Description
Foreliggende oppfinnelse angår en anordning ved veirekkverk der rekkverket omfatter hule festestolper av et egnet plastmateriale med en fra stolpe til stolpe forløpende og til stolpene festet rekkverksskinne, fortrinnsvis av metall. The present invention relates to a device for road guardrails where the guardrail comprises hollow fastening posts of a suitable plastic material with a railing rail running from post to post and attached to the posts, preferably made of metal.
I de fleste land har veimyndighetene fastsatt egne krav når det gjelder utforming og montering av veirekkverk. I Europa (EØS) er det utarbeidet standardiserte krav til veirekkverk og utprøvingen av slike. I november 1998 ble disse kravene akseptert som norsk standard NS-EN 1318-1. In most countries, the road authorities have set their own requirements when it comes to the design and installation of road railings. In Europe (EEA), standardized requirements have been drawn up for road guardrails and the testing of such. In November 1998, these requirements were accepted as Norwegian standard NS-EN 1318-1.
Rekkverk deles inn i klasser. Hvilke klasser veimyndighetene velger å benytte er avhengig av hvilke veier de skal monteres langs, hvilke type kjøretøyer som bruker veiene, hvilke hastigheter som er tillatt på veiene og de geografiske forhold langs veiene. Railings are divided into classes. Which classes the road authorities choose to use depends on which roads they are to be installed along, which types of vehicles use the roads, which speeds are permitted on the roads and the geographical conditions along the roads.
Rekkverkene blir godkjent av veimyndighetene i de respektive land basert på normerte kollisjonsprøver i full skala ved godkjente laboratorier i Europa. The guardrails are approved by the road authorities in the respective countries based on standardized full-scale crash tests at approved laboratories in Europe.
I de fleste aktuelle land over hele verden benyttes det i dag en standardisert, profilert stålskinne festet til en bestemt type stål-stolpe med såkalt sigma-profil og med en avstand mellom stolpene på 2 og 4 meter. In most relevant countries around the world, a standardized, profiled steel rail attached to a specific type of steel post with a so-called sigma profile and with a distance between the posts of 2 and 4 meters is used today.
I enkelte land, for eksempel Norge og Canada, benyttes det i det alt vesentlige trestolper der de som benyttes i Norge i det vesentlige er runde mens de canadiske har et firkantet tverrsnitt. In some countries, for example Norway and Canada, wooden posts are generally used, where those used in Norway are essentially round, while the Canadian ones have a square cross-section.
Et veirekkverk skal prinsipalt forhindre personskade ved at kjøretøyer forhindres i å kjøre utfor veien. A road guardrail is primarily intended to prevent personal injury by preventing vehicles from driving off the road.
Imidlertid er det her en rekke hensyn som må ivaretas. However, there are a number of considerations that must be taken into account.
Rekkverket skal ved påkjørsel bringe bilen tilbake på veien med minst mulig skade på bil, fører og passasjerer. Dette oppnås ved at rekkverket gir noe efter ved kollisjon slik at bilens hastighet bremses ned, og så føres bilen tilbake på veien. In the event of a collision, the guardrail must bring the car back onto the road with the least possible damage to the car, driver and passengers. This is achieved by the guardrail giving way in the event of a collision so that the car's speed is slowed down, and the car is then guided back onto the road.
Rekkverket må ved påkjørsel ikke svikte så mye at bilen kjører ut i veigrøften, ned skråning eller utfor stup. In the event of a collision, the guardrail must not fail so much that the car drives into the road ditch, down a slope or off a cliff.
Det er helt vesentlig at rekkverket ikke trekkes ned mot bakken ved nedbøyning av festestolpene da dette vil føre til at bilen kjører over rekkverket med derav katastrofale følger. It is absolutely essential that the railing is not pulled down towards the ground when the fixing posts are bent, as this will cause the car to drive over the railing with disastrous consequences.
