We make a vibrator for concrete with our own hands. Overview of manufacturers of internal vibrators

Initially, vibrators were used not at all to satisfy a sexual dream, but to treat women's diseases. Modern men and women perceive this device ambiguously. Because medicine considers human sexual health to be an inseparable part of health in the aggregate, it is quite possible to consider a toy as an assistant in sex from this point of view.

Varieties of vibrators

Not all models outwardly resemble a penis, but typical ones have just such a shape. First of all, stimulants differ in the material from which they are made:

plastic is the most inexpensive material, extremely vaguely reminiscent of human flesh to the touch;
hygienic rubber is a more flexible material, not as rough as plastic, but with an unpleasant cool smell. The service life of a rubber device is short;
latex - more like human skin. Quite flexible and rapidly heats up to body temperature without cooling down;
gel and silicone are new generation materials that are virtually indistinguishable from skin to the touch. Upon contact, they save body temperature, but have one significant drawback - they need special care;
cyber silicone and cyber skin - the best imitation of the original to date.

In addition, vibrators differ in the speed of movement.

Through countless studies, it has been found that the optimum vibration rate is 80 cycles per minute. Stimulation with exactly this intensity allows women to achieve orgasm in case this did not work out during normal sexual intercourse with a partner. At this frequency, only expensive models from famous manufacturers are able to work.

There are models equipped with a device for stimulating the clitoris, that is, they are able to vibrate and rotate.

On sale, it is also possible to find thin models of small girth, equipped with a fuse from all kinds of force majeure situations associated with too deep penetration.

There are even small toys - “cigarettes”, which are prepared only for clitoral stimulation, and there are vibrating testicles that easily penetrate inside the vagina.

Most of the modern models of vibrators are able to work not only from the mains, but also from batteries, which provides ample opportunities for activity. The main thing is to buy strong batteries with a long service life in advance.

On the shelves of modern sex shops, you can also find double models, prepared for simultaneous stimulation of the vagina and anus.

Instructions for use

Even if the vibrator is bought extraordinarily for sexual games with a partner, it is better to test its effect on yourself first. This will allow you to relax and concentrate on the sensations without being distracted by something else.

Experimenting with the lights off under the covers is better to postpone until later - until the moment when the toy is sufficiently studied and you will be able to use it even with your “eyes closed”.

At first, you need to allow the body to get used to the device.

It is not necessary to immediately turn on the vibrator and proceed to the main action. It is better to walk them over each body, paying special attention to erogenous zones. We are talking about the neck, face, nipples, abdomen, inner thighs, etc.

If the rubber itself from which it is made prevents the device from sliding, it is allowed to use a cream or a special lubricant, and it is allowed to drive it over clothes, say, silk underwear.

Turning on the device, increase the influence by pressing it to the most emotional places. It is worth trying to experiment with the force of pressure. The greater the power of the device and the stronger the woman presses it to herself, the less she will feel its vibrations.

By firmly holding the device in your hand, you can slightly reduce the vibration due to its absorption by the brush. As soon as a woman feels that she is ready to try the stimulant in action, she can introduce it inside.

Using a vibrator in sexual games with a partner, it is better to put a condom on him in advance, only if anal caresses are planned.

How to use a clitoris vibrator

Clitoral stimulators are represented by silicone or rubber plates of various shapes, which can either be worn on the finger or attached to the hips with the help of belts.

When choosing such a device, you need to be guided by your own preferences and ease of use. In addition, before use, it is recommended to read the instructions for the device, because this is necessary for the theoretical assimilation of all its functions, modes and buttons.

Subsequently, the operation of the device can be adjusted based on your own feelings. In the case of devices that are worn on the finger, the frequency of movement and the force of pressure will have to be adjusted manually.

How to use an anal vibrator

The main condition is the use of a sufficient amount of lubricant.

Lubricate the anus.

By massaging and caressing the anus with your finger, prepare it for the entry of the device.

Carefully, with rotational movements, push it as deep as possible.

