Precast concrete products - Box culverts
This European Standard deals with both large (structural) and small (non-structural or light structural) box culverts of rectangular cross-section formed monolithically and designed as continuous elements with a joint detail shaped to allow the possible incorporation of sealing materials. Box culverts can be used for creation of voids below ground for conveyance and storage of materials. e.g. conveyance and storage of wastewater, cable tunnels and subways
For the purposes of this European Standard, box culverts having internal cross-sectional dimensions (W and H in Figure 1) less than or equal to 1 250 mm are considered as small (non-structural or light structural). All other units are defined as large. The elements are generally manufactured in factories using either normal weight or lightweight concrete and usually require reinforcing steel. This standard does not include units manufactured from autoclaved aerated concrete, nor prefabricated reinforced box culverts of lightweight concrete with open structure.
Each unit is structurally complete. They are used in combination to form a total structure of appropriate length (including joints) and capacity.
Betonfertigteile - Hohlkastenelemente
Diese Europäische Norm behandelt sowohl große (tragende) als auch kleine (nicht tragende oder eine
geringe Tragfähigkeit aufweisende) Hohlkastenelemente mit rechteckigem Querschnitt, die monolithisch
hergestellt werden und als aneinander gereihte Elemente mit einer Fugenausbildung entworfen sind, wobei
die Fuge so geformt ist, dass Dichtstoffe eingebracht werden können. Hohlkastenelemente können dazu
verwendet werden, unterirdische Hohlräume zu schaffen, die für den Transport oder die Lagerung von
Materialien, z. B. für den Transport und Lagerung von Abwasser, als Kabelkanäle oder als Unterführungen,
genutzt werden.
Für die Anwendung dieser Norm sollten Hohlkastenelemente mit Innenquerschnittsmaßen (W und H in Bild 1)
≤ 1 250 mm als klein (nicht tragend oder eine geringe Tragfähigkeit aufweisend) angesehen werden. Sämtliche
anderen Elemente sollten als groß definiert werden. Im Allgemeinen werden die Elemente in Werken aus
Normal- oder Leichtbeton hergestellt und erfordern meist eine Betonstahlbewehrung. Die vorliegende Norm
behandelt weder Elemente, die aus Porenbeton hergestellt werden, noch vorgefertigte Hohlkastenelemente
aus Leichtbeton mit offenem Gefüge.
Alle Elemente sind in statisch-konstruktiver Hinsicht vollständig ausgebildet. Sie werden aneinander gereiht
eingesetzt, sodass sich eine Gesamtkonstruktion passender Länge (einschließlich Fugen) und Tragfähigkeit
ergibt.
Produits préfabriqués en béton - Cadres enterrés
La présente norme traite à la fois des cadres enterrés grands (structurels) et petits (non structurels ou peu structurels) de section transversale rectangulaire, monolithiques et conçus comme des éléments continus avec un détail de joint formé pour permettre l’incorporation éventuelle de matériaux d’étanchéité. Les cadres enterrés peuvent être utilisés pour créer des vides au-dessous du niveau du sol à des fins de transport et de stockage, par exemple pour le transport et le stockage des eaux résiduaires, les galeries techniques et les passages souterrains.
#Pour les besoins de la présente Norme européenne, les cadres enterrés ayant des dimensions internes de section transversale (W et H sur la Figure 1) inférieures ou égales à 1 250 mm sont considérés comme petits (non structurels ou peu structurels). Tous les autres éléments sont qualifiés de grands.$ Les éléments sont généralement fabriqués en usine avec du béton de granulats normaux ou légers et nécessitent généralement de l’acier de béton armé passif. La présente norme n’inclut pas les éléments fabriqués à partir de béton cellulaire autoclavé, ni les cadres enterrés en béton armé réalisés en béton léger à structure ouverte.
Tous les éléments sont structurellement fermés. Ils sont combinés pour former une structure complète de longueur (avec les joints) et de capacité appropriées.
Montažni betonski izdelki - Škatlasti nosilci
Ta evropski standard obravnava velike (konstrukcijske) in majhne (nekonstrukcijske ali lahke konstrukcijske) monolitne škatlaste nosilce s pravokotnim prerezom, zasnovane kot neprekinjene elemente s spojem, ki omogoča morebitna vključitev tesnilnih materialov. Škatlasti nosilci se lahko uporabljajo pri konstrukciji podzemnih prostorov za prenos in skladiščenje materialov, npr. za prenos in skladiščenje odpadne vode, kabelske kanale in podvoze.
Za namene tega evropskega standarda se škatlasti nosilci, ki imajo notranje mere v prerezu (W in H na sliki 1) manjše kot ali enake 1 250 mm, obravnavajo kot majhni (nekonstrukcijski ali lahki konstrukcijski) nosilci. Vse druge enote so opredeljene kot velike. Elementi so ponavadi izdelani v tovarnah iz normalno težkega ali lahkega betona in običajno je treba uporabiti armaturno jeklo. Ta standard ne vključuje enot iz avtoklaviranega celičnega betona in predizdelanih armiranih škatlastih nosilcev iz lahkega betona z odprto konstrukcijo.
Vsaka enota je konstrukcijsko zaključena. Skupaj oblikujejo celotno konstrukcijo ustrezne dolžine (vključno s spoji) in zmogljivosti.

# $. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). #deleted text$ This standard is one of a series of product standards for precast concrete products. For common aspects reference is made to EN 13369, Common rules for precast concrete products, from which also the relevant requirements of EN 206-1, Concrete Part 1: Specification, performance, production and conformity are taken. The references to EN 13369:2004 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements. #Eurocodes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by EN 13670, Execution of concrete structures.$ The programme of standards for structural precast concrete products comprises the following standards, in some cases consisting of several parts: EN 1168, Precast concrete products Hollow core slabs EN 12794, Precast concrete products Foundation piles EN 12843, Precast concrete products Masts and poles EN 13225, Precast concrete products Linear structural elements EN 13693, Precast concrete products Special roof elements EN 13747, Precast concrete products Floor plates for floor systems SIST EN 14844:2006+A2:2012