Rekkverket må ikke være så fjærende elastisk at det kaster kjøretøyet for langt ut i veien efter kollisjon med fare for å treffe møtende trafikk. The guardrail must not be so springy and elastic that it throws the vehicle too far out into the road after a collision with the risk of hitting oncoming traffic.
Til slutt må rekkverket ha en slik egenskap og virkemåte at det gir en samtidig ned-bremsing ved utbøyning, friksjon med rekkverkskinnen og nedbøyning av festestolpene på avdempet måte slik at belastningen (retardasjonen) for fører og passasjer ikke blir for stor. Finally, the guardrail must have such a characteristic and function that it provides a simultaneous downward braking during deflection, friction with the guardrail rail and downward deflection of the fastening posts in a subdued manner so that the load (retardation) for the driver and passenger does not become too great.
I de ovenfor nevnte CEN-normer er det fastsatt grenser som må oppfylles for alle disse forskjellige områder. Det er her viktig å påpeke at det ikke foretas prøver med eller gis godkjennelse for enkeltkomponenter i rekkverk, det er et ferdig, fullstendig rekkverk som testes ved kollisjoner i naturlig målestokk og resultatet som eventuelt godkjennes er resultatet av samvirket mellom alle deler som inngår i rekkeverket. In the CEN standards mentioned above, limits have been set that must be met for all these different areas. It is important to point out here that tests are not carried out with or approval given for individual components of railings, it is a finished, complete railing that is tested in collisions on a natural scale and the result that is possibly approved is the result of the cooperation between all parts that are part of the railing .
De problemer man søker å sikre seg mot ved oppfinnelsens gjenstand er de som er skissert ovenfor, nemlig at tre-stolper splintres under dannelse av livsfarlige, skarpe eller spisse avbrukne deler som ved kollisjon kan slynges rundt i området, at rekkverk og stolper ikke er så stive at de i seg selv utgjør en fare, at ikke rekkverket trekkes ned mot bakken når stolpene kjøres ned slik at man unngår en overkjøring, eller at rekkverket er så fjærende at det slynger bilen inn i trafikken og eventuelt mot møtende trafikk. The problems sought to be safeguarded against with the object of the invention are those outlined above, namely that wooden posts splinter while forming life-threatening, sharp or pointed worn parts which can be flung around the area in the event of a collision, that railings and posts are not so rigid that they in themselves pose a danger, that the guardrail is not pulled down towards the ground when the posts are driven down so as to avoid an overrun, or that the guardrail is so springy that it flings the car into traffic and possibly towards oncoming traffic.
Samtidig har økonomiske aspekter knyttet til innkjøp og vedlikehold også en viss betydning i tillegg til at rekkverket selvfølgelig bør være enkelt å montere og i gitte tilfeller også enkel å reparere. Et viktig aspekt er levetid før utskifting er påtenkt. At the same time, financial aspects related to purchasing and maintenance also have a certain importance, in addition to the fact that the railing should of course be easy to install and, in certain cases, also easy to repair. An important aspect is the lifespan before replacement is contemplated.
Foreliggende oppfinnelse angår således en anordning ved veirekkverk omfattende hule festestolper av et egnet plastmateriale med en fra stolpe til stolpe forløpende og til stolpene festet rekkverksskinne av metall der skinnen er festet til stolpen med bolter med tilhørende muttere, og denne anordning karakteriseres ved at bolthullet i skinnen er forsterket med en underlagsskive eller lignende mellom mutteren (hodet) og skinnen mens bolthullet i stolpens vegg har en diameter større enn boltens diameter men noe mindre enn bolthodets (mutterens) diameter, idet bolthodet (mutteren) ligger direkte an mot veggen av stolpen. The present invention thus relates to a device for road railings comprising hollow fastening posts of a suitable plastic material with a metal railing rail running from post to post and attached to the posts, where the rail is attached to the post with bolts with associated nuts, and this device is characterized by the bolt hole in the rail is reinforced with a washer or similar between the nut (head) and the rail, while the bolt hole in the wall of the post has a diameter larger than the diameter of the bolt but somewhat smaller than the diameter of the bolt head (nut), as the bolt head (nut) lies directly against the wall of the post.
