作用効果を奏するものとなる。   At this time, the protective fence 1 is arranged in close proximity with the connecting member 140 abutting on the inner surface of the beam member 30. In the protective fence 1, the connecting hole 142 is provided at a position corresponding to the beam hole 32 by moving the connecting member 140 in the direction of arrow T in the figure.

図19(a)は、本発明の第2実施形態に係る防護柵10における連結部材240を示す斜視図であり、図19(b)は、その平面図である。   FIG. 19 (a) is a perspective view showing the connecting member 240 in the protective fence 10 according to the second embodiment of the present invention, and FIG. 19 (b) is a plan view thereof.

連結部材240は、鋼板からなり、鋼板の両端が折り曲げられて、道路幅方向Yに沿った鉛直断面形状がコの字状に形成され、下側が開放されている。   The connecting member 240 is made of a steel plate, and both ends of the steel plate are bent so that the vertical cross-sectional shape along the road width direction Y is formed in a U shape, and the lower side is opened.

連結部材240は、面内方向が上下方向Zに延長される一対の連結側板241と、一対の連結側板241の上端が連結される連結面板243とを有する。   The connecting member 240 includes a pair of connecting side plates 241 whose in-plane directions extend in the vertical direction Z, and a connecting face plate 243 to which the upper ends of the pair of connecting side plates 241 are connected.

図20は、本発明の第2実施形態に係る防護柵10における、貫通部材250をビーム材230と連結部材240とに貫通される状態を示す道路延伸方向Xに沿った鉛直断面図である。   FIG. 20 is a vertical cross-sectional view taken along the road extending direction X showing a state in which the penetrating member 250 is penetrated by the beam member 230 and the connecting member 240 in the protective fence 10 according to the second embodiment of the present invention.

防護柵10は、上側のビーム面板233に、連結面板243が当接され、ビーム孔233bに対応する位置に連結孔243bが設けられるものとなる。また、防護柵10は、上側のビーム面板233における受け孔233cに対応する位置に、連結部材240における受け孔243cが設けられるものとなる。   In the protective fence 10, the connection face plate 243 is brought into contact with the upper beam face plate 233, and the connection hole 243b is provided at a position corresponding to the beam hole 233b. Further, in the protective fence 10, a receiving hole 243c in the connecting member 240 is provided at a position corresponding to the receiving hole 233c in the upper beam face plate 233.

防護柵10は、位置を整合されたビーム孔233bと、連結孔243bとに、貫通部材250の係止部252を貫通させ、図中矢印K方向に回転させ、下側のビーム面板234のビーム孔234bまで貫通させる。このように、防護柵10は、貫通部材250が上下方向Zを貫通方向として、ビーム材230と連結部材240とに貫通されるものとなる。   The protective fence 10 penetrates the locking portion 252 of the penetrating member 250 through the beam hole 233b and the connecting hole 243b whose positions are aligned, and rotates in the direction of arrow K in the figure, so that the beam of the lower beam face plate 234 is formed. It penetrates to the hole 234b. As described above, in the protective fence 10, the penetrating member 250 is penetrated by the beam member 230 and the connecting member 240 with the vertical direction Z as the penetrating direction.

このとき、防護柵10は、下端側の係止部252の延長寸法が、下側のビーム孔234bの道路延伸方向Xにおける延長寸法よりも短く形成されることによって、貫通部材250を貫通方向(道路幅方向Y)に向けて、ビーム材230と連結部材240とに貫通することが可能となる。   At this time, in the protective fence 10, the extension dimension of the lower end side locking portion 252 is formed to be shorter than the extension dimension of the lower beam hole 234b in the road extension direction X, so that the penetration direction of the penetrating member 250 ( The beam member 230 and the connecting member 240 can be penetrated in the road width direction Y).

図21(a)は、本発明の第2実施形態に係る防護柵10における、貫通部材250を貫通方向を回転軸として回転される状態を示す斜視図であり、図21(b)は、その道路延伸方向Xに沿った鉛直断面図である。   21A is a perspective view showing a state in which the penetrating member 250 is rotated about the penetrating direction as a rotation axis in the protective fence 10 according to the second embodiment of the present invention, and FIG. It is a vertical cross-sectional view along the road extension direction X.

