Small construction and home repair. We make a concrete vibrator with our own hands

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 an expensive and large concrete mixer - a household vibrator is quite suitable for them. 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 mixer can be bought in the 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 explained by the fact that any concrete solution is quite heavy and dense, because of which the air bubbles formed during the mixing process can not freely exit. 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

The concrete solution is poured into the desired shape, and the vibrator nozzle, which creates vibrations, is immersed in it. 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 by yourself: step by step instruction

1. Nozzle

Make the nozzle is better made of stainless steel. By itself, the concrete solution 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 additional rectangular. 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 projecting ends, it is necessary to make a hole, to which the drive will be attached.

3. Actuator

With the help of the bushing we connect the metal drive with the nozzle. The second end of the drive is fixed in the holder of the drill or perforator. The tool with the engine on 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 ?

With your hands, you can perform a lot of work, from minor repairs in the house and ending with concreting 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 that 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.
