Levels of construction: description, types and verification

Building levels are used for gaugingtilt horizontal and vertical surfaces. With the help of these tools, marking is made for the construction of all kinds of structures, furniture assembly, application or stowage of finishing materials. Neither construction nor repair can not do without a level.

To determine the choice of the tool, let's first understand what kinds of levels exist.

First of all, this is the water level. Its other name is the hydro level. It is used in those cases when it is necessary to find irregularities in the arrangement of horizontal surfaces. his work is based on the main feature of the water surface: always take the same position - horizontal.

Hydraulic level is a sleeve, lengthwhich can be from five centimeters to several meters, at the ends there are flasks with a microcascal applied. Levels of construction of this kind have both pluses and minuses.

The advantage is their simplicity in operation andlow price, and the downside is that you can use such a tool, working only with horizontal planes. Do not store it near a radiator. Water in the sleeve should not have bubbles, otherwise the readings will be erroneous.

Most often, masters use bubble-type building levels. Such a device consists of a housing in which flasks with a liquid are arranged.

If there is only one flask in the level,It determines the error of only horizontal planes, with two bulbs - both horizontal and vertical. If the flasks are three, then such a device determines also the value of the turning level. Usually bubble levels are rectangular. Their length can be from 20 centimeters to 2.5 meters, and telescopic models - up to four meters.

Often newcomers are interested in how long the building level should be. 2 meters and less - that's the optimal size.

The body of the level is usually made of polystyrene or from light metals, for example aluminum. The liquid in the flasks is alcohol.

There is a commercially available subspecies of bubble levelstype - magnetic. This is a bubble tool, only with magnetic inserts. It is very convenient if you work with metal, as it is easily attached to metal surfaces.

Did you find in the store what you need? And how to check the level of construction? Everything is very simple.

Place the tool on a flat plane. This position should be noted, so that later on the same place put the second test tool. At the level there are divisions, so the bubble will most likely shift to one of them. We must remember to which. Turning the level, we put it on the old place, which we noted a little earlier. If the bubble "leaves" in the same direction as it deviated last time, then the level works perfectly. If not, continue to choose.

Recently, on the shelves of constructionmarket appeared laser levels of construction. These are very accurate tools, but they have a drawback - it's their cost. If accuracy is above everything, such a device is what you need. Accuracy provides a laser beam, whose length can reach up to one hundred meters.
