Levels and plumb lines are traditionally used to determine the degree of evenness and the deviation of erected structural elements. The operation of both devices is based on the principle of gravitational gravity, which causes the cable with the sinker to be placed strictly vertically, and the air bubble pointing to the middle of the scale to demonstrate a strictly horizontal position. However, such a familiar and at first glance reliable tool still gives some error. So, the bubble level, even the best, according to passport data has a maximum deviation of 5 mm for every 10 m, but in reality the situation is somewhat worse.
Moreover, in some cases it is not enough to simply outline certain lines along which a building or structure will be erected. Builders need a tool that allows them to visualize the position of the planes in space.
Working with a laser level is much easier. This device creates visible lines displayed on the walls, and if necessary, then on the floor or ceiling, on which it is very easy to make markings. Some samples are equipped with several optical prisms, which makes it possible to see the corresponding number of vertical, horizontal or inclined levels simultaneously.
Before using the level, you should familiarize yourself with the instructions for its use. By the way the marks are displayed, they are divided into linear, point and combined. The rotational module included in the design makes it possible to rotate the "head" around the axis, and thus it is possible to represent the entire plane and its intersection with other surfaces.
The tasks to be solved with the help of beam marking are varied, they indicate the lines of passage of communications, the location of partitions, water and sewer pipes, and make it possible to control the verticality or horizontalness of already mounted structural elements, especially during multi-story construction. Initially, they were conceived for indoor work.
The question arises of how to use the level on the street or an open construction site, in bright daylight, which complicates the visual fixation of the laser beam mark. To solve this problem, special radiation detectors are used, which are part of the design of the device. Before they were invented, the outdoor use of this equipment was limited to the point version, the light lines were poorly visible.
Builders sometimes have a question about
how to use a laser level as a plumb line. It is also possible, because the capabilities of the device are determined by the number of rays, and many models are equipped with this function. As a rule, there are no more than four vertical rays, which makes it possible to build two planes, since the construction of one of them requires two rays. However, there are models in the construction of which there is a special prism that gives a linear image due to the refraction of a signal from one source. In any case, the capabilities of the device are the wider the more rays it has, although, of course, its price directly depends on this parameter.
There are also features in how to use the level, depending on the type of its body. They are flat and round. Each of the types has its own advantages and disadvantages. Round levels have a swivel base, and are often equipped with a function for measuring angles, but flat can be placed close to the wall.
The self-leveling function and other useful options make working with plane builders very simple, it does not require special skills to operate this technique, any builder will quickly figure out how to use the level.
