Pouring the foundation of a building, a concrete screed and a number of similar structures involves subsequent compaction using a special tool – a vibrator. If the work is done only once, then the acquisition of a full-fledged working device is most often completely unprofitable. It is much more expedient to do everything yourself from improvised tools. Luckily, it’s not that hard to do what you want to do.

Materials and tools needed

First of all, you need to find a drill or perforator that can serve as the basis for a future vibrator.

Materials needed for the job:

  • a rod about 15 mm thick;
  • steel pipes;
  • handle;
  • a pair of solid bearings;
  • flexible hose with a reinforced base and a layer of waterproofing material (you can also use a rubber tube);
  • cable to be placed inside the tube.

All work is carried out using a hacksaw, a welding machine, a metal drill, as well as a rod with a rectangular section.

How to DIY

When assembling a tool, it is very important to follow the correct procedure, otherwise it will probably not work to get a truly functional and efficient unit.

First, you need to find a steel pipe about 50-55 cm long and 30-40 mm in diameter. The rod is created from a metal bar with a diameter of about 15 mm. It is he who will set the system in motion and form the vibrations necessary for operation.

At one end of the bar a hole is drilled through which a training tool will be connected to the device.

The core must move without friction inside the tube, so bearings must be installed. They are hammered into the tube from both sides after the bar is inserted. Sometimes the end of the bar protrudes strongly from one of the edges. You can solve the problem by cutting off the excess length.

To protect the bearings from dust and debris, they are covered with special covers.

At the second end of the flexible rod, it is necessary to fix a sheath which hermetically hides the movable inner element.

A generalized algorithm for creating a compaction vibrator from a drill:

  1. A circular section steel rod is cut into two parts with a hacksaw or grinder.
  2. The segments are welded to a rectangular section bar on both sides.
  3. Bearings are installed at both ends to reduce friction. They must be set up out of balance.
  4. The entire assembled structure is placed inside a steel tube of the desired length.
  5. The round rod is cut on one side so that it does not protrude from the pipe.
  6. A cover is cut from sheet metal to close the tip end. This element is welded to the system using a welding machine.
  7. At the end of the rod sticking out of the tip, two holes are formed. They serve to connect with the tree. The first is located along the axis of rotation of the motor element and has a diameter of 1.5 cm, and the second is perpendicular to the first with a diameter of 4 mm at a distance of 7 mm from the end .
  8. A smaller hole is threaded to accommodate the set screw.
  9. The cable is lubricated and placed in a rubber tube. There should be a margin of about 5cm on both sides
  10. The vibrating tip is connected to the shaft.
  11. The edge of the shaft is cut and fixed in the chuck of the driven tool so that only the cable can turn.
  12. The vibrotip is closed by a plastic casing.

A simple vibrator for compacting concrete is ready. It remains only to connect the drill to the network and check the performance of the system. Everything should work evenly, providing the necessary oscillating loads to create pressure on the concrete solution.
