International

16、 and British Standards have been published to cover the specification of sizes for buildings, their components and materials, the system of tolerances for building and the requirements for joints and jointing in the design, manufacture and assembly of buildings. This British Standard is a combinatio

17、n of, and is technically equivalent to, ISO1006, ISO1040, ISO2848, ISO6511, ISO6512, ISO6513, and ISO6514, but incorporates minor differences in presentation. The “Specification” clauses of these ISO standards have been incorporated into the clauses of this standard. The “Application” clauses of the

18、se ISO standards have been incorporated into the appendix. BS6750 also takes into account ISO1790, ISO1791, ISO1803, ISO2444, ISO2445, ISO2776, ISO2777, ISO3443-1 and ISO3443-2. BS4011, BS4330, DD51, PD6432 and PD6444 are withdrawn. Further information on the subject can be found in CIB Report No.68

22、uction 0.1 The principle of modular coordination The principal purpose of modular coordination is to simplify and make more economical the design and construction of buildings, by standardization of sizes, in such a way that components fit with each other when assembled on site as parts of a buildin

23、g. Modular coordination is based on a standard reference system which uses the international basic module of100mm for the coordinated control of spaces in buildings, as well as for the sizing and locating of building components and elements. Modular coordination is a well established practical disci

24、pline which has been thoroughly proven over many years in many different constructions and circumstances, in most countries. 0.2 The need for modular coordination 0.2.1 General benefits. The principal effect of modular coordination is to facilitate cooperation between building designers, manufacture

25、rs, distributors and authorities; it provides a flexible type of standardization which encourages the use of building components having a restricted number of standard sizes for the construction of different types of buildings. Building components produced in standard ranges of sizes can be intercha

26、nged, whatever their form, material or method of manufacture. Site operations are simplified due to the rationalized sizing, setting out, positioning and assembly of building components. 0.2.2 Practical benefits in the design office. BS6750 specifies a framework that permits diversity of design thro

27、ugh the use of components having standardized modular sizes. The standard provides for interchangeability of components, which allows a flexible response to user requirements and individual needs. The standard also provides a basis for the systematic consideration of joint design to improve fit and

28、performance. Modular coordination is of particular significance in the light of the increased use of computers in design, costing and construction, where three dimensional coordinates are invariably needed in computer modelling to describe the location and size of spaces, elements and components and

29、 as a basis for the assessment, calculation and specification of their performance and costs. 0.2.3 Practical benefits in the manufacture of components. This standard specifies a way of sizing components to fit standard spaces in any building, and gives guidance on the selection of ranges of sizes t

30、hat will reduce variety yet increase potential applications by virtue of interchangeability. Adoption of a reduced range of selected standard sizes simplifies ordering of material, manufacturing processes, stock holding, invoicing, distribution and packing. 0.2.4 Practical benefits on the building s

31、ite. Adoption of the procedures specified in this standard will reduce waste on site arising from cutting to fit, accelerate the assembly process by ease of fit, and facilitate the coordination of the different trades and suppliers. Adoption will also ensure that equipment, services, storage units a

32、nd fitted furniture can be incorporated in the building in a coordinated manner. 0.2.5 Summary. Modular coordination makes use of: a) the basic module (i.e. 100mm); b) multimodules (see clauses2 and3); c) submodular increments (see clauses2 and5); d) a modular grid reference system to define zones a

33、nd coordinating spaces for building elements and for the components which form them; e) rules for locating building elements; f) rules for selecting preferred sizes for building components and coordinating sizes for buildings; g) rules for sizing building components; including their work sizes. 1 Sc

34、ope This British Standard specifies requirements for: a) modular reference systems to be used in the design of buildings; b) the position of key reference planes; c) the sizing of buildings and their components and materials which are designed in compliance with the principles of modular coordinatio

NOTEModular coordination terms occurring in the text may be found in the index.BS6750:1986 2 BSI 07-1999 3 Basic module The basic module sha

37、ll be the fundamental unit of size for the horizontal and vertical coordinating dimensions of buildings, their spaces, components and materials. The size of the basic module shall be100mm. The basic module shall be represented by the letterM. 4 Multimodules A multimodule shall be a selected whole mu

38、ltiple of the basic module. The sizes for multimodules shall be3M,6M,12M,15M, 30M and60M. NOTEMultimodules are used as increments both for the horizontal and vertical coordinating dimensions of buildings, their spaces, components and materials (seeTable 1). 5 Submodular increments Submodular increme

39、nts shall be selected fractions of the basic module. The submodular increment shall be either50mm or25mm. NOTEThe first preference for submodular increments is50mm and the second preference25mm. 6 Modular sizes for coordinating dimensions of spaces Sizes for horizontal coordinating dimensions of spa

40、ces shall be selected fromTable 2, and for vertical coordinating dimensions shall be selected fromTable 3. 7 Modular reference system The reference system for the design of buildings, the coordinated control of spaces in buildings, and the basis for sizing and location of components, shall be based

41、on a three dimensional modular space grid of100mm (seeFigure 1). NOTEThe principles of the reference system may also be applied to curvilinear and triangular structures.

Key reference planes shall be selected as datums for the location of components, and for practical setting out on site. A key reference plane used as a datum for setting out components shall be represented

49、 by a square set diagonally at the extremity of its line (seeA.5.4). 10 Modular floor plane Vertical dimensions shall be taken from the key reference plane. NOTEThe modular floor plane is the key reference plane. The modular floor plane shall be chosen from one of the following three positions. a) the upper surface of the floor covering seeFigure 3 and Figure 4(a); or b) the upper surface of the sub-floor seeFigure 3 and Figure 4(b); or c) the upper surface of the structural floor seeFigure 3 and Fi
