Production of a solid vibrating table for the production of paving slabs. DIY vibrating tables for paving slabs

Manufacturing technology of a homemade vibrating table for paving slabs will be useful to those who plan to paving paths in the courtyard of an individual house. As well as private entrepreneurs who are ready to organize a mini-production of tiles and paving stones for sidewalks and paths.

Paving slabs are a sought-after material, both for utilities and private homeowners. Easy to install, resistant to abrasion, low maintenance and other advantages of tiles have led to its growth in popularity.

Many, deciding to lay a tile on a large area, independently take on its manufacture.

Do-it-yourself vibrating table for paving slabs

The main equipment you need to buy to get started
tile manufacturing process is a vibrating table. It is designed to seal
the composition of the tile mold and the removal of air bubbles from it.

However, master craftsmen also act independently here,
preferring to make a vibrating table with your own hands, rather than buying a ready-made one. Tem
more than that, you can make it from improvised means at home.

We will try to consider in detail how to make a vibrating table
with your own hands, in the form of step-by-step instructions.

What is a tile vibrating table?

Vibrating table or vibropress is the production equipment
paving slabs. The working surface of the table can make oscillatory
movement, such vibration is its main advantage and
purpose.

The vibrating table allows you to make not only paving slabs, but
and cast concrete sections of the fence, monuments, decorative elements, etc.

Vibrating table for tiles - types and types

To determine the type of future equipment, you need
understand what vibrating tables exist and what is the purpose of each type:

1. Direction of vibration:

Vibrating table with horizontal vibration;Vibrating table with horizontal vibration

Vibrating table with vertical vibration Vibrating table with vertical vibration

The direction depends on how the rotor will be mounted.
The most widely used tables with horizontal vibration.

2. According to the installation method:

  • mobile (portable);
  • stationary.

3. By specialization:

  • molding. Tables are intended for product formation;
  • stripping (forming stripping). Purpose - knock out
    (remove, shake out) the product from the mold using vibration.

Shaping vibrating tableSuch vibrating tables have almost the same appearance. They are distinguished only by the nozzle with holes installed on the forming table.

A mold with a product is installed on such a nozzle and it is removed from the mold by means of vibration.

The appearance of the table is shown in the photo.

Drawing of a forming nozzle for a vibrating table For individual construction, it is enough to make one vibrating table with horizontal vibration. And removing tiles from molds is not
labor, since flexible forms are usually used in private production. Tem
moreover, you can install the forming nozzle at any time.

The drawing-scheme of the forming nozzle is shown in the picture.

The material was prepared for the site www.moydomik.net

In practice, a vibrating table made for the production
paving slabs at home, most often used as a base
for cutting machine or as a platform for mounting a circular saw.

The principle of operation of the vibrating table for tiles

To understand which parts / structural elements
will be needed for work and why each of them, we will briefly describe the principle of operation
vibrating table.

The design of the vibropress for paving slabs (device)

The working surface is fixed on the frame by means of
using a spring system (for horizontal vibration) or hangers (for
vertical). The tabletop is driven by an electric motor, calculated
power with an eccentric on the shaft. The task of the eccentric is to shift the center of gravity
engine to provide the desired vibration.

A sketch of the vibrating table is shown in the figure.

Tile vibrating table dimensions

  • countertop dimensions it is advisable to make 600x600 or
    lengthen one or both sides. Doing them already is impractical, because. at
    vibrating forms tend to move and they need to be constantly “caught”
    or install less and place strictly in the center. Table too narrow
    reduces the performance of the vibrating table and is quite unstable
    design.

Note. The dimensions of the vibrating table are also affected by the planned
the volume of production, the larger it is, the larger the dimensions of the countertop should be. IN
in turn, the increase in the dimensions of the tabletop puts forward increased requirements for
the material of its manufacture, the stability of the frame and engine power.

  • vibrating table height. Calculated based on physiological
    parameters of the person who will work at the table. With an average height
    a comfortable height is 900-1000 mm.

Note. When deciding on the height of the table, consider how it
installation. If the legs of the table will be dug in and cemented, they need to be made
longer. If the design is mobile, this height is enough.

Tool:

  • welding machine;
  • drill;
  • Bulgarian.