If a woman is quite aroused, the stimulator can be entered in a more turned on state and begin to imitate the movements of the penis during intercourse.

Devices of this type can also bring great pleasure to men. By stimulating the prostate gland, located approximately 2–2.5 cm from the sphincter ring just behind the perineum, with a vibrator, it is possible for a man to get unimaginable pleasure and increase orgasm.

To do this, you need to enter the included device at all shallowly and make a movement with its tip towards the scrotum. Whether a woman does it positively or not, her partner's penis will "tell" her, the one that should respond to the glorious sensations in an appropriate way.

About vibrator damage

The toy provides ample opportunities in sex. It will exclusively suit experienced couples who have been living together for many years and are looking for ways to diversify their sex life.

Learn one thing. If a woman regularly gets an orgasm only with a vibrator, it will be difficult for her to refuse it. This connection can lead to a decrease in the performance of other methods of sexual stimulation.

There are no other contraindications to the use of the device.

The most important technological element in obtaining a durable monolithic concrete block after pouring the mortar into the formwork is its compaction by squeezing out and displacing the remaining air. Previously, this was done by ramming poured concrete or “bayoneting” - piercing with sharp pins. In modern technology of monolithic construction, a more efficient method is used - vibration, under the influence of which the air remaining inside rises on its own. To create a vibration load, a special device is used - a vibrator for concrete.

Types of vibrators for concrete

In monolithic construction, various types of vibrators are used to compact concrete. According to their purpose, the following types are distinguished:

surface press vibrators designed to compact concrete when pouring floors, ceilings of small thickness;
external vibrators used to create vibrations when pouring thickly reinforced reinforced concrete thin-walled structures through the elements of the external formwork;
internal or submersible vibrators used when pouring massive and volumetric structures: foundations, grillages, supports, dams, etc.

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

According to the frequency of the generated vibrations of the actuator, there are:

low-frequency vibrators with an oscillation frequency of up to 3.5 thousand counts/min for compacting concrete mixtures consisting of coarse-grained aggregates;
high-frequency vibrators with a frequency of 10 to 20 thousand counts / min for working with fine-grained concrete solutions;
medium-frequency vibrators with a frequency of 3.5 to 9 thousand counts / min for concrete with a medium fractional structure.

The principle of operation of the internal vibrator for concrete

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

The vibrating nozzle is a stainless steel tube to resist corrosion from aggressive concrete mortar. In order to protect against moisture, the ends of the drive hose are sealed with rubber gaskets, and the nozzle has a polymer shell. Inside the nozzle, a massive eccentric steel shaft rotates on a bearing. The discrepancy between the center of gravity of the shaft relative to the axis of rotation leads to the appearance of vibrational oscillations of the nozzle, the frequency of which depends on the speed of rotation of the rotor of the electric motor.

The shape of the working part of the vibronozzle can be cylindrical (mace) or conical (bayonet). The first is intended for compaction of concrete in forms and formworks with a normal frequency of reinforcement. The second type of nozzle is used with a dense reinforcing mesh of poured forms. The vibrator set may include several vibrating nozzles, clubs of different diameters. The weight of the motor, the length of the flexible drive must be such that one person can handle the tool. If the length of the shaft is more than one and a half meters, then two people must work with the device.

How to make your own vibrator for concrete

A vibrator suitable for home construction can be made on the basis of a powerful electric drill or hammer drill. A steel cable should be used as a flexible drive. To assemble the vibration nozzle, you will need the following parts:

a piece of stainless steel tube 50 cm long, with an outer diameter of 55 mm, and a wall thickness of 1.5 mm;
roller bearings with an outer diameter of 52 mm, for example, grades 12304 or NF304 with dimensions of 52x20x15 mm - 2 pcs;
metal circle 55 cm long, 20 mm in diameter;
metal square rod 40 cm long and 2.5 cm sides;
iron cap with an inner diameter of 55 mm for plugging the end side of the tube;
steel cable with a diameter of 15 mm and a length of up to 1 m with welded ends;
a sleeve made of PVC tube with an inner diameter of 55 mm and a length equal to the length of the cable.

