No. This British Standard, having been prepared under the direction of the Sector Committee for Building and Civil Engineering, was published under the authority of the Standards Com
3、mittee and comes into effect on 15 November 1999 Date Comments O BSI 11-1999 ISBN O 580 32838 4 National foreword This British Standard is the English language version of EN 1065:1998. The UK participation in its preparation was enirusted by Technical Committee B/514, Access and support equipment, t
4、o Subcommittee B/514/28, Props, tubes and couplers, which has the responsibility to: - aid enquirers to understand the text; - present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; - monitor related internation
5、al and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. This British Standard, together with BS 40741999 (in course preparation), will supersede BS 40741982, and partially supersede BS 550731982
6、 which is currently under revision. The revised edition of BS 5507-3 will descibe methods of determining the characteristic resistance of dustable props not conforming to BS EN 1065. BS 40741999 covers steel trench struts. This standard provides the user with a greatly enlarged choice of props. It i
7、s recommended, therefore, in the interests of maximizing site utilization, length compatibility with existing props, and as an aid to economic prop manufacture, that users should give preferential consideration to sizes 25,30,35,40 and 50 in either B or C strength grades and to either F2 or F4 corro
8、sion protection methods. Additionally, the use of loose forkheads is recommended. It is recommended that, if a pin has any reduction in its nominal cross section (such as holes for cables or chains), a means should be provided to ensure that this portion of the pin is always outside the collar nut m
9、ajor diameter. The principal changes from BS 40741982 and points of significance are as follows: a) Steel trench struts (previously known as trench struts) are not covered. b) Advice on safe working loads is not included. It is envisaged that the next amendment to BS 5975 will contain some advice. c
10、) Five different strength classes of props are included. Identification is now given by marking on each prop the number of the standard, the name or trademark of the manufacturer, the year of manufacture, the classification, and the props compatibility with EN 74 couplers. The prop may also have the
11、 classification identified by profiling the endplates. When required (see annex E) the level of inspection and/or the sign of the independent certification system also have to be marked. d) Five methods of corrosion protection are given. e) Props are classified according to their fully extended leng
12、ths which range from 2,5 m to 5,5 m in 0,5 m intervals. Fully closed lengths of props are no longer specified but all props have at least 1,0 m of adjustment. f, Props having a fully closed height of less than 1,5 m are no longer included. g) A test to venfy that the component parts of dustable tele
13、scopic steel props do not become inadvertently disengaged in use has been added. h) There is a minimum linear clearance of 100 mm between the inner and outer tubes intended to form an anti-hand trapping gap when the prop is in the fully closed position. i) The minimum permissible end plate bearing a
14、rea is reduced. j) A maximum clearance between threads is now specified. k) There is a minimum material thickness for ali prop components. 1) The use of rimming steel is no longer permitted. m) Geometric designed props are no longer included. n) Verification of the nominal characteristic resistance
15、of an individual prop design may also be by calculation. o) Information about independent prototype assessment is included in annex D.

30、 Committee CENTTC 53, Temporary works equipment, the Secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 1999, and conflicting national standards shall be wi
31、thdrawn at the latest by March 1999. According to the CENCENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy,
32、Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Introduction Whilst this European Standard deals with the more common types of adjustable telescopic steel props in use, it is not intended to prevent development of other types of props. For example, props
33、 may have hinged ends or other length adjustment devices or be made of other materials Whilst such props cannot comply with this European Standard it is recommended that the principles of this European Standard be considered in the design and assessment of such props. The characteristic strength val
34、ues specified in this European Standard form a reference level which is unsafe for direct site use. It is a matter for a separate European Standard to relate these characteristic strengths to safe site usage by applying suitable partial safety factors yu and yF. It is also a matter for a separate Eu
35、ropean Standard to specify the required level of corrosion protection and inspection. This European Standard is a product standard primarily for use in the field of falsework and formwork. In cases where the prop is an integral part of a system of soffit support, other design and assessment procedur
36、es may be more appropriate or even necessary. This European Standard gives a number of alternatives, a designation of which is given in clause 5. 1 Scope This European Standard specifies materials, design requirements, corrosion protection alternatives together with assessment methods using both cal
37、culations and testing for open thread and covered thread adjustable telescopic steel props which are intended for use on construction sites (see Figure 1). It specifies five classes of nominal characteristic strengths for adjustable telescopic steel props each having a series of maximum extended len
38、gths. Each having differing endplate configuration. This European Standard does not apply to adjustable props of different materials or construction, nor does it provide any information concerning the use of adjustable steel props.