防護柵10は、ビーム孔233b、連結孔243bから貫通させた貫通部材250を、貫通方向(上下方向Z)を回転軸として図中矢印W方向に向けて回転させる。   The protective fence 10 rotates the penetrating member 250 penetrating from the beam hole 233b and the connecting hole 243b in the arrow W direction in the drawing with the penetrating direction (vertical direction Z) as the rotation axis.

なお、防護柵10は、図21(b)に示すように、上端側の係止部251の延長寸法が、上側のビーム孔233bにおける道路延伸方向Xの延長寸法及び連結孔243bの道路延伸方向Xの延長寸法よりも長く形成されることによって、上端側の係止部251が上側のビーム面板233に係止されるものとなる。その結果、防護柵10は、貫通部材250を貫通方向(上下方向Z)に向けて下方に落下されるのを防止することが可能となる。   As shown in FIG. 21B, in the protective fence 10, the extension dimension of the locking portion 251 on the upper end side is the extension dimension of the road extension direction X in the upper beam hole 233b and the road extension direction of the connection hole 243b. By being formed longer than the extension dimension of X, the upper end side locking portion 251 is locked to the upper beam face plate 233. As a result, the protective fence 10 can prevent the penetrating member 250 from dropping downward in the penetrating direction (vertical direction Z).

図22は、本発明の第2実施形態に係る防護柵10において、ビーム材230と連結部材240とに貫通された貫通部材250を上下方向Zに向けて移動させた状態を示す道路延伸方向Xに沿った鉛直断面図である。   FIG. 22 is a road extension direction X showing a state in which the penetrating member 250 penetrated by the beam member 230 and the connecting member 240 is moved in the vertical direction Z in the protective fence 10 according to the second embodiment of the present invention. It is a vertical cross-sectional view along.

防護柵10は、図22に示すように、貫通部材250が図中矢印P方向(上下方向Z)に向けて移動可能に構成されて、突起部251aが受け孔233c、243cに挿通されるものとなる。   As shown in FIG. 22, in the protective fence 10, the penetrating member 250 is configured to be movable in the direction of arrow P (up and down direction Z) in the figure, and the protrusion 251a is inserted into the receiving holes 233c and 243c. Becomes

このように、防護柵10は、貫通部材250を貫通方向(上下方向Z)に向けてビーム材230と連結部材240とに貫通させ、貫通方向を回転軸として回転させ、さらに下方(上下方向Z)に向けて移動させることによって、隣接するビーム材230が連結部材240に連結されるものとなる。   In this manner, the protective fence 10 penetrates the beam member 230 and the connecting member 240 in the penetrating direction (vertical direction Z) through the penetrating member 250 and rotates the beam member 230 and the connecting member 240 around the rotating direction, and further downward (vertical direction Z). ), The adjacent beam members 230 are connected to the connecting member 240.

また、防護柵10は、上述した手順とは逆に、即ち、貫通部材250を図中矢印P方向の上方に移動させた状態で、係止部252の延長方向とビーム孔234bの延長方向とを揃えるように回転させ、さらに上方に向けて引き抜かれることによって、隣接するビーム材230の連結を容易に解除する、換言すれば、連結部材240を容易に取り外すことが可能となる。   Further, the protective fence 10 is reversed from the above procedure, that is, in the state where the penetrating member 250 is moved upward in the direction of arrow P in the figure, the extension direction of the locking portion 252 and the extension direction of the beam hole 234b are changed. The beam members 230 adjacent to each other can be easily released from each other by rotating them so that they are aligned with each other, and by pulling them upward, in other words, the connecting member 240 can be easily removed.