To get a working shaft - an eccentric, you need to weld a square bar to a metal round rod along the entire length, stepping back from one end of at least 15 mm as a seat for the bearing. Next, assemble the unit in the following order:

insert the working shaft into a stainless tube and hammer bearings filled with grease from both ends. They should enter tightly without distortions and be completely inside the tube. As a result, the shaft should turn freely by hand, not protrude beyond the body from the working end;
plug the working end of the tube with a lid, putting it on epoxy glue or sealant;
at the free end of the shaft, drill a hole in the center 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 cut a thread for the clamping screw there. Fasten one end of the rope to the shaft with a clamping screw;
put a PVC hose (sleeve) on the cable and the open end of the tube. It should be worn tight and tight and with some margin of 5-6 cm overlap the junction. You can strengthen the connection of the sleeve with the tube using a clamp;
fasten the other end of the cable in the drill chuck. After that, the tool is ready to work. To protect the body of the vibrator from chemically aggressive cement mortar, the action of which only increases under the influence of vibration, you can put on a rubber or plastic cover on it.

For the effective operation of the vibrator, the following requirements for its use should be met:

immerse the mace into concrete smoothly with a slight slope to the maximum depth;
keep immersed in one place for 20-30 seconds (depending on the plasticity and composition of the concrete), until the surface of the immersion site is covered with cement laitance;
remove the mace smoothly without jerks and immerse it in a neighboring place at a distance of 1-1.5 of the radius of action (depends on the power of the apparatus, is determined visually by the formed liquid circle around the treated point);
it is impossible to abuse the vibrator and overexpose it for too long, as the stratification of concrete fractions may begin, which worsens the quality and;
in the case of monolithic construction of high walls, layer-by-layer strengthening of concrete is recommended every 1.5 meters of pouring thickness.

If these measures are observed, the vibrator significantly reduces the labor intensity of work and ensures high quality and strength of the casting.

The use of a deep vibrator will help build a strong and durable monolithic structure. We will talk about the intricacies and rules for choosing this device further.

Device and principle of operation of a deep vibrator

A deep vibrator for concrete is a device whose main function is to compact concrete, that is, to get rid of excess air in a space that is filled with concrete.

This process increases the adhesive force between the concrete mortar and the metal reinforcement, thus obtaining a complete and very strong monolithic structure.

The principle of operation of the device involves the destruction of the friction force inside the concrete mass. The voids removed from the concrete increase the adhesion of this material.

If you refuse to use a deep vibrator, then the concrete surface will turn out to be loose, unstable to vibration, load and temperature changes.

In the process of using a deep vibrator, the process of mechanical oscillation of the vibrator occurs, so the concrete mixture fills all the corners of the formwork.

The device starts working after the vibrator head is in the concrete mixture. The diameter of the vibrating head varies from 2.5 to 10 cm. The size of the diameter depends on the shape of the concrete, the size of the structure, the amount of reinforcement. Immersion of the vibrating head ensures uniform distribution of the concrete mixture along the perimeter of the filled area. When stitching several layers of concrete, the vibrator should be lowered into the previous layer, at least 12 cm. This action will lead to bonding of the layers.

Benefits of using an internal vibrator

reduction of working time with concrete,
increasing the strength and reliability of monolithic foundations,
acceleration of the construction process,
reduction in the amount of work done
ease of transportation,
the possibility of selecting and adjusting the diameter of the vibroneedle.

Varieties of deep vibrators

Depending on the place of work, vibrators for concrete are divided into devices:

deep or internal type, which work inside the concrete solution and carry out the transmission of vibration through the body device;
external type, which are fixed on the formwork with bolts, they transmit vibration through the formwork;
surface type - are installed in the upper part of the laid concrete mixture, carry out the transmission of vibration through the working surface.

