A screw hole 11 is provided in the wall of the support column 1, and the bottom plate portion 32 is fastened to the support column 1 by screwing the screw 4 into the screw hole 11 through the through hole 33. Thus, the mounting bracket 3 can be attached to one or both sides of the column 1. In the present invention, in addition to attaching the mounting bracket 3 to the column 1 by tightening screws as in the above example, bolts are used instead of the screws 4, and the mounting bracket 3 is attached to the column 1.
The bottom plate portion 32 of the mounting bracket 3 is brought into contact with both sides of the mounting bracket 3, and the bolts are
2 to the column 1, and then to the bottom plate 32 of the other mounting bracket 3, and by screwing nuts into the bolts, the bottom plate 32 is fastened to the column 1.

防護柵が構成される。 Furthermore, the cylindrical part 31 of the mounting bracket 3 is divided into two parts parallel to the cylinder axis into an upper part 311 and a lower part 312, and a through hole 3 having a countersunk part in the wall of the lower part 312.
4, and the corresponding wall of the upper part 311 is formed with a protruding wall 36 having a screw hole 35 extending into the wall. Also, one end of the horizontal bar 2 is inserted into the cylindrical portion 31 of the mounting bracket 3, one of the through holes 21 and 22 in the diametrical direction of the horizontal bar 2 is fitted into the protruding wall 36, and the screw 5 passes through the through holes 21 and 22 of the horizontal bar 2 from the through hole 34, and is screwed into the screw hole 35. The head of the screw 5 is located in the countersunk portion of the through hole 34, and is flush with the wall surface of the cylindrical portion 31 of the mounting bracket 3 or recessed into the wall. In this way, the horizontal bar 2 is attached to the mounting bracket 2, and the protective fence of the present invention is constructed.

付作業が容易となり好ましい。 In addition, in the present invention, the through hole 2 of the horizontal bar 2
1 and 22 are conveniently formed into elongated holes so that the horizontal bar 2 can be adjusted to the left and right during installation. In addition, when forming the protruding wall 36 on the cylindrical portion 31 of the mounting bracket 3, the mounting bracket 2 is manufactured by casting, and a stepped portion 37 is formed on the mating surface of the upper part 311 and lower part 312, which are divided into two parts. It is preferable that the step portions 37 are fitted into each other because the upper portion 311 and the lower portion 312 are difficult to displace, and the installation work of the horizontal bar 2 is facilitated.
上述の如く、本考案の防護柵は、支柱に横棒を

横棒は支柱と交差することがなく、直線性が損わ
れず、見栄えのよい防護柵が得られる。 As mentioned above, the protective fence of the present invention has a horizontal bar connected to a support using a mounting bracket, and the mounting bracket consists of a cylindrical portion and a bottom plate portion formed at one end of the cylindrical portion. The bottom plate part is brought into contact with the surface of the column, and is fastened to the column with bolts or screws, and one end of the horizontal bar is inserted into the cylindrical part, and the horizontal bar is penetrated from one wall of the cylindrical part. The horizontal bar is attached and fixed to the mounting bracket by screws screwed into the other wall. Therefore, the ends of the horizontal bars are not exposed, preventing rust from forming at the ends of the horizontal bars, and furthermore, the horizontal bars do not intersect with the pillars, so straightness is not impaired, providing good-looking protection. You get a fence.
さらに、本考案においては取付金具の筒状部分
が上部と下部との二つ割りとなされ、下部の壁か
ら上部の突出壁中のネジ孔へネジが捩じ込まれて
いるので、横棒が上部と下部とでしつかり挟み付
けられ、取付金具と横棒とが強固に結合されると
共にネジの先が直接突出壁のネジ孔に捩じ込まれ
ナツトが不要となり捩じ込み作業が容易である。 Furthermore, in this invention, the cylindrical part of the mounting bracket is divided into two parts, an upper part and a lower part, and the screw is screwed from the lower wall into the screw hole in the upper protruding wall, so that the horizontal bar is connected to the upper part. It is firmly clamped between the lower part and the mounting bracket and the horizontal bar are firmly connected, and the tip of the screw is directly screwed into the screw hole of the protruding wall, eliminating the need for a nut and making the screwing operation easy.
さらにまた、本考案においては上部内方に形成
された突出壁に横棒の貫通孔が嵌め込まれている
ので、防護柵の使用中に該横棒に外力がかかつて
引張られても該引張力は突出壁にかかつて直接ネ

り、美感が向上する。 Furthermore, in the present invention, the screws fixing the mounting bracket and the horizontal bar have screw heads that are flush with the wall surface at the bottom of the mounting bracket or recessed into the wall, and do not protrude into the bottom surface. The tip of the fence is simply screwed into a screw hole in the protruding wall inside the top, and does not penetrate outward from the top, so even if a pedestrian touches the protective fence, it will not be damaged by the screw, making it extremely safe. Moreover, the screws are almost invisible and the area around the pillars is clean, improving the aesthetic appearance.
