It supersedes BS 6492-2:1995 which is withdrawn. This edition is a full technical revision

9、of the standard reflecting changes in legislation, regulations and standards, particularly with regard to aspects of safety. The history of transportable accommodation is long and varied and can be traced back to the earliest nomadic tribes who carried, or used the backs of animals to move, their ha

10、bitation. Todays transportable accommodation units, developed as an alternative to huts and sectional buildings, are now accepted for a wide variety of uses, for which their specification and structural performance, installation and range of sizes, make them particularly suitable. Relocatable and tr

11、ansportable accommodation units are delivered ready for immediate use. Units without wheels may either be craned, fork-lifted or winched into position or off-loaded from a flat-bed truck by one person using a telescopic jack-leg system. They may be linked end to end, side by side or end to side, or

12、stacked to form a two or more storey structure. Since the 1960s, transportable accommodation units have been manufactured in large numbers under factory controlled conditions. The volume and diversity of their manufacture has made it desirable to standardize the basic shell which is covered in part

13、1 of BS 6767. This part 2 of BS 6767 caters for the use of a transportable accommodation unit. It gives recommendations for the design and installation of services, partitions, stairways, steps and equipment. It also includes guidance on fire precautions, legislation, transportation, handling, sitin

14、g and use in climatic conditions. The extent to which units are required to conform to legislation depends upon their use, some ranking as permanent buildings and therefore being covered by building regulations. In drafting this part of BS 6767 the Technical Committee has been mainly concerned with

15、giving recommendations on the installation of services, fixtures and fittings and the selection of units for use on sites with differing characteristics and limitations, and with giving guidance on the transportation and handling of units. Attention is drawn to the fact that transportable accommodat

16、ion units are often located on congested sites and are used together in multiple configurations either adjoining one another horizontally or by being stacked vertically. In the interests of occupant safety, recommendations are given for safety requirements, durability and stability in a variety of u

17、ses, configurations and locations. It has been assumed in the drafting of this standard that the execution of its recommendations and provisions is entrusted to appropriately qualified and experienced people. A British Standard does not purport to include all necessary provisions of a contract. User

18、s of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. In particular, attention is drawn to: Building Regulations 1991 1 Building Standards (Scotland) Regulations 1990 2 Building Regulations

22、ices, partitions, stairways, steps, ramps, links, units used for storage and equipment in transportable accommodation units. It gives guidance on legislation, fire precautions, transportation, handling, siting, climatic exposure, environmental considerations, foundations and anchoring, and the inspe

23、ction and maintenance of the units with particular reference to aspects of safety in use. These recommendations are intended for use by designers, manufacturers, suppliers, installers and purchasers of transportable accommodation units.

37、his part of BS 6767 the definitions given in BS 6767-1 apply together with the following. 3.1 link unit structure designed to interconnect two transportable accommodation units horizontally 3.2 configuration arrangement of transportable accommodation units relative to other units or other structures

38、 3.3 foundation construction to transmit dead and imposed loads from a transportable accommodation unit to the supporting ground 3.4 final exit end of an escape route from a transportable accommodation unit which provides direct access to a street, passageway, walkway or open space, and positioned t

39、o ensure the rapid dispersal of persons from the vicinity so that they are no longer in danger from fire and/or smoke 4 Legislation 4.1 General 4.1.1 The legislation applicable to a unit is determined by its siting, occupation and use. This applies particularly to units used as offices, shops and ot

40、her purposes where the public is admitted or people are employed. Such units could come within the scope of the relevant Building Regulations 1,2,3, the Town and Country Planning Act 1990 17, Town and Country Planning (Scotland) Act 1997 18, the Planning (Northern Ireland) Order 1991 19, Health and

41、Safety at Work etc. Act 1974 11 and the Fire Precautions Act 1971 9 and regulations made under section 12 of that Act, such as the Fire Certificates (Special Premises) Regulations 1976 21. Units covered by this legislation may require special construction and surface finishes differing from those re

42、commended by BS 6767-1. 4.1.2 There should be early consultation with the appropriate authorities before agreeing details of a specification with a manufacturer or supplier. 4.1.3 The design, handling, siting, linking and removal of units from site are subject to the Construction (Design and Managem

43、ent) Regulations 1994 22. Appropriate responsibilities and duties need to be established prior to commencement of work. 4.2 Change of use For each unit it is important to know its type of construction and surface finish when considering its suitability for a different use. The consultation recommend

44、ed in 4.1.2 should be held when the use of a unit is to be changed. 5 Installation and connection of services 5.1 General 5.1.1 Where services are required, provisions should be made on the unit for their connection and they should conform to relevant British Standards. NOTE Attention is drawn to th

45、e recommendations given in 5.2 to 5.6. 5.1.2 Cables and pipework should avoid the structural framework and foundations, unless these are designed to accommodate them. It is essential that the manufacturer of the unit states where service entry and exit points are located. 5.1.3 Adequate sleeving sho

46、uld be provided where the shell of the unit is penetrated by services. Resulting gaps should be sealed to prevent the entry of insects and animals and to prevent draughts and deterioration. 5.1.4 All services, connections and mountings should be adequately secured to withstand impact and vibration d

47、uring transportation and in normal use. 5.1.5 An accessible means of isolating gas, electricity, oil and water services should be provided near to their points of entry and marked accordingly. 5.1.6 The local authority should be consulted regarding local regulations and requirements applicable to th

48、e supply of services to transportable accommodation units. 5.1.7 All service installations fitted by the manufacturer should be factory inspection tested and certified prior to despatch. 5.1.8 Where pipe work and fittings protrude externally, their effect on the overall dimensions of the unit (see 1

49、0.3) and the necessary clearances between the unit and the transporter should be taken into account. 5.2 Electricity 5.2.1 Installations Electrical installations should conform to BS 7671. No transportable unit should be connected on site to electricity unless the manufacturers declared values of prospective short circuit current and earth loop impedance are compatible with those of the supply, the bonding arrangements are suitable, and the supply can safely provide the maximum demand of the
