The mounting plate 41 is installed on the support column 20 by appropriate fixing means such as screwing, adhesion, welding, and fitting. That is, the base 40 is installed so as to protrude inward in the column 20.

また、基部４０における支柱２０の内側方向に位置する端部には、上下角度調整機構を構成する基部側第１嵌合部４２が形成される。当該基部側第１嵌合部４２は、例えば、テーパを有した凹状の第１受け部からなり、略中心部には連結部材５０を固定するためのネジ孔４３が前後方向に設けられる。また、基部４０は、支柱２０の取付孔２２から挿通される固定ボルトＢ３による取付作業が行い易いよう、当該取付孔２２に対応する位置にて固定される。 Moreover, the base side 1st fitting part 42 which comprises an up-down angle adjustment mechanism is formed in the edge part located in the inner side direction of the support | pillar 20 in the base 40. FIG. The base-side first fitting portion 42 is, for example, a concave first receiving portion having a taper, and a screw hole 43 for fixing the connecting member 50 is provided in the front-rear direction at a substantially central portion. Further, the base 40 is fixed at a position corresponding to the mounting hole 22 so that the mounting work by the fixing bolt B3 inserted through the mounting hole 22 of the column 20 can be easily performed.

また、連結部材５０は、図４に示すように、ビーム３０に挿通される軸部５１と、軸部５１の一端に設けられる連結部５２とからなる。当該連結部５２は、上下角度調整機構を構成する基部側第２嵌合部５３と、前後角度調整機構とを備えてなる。 As shown in FIG. 4, the connecting member 50 includes a shaft portion 51 inserted through the beam 30 and a connecting portion 52 provided at one end of the shaft portion 51. The connection portion 52 includes a base-side second fitting portion 53 that constitutes a vertical angle adjustment mechanism, and a front-rear angle adjustment mechanism.

軸部５１は、ビーム３０の挿通孔３１に挿通し得るよう、例えば、略棒状に形成されており、一端に連結部５２が設けられるとともに、他端にネジ孔５４が設けられる。当該連結部５２は、例えば、図３に示すように、軸部５１の軸線に対して一方側へ突出し、基部側第１嵌合部４２に対応する基部側第２嵌合部５３を有してなり、連結部５２の略中央部には、軸部５１の軸線に対して直交する前後方向に貫通孔５５が形成される。当該基部側第２嵌合部５３は、例えば、略球面状に突出して形成される第１当接部とされ、第１受け部に対して摺動自在となるよう構成される。 The shaft portion 51 is formed, for example, in a substantially rod shape so that the shaft portion 51 can be inserted into the insertion hole 31 of the beam 30, and is provided with a connecting portion 52 at one end and a screw hole 54 at the other end. For example, as shown in FIG. 3, the connecting portion 52 protrudes to one side with respect to the axis of the shaft portion 51 and has a base-side second fitting portion 53 corresponding to the base-side first fitting portion 42. Thus, a through hole 55 is formed in a substantially central portion of the connecting portion 52 in the front-rear direction perpendicular to the axis of the shaft portion 51. The base side second fitting portion 53 is, for example, a first abutting portion formed so as to protrude in a substantially spherical shape, and is configured to be slidable with respect to the first receiving portion.

更に、連結部５２の基部側第２嵌合部５３と対向する箇所には、前後角度調整機構を構成する押さえ部側第１嵌合部５６が設けられる。当該押さえ部側第１嵌合部５６は、例えば、略球面状を有した凹状の第２受け部からなる。また、押さえ部側第１嵌合部５６に対応する押さえ部側第２嵌合部５８を有する押さえ部５７が設けられる。当該押さえ部側第２嵌合部５８は、例えば、略半球面状に形成される第２当接部とされ、第２受け部に対して摺動自在となるよう構成される。 Further, a pressing portion side first fitting portion 56 constituting a front-rear angle adjusting mechanism is provided at a location facing the base side second fitting portion 53 of the connecting portion 52. The pressing portion side first fitting portion 56 includes, for example, a concave second receiving portion having a substantially spherical shape. Further, a pressing portion 57 having a pressing portion side second fitting portion 58 corresponding to the pressing portion side first fitting portion 56 is provided. The pressing portion side second fitting portion 58 is, for example, a second abutting portion formed in a substantially hemispherical shape, and is configured to be slidable with respect to the second receiving portion.

