Description

本発明は、歩車道境界などに設置される防護柵に関し、特に支柱の上端開口部に支柱キャップが取付けられた防護柵に関するものである。   The present invention relates to a protective fence installed at a pedestrian road boundary or the like, and particularly to a protective fence in which a support cap is attached to an upper end opening of a support.

一般に、防護柵、ガードフェンス等に用いられる支柱は、筒状の鋼材が多く用いられ、この支柱上部の開口部を塞ぐために、様々な支柱キャップが提案されている。支柱キャップは、一般には、溶接等により支柱上部に固定するものや、支柱上部に嵌合させるもの等が用いられている。   In general, a column used for a guard fence, a guard fence, or the like is often made of a cylindrical steel material, and various column caps have been proposed in order to close an opening of the column upper portion. In general, a pillar cap is fixed to the upper part of the pillar by welding or the like, or fitted to the upper part of the pillar.

そして、支柱キャップの頭部の形状として、例えば、意匠性を考慮してドーム状や球面状に形成された支柱キャップに関する柵支柱のキャップ取付構造が提案されている(例えば、特許文献1)。   And as the shape of the head of the column cap, for example, a fence column cap mounting structure related to a column cap formed in a dome shape or a spherical shape in consideration of design is proposed (for example, Patent Document 1).

又、円筒支柱の上部にレール受け頭部を設け、このレール受け頭部と円筒レールとの交差連結部において、レール受け頭部に樋状レール受けを取付けると共に、樋状レール受け内部に円筒支柱間に架設する円筒レールの端部を固定した道路用防護柵が提案されている(例えば、特許文献2)。

In addition, a rail receiving head is provided on the upper part of the cylindrical support, and at the intersection of the rail receiving head and the cylindrical rail, the saddle-shaped rail receiver is attached to the rail receiving head, and the cylindrical support is provided inside the saddle-shaped rail receiver. There has been proposed a road guard fence in which ends of cylindrical rails installed between them are fixed (for example, Patent Document 2).
JP-A-9-31932 JP-A-11-122718

しかしながら、特許文献1のように、このような支柱キャップを取付ると、一般的に支柱、横ビーム等はパイプ状のものを用いるため柵全体として平坦な箇所が少ないため、防護柵に誘導標識等の安全設備を後付けで取付ける場合に、取付ける場所を確保するのが困難であった。又、この柵において水平方向に延びる横ビーム材に対して、支柱キャップが飛び出した形状となるため、走行中の車等からこの柵越しに風景を眺める場合、この支柱キャップのために却って景観性を損ねる場合があった。   However, as shown in Patent Document 1, when such a support cap is attached, generally, the support post, the horizontal beam, etc. are pipe-shaped, so there are few flat parts as a whole of the fence. When installing safety equipment such as a retrofit, it was difficult to secure a place for installation. In addition, since the support cap protrudes from the horizontal beam material that extends in the horizontal direction on this fence, when looking at the scenery through this fence from a running car, etc. May be damaged.

又、特許文献2のように、円筒支柱の上部に設けたレール受け頭部によって円筒レールを支持する構造であると、円筒レールの高さに対してレール受け頭部の高さを合わせることができるので、景観性を向上させることは可能であるが、円筒レールに車等が衝突した場合、レール受け頭部が円筒支柱から外れ、衝突荷重を十分吸収できない恐れがあった。   Further, as in Patent Document 2, when the cylindrical rail is supported by the rail receiving head provided on the upper portion of the cylindrical support, the height of the rail receiving head can be adjusted to the height of the cylindrical rail. Although it is possible to improve the scenery, when a car or the like collides with the cylindrical rail, the rail receiving head may come off from the cylindrical column and the collision load may not be sufficiently absorbed.

本発明は、前記の如き問題点を解消し、誘導標識等の安全設備を安定よく載置することができる共に、景観性にも配慮した防護柵を提供せんとするものである。   The present invention is intended to solve the above-described problems and provide a protective fence that can stably place safety equipment such as a guide sign and also considers landscape.

上記目的を達成するために、本発明は次のような構成としている。
すなわちこの発明に係る防護柵は、間隔を置いて立設された支柱に支持部材を介してビーム材が取付けられ、該支柱の上端に取付けられた支柱キャップの頭部上面は、中央に平坦な平坦部が形成されると共に、該平坦部から頭部周縁に向けて傾斜状に下がる傾斜部が形成されていると共に、前記平坦部から前記支持部材に向けて延びる帯状部が形成されていることを特徴とするものである。
In order to achieve the above object, the present invention is configured as follows.
That is, the guard fence according to the present invention is such that the beam material is attached to the support columns that are erected at intervals, via the support member, and the upper surface of the head of the support cap attached to the upper end of the support post is flat in the center. A flat portion is formed, an inclined portion that is inclined downward from the flat portion toward the head periphery is formed, and a belt-like portion that extends from the flat portion toward the support member is formed. It is characterized by.

