    eline zatitne ograde za cestovne prometnice (branici)

    Suvremene cestovne prometnice za mot-orna vozila omoguuju postizanje veih brzina, mirnu i udobnu vonju, a istovre-meno pruaju visok stupanj sigurnosti za vozila koja se kreu tim prometnicama.Jedan od elemenata sigurnosti u ces-tovnom prometu je adekvatno i po pro-jektu postavljena elina zatitna ograda. elinu zatitnu ogradu trebalo bi postaviti tamo gdje je opasnost od udara vozila u zatitnu ogradu manja od opasnosti prijelaza vozila u opasnu zonu koja je odvojena zatitnom ogradom.

    Modern highways facilitate smooth and comfortable driving at higher speeds, while at the same time providing a high level of safety for drivers. Properly installed steel guard-rails are an important safety element in road traffic. Such guard-rails should be installed at all dangerous spots along a road. With their shape and outer appearance they become an optical guiding element, especially if steel guard-rails are fitted with reflecting lights. The purpose of steel guard-rails is to stop the deflected vehicle and prevent uncon-trolled path of the vehicle. In addition, it greatly reduces the force of impact owing to its flexibility.

    Steel guard-rails for roads

    elina zatitna ograda se postavlja na prometnici tako da svojim oblikom i vanjskim izgledom bude element optikog voenja, napose ako se u elinu zatitnu ogradu ugrade svjetlosna reflektirajua tijela.Svrha eline zatitne ograde je da zadri skrenuto vozilo i sprijei nekontroliranu putanju vozila, a radi svoje gipkosti, da bitno umanji posljedice nezgode

    Elementi elinih zatitnih ograda za cestovne prometnice, a obuhvaeni ovim katalogom, rezultat su prakse i nastojanja da se doe do jedinstvenog tipa eline zatitne ograde.Postavljanje eline zatitne ograde je jednostavno i brzo. Konstrukcija i sistem spajanja sastavnih elemenata omoguuju da trokovi odravanja (zamjena i popra-vak) budu niski, a istovremeno sve oper-acije jednostavne i brzo izvodljive.U Republici Hrvatskoj prihvaen je (odab-ran) jedinstven tip elemenata eline zatitne ograde za cestovne prometnice po njemakom standardu RAL-RG 620 tip B, koji je jednako vrijedan kao i tip A, ali je znatno laki, a samim tim znatno je jeftiniji.Sistem RAL-RG 620 se koristi ili kopira sa manjin modifikacijama u vie zapad-noeuropskih zemalja. Osnovna prednost ovog sistema da je njegov studijski razvoj izvren uz praktina ispitivanja (probe), time se postiglo da je mekan kod slabih kliznih naleta, naginjui se, a nepropusljiv kod naleta kamiona i vozila sa velikim kotaima.Radi nepredvidljivog naina optereenja na elinu zatitnu ogradu za cestovne prometnice, profil zatitne ograde ima oso-binu da pretrpi plastine deformacije bez loma ili djeluje unutar granica elastinosti.

    Elements of steel guard-rails for roads, which are incorporated in this brochure, are the result of practical knowledge and efforts to design a unique type of steel guard-rails. Steel guard-rails are installed easily and quickly. The design and system of link-ing component parts allows the costs of maintenance (exchange and repair) to be kept low, while all operations are simple and easy to perform. In Croatia a single type of elements of steel guard-rails has been adopted in ac-cordance with the German Standard RAL-RG 620 Type B, which is equally valuable as Type A, except for being far lighter and therefore also more cost effective. The RAL-RG 620 system is used or copied with slight modifications in a number of West European countries. The chief advantage of this system lies in the fact that it has been developed through practi-cal testing. As a result, the guard-rail is flexible in weak, sliding collisions, and impenetrable in collisions with trucks or other vehicles with large wheels. Because of unpredictable loading of steel guard-rails which are installed along roads, the guard-rail sections are capable to sustain plastic deformations without breaking or to act within elasticity limits.

