Fire protection drawing identification method
(1) Fire fighting drawings are divided into fire fighting water, fire fighting electricity and gas fire fighting;
(2) No matter what it is, any drawing must first look at the design description and legend;
(3) The design description is the outline of the drawing, and the design intention and content can be grasped through reading;
(4) Different designs may have different legends;
(5) Then there is the system diagram, which is the catalogue of a book. You will know the working state and connection mode of his whole system after reading it.
(6) Finally, the plan is a further refinement of the system diagram, indicating the installation mode, location and connection mode of the equipment;
(7) Note: When reading drawings, the plan and system drawings should be compared to contact the whole system.
Look at the fire protection drawings, how can you understand them at a glance?
Fire engineering drawings are generally divided into drainage (automatic sprinkler, fire hydrant, gas fire extinguishing) and electrical (automatic fire alarm), and some construction companies will also let fire companies do smoke prevention. The fire budget is classified by specialty, and the specific equipment installation cost can be found in the fire installation quota.
(1) such as nozzles, spray pipes, supports and hangers, fire hydrants, alarm valves, probes, modules, alarm equipment, etc. , other general parts set the corresponding professional quota.
(2) For example, the quota of water supply and drainage pipeline of fire hydrant pipeline, industrial pipeline of pump house, mechanical equipment quota of fire pump, industrial pipeline quota of valve flange, electrical installation quota of line pipeline at alarm position, etc.
(3) Material algorithm: The number of equipment shall be improved by itself according to the number of drawings.