Table materials:


The cost of plywood brand FK 15 mm birch veneer
(sheet dimensions 1,525 x 1,525) - 650 rubles.

The cost of hot-rolled metal 5 mm thick
(sheet dimensions 1,500 x 6,000) - 10,870 rubles.

Note. A thinner sheet should be reinforced with metal
pipe or corner, welding them around the perimeter and in the center.



  • metal tubes for leg supports- 40x40 with a thickness of 2 mm (107 rubles / m.p.);


  • plate for installation of electrical equipment;

For your information. The cost of a spring with a diameter of 53 mm, a height of 113
mm. for a scooter is 500 rubles.


Note. With a glass diameter significantly larger than
diameter of the spring will cause uneven vibration and wear of the springs. BUT
the tabletop will sway, not vibrate.

  • bolts and washers (4 pcs). Designed for engine mounting;
  • electrical cable of sufficient cross section, socket,
    switch, automatic switch;

Which engine is better for a homemade vibrating table?

Users advise to use for private production
paving slab vibrating motor:

  • IV-99 E (7650 rubles): power 0.5 kW, power supply - 220
    B, weight 14.5 kg, driving force up to 5 kN, vibration frequency 3000 rpm.
  • IV-98 E (8540 rubles): power 0.9 kW, power supply - 220
    B, weight 22.5 kg, driving force up to 11 kN, vibration frequency 3000 rpm. This
    the vibration motor is distinguished by the presence of unbalances installed on the rotor. revolving with
    rotor shaft, they create a driving force.

For industrial production, a vibrator is suitable
IV-104 B: power 0.53 kW, power supply - 380 V, weight 25 kg, forcing
force up to 6.3 kN, vibration frequency 1500 rpm.

Note. It is important to ensure uniform vibration. Otherwise,
there is a high probability of boiling of the cement mixture in the molding containers. Those.,
instead of compacting the mold composition, vibration will saturate it
air, which will lead to the fragility of paving slabs.

The easiest and most economical way is to use the old
engines from a washing machine, pumping station, etc., which will cost much
cheaper within 1 thousand rubles. + turner (shaft (axle), eccentric, holder for bearings).

How to properly assemble a vibrating table

  1. Before assembly, it is desirable to process metal parts
    anti-corrosion solution that prevents the appearance of rust. For example,
    primer GF-021 LAKRA (125 rubles / kg) or enamel-paint "Spetsnaz primer-enamel according to
    rust" (383 rubles / 0.8 kg). For a metal that is already touched by corrosion, you need
    use special primers, such as primer EP-0180 (188 rubles / kg).
  2. The components of the vibrating table are connected by a welded seam.
    The choice of a rigid mount is due to the fact that the bolts during vibration can
    loosen and reduce the rigidity of the support. If you need to make a collapsible design
    bolts are used, which must be periodically tightened.
  3. The motor driving the vibrating table must not touch
    earth. After installing it, it is advisable to make a trial run
    equipment in order to test the oscillation amplitude, stability
    design and stiffness of the springs.
  4. The length of the legs of the support must be the same. In addition, the place
    the installation of the table must be even so as not to create a distortion during installation
    vibrating table. It is reasonable to fix the table motionlessly on the base. Or using
    concrete mortar or with anchors.

Conclusion

The device of the vibrating table is a relatively difficult task, however
less, it can be done with your own hands, practically from improvised means or with
minimal costs (if you do not take into account the purchase of an electric motor, although,
You can also buy used. This approach is expedient in conditions of a large front.
work or, if you wish, to organize a small business for the production of paving
tiles or paving stones.

For quality workmanship do-it-yourself paving slabs or sections of a concrete fence, you need a vibrating table, which you can purchase, or you can do it yourself. It is easy to make and economically justified. Most of the materials for it are in any workshop or garage.

Studying the prices of paving slabs and concrete fences, many decide to make them on their own. Firstly, it is profitable, and secondly, you can make good money on subsequent production, especially if you live in an area with a large number of new buildings and empty lots. To implement the idea, it is enough to choose the forms and make a vibrating table.

Nuances in preparing for work

Despite the fact that all methods for manufacturing a vibrating table are similar in many respects, there are nuances that need to be clarified at the stage of creating a drawing. In order not to have to redo everything after launching, we will analyze the main ones.

