Owners of private houses often face small household repairs and construction, in which large volumes of concrete solutions are not necessary.

Such works as foundation pouring,plastering of walls, leveling of sidewalks and access roads, do not always require the use of expensive and large-scale concrete mixer - for them a household vibrator is quite suitable. You can make it quickly with your own hands, and there is nothing complicated in this process. By the way, with the help of such a simple construction, you can even make a paving slab, a cinder block and a curb. Of course, the unit for mixing mortar can be bought in a store or rented for a while, but a self-made vibrator will cost much less than a factory vibrator, and this will not affect the quality of the work performed.

What is it for?

The need for using a vibrator is explainedthe fact that any concrete solution is quite heavy and dense, because of what the air bubbles formed during mixing are not free to go outside. This makes the hardened concrete brittle and vulnerable before exposure to moisture and heat. In order to release these bubbles, and a vibrating device is needed.

Principle of operation

Concrete solution is poured into the desired shape, and inIt is immersed in a vibrator head that creates vibrations. Under the influence of waves, bubbles rise to the surface. For a vibrator, almost any engine that creates rotational movements is suitable. For example, the nozzle can be connected to an electric drill. In principle, in order to make a vibrator, one only needs to assemble a device that converts rotational movements into vibrational ones. The easiest way to do this is to shift the center of gravity - this will cause the appearance of waves.

How to make a vibrator yourself: step by step instruction

1. Nozzle

Do the nozzle is better made of stainless steel. The concrete solution itself is already an aggressive environment, and if it contains additional fractions such as crushed stone or slag, then even more so. A steel tube with a diameter of about 4 cm is suitable. Insert the rod about 1.5-2 cm in the cross section inside the tube. To the main rod we weld an additional rectangular one. This part will shift the center of gravity, so that vibrations are formed.

2. Assembly

With the help of bearings, fix the rod inside the tube. It should rotate freely. In one of the protruding ends, it is necessary to make a hole, to which the drive will be fastened.

3. Actuator

With the help of a bushing we connect the metal drive withattachment. The second end of the drive is fixed in the holder of the drill or perforator. The tool with the engine running can be fixed with a vice in the immediate vicinity of the treated solution or simply held in hands, directing the nozzle to the desired location.

Where is a concrete vibrator useful?

You can perform a lot of work with your hands,Beginning with minor repairs in the house and finishing with concreting of significant areas. The vibrating device not only facilitates work, but also allows to achieve the improved quality of concrete. Thanks to this, these adaptations quickly and quickly took their proper place, both in the arsenal of professional construction teams and in the workshops of domestic craftsmen. Moreover, it is not so difficult to assemble a vibrator with your own hands, and all the parts necessary for this can be easily purchased in building stores or on the market.
