Description

本発明は、防音パネルの取付金具及び防音構造に関するものである。   The present invention relates to a mounting bracket and a soundproof structure for a soundproof panel.

従来、道路に沿って防音パネルを設置することにより、道路を走行する車によって発生する騒音が道路外に漏れるのを低減することが行われている。下記の特許文献１には、道路に沿って所定間隔で立設された支柱間に防音パネルを配設するとともに、各支柱に防音パネルの幅方向の端部を取り付けた防音構造が示されている。   Conventionally, by installing a soundproof panel along a road, it has been practiced to reduce leakage of noise generated by a vehicle traveling on the road to the outside of the road. The following Patent Document 1 shows a soundproof structure in which soundproof panels are arranged between pillars erected at predetermined intervals along a road, and ends in the width direction of the soundproof panels are attached to the pillars. Yes.

特許文献１に開示された防音構造では、道路に沿ってＨ形鋼からなる複数の支柱が所定間隔で立設されており、隣り合う支柱の各溝部が道路に平行な方向において互いに対向するように配置されている。防音パネルは、隣り合う支柱間に配設され、その防音パネルの幅方向の両端部が対応する支柱の溝部にそれぞれ嵌め込まれている。その防音パネルの端部の道路と反対側の面と対向する前記溝部の内面との間の隙間には固定金具が嵌め込まれており、この固定金具によって防音パネルの端部が支柱に対して固定されている。

ところで、防音パネルを道路脇に設置する際、隣り合う支柱間に複数段の防音パネルを高さ方向に並べて設置する場合がある。この場合において、上記特許文献１の防音構造における防音パネルの支柱への取付方法を用いると、下段の防音パネルの交換作業が煩雑になるという問題点がある。   By the way, when installing a soundproof panel on the side of a road, a plurality of soundproof panels may be arranged side by side in the height direction between adjacent columns. In this case, if the method of attaching the soundproof panel to the support in the soundproof structure of Patent Document 1 is used, there is a problem that the work for replacing the lower soundproof panel becomes complicated.

すなわち、上記特許文献１の防音構造では、防音パネルの両端部が隣り合う支柱の各溝部にそれぞれ嵌り込んでいるため、複数段の防音パネルのうち下段の防音パネルのみ交換が必要な場合でも、上段の防音パネルを上方に抜き出してから下段の防音パネルを上方に抜き出して交換し、その後、上段の防音パネルを上方から支柱間に挿し込み直すという煩雑な作業が必要となる。   That is, in the soundproof structure of the above-mentioned Patent Document 1, since both ends of the soundproof panel are respectively fitted in the respective groove portions of the adjacent columns, even if only the lower soundproof panel of the plurality of soundproof panels needs to be replaced, After the upper soundproof panel is pulled out upward, the lower soundproof panel is pulled out and replaced, and then the upper soundproof panel is inserted again between the columns from above.

このような煩雑な防音パネルの挿抜作業を回避するために、支柱に挿通孔を形成するとともにその挿通孔に挿通したボルトと取付金具を利用して支柱の溝部に防音パネルの端部が嵌り込まない状態でその支柱に各段の防音パネルの端部を固定することも考えられる。   In order to avoid such complicated soundproofing panel insertion / extraction work, the end of the soundproofing panel is fitted into the groove of the column using the bolts and mounting brackets that are inserted into the column and the insertion hole is formed in the column. It is also conceivable to fix the end of the soundproof panel at each stage to the column in the absence.

しかしながら、現場での支柱に対する挿通孔の孔開け作業は煩雑であるため、そのような作業はなるべく回避することが望まれる。   However, since the operation of drilling the insertion hole for the support on the site is complicated, it is desired to avoid such work as much as possible.

この発明は、上記の課題を解決するためになされたものであり、その目的は、隣り合う支柱間に複数段の防音パネルが高さ方向に並べて設置される場合でも、下段の防音パネルの交換作業及び防音パネルの支柱への取付作業を簡略化することが可能な防音パネルの取付金具及び防音構造を提供することである。   The present invention has been made in order to solve the above-described problem, and its purpose is to replace a lower soundproof panel even when a plurality of soundproof panels are installed side by side between adjacent columns. It is an object to provide a soundproof panel mounting bracket and a soundproof structure capable of simplifying the work and the work of mounting the soundproof panel to a support.

上記目的を達成するために、本発明による防音パネルの取付金具は、道路に沿って所定間隔で立設され、前記道路に対して略垂直に配置される隔壁部と、前記道路に対して略平行に配置されるとともに前記隔壁部の前記道路側の端部に繋がってその隔壁部の両側に延びる支持部とを有する支柱に対してその両側に防音パネルをそれぞれ取り付けるための防音パネルの取付金具であって、前記支持部に対して前記道路側から被せられる第１金具と、前記第１金具に裏側からあてがわれ、前記支持部のうち前記隔壁部の両側に延びる部分をそれぞれ前記第１金具との間で挟み込む一対の第２金具と、前記各第２金具と前記第１金具とを前記道路側から締結するための締結具とを備え、前記第１金具は、前記支持部の前記道路側の面を覆う覆部と、その覆部の幅方向の両端部からそれぞれ前記道路の幅方向外側へ延びる一対の延設部と、その各延設部の前記覆部と反対側の端部からそれぞれ前記支持部の幅方向外側に延びるとともに対応する前記防音パネルの端部が固定される一対の固定部とを含み、前記各第２金具は、前記固定部の裏側に重なるとともにその固定部に前記締結具によって締結される締結部と、その締結部の前記隔壁部側の端部から前記道路側に延び、前記締結具による前記固定部と前記締結部との締結に伴って前記覆部の裏面との間で前記支持部を挟持する形状を有する挟持部とをそれぞれ含む。   In order to achieve the above object, a mounting bracket for a soundproof panel according to the present invention is provided with a partition wall portion that is erected at a predetermined interval along a road and is disposed substantially perpendicularly to the road, and is substantially parallel to the road.