We select the engine

A special vibration motor can be purchased at the store, but it is not cheap. Most people prefer to buy washing machine motors from friends or find suitable option in the garage. In general, you can rely on such indicators: for large tables weighing 200-250 kg and a tabletop length from a meter to two - an engine from 0.75 to 1.1 kW. For small vibrating tables up to two hundred kilograms and 1x1 meters in size or less - with a power of 0.23 kW.

Do not forget that low-power motors are not designed for mass production and can withstand about 30 cycles, after which the bearings will have to be changed, and the axle may also become loose.

What material to choose for the countertop

Most often, metal is used, since it is easier to clean it from the solution, but in our example, an option with an OSB plate will be shown. The material was not chosen by chance, the main goal was to facilitate the design. The plate does not carry a structural load, but serves only to protect the engine and the vibration mechanism from getting a solution on them, so there is no need to make it from metal.

When choosing a metal, pay attention not only to the dimensions, but also to the weight of the plate. If the engine is powerful, and the tabletop is made of thin metal, it can be torn off or bent. If thick metal and a motor from a washing machine are selected, its power will not be enough to create the desired vibration.

Base shape

Factory tables rest on four legs, in our example an H-shaped base will be shown. In terms of strength and stability, it is not inferior to the classic form, but in this way it was possible to achieve a convenient approach from any point. When dragging mortar or tiles, a person does not cling to partitions, and the cost of manufacturing is significantly reduced. With the classic version, you have to cook not only the frame, but also strengthen it with cruciform planks.

For the manufacture of sections of fences, you will have to make an oblong vibrating table, a little more than two meters long, and a small one, up to 50x50 cm, is suitable for tiles. Everyone selects the height according to their height.

Springs or rubber pads

For the manufacture of a vibrating table, rubber cushions or springs are used. If the table is made for itself and runs on a low-power motor, you can put rubber cushions. For large tiles or fence need springs.

With strong vibration, the plate collides with tight rubber. These blows will eventually destroy not only the pillow, but also the countertop itself. In addition, the blows are transmitted to the frame and if the platform is not welded onto the legs, they will break the floor or enter the ground unevenly.

Springs can be obtained for free by asking your friends. Others simply buy springs from a moped or car on the market and cut them in half. In height, they should be between 8 and 12 cm. Soft springs create less noise, but can compress a lot. Given that they are selected empirically, it is better not to risk it.

To check whether the springs are suitable or not, in the assembled state, load the platform with a weight twice the planned load. In this state, the countertop should not come into contact with the glass under the springs.

Two motors or one with eccentric regulation

There is a situation when a person found two old motors from washing machines and decided to install them on a vibrating table. Such engines will work normally, provided that they are exactly the same. Otherwise, a different frequency will lead to the “boiling” of concrete.

Some deliberately take this step, planning to control the strength of the vibration, turning on one or two motors at the same time. It is better to purchase one powerful and regulate the strength with eccentrics, this will reduce the percentage of marriage.

Tools and materials for the manufacture of a vibrating table

Since the vibration mode is very aggressive, the material for the future table must be chosen with a margin of safety.

To make a vibrating table you will need:

  • 12 meters profile pipe size 100x80 mm;
  • quarter square meter metal sheet 12 mm thick;
  • round steel with a diameter of 40 mm and a length of 400 mm;
  • round steel with a diameter of 100 mm and a length of 150 mm;
  • four bolts 20x100;
  • self-tapping screws for metal;
  • engine 2800 rpm per 1 kW;
  • machine;
  • cable.

Necessary tools for work:

  • Bulgarian;
  • a set of locksmith tools;
  • square;
  • ruler;
  • electrodes;
  • cutting circles.

Step-by-step instructions for assembling a vibrating table

For the base, we cut six pieces from a pipe 100x80, 600 mm long and one two-meter piece. For the upper movable plate, we cut off four pieces from a 100x80 profile pipe with a length of 440 mm and two pieces for 2200 mm. From a sheet 12 mm thick we cut off a rectangular piece measuring 600 by 400 mm.

Now let's start assembling. Let's start with the base, which consists of two H-shaped supports, set on one side and rigidly connected to each other by a crossbar by welding, from pipe sections 600 mm long.

Screws 20x100 are installed on the lower horizontal of the supports to adjust the level of the table. On the top, 6 pieces of pipe 1 cm high and with a diameter for springs are welded.