In relation to the principle of work, there are:

1. Deep high-frequency vibrator is the most popular and demanded type of vibrator, due to the location of the engine in the vibrator head, the quality of compaction is improved. Requires additional use of an external converter.

2. Manual deep vibrator - used to create vibration in basement or column structures. They are easy to transport and use.

3. Mechanical or deep vibrators with a flexible shaft consist of:

electric motor - makes up the main part of the device, in rare cases it is allowed to use a gasoline or diesel engine, the engine performs the function of transporting the rotational force to a flexible shaft;

flexible shaft - which transmits rotational force to the vibrating needle;
vibroneedle or vibrotip - a device that directly performs rotational movements and vibration.

4. Pneumatic or portable deep vibrator is distinguished by its operability, which is carried out by supplying compressed air, they are distinguished by reliability, high wear resistance and long service life. Requires a compressor.

5. Electric vibrator works due to the presence of an engine: electric, gasoline or diesel.

1. Deep vibrator price depends on such factors:

the size and power of the device,
vibrator type,
type of drive,
number of vibration cycles,
additional functions,
manufacturer.

2. Pay attention to the technical characteristics of the device, compare them with the requirements and scope of work.

3. To buy a deep vibrator, contact a specialized store, where experienced consultants will provide certificates of conformity and help you choose the device according to individual preferences.

4. Pay attention to the number of vibration cycles, is an indicator of the performance of the internal vibrator. The optimal number of cycles for concrete bases is 5000.

5. During operation, do not touch the formwork with a vibrator to avoid damage to the casing. For these purposes, a protective cap is used.

6. Do not use the internal vibrator at a height that exceeds 1 km.

7. To ensure good performance when working with the internal vibrator, the air temperature should not be more or less than 18-22 degrees.

8. Ensure good ventilation when using this product.

9. To prevent air from entering the concrete mixture again, the internal vibrator should be gradually pulled out.

10. The length of the vibratory tube should be such that it can easily reach the base of the structure to be poured.

11. The pneumatic type internal vibrator features high performance, easy maintenance and maintainability.

12. Mechanical vibrators are affordable, but at the same time, the quality of concrete is much lower than when using pneumatic ones. They are used in facilities where there is no connection to electricity. The main disadvantage of a mechanical vibrator is the presence of a flexible hose, and the possibility of cement solidifying in it. If this happens, then after turning on the device, the hose will break.

13. The most high-quality vibrator is high-frequency, it is used in the construction of large monolithic structures. Such a device is easily transported, has a small motor, as well as built-in or separate converters. Most high frequency vibrators are equipped with a vibration strength adjustment function. The absence of a flexible shaft guarantees high reliability and durability of operation. But, these devices are very expensive, so not everyone is available.

Overview of manufacturers of internal vibrators

High-frequency type vibrators are characterized by high efficiency, long service life and maintenance-free operation. It is possible to use such devices at low air temperatures and in hard-to-reach places.

When pouring foundations, columns and other reinforced concrete structures, voids appear in the concrete mass, the presence of which negatively affects the quality of the resulting monolith. With the appearance on the market of special vibrators for concrete, the solution of this issue has turned into another simple technological stage - vibrocompaction of the concrete mix. In this article, we will compare the top 10 vibrators for concrete in the price range from 4 to 78 thousand rubles.

Deep and surface - what's the difference?

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

Deep vibrators are immersed in the concrete mixture. They consist of a drive, a flexible shaft protected by power armor, and a vibrating tip (mace). The drive creates a torque that is transmitted to the handpiece through a flexible shaft. The tip is a sealed oblong-shaped structure, inside of which there is a core and a slider. The movement of the slider along the core ensures the creation of high frequency vibration.

External vibrators do not come into contact with concrete, but act on the mixture through the formwork elements on which they are mounted. The design of such units also implies the presence of a drive, in which the so-called unbalances are mounted on the rotor. The asymmetric forces generated during their rotation lead to the appearance of vibration transmitted to the base on which the surface vibrator is installed. As a rule, its use is resorted to only in cases where submersible devices are not suitable due to the high density of reinforcement or the small size of the structure to be poured.