すなわち、押さえ部５７は、連結部５２に対して摺動自在となるよう構成され、押さえ部側第１嵌合部５６に収容されており、略中央部には軸部５１の軸線に対して直交する前後方向に貫通孔５９が形成され、固定ボルトＢ３により支柱２０の基部４０と連結固定するものとしている。これにより、基部４０と押さえ部５７を連結固定した状態で、上下角度調整機構（基部側第１嵌合部４２、基部側第２嵌合部５３）及び前後角度調整機構（押さえ部側第１嵌合部５６、押さえ部側第２嵌合部５８）を介して、連結部材５０を摺動自在とすることができ、所定方向への角度調整を行うことができる。 That is, the pressing portion 57 is configured to be slidable with respect to the connecting portion 52 and is accommodated in the pressing portion side first fitting portion 56, and is substantially centered with respect to the axis of the shaft portion 51. Through holes 59 are formed in the front-rear direction perpendicular to each other, and are connected and fixed to the base portion 40 of the support column 20 with fixing bolts B3. Thereby, in a state where the base 40 and the pressing portion 57 are connected and fixed, the vertical angle adjusting mechanism (the base side first fitting portion 42, the base side second fitting portion 53) and the front and rear angle adjusting mechanism (the pressing portion side first) The connecting member 50 can be slidable via the fitting portion 56 and the pressing portion side second fitting portion 58), and the angle can be adjusted in a predetermined direction.

また、押さえ部側第１嵌合部５６に収容される押さえ部５７が脱落することがないよう、押さえ部５７の少なくとも一部を覆設するカバー部６０がネジＢ１にて連結部材５０に固定される。当該カバー部６０は、押さえ部５７の貫通孔５９に挿通される固定ボルトＢ３の妨げになることがないよう、押さえ部５７の外周縁部を覆設するべく、例えば、略Ｃ字状に形成にされるが、これに限られないのは勿論である。 Moreover, the cover part 60 which covers at least one part of the holding | suppressing part 57 is fixed to the connection member 50 with the screw | thread B1 so that the pressing part 57 accommodated in the holding | suppressing part side 1st fitting part 56 may not drop off. Is done. The cover portion 60 is formed, for example, in a substantially C shape so as to cover the outer peripheral edge portion of the pressing portion 57 so as not to hinder the fixing bolt B3 inserted into the through hole 59 of the pressing portion 57. Of course, it is not limited to this.

次に、防護柵１０の構築方法について説明する。支柱２０に対するビーム３０の取付作業は複数回行われるため、１本のビーム３０を取り付ける例のみを説明する。まず、２本の支柱２０を所定間隔を有した状態で地面Ｇに立設する。このとき、当該所定間隔は、ビーム３０の両端に設置される連結部材５０の相互が支柱２０内部に挿通可能な間隔としておく。 Next, a construction method of the protective fence 10 will be described. Since the work of attaching the beam 30 to the support column 20 is performed a plurality of times, only an example of attaching one beam 30 will be described. First, the two struts 20 are erected on the ground G with a predetermined interval. At this time, the predetermined interval is set such that the connecting members 50 installed at both ends of the beam 30 can be inserted into the column 20.

次に、図５に示すように、ビーム３０の挿通孔３１に連結部材５０の軸部５１を挿通し、ワッシャＷと取付孔３３を介して固定ボルトＢ２を軸部５１のネジ孔５４にねじ込んで、連結部材５０をビーム３０に対して仮止めした状態とする。このとき、取付孔３３を長孔状に形成することで、固定ボルトＢ２を長孔内で移動させることにより、連結部材５０をビーム３０の軸線方向に移動させて微調整を行うことができる。 Next, as shown in FIG. 5, the shaft portion 51 of the connecting member 50 is inserted into the insertion hole 31 of the beam 30, and the fixing bolt B <b> 2 is screwed into the screw hole 54 of the shaft portion 51 through the washer W and the mounting hole 33. Thus, the connecting member 50 is temporarily fixed to the beam 30. At this time, by forming the attachment hole 33 in the shape of a long hole, the connecting bolt 50 can be moved in the axial direction of the beam 30 by moving the fixing bolt B2 in the long hole, and fine adjustment can be performed.

