道路端に設置されているガードレールとして図６に示すガードレールがある。 このガードレール41は、適宜間隔をおいて建植された複数本の支柱42にブラケッ ト43を介して長尺板製横桟44を取付けて構成されている。 As a guardrail installed at the road edge, there is a guardrail shown in FIG. The guardrail 41 is configured by attaching a long plate-shaped horizontal rail 44 via a bracket 43 to a plurality of columns 42 which are planted at appropriate intervals.
【０００３】 支柱42は、断面円形の金属管で構成され、上部側面には長尺板製横桟44が取付 けられ、また通常上端には支柱用キャップ45が取付けられている。The column 42 is made of a metal tube having a circular cross section, and a long plate-shaped horizontal bar 44 is attached to the upper side surface, and a column cap 45 is usually attached to the upper end.
【０００４】 ブラケット43は、金属帯板により形成され、図６ｄに示すように、中央部に中 窪み46を、その両端に鍔部47, 48を有する。中窪み46の底部49は支柱42の外周面 に取付けるため円弧に形成され、その中央部には支柱42への取付け用ボルト孔が 開けられている。また、鍔部47, 48には長尺板製横桟44を取付けるための取付け 用ボルト孔が開けられている。[0004] The bracket 43 is formed of a metal strip, and as shown in Fig. 6d, has a central recess 46 at the center and flanges 47 and 48 at both ends. A bottom portion 49 of the hollow 46 is formed in an arc shape to be attached to the outer peripheral surface of the column 42, and a bolt hole for attaching to the column 42 is formed in the center thereof. The flanges 47 and 48 are provided with mounting bolt holes for mounting the horizontal plate 44 made of a long plate.
【０００５】 長尺板製横桟44は、図６ｃに示すように、中央部に溝部50を有し、その溝部50 の上下に表面側に突出して山部51, 52を有する幅方向断面波形形状の長尺な金属 板で構成され、その長手方向の両端の溝部50とその上下部の山部51, 52には取付 け用ボルト孔がそれぞれ開けられている。そして、この取付け用ボルト孔にボル ト・ナット53を取付けて、横桟44の複数枚を長手方向に繋ぎ合わせる。この繋ぎ 合わせの際、繋ぎ合わせ部の背面には横桟44を支柱42に取付けるためのブラケッ ト43が設けられ、それらの取付け用ボルト孔に横桟44の取付け用ボルト孔を重ね 合わせボルト・ナット53により取付けられる。なお、ブラケット43はボルト・ナ ット54により支柱42へ取付けられている。As shown in FIG. 6C, the horizontal bar 44 made of a long plate has a groove 50 in the center, and has a cross section in the width direction having ridges 51 and 52 protruding to the surface above and below the groove 50. It is made of a long metal plate having a long shape, and mounting bolt holes are respectively formed in the grooves 50 at both ends in the longitudinal direction and the ridges 51 and 52 at the upper and lower portions. Then, a bolt / nut 53 is attached to the mounting bolt hole, and a plurality of the horizontal rails 44 are joined in the longitudinal direction. At the time of this joining, a bracket 43 is provided on the back of the joining portion for attaching the horizontal rail 44 to the support column 42, and the mounting bolt holes of the horizontal rail 44 are overlapped with the bolt holes for mounting.

【０００６】[0006]
上記構成のガードレール41において、長尺板製横桟44を順次長手方向に繋ぎ合 わせながら支柱42に取付けて施工されるが、既設の長尺板製横桟44に長尺板製横 桟44を重ねて繋ぎ合わせるには、既設の長尺板製横桟44の未施工の端に繋ぎ合わ せる側の長尺板製横桟44の一方の端を重ねるとともに、前記重ね部の支柱42への 取付け用ボルト孔を合わせつつ、繋ぎ合わせる側の長尺板製横桟44を道路と平行 に保持しておく必要があり、その保持を人手によって行ってきた。そして、これ までは、標準寸法（幅 350mm×長さ約4000mm×厚さ 4.0mm×重さ約65kg) の長尺 板製横桟44であれば、人手で保持するにしても重量的に特別な問題もなく道路と 平行に保持して施工がなされてきたが、これまで以上に強度が要求されるような ことになり重量が嵩むようになると、人手による保持が難しくなり、また人手で 保持できたとしても、重ね部の支柱42に取付けられたブラケット43への取付けボ ルト孔の合わせが難しくなったり、今まででも同じことではあるが滑り落とす危 険がある。 In the guardrail 41 having the above structure, the long rails 44 are attached to the columns 42 while sequentially connecting the long rails 44 in the longitudinal direction, and the long rails 44 are attached to the existing long rails 44. In order to overlap and join together, one end of the long plate horizontal bar 44 to be joined to the unconstructed end of the existing long plate horizontal bar 44 is overlapped, and It is necessary to hold the side plate 44 made of the long plate to be joined in parallel with the road while aligning the mounting bolt holes, and the holding has been performed manually. Until now, if the long board made of long boards 44 with standard dimensions (350 mm in width × about 4000 mm in length × 4.0 mm in thickness × about 65 kg in weight), even if it is held manually, it will be special in weight. The construction has been carried out parallel to the road without any problems.However, if the strength is required more than before and the weight increases, it becomes difficult to hold it by hand, and it can be held manually. Even so, there is a risk that it is difficult to align the mounting bolt holes with the bracket 43 mounted on the pillar 42 of the overlapping portion, and there is a risk of slipping down as in the past.
【０００７】 本考案は、上記の事情に鑑みてなされたものであって、その目的は、横桟を繋 ぎ合わせて支柱へ取付ける際の施工を容易に且つ安全に行い得るガードレールを 提供するものである。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a guardrail that can easily and safely perform construction when connecting horizontal rails to a support post. It is.
