Types of screeds
As for the electric ones, they have a very high power. But due to the fact that it emits into the atmosphere quite harmful substances and elements, it can be used exclusively in the open air. But the second variation is simply indispensable in the field of construction work, and, moreover, in the interior area of the room.
over, they are used to carry out the process of smoothing a variety of area. By the way, to buy a device of such a variation is possible in absolutely any store of building direction.
Here are some negative points. The cost characteristics, not cheap at all. Also, there is no guarantee that it will serve you for a very long time. That is why, based on all this, one very significant conclusion can be drawn. Rather cheaper and more practical will be to construct a vibrating rail with your own hands.
So, what is the essence of making vibrating screed in order to make concrete on their own and without resorting to the help of specialists? This material is used not only in order to carry out the process of tamping the mortar, but also to kick out of the very thickness of the bubbles themselves, which in turn has a very bad effect on the qualities of matter, such as durability and, of course, durability.
Varieties of vibrating bars for laying concrete mixture
When constructing concrete pavement sites, roads, floor screeds, slab foundations, special attention is paid to the strength, evenness and smoothness of the surface. The method of leveling with hand tools is labor-intensive and time-consuming. Vibrating screeds for laying concrete, mortar and mixtures will help to improve the quality and speed up the work.
The vibration causes the freshly paved material to be compacted, removing air bubbles. After the concrete hardens, there are no cavities in it, which over time could get into the moisture and destroy the surface of the monolith. Screed processing improves the quality of the surface layer, increases: strength, water resistance, frost resistance and wear resistance.

Vibrating screed for concrete paving: how to make it with your own hands
Pouring a concrete screed in the house is quite a labor-intensive process. Not only that it is necessary to prepare the mortar, it is required to accurately level it on the screeds. Most often for these purposes the usual rule is used. And today we will talk about how it and some other parts and tools can be used to make a vibrating screed, with which it will be much easier to level the concrete. And the author of the YouTube channel Sharp Hammer knows how to do it.
The final word
Such a tool is extremely convenient in operation. At the same time it compares favorably with the one that can be purchased in the store. After all, it is much cheaper. At the same time, a homemade vibrating rail can be dismantled and parts from it can be used as an independent tool. Such an approach will unload the pantry of the home handyman, freeing him from the need to store disposable items that are sorry to throw away.

Scope and advantages of vibrating saws
High efficiency of this tool with a relatively small investment of energy resources and labor costs make it indispensable for the construction:
By the way! Elements made with the use of a hand vibrator, have higher strength and durability than those erected without a specialized tool.
Working with a vibrating rail has a number of features that distinguish it from other types of vibrating equipment:
- Exceptional ease of operation and maintenance. does not require long-term training and learning the technology.
- Compactness and therefore not difficult to transport, which facilitates relocation from site to site.
- Good performance with dry solutions (mixtures containing no more than 20% water).
- High performance for uniformly compacting concrete pavement with a thickness of 10-30 cm.
- The best levelling results (no defects on the surface of structures).
How to make handles?
Schematic diagram of the vibrating saw for making with their own hands
The frame for the motor is ready, the motor is rigidly fixed to it. We may consider that the lath for concrete compaction is ready to use. But it will not be very convenient to work with it yet: you need the control handles. First you need at a distance of 15 cm from the engine to weld (or screw) two square pieces of steel in a vertical position.
The size of squares should relate to the width of a channel. Drill a hole in the bottom corner of the square, and then from the hole, as from the center of the circle, draw an arc on the back side of the square. On this arc, holes should also be made at equal distances from each other. Handles for controlling the rail are fixed at the bottom.
The handles are fastened along the arc, depending on the user of the rail. Do not forget to put compressed rubber pads between the metal squares and the fasteners when attaching. They will eliminate the vibration from the rail to the control handles. When working on a large area is very important: vibration can cause ill health of the operator or even his mental disorder.
Anyone who wants to make a vibrating screed with his own hands, should clearly understand how it functions and what you need to make it. First of all, you should take into account that in most cases such a tool can not work independently. it needs a network ≈220 V or ≈380 V. You have thought about batteries? Yes, the idea is worthwhile, but even the most powerful ones (only light models are taken into account) can supply power to the engine for no more than 4-6 hours of continuous work, and their power is too low. Also on the market of construction tools are vibrating slats with a carburetor engine. This, of course, solves the problem of remote construction, but not completely.
Vibrator for concrete with your own hands
The essence of the purpose of this type of construction equipment is to remove the voids created by water and air from the concrete mixture, and this is possible due to the compaction of the adhesive agent and fillers. cement, sand and crushed stone. The process is under the influence of the medium-frequency vibration of the metal strip, set by the engine and transmitted to the work surface. All units of this type consist of three main parts: a long rail for smoothing, a vibration-creating motor, and a double or single control handle. The technical parameters of each unit can vary, depending on the need. For example, the length of the bar, varies from one to five meters, the motor can have different power, and the handle can be extended with special inserts to work at a distance.