Foreliggende oppfinnelse beskriver således et innfestingssystem for feste mellom stolpe og rekkverksskinne som gjør det mulig å oppnå et kollisjonsforløp som, slik det er påvist ved tester ved et godkjent svensk trafikklaboratorium, er betydelig gunstigere når det gjelder de fleste av de ovenfor nevnte krav som stilles i CEN-normer, nå Norsk Standard NS-EN 1319-1, enn det som oppnås ved konvensjonelle tre- eller stål-stolper. The present invention thus describes an attachment system for fastening between a post and a railing rail which makes it possible to achieve a collision course which, as has been demonstrated by tests at an approved Swedish traffic laboratory, is significantly more favorable when it comes to most of the above-mentioned requirements set in CEN standards, now Norwegian Standard NS-EN 1319-1, than what is achieved with conventional wooden or steel posts.
Foreliggende oppfinnelse skal illustreres nærmere ved hjelp av de vedlagte figurer der: figur 1 viser festing av en rekkverksskinne til en stolpe i en foretrukken The present invention shall be illustrated in more detail with the help of the attached figures where: figure 1 shows the attachment of a railing rail to a post in a preferred
utførelsesform; og embodiment; and
I figur 1 er rekkverksskinnen 2 festet til stolpen 1 ved hjelp av en bolt 3 som går gjennom rekkverksskinnen 2 og den nærmestliggende vegg 5' av stolpen 1. In figure 1, the railing rail 2 is attached to the post 1 by means of a bolt 3 which passes through the railing rail 2 and the nearest wall 5' of the post 1.
I den viste utførelsesform befinner bolthodet 8 seg på veisiden av skinnen 2 mens den tilvarende festemutter 4 befinner seg inne i den hule stolpe. In the embodiment shown, the bolt head 8 is located on the road side of the rail 2, while the remaining fixing nut 4 is located inside the hollow post.
Bolten kan selvfølgelig settes i andre veien slik at hodet 8 befinner seg inne i stolpen 1 og mutteren 4 befinner seg på utsiden. The bolt can of course be put in the other way so that the head 8 is inside the post 1 and the nut 4 is on the outside.
Mellom hodet 8 (eller mutteren 4) er det lagt en stoppskive mens en slik stoppskive ikke er tilstede mellom mutteren 4 (hodet 8) og veggen 5' av stolpen 1. A stop disc is placed between the head 8 (or the nut 4), while such a stop disc is not present between the nut 4 (the head 8) and the wall 5' of the post 1.
Tvert imot er veggen 1 i området for bolten "svekket" ved at bolthullet 7 har en større diameter enn bolten 3. On the contrary, the wall 1 in the area of the bolt is "weakened" in that the bolt hole 7 has a larger diameter than the bolt 3.
På den annen side må hullet 7 i veggen 5' ikke være større enn at det overspennes av mutteren 4 (hodet 8) slik at tilstrekkelig feste ved normale påkjenninger er sikret. On the other hand, the hole 7 in the wall 5' must not be larger than it is spanned by the nut 4 (head 8) so that sufficient attachment under normal stresses is ensured.
Andre typer svekninger er selvfølgelig tenkbare og fagmannen vil klart innse slike muligheter. Other types of impairment are of course conceivable and the person skilled in the art will clearly realize such possibilities.
Fordelene ved denne innfestingsmåte skal diskuteres nærmere nedenfor. The advantages of this fixing method will be discussed in more detail below.
Det har vist seg at plaststolper 1 ved påkjørsel gir efter og bøyes ned mot bakken under bilen men fordi innfestingen som beskrevet ovenfor er "svekket" og tilpasset, vil skinnen 2 på grunn av utformingen av hullet 7 (eller en tilsvarende svekning) i stolpen rives løs før skinnen 1 trekkes ned mot bakken. It has been shown that the plastic posts 1 give way in a collision and bend down towards the ground under the car, but because the attachment as described above is "weakened" and adapted, the rail 2 will tear due to the design of the hole 7 (or a corresponding weakening) in the post loose before rail 1 is pulled down towards the ground.
