How to set beacons for floor screed? Selection of beacons depending on the method of leveling the floor
Gradually, the time of curves disappears from our liveswalls, ceilings and floors. Today, the owners of housing in various ways go to leveling the lines in their apartments and houses, the floor here plays the most important role. It is from the floor that the general horizontal of the room will be "drawn". In order for it to be even, a screed with leveling points is often used - so-called beacons, if properly installed, the floor is smooth and perfectly even. How to set up beacons for floor screeding independently, without attracting highly paid specialists in this field - a difficult question, but solvable ...
Types of screeds
Construction practice suggests that in different conditions and requirements originating from the customer of the floor, there may be different types of screeds. At the moment, there are three main types:
- Dry screed. It is often used to level the insulation from claydite, on top of which a "wet" screed will be produced.
- Screed concrete, cement-mortar and dry. The most popular form today, used in the process of building new premises and repairing old ones.
- Screed from the filling floor. A relatively new type, in which special self-leveling mortars are used.
Tip: the choice of beacons for floor screeds should be made based on the type of future coverage.
Lighthouses used for dry and semi-dry screed
For this type of floor leveling, most masters use the usual profile, used in the installation of the frame of walls for gypsum board. However, there are at least two ways of installing beacons:
- The first is that the beacons are stacked on a low mound of the building mix, and then with the help of the rule and level the necessary plane is reached.
- The essence of the second method is that forLevel settings use self-tapping screws and dowel-pliers screwed into the floor base. First, the two ends are screwed in, after which the thread is tightened, then every 30 cm it is necessary to screw in the missing threads. The profile for beacons for floor screeds is installed over self-tapping screws and in several places it is fixed with a construction mixture.
Tip: if you use gypsum mixes for fixing, you can start the basic work in a few hours. When using cement slurry will have to wait at least a day, or even more (depending on the brand of cement), until the solution seizes.
Types of lighthouses for semi-dry cement-sand and concrete screeds
This kind of screed is the most popular nowadays both among professionals and among the people. Its mass character can be explained by two factors:
- Materials for the preparation of the building mixture are available for the average citizen, and everyone interested in self-repair knows them. It's cement and sand.
- The technology of performing the work is quite simple. Any person who started repairs in his apartment will cope with it.
The difference between lighthouses can be made from materials,used for their manufacture: specialized, from solution, profile, steel pipe and wood. At once it is necessary to say that the first kind of lighthouses is cheap, but very much "plays", so its installation requires more time and perseverance than all the others. The question of how to set up beacons for floor screeding and correctly produce them on their own is set by many novice self-builders. However, after studying all the nuances of this process, it is quite possible to do it yourself.
A very convenient method that allows you to quicklyset the floor level in the room. Undoubtedly plus pipes - strength, the beacon will not "play". Minus is a high cost, but if you fill repeatedly and in large volumes, this option has a place to be. At the beginning and end of the pipe piles of thick solution are poured, a pipe is laid on them and the height at the beginning and the end of the room is regulated with the help of a water level.
Advice: it is preferable to use a pipe (it is rectangular), since smooth faces are more convenient than round pipes when leveling.
Beacon from a profile installed in a solution
All you need to do is cooksolution (thicker), lay a mound in the direction from the far wall to the exit, install on it a U-shaped metal profile in an inverted state. The solution can be used on the basis of gypsum or cement.
Tip 1: Professionals recommend using the same material for beacons to be used for the whole screed, otherwise premature damage to the fill may occur.
Tip 2: the gypsum base under the beacon will dry for a couple of hours, cement-sandy - for a day or more, which will have to wait more time.
Beacon from a profile mounted on self-tapping screws
This type of leveling is one of themost used. Its essence lies in the fact that to the base of the floor are attached small brusochki with facets about 1.5 cm and lengths up to 15 cm, fastening is made through 25-30 cm. After that, it is necessary to screw in self-tapping screws (first extremely, then medium ones) using a chopstick for this purpose. Further all is simple - the U-shaped metal profile used for a frame of walls from a plasterboard is taken, and it is established over self-tapping screws. The lighthouse is ready!
