Make a vibrator for concrete with their hands

When pouring monolithic concrete structures to seal the solution and removal of it voids and air bubbles are used for concrete vibrator.On the market there are many models of vibrators and their purchase is justified if you plan to fill large volumes of concrete.But what if the foundation dimensions are not so great, and the purchase of equipment would negate the whole economy?The answer is simple: a vibrator for concrete can be done with his own hands from the available tools and materials residues.

Concrete Vibrator

Vibrator for concrete

How does a vibrator?

principle of its operation is based on the removal of air bubbles from the solution with stirring.Concrete poured into the formwork with the valve, manually mix is ​​very difficult, and sometimes impossible.Penetration layer of concrete with a metal rod is ineffective.It is therefore necessary device which can be immersed to a sufficient depth and to give it a high-frequency vibration.That device is a homemade vibrator for concrete.Due to vibrations with a high frequency vibrator mixing solution, wherein air bubbles are lighter than the concrete quickly rise outward.Concrete Column Monolithic, water-resistant, has no internal stresses, shells and weaknesses exposed destruction.

In the video presented concrete vibration process, while seen as sealed and deposited solution.

homemade vibrator for concrete from Punch Punch

working in strike mode, reciprocating motion with high frequency.When attaching the nozzle to it as rebar spikes or desired length he can with sufficient effectiveness to break concrete thickness, making it easy to fill the vertical structures such as piles in the pile foundation.The main requirement for the packing - sufficient length.

When using the punch to vibrate the concrete in horizontal structures it is fixed to the formwork so that the nozzle is at a slight angle to the horizon.This can be done with a steel washer of suitable diameter, mounted on formwork.The washer nozzle is inserted into the punch and include it for 2-3 minutes.So come with all areas of the poured concrete.

homemade vibrator for concrete from drill

more complicated, but also more convenient model homemade vibrator of drill can be used for pouring monolithic concrete structures.Its principle is to convert the drill shaft into vibrations.This effect is achieved by an internal nozzle with an offset center of gravity, placed in a sealed tube segment of the sleeve.

role played by internal packing steel rod of circular cross section, with a diameter of 10-14 mm.Rod length is dependent on the depth of immersion vibrator, while aware that an increase in the length of the rod vibration force.By rod welded weighting, biasing the center of gravity, it can be made from a rod of rectangular or square section length of 10-15 cm. The weight material is welded along the bar at the end.

rod is placed in a flexible hose with waterproofing properties - it is necessary to eliminate the ingress of concrete core.Vibrator is a sleeve of spetsstalnoy pipe diameters from 30 mm to 50 mm, sleeve length - about half a meter.On one end of the tube brewed or close a suitable stopper.On the other end of the pipe sleeve mounted with the bearing, put on the inner core.The length of the rod within the sleeve must be such that during rotation of the rod it strikes the wall and create vibration.

regulation of the oscillation amplitude is achieved by changing the number of revolutions of the drill.The drill must be designed for continuous operation, optimally select the device with a capacity of more than 650 watts.

Homemade vibrators for concrete may well replace the purchase unit by pouring a small base, their production will help you to reduce the costs for the construction and purchase of equipment.