Varieties of vibrators for concrete and criteria for their selection

To begin with, consider the general characteristics that are relevant when choosing both deep and platform devices.

Common to all vibrators for concrete compaction

Parameter	Meaning	Note
type of drive	electric	The most popular solution, because with such devices you can work in almost any environment, including indoors. They are inferior to models with a gasoline (diesel) drive in terms of power and autonomy.
	petrol/diesel	Powerful industrial vibrators with a high degree of mobility.
	pneumatic	The use of a compressor is relevant for the most part in the conditions of reinforced concrete plants.
Power	low and medium power	up to 2000 W. Household or for local use in construction. Lightweight, portable, affordable.
Power	professional	2000-4000W. Adapted for continuous use when pouring reinforced concrete products and monolithic construction, designed for continuous operation.
Frequency and amplitude of vibrations	low frequency	up to 3.5 thousand vib / min. Due to the low frequency and large amplitude of vibrations, they are adapted to work with slow-moving coarse-grained concrete varieties.
	midrange	from 3.5 to 10 thousand vib / min. The most versatile option if work is carried out with concrete of varying degrees of mobility.
	high frequency	more than 10 thousand vib / min. It features a high frequency and small amplitude of oscillations, due to which it is the optimal solution for mobile fine-grained concrete.
Weight	up to 6 kg	This parameter is largely determined by the scope of the units and depends on their power. The mass of portable household devices usually does not exceed 5-6 kg, while industrial equipment can weigh up to 100 kg.
	6-20 kg
	over 20 kg

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

Data for selection of immersion models

Parameter	Meaning	Note
Shaft length	0.5-20 m	The length of the shaft is selected based on the thickness of the concrete mixture with a margin of 1 m. This simple rule is dictated by common sense and the efficiency of using equipment in various conditions. Long shafts up to 15-20 m in size are used for pouring reinforced concrete supports, 2-5 m is usually enough for pouring foundations, and short ones (0.5-1 m) for sealing floors.
Club diameter*	25-110 mm	The diameter of the vibrotip (club) is selected based on the density of the reinforcement. Usually, for reinforced structures, 25 mm products are preferred, but if the reinforcement is rare or not used, then a tip of 76 mm or more can be used, because. in this case, the efficiency of vibrocompaction increases, and the complexity of the process decreases.

* note that the handpiece gets very hot during operation - this is normal, just be careful.

Well, if you decide to purchase a surface vibrocompactor, then when choosing, you need to take into account the following features, which for the most part relate to equipment.

It should be noted that the effective range of both those and other equipment options usually does not exceed 0.5 m. This suggests that the step of rearranging the internal vibrators should not exceed this value.

Accessories and spare parts

For the most part, this question concerns submersible type equipment, in which flexible shafts and tips are consumables. Most often, the manufacturer offers a set of shaft and mace 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.

5. Red Lighthouse IV-98E - from 10,000 rubles.

In our review, we have already met the products of this plant, but you can’t get past the platform-type model Krasny Mayak IV-98E. Such equipment is attached to the formwork or intermediate structure, the main thing is that the axis of the vibrator is horizontal. Despite its purpose, this is a fairly compact design in a rugged steel housing that provides protection for the motor, shaft, weights and other components. In addition to being used for compacting concrete mixtures with a high density of reinforcement, IV-98E can be used in the manufacture of vibrating tables, vibrating plates and other equipment.

This equipment is arranged similarly to the IV-99B, presented in the video below.

6. Wacker Neuson AR 36/3/230 - from 18,000 rubles.

The Wacker Neuson AR 36/3/230 model is a kind of alternative to the above product from a domestic manufacturer. This is a German brand with production in Germany. It costs more, but it is he who is trusted by the largest construction companies building facilities around the world. It is economical and durable, can work in two axes without the risk of damage to the drive. Mounting on the formwork is not included in the kit - this must be taken into account before purchasing the vibrator. The cost of a proprietary mount can reach half or more of the cost of the vibration equipment itself.