Lighthouse from solution
In this form, only a solution is needed. The initial stage is similar to the first method - a thick solution is laid out with a knoll, then the level is pulled by a chop thread or a colored fishing line, then the hill is leveled at a fixed level. After drying, the beacon can be used for its intended purpose.
Tip:This type of beacon is, first, a relative (ideally flat line is almost impossible to achieve). Secondly, at this level, when pouring, it will be difficult to slide the rule. As a result, in the places where the lighthouse passes, various kinds of "goose bumps" will appear.
Lighthouses from wooden bars
Metal profile in the construction appearedquite recently. As for the pouring of the floor, it was used in ancient times and during the Soviet era. Then in the form of beacons wooden bars were used. Their disadvantage is that, firstly, it is rather difficult to find perfectly smooth products, and secondly, when dried, they can deform.
Tip: Before you put beacons to screed the floor from the bar, it should be well soaked, otherwise the bar may adversely affect the quality of the screed.
There is also the existence of combiningseveral kinds of materials. The bottom line is that a dowel-pair is driven through the meter to the bottom of the floor. Screws are screwed into them. The void between the dowels is filled with a solution.
Advice: the solution level should be higher than the self-tapping screws, since in the future it is necessary to take the rail (or profile) and press the composition to the same level with the screws.
Lighthouse used for semi-dry screed
Some folk craftsmen, for the first time tryingthis kind of filling, are interested in the answer to the question: "How to set up beacons for floor screed from a semi-dry solution?" When using this method, some masters generally dispense with the usual lighthouses and work only on certain landmarks.
To do this, lay out smalla pile of mortar, after which, at one level, they form, as it were, platforms - they will act as landmarks for the future screed. After the pads have solidified, you can lay out a semi-dry solution and fill the distance between the landmarks.
Tip: it is desirable to use this type of lighthouses in small rooms, since the width of the rule should "cover" the entire distance between the sites.
Lighthouse for "floating screed"
In some cases, a conventional substrate based onfloor for insulation is not enough, and builders use as an additional insulation layer of foam. In this case, the coupler in the people is called "floating". The best version of the lighthouse in this case will be on self-tapping screws. Initially, installation of self-tapping screws is made taking into account the thickness of the insulation in the floor base according to the level, then a layer of foam plastic is laid (it is necessary to pierce it at the locations of the beacons).
Tip: after installing lighthouses for floor screeding with your own hands, you should unscrew the screws and fill the voids with a solution.
Lighthouses for bulk floors
Recently, the market has appearedself-leveling mortars. According to the manufacturers, to carry out the screed of this material, the need for lighthouses is no longer necessary. Professionals do not advise to neglect the leveling. In the role of a beacon, special tripods are used - benchmarks that are installed on the basis of the floor. Their undoubted advantage is that the height is regulated by a simple turn on the hourly arrow or against. Their minus is a relatively high price.
Instead of benchmarks, you can use conventional screws, which after pouring are removed from the solution.
Tip: You should set rappers or screws at a distance of 1 meter from each other.
Do I need to remove beacons from the floor screed?
In order to answer this question,it is necessary, at least in general terms, to have an idea of the behavior of various materials with varying temperature and humidity. From the school course of physics, everyone knows that liquids, metals and gases are heated when heated, and, when the temperature is lowered, they contract. And you need to take into account the fact that each chemical element varies in different ways. This also applies to changes in humidity. For example, a raw bar can be thicker than 1 cm dried.
Proceeding from this, it can be understood that the screedit must be monolithic - of the same material. Therefore, all foreign objects (bar, profile, pipe, screws) must be removed. In addition, the metal has a high sound conductivity, which is also undesirable in conditions of living in high-rise buildings. Therefore, after the question of how to set up beacons for floor screeding and all the work is done, the moment of withdrawal follows.
Flat floors are half of a good repair.Floor and ceiling give the main lines of visual perception of the room. That is why the interest of professionals and craftspeople appears to this issue. In summary, it's safe to say that any skilled worker, having studied the above process, can easily determine which beacons for floor screeding will be preferred in certain conditions and what nuances must be remembered when carrying out work.
