When pouring concrete it is important to achieve homogeneity of the composition, to exclude, if possible, the presence of air and water bubbles, uneven distribution of the aggregate. When creating reinforced concrete, there is another task: to ensure good adhesion of reinforcement with a solution. And they are all solved with a vibrator for concrete.

Since with stirring and laying the solution, the air is still falling, then it is necessary to delete it. Efficiently, the air comes out when vibration - it rushes up, while also a more uniform distribution of the filler occurs, the concrete becomes more dense and homogeneous increases its fluidity. Due to the removal of air bubbles and water pockets, its adhesion with reinforcement is improved. Such an uncomplicated process, and much improves the characteristics, giving products frost resistance.

Remove air and improve the connection between concrete particles - these are the tasks that the building vibrator performs

there is different types Concrete vibrators who distinguish with the type of installation:

• Internal or submersible building vibrators are used when creating massive structures. In private construction, they are used when filling the foundations and the construction of monolithic walls. Called so due to the fact that their tip is immersed in solution.
• Surface models are used when filling the screed, slabs of overlapping, large plates of concrete - concreting roads or platforms.
• Exterior vibrators are fixed outside on. It is convenient when creating high and narrow structures with a thick grid.

According to the type of engines used, the vibrators for concrete are electric, pneumatic, can work from the internal combustion engine.

Electrical in turn can operate from a two-phase network 42 V and from a single-phase 220 V. For private construction, electrical single-phase electrical applies more often. Moreover, the most common - deep. It is understandable, because the fill of the foundation is one of the most important and complex operations. And the deep vibrators for concrete are designed for these purposes.

Depth vibrators for concrete and prices for them

And then not everything is so simple. There are two types of devices of this type:

Manual deep vibrators consist of a durable hermetic case, in which the electromotor is concluded relative to low power - to 1kW. This asynchronous type engine, debaissions are connected to it, which create oscillations. The working part - the tip or creel is connected to the housing of the rubberized sleeve, through which the cable passes. The oscillations created by the engine are transmitted to the tip.

The mass of such a device is 6-10 kg. It is possible to work with not very large volumes: they have not very large power and, accordingly, a small radius of action.

The second type of depth vibrators consists of a motor, a flexible shaft and a working vibronic infant. In contrast to the previous version, the motor stands still, and the oscillations are transmitted through a flexible shaft. In this case, an important parameter is the length of the shaft, as it limits the freedom of movements, as well as the depth of immersion of Bulava. To seal concrete in the foundations of small structures, a shaft length of 4 m is sufficient, and it is better to take 6-10 meter for more overall.

How to choose

Important characteristics of deep vibrators for concrete are:

• The seal diameter is the zone in which oscillations are distributed. What it is more, the faster the seal occurs and fewer movements is required to achieve the result.
• Frequency and amplitude of oscillations. The more these indicators, the more active and faster the air is turned out. But the frequency of oscillations is selected depending on the type of concrete:
  • for fine-grained concrete compositions, high-frequency vibrators are used from 10,000 to 20,000 count / min;
  • for medium-trimmed - mid-frequency - from 3500 to 9000 count / min;
  • for coarse concrete, low-frequency models are required with frequency of oscillations up to 3500 count / min.
• The parameters of the working part are Bulava. They are chosen so that when immersing the distance from Bulava to the reinforcement frame cells was at least 1/3 of the diameter.

Since it is mostly fine-grained concretes for filling foundations, the frequency of oscillations should be higher than 10,000 count / min.

In the case of concrete vibrators, the price is a quality indicator. There is, in fact, in the characteristics such an indicator as a working time before failure. It is indicated in the clock. This parameter shows how many hours can work equipment to the first breakdown. And the higher the price, the more this resource.

How to use

Incorrect use of vibration not only does not bring benefit, but may harm: excessive duration of exposure will cause a bundle of a solution, which will negatively affect its fortress.

The exposure time depends on the plasticity of the solution and its fluidity. On average, the processing duration in one place is 30-60 seconds. As soon as the sediment stops and cement milk appears on the surface, the mace must be pulled out.

The step of rearrangement of the vibronic infantry or bulva depends on the radius of the action (seal diameter). It is 1-1.5 of its size.

When compacting the foundations or other structures in the formwork, you need to ensure that the tip does not tove over the wall of the formwork. The minimum distance to the shields should be about 10 cm.

How to prepare a deep vibrator for concrete to work in the video. And one more important nuance: to start vibrations, it is necessary to knock on a slightly onto the bullet. Then the oscillations will begin.

