Description

本発明は樹脂製ガードレールに関し、特に実質的にハニカム断面を有する樹脂製ガードプレートを有するため、原料を節約でき、金属製ガードレールと比べて遜色ない強度を有し、材料特性やハニカム構造による弾性により車が衝突した際のドライバーへの衝撃を最大限抑えることができ、蛍光物質の混入によりガードプレートが夜間に発光し、夜間運転でのドライバーの視覚を確保することができるガードレールに関する。   The present invention relates to a resin guard rail, and in particular, since it has a resin guard plate having a substantially honeycomb cross section, it can save raw materials, has a strength comparable to a metal guard rail, and has material properties and elasticity due to the honeycomb structure. The present invention relates to a guardrail that can minimize the impact on a driver when a car collides, and that a guard plate emits light at night due to mixing of a fluorescent material, and can ensure the driver's vision during night driving.

一般に、ガードレールは、車が道路から飛び出すのを防ぐため、又は道路の境界線を示すために道路の路肩又は中央に設けられる。ガードレールは、車が衝突したときに衝撃を吸収するとともに、車が道路から飛び出すのを防ぐのに十分な強度を有することが要求される。   In general, guardrails are provided on the shoulders or in the center of the road to prevent cars from jumping off the road or to indicate road boundaries. The guardrail is required to have sufficient strength to absorb the impact when the vehicle collides and to prevent the vehicle from jumping off the road.

しかしながら、従来のガードレールは、図１に示すように、金属製ガードプレート２がガードレールポスト１に結合され、衝撃吸収手段が付加されていない単純構造を有するので、ガードレールに衝突した車に強い衝撃が加わり、人に甚大なダメージを与えてしまう。   However, the conventional guard rail has a simple structure in which the metal guard plate 2 is coupled to the guard rail post 1 and no shock absorbing means is added, as shown in FIG. Join and cause devastating damage to people.

また従来のガードレールのガードプレートは金属製なので、屋外での長時間の使用により腐食し、適宜交換しなければならないので、維持費用が高い。その上、金属製ガードプレートは、補強又は所定の弾性率の確保のために波形にプレスするので、製造工程が増え、コストが増大する。   Moreover, since the guard plate of the conventional guard rail is made of metal, it is corroded by long-term use outdoors and must be replaced as appropriate, so that the maintenance cost is high. In addition, the metal guard plate is pressed into a corrugated shape to reinforce or secure a predetermined elastic modulus, which increases the manufacturing process and costs.

加えて、上記ガードレールは夜間には見えないので、車が衝突する事故が頻発する。最近ではそのような事故を防ぐために、車のヘッドランプからの光を反射する反射体をガードレールに設けているが、それには追加の費用が掛かる。   In addition, since the guardrail is not visible at night, accidents in which vehicles collide frequently occur. Recently, in order to prevent such an accident, a reflector for reflecting light from a car headlamp is provided on the guardrail, but this requires additional cost.

本発明は、従来技術の前述した問題を解決するために想到されたものである。本発明の主な目的は、ガードレールのガードプレートを樹脂の押出しだけで追加工程なしに波形に量産できる低コストの樹脂製ガードレールを提供することである。   The present invention has been conceived to solve the above-described problems of the prior art. A main object of the present invention is to provide a low-cost resin guard rail that can mass-produce a guard plate of a guard rail into a corrugated shape by only extruding the resin without any additional process.

本発明の別の目的は、ハニカム内部構造を有するために樹脂にもかかわらず高強度を有するとともに、ハニカム内部構造及び樹脂特性により付加的手段なしに衝撃吸収能力を保持する樹脂製ガードレールを提供することである。   Another object of the present invention is to provide a resin guardrail that has high strength in spite of resin because of having a honeycomb internal structure, and retains shock absorbing ability without additional means due to the honeycomb internal structure and resin characteristics. That is.

本発明のさらに別の目的は、ガードプレートに蛍光物質を添加することにより夜間の視認が容易になった樹脂製ガードレールを提供することである。   Still another object of the present invention is to provide a resin guardrail that is easily visible at night by adding a fluorescent material to the guard plate.