本発明によれば、「支柱キャップの頭部中央に平坦な平坦部が形成されていると共に、前記平坦部から前記支持部材に向けて延びる帯状部が形成されているので、該平坦部に誘導標識等の安全設備を安定よく載置することができ、しかも前記平坦部から頭部周縁に向けて傾斜状に下がる傾斜部が形成されているので、雨天時においては雨水が傾斜部を伝って下方に落下し、雨水の溜まる恐れが無く、さらに平坦部は傾斜部の上端に位置するので、これに載置する安全設備も見えやすく、支柱キャップが必要以上に上方に向けて突出することがない」等と言った顕著な効果を期待することができる。 According to the present invention, “a flat flat portion is formed at the center of the head of the support cap, and a belt-like portion extending from the flat portion toward the support member is formed. Safety equipment such as signs can be placed stably, and since an inclined part is formed that slopes downward from the flat part toward the periphery of the head, rainwater travels through the inclined part during rainy weather. There is no risk of falling down and collecting rainwater, and since the flat part is located at the upper end of the inclined part, it is easy to see the safety equipment placed on it, and the column cap may protrude upwards more than necessary. A remarkable effect such as “No” can be expected.

本発明に係る防護柵において、支持部材の幅と同じ帯状部が平坦部から前記支持部材に向けて形成されるようになされれば、支柱キャップの平坦部、帯状部及び支持部材の上面を跨ぐようにして、比較的大きな誘導標識等の安全設備を載置することができ、又帯状部によって、支柱キャップと支持部材とが連続することにより、見た目において両者の一体感が出、意匠的にも優れたものとなる。   In the guard fence according to the present invention, if the belt-shaped portion having the same width as the support member is formed from the flat portion toward the support member, the flat portion of the support cap, the belt-shaped portion, and the upper surface of the support member are straddled. In this way, safety equipment such as a relatively large guide sign can be placed, and the support member and the support member are continuous by the belt-like portion, so that a sense of unity between the two appears in appearance. Will also be excellent.

次に、本発明を実施するための最良の形態について図面を参照し、具体的に説明する。   Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

In addition, the beam members 2 are connected to each other at the connecting portions of the side end portions adjacent to each other via connecting fittings 21 inserted and fixed to the end portions of the respective beam members 2 as shown in FIG. .

次に、図2は、図1の縦断面の部分拡大図であり、(a)は図1のA−A断面の主要部、(b)は図1のB−B断面の主要部、(c)は(a)の縦断面の主要部を示すものである。支持部材3は、(a)に示すように、支柱1に固定される平板状の垂直板部31と、ビーム材2が支えられる支え部32とからなる。この垂直板部31は、背面側で支柱1に当接されると共に、支柱1を横方向に貫通する貫通ボルト4が貫通され、この貫通ボルト4に螺合されたナットAを締め付けることにより、垂直板部31が支柱1の外周面に固定され、これにより、支持部材3は支柱1に取付けられる。   Next, FIG. 2 is a partially enlarged view of the vertical cross section of FIG. 1, (a) is a main part of the AA cross section of FIG. 1, (b) is a main part of the BB cross section of FIG. c) shows the main part of the longitudinal section of (a). The support member 3 includes a flat plate-like vertical plate portion 31 fixed to the support column 1 and a support portion 32 on which the beam material 2 is supported, as shown in FIG. The vertical plate portion 31 is in contact with the support column 1 on the back side, and a through bolt 4 penetrating the support column 1 in the lateral direction is penetrated. By tightening the nut A screwed into the through bolt 4, The vertical plate portion 31 is fixed to the outer peripheral surface of the support column 1, whereby the support member 3 is attached to the support column 1.

