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of an identical text or by endorsement, at the latest by May 2012, and conflicting national standards shall be withdrawn at the latest by Augu

CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13224:2004+A1:2007. Significant technical changes
20、 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 requirement 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 with
21、out 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 European Commission and the European Free Trade Association, and supports essential requirements of the Construction Products Directive (89/106/EEC) o
22、f 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 one of a series of product standards for precast concrete products. For common aspects, reference is made to EN 13369: Common rules for precast pro
23、ducts, 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. Euro
24、codes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by EN 13670:2009 Execution of concrete structures. In all countries it can be accompanied by alternatives for national application. The programme of standards for str
25、uctural 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 BS EN 13224:2011EN 13224:2011

31、11 (E) 6 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 and resistance to fire, reference is made to EN 1992-1-1 and EN 19
32、92-1-2. Additional complementary rules are provided where necessary. 4.3.3 and 4.3.4 include specific provisions resulting from the application 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
33、 1992-1-1 and EN 1992-1-2. BS EN 13224:2011EN 13224:2011 (E) 7 1 Scope This document identifies the requirements, the basic performance criteria and evaluation of conformity for precast ribbed elements made of reinforced or prestressed normal weight concrete, used in floors or roofs. The elements co
34、nsist of a top and/or bottom slab and one or more (usually two) ribs; transverse ribs may also be present. Some examples of precast elements considered in this document are shown in Annex A. Specific requirements for minor floor elements are listed in Annex B. This document covers terminology, perfo
35、rmance criteria, tolerances, relevant physical properties, test methods and aspects of transport and erection. This document does not cover load-bearing capacity determined by testing. 2 Normative references The following referenced documents are indispensable for the application of this document. F

40、 shall apply. For constituent materials of concrete EN 206-1 applies. In particular, the ultimate tensile and tensile yield strength of steel shall be considered. 4.2 Production requirements The production of precast ribbed elements shall comply with the requirements in EN 13369:2004, 4.2. NOTE In a
41、ddition to EN 13369:2004, 4.2.2 for cast-in-situ concrete considered to act compositely with precast units in the structural resistance (e.g. structural top layer), the minimum strength class is C 20/25. In particular, the compressive strength of concrete shall be considered. For minor floor element
42、s, strength classes shall comply with B.2.3. 4.3 Finished product requirements 4.3.1 Geometrical properties 4.3.1.1 Production tolerances Complementary to EN 13369:2004, 4.3.1.1 the following tolerances shall apply (Figure 1).

For minor floor elements according to Annex B, the permitted deviation on length is 25 mm. 4.3.1.2 Minimum dimensions EN 13369:2004, 4.3.1.2 shall apply. 4.3.1.3 Longitudinal connections If the precast units are connected
45、along their longitudinal edges by means of a cast in situ mortar or concrete joint, the minimum joint width shall be at least 30 mm at the top to allow satisfactory casting. The joint face shall be provided with at least one groove. The size shall be appropriate with regard to the shear resistance o
46、f the grout. If tie bars are to be anchored within the joint, the joint width at the tie bar level shall be at least three times the diameter of the bar to enable a satisfactory bond and a complete encasing of the bar. If welded connections are used, the connection devices should be designed in orde
47、r to allow an easy compensation of camber and erection deviations and welding execution.