Surface (platform) models

This type is less common, but it can be used in private house-building, and in particular for building a bath. With the erection of small structures, the foundations are rarely very deep, often have a medium or finely muffled, so that the use of surface concrete vibrators also sufficiently compact the solution. In addition, it can then be used when pouring a.

The parameters of the selection are the same - amplitude and frequency of oscillation, the number of hours to failure, the radius of action. The vibrator motor itself is installed on the platform, tightened by bolts.

When working it is important to pull up the bolts in the places of fastening the working platform. It will provide better transmission of oscillations, and will not allow the motor to roll off from the mount. It is necessary to do it regularly - at least twice a quarter of an hour.

Before working, the installation must be ground, then turn on and slowly move along the plane. To achieve a good effect, the processing band should be overlapped by about 10-20 cm.

How to make a vibrator for concrete with your own hands

The construction vibrator can be made on the basis of any power tool with an adjustable number of revolutions. Its power should not be too large - a special load on the spinning part cannot be foreseen. The whole task is to convert the torque of the motor in the tip of the tip. This is done using debaission placed inside the hollow tube.

Punching perforator

The simplest homemade vibrator for sealing concrete can be made from the perforator. It should work in impact mode. Actually, a typical peak can be immersed in solution, but after use as a vibrator it will be necessary, most likely to replace. Concrete - an aggressive environment and rust metal will begin quickly.

To increase productivity to the peak, you can do a few transverse rods. This will increase the radius of coverage, but can create difficulties in the presence of fittings. More efficiently and safely screwed at the end of the peak of the puck. The exposure area also increases, but no problems with reinforcement.

Another interesting way to use a perforator for sealing small amounts of concrete You will see on video.

From a drill or other similar tool

Make a manual submersible vibrator with your own hands in several ways. One of them is simple and does not require special skills, the second is more complicated.

Fashion first

Buy the finished mace with the shaft, but without a drive. They are sold in the same stores where vibrators. To process a layer of a solution of a small depth - to 1 meter - the shaft will cost about 1.5-2 thousand rubles, more than 2-2.5 thousand rubles. All you will have to come up with how to attach this hose to the existing drive.

Someone attracts the tip to the drill, someone to the Bulgarian. The main task is to attach the inner tip to the tool axis. The inner shaft of Bulava has the shape of a hexagon. If in the tool the same way out, and even the coincidence in size, then there are no problems. But if the form is different, you need to make an adapter.

Then it will be necessary to secure another protective shell. It ends with a metal ring with internal thread. It is easier not to make an adapter with the same thread, but to drill three or four through holes of a small diameter in the circle ring. They screw the bolts of a suitable diameter. Cutting bolts, fasten the shell on the tool. After that, you can check the tool in operation. Do not forget that in order for the vibrations started, the tip should be on something to hit.

Method of the second

Make a vibronic conference for a concrete vibrator with your own hands. Below is the photo on which the Maulava are depicted of different types. The principle of action is one - it is necessary to make a device that will shift the center of gravity, which is why oscillations are obtained.

One of the types of tips for the construction vibrator is presented in the next photo. It consists of a metal case, in which bearings are fixed at the top and bottom. Metal rod inserted inside the bearing. On the part that is inside the case, on one side there is a load for shifting the center of gravity. In this check, one of the important tasks is to ensure tightness.

If the depth of the processed solution is small - about a meter, you can not do a flexible hose, but take a long metal pin. The lower part of it with the debaner cargo will be enclosed in the housing, and the gap between the drive and the mace must be protected by a hose high pressure with thick reinforced walls. There will again arise the problem of docking pin and protective shell with the existing drive. It can be solved as described above.

With this option of a self-made manual vibrator will work uncomfortable: the return from the Bulava will be tough. To soften it, make part of the immersion vibronic flexible vibronic. For a flexible part, it is possible to use a durable steel cable, which is welded on one side to the Metal pin of the Bulava, and on the other, they make an adapter that will be convenient to mount on the drive axis. The cable itself hides in the same piece of high pressure hose.

Regardless of which of the options are selected, the outer case is better made from the stainless pipe. Since concrete is an aggressive environment and the steel will destroy quickly. Although, on the sample, you can do from the usual steel.

The diameter of the pin is not less than 1.5 cm, and the cable to which the makeup and the axis of the instrument will be connected, should be resistant to twisting.

Surface vibrator for sealing screed with your own hands

To equalize the surface of the screed, use the beacons and the rule that the solution is smoothed. But at the same time inside the solution, air bubbles and inhomogeneities remain. Vibration is also needed to increase density and strength of the screed. But since the depth of the layer is small, then the submersible vibrators do not fit here. Use special models - superficial.