Dette betyr at stolpen 1 i seg selv ikke utgjør noe hinder, den vil bøyes elastisk under bilen, men skinnen 2 vil virke som et bånd som fanger opp bilen og lede den tilbake i kjørebanen. This means that the post 1 in itself does not constitute an obstacle, it will bend elastically under the car, but the rail 2 will act as a band that catches the car and guides it back into the roadway.
Plastmaterialets store evne til å absorbere energi ved deformasjon, dets fleksibilitet, dimensjonering av plaststolpen 1 og ikke minst innfesting av rekkverksskinnen 2 til stolpen 1, gir et meget gunstig kollisjonsforløp, vesentlig bedre enn for stål- og tre-stolper, noe som i den senere tid er bekreftet ved laboratorieforsøk i fullskala, men som man ikke har vært fullt ut oppmerksom på tidligere. The plastic material's great ability to absorb energy during deformation, its flexibility, dimensioning of the plastic post 1 and not least the attachment of the railing rail 2 to the post 1, provides a very favorable collision course, significantly better than for steel and wooden posts, which in the later time has been confirmed by full-scale laboratory experiments, but of which one has not been fully aware in the past.
Dette innfestingssystem representerer således et betydelig bidrag til å øke trafikksikkerhet og ikke minst til reduserte skader ved kollisjon mot rekkverket. This fastening system thus represents a significant contribution to increasing traffic safety and not least to reduced injuries in the event of a collision with the guardrail.
Stolper av plast gir i tillegg et meget miljøvennlig produkt, er lett å vedlikeholde og har meget lang levetid og kan resirkuleres, alt vesentlige fordeler i forhold til de tidligere benyttede stolper av impregnert tre eller galvanisert metall. Plastic poles also provide a very environmentally friendly product, are easy to maintain and have a very long life and can be recycled, all significant advantages compared to the previously used poles of impregnated wood or galvanized metal.
Det har vist seg at de nevnte fordeler oppnås med hule plaststolper uten noen form for innvendig ribbeforsterkning eller lignende. Det har videre vist seg at hule stolper som er "overkjørt" av en bil vil rette seg opp og faktisk gjenvinne en vesentlig del av sin opprinnelige styrke slik at den umiddelbart efter kollisjon vil virke som om ikke annet enn optisk hindring for efterfølgende biler, kan tjene som feste for de varselbånd som måtte henges opp, og tjene som nytt feste ved en første reparasjon i de tilfeller en mere omfattende reparasjon må utsettes av forskjellige grunner. It has been shown that the aforementioned advantages are achieved with hollow plastic posts without any form of internal rib reinforcement or the like. It has also been shown that hollow posts that have been "run over" by a car will straighten themselves and actually recover a significant part of their original strength so that immediately after a collision it will appear as nothing more than an optical obstacle for following cars, serve as an attachment for the warning tapes that had to be hung, and serve as a new attachment for a first repair in cases where a more extensive repair has to be postponed for various reasons.
En ytterligere fordel ved bruk av slike noe elastiske stolper er at de gir litt efter når snøploger, ofte i svinger, blir presset mot rekkverksskinnen i forbindelse med brøyting av veier om vinteren. Derved unngås skading som ofte påføres rekkverk under vanskelige værforhold. A further advantage of using such somewhat elastic posts is that they give way slightly when snow ploughs, often in bends, are pressed against the guard rail in connection with plowing roads in winter. This avoids damage that is often inflicted on railings in difficult weather conditions.
Plaststolper har som nevnt ovenfor en viss grad av fleksibilitet og vil vende tilbake til opprinnelig form efter at snøplogen har passert. As mentioned above, plastic poles have a certain degree of flexibility and will return to their original shape after the snow plow has passed.