支持部材3の支え部32は、図1及び図2の(a)に示すように、垂直板部31の前面側の上端部及び下端部から前方に向けて突設された上板部33、下板部34とによりビーム材2を支えるものである。本実施形態では、ビーム材2を接続する接続部21が上板部33と下板部34との間に配置され、上板部33、接続部21、及び下板部34を上下に貫通する固定ボルトBのナットCを締め付けて、上板部33と下板部34とにより接続部21を挟持するものである。そして、上板部33と下板部34の端部はそれぞれ内側に曲折された湾曲部35、36が形成され、この湾曲部35、36の外径は、ビーム材2の外径と同程度となされている。これらの構造により、接続部21が支え部32の内側に隠蔽されると共に、ビーム材2の前面側と支え部32の前面側とが略面一となされ、意匠性を高めることができる。尚、上板部33と下板部34との間にビーム材2を挿入挟持される形態でもよい。 As shown in FIG. 1 and FIG. 2A, the support portion 32 of the support member 3 includes an upper plate portion 33 projecting forward from an upper end portion and a lower end portion on the front surface side of the vertical plate portion 31. The beam member 2 is supported by the lower plate portion 34. In this embodiment, the connection part 21 which connects the beam material 2 is arrange | positioned between the upper board part 33 and the lower board part 34, and penetrates the upper board part 33, the connection part 21, and the lower board part 34 up and down. The nut C of the fixing bolt B is tightened, and the connecting portion 21 is sandwiched between the upper plate portion 33 and the lower plate portion 34. The end portions of the upper plate portion 33 and the lower plate portion 34 are respectively formed with bent portions 35 and 36 that are bent inward, and the outer diameters of the bent portions 35 and 36 are approximately the same as the outer diameter of the beam member 2. It has been. With these structures, the connection part 21 is concealed inside the support part 32, and the front side of the beam member 2 and the front side of the support part 32 are substantially flush with each other, so that the design can be improved. Note that the beam member 2 may be inserted and sandwiched between the upper plate portion 33 and the lower plate portion 34.

又、支柱1の間の距離が比較的長い場合は、本実施形態のように、支柱1と支柱1との間に支柱1Aを設け、ビーム材2の中間部を支柱1Aに取付けた支持部材3Aで支えるようにしてもよい。すなわち、図2の(b)に示すように、支持部材3Aにおいて、垂直板部31の上部から上板部33を突設し、この上板部33の端部を下方に曲折し、さらにその先端を前方に向けて円弧状に折り返して縦断面J字状に形成し、このJ字状部の上にビーム材2を載置し、ビーム材2とJ字状部とを固定ボルトBで連結して固定してもよい。   Further, when the distance between the columns 1 is relatively long, a support member in which a column 1A is provided between the column 1 and the column 1 and an intermediate portion of the beam member 2 is attached to the column 1A as in this embodiment. You may make it support by 3A. That is, as shown in FIG. 2 (b), in the support member 3A, the upper plate portion 33 is projected from the upper portion of the vertical plate portion 31, the end portion of the upper plate portion 33 is bent downward, and further The front end is folded back in an arc shape to form a J-shaped longitudinal section, the beam material 2 is placed on the J-shaped portion, and the beam material 2 and the J-shaped portion are fixed with a fixing bolt B. You may connect and fix.

図3〜4は、図1において、支柱1の上部に取付けられた支柱キャップ5の実施の一形態を示す説明図であり、図3は支柱キャップ5の斜視図、図4の(a)は、支柱キャップ5の正面図、(b)は底面図、(c)は(a)のC−C断面を示す縦断面図である。尚、(b)において、支柱1の上端12が配置される箇所を合わせて示している。支柱キャップ5は、支柱1の上部を隠蔽する頭部6と、支柱1の上端部から内部に挿入される挿入部7とを備えている。頭部6は略円盤状に形成されると共に、頭部6の周端部から下方に向けてリング状の裾部61が形成されている。   3-4 is explanatory drawing which shows one Embodiment of the support | pillar cap 5 attached to the upper part of the support | pillar 1 in FIG. 1, FIG. 3 is a perspective view of the support | pillar cap 5, (a) of FIG. The front view of the support | pillar cap 5, (b) is a bottom view, (c) is a longitudinal cross-sectional view which shows CC cross section of (a). In addition, in (b), the location where the upper end 12 of the support | pillar 1 is arrange | positioned is shown collectively. The support cap 5 includes a head 6 that conceals the upper part of the support 1 and an insertion portion 7 that is inserted into the support 1 from the upper end. The head 6 is formed in a substantially disk shape, and a ring-shaped hem 61 is formed downward from the peripheral end of the head 6.