The operation of such vibrators is clearly demonstrated in the following video.

7. Wacker Neuson AR 64/3/400 - from 70 thousand rubles.

If the equipment must work for wear for the longest possible time, then you need to focus on a professional vibrator model such as Wacker Neuson AR 64/3/400. This equipment is equipped with an electric motor powered by a three-phase network, the design of the unit provides for convenient installation and maintenance. Works on the basis of the same equipment as the previous product. Summarizing the above, AR 64/3/400 in the amount of several pieces will suit construction companies for the construction of reinforced concrete walls or precast concrete plants.

8. Makita BVR450Z - from 13,000 rubles.

The name of this brand is familiar to many who at least once held a high-quality power tool in their hands - the Japanese Makita is valued for its excellent quality and adequate cost. The Makita BVR450Z internal vibrator model is notable for the fact that this portable device is powered by a battery. Sometimes it is very convenient not to be tied to an extension cord. The length of the flexible shaft is small, which hints at a rather limited use of the tool, for example, when pouring floors, screeds, shallow strip or slab foundations. However, we immediately warn you that by default the product is not equipped with a battery - it will have to be purchased separately, and this is another plus of 5-6 thousand rubles.

By tradition, we offer you to watch a short review of a similar model in order to get a complete picture of the Makita BVR450Z vibrator.

9. Grost VGB 4000 W - from 17,000 rubles.

The review of vibrators for concrete would be incomplete if we bypassed such an autonomous solution as the Grost VGB 4000 W. This is a petrol drive supplied without a flexible shaft and a mace, the cost of which will be another 5 to 7 thousand rubles. depending on their size. Those. for a maximum of 25 thousand rubles. you can get full-fledged equipment for work in conditions of lack of power supply. Although more often it is purchased for convenience, because in this case there is no need for a long extension cord or the use of power generators. If anyone is interested, Grost is another good China with Russian roots. A simple device, high power and durability - what else do you need from high-quality equipment?!

If you have some components, as well as skills in working with tools, it is quite possible to make a homemade vibrator. Here you will not find super-detailed drawings - with the help of simple diagrams, we will simply give you ideas about the future design.

Important! As practice shows, in the absence of all or most of the equipment necessary for the manufacture, it is better to abandon homemade products in favor of a factory product. It's faster, more reliable, safer.

From the lawnmower

The drive of the future vibrator can serve as a motor from an electric lawn mower. Those. the issue was initially resolved with the third piece of equipment. It remains only to deal with the flexible shaft and mace. The figure below is something like a drawing-scheme of a submersible product.

The vibrotip can be made from two pieces of pipe of a suitable diameter. For these purposes, close one end of the pipe with a plug or weld. Install a bearing in size and an eccentric inside the pipe, the parameters of which will affect the amplitude of oscillations.

The eccentric can be machined on a machine or made from a conventional shaft by welding a rod to it on one side. A minimum of two bearings are required to ensure proper operation of the mace. With the second bearing, fix the eccentric, the tip of the shaft of which can have a different geometry for its connection through the head to the tip of the trimmer head of the lawn mower. To the latter, the connection is made through a bolt and a head according to its dimensions. The junction is hidden by the second part of the pipe from the tip. Protect the scythe cable with a strong hose, which is attached to the mower and handpiece with clamps. The video below shows just such an instance in finished form.

Checked - it works!

From an unnecessary electric motor

You definitely have something to replace the factory vibrator with an unnecessary electric drive. For example, from a pump, washing machine, etc. 3000 rpm will be enough for these purposes. Below is a diagram of a homemade product.

