Precast concrete products - Floor plates for floor systems
This European standard deals with the requirements, the basic performance criteria and evaluation of conformity for precast floor plates made of reinforced or prestressed normal weight concrete according to EN 1992 1 1:2004, used in conjunction with cast-in-situ concrete (topping) for the construction of composite floor slabs. Annex B gives different types of composite slabs made with floor plates.
These floor plates, with or without void formers, can include lattice girders or stiffening ribs incorporated during the precasting.
They shall be manufactured in factories by casting, slip forming or extrusion.
The products covered by this standard are intended to be used as part of structural floors in applications such as:
- floors and roofs of buildings (including industrial and storage buildings, public buildings as schools, hospitals, etc.);
- parking/circulation areas;
- cover for culverts;
- etc.
The products may be used in seismic areas provided they fulfil the requirements specific to this use.
This standard does not cover:
- reinforced floor plates with a nominal thickness less than 40 mm;
- prestressed floor plates with a nominal thickness less than 50 mm;
- floor plates with a very smooth upper face, such as defined in 6.2.5 of EN 1992-1-1:2004.

Geschossdecken von Gebäuden (einschließlich Industrie- und Lagergebäude, öffentliche Gebäude wie z. B. Schulen, Krankenhäuser usw.);
Parkflächen und Verkehrsflächen;
Abdeckung von Gräben;
usw.
Diese Produkte dürfen in Erdbebengebieten eingesetzt werden, sofern sie die für diesen Fall geltenden besonderen Anforderungen erfüllen.
Die Norm gilt nicht für:
Stahlbeton-Fertigteilplatten mit einer Nenndicke kleiner als 40 mm;
Spannbeton-Fertigteilplatten mit einer Nenndicke kleiner als 50 mm;
Fertigteilplatten mit sehr glatter Oberfläche, die in EN 1992 1 1:2004, 6.2.5 festgelegt sind.

EN 13747:2005 (E) 5 Foreword This document (EN 13747:2005) has been prepared by Technical Committee CEN/TC 229 “Precast concrete products”, the secretariat of which is held by AFNOR, and was examined by and agreed with a joint working party appointed by the Liaison Group CEN/TC229-TC250, particularly for its compatibility with structural Eurocodes. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2006, and conflicting national standards shall be withdrawn at the latest by April 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. 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 89/106/EEC. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. 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 products, from which also the relevant requirements of the EN 206-1 : Concrete — Part 1 : Specification, performances, production and conformity 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: Execution of concrete structures – Part 1: Common rules, which has at the moment the status of a European prestandard. In all countries it can be accompanied by alternatives for national application and it shall not be treated as a European standard. The programme of standards for structural precast concrete products comprises the following standards, in some cases consisting on 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 13747, Precast concrete products — Floor plates for floor systems prEN 15037-1, Precast concrete products — Beam-and-block floor systems – Part 1: Beams PrEN 15037-2, Precast concrete products — Beam and blocks floor systems – Part 2: Blocks EN 13224, Precast concrete products — Ribbed floor elements EN 13225, Precast concrete products — Linear structural elements prEN 14992, Precast concrete products — Wall elements

Where, in default of applicability conditions of EN Eurocodes to the works of destination, design Provisions other than EN Eurocodes are used for mechanical strength and/or fire resistance, the conditions to affix CE marking to the product are described in ZA.3.4. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
EN 13747:2005 (E) 7 Introduction The evaluation of conformity given in this standard refers to the completed precast elements which are supplied to the market and covers all the production operations carried out in the factory. For design rules reference is made to EN 1992-1-1:2004. Additional complementary rules are provided where necessary. In clauses 4.3.3 and 4.3.4, the present standard includes specific provisions resulting from the application of EN 1992-1-1:2004 and EN 1992-1-2:2004 rules made specific for the concerned product. The use of these provisions is consistent with a design of works made with EN 1992-1-1:2004 and EN 1992-1-2:2004.

Annex B gives different types of composite slabs made with floor plates. These floor plates, with or without void formers, can include lattice girders or stiffening ribs incorporated during the precasting. They shall be manufactured in factories by casting, slip forming or extrusion.

For general terms EN 13369:2004 shall apply. 3.1 Floor plates 3.1.1 floor plate generally reinforced or prestressed concrete plates are used as permanent formwork for cast-in-situ concrete, which, when hardened, forms a structurally composite slab with the floor plate NOTE Some floor plates may be used as formwork for cast-in-situ concrete, with no contribution to the strength of the finished floor. 3.1.2 reinforced floor plate floor plate in which reinforcing steel constitutes
the main reinforcement of the composite slab 3.1.3 prestressed floor plate floor plate in which the prestressing steel constitutes all or part of the main reinforcement of the composite slab 3.1.4 floor plate with lattice girders floor plate in which continuous lattice girders are incorporated generally in the longitudinal direction (i.e. parallel to the span) to provide strength and rigidity for transient situations 3.1.5 floor plate with ribs floor plate in which continuous stiffening ribs are positioned generally in the longitudinal direction (i.e. parallel to the span) to provide strength and rigidity for transient situations 3.2 lattice girders two dimensional or three dimensional metallic structure comprising an upper chord, one or more lower chords and continuous or discontinuous diagonals which are welded or mechanically connected to the chords Figure 1 gives some examples of lattice girders.
a) continuous diagonals
b) continuous diagonals with steel profile unfilled with concrete