    Definitions

    Guard-rail is a technically designed structure whose main purpose consists in preventing the vehicle from sliding off the designated track or deflecting from the surface of the road, i.e. to receive and stop the vehicles deflected from the lane. Rail - a profiled band made of hot rolled steel sheet of appropriate mechanical characteristics and specific length, which through deformation reduces the conse-quences of car impact. It is manufactured in three different shapes: flat, inclined or curved according to the road curvature (concave or convex).Spacer - a solid element of specific shape and size whose purpose is to establish a solid link between the rail and the post or some other support. Post - supports the spacer and/or rail; it is made of mechanically resistant material of specific profile and length for support-ing the rail in a specific position. It acts in conjunction with the spacer (if provided). Endings - rails and elements of special shape which are placed at the beginning and end of the guard-rail in order to reduce the force of impact of vehicles col-liding with the guard-rail.Band - a flat steel band of specific profile and size which connects the posts via spacers on the outer side thus creating a tension belt (chain). Demountable Belt - part of the guard-rail in the middle strip which can be easily and quickly demounted in case of diver-sion of traffic.

    Diletacija

    Na svim objektima na mjestu diletacije, elina zatitna ograda izvodi se s dil-etacionim spojem kojeg je Dl odreen projektom, (Dl=duina diletacije).

    Dilatation

    At points of dilatation the steel guard-rail on all roads, overpasses and bridges features a dilatation connection, with DI (length of dilatation) defined by project.

    Endings which are installed at the begin-ning and end of guard-rails on open road sections consist of a 12-meter-long inclined rail section, which is sunk, dug in or an-chored in the ground, with a semi-circular ending placed 2 cm above the ground. In cases where it is not possible to execute inclined endings, the guard-rail ends in semi-circular endings.

    Demontani prelazi Demountable Belt

    At a point of interruption of the middle strip, demountable belts with dilatation rails are installed, usually at a distance of 3 km, in case there is a need to divert traffic. Rails are fastened to spacers and posts by means of bolts and wedges which, if required, can be quickly and easily disas-sembled by driving the wedges out. Posts with spacers are mounted in holes made of steel tubes which are cemented in the roadway. Inclined demountable ending (DO&DDO) is 4 m long. The lowered end of the rail has a special shape and is fastened to the post with a plate installed in the concrete foundation. Demountable belt is made with two dilata-tion connections.

    Barijere za zatitu od zasljepljivanjaEN 12676-1

    Na pojedinim dionicama autocesta dolazi do dodira svjetlosnih snopova vozila koja se kreu u razliitim smjerovima.Da se izbjegne opasnost od zasljepljivanja vozaa, preporua se ugradnja barijera za zatitu od zasljepljivanja.Elementi se montiraju na posebni nosa koji se privruje na centralni dio zatitne ograde.

    1 prihvatna konstrukcija2 element za zatitu od svjetla

    On some parts of a motorway, especially at slight curves, glare is possible from vehicles headlights from opposite direc-tions.In order to reduce possibility of a driver being blinded for a short moment, it is advisable to install anti-glare protection system at these parts of a motorway.

    Anti-glare protection systemEN 12676-1

    Zatitna ograda na zidu privruje se na zidni odstojnik pomou elinih sidrenih vijaka (elinih tipli).

    Wall guard-rail is fastened to the wall spacer by means of steel anchor bolts (screw anchors).

Prema projektu izvode se boje iz palete RAL ili SIKKENS, da se izbjegne refleksija velikih ploha. Zatitne kasete se mogu izraivati iz per-formiranog aluminijskog lima.Viestruka primjena svih elemenata za zatitu od buke moe se kombinirati sa drugim sistemima za zatitu, kao to su staklene ograde i prostorne reetke.Lagane Al kasete daju optimalnu zatitu od buke na cestama, mostovima, prugama i ostalim objektima.Primjenom niza tehnikih i fizikalnih komponenata kao i naina bojanja, svi elementi imaju visoku apsorpciju i dobro se uklapaju u okolinu.Treba istai da se ispunjavaju sljedei zahtjevi: specifine osobine materijala akustiko zaklanjanje i estetika ekonominost i lagana montaa dugotrajna otpornost na starenje prilagoavanje lokalnim uvjetima nema odravanja i moe se popravljati.

