In construction, during installation, repair or finishing work, one cannot do without the use of a special tool – a level. The level allows you to determine the strict correspondence of horizontal and vertical directions.
How to use the laser level
The old spirit level (construction water-bubble level) and the rope plumb line were replaced by a modern construction tool – a laser level.
Varieties of levels
According to their functional properties, laser levels are defined by three types:
dotted
Prismatic
Rotary
The point level emits a narrow beam, projecting a point onto the surface. It is mainly used when carrying out minor repairs at home. Install interior details on the same level, arrange furniture or make holes in opposite walls.
Prism level projects perpendicular lines, beam dispersion along the axes reaches 120°. It is indispensable in the production of finishing works, wall plastering, tiling, wallpapering.
The rotary level projects lines in two perpendicular planes due to the rotation of the beams by 360°.
How to use the laser level
Crossing lines are visible simultaneously on the floor, ceiling and all walls of the room. Rotating lasers have a powerful radiation that allows you to see the beam at a distance of several hundred meters. They are convenient to use in large rooms, when designing partitions and the simultaneous work of several people.
Powerful radiation allows them to be used as levels on construction sites, determining the height difference on the site. When laying communication lines, setting foundation levels, erecting walls.
For any kind of laser levels, there are several general rules:
Never forget safety. The laser beam, if it hits the retina directly, can damage it and cause blindness. Special goggles must be used to protect the eyes.
Before starting work, the functionality of the device and the battery charge are checked. To do this, turn it on by pointing at the wall. In no case looking into the hole from which the beam comes out.
The device must be securely fixed at the required height. Each model of the device has its own devices for fixing at the desired level. This can be a tripod, tripod, fixtures for mounting on a wall or pipeline
Preparation for work
Installed and fixed at the required height, the device is leveled in a horizontal plane.
How to use the laser level
For this, each device has adjusting screws and bubble indicators. In simple devices of laser levels, it is necessary to achieve the most accurate horizontal position, combining bubbles in indicators, until the desired mark.
In devices with an automatic setting level, the horizontal position can be installed not so accurately. Automation eliminates errors within 10 ° deviations from the horizon level. Automation of two types, electronic and pendulum, which operate on the principle of a gyroscope is located in devices. The automation fixer is disconnected on the displayed device, leveling will be aligned within a few seconds, and the sound or light signal will notify the readiness of the device for work.
An example of work
The basis of all work is the leveling of the floor and determination of the zero level. For this, the laser level is set at an altitude of about one meter. Along the perimeter of the entire room, measurements from the laser strip are made to the base plate. The largest indicator is taken as the zero level, all vertical calculations are already made from it.
If there is a need to work in inclined planes, then the automation is turned off by fixing, and the device is installed at the required angle.
Some models can project multiple horizontal and vertical stripes, as well as the simultaneous designation of points on the ceiling and floor.
When choosing a laser level, it is necessary to be guided for what types of work it will be used, and the conditions for its operation.
