How to read construction drawings
First determine the scale of the drawing. As a rule, they have clearly structured values. So, for example, plans, facades and cuts are made on a scale of 1:50, 1: 100, 1: 200. Basement sections are usually executed on a scale of 1 to 50, and the details of the structures in the figure are depicted 1: 5, 1:10, 1:20 and 1:50. Floor plans and rafters are given a scale of 1 to 100. But the wiring diagrams are usually correlated with the real ones as 1 to 100 or 1 to 200. When deciphering the dimensions, remember that they are all in millimeters, and the elevations of the facades and cuts are in meters.
Reading the drawing, note that the floor plan is displayed as a horizontal cut. And it passes necessarily through the window and door openings. Also on the plan you can see the grid of the center axes. They are designated in the following directions: those that run along the front wall are in Arabic numerals; those which are located on the side - in capital letters of the Russian alphabet.
If you see that some designations are beyond the dimensions of the plan, then they, as a rule, denote the distance between the extreme center axes; the distance between the center axes attached to the outer edges of the wall; binding of walls to center axes, as well as dimensions of walls and openings. All that is within the plan is a binding of the internal walls and partitions to the center axes; the thickness of the walls and partitions, as well as the dimensions of the openings in the internal walls and partitions; the size of the holes in the ceiling. Remember that the sum of the dimensions for each section can be easily calculated by the length of the wall. She is equal to her.
The projections of the building, which can be viewed from the front, and behind, and to the right, and to the left of the vertical plane - this is the facade. The numbers taken out of its contour in the drawing denote elevations from ground level. If you see the axes of the walls or columns in the drawing of the facade, this will help you determine which type of facade is depicted in this diagram. It is possible to determine from the cuts in the diagram which building dimensions are between the outermost axes, what the ground level is, the distance from the floor to the floor, the dimensions of the openings, the height of the openings, marks where the stairs should be.
The drawing of the house on the plot will allow you to determine how you can plan the use of the plot, where to make the entrances and approaches to the house, how you can plant trees and trees on the territory. If you want to bring these ideas into the drawing, then you will need to calculate them precisely by the standards of the scheme and then place them on the drawn area, of course, observing the required scale.
