Concrete shaker features and structure

A concrete vibrator is a power tool that compacts poured concrete by vibrating.

Concrete vibrator features:

Concrete vibrators use mechanical power to use certain devices as vibration sources, generate frequency vibrations, and transmit such frequency vibrations to concrete to make it compact.

The concrete poured into the formwork must be properly vibrated to reduce the friction and cohesion between the concrete particles, so that under the self-gravity effect, self-filling gaps between the grains, eliminating the air inside the concrete, The formation of pores in the post-condensation components (commonly referred to as dog holes in macropores) will not occur, and the surface of the components will be smooth and smooth without any pockmarks.

The vibro-reinforced concrete components can significantly increase the bond strength between the reinforcement and the concrete (grip force) to ensure and enhance the strength of the concrete.

The role of vibrators is not only to ensure the quality of components, but also to improve the working conditions, shorten the concrete solidification molding time, improve the use of template turnover rate, speed up the construction progress is also of great significance, is an important part of the concrete construction, widely used in construction, Municipal construction and construction, dams, bridges, ports and other projects.

Concrete vibrator structure:

Internal vibrator

Electric shaft-mounted planet vibrator concrete vibrators generally use high-frequency, outer roll, and flexible shaft connections. Mainly by the motor, transmission, vibration rod and other three major components.

Electric eccentric plug-in type concrete vibrator is driven by the motor through the flexible shaft to drive the eccentric vibrator, and rotates in the vibrating rod body to generate inertia centrifugal force to vibrate the concrete.

2. External vibrator

Electric external vibrators, also known as attached vibrators, are mainly composed of motors and eccentric vibrators, and are shaped like a motor.

3. Flat concrete vibrator

Flat-type concrete vibrators are vibrators that float directly on the surface of concrete for tamping. It is to install the attached vibrator on the flat plate. During work, the vibrating energy is transmitted from the surface into the interior through the flat-plate chassis and the concrete is tamped. This type of vibrator is mainly suitable for cement concrete pavements, bridge decks, and prefabricated prefabricated structural panels with large tap area and small thickness.

4. Shaking table

Concrete shaker, also known as desktop vibrator, is a vibration molding machine for concrete mix. The frame is generally supported on a spring, the frame is equipped with an exciter, a steel plate of the shaped product is placed on the frame, and the template is filled with a concrete mixture. Under the effect of the exciter, the frame vibrates together with the template and the mix to make the concrete compact. It is the main equipment of the prefabricated component plant produced by the short-circuit process, and is used for the mass production of hollow plates, wall plates, beam columns, drain pipes and so on.