Springs from the engine valves of a ZIL car or any other heavy vehicle are well suited for this. Pieces of tubes are welded in three pieces for each support. The tubes act as cups for the springs.

The upper plate of the vibrating table is a rigidly welded rectangular frame, along the edges of which sections of a profile pipe 2200 mm long are interconnected by pipe parts 440 mm, at equal distances from each other.

A 12 mm sheet, 600x400 mm in size, is welded to the frame in the middle, on which the vibration motor is mounted. Along the edges of the frame, the same nests for springs are welded as on its lower part. The sockets on both sides must be placed strictly opposite each other so that the springs inserted into them stand vertically.

The peculiarity of this table is that the vibration occurs in a horizontal plane, excluding the boiling of the mixture. That is why the vibration mechanism must be made independently, and not installed by the factory, in which the vibration is vertical.

The vibrator mechanism itself consists of a cage for bearings and a hollow cylinder. Bearings are installed at both ends, and the cylinder itself is welded to the plate on the upper half of the vibrating table.

1 - cylinder; 2 - holders for bearings; 3 - bearings; 4 - shaft; 5 - eccentrics; 6 - pulley; 7 - nut

A shaft is pressed into the bearings, on which a pulley is put on, and already two eccentrics are installed on it, which are attached to the pulley with six bolts. Since the bolts are arranged in a circle at the same distance, this makes it possible to rotate the eccentrics in relation to each other, thereby adjusting the vibration force. All this is fixed with a nut screwed onto the threads in the upper part of the shaft.

On the opposite side of the plate, a flanged electric motor is mounted with four bolts. A pulley is pressed onto the motor shaft. The rotation from the engine to the vibration mechanism is transmitted by means of a textile belt. All this is covered OSB slab, sawn to the size of the table.

That's basically it. The table has been tested quite well, during the year about four hundred tons of concrete were vibrated on it, there were no breakdowns or failures during this time.

Common manufacturing mistakes

Some put the springs not in glasses, but put them on steel fingers. When vibrating at the moment of pressure, they can walk slightly in different directions. Such an uneven load quickly wears out the springs.

The tabletop is framed around the edges so that the forms do not move out onto the floor, but one corner should be bent to drain. Then you do not have to pick out the remains of the solution with a trowel.

To determine where to weld the glasses on the frame, you can lubricate the springs with grease and press the frame against them, then marks will remain on its surface.

Take your time and do everything with high quality, then the equipment can be sold and get much more money than was invested. Thus, you will not only save on tiles and fences, but also recoup some of the material spent on their manufacture.

Implementation of the idea of ​​own production artificial stone or paving slabs start by defining a list necessary equipment. The most expensive purchase will be an electric vibrating table. Do-it-yourself manufacturing will reduce financial investments in your own business.

It is a product for paving walkways, playgrounds in parks and around houses. The material is:

  • Concrete.
  • Rubber.
  • Natural stone.
  • Clinker clay.
  • Wood.

The most affordable is the manufacture of concrete by vibrocasting or vibrocompression. In both cases, the molds with the solution are installed on a vibrating table with an electric motor - a device that performs oscillatory movements. Vibration provides:

  • strength;
  • removal of air bubbles from the mixture, compaction;
  • homogeneity.

Main elements:

  • The base is a structure for fastening the table top.
  • Vibrator - an electric motor with an eccentric mounted on a shaft.
  • Tabletop - frame with sheet material(metal, chipboard, fiberboard).
  • Shock absorbers - a unit designed to transmit vibration.

How to assemble a vibrating table yourself?

The embodiment of the idea begins with the creation of diagrams, drawings with dimensions.

1. Making the base.

As a support are used:

  • Welded metal profile construction.
  • Car tires.
  • Washing machine.

Metal frame - welded from a corner, a square (rectangular) pipe, a channel. Optimal size section: 50-80 mm, depends on the dimensions of the table, the total mass of the molds filled with the mixture.

The height of the bed is selected, taking into account:

  • Operator growth.
  • Installing the table on the foundation, pedestal.
  • Digging into the ground.

The width and length of the base is equal or slightly, downwards, differs from the dimensions of the countertop. Dimensions are made in accordance with the parameters, the number of molds for paving slabs in one batch.