そして、一方の支柱２０の挿通孔２１に対して、ビーム３０の一端の連結部材５０を挿通させて連結部材５０を支柱２０内部に配置させるとともに、ビーム３０の一端を支柱２０内部に配置させる。また、他方の支柱２０の挿通孔２１に対して、ビーム３０の他端の連結部材５０を挿通させて連結部材５０を支柱２０内部に配置させるとともに、ビーム３０の他端を支柱２０内部に配置させた状態とする。 Then, the connection member 50 at one end of the beam 30 is inserted into the insertion hole 21 of one of the columns 20 to place the connection member 50 inside the column 20, and one end of the beam 30 is arranged inside the column 20. Further, the connecting member 50 at the other end of the beam 30 is inserted into the insertion hole 21 of the other support column 20 so that the connecting member 50 is arranged inside the support column 20, and the other end of the beam 30 is arranged inside the support column 20. Let the state be

そして、夫々における連結部５２の基部側第２嵌合部５３（第１当接部）を夫々における基部４０の基部側第１嵌合部４２（第１受け部）に当接させ、固定ボルトＢ３を支柱２０の取付孔２２から支柱２０内部へと挿通させるとともに、押さえ部５７の貫通孔５９に挿通させる。このとき、基部側第２嵌合部５３（第１当接部）が基部側第１嵌合部４２（第１受け部）に対して摺動自在に当接されることから、支柱２０の軸線に対して直交する軸線を中心として、連結部材５０における上下方向の所定角度を調整することができる。更に、押さえ部側第２嵌合部５８（第２当接部）が押さえ部側第１嵌合部５６（第２受け部）に対して摺動自在に収容されることから、支柱２０の軸線に対して直交する軸線を中心として、連結部材５０における前後方向の所定角度を調整することができる。 And the base side 2nd fitting part 53 (1st contact part) of each connection part 52 is made to contact | abut to the base side 1st fitting part 42 (1st receiving part) of each base 40, and fixing bolt B3 is inserted from the attachment hole 22 of the support column 20 into the support column 20, and is also inserted through the through hole 59 of the pressing portion 57. At this time, the base-side second fitting portion 53 (first contact portion) is slidably contacted with the base-side first fitting portion 42 (first receiving portion). A predetermined angle in the vertical direction of the connecting member 50 can be adjusted around an axis perpendicular to the axis. Further, since the pressing portion side second fitting portion 58 (second contact portion) is slidably accommodated with respect to the pressing portion side first fitting portion 56 (second receiving portion), A predetermined angle in the front-rear direction of the connecting member 50 can be adjusted around an axis perpendicular to the axis.

そして、夫々の角度調整後に固定ボルトＢ３を基部４０のネジ孔４３にねじ込んで、基部４０と押さえ部５７にて連結部５２を挟持した状態で、連結部材５０を基部４０に固定する。最後に、ビーム３０の両端部が挿通孔３１より基部４０の内側方向に位置した状態となっていることを確認した後、ビーム３０の取付孔３３に対する固定ボルトＢ２の締め付けを行うとともに、ビーム用キャップ３４を切欠部３２に取り付け、支柱用キャップ２４を取付孔２２に取り付けることで、１本のビーム３０の取付作業が完了する。 Then, after each angle adjustment, the fixing bolt B3 is screwed into the screw hole 43 of the base portion 40, and the connecting member 50 is fixed to the base portion 40 with the connecting portion 52 held between the base portion 40 and the pressing portion 57. Finally, after confirming that both ends of the beam 30 are positioned inward of the base 40 from the insertion hole 31, the fixing bolt B2 is tightened to the mounting hole 33 of the beam 30, and the beam By attaching the cap 34 to the notch 32 and attaching the support cap 24 to the attachment hole 22, the work of attaching one beam 30 is completed.

また、支柱用キャップ２４及びビーム用キャップ３４には、支柱２０又はビーム３０から当該キャップを取り外す際にピン、レンチ等の工具が挿通可能となるよう小孔２５、３５が設けられており、これにより当該キャップを取り外すことで、内部のメンテナンス等を行うことができる。 The support cap 24 and the beam cap 34 are provided with small holes 25 and 35 so that a tool such as a pin or a wrench can be inserted when removing the cap from the support 20 or the beam 30. By removing the cap, the internal maintenance can be performed.

