6、 foreword This standard has been prepared by Technical Committee CEN/TC 229 “Precast concrete products” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was the Normenausschuss Bauwesen (Building and Civil Engineering Standards Committee), Working Committee NA 00
7、5-07-08 AA Betonfertigteile (SpA CEN/TC 229). This document includes EN 15037-2:2009 and Amendment A1:2011. However, due to a number of errors, the 2009 version of this standard was not published in Germany. These errors are now corrected by Amendment A1:2011 which includes further updates of Clause
8、s 4, 5 and Annex ZA. Amendments This standard differs from DIN 4158:1978-05 as follows: a) concrete blocks are now harmonized at the European level; b) conditions for CE marking have been established; c) Amendment 1:2011 has been incorporated; d) the normative reference to EN 771-3 has been updated;
9、 e) the subclauses relating to the test report and interpretation of test results have been revised.

The European Standard for beam-and-block floor system is made of 5 parts: EN 15037-1, Precast concrete products Beam-and-block floor systems Part 1: Beams; EN 15037-2, Precast concrete products Beam-and-block floor systems Part 2: Concrete blocks; EN 15037-3, Precast concrete products B
29、eam-and-block floor systems Part 3: Clay blocks; !EN 15037-4“, Precast concrete products Beam-and-block floor systems Part 4: Polystyrene blocks; prEN 15037-5, Precast concrete products Beam-and-block floor systems Part 5: Lightweight blocks. This European Standard is one of a series of product stan
30、dards for precast concrete products. 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
31、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 Execution of concrete structures. In all countries it can be accompanied by alternatives for national application.“ The
32、 program of standards for structural precast concrete products comprises the following standards, in some cases consisting on several parts: DIN EN 15037-2:2011-07 EN 15037-2:2009+A1:2011 (E) 5 EN 1168, Precast concrete products Hollow core slabs EN 12794, Precast concrete products Foundation piles

35、and-block floor systems Part 1: Beams EN 15050, Precast concrete products Bridge elements EN 15258, Precast concrete products Retaining wall elements This European Standard defines in Annex ZA the application methods of CE marking to products designed using the relevant EN Eurocodes (EN 1992-1-1:200
36、4 and EN 1992-1-2:2004). 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. According to
37、 the CEN/CENELEC Internal Regulations, 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, Lat

39、lied 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. DIN EN 15037-2:2011-07 EN 15037-2:2009+A1:2011 (E) 7 1 Scope This European Standard deals with
40、the requirements and the basic performance criteria for blocks made in normal or lightweight aggregate concrete, 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 and roof systems. Example
41、s of typology of floor and roof systems are given in Annex B of EN 15037-1:2008. 2 Normative references The following referenced documents are indispensable for the application of this document.

However, its top flange alone cannot act as a compression slab in the fin