上記目的を達成するために、本発明は、ポストと、ポストに結合された複数のガードプレートと、ガードプレート同士を結合する結合部材とを有する樹脂製ガードレールを提供する。ガードプレートの各ガードプレートは押出し成形により製造される。ガードプレートは、断面が波形であり、後方に突出して平坦部を有する後方リッジ部と前方に突出した前方リッジ部とを有する中空基体を有する。後方リッジ部の平坦部及び前方リッジ部にそれぞれ第一及び第二の固定用孔が形成されており、第一及び第二の固定用孔を有する領域に補強用中実部が設けられている。ガードプレートはさらに、基体の中空部内でその上端及び下端を連結し、前記基体と同じ断面形状を有する波形リブと、波形リブ間及び波形リブと基体の内面との間を結合するために交互に配列された水平リブとを有する。   To achieve the above object, the present invention provides a resin guardrail having a post, a plurality of guard plates coupled to the posts, and a coupling member for coupling the guard plates to each other. Each guard plate of the guard plate is manufactured by extrusion molding. The guard plate has a corrugated cross section, and has a hollow base body having a rear ridge portion projecting rearward and having a flat portion, and a front ridge portion projecting forward. First and second fixing holes are respectively formed in the flat portion and the front ridge portion of the rear ridge portion, and a reinforcing solid portion is provided in a region having the first and second fixing holes. . The guard plate further connects the upper end and the lower end within the hollow portion of the base body, and alternately connects the corrugated ribs having the same cross-sectional shape as the base body, and the corrugated ribs and the corrugated ribs and the inner surface of the base body. And arranged horizontal ribs.

ガードプレートは、樹脂と蛍光物質又は夜光物質との混合物を用いて押出し成形しても良い。   The guard plate may be extruded using a mixture of a resin and a fluorescent material or a luminescent material.

本発明のガードレールのガードプレートは、樹脂の使用量を極めて少なくしているにもかかわらず高い強度及び弾性を有するので、車が道路から飛び出すのを防ぐのに十分な性能を有するとともに、車に衝突したときのドライバーへの衝撃を最大限抑えることができる。さらに自己発光又は光反射物質を樹脂に混入することにより、夜間の視認性を確保できる。   Since the guard plate of the guard rail of the present invention has high strength and elasticity despite the extremely small amount of resin used, it has sufficient performance to prevent the car from jumping off the road and The impact on the driver in the event of a collision can be minimized. Furthermore, nighttime visibility can be ensured by mixing a self-luminous or light reflecting material into the resin.

本発明の好適な一実施例を図２及び図３を参照して以下詳細に説明する。   A preferred embodiment of the present invention will now be described in detail with reference to FIGS.

上述したように、ガードレールの主要部をなすガードプレートは樹脂からなり、樹脂の弱点である強度を高め、押出し成形による製造を可能にするために以下の構造を有する。   As described above, the guard plate forming the main part of the guard rail is made of resin, and has the following structure in order to increase the strength, which is a weak point of the resin, and to enable manufacture by extrusion molding.

すなわち、ポストと、ポストに結合した複数のガードプレートと、ガードプレート同士を結合する結合部材とを有するガードレールにおいて、各ガードプレート10は中空パネル状の基体100を有する。基体は断面が全体的に波形であり、後方に突出した一つ以上の後方リッジ部110と前方に突出した一つ以上の前方リッジ部120とを有する。   That is, in a guard rail having a post, a plurality of guard plates coupled to the posts, and a coupling member coupling the guard plates, each guard plate 10 has a hollow panel-like base body 100. The base is generally corrugated in cross section and has one or more rear ridges 110 projecting rearward and one or more front ridges 120 projecting forward.