2. Choice of vibration device.

To make a motor with an eccentric on your own or purchase a finished product is up to the master to decide. Making from an engine lying around in a pantry or garage is suitable for a one-time production of a small batch of paving slabs. Production on an industrial scale will require the use of more reliable electromechanical devices with the ability to adjust the frequency of oscillation.

The modification of the vibrator is selected according to the mass, dispersion, number of batch forms:

Vibrating device mounting methods:

  • To the vibrating table top.
  • To an additional horizontal plane from a sheet of metal or a channel.

It is more convenient to mount on a welded channel or a rectangular pipe. When purchasing a vibrator, carefully read the instructions. Compliance with safety requirements during operation will reduce the likelihood of unforeseen, dangerous situations for the operator's life.

3. How to make a countertop?

Horizontal plane for placing forms with concrete mix can be made of durable sheet material:

  • Most often, metal with a thickness of 6-10 mm is used.
  • The use of plywood, chipboard, OSB will save money, but will shorten the service life.

The side along the edge will prevent slipping, falling forms. The design differs depending on the type of depreciation. The tabletop in drawing No. 2 provides an additional frame for fastening belts, chains.

4. Installation of shock absorbers.

Vibration damping is necessary to reduce the transmission of vibrations from the tabletop to the base, increasing the amplitude. Types of shock absorbers:

  • Steel springs for automobiles are new, used. They are installed on a piece of pipe, a bar welded to the frame. Quantity - from 4 pieces, in the corners. Glasses fixed to the tabletop are put on a spring, there is no rigid fixation (scheme No. 1).
  • Rubber - bushings, spacers. Fasteners, as in the previous version.
  • Frame hangers with tabletop - belt, chain, metal cable, tension spring. It is advisable to use for tables with horizontal (circular) oscillations (drawing No. 2).

The lack of a rigid mount is explained by the need to periodically change worn, deformed shock absorbers. The weight of the worktop does not allow the connection with the bed to be broken.

5. Technology of assembly of structural elements.

Homemade vibrating table can be attributed to production equipment. The requirements for its assembly and operation do not depend on the place of application: at home, at the factory. For the safety of the operator, perform grounding.

Assembly step by step:

  • Preparing the platform for the table. Compliance with the horizontal surface is mandatory.
  • The installation of the bed is carried out mobile or stationary. The choice of option depends on the need for movement during operation. Rigid fasteners are important for small-sized, low-weight options.
  • The engine and vibrator are mounted to the tabletop.
  • Springs (rubber bushings) are put on pipes (rod) welded to the frame.
  • The table top is placed on the base. Shock absorbers are located inside the glasses on the frame.
  • The surface is leveled horizontally using a level. This will ensure uniform distribution of concrete in the form, the correct geometry of the tile.
  • Conduct tests, adjust the amplitude of oscillations.

There are nuances that are important to consider:

1. The height of the table should correspond not only to the height of a person, but also to the way the forms are filled with concrete mortar. Take into account the large mass of the container for manual pouring of the mixture.

2. Large equipment may require the installation of 2 vibrators. In this case, it is important to avoid the occurrence of resonance.

3. Determination of the oscillation amplitude:

  • Fix the pencil on the surface, the stylus should protrude beyond the edge of the table.
  • Turn on the engine.
  • Bring a sheet of paper attached to a rigid base. The trace from the pencil will allow you to determine the amplitude.

4. To prevent corrosion, metal parts are coated with primer, paint or varnish.

5. Before buying, perform an analysis of the cost of the product, consider options for replacing expensive items with cheaper ones:

  • Replace a sheet of metal with plywood or a piece from old furniture.
  • Buy springs at car "collapses".
  • Replace the vibrator with an engine from a washing machine, use a hammer drill or impact drill.
  • Used tires can play the role of a bed.
  • Instead of a table, use the old washing machine in spin mode, with a cover in the tank.

6. Vibrating table with minor modernization can be used as equipment for screening bulk products (sand, cement).

7. Don't skimp on making tiles for sale. The higher the culture of production, the better the quality of the product, the lower the cost. It may make sense to purchase off-the-shelf equipment with fine-tuned process technology.