In addition, there is a number of pluses, and most importantly, it is the speed of concreting of various sites, which increases by 5-7 times, depending on the coverage of the treated surface (rule length). In addition, at one time you can fill a large area with concrete, for example, pour the site full mixer (truck mixer) and do screed, moving the liquid concrete in boots. Such can not afford to hand screed, as this process is performed sitting or kneeling. Screed allows you to work with a layer of mortar up to 20 cm in thickness, which is not possible for manual screed, as the finisher is purely physically unable to properly compact such a layer.
Despite the fact that such a machine is automated carburetor or electric motor, it is still manual, because it is moved by the operator with muscular force, and people tend to get tired. On this basis, manufacturers produce rails from lightweight aluminum, but not from steel, which is much stronger, but heavier. This principle also applies to the control handles and engine mounts. Low weight is extremely important in road construction, where the vibrating rail is needed all the time and the operator has to work almost nonstop.
Electric drive or carburetor
Certainly, an electric vibrating rail is better in two ways, firstly, electricity is much cheaper than gasoline, and, secondly, the first option provides absolutely no emissions from fuel combustion. On the other hand, the need to connect to a stationary power source by default implies a power cord, which is a limiter for the ability to move away from the outlet. Of course, you can use an extension cord, but it can solve the problem only within the confines of the household plot, but not on the street.
For work in enclosed spaces, construction equipment that runs on gasoline is not suitable, because gassing at this level is life-threatening. Therefore, if we talk about vibrating screeds, you can not do without the electric motor, and we’ll briefly consider one of them, it’s PB-02 floating type. But to be honest, I don’t quite understand why it is considered floating, because this construction tool has nothing to do with water bodies, and its handle is rigidly held by a rule with a motor. Perhaps this adjective is used because the tool easily changes direction, like a swimmer on water.
The manufacturers claim that this unit is used without guides, but I think it’s just a marketing ploy, because the rail does not have such parts, so we are talking about beacons on the screed. Except that the screed is leveled only by them and not in any other way. Otherwise, the parameters are quite decent, for example, the aluminum profile varies in 1500, 2000, and 2500 mm, the power is 190 W, which is enough to process a layer of thickness up to 100 mm. Such a unit weighs 16,18 and 20 kg, depending on the length of the rail. As you can see, such a tool can work in private homes, high-rise construction, and even fill the entrances for trucks, given the fact that the vibration depth is up to 100 mm.
The top photo shows the petrol-powered Baumax BMX 5FH screed. Before talking about its technical characteristics, we should mention the main advantage of such a tool. it is mobile, and it is easy to transport. That is, with such a unit, you can go to any place where there is no stationary source of power or in the network are constant power outages. And when you work, you won’t have a power cord dragging behind you, which is a nuisance. The two main disadvantages of gasoline screed, is the high cost of fuel and the lack of ability to work indoors.
The length of the working profile of such a tool varies from one to five meters, which allows using a screed, as in road construction, so and to create park (garden) paths. The compacting depth of concrete mix is up to 150 mm, and this means that the tool is cost-effective for any civil works. The machine is equipped with a Honda GX-35 carburetor engine (the brand speaks for itself), rated at 1.6 horsepower, the equivalent of 1.2 kW. If you do not take into account the fact that the work will have to wear headphones, the real builders will enjoy this process.
Overview of top vibration laths for concrete paving
In terms of technology, the device is constructed of high quality aluminum or steel. The metal frame is the basis of the vibrating screed, but also one of the main elements of the device is considered a vibrating mechanism, due to which the screed performs vibratory compaction of concrete. The heart of the device is the engine, it can be electric or gasoline.
Gasoline and electric vibrating screed works under the following scheme: when you turn on the engine begins to work the vibration mechanism, then in the operating position the frame itself is brought from aluminum or metal, at the end of the vibration applies to a certain section of concrete. Screeds for concrete come in different lengths: from 0.5 m to 10 m.
Gasoline motor has the advantage of higher power, but the disadvantage is that it is difficult to operate the equipment indoors because of the exhaust fumes. Electric motor is ideal for working inside an apartment or house. Vibrating rail is designed not only to extract oxygen from concrete and compact it, but the device is also able to perform surface leveling.
The device can be purchased in the store, but its price is quite expensive, it is easier and cheaper to make a gasoline or electric vibrating screed for concrete with their own hands.
Types of screeds
The concrete saw blade is divided into 3 types:
- Floating and non-sliding type. the device is excellent for domestic use. The length of the vibrating rail does not exceed 300 cm, of course, the size of the rail can be chosen according to your own preferences. The power of such devices does not go beyond 1.2 kW. From widespread domestic manufacturers the leading models are: TSS and Krasny Mayak.
- Telescopic and sliding type. this type of tool is quite universal, can cope with the work on different areas, performs tamping and laying of concrete mortar. The sliding models have a working length of 10 m and equipped with a double frame for leveling the concrete surface. Professional equipment is produced by companies like Masalta and Euroscreed.
- Sectional type screed. the principle is to add a nozzle, if necessary in the work. Sections resemble frames in a triangular shape, which are fixed with bolts. This model has an easy regulation system and high functionality. They are more expensive than floating type slats. The tool is designed specifically for use in industrial settings. Sectional vibrating rail is made of chamber aluminum parts or metal channel, the connection is made in pairs.
