The documentation for such prefab
23、ricated components includes drawings, specifications and schedules. This International Standard deals only with drawings. NOTE 1Specifications and schedules may be prepared as separate documents, or as additional information on the drawing sheet. 2 Normative references The following standards contai

27、s 3.1.1 Production drawings for (moulded and non-moulded) prefabricated structural components shall define the shape and composition of the components. They shall be fully dimensioned and shall provide all the information necessary for the manufacture, inspection and further handling of the componen
28、ts, such as a) designations of the components, b) reinforcement, c) surface requirements, d) built-in parts, holes, recesses and grooves, e) provisions for easy removal from the mould, and f) safety devices for lifting, and provisions for handling, transportation and storage. 3.1.2 The drawings shal
29、l be executed in accordance with the relevant International Standards. 3.1.3 Preferred sheet sizes shall be chosen from those given in ISO 5457. 3.1.4 The preferred scales, in accordance with ISO5455, are the following: a) main views and sections: 1 : 50, 1 : 20, 1 : 10; b) details: 1 : 20, 1 : 10,
30、1 : 5, 1 : 2, 1 : 1. 3.1.5 Views and sections shall be represented in accordance with the method using reference arrows as specified in ISO 128. 3.1.6 Dimensioning from a common origin is preferred. Circular recesses and holes shall be dimensioned to their centre line, and rectangular recesses and h
31、oles to their edges. 3.1.7 General tolerances are usually given in the specifications. If it is necessary to indicate special tolerances, these shall be indicated on the relevant figures and in accordance with ISO 6284. 3.2 Designation 3.2.1 The designation of the components shall be clearly indicat
32、ed on the drawing, preferably in the title block. If more than one component is shown on one drawing, the designation(s) shall be adjacent to the main figure of the relevant component. 3.2.2 When the component requires marks for orientation or location in the structure, the space for and the form of
33、 these marks shall be indicated on the drawing as shown in Figure 1. 3.3 Reinforcement Reinforcement shall be indicated in accordance with ISO 3766. Figure 1 Example of indication of a location mark with reference to a detail drawingENISO 7437:1996 4 BSI 11-1998 3.4 Surface requirements Requirements
34、 for the surface finish are usually given in the specification. The boundary of surfaces which require special treatment shall be indicated on the drawing by a thick chain line as shown in Figure 2. 3.5 Built-in parts Built-in parts shall be precisely indicated on the drawing, if necessary by detail
35、 drawings, or by reference to a specification, a catalogue number, a type number, etc. 3.6 Provisions for easy removal from the mould 3.6.1 Provisions affecting the shape of the component shall be indicated and dimensioned on the drawing. 3.6.2 Other provisions for easy removal from the mould or for
36、 protection of the component are usually given in a specification. 3.7 Safety devices for lifting, and provisions for handling, transportation and storage 3.7.1 The positions where slings or other lifting or supporting devices may be applied directly to the component shall be shown on the drawing, f
37、or example by a simplified representation of the component in a smaller scale, as shown in Figure 3. The location and extent of these positions shall be indicated by dimensions with tolerances (see 3.1.7). 3.7.2 If it is necessary to mark the lifting and supporting positions on the component, the me
38、ans of marking shall be explained on the drawing or in a specification. 3.7.3 Requirements for transportation and storage shall be given in a specification.