Having Vacation home, cottage or cottage with personal plot it may be necessary to equip paths, gazebos, paving yard paving slabs. If you have minimal building skills, desire and interest, you can make tiles yourself. As a result, you can get products that differ in original design, as well as significantly save money.

General characteristics of the vibrating table

For the manufacture of paving slabs at home, you will need raw materials - cement, sand, water, dyes. As well as a device for forming tiles - a vibrating table. In hardware stores you can buy a ready-made mechanism, it will cost between 20 - 70 thousand rubles. Prices vary depending on engine power, configuration and manufacturer.


Homemade vibrating table on springs

But if the goal self-manufacturing paving slabs is to save money and small production volumes are planned, then it makes no sense to purchase a vibration mechanism, you can easily make it yourself.

Homemade vibrating table is metal structure visually similar to simple table. Its upper part is attached to the frame with springs or glasses, making a gap. Thanks to the engine fixed in the lower part, the table is subjected to wave oscillations - vibrations, due to this, the cement mass placed in the molds is evenly distributed and air is removed from it.

In principle, in the manufacture of paving slabs, you can do without a table, but in this case the quality of the finished products will be low, and the slabs will not last long. Due to the air inside the mass, the finished plate will be fragile and short-lived.

Necessary materials

For independent production of a vibrating table you will need simple materials:

  • metal corner or pipes;
  • Metal sheet;
  • springs;
  • bolts;
  • electric motor;

Metal pipes or corners are needed to form the bed - strong frame, supports. The metal sheet will act as a countertop, so you should choose a sufficiently strong material with a minimum thickness of 8 mm. Springs are needed to provide a greater amplitude of vibration, they can be purchased from the aftermarket.

Moped springs are best, you will need two of them, they are large enough and you can cut each in half.


During the installation of the vibrating table, the following tools will be needed:

  • Bulgarian;
  • drill;
  • welding machine

With the help of a grinder, pipes or corners are cut in accordance with previously prepared drawings.

A drill will be needed to drill holes when installing the motor. And with the help welding machine the process of assembling all the details of the table into a monolithic structure is carried out.

Homemade vibrating table for paving slabs

How to choose an engine


In order to make a vibrating table for paving slabs with your own hands, you will need an engine. It can be the simplest, taken, for example, from a washing machine.

Power in this case is not the main indicator, it will be better if it is small. Main characteristic should become an eccentric - a device that provides vibration. If not, a household engine and the question of buying it becomes, it is better to buy a motor with an eccentric, for example, the IV-98 or IV-99 model. They are specially designed for installation on vibrating tables. You can buy such engines both new and used, they will cost 5 - 7 thousand rubles.

If you modify a household motor yourself, you will need a sleeve with a screw and a bolt that is attached to the threaded end. When fastening the bolt, it is necessary to ensure its mobility in the transverse direction.

Vibrating table assembly


Before starting the installation of the vibrating table, it is necessary to prepare drawings. Consider the height and length of the future table. In order for it to be convenient in operation, the height should not exceed 90 cm, length 1800 cm, width 700 - 1800 cm.

It is clear that the larger the area of ​​the countertop, the more forms can be placed on it, but the more table the more powerful the engine will be. Another important point - you need to decide what the table will be - portable or stationary.

Portable is better to make small dimensions, since it will also be necessary to ensure its stability. If a stationary mechanism is planned, you can safely expand the area, and for stability, dig it into the ground or concrete it.

When the dimensions are determined, you can begin to prepare the details. Four legs must be cut out of the metal corners using a grinder, their length will be in accordance with the drawings, 70 mm. You will also need two segments equal to the length of the table and two segments equal to the width of the table. The bed will be formed from them. Four legs and frame elements are welded together using a welding machine.

The next step in the manufacturing process of the vibrating table is the installation of the tabletop. The top cover should be made of a sheet of durable steel, and the bottom should have attachments for the motor. The lid must be movable, therefore it is attached to the bed with the help of springs or glasses.


Engine position at 45 degree angle

It is enough to place four springs at the corners of the table if the surface will have big sizes, you will need two more springs placed in the center. If there is no spring, you can use glasses, you can make them from pipe scraps. Glasses or springs are welded on one side to the tabletop, on the other - to the frame.

Next, you need to install an electric motor. There are a few things to keep in mind when doing this step. If you place the motor horizontally, then the vibration will go in the vertical direction, by placing it straight you get horizontal waves.

