What do you think of plumbing drawings?

Question 1: How to read the plumbing installation drawings? Be sure to look at the plan and system diagram, so as to know where the pipeline turns, where it changes diameter, where the water distribution point is and what the elevation of the water distribution point is. When looking at water supply, we must see whether there are corresponding drainage measures and water facilities, and then consider whether the water supply points, drainage measures and water facilities are reasonable. If there is a water supply point designed for laundry room residents, in general, the elevation of the water supply point is 1. 1m from the finished floor (depending on the design), and then it depends on whether there are washing machine drainage floor drains, special floor drains for washing machines and traps. These all depend on whether the washing machine has a power socket, whether the location is reasonable, whether the socket is safe and whether there are safety measures. Ink painting must have a strong three-dimensional sense, to achieve the feeling that you are standing in the room and following the pipeline.

First, look at the electrical drawings and instructions: how high the socket is installed, whether the height meets the safety requirements, where the distribution box is installed, what is the load, whether it is reasonable, whether the opening size is reasonable, how big the outlet protection tube is, whether the wires are reasonably matched, whether the wires are reasonably matched with electrical equipment, and how to lay the conduit. In lightning protection grounding, it depends on whether the "connection diagram" and "lightning protection diagram" of the down lead position correspond. If not, where will it be converted? What level of lightning protection does lightning protection belong to? Whether the size of lightning protection network is within the specification range, the material and size of down lead, the material and specification of steel bar lap, and more importantly, whether there is an equalizing ring on the top floor to prevent side lightning strike, local equipotential in the bathroom, grounding effect of grounding soil, local water level and geological conditions. Although many of these designs should be considered, if we want to look at the hydropower diagram and go deep, we have to examine the rationality and practicability of the design in turn.

Combined with civil engineering, we can see the hydropower diagram, whether the size of structural beam, the size of embedded casing is reasonable, what is the building elevation, and whether the service height of the room is affected after the installation of hydropower facilities. Room size, wall size, raft thickness, leveling layer thickness, insulation is internal or external insulation, insulation layer thickness, interior and exterior wall decoration layer thickness, these data can be accurately embedded, reserved and made.

Water, electricity, heating, ventilation, air conditioning and other drawings need to be read together, so as to have a global awareness, ensure that no items can be missed, and ensure the accuracy of calculation. For example, some electrical connections need to see the installation height of the equipment before they can be calculated in place.

There is another important place to know the drawings. Where the drawings are not shown, you must look at the construction atlas, so that you can see the parts that are not shown in the drawings.

Question 2: How to read plumbing drawings? Look at the plan first. There are lines on the drawing, such as lights, fire fighting and water supply pipes. Look at the legend and you will know what equipment this thing is. Look at the system diagram again. At this time, it is necessary to combine plans from time to time. It is also necessary to combine the actual wiring on site, and how to connect the light wires will definitely be known when you actually do it. It is unrealistic to think out of thin air. Experience is the mother of wisdom.

Question 3: How to read the plumbing drawings? In the drawing, the top is north, the bottom is south, the left is east, and the right is west. It is very important to look at the first few pages of the drawing before looking at the location of each pipeline in the drawing.

Question 5: How to read the plumbing drawings? According to the classification of drawings, first look at architectural drawings, and then look at professional drawings. For water heating and ventilation drawings, we should look at the system diagram first, and then look at the plan.

Question 6: How to read building plumbing drawings? If it is a real estate developed by a more formal developer, after the house is completed, a set of information will be handed over to the property management company. You just need to go to the property company and wait for a note explaining the reason, and you can find it in the property company.

If it is an informal developer, not equipped with property, or an old residential area, you can only go to the local urban construction archives for consultation, and ask the local urban construction archives for specific supporting documents.

Question 7: How can we learn to read the drawings of water, electricity and warmth? Drawings with strong knowledge of plumbing and electricity are also careless.

Of course, this is a comparison with civil engineering.

My temporary solution is to do the indoor work of water heating and electrical appliances, and take the drawings corresponding to the actual situation of on-site construction, and I will know it slowly.

Question 8: How to identify drawings in cad? For example, several simple methods such as pipelines. The first is to look at the drawing tab (if any), which generally has a professional description or a description of the drawing name; The second is to look at the design instructions; The third is to look at the main expression content of the drawings, generally thick lines highlight the specialty.

Question 9: How to learn to look at the drawings in the direction of building installation, water heating and electricity, and go to school to study professionally; Read some books on this subject and learn from them; Ask someone else to teach you.

It won't take you long to learn.

Question 10: symbols of pipeline engineering drawings. The symbols of pipeline engineering drawings include check valves, single valves, ball valves, gate valves, butterfly valves, tees, elbows and large and small heads.

There are connectors, radiators, sub-cylinders, boilers, pumps, thermometers, pressure gauges, water level monitors, safety valves, sewage valves, slag removers, exhaust fans, air supply fans and so on. That's about it. You can read the drawing according to its description.
