Abstract

【課題】本考案はガードレールのボルト部に接触、衝突などを起した車輌等の車体の一部が引掛かり、残ることをビーム表面に凸形状を設ける事により防止する。
【解決手段】本考案はビーム表面の取付ボルト周りに凸形状を成型し、ボルトとビーム表面の隙間を１の様に埋没させ車輌等の車体の引っ掛かりを起こし難くすることによりガードレールの機能の安全性を高める事に役立つ。
【選択図】図２The present invention prevents a part of a vehicle body such as a vehicle that has contacted or collided with a bolt portion of a guardrail from being caught and left by providing a convex shape on a beam surface.
The present invention forms a convex shape around the mounting bolt on the beam surface, and embeds the gap between the bolt and the beam surface like 1 to make it difficult to catch the vehicle body such as a vehicle. Helps to improve sex.

Description

本考案はガードレールのビーム表面（袖ビームも含め、以下ビームと呼ぶ）の取付ボルト周りに凸形状を成型したビームに関するものである。The present invention relates to a beam obtained by forming a convex shape around a mounting bolt on a beam surface of a guardrail (including a sleeve beam, hereinafter referred to as a beam).

技術の背景Technology background

ガードレールに接触、衝突した車輌等の車体の一部がビーム表面と取付ボルトの隙間に引掛かり、剥ぎ取られて危険性のある金属片等が残ることが有るため。Part of the vehicle body, such as a vehicle that has contacted or collided with the guardrail, is caught in the gap between the beam surface and the mounting bolt, and may be stripped off, leaving a dangerous metal piece.

ビーム表面とボルトの隙間に車体の一部の金属片等が残り、通行人等に危険を及ぼす事を解決しようとするものである。It is intended to solve the problem that a part of the metal piece of the vehicle body remains in the gap between the beam surface and the bolt, causing danger to passers-by.

問題を解決するための手段Means to solve the problem

本考案はガードレール部材の取付ボルト周りのビーム表面を凸形状に成型する事により、ボルトとビームの継ぎ目を埋没させ車輌等の接触、衝突による車体等の一部が引掛かり、残置する問題点を解決している。In the present invention, the beam surface around the mounting bolt of the guardrail member is formed into a convex shape, so that the joint between the bolt and the beam is buried, and a part of the vehicle body etc. is caught and left behind by contact with the vehicle, etc. It has been solved.

考案の効果Effect of device

上述の形状をビームに成型することにより従来は考慮されていなかった金属片等の残置対策が施されることとなりガードレールに対する安全性がいっそう高まる事になり役立つ。By forming the above-mentioned shape into a beam, it is possible to take measures against leaving a metal piece or the like, which has not been considered in the past, and the safety for the guardrail is further enhanced.

ガードレールのビーム面に成型する凸形状はボルト頭部方向へ滑らかな線形で変化すること。凸形状の高さはビームとボルト接触部を必ず越える高さであるとともに取付ボルトの高さを越えないこと。また凸形状の外縁はビームの形状断面の凹凸の各幅内をなるべく侵さない範囲内にとどめる。ボルトの外縁と凸部の内縁立上りの間隔は出来るだけ狭くする。The convex shape to be molded on the beam surface of the guardrail should change smoothly and linearly toward the bolt head. The height of the convex shape must be higher than the beam and bolt contact area, and must not exceed the height of the mounting bolt. Further, the outer edge of the convex shape is kept within a range that does not erode as much as possible within each width of the unevenness of the cross section of the beam shape. The distance between the outer edge of the bolt and the rise of the inner edge of the projection is as narrow as possible.
