Steel Structural Plan Drawing Conventions

Drawing Conventions and Representations

Construction drawings communicate how something is congenital by showing specific assemblies and by employing architectural drawing conventions. These conventions are adequately standard throughout the manufacture and are used to reduce the drawing fourth dimension and infinite needed to convey information. For example, in Effigy 5-xvi, a graphic symbol with an arrow drawn on a cabinetry department denotes the exact place the section was cutting and the direction of the view taken in the resulting section cartoon.

Abbreviations, graphic symbols, keys, and legends are used as shorthand to reduce drawing fourth dimension while carrying of import information. Another convention governs how dimensions are recorded in a drawing. Dimensioning standards ensure that exact sizes and placement of assemblies are communicated by using a system that is recognized past both the designer and the builder.

Abbreviations

Abbreviations for words and short phrases are often used in construction drawings. Usually used abbreviations can be found in the Appendix, but it should exist noted they are not universal. Abbreviations can vary among the different trades, as, for instance, QT can mean "quarry tile" or "quart." The architect, engineer, interior designer, drafter, and contractor must all exist able to recognize what each abridgement stands for. The drafter should include a legend of abbreviations (often shown on the title sheet of a set up of drawings) to ensure their meaning is understood. Encounter Effigy v-17

Graphic Symbols

Graphic symbols are used in construction drawings as a pictorial shorthand to reduce drawing time and coordinate divide drawings. For example, symbols can be used on a flooring-plan drawing to indicate placement and type of specific equipment such as electric outlets and wall calorie-free switches (Effigy 5-18). Although symbols may vary from part to office, there are generally accustomed types used by all architectural and interior blueprint firms. Each symbol must communicate clearly specific directives to exist followed.

Symbols are divided into several types: material symbols, line symbols, graphic symbols, and component symbols.

Material symbols are used in drawings to stand for the structure materials used in a component. Designers should use the symbols well-nigh widely accepted in the manufacture, such every bit those shown in Effigy five-19, indicating materials cut in department. Symbols are also used to indicate materials in summit drawings, every bit illustrated in Figure 5-xx. A detailed list of materials and their section symbols is shown in the Appendix.

Line symbols use the graphic look, line weight, and thickness of elements represented in the drawings to communicate information

to the viewer. For example, a dashed line can indicate a subconscious feature or object. Come across Figure v-21 for typical line symbols and their meanings.

Graphic symbols can be used to index related parts of drawings, either on the same sheet or multiple sheets. Letters, numbers, and notes can be placed within the symbol to organize it with other symbols and refer to other sheet numbers. Symbols tin can also be used to denote a specific height on a floor elevation or structural column designation. These basic symbols are shown in Figure 5-22. See a more complete listing of symbols in the Appendix.

Legends

Construction drawing legends combine graphic symbols with notes. They are used on a multifariousness of drawings, such as flooring plans, furniture plans, electrical plans, and lighting plans. For instance, a wall legend (Figure 5-23) tin can exist used on a floor programme to designate a specific wall construction assembly. An electrical fable is used
