It is impossible to imagine modern construction without accurate measurements at all its stages, from laying the foundation to finishing finishing work inside the rebuilt buildings. The use of the latest measuring tools allows you to accurately and easily make the necessary measurements to exclude possible mistakes and a construction marriage. Special devices are in demand that determine the difference in the height of two points removed from each other, – levels. Different types of these devices differ in the type of design and the principle of operation.
Most often, builders use the most advanced devices that form a beam visible to the eye. The simplicity and convenience of working with a laser level is explained by its constructive features. Rays formed by a laser emitter pass through an optical prism or focusing lens, creating perfectly even planes or straight lines, focusing on which the necessary surfaces and angles are aligned.
The most popular, during construction work, leveling using laser rays forming two even, intersecting in the space of the plane. Devices of this type are useful when installing the screed of bulk floors, stretch ceilings, leveling walls and doorways, laying facing tiles. This principle of working with a laser level is called static or positional leveling.
If the measuring device creates a bright point with the subsequent turning of it into an even line between the laser device and the surface, then this is the rotational type of leveling. Usually it is used when pasting surfaces with wallpaper, installing skirting boards and other repair and finishing work.
Despite the accuracy and high productivity of the device, the conduct of various kinds of measuring works with a laser level does not require special technical training of construction workers. The tool has a special constructive node – a compensator that automatically supports the mobile optical axis in the necessary position without interference and control of a specialist. This approach increases the reliability of the data obtained, excludes errors and saves the working time of the performers.
However, working with a laser level requires compliance with certain rules dictated by the features of the device. In order to avoid the negative action of the laser, effective protection of vision is necessary. It should also be taken into account that in the rays of bright sunlight, the ray of laser levels becomes invisible, so it is better to use it in rooms and in the shade.