The whole secret is to securely attach the tow rope, which will transmit torque to the eccentric in the vibrating tip. To do this, it is necessary to drill two holes in the protruding part of the drive shaft: insert the cable into one, and the bolt into the other, with which this cable will be fixed. Now this part must be protected from dirt and moisture in order to avoid damage to the cable and drive. Make a kind of casing from a pipe of a suitable diameter, making several longitudinal cuts on one of its sides and shaping it into a cone shape. The gaps will subsequently need to be welded. Put a strong thick-walled hose on the casing, inside of which there will be a rotating cable. The hose is fixed with a clamp connection.

Make an eccentric and fasten it to the cable in the same way that the cable was connected to the drive shaft. Use a pipe of the required diameter with one soldered end as the body of the vibrotip. Place two bearings and an eccentric inside the pipe, weld a protective cover on the other end.

The video below shows the result of the work done. Checked - it works!

Nozzle for puncher or drill

It is also possible to adapt an ordinary drill to compact the concrete mixture, which will serve as a much-needed drive. The power of the drill will determine how long the flexible shaft can be made. A diagram of such a device is shown in the figure below.

To transmit torque in homemade vibrators for concrete, a tow cable is traditionally used. If the length of the shaft does not matter, then a steel rod can also be used, at the end of which unbalances are welded. Fix the cable to the drill with a chuck. Use a rigid hose of a suitable diameter, inside which this cable will rotate, securing it to the drill with a clamp. Attach an eccentric to the other end of the cable. For these purposes, drill a couple of holes in it, in one of which place the cable, in the other - a bolt to fix it.

Now it remains to make the body of the vibrator tip and our homemade deep vibrator will be ready. Make the body out of two parts: take a pipe of a suitable diameter, plug it on one side, insert a pair of bearings and an eccentric as in the diagram above. Protect the junction of the cable with the eccentric with a casing made from a pipe cut, as shown in the previous example. Weld the two parts of the mace and connect the tip to the flexible shaft shell.

It is no secret that concrete becomes truly durable only after the painstaking work of the builders. In hot weather, he needs protection from drying out, in winter, insulation and electrical heating. But the building codes require the use of a deep vibrator for concrete at any time of the year when pouring massive structures (foundations, columns, ceilings). Without this device, the strength of artificial stone is reduced by at least 20%, which creates a real danger of destruction of critical parts of the building.

In private construction, concrete goes not into thousands, but into tens of cubic meters. However, an immersion vibrator is necessary here as well.

Why do you need a deep vibrator?

The structure of freshly prepared concrete (granulometric composition) is very heterogeneous. It contains large gravel and fine sand, cement milk, water and air. If you just "plunk" the concrete mixture into the formwork, nothing good will come of it. Air pockets will reduce the strength of hardened concrete, and crushed stone and sand need compact packaging.

The construction vibrator makes the concrete mix flowable by setting its solid particles in motion. As a result, air is squeezed out to the surface, and the filler is evenly distributed inside the structure.

The one who used this tool noticed that the vibrated concrete literally sits in the formwork before our eyes and its original volume is reduced by almost a third. After such processing, the main enemy of concrete - voids disappear, and its strength reaches the normative maximum.

How does a concrete vibrator work?

The key condition for creating vibrational oscillations is an eccentric shaft rotated at high frequency. In a deep vibrator, it is located in a mace (vibrating tip) - a massive steel cylinder fixed at the end of a flexible shaft. The motor rotates the vibrating shaft through a steel cable covered with a plastic or rubber sheath.

Vibrotip device

Working with a deep vibrator is easy. Having immersed the vibrator head in fresh concrete, the device is turned on and the mixture is compacted until it stops settling in the formwork. After that, the tool is alternately immersed in adjacent sections of concrete, repeating the workflow.

Varieties of deep concrete vibrocompactors

There are four types of power plants that activate vibrations of the vibrotip: an electric motor, a gasoline and diesel engine, and an air compressor.

Electric internal vibrators are used more often than others, since most construction sites have a central power supply.

Petrol and diesel submersible vibrators are completely autonomous and indispensable at facilities located far from power lines.

Petrol internal vibrator

Pneumatic installations are not widely used in private construction.