Therefore, the most optimal is the location of the engine at an angle of 45o. in this case, the vibration will propagate in both planes. It is necessary to mount the engine securely, since there is a high probability of its displacement during operation, under the influence of vibration.
When preparing drawings and assembling the vibrating table, it is necessary to compare all the details of the future load.

The working surface must support the weight of the molds with the finished cement mass. And the engine power must correspond to the total weight of the table. All elements must be securely welded, the frame must be rigid and durable.

To start a successful activity in the manufacture of paving slabs, more forms will be needed. They can be made from various materials- metal, plastic, wood. Forms can be purchased ready-made, or you can make it yourself, using your imagination to get an original design.

Video: Homemade vibrating table paving slabs

Paving slabs, or paving stones, are a beautiful, durable material that is used for arranging and decorating. garden paths, sites and interior yard. Everything would be fine, but, to my great regret, paving stones are not a cheap pleasure, but everyone wants to make their yard clean and pretty, so I had such a great desire. Buy paving stones required quantity I could not - it turned out to be too expensive, but to make it myself - easily. :) It is about how to make paving stones on my own that I will tell you in this article, fully illustrating the manufacturing process.

Actually, the technology for the production of paving stones, as well as its recipe, was found by me on the Internet, since there is more than enough information, and I set to work.

For the manufacture of such paving slabs, it is necessary to have cement, sand, a superplasticizer and, if desired, a dye.


In the store, I purchased several bags of 500 brand cement and a superplasticizer, it will increase the strength of the paving stones and increase its resistance to low temperatures.


Not a huge, of course, but quite a decent pile of sand, brought about a year ago from a local quarry, we left after the completion of the house.


And I decided not to buy a colorant-dye. To be honest, as for me, the difference between colored and gray paving stones is small, the color still turns out with a shade of gray!

As a vibrating table, without which the production of high-quality paving stones is simply impossible, it was decided to use an old Siemens washing machine, which has long served its time, but is still very much in working order. If anyone does not know what a vibrating table is for, I explain - with its help, the maximum compaction of the forms of any concrete elements is achieved, in our case paving stones, which become more homogeneous and, accordingly, strong.

I will tell you about the forms separately and in more detail. :)

When I shared the idea of ​​making paving stones on my own with my friends, some of them suggested that I make the molds myself. Some suggested putting together forms from old wooden planks, the second advised to use unnecessary containers - trays, vessels, etc., the third persuaded them to make the molds themselves from a special polymer. Of course, I am a girl with “hands”, but I didn’t dare to do this, I decided to purchase ready-made forms, they are quite diverse, so you can choose a form with a beautiful pattern that will be printed on the surface of the finished product, giving it a special charm and chic.

Buying molds was also not an easy task, for a start it was necessary to decide which molds I needed: rubber, capable of withstanding about 500 castings - manufacturing cycles, plastic, which will last about 250 cycles, or polyurethane, the service life of which does not exceed 100 castings . Rubber and plastic turned out to be quite expensive, and, given that I was not 100% sure of a successful outcome, I purchased ordinary polyurethane molds for making paving stones in the amount of 10 pieces.


I started the production of paving stones back in May, since the weather turned out to be favorable, and I continue to this day, I need a lot of paving stones. :)

Now I will describe to you in detail the technology for the production of paving slabs - paving stones. For one casting, to fill 10 molds, I needed 10 kilograms of sand, 5 kg of cement and 30 grams of superplasticizer.


I thoroughly mixed all of the above components in the usual manual way in a large plastic bucket, and only after that I began to add water in small portions, stirring the mixture until smooth - so that the solution was viscous.


At this stage, the main thing is not to overdo it with water, its excess will reduce the strength of the finished product at times!

In addition to the components listed by me above, fine gravel or screenings can be added to the mixture for casting paving stones.

In addition to the fact that gravel will add even more strength to products, its inclusions will visually make paving stones more natural - “stone”. The ratio of the solution in this case will be as follows: 30 grams of superplasticizer, 2 parts of sand, gravel and cement.


Before pouring our solution into the mold, it must be lubricated with a special emulsion. There are a lot of emulsions on the market for these purposes, but I took the advice of my old friend and processed the forms with ordinary dishwashing liquid - you can use any. I applied the liquid with a small brush, carefully distributing it in a thin layer over the entire inner surface of each form.