以上、説明した本発明に係る防護柵１０によれば、ビーム３０の両端部が支柱２０内部に収容されるとともに、固定ボルト等の固定手段が支柱２０及びビーム３０の外面に露呈することがないので、両者における外観の意匠性を向上させることができる。 As described above, according to the protective fence 10 according to the present invention described above, both ends of the beam 30 are accommodated in the support column 20 and fixing means such as fixing bolts are not exposed to the outer surfaces of the support column 20 and the beam 30. Therefore, the design of the external appearance in both can be improved.

また、仮にビーム３０側の固定ボルトＢ２が外れてしまった場合であっても、図３に示すように、連結部材５０に対するビーム３０の左右方向の仮想可動領域Ｄ１は、連結部材５０の軸部５１をビーム３０に挿通して設置する際の挿通領域Ｄ２より小さくなるよう設定されるので、連結部材５０の軸部５１から抜けることなく、軸部５１によって支持されるため、ビーム３０が脱落するのを防止することができる。 Even if the fixing bolt B2 on the beam 30 side is removed, the virtual movable region D1 in the left-right direction of the beam 30 with respect to the connecting member 50 is the axial portion of the connecting member 50 as shown in FIG. 51 is set so as to be smaller than the insertion region D2 when the beam 51 is inserted through the beam 30 and is supported by the shaft portion 51 without coming off the shaft portion 51 of the connecting member 50, so that the beam 30 falls off. Can be prevented.

更には、支柱２０内部にて、連結部材５０の基部側第２嵌合部５３（第１当接部）を基部４０の基部側第１嵌合部４２（第１受け部）に当接させた状態で、固定ボルトＢ３にて固定するだけでよいので、取付作業を容易なものとすることができ、施工性を向上させることができる。 Further, the base side second fitting portion 53 (first contact portion) of the connecting member 50 is brought into contact with the base side first fitting portion 42 (first receiving portion) of the base portion 40 inside the support column 20. In this state, it is only necessary to fix with the fixing bolt B3, so that the mounting operation can be facilitated and the workability can be improved.

当該発明は、上述の実施形態の構成に限定されるものではなく、支柱２０、ビーム３０、連結手段における基部４０及び連結部材５０の形状、寸法、材質等を適宜変更して実施することが可能である。例えば、基部４０は、取付板４１を介することなく、支柱２０の内壁に設置する構成とすることもできる。すなわち、支柱２０の内部にて、基部４０が内側方向に突出するようにして設置されていればよい趣旨である。 The present invention is not limited to the configuration of the above-described embodiment, and can be implemented by appropriately changing the shapes, dimensions, materials, and the like of the support column 20, the beam 30, the base 40 and the connecting member 50 in the connecting means. It is. For example, the base 40 may be configured to be installed on the inner wall of the support column 20 without using the mounting plate 41. That is, it is only necessary that the base 40 is installed inside the support column 20 so as to protrude inward.

また、基部４０は、支柱２０の取付孔２２から挿通される固定ボルトＢ３による取付作業が行い易いように前後方向に設置され、基部側第１嵌合部４２が取付孔２２に臨むようにして設けられるものであるが、これに限られるものではない。例えば、基部４０の基部側第１嵌合部４２を支柱２０の上方又は下方に向けるようにして設置することもできるし、その他所定角度を有した斜め方向等に設置することもできる。 Further, the base 40 is installed in the front-rear direction so that the attachment work by the fixing bolt B3 inserted through the attachment hole 22 of the support column 20 can be easily performed, and the base-side first fitting portion 42 is provided so as to face the attachment hole 22. However, it is not limited to this. For example, the base side first fitting portion 42 of the base portion 40 can be installed so as to face the upper side or the lower side of the support column 20, or can be installed in an oblique direction having a predetermined angle.

また、基部４０と連結部材５０の固定状態において、ビーム３０の両端部は支柱２０内部に収容されるものであるが、支柱２０の内部に形成される内部空間に当該両端部が位置するものに限られることなく、挿通孔２１が形成される領域内に位置するものであってもよいのは勿論である。すなわち、ビーム３０の両端部が支柱２０の外側に位置していなければよい趣旨である。 In addition, in the fixed state of the base 40 and the connecting member 50, both ends of the beam 30 are accommodated inside the column 20, but both ends are located in an internal space formed inside the column 20. Of course, it may be located in the region where the insertion hole 21 is formed without being limited thereto. In other words, both ends of the beam 30 should not be positioned outside the support column 20.

