It is the vibration screed for laying concrete that makes this coating extremely durable and high-quality.
The concrete coating itself has a huge number of advantages.
However, in order for it to really have high technical characteristics, it must be poured according to all the rules of the existing technology.
It is correct to prepare the mortar and put the shuttering in only half the way, the concrete must be correctly and correctly laid.
If after desiccation inside the concrete base there are airborne areas and voids, this coating will most likely not last for a long time and will lose much in quality.
Therefore it is very important in the process of pouring cement mortar, to carry out its thorough compacting and compaction. This will release the air that got there, and thus remove the voids.
This work can be done manually, by piercing a fresh solution with a piece of reinforcement, but no one guarantees the quality of such concrete, and even with a large pouring area it will not be easy and quite problematic.
In order to simplify the work and make the coating of the highest quality, and use a universal screed for concrete, which you can buy, and you can do at home with your own hands.

Principle and Basics of Operation
In general, a concrete screeder is a special aggregate consisting of a rigid solid frame and a special vibrator that leads it into an asynchronous motion.
As a frame material it is customary to use thick aluminum or high-quality alloy steel.
The main element of the vibration system is the engine, running from gasoline or electricity.
In order to activate it, it is necessary to start the engine, which will transmit a certain rotational motion to the vibrating system, and that in turn will set the necessary movement directly to the frame.
Thus, the frame of the working screed raises the concrete solution to move, removing from it all air voids and carefully ramming. The length of the rake itself can range from several tens of centimeters to ten meters.
Floating screed, which is equipped with a gasoline engine, has more power compared to electric.
In most cases, floating screeds with a gasoline drive are used to work in open spaces, as the engine emits harmful impurities into the atmosphere.
If necessary, work with concrete in confined spaces use a floating screed, driven by an electric motor.
It should be noted that with the help of the vibrating screen it is possible not only to ram the solution and remove the air spaces from it.
This floating device is also actively used when necessary to level the surface of almost any area.

This universal equipment can be bought in any specialized store, however its cost is quite high.
The best option is to assemble it yourself, the more so everyone can do it.
Preparatory stage
Floating screed in the technical plan is not difficult, but to build it yourself will require minimal knowledge in the field of construction.
As mentioned above, it is much easier to buy this device at a nearby specialized store, but if you want to save money and collect it yourself, you should prepare yourself thoroughly for work.
For its self-assembly it is necessary to have initial skills in welding and electricity. It is extremely important - when the floating vibrating shaker will be assembled by one's own hands, observe the safety rules.
Scheme of the screed device: 1- working plate;2- vibrator;3-shaft;4-shock absorbers;5- frame;6 - the engine;7- belt drive;8,9-pulleys;10- the drive shaft.
This is due to the fact that most of the work will be done using a three-phase trigger mechanism.
Experts consider the optimal size of the working part of the screed, three meters, and the engine's power is better to take no more than one and a half kW.
As practice shows, a floating screed with such parameters will allow to work with a solution, the thickness of which is up to twenty centimeters.
To manufacture this universal device with your own hands, you need to have a channel and armature at hand, as well as corners of steel or aluminum.
In addition, you need to stock up the bolts with different diameters, insulating rubber, quality three-phase cable.
You will definitely need an electric motor of suitable power, suitable starters for it, as well as the vibrating unit itself.
From the tool you should find a welding machine, a drill with a screwdriver, and a set of wrenches.
All materials must be qualitative and reliable, as during their operation the floating screed will be subject to rather high loads.
In addition, when assembling this device, it is necessary to observe the safety rules and ensure the reliable protection of all electrical components of the equipment.
It is advisable to make a detailed drawing of the assembled device in the preliminary stage of the work and perform all work in exact accordance with it.
Assembling the
To make a self-floating floating screeder able to successfully perform all its functions and has a high durability, all work on its assembly should be carried out correctly.
The work should begin with the manufacture of handles, for which you can use the reinforcement. Handles should be given a curved shape and attached by welding to the profile.

For more reliable mounting, we recommend using self-tapping screws in addition to welding.
To protect a person while working with the vibration control, the handles are carefully insulated with rubber material. Next, the basis of the device should be laid on an even surface of the workbench or table.
Afterwards, you can start installing the electric motor on the device.
To ensure that the vibration is distributed as evenly as possible, the motor is installed in the center of the profile.
Mount it best with two corners of metal. You can initially attach the corners to the engine itself, and then to the frame, and you can do the opposite.
The mounting of the vibration unit should be carried out in such a way that the cable coming from it is as firmly fixed as it is on the handles and on the profile itself.
The starter for the electric motor is best mounted on one of the handles, however, it is also possible on the engine itself. For the convenience of using the screed, its design can be made folding.
For this, it is necessary to cut the profile into two equal parts and make a bolted connection.
For leveling thick and compacted mortar layers, the device must have either a double or a frame structure. In this case, the manufacturing process will be exactly the same as in the first case.
The difference is that the engine will have to be mounted on a special mount in the very center of the entire construction of the screed.
The manufacture of a gasoline engine vibration meter is much easier, since there is no need to attach an electrical cable to the core.
Recommendations and tips
Many experts recommend making the mounting of the screed frame in three separate places.
It's better if the floating screed is completely collapsible, and for this, the skeleton should be made of four independent parts.

The screed should be used only for its intended purpose, and do not overload the installed engine. This will increase the life of the device.
The tamping process should be carried out evenly and neatly.
Do not pour a large amount of concrete, as in this case there will be problems with its ramming, and the screed will be overloaded. Also, do not let the device idle.
In the event that the solution falls below the level of the rake itself, it should be added with a shovel.
To assemble the screed for yourself at home with the right approach to the business everyone can.
Of course, it's much easier to buy this universal device, but in this case you have to spend quite a lot of money.
Do not forget that in many respects the longevity of the device depends on the observance of the rules for its operation.
