32、ical stress level - HIGH: stresses in non-residential rooms - NORMAL: stresses in residential rooms 4 Design 4.1 General By following the recommendations in this document, the designer can specify partitions suitable for the use for which they are intended. 4.2 Materials gypsum blocks according to E
33、N 12859; gypsum-based adhesives for gypsum blocks according to EN 12860; other materials and accessories can be used. 4.3 Structure and Functions 4.3.1 General The following factors can influence the choice of the type of gypsum blocks and shall be taken into account with the structural requirements
34、: a) type of building (single-family houses, buildings, etc.), purpose (accommodation, schools, offices, hospitals, etc.) and use (for example: damp rooms); Licensed Copy: London South Bank University, London South Bank University, Fri Nov 16 07:55:10 GMT+00:00 2007, Uncontrolled Copy, (c) BSI EN 15
35、318:2007 (E) 7 b) dimensional accuracy of the structure; c) service arrangements (distribution of fluids, electricity); d) type of connections to the structure and to the incorporated elements (frames, etc.), fixing loads. The following functions shall also be taken into account in the choice of the
36、 type of gypsum blocks: e) exposure to impacts and abrasion; f) temperature and humidity conditions; g) thermal insulation; h) sound insulation; i) safety in the event of fire. 4.3.2 Dividing or separating partitions The partitions ensure one or more of the following functions: Separation, fire prot
37、ection, sound insulation or thermal insulation, supporting of loads, impact strength. 4.3.3 Backing partitions Backings are structures intended to reinforce the thermal insulation, sound insulation or fire resistance properties of the structures against which they are backed. 4.3.4 Ducts The ducts e
38、nsure one or more of the following functions: protecting the ambient medium against noise generated or transmitted by the shafts; protecting the shafts against fire; preventing propagation of the fire from one room to another. Vertical ducts can be made of gypsum blocks on one or more faces accordin
39、g to their positioning relative to the shell construction. The duct walls can be single or composite according to the performance required. 4.3.5 Lining of posts For aesthetic or technical reasons (fire resistance), all types of post (wood, metal, concrete ) can be protected by gypsum block structur
40、es. 4.4 Specific structural requirements 4.4.1 General Depending on the type of building or purposes of the rooms, special precautions shall be taken into account. 4.4.2 Damp rooms In rooms exposed intermittently to water, either by use or by the need to wash the surface of the partition or the adja
41、cent floor, water-repellent gypsum blocks shall be used. Licensed Copy: London South Bank University, London South Bank University, Fri Nov 16 07:55:10 GMT+00:00 2007, Uncontrolled Copy, (c) BSI EN 15318:2007 (E) 8 The type of blocks is determined depending on the planned use of the room and on the
42、level of exposure of the wall to water. 4.4.3 Walls exposed to impacts In rooms where a higher surface resistance is required with respect to impacts (e.g. schools, corridors ), it is recommended to use high-density blocks in the areas involved. 4.4.4 Safety in the event of fire Where the structure
43、is considered to meet fire resistance requirements, it shall have been the subject of a test and a classification according to EN 13501-2. The blocks can also be selected as a function of the fire resistance values in use specified in 4.5.2.2, Table 1. 4.4.5 Protection against noise Where the struct
44、ure is considered to meet sound insulation requirements, the blocks are selected as a function of the information in 4.5.5. 4.4.6 Overhanging partitions Special provisions shall be made to improve the safety conditions in use. 4.5 Requirements 4.5.1 Mechanical strength and stability Gypsum block par
45、titions are self-supporting non-loadbearing structures that do not affect the general stability of the structure. The mechanical requirements linked to safety in use are covered in 4.5.3. 4.5.2 Fire behaviour 4.5.2.1 Reaction to fire Gypsum blocks conforming to EN 12859 are classed as Euroclass A1 (
46、non-combustible) without testing when they contain less than 1% by volume or by mass (according to the most unfavourable value regarding reaction to fire) of homogeneously distributed organic material. If they contain more than 1 % of organic material by mass or by volume, they shall be tested and c
47、lassified according to EN 13501-1. 4.5.2.2 Fire resistance a) Fire resistance of single partitions The values in use established in previous tests to be confirmed or determined subsequently on the basis of EN 1364-1 are given in Table 1.
