この発明の防護柵用横ビーム取付金具の一実施態様を、図面を参照しながら説明する。   One embodiment of a guard fence lateral beam fitting of the present invention will be described with reference to the drawings.

図１は、この発明の防護柵用横ビーム取付金具を示す平面図、図２は、この発明の防護柵用横ビーム取付金具を示す正面図、図３は、図１のＡ矢視図である。   FIG. 1 is a plan view showing the side fence attachment for guard fence of the present invention, FIG. 2 is a front view showing the side beam attachment for guard fence according to the present invention, and FIG. is there.

図１から図３に示すように、この発明の防護柵用横ビーム取付金具Ｃ（以下、単に横ビーム取付金具Ｃという。）は、板材としての鋼板をＵ字状に折り曲げることにより、支柱に巻き付けられるバンド部１と横ビームが取り付けられる横ビーム取付部２とが形成されたものからなっている。なお、バンド部１の内径は、取り付ける支柱の外径より若干小さく形成されている。また、横ビーム取付部２は、対向して形成され、横ビーム取付部２間に横ビームの端部が挟み込まれ、後述する横ビーム取付ボルトにより固定される。   As shown in FIG. 1 to FIG. 3, the guard beam horizontal beam mounting bracket C of the present invention (hereinafter simply referred to as horizontal beam mounting bracket C) is a support by bending a steel plate as a plate into a U shape. It comprises a band 1 to be wound and a cross beam attachment 2 to which a cross beam is attached. In addition, the internal diameter of the band part 1 is formed a little smaller than the outer diameter of the support | pillar to attach. Further, the lateral beam mounting portions 2 are formed to face each other, and the end portions of the lateral beams are sandwiched between the lateral beam mounting portions 2 and fixed by lateral beam mounting bolts described later.

バンド部１の内面には、支柱に形成された後述する開口に係合する突起３が形成され、横ビーム取付部２には、横ビーム取付ボルトが挿通されるボルト孔４が形成されている。   A projection 3 is formed on the inner surface of the band portion 1 to be engaged with an opening described later formed in a support, and a bolt hole 4 through which a horizontal beam mounting bolt is inserted is formed in the horizontal beam mounting portion 2 .

ボルト孔４は、後述するように、横ビーム取付金具Ｃを上下反転して使用する場合において、支柱への横ビームの取り付け部分の外観を良くするために、突起３を通る中心線（Ｌ）より外側に形成されている。なお、５は、補強用エンボスである。   The bolt hole 4 is a center line (L) passing through the projection 3 in order to improve the appearance of the mounting portion of the cross beam to the support when the cross beam mounting bracket C is used upside down as described later. It is formed more outward. In addition, 5 is an embossing for reinforcement.

突起３は、バンド部１をプレスにより打ち抜き、バンド部１の一部をバンド部１の内側に直角に折り曲げることにより形成され、先端には、フック６が形成されている。突起３は、左右に一対形成され、一対のフック６は、上下外向きに形成されている。なお、突起３は、１つでも良い。また、フック６が形成された突起３は、突起部材を溶接等により後付けによりバンド部１の内面に取り付けても良い。   The protrusion 3 is formed by punching out the band portion 1 by a press and bending a part of the band portion 1 at a right angle inside the band portion 1, and a hook 6 is formed at the tip. The protrusions 3 are formed in a pair on the left and right, and the pair of hooks 6 are formed in the upper and lower directions. The number of projections 3 may be one. Further, the projection 3 on which the hook 6 is formed may be attached to the inner surface of the band portion 1 by retrofitting the projection member by welding or the like.

図３および図４に示すように、横ビーム８が取り付けられる支柱７には、図３に示すように、開口９が形成されている。開口９内に突起３が挿入されることによって、フック６が開口６に係合する。さらに、バンド部１の内径は、支柱７の外径より若干小さく形成されているので、横ビーム取付部２間に横ビーム８を挟んで横ビーム取付ボルト１０を締め付けると、バンド部１は、緩むことなく支柱７を締め付け、支柱７に固定される。この結果、横ビーム取付金具用ボルトを使用することなく、横ビーム取付金具Ｃを支柱７の所定の位置に取り付けることができる。このように、横ビーム取付金具用ボルトを使用する必要がないので、支柱７への横ビーム８の取り付けが容易に行えると共に外観に優れ、しかも、コストの低減を図ることができる。   As shown in FIGS. 3 and 4, the support 7 to which the transverse beam 8 is attached is formed with an opening 9 as shown in FIG. The hooks 6 engage with the openings 6 by inserting the protrusions 3 into the openings 9. Furthermore, since the inner diameter of the band portion 1 is formed to be slightly smaller than the outer diameter of the support column 7, when the horizontal beam mounting bolt 10 is tightened with the horizontal beam 8 interposed between the horizontal beam mounting portions 2, the band portion 1 The support 7 is tightened without being loosened and fixed to the support 7. As a result, the cross beam mounting bracket C can be mounted at a predetermined position of the support 7 without using the cross beam mounting bracket bolt. As described above, since it is not necessary to use a bolt for lateral beam attachment, it is possible to easily attach the lateral beam 8 to the support 7 and also to be excellent in appearance and to reduce the cost.