各後方リッジ部100は平坦部111を有する。平坦部111には、ガードプレートをポスト20にネジで固定するための第一の固定用孔112が一つ以上形成されている。各前方リッジ部120には、結合部材をガードプレートに固定するための第二の固定用孔121が形成されている。第一及び第二の固定用孔112，121が形成された領域には、固定強度を維持するために、ガードプレート10の長手方向に延在する中実部130が設けられている。   Each rear ridge portion 100 has a flat portion 111. One or more first fixing holes 112 for fixing the guard plate to the post 20 with screws are formed in the flat portion 111. Each front ridge portion 120 is formed with a second fixing hole 121 for fixing the coupling member to the guard plate. In the region where the first and second fixing holes 112 and 121 are formed, a solid portion 130 extending in the longitudinal direction of the guard plate 10 is provided in order to maintain the fixing strength.

基体100の中空部101内には、その上端と下端を連結する複数の波形リブ140が設けられている。隣接した波形リブ間、及び波形リブと母体の内部壁との間には、水平リブ141が設けられている。   A plurality of corrugated ribs 140 are provided in the hollow portion 101 of the base body 100 to connect the upper and lower ends thereof. Horizontal ribs 141 are provided between the adjacent corrugated ribs and between the corrugated ribs and the inner wall of the mother body.

前後方向に隣接する水平リブ141が交互に配列されているので、波形リブ及び水平リブで形成された格子構造はハニカム構造に似ている。そのため、基体の厚さ方向の強度が高く、本発明のガードプレートは高強度を有し、車からの衝撃により破壊しにくい。その上、波形リブ及び水平リブにより形成された格子空間101aにより、衝撃吸収性を有する。   Since the horizontal ribs 141 adjacent in the front-rear direction are alternately arranged, the lattice structure formed by the corrugated ribs and the horizontal ribs is similar to the honeycomb structure. Therefore, the strength of the base in the thickness direction is high, and the guard plate of the present invention has high strength and is not easily broken by an impact from a vehicle. In addition, the lattice space 101a formed by corrugated ribs and horizontal ribs has shock absorption.

ガードプレートを製造する場合、適量の蛍光物質（又は夜光物質）を溶融樹脂に添加し、十分に混合するために数回攪拌し、得られた混合物を押出し成形する。得られるガードプレートは、蛍光物質又は夜光物質と樹脂との混合物からなるため、車のヘッドランプ又は昼間に吸収した光による自己発光により夜間に光を放射し、夜間の視認性を確保する。   When producing a guard plate, an appropriate amount of fluorescent material (or luminescent material) is added to the molten resin, stirred several times for thorough mixing, and the resulting mixture is extruded. Since the obtained guard plate is made of a mixture of a fluorescent substance or a night-light substance and a resin, light is emitted at night by self-emission by a headlamp of a car or light absorbed in the daytime, thereby ensuring nighttime visibility.

ポスト20は金属又は樹脂により形成することができる。樹脂からなる場合、ポストの強度を上げるために、金属製芯21を嵌め込むインサート成形を行うのが好ましい。ポストの下端部に取り付けるアンカー部22はポストの支持力を決めるので、金属製であるのが好ましく、またポストを貫通するのが好ましい。   The post 20 can be formed of metal or resin. When made of resin, it is preferable to perform insert molding in which the metal core 21 is fitted in order to increase the strength of the post. The anchor portion 22 attached to the lower end portion of the post determines the support force of the post, so that it is preferably made of metal and preferably penetrates the post.

上述したように、本発明のガードレールのガードプレートは、樹脂の使用量を極力抑えても高い強度及び弾性を有するので、車が道路から飛び出すのを防ぐのに十分な性能を有するとともに、車が衝突した時のドライバーへの衝撃を最大限抑えることができる。さらに、自己発光又は光受容物質を樹脂に混入すると、ドライバーによる夜間の視認性を確保できる。   As described above, since the guard plate of the guard rail of the present invention has high strength and elasticity even if the amount of resin used is suppressed as much as possible, the guard plate has sufficient performance to prevent the car from jumping out of the road. The impact on the driver in the event of a collision can be minimized. Further, when a self-luminous or photoreceptive material is mixed in the resin, night visibility by a driver can be ensured.
