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

This European Standard is one of a ser

27、ies of product standards 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

28、 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 Execution of concrete structures. In all countries it can be accompanied by alternatives for nationa

37、pean Standard deals with 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

38、and roof systems. Examples 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.
