DIN EN 16508:2016-02 EN 16508:2015 (E) 4 Introduction The purpose of a temporary roof and encapsulation construction according to this standard is to protect the area inside from climatic influences and dust. It is also used to pr
20、otect the public from effects from inside. This European Standard includes rules for structural design, which are of particular relevance to encapsulations. Individual countries may have national laws or regulations which are not in line with this European standard. Information on that can be found
21、in the attached A-deviations. DIN EN 16508:2016-02 EN 16508:2015 (E) 5 1 Scope This European Standard specifies performance requirements and design methods for temporary roofs and encapsulations. It is possible to form the constructions in several ways: temporary roof which is supported by an existi
22、ng permanent construction (Figure 1); temporary roof which is supported by a scaffold (Figure 2 and 3); temporary roof which is supported by another temporary construction (e.g. steel frame); temporary wall which is supported by a separate construction (Figure 4); encapsulation which is a complete t
23、emporary construction including roof, walls and corresponding temporary supports (Figure 5). This European Standard sets out general requirements. These are substantially independent of the materials of which the construction is made. This standard is intended to be used as the basis for enquiry and
24、 design. 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 undated references, the latest edition of the referenced document (including
25、any amendments) applies.

27、purposes of this document the terms of EN 12811-1 and EN 12812 and the following apply. 3.1 temporary roof construction intended to cover work activities DIN EN 16508:2016-02 EN 16508:2015 (E) 6 3.2 temporary encapsulation construction intended to encapsulate work activity areas, consisting of a com
28、bination of following elements: roof, walls and supports Note 1 to entry: For different types, see Figures 1 to 5.

30、nstruction including roof, walls and supports 3.3 kentledge material attached to or placed on a structure to provide stability by the action of its dead weight 3.4 support structure which is to withstand the imposed effects from the construction 3.5 sheeting/cladding flexible or stiff component, nor
31、mally intended to provide protection from climatic influences and/or dust protection 4 Materials Materials shall fulfil the requirements given in European Standards, where design data are provided. If European Standards do not exist, ISO Standards may be applied. This European standard is not intend
32、ed to prevent the use of existing components made of materials in accordance with standards that were valid at the time of their introduction. Materials shall be sufficiently robust and durable to withstand normal working conditions. Materials shall be free from any impurities and defects, which may
33、 affect their satisfactory use. Additional requirements for some materials are given in EN 12811-2. This European standard does not intend to prevent the use of non-standardized materials. When materials are used, whose properties in relation to the intended application (e.g. temperature, ageing, UV
34、-degradation) are not given in any available standard, an adequate assessment according to relevant national regulations is required. If walking on the sheeting is permitted by the supplier of the encapsulation, then it shall be able to withstand the appropriate actions. DIN EN 16508:2016-02 EN 1650
35、8:2015 (E) 9 NOTE Material requirements for some sheeting are given in EN 13782. 5 General requirements 5.1 General The components shall be designed so they can be safely erected, used, maintained and dismantled. Attention shall be paid to ergonomic considerations. 5.2 Access Safe and ergonomic mean
36、s of access to all areas within the encapsulation and to the temporary roof shall be provided when appropriate. The access should preferably be by means of stairways. Access shall be according to the requirements of EN 12811-1. NOTE Access to the temporary roof could be required for repair, opening
37、or snow clearance. 5.3 Openings If necessary, for the purpose of lifting in equipment or materials, it should be possible to remove parts of the structure temporarily. These parts shall be secured when removed. 5.4 Moveable structures Moveable structures shall be secured against uplift at all times.
38、 If such securing is not possible, a maximum wind speed for loosening and moving shall be stated. 6 Classification of snow/minimum load classes Encapsulations are classified in snow load classes according to Table 1. Exceptions to the snow load classes may be decided by national regulations. Table 1
39、 Snow load classes Snow load class Guidance Load kN/m2SL 1 No snow load (Minimum load) 0,1 SL 2a Based upon snow clearance management a0,25 SL 2b Based upon snow clearance management a0,6 SL 3 Site specific snow load in accordance with EN 19911-3 NOTE See also national annexes. aSnow clearance manag
40、ement may be achieved by physical removal, heating, etc. 7 Structural design 7.1 General Each encapsulation, including all its parts, shall be designed, constructed and maintained to ensure that it does not collapse or move unintentionally and so that it can be used safely. This applies at all stage
41、s, including erection, modification and until fully dismantled. The designer shall have access to all relevant design data from the supplier of prefabricated equipment. DIN EN 16508:2016-02 EN 16508:2015 (E) 10 The forces determined for the loading capacity and stability proof for temporary roofs an
42、d encapsulations shall be taken into consideration in regard to the external supporting structure. 7.2 Support An encapsulation shall have support capable of resisting the design loads and limiting movement. 7.3 Method of design The structure shall be designed in accordance with recognized engineeri
43、ng principles. The design shall take into account the variability of materials, workmanship, site conditions and construction tolerances. The structure shall be designed with regard to ease and safety of erection and dismantling. The designers shall provide guidance on the implementation of their de
44、sign. If not specified otherwise, the design should be carried out following the ultimate limit state (ULS), including load bearing capacity, stability against sliding laterally, overturning and uplift. Design shall be carried out in accordance with the European Standards for structural engineering,
45、 including their respective national Annexes. The current standards include: For design: EN 1990 For actions: EN 1991 For steel: EN 1993 For timber: EN 1995 For aluminium: EN 1999 If there are conflicts between provisions in this standard and other standards, e.g. ENs, then the provisions in this st
46、andard shall have precedence. The encapsulation shall be designed by taking the effects of the complete structure into account. The design of a scaffold as support of a temporary roof shall be carried out in accordance with EN 12811-1 considering the safety factors defined in 7.6 with taking into ac
47、count the additional effects from the temporary roof, see Figure 3. 7.4 Actions 7.4.1 General Typical actions on encapsulations are described in the following sub-clauses. The values Q1to Q8are characteristic values of actions. Where appropriate for a specific project, account shall be taken of othe
48、r loading conditions with load combination according to EN 1990. NOTE Loads from specific projects may come from lifting equipment, lighting etc. 7.4.2 Permanent actions, Q1The permanent action “self-weight” shall be taken into account. Self-weight includes: the encapsulation structure; kentledge; o
49、ther dead loads (e.g. suspended working platforms, lifting beams, lighting etc.). DIN EN 16508:2016-02 EN 16508:2015 (E) 11 7.4.3 Variable imposed actions, Q2 Q47.4.3.1 General The designer shall consider which combinations of the variable loads are favourable or unfavourable for the structure. 7.4.3.2 Access and service load, Q2All access and service loadings on scaffolding elements shall be taken from EN 12811-1. 7.4.3.3 Other imposed loads
