上述した従来取付金具Ａによれば、受け金具２３に横ビーム２２を仮置きすることができるので、支柱２１への横ビーム２２の取り付けが容易に行えるが、受け金具取付ボルト２７が不可欠であるので、外観が悪いと共に、材料費がかかる。   According to the above-described conventional mounting bracket A, the horizontal beam 22 can be temporarily placed on the receiving bracket 23. Therefore, the mounting of the lateral beam 22 to the support column 21 can be easily performed, but the receiving bracket mounting bolt 27 is indispensable. Therefore, the appearance is bad and material costs are required.

上述した従来取付金具Ｂによれば、固定ボルト４１が露出しないので、外観は、優れているが、固定ボルト４１が不可欠であるので、材料費がかかる。しかも、固定ボルト４１の締結作業がやりづらいので、支柱３７への横ビーム４０の取り付けに時間を要する。   According to the above-described conventional mounting bracket B, the fixing bolt 41 is not exposed, and thus the appearance is excellent, but the fixing bolt 41 is indispensable, so that the material cost is increased. Moreover, since it is difficult to fasten the fixing bolt 41, it takes time to attach the lateral beam 40 to the support column 37.

従って、この発明の目的は、横ビームの仮置きができるので、支柱への横ビームの取り付けが容易に行え、しかも、支柱に横ビーム取付金具を固定する横ビーム取付金具用固定ボルトが不要であるので、この点からも支柱への横ビームの取り付けが容易に行えると共に、外観に優れ、さらに、コスト低減を図ることができる防護柵用横ビーム取付金具を提供することにある。   Therefore, the object of the present invention is that the horizontal beam can be temporarily placed, so that the horizontal beam can be easily attached to the column, and the fixing bolt for the horizontal beam mounting bracket for fixing the horizontal beam mounting bracket to the column is unnecessary. Therefore, also from this point, it is an object to provide a horizontal beam mounting bracket for a protective fence that can easily attach a horizontal beam to a support column, has an excellent appearance, and can reduce costs.

FIG. 3 is a side view showing a state in which a horizontal beam is attached to the column by the protective fence horizontal beam mounting bracket of the present invention, and FIG. 4 is a column of the protective fence horizontal beam mounting bracket of the present invention. It is a perspective view which shows the state which attached the horizontal beam to.

図１から図４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、上下対称の一対の横ビーム取付金具本体１ａ、１ｂからなっている。横ビーム取付金具本体１ａ、１ｂは、一端に横ビーム３に取り付けられる丸パイプからなる支柱２との当接面４を有する管体を半割にした形状を有している。横ビーム３の外径は、横ビーム３を支柱２に仮止めされた横ビーム取付金具本体１ａ、１ｂ間に挟み込んだときに、横ビーム取付金具本体１ａ、１ｂ間の間隔（Ｌ）（図２、図３参照）が広がる寸法を有している。   As shown in FIGS. 1 to 4, the horizontal beam mounting bracket C (hereinafter simply referred to as a horizontal beam mounting bracket C) for a guard fence according to the present invention comprises a pair of vertically symmetric horizontal beam mounting bracket bodies 1a and 1b. It has become. Each of the transverse beam mounting metal bodies 1a and 1b has a shape in which a tubular body having a contact surface 4 with a support 2 made of a round pipe attached to the transverse beam 3 at one end is halved. The outer diameter of the transverse beam 3 is the distance (L) between the transverse beam mounting bracket bodies 1a and 1b when the transverse beam 3 is sandwiched between the transverse beam mounting bracket bodies 1a and 1b temporarily fixed to the support column 2 (see FIG. 2 (see FIG. 3).

当接面４は、横ビーム取付金具本体１ａ、１ｂの一端を閉鎖するように形成されているとともに、支柱２が丸パイプからなっているので、凹面状に形成されている。支柱２が角パイプからなる場合には、当接面４は、平面状とする。 The contact surface 4 is formed so as to close one end of the transverse beam mounting metal bodies 1a and 1b, and is formed in a concave shape because the support column 2 is made of a round pipe. When the support column 2 is formed of a square pipe, the contact surface 4 is planar.

上部の横ビーム取付金具本体１ａの上面には、横ビーム３を横ビーム取付金具本体１ａ、１ｂに取り付ける横ビーム取付ボルト５が挿通されるボルト孔６が形成され、下部の横ビーム取付金具本体１ｂの下面には、横ビーム取付ボルト５が挿通されるボルト孔７が形成されている。   A bolt hole 6 is formed on the upper surface of the upper horizontal beam mounting bracket main body 1a, through which a horizontal beam mounting bolt 5 for mounting the horizontal beam 3 to the horizontal beam mounting bracket main bodies 1a and 1b is inserted. Bolt holes 7 through which the transverse beam mounting bolts 5 are inserted are formed on the lower surface of 1b.