図2の(c)及び図4の(b)に示すように、支柱1(支柱1の上端12)の外周面と前記裾部61の内周面との間には隙間S1が設けられている。これにより、例えば、支柱1を地面等に取付ける際に、ハンマー等の工具で支柱1の上部を叩いて支柱1の高さを調整すると、支柱1の上端部が潰れて外径が大きくなる場合があり、この場合でも、裾部61と支柱1とが干渉せずに、支柱キャップ5を支柱1に取付けることができる。   As shown in FIG. 2C and FIG. 4B, a gap S1 is provided between the outer peripheral surface of the support column 1 (the upper end 12 of the support column 1) and the inner peripheral surface of the skirt 61. Yes. Thereby, for example, when attaching the support column 1 to the ground or the like, if the height of the support column 1 is adjusted by hitting the upper part of the support column 1 with a tool such as a hammer, the upper end of the support column 1 is crushed and the outer diameter increases. Even in this case, the column cap 5 can be attached to the column 1 without interference between the skirt 61 and the column 1.

次に、支持部材3と支柱キャップ5の頭部6との関係について詳しく説明する。図6は、図1の支柱1付近の拡大平面図であり、(a)は支柱キャップ5を取付ける前、(b)は支柱キャップ5を取付けた後の一実施形態をそれぞれ示すものである。図3に示すように、頭部6の裾部61には下端から切欠部62が設けられている。これにより、(a)に示すように、支柱1と支持部材3の垂直板部31との当接部11に前記切欠部62を差し込めば、支柱キャップ5を支柱1に取付けることが可能となる。従って、支持部材3を支柱1の側面に直接的に固定できるので、支持部材3と支柱1との間に支柱キャップ5の裾部61が挟み込まれて、裾部61に割れや破損等の不具合が起こるような恐れがなく、又、支柱1に支持部材3を取付けた後に支柱キャップ5を取付けることが可能であり、逆に、支柱1に支柱キャップ5を取付けた後に支持部材3を取付けることも可能となる。 Next, the relationship between the support member 3 and the head 6 of the column cap 5 will be described in detail. 6 is an enlarged plan view of the vicinity of the support column 1 in FIG. 1, (a) shows an embodiment before the support cap 5 is attached, and (b) shows an embodiment after the support cap 5 is attached. As shown in FIG. 3, a hem 61 of the head 6 is provided with a notch 62 from the lower end. Thus, it is possible to attach (a), the Simply slide the notch 62 to the contact portion 11 of the vertical plate portion 31 of the post 1 and the support member 3, the strut cap 5 to the post 1 . Accordingly, since the support member 3 can be directly fixed to the side surface of the support column 1, the skirt portion 61 of the support cap 5 is sandwiched between the support member 3 and the support column 1, and the hem portion 61 is broken or damaged. It is possible to attach the support cap 3 after attaching the support member 3 to the support 1, and conversely, attaching the support member 3 after attaching the support cap 5 to the support 1. Is also possible.

又、図4、図6、図7に示すように、支柱キャップ5の頭部6上面は、中央に平坦な平坦部63が形成されている。これにより、図8に示すように、平坦部63に安全設備Sを安定よく載置することができる。そして、この平坦部63から支持部材3に向けて延びる帯状部64が形成され裾部61に達し、この裾部61から支持部材3に向けて厚肉部65が形成され、支柱1と支持部材3との間に生じた平面視三角形状の隙間S2が埋められている。この厚肉部65により、支柱1に対する支柱部材3の前後方向のがたつきを抑えることができる。加えて、支柱キャップ5の頭部6は、支持部材3を介して支柱1に取付けられるビーム材2に対する上方への突出を抑えることができ、防護柵全体としての景観性を高めることができる。   As shown in FIGS. 4, 6, and 7, the upper surface of the head 6 of the support cap 5 is formed with a flat portion 63 at the center. Thereby, as shown in FIG. 8, the safety equipment S can be stably placed on the flat portion 63. And the strip | belt-shaped part 64 extended toward the support member 3 from this flat part 63 is formed, and reaches the skirt part 61, and the thick part 65 is formed toward the support member 3 from this skirt part 61, and the support | pillar 1 and the support member A gap S2 having a triangular shape in plan view generated between the gap 3 and the gap 3 is filled. By this thick portion 65, the back-and-forth of the support member 3 with respect to the support 1 can be suppressed. In addition, the head 6 of the column cap 5 can suppress upward protrusion of the beam member 2 attached to the column 1 via the support member 3, and can enhance the scenery as the entire protective fence.

