This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirem
23、ents of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Eurocodes are taken as a common reference for design aspects. This document was examined and agreed upon by a liaison ad-hoc group with CEN/TC 250, particularly for i
24、ts compatibility with structural Eurocodes. The installation of some structural precast concrete products is dealt with in EN 13670, Execution of concrete structures.

25、locks Part 3: Clay blocks Part 4: Expanded polystyrene blocks Part 5: Lightweight blocks for simple formwork (the present document) For common aspects of concrete products, reference is made to EN 13369, Common rules for precast concrete products, from which also the relevant requirements of EN 206-
26、1, Concrete Part 1: Specification, performance, 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. The program of standards for structural precast concrete products co
27、mprises 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 EN 13224, Precast concrete products Ribbed floor elements EN 13225

33、ns carried out in the factory. For design rules, reference is made to EN 1992-1-1. Additional complementary rules are provided where necessary. DIN EN 15037-5:2013-08 EN 15037-5:2013 (E) 7 1 Scope This European Standard deals with the requirements and the basic performance criteria for lightweight b
34、locks used as formwork during the construction of the floor system. The blocks are 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 systems. This European Standard does not deal with bloc
35、ks made in polystyrene, with or without tong, or combined with different materials where polystyrene contributes to more than 50 % of the mechanical resistance of the block. These blocks are covered by EN 15037-4, Precast concrete products Beam-and-block floor systems Part 4: Expanded polystyrene bl
36、ocks. Examples of typology of floor systems are given in Annex B of EN 15037-1:2008. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For u

41、rms and definitions apply. 3.1 lightweight block for simple formwork block with no mechanical function in the final floor system Note 1 to entry: Its only mechanical function is that of formwork during the construction of the floor system. Note 2 to entry: This block is mentioned in the present stan
42、dard as lightweight block. See Figure 1. DIN EN 15037-5:2013-08 EN 15037-5:2013 (E) 8 Figure 1 Examples of lightweight blocks 3.2 cut block lightweight block, the form of which is obtained by cutting 3.3 moulded block lightweight block formed by moulding, either by injection of the material in a mou
43、ld (injected blocks), or by pressing of the material in a mould (pressed block) 3.4 thin block lightweight block formed as a vault made of one or several layers of material 3.5 thick block lightweight block constituted by one or several materials, which forms a filled product 3.6 family group of pro
44、ducts for which the test results for one or more characteristics from any one product within the family are valid for all other products within the family Note 1 to entry: The definition of the family takes into account at least a same material and a similar shape and geometry. 3.7 batch quantity of
45、 lightweight blocks defined by either a same reference of raw material, or similar parameters and conditions of manufacturing, or manufactured during the same day of production (or 24 h in case of continuous production), without exceeding a length of 10 000 m 4 Requirements 4.1 Material requirements
46、 Only materials with established suitability shall be used. Lightweight block may be manufactured from: DIN EN 15037-5:2013-08 EN 15037-5:2013 (E) 9 a) wood material (plywood, fibreboards, Oriented Strand Board OSB); b) plastic material (polyethylene PE, polypropylene PP); c) cardboard, cellulose; d
47、) composite material (Glass Reinforced Plastic GRP); e) polymer concrete; f) metallic material; g) combination of the materials a) to f); h) one of the materials a) to f) combined with polystyrene, if this one contributes to not more than 50 % of the mechanical resistance of the block. For a particu
48、lar material, other than the ones mentioned above, the establishment of suitability may result from a European Standard which refers specifically to the use of this material for a similar use; in absence of a European Standard it may also result, under the same conditions, from an ISO standard. Where this material is not covered by a European or an International Standard, or if it deviates from the requirements of these standards,