上部の横ビーム取付金具本体１ａの当接面４には、支柱２に形成された開口８に係合する、先端が上方に折れ曲がった突起９ａが形成されている。下部の横ビーム取付金具本体１ｂの当接面４には、支柱２に形成された開口８に係合する、先端が下方に折れ曲がった突起９ｂが形成されている。また、突起９ａ、９ｂは、横ビーム取付金具本体１ａ、１ｂを互いに当接させた（合わせた）ときに、その先端の間隔が支柱２に形成された開口８よりも若干小さく（−１から−２ｍｍ）なるように形成されている。従って、突起９の先端が支柱２に形成された開口８に挿入されると、突起９ａ、９ｂの先端が開口８に係合するので、従来取付金具ＡおよびＢのように、これらを支柱に固定する固定ボルトが不要となる。   A protrusion 9 a whose tip is bent upward is formed on the contact surface 4 of the upper horizontal beam mounting bracket main body 1 a so as to engage with the opening 8 formed in the column 2. A protrusion 9b whose tip is bent downward is formed on the contact surface 4 of the lower horizontal beam mounting bracket main body 1b to engage with the opening 8 formed in the support column 2. Further, the protrusions 9a and 9b are slightly smaller than the opening 8 formed in the support column 2 when the horizontal beam mounting bracket main bodies 1a and 1b are brought into contact (matched) with each other (from −1). -2 mm). Accordingly, when the tips of the projections 9 are inserted into the openings 8 formed in the support columns 2, the tips of the projections 9a and 9b engage with the openings 8. Therefore, like the conventional mounting brackets A and B, these are used as support columns. Fixing bolts for fixing are unnecessary.

横ビーム取付金具Ｃにより、支柱２に横ビーム３を取り付けるには、以下のようにする。   In order to attach the transverse beam 3 to the column 2 by the transverse beam mounting bracket C, the following is performed.

図５（ａ）に示すように、先ず、下部の横ビーム取付金具本体１ｂの突起９ｂを支柱２に形成された開口８に挿入して、下部の横ビーム取付金具本体１ｂを支柱２に仮止めする。この際、当接面４が支柱２に当接することと、突起９ｂの先端が下方に折れ曲がっていることにより、突起９ｂは、開口８に係合して、下部の横ビーム取付金具本体１ｂは、支柱２から外れることはない。   As shown in FIG. 5A, first, the projection 9b of the lower horizontal beam mounting bracket main body 1b is inserted into the opening 8 formed in the column 2, and the lower horizontal beam mounting bracket main body 1b is temporarily mounted on the column 2. Stop. At this time, the abutment surface 4 abuts on the support column 2 and the tip of the projection 9b is bent downward, so that the projection 9b engages with the opening 8 and the lower horizontal beam mounting bracket main body 1b is , It will not come off the support 2.

次いで、図５（ｂ）に示すように、横ビーム３の端部を下部の横ビーム取付金具本体１ｂに仮置きする。このようにして、横ビーム３を仮置きしたら、同図に示すように、上部の横ビーム取付金具本体１ａの突起９ａを支柱２に形成された開口８に挿入する。そして、図５（ｃ）に示すように、横ビーム取付金具本体１ａ、１ｂ間に横ビーム３を挟み込む。この際、横ビーム３の外径は、横ビーム３を横ビーム取付金具本体１ａ、１ｂ間に挟み込んだときに、横ビーム取付金具本体１ａ、１ｂ間の間隔（Ｌ）が広がる寸法を有しているので、突起９ａ、９ｂの間隔（Ｌ）も略上下方向に広がり、突起９ａ、９ｂの折れ曲がった先端が支柱２の開口８にがたつくことなく係合する。この結果、横ビーム取付金具本体１ａ、１ｂは、支柱２に強固に固定される。   Next, as shown in FIG. 5B, the end of the horizontal beam 3 is temporarily placed on the lower horizontal beam mounting bracket main body 1b. When the transverse beam 3 is temporarily placed in this way, the projection 9a of the upper transverse beam mounting bracket main body 1a is inserted into the opening 8 formed in the support column 2 as shown in FIG. And as shown in FIG.5 (c), the horizontal beam 3 is inserted | pinched between the horizontal beam attachment bracket main bodies 1a and 1b. At this time, the outer diameter of the transverse beam 3 is such that when the transverse beam 3 is sandwiched between the transverse beam mounting bracket main bodies 1a and 1b, the interval (L) between the transverse beam mounting bracket main bodies 1a and 1b is widened. Therefore, the interval (L) between the protrusions 9a and 9b also extends substantially in the vertical direction, and the bent ends of the protrusions 9a and 9b engage with the opening 8 of the column 2 without rattling. As a result, the transverse beam mounting bracket main bodies 1 a and 1 b are firmly fixed to the support column 2.

次いで、横ビーム取付ボルト５を横ビーム取付金具本体１ａ、１ｂのボルト孔６、７および横ビーム３のボルト孔１０に挿通してナット１１により固定する。   Next, the horizontal beam mounting bolt 5 is inserted into the bolt holes 6 and 7 of the horizontal beam mounting bracket main bodies 1 a and 1 b and the bolt hole 10 of the horizontal beam 3 and fixed by the nut 11.

以上のようにして、横ビーム取付金具Ｃにより、支柱２に横ビーム３を取り付けることができる。   As described above, the transverse beam 3 can be attached to the support column 2 by the transverse beam mounting bracket C.

以上、説明したように、この発明によれば、横ビーム取付金具本体１ａ、１ｂを突起９ａ、９ｂのみを介して支柱２に取り付けることができ、しかも、横ビーム３を下部の横ビーム取付金具本体１ｂに仮置きすることができるので、支柱２への横ビーム３の取り付けが容易に行えると共に、横ビーム取付金具本体１ａ、１ｂを支柱２に固定する固定ボルトが不要となるので、外観に優れ、しかも、コストの低減を図ることができる。   As described above, according to the present invention, the horizontal beam mounting bracket main bodies 1a and 1b can be mounted on the support column 2 only through the projections 9a and 9b, and the horizontal beam 3 can be mounted on the lower horizontal beam mounting bracket. Since it can be temporarily placed on the main body 1b, the horizontal beam 3 can be easily attached to the support column 2, and the fixing bolt for fixing the horizontal beam mounting bracket main bodies 1a, 1b to the support column 2 is not required. It is excellent and the cost can be reduced.