更に、平坦部63から厚肉部65に掛けて平面視略U字状に形成されていると共に、平坦部63から厚肉部65に掛けての幅寸法H1は、支持部材3の幅寸法H2と一致している。これにより、平面視において支持部材3と平坦部63とが同幅で繋がっている外観となり意匠性を高めることができる。又、図9に示すように、平坦部63から帯状部64を通って支持部材3に掛けて平坦に形成されている。これにより、平坦部63、帯状部64及び支持部材3の上面を跨ぐようにして、比較的大きな安全設備Sを載置することができる。尚、幅寸法H1と幅寸法H2とは意匠としては一致している方が好ましいが、少なくとも安全設備Sを安定よく載置できる幅寸法が確保されていればよい。又、帯状部64の上面は幅方向において断面直線上の平坦であればよく、長手方向には傾斜が生じていてもよい。これにより、帯状部64の上面が球面状に形成される場合に比べて、安全設備Sの下面を帯状部64の傾斜に合わせて加工する際に、その加工が比較的容易である。そして、両面テープ等を介して安全装置Sを載置する際に、両面テープ等の貼付作業において、両面テープ等の浮きやしわ等の不具合が発生しにくくなる。尚、安全装置Sは、支持部材3及び支柱キャップ5上に載置固定可能であれば、特に限定されるものではなく、再帰反射性標識体や太陽電池等を利用した自発光標識体を取付けてもよい。又、安全装置Sと支持部材3、平坦部63、帯状部64とを接着させる手段は、両面テープ、接着剤等を適宜選択することができる。   Furthermore, it is formed in a substantially U shape in plan view from the flat part 63 to the thick part 65, and the width dimension H1 from the flat part 63 to the thick part 65 is the width dimension H2 of the support member 3. Is consistent with Thereby, it becomes the external appearance which the support member 3 and the flat part 63 are connected by the same width in planar view, and can improve the designability. Further, as shown in FIG. 9, the flat portion 63 passes through the belt-like portion 64 and is hung on the support member 3 to be flat. Thereby, the comparatively big safety equipment S can be mounted so that the flat part 63, the strip | belt-shaped part 64, and the upper surface of the supporting member 3 may be straddled. Although it is preferable that the width dimension H1 and the width dimension H2 coincide with each other as a design, it is sufficient that at least a width dimension capable of stably placing the safety equipment S is secured. Moreover, the upper surface of the strip | belt-shaped part 64 should just be flat on a cross-sectional straight line in the width direction, and the inclination may arise in the longitudinal direction. Thereby, compared with the case where the upper surface of the strip-shaped portion 64 is formed in a spherical shape, when the lower surface of the safety equipment S is processed according to the inclination of the strip-shaped portion 64, the processing is relatively easy. When the safety device S is placed via a double-sided tape or the like, problems such as lifting or wrinkling of the double-sided tape or the like are less likely to occur in the attaching operation of the double-sided tape or the like. The safety device S is not particularly limited as long as the safety device S can be placed and fixed on the support member 3 and the column cap 5, and a self-luminous marker using a retroreflective marker or a solar cell is attached. May be. Further, as a means for bonding the safety device S to the support member 3, the flat portion 63, and the belt-shaped portion 64, a double-sided tape, an adhesive, or the like can be appropriately selected.

更に支柱キャップ5の頭部6上面は、平坦部63及び帯状部64以外の箇所は、平坦部63から頭部6の周縁に向けて傾斜状に下がる傾斜部66が形成されている。これにより、雨天時においては雨水が傾斜部66を伝って下方に落下し、雨水の溜まる恐れが無く、又平坦部は傾斜部の上端に位置するので、これに載置する安全設備Sも見えやすくすることができる。   Further, on the upper surface of the head 6 of the column cap 5, an inclined portion 66 that is inclined downward from the flat portion 63 toward the periphery of the head 6 is formed at portions other than the flat portion 63 and the belt-like portion 64. Thereby, in rainy weather, rainwater falls down along the inclined portion 66 and there is no risk of rainwater collecting, and since the flat portion is located at the upper end of the inclined portion, the safety equipment S placed on this is also visible. It can be made easier.

又、支持部材3の垂直板部31の背面は垂直方向に平坦に形成されていると共に、この平坦部と向き合う厚肉部65の前面も同様に平坦に形成されている。これにより、支持部材3は、垂直板部31を貫通する貫通ボルト4を軸にして回動可能であり、設置場所が傾斜地であっても、その傾斜に応じて支持部材3を回動させてビーム材2を取付けることが可能であり、更に、支持部材3を回動させた状態であっても、支柱キャップ5を取付けることが可能となる。   Further, the back surface of the vertical plate portion 31 of the support member 3 is formed flat in the vertical direction, and the front surface of the thick portion 65 facing the flat portion is also formed flat. Thereby, the support member 3 can be rotated around the through bolt 4 penetrating the vertical plate portion 31, and the support member 3 can be rotated according to the inclination even if the installation place is an inclined place. The beam member 2 can be attached, and the support cap 5 can be attached even when the support member 3 is rotated.