In recent years, cordless immersion vibrators have appeared on the market. They are not inferior to gasoline in terms of autonomy, but much lighter and more compact.

Battery deep vibratory compactor

In the Soviet period, construction sites used vibrators operating in the same frequency range. Today on sale you can find devices that create vibration vibrations of low, medium and high frequencies, as well as multi-frequency installations. This gradation is due to the fact that the concrete mixture contains particles of different weight and size. For their optimal compaction, different vibration frequencies are required.

According to the type of alternating voltage used, electric deep concrete compactors are divided into two types: three-phase and single-phase. The former are more powerful and belong to the category of a professional tool. The latter are indispensable in individual construction, where there is no three-phase power line.

Main characteristics and features of choice

The first indicator that you need to pay attention to when choosing a deep vibrator is power. The time of continuous operation of the tool depends on it. For domestic needs, 750-1500 watts will be enough. To work on a large construction site, you will need a vibrocompactor with a power of at least 3-4 kW.

The second operating parameter is the vibration frequency of the tip. For compacting fine-grained concrete, high-frequency devices (vibration frequency from 10,000 vib./min.) are optimally suited. Their oscillation amplitude is very low. This combination of frequency and amplitude allows all concrete particles to be compacted as compactly as possible.

For concrete mixtures of large fractions, it is better to use low frequency internal vibrators (up to 3500 vib./min.).

For use in home construction, it is better to buy a portable vibrator for concrete of medium frequency (3500-9000 vib./min.). It works equally well on both fine-grained mixtures and concrete with coarse gravel.

The second indicator is the weight of the device. For private construction, a manual electric vibrocompactor is optimal. You can work with it without an assistant. This tool takes up minimal storage space and is easy to transport.

The weight of the manual concrete compactor does not exceed 6 kg. More powerful vibrators weigh about 20 kg. They are used by small construction teams. To work on professional equipment (weight up to 100 kg), several people are needed, and a sufficiently large car is required to transport it.

When choosing a submersible vibrator, you need to pay attention to the size and length of the working tip. For compaction of reinforced concrete, it is better to buy a vibrator head of small diameter (25-50 mm). For work with non-reinforced concrete, a vibro-tip of a larger diameter (up to 110 mm) is optimally suited. It will compact the mix better and faster than a thinner vibrator head.

To work in deep formwork (filled piles, columns, high grillage), the length of the flexible shaft of the virator is selected from the following calculation: formwork height + 1 meter.

How to make a deep vibrator with your own hands?

Despite affordable prices, many craftsmen try to make a vibrator for concrete with their own hands. The simplest method is to adapt a construction hammer for vibrocompaction. It cannot be called very effective, but such a device at a construction site will bring some benefit.

The idea of the alteration is to install a standard peak with a metal thrust plate welded to it on a 1.5-2 kilowatt puncher. To vibrate concrete, the plate is applied to the formwork and the tool is switched on in the impact mode. The pushes of the lance through the formwork are transferred to the concrete. For deep compaction, the peak is immersed in concrete and “bayoneted” it, periodically raising and lowering the perforator. Obviously, only concrete, the thickness of which is equal to the length of a steel rod, can be compacted with such a primitive mechanism.

For deeper compaction, craftsmen create home-made vibrating nozzles for drills, grinders, hammers and lawn mowers. The basis of such structures is a steel pipe in which a self-made eccentric shaft is mounted on bearings. Through a coupling, it is attached to a flexible steel cable rotated by an engine.

The tip of the tool must be inserted into the concrete vertically, without horizontal movement.
The distance between the injection points must not exceed 5 vibrator head diameters.
The duration of compaction depends on the power of the tool and the consistency of the concrete mix. The optimal cycle time is from 10 to 20 seconds (vibration is stopped at the moment the cement laitance appears on the concrete).
The vibrotip during operation should not touch the reinforcement and formwork.
The vibrator is removed slowly, with oscillatory movements up and down. This is necessary to prevent air from entering fresh concrete.
