Precast concrete products - Beam-and-block floor systems - Part 4: Expanded polystyrene blocks
This European Standard deals with the requirements and the basic performance criteria for blocks made in expanded polystyrene (EPS), used in conjunction with precast concrete beams in compliance with EN 15037-1, with or without cast-in-situ concrete for the construction of beam-and-block floor systems. EPS block may be totally made in EPS or combined with different materials such as plaster or wood wool. If EPS is combined with other materials, these materials should not contribute to more than 50 % of the mechanical resistance of the block. If not, the block is covered by EN 15037-5, Precast concrete products ? Beam-and-block floor systems ? Part 5: Lightweight blocks for simple formwork. Examples of typology of floor systems are given in Annex B of EN 15037-1:2008.
Betonfertigteile - Balkendecken mit Zwischenbauteilen - Teil 4: Zwischenbauteile aus Polystyrolhartschaum
Diese Europäische Norm legt die Anforderungen und die grundlegenden Leistungskriterien für Zwischenbau-teile aus Polystyrolhartschaum (EPS) fest, die zusammen mit vorgefertigten Betonbalken nach EN 15037-1 mit oder ohne Ortbeton zur Herstellung von Balkendecken mit Zwischenbauteilen verwendet werden.
EPS-Zwischenbauteile können sowohl gänzlich in Polystyrolhartschaum ausgeführt sein als auch mit unterschiedlichen Werkstoffen wie z. B. Gips oder Holzwolle kombiniert werden.
Wenn Polystyrolhartschaum mit anderen Werkstoffen kombiniert ist, sollte der Anteil dieser Werkstoffe an der mechanischen Festigkeit des Zwischenbauteils nicht mehr als 50 % betragen. Andernfalls wird das Zwischen-bauteil durch EN 15037 5 Betonfertigteile — Balkendecken mit Zwischenbauteilen — Teil 5: Zwischenbauteile aus Leichtwerkstoffen für einfache Schalungen abgedeckt.

Produits préfabriqués en béton - Systèmes de planchers à poutrelles et entrevous - Partie 4: Entrevous en polystyrène expansé
La présente Norme européenne spécifie les prescriptions et les critères de performance de base relatifs aux
entrevous en polystyrène expansé (PSE) utilisés conjointement avec des poutrelles préfabriquées en béton
conformes à l'EN 15037-1, avec ou sans béton coulé en place, pour la construction de systèmes de planchers à
poutrelles et entrevous.
Un entrevous en PSE peut être entièrement constitué de PSE ou être associé à différents matériaux tels que le plâtre
ou la laine de bois.
Si le PSE est combiné à d'autres matériaux, il convient que ceux-ci ne contribuent pas à plus de 50 % de la résistance

Ta evropski standard obravnava zahteve in osnovna merila učinkovitosti za polnila, izdelana iz ekspandiranega polistirena (EPS), ki se uporabljajo v povezavi z montažnimi betonskimi nosilci v skladu s standardom EN 15037-1 z ali brez na gradbišču zmešanega betona za izgradnjo talnih sistemov iz nosilcev in polnil. Polnilo EPS je lahko v celoti izdelano iz ekspandiranega polistirena ali kombinirano z različnimi materiali, kot je mavec ali lesna volna. Če je ekspandirani polistiren kombiniran z drugimi materiali, le-ti ne smejo prispevati več kot 50 % mehanske odpornosti polnila. V nasprotnem primeru polnilo zajema standard EN 15037-5, Montažni betonski izdelki – Talni sistemi iz nosilcev in polnil – 5. del: Lahka polnila za enostavne opaže.

For common aspects of concrete products, reference is made to EN 13369, from which also the relevant requirements of the EN 206-1 are taken. The references to EN 13369 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 ENV 13670-1. In all countries it may be accompanied by alternatives for national application and it should not be treated as a European Standard.