In order for small amounts of work is not to spend money on the purchase of a tool, you can make something similar from any engine, attaching to its axis an asymmetric cargo, which will cause oscillations when rotating. The motor is installed on a solid bar, can be made of wood. A handle must keep the plank for which the surface vibrator will move along the solution.

The result of processing is the same: increases fluidity with simultaneous increase in density. One of the options for homemade construction vibrator you will see in the video. It can be taken as a basis by using any unnecessary motor, not a drill (the tool is still a pity).

Hello! I would like to touch on this revocation very intimate and delicate theme ... "Vibrators with remote control", or, as they are also called, "vibrators for lovers". What is it? Let's figure it out).

Firstly, there are several varieties of them, at least these "devices" may differ from each other by controlling.

The most new invention in this area, let's say, "smart" vibrator, which is not controlled by a remote control, but using your smartphone. A special application is loaded to your gadget, with which, in fact, you are controlling this intimate toy. Manufacturers argue that in this way, your partner will be able to control the vibrator even from you in thousands and thousands of kilometers. Naturally, it will significantly revive and diversify your sex life. Bring something new, give sharpness.

Next, so to speak "ordinary" vibrators. With control panel. There are also a great set: and vibration, and vibrators for double stimulation, and anal and vaginal. The control panel can also be both ordinary and with vibration function (this is done in order to make your partner, holding the remote in the hands, felt the same as you during this process). There is also a huge variety of materials from which these toys are manufactured. Naturally, all the above listed factors in the aggregate affect the price, which can be acceptable (if the vibrator is simpler), and the transcendental (well, you understand if you choose to the toy with all sorts of "frills"). It is usually very easy to care for these vibrating massagers. The device is charging from the usual outlet in two hundred twenty (220) volts. The console is on ordinary finger batteries (usually from two to four pieces). However, regardless of what form, color, material and management type, you will choose when buying a vibrator, all the same they have one function - stimulation of the "GI" point ("G") and the clitoris. Of course, there are even additional features that again depend on the form and assign the device you choose, but specifically these functions are the main.

I think I have already revealed this topic. As they say, you need not to talk about love, but to do it). All successful purchases, good, and passionate relationships!). Buy such pleasant little things, and please your soul mate with new sensations.

Before applying, be sure to consult a specialist

Video Overview

Vibrator with remote control

The most important technological element in obtaining a solid monolithic concrete block after pouring the solution to the formwork is its seal by extrusion and displacement of the remaining air. Previously, it was traaming of a flooded concrete or "pinching" - pinches with sharp pins. In modern technology of monolithic construction applies more effective method - Vibration, under the action of which remaining inside the air itself comes up. To create a vibratory load, a special device is used - a vibrator for concrete.

Types of vibrators for concrete

In monolithic construction for concrete seal apply different types Vibrators. In the appointment, the following types are distinguished:

• superficial press vibrators designed to seal concrete when pouring floors, overlaps of a small thickness;
• external vibrators used to create vibrations when filling out of the hustically marked reinforced concrete thin-walled structures through the elements of the outer formwork;
• internal or submersible vibrators used in the fill of massive and volumetric structures: foundations, woodworks, supports, dams, etc.

According to the method of creating vibrations and an energy source, tools are divided into the following types:

The frequency of the created vibrations of the actuator is distinguished:

• low-frequency vibrators with frequency of oscillations up to 3.5 thousand count for sealing concrete mixtures consisting of coarse aggregates;
• high-frequency vibrators with a frequency of 10 to 20 thousand. CAL / MIN to work with fine-grained concrete solutions;
• mid-frequency vibrators with a frequency of 3.5 to 9 thousand count / min for concrete with a medium-sided structure.

Principle of the internal vibrator for concrete

The most common submersible vibrators of an electromechanical type have an electric motor in their composition, a flexible hose (drive mechanism) and a working tip (Bulaw or bayonet) emitting vibration. A powerful electric motor (1 kW and more) has one or three-phase power from the AC network. With the help of a flexible shaft, the length of which can be from 1 to 7m, the rotation of the rotor is transmitted to the vibration tip.

The vibration aid is a stainless steel tube for corrosion resistance from the action of an aggressive concrete solution. In order to protect against moisture, the ends of the driving hose are sealed with rubber gaskets, and the nozzle has a polymer shell. Inside the nozzle rotates on the bearing massive eccentric steel shaft. The mismatch of the center of gravity of the shaft relative to the axis of rotation leads to the appearance of vibration oscillations of the nozzle, the frequency of which depends on the speed of rotation of the rotor of the electric motor.

