Description
【0001】
【発明の属する技術分野】
本発明は、跨線橋、跨道橋又は高架橋の側面に立設して、除雪時の飛雪や車窓からの落下物の飛散を防止する柵に関するものである。
【0002】
【従来の技術】
従来の上記飛雪等の防止柵は、金網やエキスパンドメタルを張設して橋梁の側縁に沿って設けているのである。
そして、その張設方法は、図6に示すように橋梁に沿って一定間隔に立設した支柱に取り着けているのである。
【0003】
すなわち、金網やエキスパンドメタル11は独自で緊張状態を維持し、かつ支柱12等への取り着けが容易でないため、周囲を枠縁17で固定し、又は必要によっては中間枠13を縦横に補充し、更に両側枠縁に延設した取付用パネル14と支柱12の取付用ブラケット15をボルトナット16で締結することで張設しているのである。
【0004】
【発明が解決しようとする課題】
本発明に係る柵の目的から空間を仕切って飛雪や落下物の飛散を防止する遮蔽性が必要であるけれども、橋梁物に設置するものであるから強度があって、かつ軽量であることが望ましく、更に橋梁からの飛散を防止するに止まらず、透視性があると共に橋梁内への風雪等を減殺防止できれば好都合である。
【0005】
しかし、従来の柵においては枠縁や中間枠が必要であり、又面が風雪等の圧力に耐えるため分厚い強度のある材料を選ばずを得ず、全体の重量が増大し、コストにも影響を及ぼすのである。
【0006】
そこで、本発明は強度があって軽量で、遮蔽性、透視性を有し、更に橋梁内への風雪の侵入を減殺することのできる橋梁の飛雪等防止柵を提供せんとするものである。
【0007】
【課題を解決するための手段】
本発明は、跨線橋、跨道橋又は高架橋の側面に設置する柵であって、橋梁の側縁外側面に定間隔で固定したベースプレートに、支持腕と補助腕を橋梁の外側へ突設し、支持腕と補助腕の先端部に支柱を立設し、橋梁の側縁に沿って一定の間隔で立設した支柱間に有孔折板を横設したことを特徴とするものであり、有孔折板の少なくとも傾斜面の孔を縦長の楕円孔としてもよい。
【0008】
本発明の支柱間に横設する有孔折板は板体であるから、従来のものに比べ強度があり、かつ折曲してあるから板厚も薄くでき、更に孔を穿ってあるから一層の軽量化を図れ、安定して支持できるものである。
【0009】
又、孔を有するため透視性が確保でき、折板であるから風雪の侵入を減殺する作用は周知の通りであり、除雪等によって固まった雪は有孔板であっても受け止めることができるものである。
【0010】
更に、傾斜面の孔を縦長の楕円孔とすることで軽量化、透視性を良好とすると共に、風雪の遮蔽性も充分に確保できるものとなる。
【0011】
【発明の実施の形態】
次に、本発明の実施の形態を図面に基づいて説明する。
図1は本発明の一実施の形態を示す正面図であり、跨線橋、跨道橋又は高架橋の側縁1にアンカーボルト2、2…でベースプレート3を定間隔で固定し、各ベースプレート3に支持腕4と補助腕5の基部を固定して側縁1に突設し、支持腕4と補助腕5の先端に支柱6の下部を固定支持し、支柱6、6…を側縁1に沿って定間隔で立設したものである。
【0012】
支柱6の両側には有孔折板8の取付用プレート7、7を有し、有孔折板8の両側に設けられた取付長孔とを利用してボルトを挿通してナットで締着し、支柱6、6間に有孔折板8を横設している。
【0013】
有孔折板8は上下方向へ垂直面である谷面8Aと山面8Bとの連継面を傾斜面8Cに形成して折曲し、各面に透孔10を穿ったものであり、両側端部の谷面8Aに前記取付長孔を設けたものである。
透孔の形状は任意形状を選択すればよいけれど、縦長楕円孔10Aとすれば透視性を良好とし、遮蔽性も損なうこともない。
【0014】
又、支柱6を橋梁側へ傾斜させて立設して有孔折板8を横設してもよく(図4)、又支柱6の上部を橋梁側へ傾けたものとしてもよい(図5)。
【0015】
【発明の効果】
以上のように、本発明は跨線橋、跨道橋や高架橋の飛雪等防止柵の遮蔽面を有孔折板で形成することによって、強度が充分に得られて軽量化を図るこてができ、遮蔽性、透視性に優れ、しかも風雪の橋梁内への侵入を減殺できる効果をも発揮するものである。

BACKGROUND OF THE INVENTION
The present invention relates to a fence that is erected on the side of an overpass, overpass, or viaduct to prevent snowfall during snow removal and scattering of fallen objects from vehicle windows.
[0002]
[Prior art]
The conventional fences for preventing snow and the like are provided along the side edges of the bridge with a wire mesh or expanded metal stretched.
And the tensioning method is attached to the support | pillar which stood up at fixed intervals along the bridge as shown in FIG.
[0003]
That is, the wire mesh and the expanded metal 11 maintain a tension state by themselves and are not easily attached to the support column 12 or the like, so the periphery is fixed with the frame edge 17 or, if necessary, the intermediate frame 13 is replenished vertically and horizontally. Further, the mounting panel 14 and the mounting bracket 15 of the support column 12 extended to both side frame edges are fastened by fastening with bolts and nuts 16.
[0004]
[Problems to be solved by the invention]
For the purpose of the fence according to the present invention, it is necessary to have a shielding property for partitioning the space to prevent flying snow and falling objects, but since it is installed on a bridge object, it must be strong and lightweight. Desirably, it is not limited to preventing scattering from the bridge, and it is advantageous if it is transparent and can prevent wind and snow from entering the bridge.
[0005]
However, the conventional fence requires a frame edge and an intermediate frame, and because the surface can withstand pressures such as wind and snow, it is not possible to choose a material with thick strength, which increases the overall weight and affects the cost. It affects.
[0006]
Accordingly, the present invention is intended to provide a fence for preventing snow from flying on a bridge that is strong and lightweight, has shielding properties and transparency, and can reduce the intrusion of wind and snow into the bridge. .
[0007]
[Means for Solving the Problems]
The present invention is a fence to be installed on the side of a bridge, overpass or viaduct, and a support plate and an auxiliary arm are projected to the outside of the bridge on a base plate fixed at regular intervals on the outer side surface of the bridge, A strut is erected at the tip of the support arm and auxiliary arm, and a perforated folded plate is installed between the struts erected at regular intervals along the side edge of the bridge. The hole on at least the inclined surface of the hole folded plate may be a vertically long elliptical hole.
[0008]
Since the perforated folded plate installed horizontally between the columns of the present invention is a plate body, it is stronger than the conventional one, and since it is bent, the plate thickness can be reduced, and further, a hole is drilled. Can be reduced in weight and can be supported stably.
[0009]
In addition, since it has holes, it can ensure transparency, and since it is a folded plate, the action of reducing the invasion of wind and snow is well known, and snow solidified by snow removal etc. can be received even if it is a perforated plate It is.
[0010]
Furthermore, by making the hole on the inclined surface into a vertically long elliptical hole, the weight and transparency can be improved, and wind and snow shielding properties can be sufficiently secured.
[0011]

【The invention's effect】
As described above, the present invention can achieve sufficient strength and light weight by forming the shielding surface of the prevention fence such as the overpass, the overpass and the flyover snow with the perforated folded plate. In addition, it has excellent shielding properties and transparency, and also exhibits the effect of reducing the penetration of wind and snow into the bridge.