次に、支柱キャップ5の挿入部7について説明する、挿入部7は、頭部6の下面に設けられ裾部61と同円心の円筒状に形成された垂下片8を備えている。本実施形態では、図4の(b)、(c)に示すように、垂下片8の内部において、頭部6の下面から下方に向けて垂下片8と同円心の円筒状リブ71が複数設けられ、更に中心部の円筒状リブ71から垂下片8の内周面に向けて放射状に補強リブ72が設けられている。これにより、頭部41及び垂下片43の剛性を高めることができる。   Next, the insertion portion 7 of the support cap 5 will be described. The insertion portion 7 includes a hanging piece 8 provided on the lower surface of the head 6 and formed in a cylindrical shape that is concentric with the skirt 61. In the present embodiment, as shown in FIGS. 4B and 4C, cylindrical ribs 71 that are concentric with the drooping piece 8 are formed inside the drooping piece 8 from the lower surface of the head 6 downward. A plurality of reinforcing ribs 72 are provided radially from the central cylindrical rib 71 toward the inner peripheral surface of the hanging piece 8. Thereby, the rigidity of the head 41 and the hanging piece 43 can be increased.

垂下片8は、図3〜4に示すように、円筒状部の下端から上方に向けて収納溝81が形成されている。収納溝81は、貫通ボルト4が横から差し込まれる差込口82と、差込口82の奥部に形成され、貫通ボルト4が横方向で収納されるボルト収納部83とからなる。   As shown in FIGS. 3 to 4, the hanging piece 8 has a storage groove 81 formed upward from the lower end of the cylindrical portion. The storage groove 81 includes an insertion port 82 into which the through bolt 4 is inserted from the side, and a bolt storage unit 83 that is formed at the back of the insertion port 82 and stores the through bolt 4 in the horizontal direction.

収納溝81の両側には、垂下片8の外周面から支柱1の内周面に向けて縦リブ84が設けられている。そして、垂下片8を支柱1の内部に挿入した際に、縦リブ84の先端が支柱1の内周面に当接するようになされている。又、収納溝81と縦リブ84との間には、貫通ボルト4の螺子部41が横から差込口82に差し込まれた際に、押圧変形して貫通ボルト4の螺子部41をボルト収納部83に導く変形部85が形成されている。   On both sides of the storage groove 81, vertical ribs 84 are provided from the outer peripheral surface of the hanging piece 8 toward the inner peripheral surface of the column 1. And when the drooping piece 8 is inserted into the inside of the column 1, the tips of the vertical ribs 84 come into contact with the inner peripheral surface of the column 1. Further, when the screw portion 41 of the through bolt 4 is inserted into the insertion port 82 from the side between the storage groove 81 and the vertical rib 84, the screw portion 41 of the through bolt 4 is stored in the bolt by being deformed by pressing. A deformation portion 85 that leads to the portion 83 is formed.

次に、支柱1に対する支柱キャップ5の取付方法について詳しく説明する。図5に示すように、まず、支柱キャップ5の挿入部7(垂下片8)を支柱1の上端部から内部に挿入し、支柱1を横方向に貫通する貫通ボルト4の螺子部41が垂下片8の収納溝81の差込口82に横から差し込まれるようにする。本実施形態では、差込口82は、開口端部の幅寸法が貫通ボルト4の螺子部41の幅寸法より大きく、奥部の幅寸法は螺子部41の幅寸法より小さい略二等辺三角形状となされている。従って、螺子部41は、差込口82の奥部に進みにつれて両側の変形部85に当接し、更に奥部に進むと変形部85を押圧変形させ、最奥部のボルト収納部83に達すると、変形部85は貫通ボルト4から受ける押圧がなくなり、変形前の元の状態に戻る。これにより、貫通ボルト4の螺子部41がボルト収納部83に収納され、支柱キャップ5が貫通ボルト4に係止される。ボルト収納部83の大きさは螺子部41の外形と同程度かやや大きい程度で、支柱キャップ5が貫通ボルト4に係止された状態において、上下方向に不必要に移動しない程度が好ましい。   Next, a method for attaching the column cap 5 to the column 1 will be described in detail. As shown in FIG. 5, first, the insertion portion 7 (hanging piece 8) of the column cap 5 is inserted into the inside from the upper end portion of the column 1, and the screw portion 41 of the through bolt 4 penetrating the column 1 laterally is suspended. It is inserted from the side into the insertion port 82 of the storage groove 81 of the piece 8. In the present embodiment, the insertion port 82 has a substantially isosceles triangular shape in which the width dimension of the opening end is larger than the width dimension of the screw part 41 of the through bolt 4 and the width dimension of the inner part is smaller than the width dimension of the screw part 41. It has been. Accordingly, the screw portion 41 abuts against the deformed portions 85 on both sides as it goes to the inner portion of the insertion port 82, and further presses and deforms the deformable portion 85 when it further moves to the inner portion, reaching the innermost bolt housing portion 83. Then, the deforming portion 85 is not pressed from the through bolt 4 and returns to the original state before the deformation. As a result, the screw portion 41 of the through bolt 4 is stored in the bolt storage portion 83, and the support cap 5 is locked to the through bolt 4. The size of the bolt storage portion 83 is preferably the same as or slightly larger than the outer shape of the screw portion 41, and preferably does not unnecessarily move in the vertical direction when the support cap 5 is locked to the through bolt 4.