The form of the working part of the vibrationscape may be cylindrical (male) or conical (bayonet). The first is designed to compact concrete in forms and formworks with a normal reinforcement frequency. The second type of nozzle is used with a thick reinforcement grid of filament forms. In a set of the vibrator, there may be several vibrations, bulbs of different diameters. The weight of the engine, the length of the flexible drive should be such that one person can cope with the tool. If the length of the shaft is more than one and a half meters, then work with the device must be performed.

How to make the vibrator for concrete

A vibrator suitable for home construction can be made by the most powerful electric drill or perforator. A steel cable should be used as a flexible drive. To collect a vibro-pool, the following details will be needed:

• cut of stainless steel tube 50 cm long, an outer diameter of 55 mm, the thickness of the wall is 1.5 mm;
• roller bearings with an external diameter of 52 mm, for example, grade 12304 or NF304 with dimensions of 52x20x15 mm - 2pcs;
• metal circle of 55 cm long, with a diameter of 20 mm;
• metal square rod 40 cm long and 2.5 cm sides;
• iron cover with an inner diameter of 55 mm for the tube terminal cap;
• steel cable with a diameter of 15 mm and up to 1 m long with brewed ends;
• sleeve from PVC tube internal diameter 55 mm and length equal to the length of the cable.

To get a working shaft - eccentric, you need to weld to a metal round rod along the entire length of the square rod, retreating from one end of at least 15mm as a landing place for the bearing. Next, the assembly of the unit should be assembled in the following order:

1. put the working shaft in the stainless tube and from both ends to score bearings filled with lubricant. They should be tight without distortion and completely inside the tube. As a result, the shaft must turn freely from hand, not to act beyond the housing from the working end;
2. the working end of the tube is drowning in the lid, putting it on epoxy glue or sealant;
3. on the free end of the shaft in the center, drill a hole with a depth and diameter of 15 mm. To strengthen the cable in this hole, you need to drill another hole perpendicular to the axis of the shaft at a distance of 7 mm from its end with a diameter of 4 mm and chop the thread under the clamping screw there. Strengthen one end of the rope on the shaft using a clamping screw;
4. wood on the cable and open end of the PVC hose tube (sleeve). It must be put on tight and tightly and with some reserve in 5-6cm overlap the connection site. Strengthen the connection of the sleeve with the tube can be using a consuming clamp;
5. the other end of the cable to strengthen the drill in the cartridge. After that, the tool is ready for work. To protect the vibrator body from a chemically aggressive cement solution, the action of which under the action of vibration is only enhanced, you can wear a rubber or plastic case on it.

Video: Vibrator depth for concrete with his own hands

For effective action The vibrator should follow the following requirements for its use:

1. immerse the mace into concrete smoothly with a slight inclination to maximum depth;
2. to keep submersible in one place for 20-30 seconds (depends on the plasticity and composition of concrete), while the surface of the dive location does not cover cement milk;
3. to remove the mailing to the bead smoothly and immersed in a neighboring place at a distance of 1-1.5 radius of action (depends on the power of the device, it is determined visually by the resulting liquid circle around the treated point);
4. you can not abuse the vibrator and abate it for too long, as the bundle of concrete fractions can begin, which worsens the quality and;
5. with the monolithic erection of high walls, layer-by-layered concrete is recommended every 1.5 meters of fill thickness.

In compliance with these measures, the vibrator significantly reduces the laboriousness of the work and provides high quality and strength of the fill.

When filling the foundations, columns and other reinforced concrete structures in the concrete mass appear emptiness, the presence of which negatively affects the quality of the monolith obtained. With the advent of special vibrators for concrete in the market for concrete, the solution of this issue has become another simple technological stage - the vibration removal of the concrete mix. In this article we compare the 10 best vibrators for concrete in the price category from 4 to 78 thousand rubles.

Drop and surface - what is the difference?

Already from the name it is obvious that the main task of these devices is to transmit the vibration of concrete mass in order to align its density throughout the working volume of the formwork. Before talking about the device and principle of work, it is worth mentioning two types of vibrators for concrete: deep (submersible) and superficial (external, platform). Despite the same persecuted goals, they are constructed and they work a little differently.

Deep vibrators are immersed in concrete mix . They consist of a drive, a flexible shaft, protected by power armor, and the vibronic opponent (Bulava). With the drive, a torque is created transmitted by the tip through a flexible shaft. The tip is a hermetic design of the oblong shape, inside which is the core and the slider. The movement of the core runner and ensures the creation of high frequency vibration.

External vibrators are not in contact with concrete, but affect the mixture through the formwork elements to which they are mounted. The design of such aggregates also suggests the presence of a drive, in which the so-called decalances are mounted on the rotor. The asymmetric efforts created by their rotation lead to the appearance of vibration transmitting the base on which the surface vibrator is installed. As a rule, it is resorted to its use only in cases where submersible devices are not suitable due to the high density of fittings or small size of the structural structure.