    Noise Barriers for Roads

    The road equipment range of products of Dalekovod includes noise barriers. On the outside the protective elements are coated in high-quality polyethylene powder in the same quality as the facade. Accord-ing to project colours from the RAL or SIKKENS spectrum are used, in order to avoid reflection of large surfaces. Protec-tive elements can be made from preformed aluminium sheet.

    Owing to their multiple application, all elements of noise protection can be com-bined with other protection systems, such as glass fences or space rails. Light Al panels provide optimum noise protection on roads, bridges, tracks, and other structures. Thanks to application of a series of techni-cal and physical components, all elements feature high absorption and are harmoni-ously fitted in with the environment. The noise barriers meet the following requirements: Specific characteristics of material Acoustic shielding and attractive de-

    sign Cost-efficient and easy mounting Long wear resistance Adaptation to local conditions The noise barriers are maintenance-

    free and can be repaired

    Technical Description

    The absorptive part of the protective element is made of 40-mm mineral-wool plates with specific gravity of 100 kg/m3. The compound for production of mineral-wool plates is chemically processed and covered with glass, which makes the prod-uct resistant to UV-rays and atmospheric influences.The absorbent material is contained in sound-proof panels which on one side fea-ture a perforated wall - noise source side. The front part of panel has an elastic rub-ber insert corresponding in size to the fit of HE 160 profile. This kind of fit ensures the best noise protection of the entire wall in relation to the environment.The complete protective fence system with elastic structural elements - elastic over-lapping of the front and rear side of panel, application of polyethylene powder, results in full stability against the influence of wind and snow, making this type of noise barrier a very good solution.

    Nosai prometne signalizacije i putokaza

    Izgradnja novih prometnica zahtijeva u svemu drugi pristup, napose kada je rije o ukupnoj sigurnosti vozila koja se kreu tim prometnicama. Razliite vrste portala koji na potrebnim mjestima u cijelosti ili djelomino nadsvouju profil prometnice, omoguuju da se prometna signalizacija (razliiti prometni znakovi - svjetlei ili refleksivni, odreeni putokazi) uoi s vee udaljenosti, to je svakako doprinos ukup-noj sigurnosti saobraaja koji se odvija na prometnicama koje su opremljene moder-nom signalizacijom.Portali na prometnicama su eline kon-strukcije, koje se izrauju od vrue valjanih limova i profila, kvalitete prema vaaim standardima i propisima. Dimenzije pojedinih profila i limova ovise o; vrsti prometne signalizacije koja se na njih postavlja, irini prometnice koju moraju premostiti, podneblju u kojem se ugrauju (odreene zone djelovanja vjetra, pojava snijega i leda), te eventualnim posebnim zahtjevima investitora.

    Supports for Traffic Signs and Guide Posts

    Construction of new roads requires a dif-ferent approach to be adopted, notably when overall security of drivers using the roads is concerned. Different types of por-tals which fully or partially overarch the road at places where guidance is required make the road signs (various traffic signs - illuminating or reflex, guide posts) vis-ible from a greater distance, thus greatly contributing to the overall security of traffic on roads which are equipped with modern signalling devices.

    Road portals are steel structures that are made of hot rolled sheets and sections complying with the applicable standards and regulations. Sizes of particular sec-tions and sheets depend on the type of road signals they carry, the road width that needs to be spanned, the climate in which they are being put up (areas exposed to wind, occurrence of snow and ice), and special requirements of inves-tors, if any.