上述したような、貫通部材250の動作は、人の手で行われることにより、容易に行うことが可能となる。従って、防護柵10は、貫通部材250をビーム材230及び連結部材240に貫通させることによって、工具を用いることなく、連結部材240をビーム材30に容易に設置及びその取り外しを行うことが可能となる。   The operation of the penetrating member 250 as described above can be easily performed by being manually performed. Therefore, the protective fence 10 can easily install and remove the connecting member 240 on the beam member 30 without using a tool by penetrating the penetrating member 250 through the beam member 230 and the connecting member 240.

また、この防護柵10は、連結部材240の取り外し手順を踏まなければ、その連結を解除することができないものとなる。即ち、防護柵10は、車両等に衝突された場合、上述したような手順通りに、貫通部材50が動作することはほとんど起こりえない。このため、防護柵1は、車両等に衝突された場合であっても、ビーム材230が連結部材240に連結された状態を保つことが可能となる。その結果、防護柵1は、車両等に衝突されたとき、連結部材240や貫通部材250が道路上に飛散することなく、中央分離帯に設けられる防護柵としての機能を発揮することが可能となる。   Further, the protection fence 10 cannot be disconnected unless the connection member 240 is removed. That is, when the protective fence 10 is collided with a vehicle or the like, the penetrating member 50 is unlikely to operate according to the procedure described above. Therefore, the protective fence 1 can keep the beam member 230 connected to the connecting member 240 even when the protective fence 1 is collided with a vehicle or the like. As a result, the protective fence 1 can function as a protective fence provided in the median strip without the connecting member 240 and the penetrating member 250 being scattered on the road when the vehicle is hit by a vehicle or the like. Become.

また、防護柵10は、道路を車両等が通行した場合には、振動等の作用を受けて貫通部材250が上下方向Zを回転軸として回転しようするものの、突起部251aが受け孔233c、243cに挿通されていることにより、その回転を防止することが可能となる。   Further, in the protective fence 10, when a vehicle or the like passes through a road, the penetrating member 250 attempts to rotate about the vertical direction Z as a rotation axis due to the action of vibration or the like, but the projecting portions 251a have the receiving holes 233c and 243c. It is possible to prevent the rotation by being inserted into.

また、防護柵10は、受け孔233c、243cに突起部251aが挿通されるとき、下側のビーム面板234の下方に、下端側の係止部252が配置されるものとなる。これにより、防護柵10は、図中矢印P方向(上下方向Z)の上方に向けて、貫通部材250を移動させたとしても、下端側の係止部252が、下側のビーム面板234に係止されるため、貫通部材250がビーム材230及び連結部材240から引き抜かれるのを防止することが可能となる。   Further, in the protective fence 10, when the projecting portion 251a is inserted into the receiving holes 233c and 243c, the lower end side locking portion 252 is arranged below the lower beam face plate 234. As a result, in the protective fence 10, even if the penetrating member 250 is moved upward in the direction of the arrow P (upward and downward direction Z) in the figure, the locking portion 252 on the lower end side is attached to the lower beam face plate 234. Since it is locked, it is possible to prevent the penetrating member 250 from being pulled out from the beam member 230 and the connecting member 240.

図23(a)は、本発明の第2実施形態における防護柵10の変形例を示す道路延伸方向Xに沿った鉛直断面図であり、図23(b)は、その道路幅方向Yに沿った断面図である。   FIG. 23 (a) is a vertical cross-sectional view taken along the road extending direction X showing a modified example of the protective fence 10 according to the second embodiment of the present invention, and FIG. 23 (b) is taken along the road width direction Y. FIG.

貫通部材260は、断面円形状の鋼棒からなり、一対のビーム面板233、234及び連結面板243に貫通される、即ち、上下方向Zを貫通方向として貫通されるものである。貫通部材260は、上端部が上側のビーム面板233に係止される上端側の係止部261と、下端部が折り曲げられて形成される下端側の係止部262とを有し、ビーム孔233b、234b及び連結孔243bに貫通されている。なお、当該連結孔243bは、係止部261よりも径小とされていればよく、例えば、円形状に構成されるものとする。   The penetrating member 260 is made of a steel rod having a circular cross section, and penetrates the pair of beam face plates 233, 234 and the connecting face plate 243, that is, the vertical direction Z is the penetrating direction. The penetrating member 260 has an upper end side locking portion 261 whose upper end portion is locked to the upper beam face plate 233, and a lower end side locking portion 262 which is formed by bending the lower end portion. 233b, 234b and the connecting hole 243b are penetrated. The connecting hole 243b may have a diameter smaller than that of the locking portion 261, and is configured, for example, in a circular shape.