また、一対のフック６は、上下外向きに形成されているので、突起３が開口９内に挿入されると、横ビーム８の上下左右方向の移動を確実に阻止することができる。   Further, since the pair of hooks 6 are formed in the upper and lower directions, when the projection 3 is inserted into the opening 9, the movement of the horizontal beam 8 in the vertical and horizontal directions can be reliably blocked.

このように構成されている横ビーム取付金具Ｃにより支柱に横ビームを取り付けるには、以下のようにする。   In order to attach a cross beam to a support | pillar by the cross beam attachment bracket C comprised in this way, it is as follows.

図４に示すように、支柱７の左側に横ビーム８を水平に取り付けるには、支柱７に横ビーム取付金具Ｃのバンド部１を嵌め込み、突起３を支柱７に形成された開口９内に挿入する。   As shown in FIG. 4, in order to horizontally attach the horizontal beam 8 to the left side of the support 7, the band portion 1 of the lateral beam mounting bracket C is fitted in the support 7, and the projection 3 is in the opening 9 formed in the support 7. insert.

次いで、横ビーム８の端部を横ビーム取付部２間に水平に挟み込み、横ビーム取付ボルト１０を横ビーム取付部２のボルト孔４と横ビーム８の端部に形成されたボルト孔（図示せず）とに挿入し、ナット１１によって固定する（図５参照）。   Next, the end of the cross beam 8 is horizontally inserted between the cross beam mounting portion 2 and the cross beam mounting bolt 10 is formed in the bolt hole 4 of the cross beam mounting portion 2 and the bolt hole of the cross beam 8 (see FIG. (Not shown) and fixed by a nut 11 (see FIG. 5).

これによって、支柱７の左側に横ビーム８を水平に取り付けることができる。   This allows horizontal beam 8 to be mounted horizontally on the left side of column 7.

次に、図４に示すように、支柱７の右側に横ビーム８を傾斜して取り付けるには、横ビーム取付金具Ｃを上下反転させ、支柱７に形成された開口９に、横ビーム取付金具Ｃのバンド部１を嵌め込む。横ビーム取付金具Ｃを上下反転させて使用することによって、支柱７への横ビーム８の取り付け部分の外観が良くなる。   Next, as shown in FIG. 4, in order to attach the horizontal beam 8 to the right side of the column 7 by tilting it, the horizontal beam mounting bracket C is turned upside down, and the horizontal beam mounting bracket is inserted into the opening 9 formed in the column 7. Fit the C band 1. By using the horizontal beam mounting bracket C upside down, the appearance of the mounting portion of the horizontal beam 8 to the support 7 is improved.

次いで、横ビーム８の端部を横ビーム取付部２間に傾斜させて挟み込み、横ビーム取付ボルト１０を横ビーム取付部２のボルト孔４と横ビーム８の端部に形成されたボルト孔（図示せず）とに挿入し、ナット１１によって固定する（図５参照）。   Then, the end portion of the cross beam 8 is inclined between the cross beam mounting portion 2 and the cross beam mounting bolt 10 is formed in the bolt hole 4 of the cross beam mounting portion 2 and the bolt hole (Not shown) and fixed by a nut 11 (see FIG. 5).

これによって、支柱７の右側に横ビーム８を傾斜して取り付けることができる。   Thereby, the horizontal beam 8 can be attached to the right side of the support 7 in an inclined manner.

次に、横ビーム取付金具Ｃにより横ビーム８を水平面内において角度をつけて支柱７に取り付けるには、横ビーム取付金具Ｃの突起３をハンマー等により平らにした後、支柱７に、横ビーム取付金具Ｃのバンド部１を嵌め込む。   Next, in order to attach the cross beam 8 to the support 7 at an angle in the horizontal plane by the cross beam mounting bracket C, the projection 3 of the cross beam mounting bracket C is flattened with a hammer or the like. Fit the band 1 of the mounting bracket C.

次いで、横ビーム取付金具Ｃを支柱７回りに所定角度だけ回転させ、横ビーム８を横ビーム取付金具Ｃに横ビーム取付ボルト１０により取り付ける。   Next, the cross beam mounting bracket C is rotated about the support 7 by a predetermined angle, and the cross beam 8 is attached to the cross beam mounting bracket C by the cross beam mounting bolt 10.

これによって、図５に示すように、横ビーム８を水平面内において角度をつけて支柱７に取り付けることができる。   This allows the transverse beam 8 to be attached to the post 7 at an angle in the horizontal plane, as shown in FIG.

以上説明したように、この発明によれば、バンド部１に形成された突起３を支柱７に形成した開口９に係合させることによって、横ビーム取付金具用ボルトを使用することなく、支柱７に横ビーム取付金具Ｃを取り付けることができるので、支柱７への横ビーム８の取り付けが容易に行えると共に外観に優れ、しかも、コスト低減を図ることができる。   As described above, according to the present invention, by engaging the projection 3 formed on the band portion 1 with the opening 9 formed on the support 7, the support 7 is used without using the bolt for the horizontal beam mounting bracket. Since the lateral beam attachment bracket C can be attached to the support 7, the lateral beam 8 can be easily attached to the support 7, and the appearance is excellent, and moreover, the cost can be reduced.