次に、垂下片8における変形部85と縦リブ84との関係について詳しく説明する。本実施形態では、変形部85は横断面円弧状に形成されているため、貫通ボルト4の螺子部41から押圧を受けると、差込口82の幅を広げるように外方に向けて変形する。この際、縦リブ84は支柱1の内周面に当接されているため、この変形部85の変形を抑制するように作用する。先ず、貫通ボルト4が差込口82に挿入される際は、差込口82が略三角形状であり、押圧に伴う変形が徐々に生じるため、垂下片8全体でその変形を分散して受けることが比較的容易であり、貫通ボルト4をボルト収納部83に導くことが可能となる。一方、貫通ボルト4をボルト収納部83から引き出す場合は、最初に差込口82において最も幅狭の箇所を広げる必要があるため、比較的大きな変形が必要となるが、この際、縦リブ84が支柱1の内周面に向けて押圧され、そしてこの内周面に当接されることによりこの変形が抑制され、容易には抜け出さなくなる。従って、変形部85と縦リブ84とによって、貫通ボルト4をボルト収納部83に安定的に収納され、支柱キャップ5が支柱1から容易に抜け出さなくなる。   Next, the relationship between the deforming portion 85 and the vertical rib 84 in the hanging piece 8 will be described in detail. In the present embodiment, since the deforming portion 85 is formed in an arc shape in cross section, when the pressing is received from the screw portion 41 of the through bolt 4, the deforming portion 85 is deformed outward so as to widen the insertion port 82. . At this time, since the vertical rib 84 is in contact with the inner peripheral surface of the support column 1, it acts to suppress the deformation of the deforming portion 85. First, when the through bolt 4 is inserted into the insertion port 82, the insertion port 82 has a substantially triangular shape, and deformation due to pressing gradually occurs. Therefore, the deformation is distributed and received by the entire hanging piece 8. It is relatively easy, and the through bolt 4 can be guided to the bolt housing 83. On the other hand, when the through bolt 4 is pulled out from the bolt housing portion 83, it is necessary to first widen the narrowest part in the insertion port 82, so that a relatively large deformation is required. Is pressed toward the inner peripheral surface of the column 1 and is brought into contact with the inner peripheral surface, so that this deformation is suppressed and it cannot be easily pulled out. Accordingly, the through bolt 4 is stably housed in the bolt housing portion 83 by the deforming portion 85 and the vertical rib 84, and the support cap 5 does not easily come out of the support 1.

垂下片8は、本形態では円筒状に形成されており、収納溝81は垂下片8において相対して2個形成されている。これにより、支柱キャップ5は2個の収納溝81に貫通ボルト4が収納されるので、支柱1に対して支柱キャップ5をより強固に取付けることができる。   The drooping piece 8 is formed in a cylindrical shape in this embodiment, and two storage grooves 81 are formed in the drooping piece 8 so as to face each other. Thereby, since the penetration bolt 4 is accommodated in the two accommodation grooves 81, the support cap 5 can be attached to the support 1 more firmly.

このように、垂下片8の収納溝81と縦リブ84との相乗的効果により、支柱キャップ5を支柱1に強固に取付けることができ、本発明に係る防護柵Pに自動車等の車両が衝突しても、支柱キャップ5は支柱1から容易に外れず、周囲に飛散して2次災害を起こすような可能性を低くすることができる。   Thus, the support cap 5 can be firmly attached to the support 1 by the synergistic effect of the storage groove 81 and the vertical rib 84 of the hanging piece 8, and a vehicle such as an automobile collides with the protective fence P according to the present invention. Even so, it is possible to reduce the possibility that the column cap 5 does not easily come off the column 1 and scatters around and causes a secondary disaster.