After all forms have been processed, they must be slowly filled with a solution. I laid the forms directly on top cover washing machine and, filling them in half, turned on the machine in the spin mode.


To slightly increase the vibration, I first put an old blanket in the drum of the washing machine. As soon as the machine began to vibrate along with the forms, I added the remaining solution to them, filling them completely. Such an impromptu vibrating table copes with its task perfectly, and the quality of vibrocasting made me very happy.


Then I removed the forms from the washing machine and, having laid them out on racks in the garage, covered them with ordinary plastic wrap to prevent excess moisture from evaporating. Only two days later I removed the paving stones from the molds, it is not recommended to do this earlier because cracks quickly form on the molds during operation.


In order to remove the paving stones from the mold, I lowered them for a few seconds into water heated to 80 ° C, this contributes to the expansion of the mold, as a result, the paving stones are very easy to remove.


The vacated forms were filled with a new portion of the solution, and the paving stones were laid in rows on a pallet left over from the acquired blocks.


The finished products were stored for the first 10 days under plastic wrap, all in the same garage, and then moved to the street and kept for another month to gain strength.

Naturally, it makes sense to make paving stones on your own only when you don’t need a lot of it, although the concept of “a lot” is different for each of us. :) But it was this method that turned out to be the most acceptable for me, especially since the work did not take me much time and I did it in the intervals between the main things and, most importantly, with great interest and pleasure.

To make paving stones with your own hands or not, everyone decides for himself, and I can only say that it is exciting, easy and profitable. I hope my small master class for the manufacture of paving stones will be useful for you, try it and brag about your results.

But how to make a vibrating table (I feel sorry for the washing machine !!!)

How to make it yourself, make such a simple homemade vibrating table from tires. It is very simple and accessible to almost everyone, if you want to make such a vibrating table for home-made paving slabs and other concrete products, you do not need such large tires and such a large piece of metal. For this you can use car tires from a passenger car and if you don’t have such tires, then this is also not a problem, you can buy them for a penny at any vulcanization, used tires are always mountains there and they will most likely just be presented to you. So we take three tires from passenger car and twist them together with bolts, three bolts for each connection of one tire to another. Then we need a piece of metal a little larger than the size of the tires, approximately as shown in the photo, such a piece of metal, if you don’t have it, you can buy it at scrap metal collection points, if they don’t have such a piece, then you can order it from them and they will give you it will be found in a few days and sold at the price at which the scrap metal itself is rented, at the rate of 1 kg. it is not very expensive and available to everyone. After you have found the ramps and a piece of metal, you need to weld a piece of the channel in the center to your piece of metal by welding, a piece of the channel can be bought there at the scrap metal collection point, as it was shown in the photo lesson above and drill four holes for attaching the vibration motor. Now you just have to find a used vibration motor, it can be not large, you can use a standard one, for example IV - 99E, such a used vibration motor can be bought at electric motor repair shops or ordered from them, they will find the vibration motor you need very quickly or you can look for such a used vibration motor on the Internet. After you find the vibration motor, you need to screw the vibrator to the mount, the channel that you welded to the metal sheet with bolts, it is best to find the old used bolts as well. they are much stronger and more reliable than new ones, also be sure to use a grower for the vibration motor mounting bolts, tighten the bolts well otherwise they will break. After that, it is necessary to connect a wire to the vibration motor, which must first be passed through a hole made in advance in one of the slopes, as shown in the photo of a home-made vibrating table. After you have connected the wire to the vibration motor, you can install your tabletop on the ramps, with the vibration motor at the bottom, so that it goes inside the ramps. All Your vibrating table is ready to go. For even greater convenience, you can scald your countertop with a corner along the contour, you can use it so that the forms with concrete do not shrink or fall during vibration.

Here, as you can see from everything described, it follows that a home-made inexpensive vibrating table for home-made all kinds of concrete products can be made very quickly and
not very expensive. In the future, if you no longer need such a vibrating table, you can sell it to your neighbors and return the funds spent on it. We wish you good luck and for everything to work out for you, we are also always ready to help and advise you, visit our professional forum and we will answer all your questions. Sincerely, Spirit.