下側に配置されるビーム面板234は、下面に貫通部材260が上下方向Zを回転軸として回転された場合に係止部262が係止される突出片269を有する。   The beam face plate 234 arranged on the lower side has a protruding piece 269 on the lower surface, with which the locking portion 262 is locked when the penetrating member 260 is rotated about the vertical direction Z as a rotation axis.

突出片269は、U字状に形成されて、一方の先端が道路幅方向Yに向けて傾斜して形成される一端部269aを有し、他方の先端がビーム面板234に取付けられるものとなる。このように、一端部269aが切り欠かれていることによって、係止部262を上側のビーム孔233bから下側のビーム孔234bに貫通させたとき、貫通部材260が貫通方向(上下方向Z)を回転軸として回転されるものとなる。そして、突出片269の溝部に、係止部262が載置されるものとなる。   The protruding piece 269 is formed in a U shape, and has one end 269a formed with one end inclined toward the road width direction Y, and the other end attached to the beam face plate 234. . Since the one end portion 269a is cut out in this manner, when the locking portion 262 is penetrated from the upper beam hole 233b to the lower beam hole 234b, the penetrating member 260 is in the penetrating direction (vertical direction Z). Will be rotated about. Then, the locking portion 262 is placed in the groove portion of the protruding piece 269.

かかる場合において、連結部材240をビーム材230から取り外すには、貫通部材260を上方に向けて移動させた状態で、係止部262の延長方向と、ビーム孔234bの延長方向とを揃えるように、貫通方向(上下方向Z)を回転軸として回転させ、係止部262を上方に向けて引き抜かれることにより行われる。   In this case, in order to remove the connecting member 240 from the beam member 230, the extension direction of the locking portion 262 and the extension direction of the beam hole 234b are aligned with the penetrating member 260 moved upward. , And the engaging portion 262 is pulled out upward by rotating the penetrating direction (vertical direction Z) around the rotation axis.

かかる場合においても、上述した作用効果、即ち、工具を用いることなく、連結部材240をビーム材230に容易に設置及びその取り外しを行うことが可能となる作用効果を奏するものとなる。   Even in such a case, the above-described operation and effect, that is, the operation and effect in which the connecting member 240 can be easily installed in and removed from the beam member 230 without using a tool, can be obtained.

また、かかる場合において、道路を車両等が通行した場合、振動等の作用を受けて貫通部材260が上下方向Zを回転軸として回転しようするものの、下側の係止部262が突出片269に係止されるものとなり、その回転を防止することが可能となる。   Further, in this case, when a vehicle or the like passes through the road, the penetrating member 260 attempts to rotate about the vertical direction Z as a rotation axis due to the action of vibration or the like, but the lower engaging portion 262 is attached to the protruding piece 269. It becomes locked and it is possible to prevent its rotation.

また、かかる場合において、図23(b)に示すように、ビーム孔233b、234bに下側の係止部262が挿通されるとき、下側のビーム面板234の下方に、下端側の係止部262が配置される。これにより、上下方向Zの上方に向けて、貫通部材260を移動させたとしても、下端側の係止部262が、下側のビーム面板234に係止されるため、貫通部材260がビーム材230及び連結部材240から引き抜かれるのを防止することが可能となる。   Further, in such a case, as shown in FIG. 23B, when the lower locking portion 262 is inserted into the beam holes 233b and 234b, the lower locking portion is locked below the lower beam face plate 234. The part 262 is arranged. As a result, even if the penetrating member 260 is moved upward in the up-down direction Z, the lower end side locking portion 262 is locked to the lower beam face plate 234, so that the penetrating member 260 can be used. It is possible to prevent it from being pulled out from 230 and the connecting member 240.
