After reading the drawings and Atlas for so many years, we are still unfamiliar with some uncommon drawing component codes! After so many years of civil engineering, the mechanical and electrical professional drawings are still very important

.

In fact, the difficulty of professional drawings lies in the complex code

.

Today, I present you the most complete collection of drawing codes! 👉 Mysterious “rich second generation”, real identity from the bottom! Code name of common building components board B roof truss WJ roof panel WB bracket TJ hollow slab KB skylight frame CJ trough plate CB frame kJ folded plate ZB rigid frame GJ ribbed plate MB bracket ZJ stair slab TB column Z cover plate or trench cover plate GB frame column KZ rain shield plate or cornice plate Yb constructional column GZ crane safety walkway board DB concealed column AZ wall board QB bearing platform CT gutter slab TGB foundation J beam L equipment foundation SJ roof beam WL pile zh crane Beam DL retaining wall DQ monorail crane beam DDL trench DG rail connection DGL support between columns ZC car stop CD vertical support CC ring beam QL horizontal support SC lintel GL ladder t connecting beam ll awning YP foundation beam JL balcony YT stair beam TL beam pad LD frame beam KL embedded part M-FRAME beam KZL skylight end wall TD roof frame beam WKl steel mesh w purlin LT steel skeleton g professional drawing code complete code code indicates SC steel pipe pcpvc polyethylene flame retardant Plastic pipe CT bridge WC is laid along the wall in a concealed way WS is laid along the wall in a concealed way CC is laid along the roof in a concealed way f is laid in a concealed way CE is laid along the roof in a concealed way YJV cable SYV TV line PE grounding (yellow and green) pen connecting to neutral (blue) 3 line (live line) a (yellow) B (green) C (red) kV (voltage) kV scattered line MEB total equipotential LEB local equipotential line laying method code PVC laying with flame retardant plastic pipe DGL laying with electrical steel pipe VXG laying Plastic trunking laying GXG with metal trunking laying KRG with flexible plastic pipe laying line open laying position code LM along roof truss or lower chord of roof truss laying ZM along column laying QM along wall laying PL along ceiling laying line concealed laying position code La concealed in beam Za concealed in column QA concealed in wall PA concealed in roof or ceiling Da concealed in floor or floor PNA concealed in ceiling Installation method code D ceiling type L chain type G pipe type B wall mounted type R embedded br marking method of distribution lines installed in the wall A-B (C × d) e-fa represents circuit number B represents wire model C represents wire number d represents wire section e represents laying method and pipe diameter f represents laying position 2 wires represents 3 wires represents n wires marking method a Number B model or number C lamp number per lamp, D bulb capacity, We lamp installation height, MF installation mode L light source type, incandescent lamp or fluorescent lamp construction engineering official account number recommended long, click below 2D code to identify attention.