また、基部４０の基部側第１嵌合部４２（第１受け部）、連結部５２の基部４０側第２嵌合部５３（第１当接部）、押さえ部側第１嵌合部５６（第２受け部）、押さえ部５７の押さえ部側第２嵌合部５８（第２当接部）は、平滑な凹状、略球面状等に形成されることなく、作業者が一定の角度調整を行ったことを認識できるように、面上に凸部、凹部、突条、溝状等を適宜設けることもできる。 Further, the base side first fitting portion 42 (first receiving portion) of the base portion 40, the base portion 40 side second fitting portion 53 (first contact portion) of the connecting portion 52, and the pressing portion side first fitting portion 56. (Second receiving portion) The pressing portion side second fitting portion 58 (second abutting portion) of the pressing portion 57 is not formed in a smooth concave shape, a substantially spherical shape, or the like, and the operator can make a certain angle. In order to recognize that the adjustment has been performed, a convex portion, a concave portion, a protrusion, a groove shape, or the like can be appropriately provided on the surface.

また、図６に示すように、基部４０の基部側第１嵌合部４２、連結部５２の基部４０側第２嵌合部５３、押さえ部側第１嵌合部５６、押さえ部５７の押さえ部側第２嵌合部５８は、夫々が摺動自在となるよう構成される適宜の形状を組み合わせることができる。 Further, as shown in FIG. 6, the base side first fitting portion 42 of the base portion 40, the base portion 40 side second fitting portion 53, the pressing portion side first fitting portion 56, and the pressing portion 57 of the connecting portion 52 are pressed. The portion-side second fitting portion 58 can be combined with an appropriate shape configured to be slidable.

例えば、同図（ａ）に示すように、基部４０の基部側第１嵌合部４２を凸状の略球面状とし、連結部５２の基部側第２嵌合部５３を凹状の略球面状として、相互を摺動自在となるよう構成することもできる。また、連結部５２の押さえ部側第１嵌合部５６を凸状の略球面状とし、押さえ部５７の押さえ部側第２嵌合部５８を凹状の略球面状として、相互を摺動自在となるよう構成することもできる。更に、連結部５２に対して固定ボルトＢ３とともに押さえ部５７を取り付ける構成とすれば、カバー部６０を用いない構成とすることもできる。 For example, as shown in FIG. 5A, the base-side first fitting portion 42 of the base portion 40 has a convex substantially spherical shape, and the base-side second fitting portion 53 of the connecting portion 52 has a concave substantially spherical shape. As a result, they can be configured to be slidable with respect to each other. In addition, the pressing portion side first fitting portion 56 of the connecting portion 52 has a convex substantially spherical shape, and the pressing portion side second fitting portion 58 of the pressing portion 57 has a concave substantially spherical shape so that they can slide with each other. It can also be configured as follows. Furthermore, if it is set as the structure which attaches the press part 57 with the fixing bolt B3 with respect to the connection part 52, it can also be set as the structure which does not use the cover part 60. FIG.

また、同図（ｂ）に示すように、基部４０の基部側第１嵌合部４２を凸状の略球面状とし、連結部５２の基部側第２嵌合部５３を凹状の略球面状とするとともに、連結部５２の押さえ部側第１嵌合部５６を凹状の略球面状とし、押さえ部５７の押さえ部側第２嵌合部５８を凸状の略球面状として、相互を摺動自在となるよう構成することもできる。すなわち、支柱２０の軸線に対して直交する軸線を中心として上下方向、前後方向の所定角度にビーム３０を調整自在とするよう構成するものであれば、その形状は特に制限されるものではない。 Further, as shown in FIG. 5B, the base side first fitting portion 42 of the base portion 40 has a convex substantially spherical shape, and the base side second fitting portion 53 of the connecting portion 52 has a concave substantially spherical shape. In addition, the pressing portion side first fitting portion 56 of the connecting portion 52 has a concave substantially spherical shape, and the pressing portion side second fitting portion 58 of the pressing portion 57 has a convex substantially spherical shape, so that they slide each other. It can also be configured to be movable. That is, the shape of the beam 30 is not particularly limited as long as the beam 30 can be adjusted to a predetermined angle in the vertical direction and the front-rear direction about an axis orthogonal to the axis of the column 20.

また、一部構成を省略することができるし、一部抽出した構成とすることができるのは勿論である。 Of course, a part of the configuration can be omitted, and a part of the configuration can be extracted.
