Simple pay off method to find right angles Is there any other algorithm besides 3,4,5?

There is another way, as long as the Pythagorean theorem is satisfied.

The sum of the squares of the two right-angled edges is equal to the hypotenuse.

Square is sufficient. 3'4'5'It was a shortcut to facilitate calculation in the previous period when there was no calculator, and now the calculator and mobile phone functions are so popular, as long as it is convenient for any data can be used to put the wire.

It can be used to measure the diagonal line of the house.

method. Most houses, whether single or as a whole, are rectangular or composed of multiple rectangles.

The characteristics of the rectangle: the diagonal lines are equal, and the four corners are right angles.

That is to say, if the four corners are 90 degrees, the figure must be rectangular, then the diagonals must be equal, and conversely, if the diagonals are not equal, it must not be a rectangle, so the angle of the corner of the house must not be 90 degrees.

In the acceptance of the project, when there is a doubt about whether the corner of a room is 90 degrees, the method of measuring the diagonal is generally adopted.

In the construction industry, there is a professional term that is to set off the line to find the right angle, maybe some people are not engaged in the construction industry, and they do not know much about it. In fact, when building a house, it is the most basic job to find the right angle of the line. And an experienced technical worker will have a lot of magic branch methods when setting off the line to find a right angle, we can learn a little about it, let's take a look at it together.

1. If it is a self-built house, how to put the line to find the right angle.

Many rural houses need to be put out at the beginning of construction, which is the most important step for the future construction. If the current line is not done well, then the built house may not be 90 degrees, and it will have a great impact on the structure of the house.

A method that has been circulated since ancient times, and it is still in use until now, if it is a rural house building, this method is actually more practical.

In general, when a house is first built, the foundation is dug in the shape of a rectangle, and then the workers insert four poles at the four points of the rectangle. After that, we can use a long wire to connect them to make sure that the four corners are all 90 degrees, which we can correct with a ruler or with the help of a tape measure. Then you can put the lime line, which can ensure that the line is at a right angle.

Second, if you are building a high-rise building, how to put the line to find the right angle.

If it is a high-rise building, the requirements will be very strict, and the method of building a house in the countryside cannot be used to find a right angle, so we need to use an instrument, to use a professional theodolite, and use this instrument to pay off the line, which can ensure accuracy.

Generally speaking, if the area of the building is relatively large, the height has reached a certain standard, it is necessary to use the theodolite to pay off, its advantage is more accurate, but the disadvantage is that it is relatively slow, to move the instrument at any time to determine the vertical line.

Nowadays, at the beginning of the construction of many houses, professional technicians must be positioned according to the theodolite, so as to determine the accuracy of the pay-off.

3. What aspects need to be paid attention to when laying out the line.

1. Pay-off work is a technical job, and workers can only operate it with a job certificate.

2. Before pay-off, the design plan should be determined according to the construction site and the surrounding environment.

<> as shown in the figure, if b + c = a , then the triangle abc is a right triangle, and the common combination is 6, 8, 10 in addition to 3, 4, 5; 5,12,13；9,12,15；12, 16, 20 and so on.

For self-built houses, pay-off is the first step in construction, which is very important, and it is necessary to ensure accuracy and leveling to ensure that all angles of the house are accurate 90-degree right angles, but because the geographical conditions of self-built houses are relatively special, the difficulty of construction will be greater. So, what are the methods of simple pay-off to find right angles? What should I pay attention to when building a house in rural areas?

Let's take a brief look at it together.

1. What are the methods of simple pay-off to find right angles?

You can use the principle of hook three strands and four to calculate an accurate 90-degree right angle; Alternatively, you can use a ruler to slowly frame the angle of the line until it becomes an accurate 90-degree right angle. Note that the pay-off must first set the horizontal point, and in the adjustment process, the mu type should not be moved, and after all the right angles are adjusted, they should also be reviewed and inspected to ensure the accuracy of the right angles.

2. What should be paid attention to in rural self-built houses?

1. Pay attention to the application for building a house: the countryside is a self-built house, which seems to be very simple, but in fact, the application process is more troublesome, first of all, you must have your own homestead, and then you must pass the review of the Land Bureau, or the planning permit, before you can start building a house.

2. Pay attention to house design: now self-built houses, there are many different types and styles, for many young owners, minimalist decoration is very popular, simple and elegant, but the design is more complex, you must find a professional designer.

3. Pay attention to the indoor layout: usually the area of the self-built house will be relatively large, and at least two floors can be built, pay attention to the separation of movement and static when layout, to ensure the comfort of life, but if there are elderly people at home, pay attention to the design of a bedroom on the first floor, easy to use.

4. Pay attention to the size of the house: because the land in the rural areas is relatively spacious, many owners will enclose a large piece of land in front of them for their own use in order to facilitate their own use.

Summary: The above methods for simple pay-off to find right angles, as well as what need to be paid attention to in rural self-built houses, are introduced here, I hope it will help you. If you want to know more about related information, please pay attention to Qeeka Home.

<> as shown in the figure, if b + c = a , then the triangle abc is a right triangle, and the common combination is 6, 8, 10 in addition to 3, 4, 5; 5,12,13；9,12,15；12, 16, 20 and so on.

Use a hook three strands to four strings five.

The method is to determine an axis first, find a right-angle point, and tighten the three sides with a thinner line, respectively, with a length of three, four, and five, and the unit can be unified, and there is a triangle with a straight angle.

A right angle point can be released when the right angle edge coincides with a known point in the field. The bigger the triangle, the bigger.

Accurate, of course there are instruments better.

A theodolite is also required.

Take the measurements to know. The measurement angle can be closed, and then measured, and after calculation, the accuracy reaches the allowable error range, and the result is known.

After the building positioning pile is set, the professional surveyors of the construction unit and the construction site are used.

The person in charge and the supervisor jointly release the foundation project.

and measurement review (the supervisor is mainly the side station supervision and verification).

Finally, the positioning piles of all building axes are released (according to the size of the building, the axis can also be spaced apart), and all axis positioning piles are laid out according to the positioning piles (at least 4) of the planning department and the construction plan of the ground floor of the building. The pay-off tool is "theodolite".

Pay-off tools: theodolite, gantry panel, wire rope, line pendant, steel tape measure, etc. Small projects may not have a surveyor, that is, the construction worker will pay off the line.

As long as it is an odd number, it can constitute a proof:

Odd k*k=2n+1

So (2n+1)=(n+1) 2-n 2, so k 2+n 2=(n+1) 2

For example: (1 0 1) (3,4,5),(5,12,13)(7,24,25)(9,40,41).

As long as it is the number of Pythagoreans, it can be used to pay off the line to find the right angle.
