This European Standard shall be given the status of a national standard, either by publicat
22、ion of an identical text or by endorsement, at the latest by May 2012, and conflicting national standards shall be withdrawn at the latest by August 2013. 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 no
23、t be held responsible for identifying any or all such patent rights. This document supersedes EN 13224:2004+A1:2007. Significant technical changes compared to the previous version are: a) change in the scope to also cover elements with bottom slab (as shown in Annex A); b) deletion of the requiremen
24、t on planarity (in 4.3.1.1 and 5.2); c) deletion of the requirement on camber or sag (in 4.3.1.1 and 5.2); d) addition of a rule for elements without shear reinforcement in 4.3.3.3; e) adoption of the new template for Annex ZA. This document has been prepared under a mandate given to CEN by the Euro
25、pean Commission and the European Free Trade Association, and supports essential requirements of the Construction Products Directive (89/106/EEC) of the European Union (EU). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This standard is o
26、ne 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 r
27、eferences 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 EN 13670:2009 Exe
28、cution of concrete structures. In all countries it can be accompanied by alternatives for national application. 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
29、core slabs EN 12794, Precast concrete products Foundation piles EN 12843, Precast concrete products Masts and poles DIN EN 13224:2012-01 EN 13224:2011 (E) 5 EN 13224, Precast concrete products Ribbed floor elements EN 13225, Precast concrete products Linear structural elements EN 13693, Precast conc

Where,
32、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 Regu
33、lations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Ma
34、lta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. DIN EN 13224:2012-01 EN 13224:2011 (E) 6 Introduction The evaluation of conformity given in this standard refers to the completed precast elements which are supplied to the mar
35、ket and covers all the production operations carried out in the factory. For design rules and resistance to fire, reference is made to EN 1992-1-1 and EN 1992-1-2. Additional complementary rules are provided where necessary. 4.3.3 and 4.3.4 include specific provisions resulting from the application
36、of EN 1992-1-1, and EN 1992-1-2 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 and EN 1992-1-2. DIN EN 13224:2012-01 EN 13224:2011 (E) 7 1 Scope This document identifies the requirements, the basic performance cri
37、teria and evaluation of conformity for precast ribbed elements made of reinforced or prestressed normal weight concrete, used in floors or roofs. The elements consist of a top and/or bottom slab and one or more (usually two) ribs; transverse ribs may also be present. Some examples of precast element
38、s considered in this document are shown in Annex A. Specific requirements for minor floor elements are listed in Annex B. This document covers terminology, performance criteria, tolerances, relevant physical properties, test methods and aspects of transport and erection. This document does not cover
39、 load-bearing capacity determined by testing. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any a