又、貫通ボルト4の貫通方向と、支柱キャップ5の頭部6において頭部平坦部63の延設方向とが一致している。これにより、支柱1に貫通ボルト4が貫通され、更に支持部材3が支柱1に取付けられた状態で支柱キャップ5を取付ける際、支柱キャップ5の頭部6の向きは支持部材3によって規制されるので、その向きで支柱キャップ5を挿入した際に、貫通ボルト4と係止するように垂下片8の収納溝81を予め設定しておけば、支柱キャップ5の頭部6の向き合わせは不要となり、取付作業が容易となる。   Further, the penetrating direction of the penetrating bolt 4 coincides with the extending direction of the head flat portion 63 in the head 6 of the column cap 5. As a result, the orientation of the head 6 of the support cap 5 is regulated by the support member 3 when the support cap 3 is attached with the through bolt 4 passing through the support 1 and the support member 3 attached to the support 1. Therefore, if the storage groove 81 of the hanging piece 8 is set in advance so as to be engaged with the through bolt 4 when the support cap 5 is inserted in that direction, the head 6 of the support cap 5 need not be faced. Thus, the mounting work becomes easy.

支柱キャップ5の取付方法は上記に限定されるものではなく、例えば、支柱1に支柱キャップ5の挿入部7(垂下片8)を挿入した後に、支柱1に貫通ボルト4を横方向に貫通させ、この際に、貫通ボルト4が収納溝81のボルト収納部83を貫通するように取付けてもよい。   The attachment method of the support cap 5 is not limited to the above. For example, after the insertion portion 7 (the hanging piece 8) of the support cap 5 is inserted into the support 1, the through bolt 4 is passed through the support 1 in the lateral direction. At this time, the through bolt 4 may be attached so as to penetrate the bolt housing portion 83 of the housing groove 81.

支柱1は、ビーム材2を支えることを考慮すると金属製のものを用いるのが好ましく、一般にはアルミニウム、ステンレス、鉄鋼等のパイプ、形材からなる長尺体を適宜長さに切断したものや、それらにめっき、塗装を施したもの等を好適に用いることができる。   The column 1 is preferably made of metal in consideration of supporting the beam member 2, and generally, a long body made of a pipe or a shape member made of aluminum, stainless steel, steel, or the like is cut into an appropriate length.

Moreover, the thing of the vertical lattice shape which has arrange | positioned the vertical beam between the beam materials 2 may be sufficient, and the thing which arrange | positioned the mesh panel similarly may be sufficient.

支持部材3は、ビーム材2を支えることを考慮すると金属製のものを用いるのが好ましく、一般にはアルミニウム、ステンレス、鉄鋼等の金属板をプレス成形加工したものや、それらにめっき、塗装を施したもの等を好適に用いることができる。又、支持部材3に取付けられる連結ボルトBの頭部を隠蔽するために、支持部材3の上部にカバー材を取付けてもよい。カバー材において、防護柵Pの長手方向に向けて略垂直に配置した反射材を取付けてもよい。カバー材は支持部材3のそれぞれに取付けてもよく、又、自動車のヘッドライトの位置を考慮して下部の支持部材3のみに取付けてもよい。   Considering that the beam member 2 is supported, it is preferable to use a metal member for the support member 3. In general, a metal plate such as aluminum, stainless steel, or steel is press-molded, or plated or painted. The thing etc. which can be used can be used suitably. Further, a cover material may be attached to the upper part of the support member 3 in order to conceal the head of the connecting bolt B attached to the support member 3. In the cover material, a reflective material arranged substantially vertically toward the longitudinal direction of the protective fence P may be attached. The cover material may be attached to each of the support members 3, or may be attached only to the lower support member 3 in consideration of the position of the headlight of the automobile.

支柱キャップ5は、一般には合成樹脂を射出成形して一体的に形成されたものであり、合成樹脂としては、ポリカーボネート、ウレタン樹脂、ポリアセタール、ポリエステル、AAS樹脂、ABS樹脂、ポリアミド等を単独で用いてもよく、これらを適宜組み合わせて用いてもよい。又、複数の部材を組み合わせて形成してもよい。   The support cap 5 is generally integrally formed by injection molding a synthetic resin. As the synthetic resin, polycarbonate, urethane resin, polyacetal, polyester, AAS resin, ABS resin, polyamide, etc. are used alone. These may be used in appropriate combination. Moreover, you may form combining several members.
