Magnetic levels in construction

Is it possible to build a house with curved walls, ceilings and floors? Of course, you can, somewhere in Africa, the natives do so. After all, wild tribes do not use the usual construction tools and, even more so, modern horizontal and vertical control devices. Yes, they do not need it. But an ordinary European person can not live in a building with overhanging walls, skewed slopes and crevices in the doors - it's ugly, uncomfortable and impractical. In addition, such a dwelling threatens to collapse on the head of its unlucky owner and forever hide from descendants "amazing habitation skills."

To prevent this from happening, it is still worth sticking to the basic canons of construction and using such a useful tool as a level or plumb line. Moreover, they are not at all difficult to use and require only care and patience. Even if the construction is not expected, the level is indispensable in the economy: to hang a picture exactly, to put a gas stove in the kitchen or a washing machine - all this will help to do it without any problems, saving time.

The modern construction industry produces levels of different configurations, technical equipment and designations. The assortment is so wide that a novice builder can easily get confused when choosing a tool for himself. In fact, there is nothing complicated here. There are three main types of building levels: water, bubble and laser. All the variety that we see on the shelves of stores, is represented by modifications of these basic models. The so-called magnetic levels are just an improved form of ordinary bubble.

What is the level: the principle of action

The building level is a device with which you can control the position of the building elements with respect to the vertical and horizontal lines and to each other. It is also convenient with it to specify a certain angle of inclination, if required by the design.

The principle of operation of this tool is based on the physical phenomenon of gravity and the property of fluid to occupy in space an exact horizontal position in a calm state. This can be visually observed by filling a glass jar with water. As much as we do not have a capacity in space, the water will tend to align horizontally.

Now let's take two transparent vessels, connect them with a flexible hose (according to the principle of communicating) and fill with liquid - that's the hydro level. Fill the test tube for the chemical experiments with water, leaving a small air bubble, plug it with a stopper and set it horizontally - you will get a bubble level.

Assignment of the main types of levels

As described above, the main types are water, bubble, laser level indicators and plumb bobs. All of them are used for specific types of construction work.

The plumb line. With the help of it, it is convenient to control the vertical, for example, with forcing the wall. Rope and special cargo - that's all the details of this device. The load is suspended on a rope, it is fixed at the top point of the finished wall and the rows of masonry are corrected if the line is littered with respect to the reference vertical. To work with a plumb line you need a trained eye of the builder.

The laser level type appeared relatively recently and gained wide popularity. It looks like a tripod with a floating head attached to it. The latter always occupies a horizontal position in space. The head is equipped with a laser emitting a color beam. It is a reference horizontal or vertical line, relative to which work is performed. The laser magnetic level is a slightly different design. Its base contains a magnet that is simply applied to vertically mounted metal racks or a wall.

The water level. It serves to draw a zero mark relative to which this or that kind of work will be done, for example, a screed device, lining the ceiling, fixing the first row of tiles, etc. To work such a device, two people are needed: one holds the original bulb at the mark, the second Exposes all other points. The level must be properly filled with water, preventing the formation of air bubbles inside the tube.

Bubble type of the level detector. The so-called masonry level, which is used by bricklayers, erecting walls. Also it has wide application in the device of any skeletons, in plaster works and many more where. It is a hollow profile pipe made of light metal, into which are inserted mini-flasks with a liquid and an air bubble. This bubble is a level indicator. Usually there are three such flasks: for horizontal direction, vertical and at an angle of 45º.

Magnetic levels: where they are applied

The kind of construction level from the bubble series, where magnets are included in the design, was called the "magnetic level indicator". This tool was specially developed for the installation of metal frame building elements. It is convenient to use them when welding square tubes and fixing various metal profiles. Also, all construction operations where a conventional bubble level is applied can be performed with this device.

Magnetic levels have the following characteristics:

1. Do not require fixing the hands to a controlled surface of metal.
2. Highly accurate and versatile.
3. Can be performed as an electronic magnetic level or with an integrated laser emitter.

How to check the magnetic level for accuracy?

Buying from the seller a level of building magnetic, does not prevent to make sure of its accuracy. To do this, directly in the store, you must select a flat horizontal surface and put the tool on it. The middle of the position, which took the bubble, should be noted with a thin marker. Further on the same place just also put the level, only turn it to 180º. A vial on a working instrument should take the same position.

Similarly, check the correctness of the vertical level indicator. Do not take the defective tool in the hope that you can correct it a little. Indicators are exhibited at special factory stands. At home, this can not be repeated.

How to use the magnetic level?

When welding, use the magnetic level as follows:

1. The metal part is applied to the installation site and seized by welding so that it can easily be bent to the sides.
2. Attach the magnetic level to the part and bend it until it takes the desired position.
3. Carefully fix by welding.

Conclusion

Due to the fact that in modern construction technologies steel frame structures of buildings are often used, the magnetic levels have been developed at the right time. Supplying them with electronic indicators with backlighting greatly facilitated the use of this tool, significantly weakening the load on the human visual organs.