Varieties of vibrators for concrete and the criteria for their choice

To begin with, we consider general characteristicswho are relevant when choosing both deep and platform devices.

Now let's try to deal with the features of the selection of deep-type devices. They are the most popular solution for filling reinforced concrete structures.

* Consider that when working the tip is greatly heated - this is a normal phenomenon, just be careful.

Well, if you decide to purchase a superficial vibration, then when you choose, you need to take into account the following features that are most of the part relate to the snap.

It is worth noting that the effective radius of action and those and other equipment options usually does not exceed 0.5 m values. This suggests that the step of rearrangement of the depth vibrators should not exceed this value.

Accessories and spare parts

For the most part, this issue concerns the submersible type equipment, in which flexible shafts and tips are consumables. Most often, the manufacturer offers a set of shaft and makeup for complete compatibility of components. The cost of such products depends on their parameters, for example, the diameter of the tip and the length of the flexible shaft.

Options for self-made vibrators for concrete

If there are some components, as well as the skills of working with tools, you can make a homemade vibrator. Here you will not find superficial drawings - with the help of simple schemes, we will simply obscure you on thoughts regarding the future design.

Important! As practice shows, in the absence of everything or most of the device being necessary for the manufacture of the device, it is better to abandon the homemade in favor of the factory product. It is faster, more reliable, safer.

From lawn mower

The drive of the future vibrator can serve as a motor from an electric lawn mower. Those. The question is initially resolved with a third part of the equipment. It remains only to figure out the flexible shaft and the mace. The figure below something like the drawing diagram of the submersible product.

The vibronic infantry can be made of two trimming pipes of a suitable diameter. For these purposes, one end of the pipe is closed with a plug or brew. Install the bearing in size and eccentric, the parameters of which will affect the amplitude of oscillations.

Eccentric can be chopped on the machine or make from a regular shaft, welding to it from one side of the rod. I need at least two bearing to ensure normal boulas. The second bearing lock the eccentric, the tip of the shaft of which can have a different geometry to connect through the head to the tip of the trimmer head of the lawn mower. The last connection is carried out through the bolt and head on its size. The connection site is hidden the second part of the pipe from the tip. Spit cable protect with a solid hose that attach to a mower and tip using clamps. On the video below, such an instance is shown in the finished form.

Checked - works!

From an unnecessary electric motor

You definitely have than replacing the factory vibrator, if there is an unnecessary electric drive. For example, from the pump, washing machine, etc. 3000 revolutions per minute will be enough for these purposes. Below is a scheme of the self-made product.

The whole secret is to reliably attach towing cable, which will transmit the torque to the eccentric in the vibronic infant. To do this, it is necessary to drill two holes in the protruding part of the actuator shaft: in one insert the cable, to another - bolt, with which this cable will be fixed. Now this part needs to be protected from dirt and moisture to avoid damage and drive. A peculiar casing makes a suitable diameter from a pipe by making several longitudinal cuts from one of its sides and giving the form of the cone. The slots will later need to brew. The casing is put on a durable thick-walled hose, inside which the rotating cable will be. The fixation of the hose is carried out using a clamp compound.

Make eccentric and secure it with a cable on the same principle by which the cable has connected with the drive shaft. As a vibronic hull, use the pipe of the desired diameter with one sealed end. Inside the pipe, place two bearing and eccentric, from the other end, breed a protective cover.

You can adapt to the seal of the concrete mixture, you can both a conventional drill that will serve as such a necessary drive. From the power of the drill will depend on how long the flexible shaft can be made. The diagram of such a device is shown in the figure below.

To transmit torque in homemade vibrators for concrete, a towing cable is traditionally used. If the shaft length does not matter, then you can use the steel rod, at the end of which debaissions are welded. Secure the cable on the drill with the cartridge. Use the rigid hose of the appropriate diameter, inside which this cable will rotate, securing it on a drill with a clamp. At the other end of the cable, attach eccentric. For these purposes, drill a pair of holes in it, in one of which place the cable, to another - bolt for fixing it.

Now it remains to make the vibronic chassis and our homemade depth vibrator will be ready. Case Make out of two parts: Take the pipe of the appropriate diameter, muffle it on the one hand, insert a pair of bearings and eccentric as the scheme above. The connection area of \u200b\u200bthe cable with an eccentric is protected by casing made of pipe cutting, as shown in the previous example. Cook the two parts of the Bulava and connect the tip with the shell of the flexible shaft.
