We choose a vibrolath for concrete laying

Concrete is among the most common materials used in construction. After pouring the working solution, air remains in it, which after hardening leads to a decrease in the strength of the monolith due to the remaining sinks, therefore the working mixture must be compacted. Also in some cases, the important point is that the final layer has a flat surface. In domestic conditions, with small amounts of work, different manual devices are used to achieve the result, but professionals use a vibrating rail for laying concrete. With it, the workflow is fast and efficient.

Purpose of the vibrolath

The vibrolath belongs to a number of the specialized, narrowly focused construction equipment. With it, perform the following types of work:

• stack working solution;
• tamped concrete;
• when concreting leveling the surface of the filled area, for example, when screed floors.

Also, the vibrolath is needed for semi-dry screed, which is gaining increasing popularity among builders lately due to the presence of a number of positive aspects in technology.

Vibroequipment of this type is necessary only for professional builders. When it is necessary to perform one-time work, it is not economically feasible to acquire such a construction tool.

Device and principle of operation of the device

Structurally, the vibrolath for concrete is simple equipment. The tool, regardless of the variety, consists of such main nodes:

• vibration, which includes the drive;
• slats (rules, frames);
• control systems.

In more detail the design of the unit is presented in the photo below.

As a drive, an electric motor or an internal combustion engine that runs on gasoline can be installed. The rail is made of steel or aluminum.Moreover, its length varies in different models from 0.5 to 10 m. According to the frame design, they are made in the form of one rule or 2 paired ones. The latter option is more convenient in operation, because it reduces the number of passes by vibration equipment on a concrete solution from two to one.

The principle of the instrument It consists in transmitting the vibration action from the vibrator through the frame to the concrete solution. This causes the poured mixture to be tamped down due to the more compact packing of the filler (for example, sand, crushed stone) and the extrusion of air. The vibrator creates oscillations due to the rotational energy of the engine.

Classification vibrolath

Vibration slats are classified according to the following criteria:

• type of engine installed;
• by design.

By type of engine

On this basis, the equipment is divided into 2 types:

• petrol;
• electric

Petrol rail different autonomy (does not depend on the network) and greater performance when compared with the electrical analog. It is used on open-site sites due to the fact that during operation, exhaust gases are generated.

Electrical engineering due to the absence of harmful emissions used in enclosed spaces. Also, electrical equipment during operation is less noisy. It is easier and more maneuverable than a petrol one.

By design

By design, the instrument is divided into the following varieties:

• equipment with a double frame (rigid);

• sectional units;

• telescopic double models - they have a sliding rail;

• floating units.

Vibrating installations with a rigid double frame have a fixed length. Moving along the guides, they are able to compact layers up to 0.3 m thick.

Sectional vibrating rail assembled from many individual structural elements. As a result, its length can reach 30 m. The increased dimensions provide high work performance, because a large area of ​​the treated area is captured in one pass. Higher weight allows you to increase the thickness of the compacted layer.

Sectional units are equipment for large-scale construction.

Telescopic model - It is a compact tool when folded. This feature is very convenient when it is necessary to transport the vibration equipment.The length of the frame of the sliding type is 2.5-4.5 m. Due to the relatively large weight, the vibrotool moves only along the guides.

Floating vibrolath is the finishing vibroequipment. Its other name is vibro-mop. It is used for compacting layers up to 200 mm thick and for their final alignment. Operate the unit without guides. Due to the fact that the rail is made of aluminum, it slides easier on the surface of the concrete solution. Also for this reason, the product has a relatively small mass.
On the market of construction tools, reversible models of various types are presented that can move in two directions: direct or reverse. To do this, the edges of the rails have a rounded shape. Rotation of vibration equipment for movement in the other direction occurs when the control handle is rotated.

Selection options vibrolyski

In order to efficiently perform work using a vibrating rod, it should be selected according to the following parameters.

1. Type of engine installed. If you have to perform work in relatively small indoor spaces, then only a power tool will do.Both petrol and electric models are suitable for outdoor use.
2. Drive poweron which the performance of the vibration equipment depends.
3. Frame length. For regular compaction and leveling large areas it is better to buy units with a long rail.
4. Material of which the rail is made. Aluminum frames are more expensive, but light, and steel - durable, are cheaper, but they are heavy.
5. Convenient control knob design (if available), which make in the form of a bicycle handlebars or sticks.
6. The speed of the equipment. Slow compaction with a higher frequency of vibrations produces a high-quality result.
7. Cost If the vibrotool is necessary for permanent use, then you should prefer the more expensive professional models, and for performing household infrequent building operations are quite cheap options.

Power is measured in kW at electric motors and in horsepower at the equipment working at fuel (gasoline). To buy an optimal model for the size of this parameter, it is necessary to determine the nature of the upcoming work, as well as their constant volume.

When the convenience of transportation is important, then telescopic models should be preferred.

Vibrolracks, despite the simple device, allow you to effectively tamp and level the concrete solution. Products are recommended for regular use. professional category from reputable manufacturers. Such equipment can be operated over a long period. It provides high performance and quality results. To occasionally ram up concrete in everyday life, fairly inexpensive models, even from little-known firms. You can also do homemade fixturewhich is enough for home construction.
