Hydroelectric drawings how to see the small drawings contain the university asked

Water and electricity, I think this is the two essential elements of our family. Electricity is the source of energy for our appliances. Water is a necessity for our lives. Therefore, the construction of hydropower in our home is a prerequisite to protect our good living environment. We must be cautious and strict in the beginning of the renovation. After the designer completes the design drawing, there is no problem with the consultation. When the construction is completed, it will be done according to the construction drawing. But one thing is: What do you think of the hydropower drawings ? The hydropower construction map is not something that we can read at random, but we need to use it to understand it. Here I will give you a detailed introduction to the relevant knowledge of water and electricity drawings .

How to look at the drawings

Look at the drawings necessary work:

For example, if we want to understand classical Chinese, we must first learn to read and read drawings. The symbol of various components will generally appear on the drawing sheet. We need to sort out the meaning represented by these symbols in a short time.

Second, it is necessary to learn to understand the structure of drawings. When we find out the characteristics represented by each form of drawing, we can easily figure out the meaning of this drawing. In this way, the errors in the drawings can also be checked.

  

Five steps to teach you to read drawings

1. Before reading the drawings, we need to read the design specifications, and then look at the drawings after preparing the relevant standards and specifications, so that we can understand the overall plan.

2. If it is a construction drawing, then we need to take the drawings to the site, compare the relevant atlases prepared before, calculate the axis distance in the drawings, and then mark the important configuration with other colored pens. In this way, we can clearly distinguish the relationship between drawings and objects in the field. If some of the buildings are unclear, you can ask the construction staff on site to sort out their order.

3. Look at the structure of the facilities in the drawings. Mark each code of the wall column and floor in the order according to the sequence, and then calculate the ratio of size to the size of the drawing.

4. Take a comprehensive look at the plan, perspective, and section of the construction site, compare the site settings, and clearly indicate where the three-dimensional changes have occurred. In this way, things that are difficult to understand on the drawings will be understood more than half of them.

5. Finally, check and check again, and mark the shortcomings of the construction on the drawings. With this, we can easily understand a drawing.

  

How to look at water and electricity drawings

The first is the construction of water

When we look at the water drawings, we try to look at the floor plans and renderings that designers give us so that we can imagine where the flow pipes turn and where they change their caliber based on floor plans. It also depends on whether the location of the water distribution point meets our own needs. Whether the water supply point is arranging drainage points and water facilities at the same time, and whether the relationship between the three are reasonable and whether they can meet their own needs. If the design shows that there is a floor drain in the washing machine, then we must ask whether the floor drain for the washing machine is installed and whether the location of the outlet is reasonable.

When looking at the water construction plan, we try to establish a three-dimensional concept of space, start looking at the entrance to the water pipe, and imagine that we are standing in our room and following the pipeline. If you do not understand or are not satisfied with the place you can contact the designer or design company to negotiate and resolve.

Then the electric construction drawing

Looking at the construction drawings of electricity, we must first understand the height of the electrical outlet and whether the height has reached the corresponding requirements for safe electricity use. Where are the total distribution box locations and where are the distribution box installation locations? What is the maximum load, the diameter of the wire protection tube, the reasonableness of the wire, and so on, all require our high attention. Then, to see where the location of the lightning protection lead of the building is, and whether the location of the downline originally marked is the same as the level of the lightning protection, and whether it is in line with the lightning protection requirement level in this area. As well as the bathroom's electrical map and so on. (The bathroom needs special materials for circuit use due to its function. It must be made of water-proof and moisture-proof materials.) These are all we must find and carefully verify.

Editor's summary: Drawings are actually not very difficult to understand. If you look at books in the architectural category and practice a lot, you can easily overcome this problem. If you want to read the drawings, you often observe them on the construction site. Comparing the three-dimensional graphics outlined on the drawings with the plane graphics and the construction construction, you can understand most of them. Sometimes you will see some special symbols. If you can't remember, you can ask the person present. In this way, a drawing can be easily read, but it is still impossible to memorize it.
